Abstract

To provide a system capable of making a driver maintain strong empathy with a character, thereby continuously promoting the driver for save driving.SOLUTION: A system changes a relationship between a driver and a character and controls output of character information according to the relationship, and comprises: a function for making the relationship good; and a function for controlling an amount of change when the relationship is changed so as to be good based on information related to travel of a vehicle. The function for making the relationship good performs control such that the relationship becomes better as a degree to which a driver has been together with the device, namely a travel of travel distance, is greater. The function for controlling the amount of change performs control such that an amount of change is different from a reference change amount by which the relationship becomes better according to the degree to which the driver has been together with the device based on information related to the travel of the vehicle. Thus, even with a same travel distance, the relationship may become better early or the relationship may take time to become better.SELECTED DRAWING: Figure 13

Description

  The present invention relates to a system and program for outputting character information to a driver.

  For example, Patent Document 1 discloses a system for changing character information such as a character's expression and gestures displayed on a display screen according to the condition of a vehicle. The invention disclosed in Patent Document 1 is to show a virtual emotion assumed to have a personality by a character's expression. For example, when the driver drives wildly, if the vehicle has an emotion, it is considered that the vehicle feels offensive, so the character is angry or sad as the virtual emotion of the car. Output. Conversely, if the driver drives gently and gently, it is considered that the virtual emotions of the vehicle will be comfortable, and so an output of the expression that the character is pleased or welled is output.

  The above system urges the driver to drive safely by utilizing the emotions the driver tries to avoid making the character uncomfortable or wants the character to be pleased.

JP 2003-72488 A

  In order to support safe driving with the above-described system, it is necessary to make the driver have a feeling of desire to keep the character offensive or want to be happy. Therefore, it is necessary for the driver to strongly empress the character, but in the system disclosed in Patent Document 1, for example, the expression of the character when the driver's driving is rough or polite is the driving state It is uniformly determined according to As described above, since the expression and gesture of the character displayed on the display screen are monotonous and scarce in change, the driver is likely to get bored with communication with the character. Therefore, the driver does not maintain a strong empathy for the character, and eventually the driver may not feel anything even if the character's expression or gesture has changed. As a result, the above-mentioned system has a problem that it can not prompt safe driving.

  In addition, whether or not to empathize, for example, if the output of the character information is rich in change, the game is enhanced. Then, in an attempt to clear the game, the driver tries to drive and drive in a desired state. However, as described above, the system disclosed in Patent Document 1 has a problem that the game property is low because the change of characters is scarce.

  An object of the present invention is to provide a system and program capable of continuously promoting safe driving to the driver by maintaining strong empathy of the driver for the character.

  (1) A system according to the present invention is a system that changes the relationship with a character and controls the output of character information according to the relationship, and has a function of improving the relationship and running of a vehicle And the function of controlling the amount of change when the relationship is favorably changed based on the information regarding.

  This system is realized, for example, by an on-vehicle device fixedly installed in the vehicle, a device which is portable and brought into the vehicle at the time of driving, and the like. By outputting the character information at the time of driving, for example, a living thing such as a person or an animal is characterized to be recognized by the user. Character information is output from the system by various methods for appealing to the user's five senses (vision, hearing, touch, taste, smell). For example, the output of the character information may be performed by displaying an image of the character on a display unit (such as a display) or may be performed by outputting a voice of the character from an audio output unit (such as a speaker).

  The present system outputs character information according to the relationship with the user. The relationship is the degree of connection between the user and the character, the relationship, and the like, and may be regarded as, for example, closeness, reliability, and the like. Good relationship means that the relationship between the user and the character is good, and the relationship may be high or strong. By outputting character information according to the relationship with the character, the user can easily empathize the character, and can make the user feel as if the character is a real object.

  The character information has a good relationship, for example, by having a content such as a kind of reward which makes the user fly in variation as the relationship is good and the user is friendly and makes the user happy. Do the action to become Therefore, for example, if the mechanism is such that the relationship becomes better as traveling in safe driving, the user is further enhanced so that the relationship with the character is maintained in a good situation. , Will actively try to drive safely.

  Since the character information corresponds to the relationship, the output mode differs depending on the degree and the degree of goodness. Different output modes, such as making the output means and medium different, for example, to add audio only when the image was originally only, but to display animation of what was initially a still image or to have different costumes even for the same still image The same output means or medium may make the output contents different, such as the contents of animation may differ.

  The function to make the relationship good is, for example, to make the relationship good, that is, to make the degree of good high / strong based on the acquired predetermined information. In general, the longer you stay together, the better the relationship should be. Therefore, the predetermined information may be, for example, information on travel of the vehicle such as travel distance, and control may be performed so that the relationship becomes better as the travel distance is longer. The longer the driving distance, the longer the period of stay with the user, and the better the relationship since they drive long distances together. Also, in view of the fact that the relationship becomes better as one stays longer, for example, it may be based on the operation time. The operating time is particularly good, for example, as the time during which the engine is operating, such as from ignition on to off as vehicle information, and in this way, the user and the character were on the vehicle together. It can be considered as a ride time. In this way, the function that makes the relationship good may be controlled so that the relationship becomes better as the time spent together increases. The function to make the relationship good may be controlled to make the relationship good based on information other than the exemplified travel distance and operation time.

  When the travel distance and the operation time are compared as information for performing control to improve the relationship, the travel distance is more preferable. This means that, for example, when the vehicle is parked with the engine running, the traveling distance is 0, and when traveling for the same time as the time when the vehicle was parked and stopped, the traveling distance is extended. If control is performed to make the relationship good based on the operation time, the relationship becomes good to the same extent in both cases, but if the character is given personality, ride together on a parked vehicle. It is better to be based on the distance traveled because the character feels more happy if it is actually running than it is. Furthermore, when parked or stopped, the driver who is the user may sleep while the engine is on. Then, it is difficult to say that the character is alone and the sensitivity to the user is good. On the other hand, when the vehicle is traveling, the driver who is the user is guaranteed to be awake and to be with the character. It is preferable to be based on the traveling distance also in view of the point concerned. In addition, in the case of traveling in a city area and in the suburbs during the same time, the traveling distance is longer in the case of traveling in the suburbs where the waiting time for the signal is small and the speed is faster. If you use the expressway further, the driving distance will be longer. When traveling in the city area, there is a high possibility of traveling for activities such as commuting and shopping, and when using the suburbs and expressways, the possibility of traveling for pleasant events such as travel is also high. I can say that. Therefore, it is preferable to use the travel distance also in order to make a difference in the control for making the relationship good. Furthermore, assuming that the operation time is, for example, the present system is mounted on a portable device and the vehicle can be removed and carried around, the power supply is performed not from the battery of the vehicle but from a commercial power supply etc. The system can be operated with the power on regardless of travel. Then, even if the user is away from the portable device in such a power-on state, the operation time is added and control becomes good, which is not very preferable. Therefore, it can be said that it is fair and preferable to perform control to improve the relationship based on the travel distance.

  Since it has a function to control the amount of change when the relationship is favorably changed based on the information on the travel of the vehicle, for example, it becomes an opportunity to perform the good control to acquire the function to make the relationship good. Even if the predetermined information is the same, if the amount of change based on that is different, the degree and degree of goodness of the relationship are different. Therefore, even if the input information (the predetermined information acquired above) is the same, the output result may be different, so it is interesting and the system is rich in game characteristics. Further, since the control of the amount of change is performed based on the information on the traveling of the vehicle, the amount of change becomes larger or smaller depending on the actual driving of the driver. Therefore, the greater the amount of change, the more efficiently the relationship is improved. Therefore, the driver who is the user works to drive such that the amount of change is increased when trying to improve the relationship.

  The control of the amount of change is performed, for example, in consideration of a predetermined parameter with respect to input information (the acquired predetermined information described above) from which the relationship is made favorable. The addition is, for example, multiplication by a parameter (coefficient), or addition / subtraction of a parameter (predetermined value) each time a certain amount of input information is obtained. Further, the amount of change may be changed according to a predetermined function, or the amount of change may be changed according to a predetermined rule.

  (2) The character information may be a reward for the user to be satisfied as the relationship is better. In this case, although described in (1), the user is strongly motivated to operate or drive to maintain a good relationship or to obtain a better relationship so as to receive rewards. Become.

  (3) It is good to provide the alerting | reporting means which alert | reports the information regarding the said present variation in the function which controls the said variation. The information on the amount of change may be the amount of change itself, or information corresponding to the amount of change or information specifying the amount of change. In an embodiment, this change corresponds to the correction factor. By the user knowing the current change amount, it is immediately understood how the change amount is changed / reflected according to the current driving method and the driving condition, for example, the change amount is small when the driving operation is performed or You can know if you grow up. Therefore, the user can take a driving operation such that the amount of change becomes larger. Also, by informing the user of the present amount of change, it is possible to make the user motivate to maintain the state as it is or to make the amount of change better.

  (4) The informing means may include a display area indicating information on the amount of change. (5) In that case, the display area may be an indicator. Such an indicator system is preferable because the current state of change amount can be known at a glance by its length. The display method of the display area is not limited to the indicator, and may be represented by a numerical value or the like.

  (6) Further, it is preferable that the notification means correspond the information on the amount of change to the character posture. It is preferable that the change in the character's posture is a kind of reward that is more familiar to the user as the amount of change is larger and that makes the user happy. The change in posture includes, for example, changing the facial expression, changing the animation operation, changing the size, changing the display color and transparency of the character, and the like. The change in facial expression includes, for example, “smileing” → “normal” → “appealingly” → “mushing” from the side with the largest amount of change. The animation motion is, for example, a motion animation that is larger as the amount of change is larger, or it is an animation that dances to express joy or pleasure. In addition, the smaller the amount of change, the smaller the motion, the motionless, or the depression. By using the change in the character's posture, it is easy for the user to accept the current amount of change in a straightforward manner, unlike the notification using inorganic indicators or numerical values. Then, for example, when the character has a sad face in a control state in which the amount of change is small, one of the factors for keeping in mind that the user is in a control state in which the amount of change is large in order to make the character laugh Become. And although the change of the character's form may be performed independently, it is good to interlock | cooperate with the alerting | reporting by an indicator other display area. Since it is not possible to gaze at the display unit for a long time during driving, it is better to understand if the character's posture changes as auxiliary information of notification in the display area such as an indicator.

  (7) The function to make the relationship good is to perform control such that the higher the degree with the machine, the better. The function to control the change amount is actually based on the information related to the traveling of the vehicle. It is preferable that control be performed so as to have a change amount different from the reference change amount that changes better according to the degree with the machine.

  This machine is a device etc. on which this system is implemented. The degree with which the user is with the machine is higher, for example, the connection between the user and the character becomes stronger and more intimate, and the reliability from the character also increases, and the relationship is Since it can be inferred that it will become stronger, control is performed so that the relationship becomes better as the degree with the unit increases. The degree to which the vehicle is used is determined based on, for example, the traveling distance, the operation time, the driving time, various acquired driving situations, and the like. For example, in the case of travel distance, control is performed such that the relationship becomes better as the total travel distance becomes longer, and in the case of operation time, the relationship becomes better as the total time of power on of the machine becomes longer. Control to be

  Assuming that the standard amount of change in which the degree and degree of good change according to the degree with the machine is the reference amount of change, the function of controlling the amount of change actually changes the amount of change from the reference amount of change. The change in the degree of goodness or degree of the relationship obtained by running the vehicle may be different from the degree or degree of goodness of the relationship obtained based on the degree actually with the machine Come out.

  (8) It is preferable that the function of controlling the variation is to perform positive assessment processing to make the variation larger than the reference variation and negative assessment to make the variation smaller than the standard processing. . In this way, the relationship becomes so good that it can not be obtained by ordinary running, and the good growth of the relationship is bad, so that the game becomes more interesting as a game. By driving so as to be a positive assessment process, the degree of goodness of the relationship is increased in a short period of time, and character information corresponding to that is output. Therefore, even if the driver does not drive very much, better character information can be obtained by paying attention to the driving operation, and, as will be described later, even if the relationship is lowered due to some factor, the relationship is short. The degree of goodness of

  (9) The amount of change smaller than the reference processing may include negative values. In such a negative state, as the vehicle travels, the relationship is controlled to be worse than the current state. By providing such a negative value, the user does not at least perform a driving operation to become a negative value, so, for example, when performing a dangerous driving with a large degree or when no improvement in driving is observed, the amount of change It is good to make it a negative value, for example, by repeating the state and situation where the becomes smaller.

  (10) The function of controlling the amount of change may reduce the amount of change when the acquired information on the travel of the vehicle does not satisfy the setting condition, and return to the original size after a predetermined period has elapsed. The predetermined period is, for example, a predetermined period which has been set, or a period in which traveling of the set predetermined distance is completed. The method of returning to the original size may be, for example, gradually returning the smaller amount of change with a time constant or the like, or maintaining the amount of small amount for a predetermined period and then returning at once. In the case of gradual return, it may be continuous or stepwise.

  In this way, when the setting condition is not satisfied once and the amount of change becomes small, even if the setting condition is satisfied immediately after that, the condition is not returned immediately, but the amount of change is kept small for a predetermined period. For example, dangerous driving, traffic violation, etc., which is not preferable driving, may occur even momentarily for a short time, which may lead to an accident or the like, so it is preferable not to be in the state during driving period. Therefore, since the user will keep in mind driving that does not satisfy the setting condition even if it is instantaneous or the like, it is preferable because the setting condition can contribute to safe driving and the like. Furthermore, even if the setting condition is not satisfied even once, the operation does not return to the original state until a certain period of time elapses even if the operation satisfies the setting condition, which causes a penalty and a game element may appear.

  (11) Based on the invention of (10) above, the function of controlling the amount of change has a larger amount of change when the acquired information on travel of the vehicle satisfies the setting condition as the setting condition becomes more severe. It is good to do.

  If the setting conditions are severed, there is a disadvantage that a small change amount occurs for a certain period without satisfying the setting conditions due to a slight difference in driving operation etc. However, if the setting conditions are satisfied, the large change amount continues As a result, the degree and degree of goodness of the relationship rise in a short period of time, and various character information can be obtained according to the relationship. Therefore, it becomes like high risk and high return, and the game is enhanced. In addition, not only the game nature is simply increased, but driving that meets more stringent setting conditions is usually safer and more environmentally friendly, such as safe driving or eco driving, for example. As it is often the case, it is preferable to the traffic environment.

  The reduction range of the change amount when the setting condition is not satisfied may be constant regardless of whether the setting condition is severe or not, and the reduction range may be different according to the degree of difficulty of the setting condition. Further, the control of the variation when the setting condition is satisfied when there are a plurality of sets of the information about the traveling of the vehicle and the setting condition exists, for example, the setting condition of each set when the setting condition of all the sets is satisfied. It is preferable that the sum of the increase width of the change amount set in accordance with the degree of difficulty of the control be performed to reduce the change amount if the condition is not satisfied even with one setting condition. Further, as another method of controlling the change amount, for example, an amount to be raised when the setting condition is satisfied and an amount to be decreased when the setting condition is not set are set for each set, and whether the set setting condition is satisfied or not A variety of methods may be adopted as a judgment and comprehensively determining the amount of change.

  (12) Based on the invention of the above (11), an input screen for designating relative levels of a plurality of levels is displayed as an interface for inputting the setting conditions, and for each level of the plurality of levels of the input screen The setting condition may be related to the amount of change when the setting condition is satisfied. The user only needs to specify multiple levels from “hard (hard)” to “loose (easy)”, and can intuitively specify setting conditions. Also, under the current setting conditions, if the conditions are not often satisfied, the setting conditions are relaxed by one or more steps, and conversely, if the setting conditions are always satisfied, the setting conditions are tightened by one or more steps Can be adjusted to increase the amount of change, making it easy to set appropriate conditions.

  (13) Based on the inventions described in (10) to (12) above, it is preferable to make the predetermined period zero immediately after engine start. By setting the predetermined period to 0, it is possible to make the standard change amount set immediately. For example, if it is determined for each unit time (for example, one second) whether or not the setting condition performed during traveling is satisfied, information on traveling of the vehicle to be the determination target is acquired at least for each unit time. And the determination process will be performed. Therefore, normally, the determination during traveling is stored in a volatile storage unit such as a RAM and the determination processing is appropriately performed. Therefore, since the information related to the travel of the vehicle immediately before the stop stored in the volatile storage unit is not held together with the engine stop (ignition off), immediately after the engine is started, whether the information related to the travel of the vehicle can not be obtained May not meet. Therefore, even if the setting condition is not satisfied, it is possible to immediately return to the standard amount of change by setting the predetermined period to zero.

  For example, when information regarding travel of a vehicle is stored in the non-volatile storage unit, the determination processing is performed immediately after the start based on the information regarding travel of the vehicle stored in the non-volatile storage unit. Although it is not necessary to provide the information, as described above, if the information on the travel of the vehicle is updated in a short cycle unit time, the upper limit of the number of times of rewriting of the non-volatile storage unit is reached immediately. It is preferable that the problem immediately after the start of the engine can be resolved by a simple process of setting the predetermined period to zero.

  If the number of times the non-volatile storage unit can be rewritten greatly increases, or if a backup power source or the like is installed to hold information on vehicle travel stored in the volatile storage unit even if the engine of the vehicle is stopped , They may be used.

  (14) On the premise of the inventions of (10) to (13) above, it is preferable to have a plurality of sets of acquired information on traveling of the vehicle and setting conditions, and the setting conditions may be set for each set. Several sets may differ in both the information regarding driving of a vehicle, and setting conditions, and one may be common. For example, when it is determined that both a sudden start and a sudden stop are determined, both can be detected by the acceleration applied in the traveling direction of the vehicle, so the information related to the traveling of the vehicle becomes one acceleration and an output of the sensor Therefore, the setting conditions are different, and there are two sets. The same applies to the case of detecting the left and right sharp steering wheel operations.

  For example, depending on the user's driving habit, the characteristics of the vehicle, the condition of the road on which the vehicle is traveling, the installation position of the machine equipped with this system, etc. , May not be. Therefore, by setting the setting conditions individually, it is possible to increase the amount of change while satisfying the setting conditions of all sets.

  (15) It is preferable that the character information includes one that is output probabilistically, and the relationship affects the probability. In this way, the probability of the predetermined character information being output is influenced by the relationship, so the game is more interesting.

  (16) Based on the invention of (15) above, it is preferable that the probability is higher as the relationship is better. This is preferable because the user tries to make the relationship better. The increase in probability may be made to increase continuously in response to the increase in degree of goodness of the relationship or may be made to increase continuously in each predetermined range.

  (17) Based on the inventions of (15) and (16) above, the character information differs depending on the time zone, and the time zone includes a normal operation time zone and an unordinary (standby) operation time zone. In the abnormal operation time zone, it is preferable to output character information of the normal operation time zone based on the probability. The time zone may be divided into, for example, a daytime zone and a nighttime zone, or may be further divided into three or more zones. For example, when dividing into a daytime zone and a nighttime zone, since the character goes to bed at night, the daytime zone becomes a normal operation time zone and character information according to the relationship is output, but The time zone is an unusual operation time zone, and it is possible to output character information indicating a lying state regardless of the relationship. In the case of such an aspect, for a user who operates mainly at night, since character information indicating a sleeping state is output, the user lacks interest. In such a case, the operation time zone may be set to be reversed between day and night, but the normal operation such as output of character information based on the relationship even if the character wakes up by probability and is in an unusual operation time zone The ability to do this will make the game more interesting as it works several times a night, even at night. And game nature increases more by associating the operation probability with the relation. In particular, if the probability is increased as the relationship gets better, the user tries to keep the relationship better, which is preferable.

  (18) When the set condition is satisfied, it is preferable that the character information is not output until the return condition is satisfied. The return condition is, for example, a fixed condition such as elapse of a predetermined time or traveling of a predetermined traveling distance, or provision of a predetermined item. The predetermined time may be, for example, the operating time of the present system or the elapsed time in the real world. When the character information is not output, the user can not meet the character and becomes sad. Also, even if character information is not output once, for example, character information is output again if the fixed condition is cleared, but if it does not wait for the fixed condition to be cleared, for example, provision of an item etc. By incorporating a mechanism in which character information is output under a special return condition, the user performs an action for acquiring an item, and the game is enhanced. For example, the item is obtained by actually moving to a predetermined place, or accessing a predetermined server / site and obtaining for free or for free.

  (19) A function may be provided to perform control to deteriorate the relationship. As described above, in the present invention, the basic configuration is to perform control to make the relationship good and to control the amount of change to make the relationship good. And there is a control which worsens the relationship by, for example, directly deducting the degree and the degree of goodness of the relationship, etc. at once. For example, if the control that worsens when the set deduction condition (predetermined speed exceed 3 times in a row) is satisfied, the relationship stored up to now will collapse at once, and the user is concerned. It can be expected that efforts will be made so that nothing will happen. Therefore, it is preferable that the demerit condition be matched to an operation or the like that is more undesirable than the condition for performing control to reduce the amount of change. Also, as in the invention described in (9) above, making the amount of change negative may be regarded as one aspect of the function of performing control that deteriorates. In that case, the function of controlling the amount of change is also used as the function of performing control to deteriorate this relationship.

  (20) The function of controlling the amount of change preferably performs control to increase the amount of change in the case of safe driving. (21) The function of controlling the amount of change preferably performs control to reduce the amount of change when not in safe operation. In this way, safe driving can be recommended to the user.

  (22) The function of controlling the amount of change may be performed based on an operating state. Driving conditions include, for example, undesirable driving conditions such as sudden acceleration (starting and traveling), rapid deceleration (stopping and traveling), dangerous operation such as sudden steering (suduous turning), and non-eco operation etc. is there. When a particularly undesirable operating state is detected, control may be performed to reduce the amount of change.

  (23) Based on the invention of the above (22), the driving state is a rapid acceleration (starting and traveling) obtained from the acceleration in the traveling direction of the vehicle, and a rapid deceleration obtained from the acceleration in the traveling direction of the vehicle (During traveling), at least one of sudden changes in traveling direction obtained from acceleration in a direction crossing the traveling direction of the vehicle.

  (24) On the premise of the invention of (23) above, it is preferable that the sudden change of the traveling direction is distinguished by right turn and left turn. For example, if the installation position of the means for detecting acceleration (for example, the acceleration sensor) (the installation position of the machine when incorporated in the machine) is shifted to the right or left of the vehicle, the vehicle turns at the same acceleration around the vehicle. Even then, the value of acceleration differs depending on the turning direction. Therefore, by changing the setting conditions according to the installation position, it is possible to open the trouble due to the difference in the installation position.

  (25) In the function of controlling the amount of change, the amount of change may be reduced under certain conditions in the case of traffic violation. In this way, the user can expect to drive in an effort not to violate traffic.

  (26) Given the invention of (25) above, the certain condition may be the same kind of violation in the same place. The same type of violation in the same place may be, for example, a suspension violation at the same point or an overspeed at the same point. Repeating the same type multiple times at the same place is not as alert and may be worse off than the first time, so the amount of change will be smaller if repeated multiple times.

  (27) Based on the inventions of (25) and (26) above, it is preferable that the certain condition does not reduce the amount of change in the first violation. The first violation gives grace without reducing the amount of change. As a result, the user's motivation can not be lowered by not reducing the amount of change, and it is possible to be careful not to violate the user, and as a result, it is possible to promote safe driving. It is good to warn at the time of the first violation.

  (28) Based on the inventions of (25) to (27) above, it is preferable to reduce the amount of change with N or more violations as a certain condition. For example, in the case of a violation such as an overspeed, it is difficult to immediately return to below the speed limit even if the overspeed is noticed, and it is dangerous to suddenly reduce the speed below the speed limit as it suddenly decelerates. On the other hand, if overspeed is continuously continued for a fixed period, it can be estimated that there is no intention to decelerate and keep the speed limit, and it is dangerous operation. Therefore, it is better to reduce the amount of change for the first time after N or more violations. At this time, it is preferable to perform warning etc. up to [N-1] times.

  (29) The extent to which the amount of change is reduced may be changed in accordance with the degree of violation of (25) to (28) above. For example, even if the same speed overrun is violated, the speed overrun is more dangerous as the overspeed from the speed limit is greater, and it can be said to be malicious. Therefore, it is better not to lower the change amount as the same overspeed violation but to increase the decrease amount of the change amount as the degree of violation is larger. Here, to change the degree of reduction of the change amount, for example, it is preferable to change the absolute amount when reducing the change amount once when a violation occurs, according to the degree of the violation. For example, the greater the degree of violation, the greater the absolute amount of lowering. Further, as another example of changing the reduction degree of the change amount, even if the reduction amount of the change amount at the time of the violation is the same, the time required to return to the normal change amount may be extended. For example, as the degree of violation is higher, it is better to extend the time required for the return. As yet another example, the increase of the change amount may be delayed until it returns to the normal change amount. These controls may be implemented in combination.

  (30) Based on (29) above, the degree of violation is the overspeed exceeding the first reference speed, and the overspeed when the second reference speed exceeding the first reference speed is exceeded. It is preferable to lower the amount of change according to the degree of reduction more than the degree of reduction. The first reference speed may be, for example, a speed limit or a speed obtained by adding a predetermined margin (for example, 20 km / hour) to the speed limit. Then, the second reference speed may be, for example, a speed at which a one-shot suspension and stoppage occurs (more than 30 km per hour). An overspeed condition that results in a single-stop operation can be said to be a very dangerous driving condition leading to a major accident. In such a driving state, the feeling of the character assuming that the character also has a personality is extremely feared, for example, as compared with the case of slight overspeed, and the intimacy and reliability with respect to the driver user are also lowered. There is. Therefore, when the second reference speed is exceeded, the amount of change is greatly reduced, that is, a very small value. With such a setting, on the contrary, the user operates with caution so as not to cause such a situation, and as a result, the safe driving is performed without exceeding the above-mentioned second reference speed. Can be

  (31) Based on (30) above, the first reference speed may be a speed obtained by adding a set speed to the speed limit. The set speed may be, for example, 20 km per hour. When driving according to the driving of a surrounding vehicle, the speed limit may be unexpectedly exceeded. In this case, if only the host vehicle travels in compliance with the speed limit, it will lead to a dangerous state. Therefore, even if the speed is exceeded slightly, the change amount is not reduced. It is possible to drive according to the flow of surrounding vehicles.

  (32) In the case of a highway where the speed limit is less than a predetermined value, the first reference speed may be a speed higher than the speed obtained by adding the set speed to the speed limit. The predetermined value may be, for example, the speed limit of a general expressway such as 80 km / h. The high speed may be, for example, 100 km per hour.

  In general, the speed limit of expressways is 80 km / h or 100 km. On the other hand, for example, there is one in which the speed limit is set to 60 km, which is slower than the speed limit of a general expressway, such as the Metropolitan Expressway. The surrounding vehicles may travel at a speed similar to or near the speed limit of a general expressway (for example, 90 to 100 km / h). In such a case, it is important to observe the traffic rules, but if only the host vehicle is traveling at the speed limit of 60 km, the speed difference with other vehicles is 30 to 40 km per hour, which is dangerous. Therefore, safe driving can be promoted by preventing the amount of change from becoming small even when traveling according to the surroundings.

  (33) Based on the inventions described in the above (23) to (32), if the same kind of violation is made as a warning next, it is predicted that the amount of change will decrease, and if the same kind of violation is made next, the above change You may want to lower the amount. It is possible to urge the user not to violate the warning by warning instead of suddenly reducing the amount of change. If the same violation was made in spite of the warning, the advice from the character was ignored, and control was made to reduce the amount of change. This corresponds to, for example, control in which the correction coefficient is not lowered in the first suspension violation in the modification.

  (34) Based on the inventions described in (23) to (33) above, after reducing the amount of change, it is preferable to recover the original amount of change with a predetermined function (algorithm, rule). (35) The predetermined function may delay recovery as the degree of violation increases. The degree of violation may be, for example, the degree of overspeed, such as the degree of the violation in one violation, or the degree of viciousness such as repetition of the same violation in the same place. The higher the degree of violation, the worse the closeness / reliability of the character to the user. Therefore, by delaying the recovery, a state in which the change to the extent of the relationship becomes good continues for a long time, and the elongation to the extent of the relationship becoming the good becomes lower. Moreover, although it is not a traffic violation, it is related also when control which becomes small based on the state of driving, such as acceleration exceeding a threshold, is performed like the invention described in (22)-(24). If it is repeated, it is good to delay recovery. For example, if driving with poor comfort etc. is repeated, the user's mentality when the character is given personality and emotion also worsens, and it takes a long time to recover mood, so the original amount of change is restored. It is good to take a long period of time to do it.

  (36) The function of controlling the amount of change may be performed based on the eco-driving situation. The eco-driving is determined based on, for example, fuel consumption. For example, control is performed to increase the amount of change in the case of eco-driving, and to reduce the amount of change in the non-eco operation. In addition, if the eco driving is positive, the change is increased, but if it is not the eco driving, the changing amount is not changed (the negative assessment is not performed), or if the eco driving is not changed, the changing amount is not changed If it is not eco-driving, you may make a negative assessment to reduce the amount of change. If eco driving is used, it consumes less fuel and is economical, and it is environmentally friendly, and its speed change is small, so the ride is also good, so it is assumed that the character has a personality. 'S emotions are joy, and it can be said that the intimacy and credibility with the user is improved. Therefore, the amount of change is controlled based on the status of eco-driving.

  (37) It is preferable to set an installation point of an item that affects the state of the character on a map, and to get the item with a certain probability when the vehicle goes to the location of the installation point. For example, it is preferable to use the acquired item to affect the state of the character, and the item may be saved. The state of the character affects the output of character information, which may increase the game nature. A certain probability may be 100% (always given), or if there is a situation where it is not given (less appearing) as less than 100%, the game may be more enhanced. This probability may be fixed depending on the type or place of the whole or each item, or may change depending on the degree or degree of the goodness of the relationship at that time.

As items to get,
・ Improve the relationship (relationship is up, bonus points, etc.)
・ The amount of change does not decrease / rises / returns to the standard. ・ Returns from the screen off state (appears on the screen)
The probability of the invention described in (15) or the like is increased. For example, the process of executing the above-described process and the process of making the above-described process in an executable state may be performed according to the type of the item. As a process for making the above-described process executable in accordance with the type of item, for example, it is preferable to store the type of the item acquired. Then, processing regarding the type of the stored item may be performed at a predetermined timing.

  (37) A setting point of an item which affects the state of the character is set on a map, and when the vehicle goes to the place of the setting point, it has a function of acquiring the item with a set probability. The get may be conditioned on the vehicle stopping at the installation point.

  (38) A program according to the present invention is a program for causing a computer to realize the function of the system according to any one of (1) to (37).

  According to the present invention, it is possible to provide a system capable of continuously promoting safe driving to the driver by maintaining strong empathy of the driver for the character. Moreover, the character information to be output is in accordance with the relationship with the character, and in order to control the amount of change when the relationship is favorably changed based on the information regarding the traveling of the vehicle, for example, the travel distance etc. Different character information is output if the traveling state of the vehicle is different, even if the degree of being with the machine is the same. Therefore, since the character information to be output changes depending on the manner of driving of the vehicle of the user, the game property is also enhanced. Furthermore, it is possible to urge the user to perform operation such that control to increase the amount of change is performed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. These drawings are used to explain the technical features that can be adopted by the present invention. The configuration of the described apparatus, the flowcharts of the respective processes, and the like are not intended to be limited thereto, but merely illustrative examples.

"Basic configuration of electronic equipment"
FIG. 1 and FIG. 2 show the configuration of a radar detector which is a preferred embodiment as an electronic device constituting the system of the present invention. The radar detector 1 is provided with a thin rectangular case main body 2 and is affixed and fixed on a dashboard or the like of a vehicle using a bracket 3 attached to the lower side of the rear side of the case main body 2.

  A display unit 5 is provided on the front surface of the case body 2 (the surface facing the rear (vehicle side) of the vehicle). The display unit 5 is configured of a 3.2 inch color dot matrix TFT liquid crystal display. A touch panel 6 is provided on the display unit 5 to detect which part of the display unit 5 has been touched. Further, a volume adjustment button 7 is disposed on the right side of the front of the case main body 2, and various operation buttons 8 are disposed on the left side.

  The right side surface of the case body 2 is provided with a card insertion slot 9 for mounting a memory card as a removable recording medium, and a memory card reader 10 is incorporated inside the card insertion slot 9 in the case body 2 . By inserting the memory card 11 from the card insertion slot 9, the memory card 11 is attached to the card reader 10. The card reader 10 internally takes in data stored in the mounted memory card 11. More specifically, the data stored in the memory card 11 includes update information such as new alarm target information (position information such as latitude and longitude, type information, etc.), and the update information is transmitted via the control unit 18 It is stored (downloaded) in a database 19 built in the device, and data is updated.

  The database 19 can be realized by a non-volatile memory (for example, an EEPROM) externally connected to the microcomputer in the controller 18 or the microcomputer. The memory card 11 itself may be configured as part or all of the database 19. In the database 19, map data and information on a certain alarm target are registered at the time of shipment, and data and the like on the alarm target added thereafter are updated as described above.

  The GPS receiver 13 is disposed inside the rear upper center of the case body 2, and the microwave receiver 14 and the wireless receiver 15 are disposed next to the GPS receiver 13. The GPS receiver 13 receives a GPS signal from a GPS satellite and outputs current position (latitude and longitude) information. The microwave receiver 14 receives microwaves of a predetermined frequency emitted from the velocity measuring device. The wireless receiver 15 receives a UHF band radio wave for traffic control communication. A speaker 16 is also incorporated in the lower part of the case body 2. The speaker port is provided on the bottom of the case body 2.

  A DC jack 17 is disposed below the back side of the case body 2. The DC jack 17 is for connecting a cigar plug cord (not shown), and is connected to a cigar socket of the vehicle via the cigar plug cord so that power can be supplied.

  The acceleration sensor 22 is disposed at a predetermined position on the inner surface of the case body 2. The acceleration sensor 22 detects the behavior of the vehicle, and detects an acceleration applied to the X axis in the traveling direction, an acceleration applied to the Y axis in the lateral direction, and an acceleration applied to the Z axis in the vertical direction. As a result, the X-axis detects a predetermined acceleration / deceleration, the Y-axis indicates a sharp steering wheel, and the Z-axis detects a predetermined behavior of the vehicle, such as riding on a step or falling into a depression.

  In the case body 2, an OBD adapter 21 is detachably mounted on the OBD-II (II is a Roman numeral "2", hereinafter "OBD-II" is described as "OBD 2") connector mounted on the vehicle. Is connected. The OBD 2 connector is also referred to as a failure diagnosis connector, is connected to the ECU of the vehicle, and outputs various vehicle information periodically. Therefore, the control unit 18 periodically acquires various types of vehicle information by connecting the OBD adapter 21 and the OBD 2 connector on the vehicle body side.

  The vehicle information includes the vehicle speed of the vehicle, the injection injection time, the intake air amount, the information of the remaining fuel, and the like. The remaining fuel is the amount of fuel remaining in the current fuel tank and is output at a resolution of 0.5 liters. Therefore, by acquiring the remaining fuel periodically and recording the timing at which the change occurred between the previous remaining fuel and the current remaining fuel, it is consumed from the previous change occurrence to the current change Fuel can be said to be 0.5 liter. In addition, there are also cases in which information on fuel consumption (information on lifetime fuel consumption, current fuel consumption, instantaneous fuel consumption, etc.) is output periodically.

  The OBD adapter 21 described above is detachably cooperated with the connection terminal 23 provided in the case main body 2. When the vehicle information from the OBD 2 connector is unnecessary, removing the OBD adapter 21 can suppress the wiring from being scattered on the dashboard and the like, and the surroundings of the radar detector can be clarified.

  The control unit 18 is a microcomputer including a CPU, a ROM, a RAM, a non-volatile memory, an I / O, etc., and is connected to the above-described units as shown in FIG. The control unit 18 creates information to be notified to the driver based on the information input from the various input devices described above (the touch panel 6, the GPS receiver 13, the microwave receiver 14, the wireless receiver 15, etc.) Information is output using an output device (display unit 5, speaker 16, etc.). These basic configurations are basically the same as conventional ones.

  The functions of the radar detector 1 of the present embodiment are stored in the EEPROM of the control unit 18 as firmware executed by the CPU of the control unit 18 and are implemented by execution of the CPU in the control unit 18. The firmware stored in the EEPROM can be updated by new firmware stored in the memory card.

  The main information output from the output device of the radar detector 1 as the driving support system is alarm information for urging the driver to be safe. The alarm information is output, for example, in the following case. The control unit 18 obtains the distance between the target object (latitude and longitude) stored as map information in the database 19 and the current position (latitude and longitude) of the vehicle detected by the GPS receiver 13, and the obtained distance is When the distance becomes equal to or less than a predetermined distance, alarm information is output from the output device. In addition, for example, the control unit 18 outputs alarm information from the output device when the microwave receiver 14 detects a signal corresponding to the microwave in the frequency band emitted from the velocity measurement device. The radar detector 1 causes the driver to recognize a dangerous place where a traffic accident is likely to occur by outputting alarm information. Thereby, the radar detector 1 can urge the driver to drive safely. Note that the above-described alarm information is an example, and in fact, various other alarm information are output to the driver.

(Display mode)
FIG. 3 shows the display mode of the radar detector 1. The control unit 18 displays the screen on the display unit 5 in a different manner according to the set display mode. The control unit 18 has a radar standby display mode, an OBD display mode, and a MAP display mode as a constant mode. The radar standby display mode includes a screen showing the clock and speed (see FIG. 4), a screen showing the GPS positioning status (see FIG. 5), a screen showing the tilt state of the vehicle, and a screen showing the acceleration applied to the vehicle Is displayed on the display unit 5. In OBD display mode, instantaneous fuel consumption, current fuel consumption, fuel flow rate, vehicle speed coolant temperature, trip meter, national road average fuel consumption, general road average fuel consumption, highway average fuel consumption, engine speed, engine load factor, throttle opening etc. In this mode, a screen (see FIG. 6) shown is displayed on the display unit 5. The MAP display mode is a mode in which a map near the vehicle is displayed on the display unit 5 (see FIGS. 7 to 9). The switching of the display mode is performed based on the pressing of the work button 8. That is, each time the upper work button 8 is pressed, the control unit 18 switches the display mode in a predetermined order.

  An alarm display mode which is a display mode when alarm information is output will be described. In the radar standby display mode and the OBD display mode, telops indicating alarm information are superimposed and displayed on the screen corresponding to each constant display mode, and a warning sound is output from the speaker 16. On the other hand, in the MAP display mode, the output mode of the alarm information can be switched to an animation mode, a shooting mode (hereinafter, these are collectively referred to as a non-character mode), and a character mode. The control unit 18 switches the character mode and the non-character mode alternately in response to the pressing of the lower work button 8. As shown in FIG. 7, in the animation mode, the control unit 18 superimposes and displays the animation 101 of the target object or the velocity measuring device on the map 100 and outputs a warning sound from the speaker 16. As shown in FIG. 8, in the photographing mode, the control unit 18 superimposes and displays the target object and the photographing (REALPHOT) 102 of the velocity measuring device as alarm information on the map 100 and outputs a warning sound from the speaker 16. As shown in FIG. 9, in the MAP display mode-character mode, the control unit 18 superimposes and displays the character 104 on the map 100. Further, the control unit 18 outputs the voice of the character 104 from the speaker 16. Alarm information is notified to the driver by the behavior and voice of the character 104.

  The radar detector 1 as the driving support system in the present embodiment is characterized in the operation in the character mode (within the thick frame in FIG. 3) in the MAP display mode. When the radar detector 1 operates in the MAP display mode-character mode, the character 104 may be displayed on the display unit 5 even if it is not necessary to notify the driver of the alarm information. The character 104 behaves as if it is a real person and communicates with the driver by talking to the driver. In addition, the character 104 changes behavior and voice according to closeness, which is an example of the relationship with the driver. Thereby, the radar detector 1 guides the driver to strongly empathize the character 104. Furthermore, the character 104 outputs not only notification of a dangerous place where a traffic accident is likely to occur, but also warning for dangerous driving, violent driving, driving without concentration, drowsy driving, etc. as alarm information. A driver who wants to deepen the degree of empathy for the character 104 positively tries safe driving in response to the alert from the character. The radar detector 1 prevents the driver from getting bored with communication with the character by developing and maintaining the driver's degree of empathy for the character to a high level, and continues safe driving for the driver. Can be encouraged.

  In addition, the above-mentioned display mode (a regular display mode and an alarm display mode) is an example, and the present invention may operate in other display modes. For example, the character may be displayed on the display unit 5 in the radar standby display mode or the OBD display mode.

(Information stored in storage unit 19 etc.)
The details of the information stored in the database 19 will be described with reference to FIG. The database 19 stores output information, map information, and setting information. The output information is various information output from the output device. The output information includes standby information, event information, logo information, still screen information, activation information, and setting screen information. The event information notifies the driver of various events when it is determined that the vehicle state or the driving state is a predetermined state (hereinafter referred to as an event occurrence time) based on the information input from the input device Information that is output from the output device in order to The standby information is information output from the output device in a state where an event has not occurred (hereinafter referred to as a standby state). The logo information, the still screen information, and the activation information are information that is first output from the output device when the radar detector 1 is activated in the state of being set to the MAP display mode-character mode. The setting screen information is information of a screen displayed on the display unit 5 when the driver performs a setting input operation on the radar detector.

  The standby information and the event information include image information to be displayed on the display unit 5 and audio information to be output from the speaker 16. The standby information and the event information include a plurality of pieces of information for each constant display mode. Specifically, the standby information is radar standby information output when operating in the radar standby display mode, OBD information output when operating in the OBD display mode, and output when operating in the MAP display mode-non-character mode Provided with non-character information. The event information includes radar standby information output when operating in the radar standby display mode, OBD information output when operating in the OBD display mode, character information output when operating in the MAP display mode-character mode, And MAP display mode-includes non-character information output when operating in non-character mode.

  The map information is information for displaying the map 100 on the display unit 5 and includes, in addition to normal map data such as a road network, information on a target object, traffic rule information and the like. The information on the target object is information in which information indicating the type of the target object, latitude and longitude indicating the position of the target object, animation or photographed image displayed on the display unit 5, and sound output from the speaker 16 are associated. Target targets include fixed speed measuring devices (including radar-like velocity measuring devices that emit radar waves (microwaves) and velocity-measuring devices that do not emit radar waves such as loop coils), drowsy driving accident point, radar, Limiting speed switching point, control area, inspection area, inspection area, N system, traffic monitoring system, intersection monitoring point, signal disregard deterrence system, police station, accident frequent occurrence area, on-vehicle aim frequent occurrence area, sudden / continuous curve ( Expressway), junction / joining point (highway), ETC lane advance guidance (highway), service area (highway), parking area (highway), highway oasis (highway), smart interchange (highway), PA / SA Gas station (highway), tunnel (highway), highway radio reception area (high speed Road), prefectural border announcement, road station, view point parking etc.

  The traffic rule information is information on traffic violations. Information on traffic violations includes information on suspension and information on speed limit. The information on the suspension includes position information that specifies the location to be paused. The place to be paused is at least position information for specifying a place where a road sign specifying the pause is installed. The information on the speed limit is information specifying the speed limit and the road on which the speed limit is set. The information for specifying the road includes position information for specifying the position of the road, the road type (highway / general road), and the like.

  The setting information is information indicating various operation conditions of the radar detector 1. The control unit 18 determines operating conditions based on various setting information stored as setting information, and performs various processes based on the determined operating conditions.

  The details of the information stored in the RAM in the control unit 18 will be described with reference to FIG. The RAM stores, for example, current date and time, vehicle position coordinates, correction information, corrected total travel distance, familiarity, surrounding information, driving state, OBD information, and event flag.

  The current date and time is information indicating the current date and time. The current date and time is specified and stored based on date and time data included in the GPS signal from the GPS satellite received through the GPS receiver 13. Vehicle position coordinates are coordinates (latitude and longitude) indicating the current position of the vehicle. Vehicle position coordinates are identified based on GPS signals received via the GPS receiver 13. The history since the engine was turned on is stored.

  The correction information is various types of information for correcting the actual travel distance to obtain a corrected total travel distance. The correction information includes a correction coefficient, a travel distance of a predetermined period, and the like. The correction coefficient is a coefficient for obtaining a corrected total travel distance for obtaining a closeness, which will be described later. The correction coefficient is obtained by the control unit 18 based on the information on the traveling of the vehicle. Details will be described later.

  The corrected total travel distance is information obtained by correcting the actual travel distance of the vehicle based on a predetermined condition. In the present embodiment, the corrected total travel distance is calculated based on the actual travel distance calculated based on the history of changes in vehicle position coordinates, and the above correction coefficient. In addition, the corrected total traveling distance can be said to be a virtual total traveling distance based on traveling in a virtual space relative to the traveling distance in real space.

  The closeness is an index indicating the degree of relationship with the character. The character information is output in response to the high and low degree of closeness. As the closeness degree is higher, character information such as a reward that the driver who is the user wants is output. Focusing on the travel distance as the degree that the user was with the radar detector and then the character, the longer the travel distance is, the higher the degree of being together, and the control between the driver and the character is good, that is, the closeness is high. Based on This is because the driver travels for a long time and a long distance with the character as the total distance travels, and the relationship becomes better. In the present invention, the closeness corresponding to the total running distance is not uniquely identified, for example, if the actual total running distance simply exceeds the set threshold, the closeness also increases by one step. The amount of change in changing the relationship based on the increase in the travel distance of the vehicle is changed. That is, the closeness is determined based on the corrected total travel distance obtained based on the above-described correction coefficient. By appropriately controlling and determining the correction coefficient, the corrected total traveling distance can be made longer or shorter than the actual total traveling distance. Details will be described later.

  The surrounding information is information about target objects around the current position of the vehicle. As information on the target object, there is information indicating the type of the target object and the distance between the current position and the target object. The type and distance of the target object are determined based on the map information stored in the database 19 and the vehicle position coordinates stored in the RAM. The driving state is information indicating the driving state of the vehicle. The driving state includes meandering operation, sudden acceleration (including speed increase during traveling and sudden start from stop), rapid deceleration, right-handed steering wheel, left-handed steering wheel, reduced concentration driving, drowsy driving, and the like. The OBD information includes fuel consumption, fuel flow rate, vehicle speed, coolant temperature, engine speed, throttle opening degree, and the like. The control unit 18 turns on an event flag when an event occurs.

  As shown in FIG. 11B, in addition to the program such as the firmware, the EEPROM also stores the corrected total traveling distance up to the last stop of the engine, the violation situation of the driver, and the like. The corrected total travel distance is stored in the RAM as described above when the engine is running when the vehicle is traveling and the radar detector 1 is operating. Then, the corrected total traveling distance at that time, which was stored in the RAM when the engine was stopped, is stored and held in the EEPROM. The violation status information is information on a violation that occurred during driving. The control unit 18 associates and stores the details of the violation, the place where the violation occurred, and the number of times.

(Function of control unit)
12 to 16 show flowcharts showing functions of the control unit 18. The control unit 18 executes the firmware stored in the EEPROM to start main processing. As shown in FIG. 12, when the main process is started, the control unit 18 determines whether an operation of turning on the power of the radar detector 1 has been detected (S11). When the operation to turn on the power is not detected (S11: NO), the process returns to S11. When an operation to turn on the power is detected, the control unit 18 starts fixed cycle processing which is interrupt processing started in a predetermined cycle (S13). With the start of the periodic process, the control unit 18 reads the corrected total traveling distance stored in the EEPROM, and stores the read corrected total traveling distance in the RAM.

(Fixed cycle processing)
When the constant cycle processing is started in S13 (see FIG. 12), the control unit 18 repeatedly performs the constant cycle processing at a constant cycle (for example, every one second). That is, the control unit 18 executes the main process and the fixed cycle process in parallel. This fixed cycle processing is as follows. As shown in FIG. 13, the control unit 18 first receives a GPS signal via the GPS receiver 13 (S31). The control unit 18 identifies the current date and time based on the date and time data included in the received GPS signal, and stores the identified current date and time in the RAM (S33). The control unit 18 acquires OBD information from the vehicle via the OBD adapter 21 and stores the acquired OBD information in the RAM (S35). Next, the control unit 18 executes a process (target position specifying process: see FIG. 14) of specifying the position of the target object existing around the vehicle (S37).

  This target position specifying process is as shown in FIG. That is, first, based on the GPS signal received from the GPS satellite via the GPS receiver 13, the control unit 18 specifies coordinate information indicating the position of the vehicle. The control unit 18 stores the specified coordinate information in the RAM as vehicle position coordinates (S51). The control unit 18 refers to the map information stored in the database 19 and determines whether there is a target object in the vicinity (for example, within 2 km from the current position of the vehicle) of the coordinate information indicating the position of the vehicle identified in S51. (S53). If there is a target object in the vicinity of the vehicle (S53: YES), the control unit 18 associates the type of the corresponding target object with the distance between the target object and the vehicle, and stores it in the RAM as surrounding information (S55).

  If the target object is not in the vicinity of the vehicle, or after performing the processing S55, the control unit 18 determines that there is a signal corresponding to microwaves in a frequency band emitted from a velocity measuring device that emits radar waves such as mobile radars. , Receive the signal via the microwave receiver 14. In addition, the control unit 18 includes control radio, car location radio, digital radio, special radio, supervisory radio, police telephone, police activity radio, wrecker radio, helitele radio, firefighting helitele radio, firefighting radio, ambulance radio, highway radio , Police radio etc. (hereinafter, these are collectively referred to as "Car location radio") scan the frequency. Then, when there is a wireless signal at the scanned frequency, the control unit 18 receives the signal via the wireless receiver 15 (S57).

  The control unit 18 determines whether a target object that emits a microwave or a wireless signal is present nearby (S59). Specifically, the control unit 18 determines whether the reception level of the received signal is equal to or higher than a predetermined value when the signal is received through the microwave receiver 14 or the wireless receiver 15. . When the reception level of the received signal is equal to or higher than a predetermined value, the control unit 18 determines that the speed measuring device that outputs the signal or a vehicle that outputs the car location radio (hereinafter referred to as a police emergency vehicle etc.) is nearby. Yes (S59: YES). The control unit 18 specifies a device (a speed measurement device or a police emergency vehicle or the like) that has output a signal based on the frequency of the signal. The control unit 18 stores information indicating the specified target object as peripheral information in the RAM (S61). As a result, the target position identification process (FIG. 13: S37) ends, and the process returns to the periodic process (FIG. 13). If the control unit 18 does not receive a signal via the microwave receiver 14 or the wireless receiver 15 or if the reception level of the received signal is less than a predetermined value, the target object that has output the signal is a vehicle It is determined that it is not in the vicinity of (S59: NO). As a result, the target position identification process (FIG. 13: S37) ends, and the process returns to the periodic process (FIG. 13).

* Calculation of Correction Total Travel Distance, etc. After the above-mentioned target position identification process (FIG. 13: S37), the control unit 18 calculates the correction total travel distance, and stores the calculated correction total travel distance in the RAM (S39) ). That is, the control unit 18 updates the storage area of the corrected total travel distance of the RAM. Specifically, based on the history of changes in vehicle position coordinates stored in RAM, control unit 18 performs (for example, 1 second) from the execution of the previous fixed cycle processing to the execution of the current fixed cycle processing. The travel distance is determined, and the current correction coefficient is determined. The control unit 18 obtains the corrected travel distance in the execution cycle (for example, one second) of the fixed cycle processing according to the following equation.

Correction travel distance = correction coefficient × travel distance

  Then, the control unit 18 adds the calculated corrected travel distance and the corrected total travel distance stored so far in the RAM to obtain a corrected total travel distance taking into account the current travel distance, and determines the obtained corrected total travel distance. Record the distance in RAM. Further, the control unit 18 stores the obtained correction coefficient in the RAM as one of the correction information.

  As shown by the equation for obtaining the corrected traveling distance described above, when the correction coefficient is 1, the actual traveling distance and the corrected traveling distance become equal (see “solid line” in FIG. 17A). Therefore, for example, the corrected travel distance obtained when actually traveling 1000 km is 1000 km. On the other hand, if the correction coefficient is larger than 1, the corrected travel distance becomes longer than the actual travel distance (see “dotted line” in FIG. 17A), and if the correction coefficient is smaller than 1 actually The corrected travel distance is shorter than the travel distance in (see “Dot-dotted line” in FIG. 17A).

The correction coefficient may be determined based on, for example, a sensor output value (acceleration) of the acceleration sensor 22. For example, the correction coefficient in the normal state in which the acceleration is set equal to or less than the threshold is set as the normal correction coefficient, and the control unit 18 sets the correction coefficient to a predetermined value smaller than the normal correction coefficient when the acceleration exceeds the threshold. Then, when the normal state continues for a fixed period, control is made to restore the original normal correction factor. Then, in the present embodiment, the small predetermined value when the acceleration exceeds the threshold is set to “0”, and the return to the normal correction coefficient is gradually returned over the predetermined period (FIG. 17B). reference). Specifically, the control unit 18 calculates the correction coefficient based on the following equation.

Correction factor = (m ^ 2 * L) / (mL + d)

Here, m is the normal correction coefficient (the value at which the asymptotic line converges)
L is the distance traveled since acceleration exceeds the threshold (actual distance traveled) Units are meters d is the distance constant
(When the engine is on: 10
After reaction by acceleration sensor: Fixed value greater than 10 eg 100)

  In the above equation, m and d are fixed values, and are stored in the correction information of the RAM. Each time the control unit 18 executes the periodic processing, that is, from the execution of the previous periodic processing to the execution of the current periodic processing based on the history of changes in vehicle position coordinates stored in the RAM every one second. The travel distance between (for example, 1 second) is determined. The control unit 18 reads the travel distance of the predetermined period stored in the storage area of the correction information of the RAM, and adds the travel distances for the current calculated above to obtain the value of L. The control unit 18 substitutes the obtained value of L and the values of m and d stored as correction information of the RAM into the above equation to calculate a correction coefficient. Further, the control unit 18 updates the travel distance of the predetermined period stored in the storage area of the correction information of the RAM to the value of L obtained this time.

  When the acceleration exceeds the threshold value, L is reset to 0, so that the correction coefficient once becomes 0, and as L increases, the correction coefficient also increases. When "mL" becomes sufficiently large compared to "d", the correction factor becomes m, that is, the normal correction factor, because the denominator d in the equation for obtaining the correction factor can be ignored.

  Further, since the value of L is stored in the storage area of the correction information of the RAM, the stored data disappears when the engine is stopped, and the value of L is also reset to 0 when the engine is turned on. Therefore, by setting the value of d to 10 when the engine is turned on, the value of L will be sufficiently larger than d immediately after the start of traveling so that the correction coefficient will immediately become m of the normal correction coefficient. There is. On the other hand, after the acceleration exceeds the threshold and the correction coefficient becomes 0 once, the value of d is increased (for example, 100) to allow time for the normal correction coefficient to be restored.

  In this embodiment, based on the output of the acceleration sensor, it is possible to individually detect sudden acceleration / deceleration and sudden steering (right sudden steering / left sudden steering). Therefore, a threshold is set for each, and the value of L is reset to 0 when the acceleration in at least one detection direction exceeds the threshold.

  Driving whose acceleration exceeds the threshold value is either rapid acceleration or rapid deceleration, or sudden steering, and not only is dangerous driving, but also makes the riding comfort worse for the character on board, and it is likely It is not good either mentally. Therefore, in the present embodiment, the correction coefficient is reduced so that the familiarity hardly increases when the acceleration exceeds the threshold, and the normal correction coefficient is not restored for a certain period. ing.

  As described above, in the present embodiment, when the setting condition (here, the threshold value of the acceleration) is not satisfied once and the correction coefficient becomes small, even if the setting condition is satisfied immediately thereafter, the condition is not returned immediately. The period was kept with a small correction coefficient. For example, in a non-preferred condition such as a dangerous operation in which the acceleration exceeds a threshold value, an accident or the like may occur if it occurs even momentarily for a short time, so it is preferable not to be in the relevant condition during the driving period. Therefore, since the driver will keep in mind driving that does not satisfy the setting condition even if it is instantaneous, etc., it is preferable because the setting condition can contribute to safe driving and the like. Furthermore, even if the setting condition is not satisfied even once, the operation does not return to the original state until a certain period of time elapses even if the operation satisfies the setting condition, which causes a penalty and a game element may appear.

  As described later, the increase in the corrected total travel distance is related to the increase in closeness. Therefore, assuming that the degree of increase in familiarity based on the increase in the actual travel distance, that is, the change amount in which closeness increases when the correction coefficient is 1, the "reference change amount" When the correction coefficient becomes smaller than 1, the amount of change in the intimacy increase with traveling becomes smaller than the reference amount of change and the elongation is low.

  If the normal correction factor is set to a value larger than 1, driving is performed so that the acceleration does not exceed the threshold, and the amount of change in familiarity accompanying traveling is larger than the amount of reference change. It is possible to maintain the closeness quickly and in a short driving distance.

  For example, the value of the normal time correction coefficient is set larger as the threshold is smaller, and conversely, the value is set smaller as the threshold is larger. In other words, if the threshold is small, the sensitivity is high, and even if the speed change is small (a relatively small acceleration), L is likely to be reset to 0 even if the threshold is exceeded. The distance traveled can be increased and the closeness can be increased. On the other hand, if the threshold is large, the sensitivity will be low, and even if there is a slight velocity change (relatively large acceleration), the correction factor will be lower than the normal correction factor over a certain period of time. Although the negative assessment control does not occur, even if the vehicle is traveling below the threshold value, the normal correction coefficient is originally small, so the growth of the corrected total traveling distance is low along with traveling. Therefore, the user may set the threshold in accordance with the driving situation of the user, the traveling road condition, and the like.

  If the setting condition (threshold value) is tightened, there is a disadvantage that a small correction coefficient value occurs for a fixed period without satisfying the setting condition due to a slight mistake in driving operation, etc., or if the setting condition is satisfied Is large, the degree and degree of goodness of the relationship rise in a short period of time, and various character information can be obtained according to the relationship. Therefore, it becomes like high risk and high return, and the game is enhanced. In addition, not only the game nature is simply increased, but driving that meets more stringent setting conditions is usually safer and more environmentally friendly, such as safe driving or eco driving, for example. As it is often the case, it is preferable to the traffic environment.

  In this setting, for example, information is stored in the database 19 in which combinations of threshold values in respective detection directions respectively corresponding to sensitivity of a plurality of levels are associated with correction coefficients of the levels. For example, for the standard level, a threshold is set for each acceleration sensor output that detects sudden acceleration / deceleration, right sudden steering or left sudden steering, and 1 is associated as a correction coefficient. Then, for a level that is more sensitive than the standard level, a threshold smaller than the threshold associated with the standard level is set, while the correction coefficient is set to a value larger than one. Conversely, for levels less sensitive than the standard level, a threshold larger than the threshold associated with the standard level is used, while the correction coefficient is a value smaller than one. Prepare one or more sensitive levels and insensitive levels. The control unit 18 reads out a predetermined setting screen from the database 19 and displays the screen on the display unit 5 and recognizes and sets the level designated by the driver based on the signal from the touch panel 6.

* Identification of closeness The control unit 18 specifies closeness based on the corrected total traveling distance (S40). The closeness is a parameter that is determined according to the corrected total travel distance. The control unit 18 assumes that the intimacy of the character with respect to the driver increases with an increase in the corrected total travel distance of the vehicle, and expresses the degree of intimacy as the intimacy degree. Specifically, the closeness is determined as follows. If the total travel distance is less than the first reference distance (for example, 100 km) from when the radar detector 1 is activated for the first time, the intimacy becomes zero. When the total travel distance of the vehicle in the character mode is set to 100 km or more and less than 1000 km, the closeness degree is 1. When the total travel distance of the vehicle in the character mode is set to 1000 km or more and less than 2000 km, the closeness is 2. When the total travel distance of the vehicle is 2000 km or more with the character mode set, the closeness is 3. The control unit 18 stores the obtained closeness in the RAM.

  The closeness is an index indicating the degree of the relationship with the character, and the better the relationship, the larger the value. In the present embodiment, the closeness level is raised to four levels, such as 0 → 1 → 2 → 3. The closeness is a condition for determining the character information to be output via the output device as described later. The better the relationship is, that is, the closer the value is to the value, the character information to be output will fly into variation, and the content is kind of something that makes the user friendly and makes the user happy. .

  As control to make the relationship better, that is, information to increase closeness, travel distance is the basis, and in principle, closeness is set to be higher as travel distance is longer. For example, assuming that the character has personality and emotion, the longer the travel distance, the better the driver's relationship, the longer the drive distance with the character. Therefore, for example, if the mechanism is such that the relationship becomes better as the user travels in safe driving, the user is more likely to maintain the relationship with the character with a good song, and the degree of the condition is further enhanced. In addition, they will try to drive safely safely.

(Specification of driving situation etc.)
Next, the control unit 18 executes a process (a driving state specifying process, see FIG. 15) for specifying driving information of the vehicle (S41). As shown in FIG. 15, the control unit 18 acquires the acceleration detected by the acceleration sensor and the vehicle speed among the OBD information stored in the RAM (S71). Next, the control unit 18 determines whether the vehicle is in a predetermined driving state based on the acquired acceleration and vehicle speed (S73). Specifically, the control unit 18 performs (a) meandering operation, (b) sudden deceleration, (c) sudden acceleration, (d) right sudden steering, (e) left sudden steering, (f) concentration reduction operation, (G) It is determined based on the acceleration and the vehicle speed whether the vehicle is being driven in any of the drowsy driving states. The judgment method is as follows.

  The number of occurrences of each state where the acceleration in the forward direction of the vehicle is 0.3 G or more, the acceleration in the backward direction of the vehicle is 0.15 G or more, and the acceleration in the lateral direction of the vehicle is 0.45 G or more Is counted, and the control unit 18 determines that (a) meandering operation is being performed when the condition that the total is generated 15 times or more in 15 minutes is satisfied. In addition, when the forward acceleration of the vehicle becomes 0.3 G or more (b), the control unit 18 determines that the rapid deceleration has been performed. When the acceleration in the rearward direction of the vehicle becomes 1.15 G or more (c), the control unit 18 determines that the rapid acceleration has been performed. When the leftward acceleration of the vehicle reaches 0.45 G or more (d), the control unit 18 determines that the sudden right steering has been performed. When the acceleration in the right direction of the vehicle reaches 0.45 G or more (e), the control unit 18 determines that the sudden left steering has been performed. When the vehicle speed is 55 km / h or more and the change width of the vehicle speed is 5 km / h or more and less than 10 km / h continuously for a predetermined time or more, the controller 18 performs (f) concentration reduction operation. I judge that I am When the vehicle speed is 55 km / h or more and the change width of the vehicle speed is 10 km / h or more, the control unit 18 determines that (g) drowsy driving is being performed. As described above, the control unit can determine the driving state of the vehicle based on the acceleration applied to the vehicle and the vehicle speed.

  The controller 18 corresponds to any of the above, and when it is determined that the vehicle is being driven in the predetermined driving state (S73: YES), stores the information indicating the corresponding driving state in the RAM as the driving state S75). Then, the operation state identification process ends, and the process returns to the periodic process. On the other hand, when the operation state does not correspond to any of the above (S73: NO), the control portion 18 ends the operation state identification process, and the process returns to the periodic process.

  As shown in FIG. 13, after the end of the operation state identification process (S39), the control unit 18 stores peripheral information in the RAM in S55 (see FIG. 14) and S61 (see FIG. 14), or It is determined whether the operating state is stored in the RAM in accordance with FIG. If any one of them is stored in the RAM, the control unit 18 determines that an event for notifying the driver has occurred (S43: YES). The control unit 18 turns on the event flag (S45). The periodic processing ends. On the other hand, when neither the surrounding information nor the driving state is stored in the RAM (S43: NO), an event for notifying the driver has not occurred, so the control unit 18 turns off the event flag. (S47). The periodic processing ends.

  As shown in FIG. 12, after activating the periodic processing (see FIG. 13) in S13, the control unit 18 refers to the setting information stored in the database and determines the set display mode (S15). When a display mode other than the MAP display mode-character mode is set as the display mode (S15: NO), the control unit 18 reads out the information corresponding to the set display mode from the output information of the database 19 and outputs it Output from Thereby, the control unit 18 performs a known normal operation operation (alarm notification and the like) (S21). The processing proceeds to step S23. On the other hand, when the MAP-character mode is set as the display mode (S15: YES), the control unit 18 executes a process (character mode process, FIG. 16) of notifying the driver of predetermined information via the character. (S19).

  The character mode processing will be described with reference to FIG. The control unit 18 reads logo information stored in the database 19, and displays a logo screen on which the logo information is drawn on the display unit 5 (S81). By displaying the logo screen in this manner, the user can confirm that the MAP-character mode is set.

  The control unit 18 determines whether the current date and time etc. have already been specified in the periodic processing started in S13 (see FIG. 12), and the information is stored in the RAM (S85). In the fixed cycle processing, it is not possible to receive the GPS signal immediately after activation depending on the radio wave environment to specify the current date and time, position information of the vehicle, traveling distance, etc. by receiving the GPS signal which is a radio signal from GPS satellites. is there. Therefore, the time required to specify the current date and time may not be constant, and may take time. If the current date and time etc. are not stored in the RAM, it means that the current date etc. has not been specified yet (S 83: NO).

  In this case, the control unit 18 displays the wallpaper screen 73 on which the character 104 is lying down on the display unit 5 as shown in FIG. 18 (S85). If the current date and time etc. are not specified, it is not possible to calculate the traveling distance and thus the corrected total traveling distance and specify the closeness, so that the wallpaper screen 73 is displayed to notify that the state is unconfirmed. The processing returns to S83. Thus, the control unit 18 keeps displaying the wallpaper screen 73 until the current date and time etc. are specified. With the current date and time etc., there is a history of the position information of the vehicle other than the current date and time, etc., but when the current date and time is stored in the RAM, the GPS signal can be received. It may be based.

  When the current date and time, the position information of the vehicle, etc. are specified in the fixed cycle processing, and the information is stored in the RAM (S83: YES), the control unit 18 reads the still image information stored in the database 19 and displays it. Is displayed on the screen (S86). As a result, for example, as shown in FIG. 19, a still screen 72 showing the character 104 wearing a clear dress is displayed on the display unit 5. The still screen information includes a total of 12 still screens which are different for each month. Each stationary screen reflects the scene of the season. When reading out the still screen, the control unit 18 extracts the present month from the current date and time information, selects the still screen of the month corresponding to the extracted present month from the still screen information stored in the database 19, and displays Display on 5

  Thus, the radar detector 1 suppresses the driver from being bored with the still screen by switching the still screen displayed on the display unit 5 according to the date and time. The radar detector 1 also gives the driver a feeling of wanting to see a new static screen. Here, for example, the control unit 18 may perform control so as not to display a new still screen on the display unit 5 when the driver performs dangerous driving or the like. As a result, the driver tries to drive safely in order to display a new still image on the display unit 5. Thus, the radar detector 1 can effectively guide the driver to a safe driving.

  After a predetermined time has elapsed since the still screen was displayed on the display unit 5, the control unit 18 reads the startup screen included in the startup information stored in the database 19 and displays it on the display unit 5 (S87). Further, the control unit 18 reads out the start sound included in the start information and outputs the sound from the speaker 16 (S87).

  The boot information will be described in detail with reference to FIGS. 20 and 21. The activation information is information output to the output device at the time of activation in the MAP display mode-character mode. As shown in FIG. 20, the activation information includes information for displaying an image of the character on the display unit 5 (hereinafter referred to as a character image), and information for outputting the voice of the character from the speaker 16 (hereinafter referred to as , Character voice) is included. Character images and character voices are familiarity (0 to 3) and time zones (0:00 to 5:00, 5:00 to 7:00, 7:00 to 10:00, 10:00 to 17:00, It is classified into 17: 00-22: 00 and 22: 00-0: 00). The time zone indicates the time when the power of the radar detector 1 is turned on. A plurality of character images and character voices are prepared for each intimacy degree and time zone so that the character can communicate with the driver in various expression modes.

  FIG. 21 shows the character voice corresponding to the time zone 7:00 to 10:00 in detail. If the intimacy stored in the RAM is 1, "Good morning. How are you doing?" "Now, please do your best at work. I will do my best." "Good morning. Safe driving today "Please, please." It is a slightly different character voice. The expression mode of the character to the driver is the first meeting mode. On the other hand, if the intimacy is 2, "Good morning. How are you doing?" "Don't just enjoy things every day, but do your best." "Oh! Do you drive with caution today?" In comparison with the case where the intimacy degree is 1, it is an intimate character voice. The expression mode of the character to the driver is a normal friend mode. Furthermore, if the intimacy is 3, "Good morning! Hey, I've been waiting since I got up, I guess." "Way! I can stay with you today as well.-I'm glad" "Good morning! Fashionable today. It's a more intimate character voice compared to the case where the intimacy is 1 and 2 like "new clothes, I want ~". The expression mode of the character with respect to the driver is a Tally-speaking aspect.

  Thus, the radar detector 1 enhances the intimacy of the character with respect to the driver according to the intimacy by outputting a more intimate character voice as the intimacy increases. When the driver feels that the intimacy of the character gradually increases, the familiarity with the character gradually increases and the character is strongly empathetic.

  Also, although not shown, character voices in the time zone of 5:00 to 7:00 are compared for each closeness. If the closeness is 1, "Good morning ~ ~ ~-Excuse me." "Good morning. I will do my best to alert again today." "I'm getting up early. It has become. If the intimacy is 2, it is a character voice like the character voice of "Ah? Is it already morning?" "Still no good! Even sleepy." Furthermore, if the intimacy degree is 3, "Good morning ~ Good morning ~, Good morning." "Good morning ~ Still sleepy ~. One minute." "Good morning, I have to keep alert even today. For you It is a character voice like "." By listening to the sleepy voice of the character, the driver feels as if the character is a real creature. Furthermore, the driver has a feeling that he / she apologizes for the character. The radar detector 1 further enhances the degree of empathy for the driver's character by impressing the user with such emotions.

  In the above description, an example in which the character voice is switched at each activation time has been described. However, the character image is also switched at each activation time. For example, in the time zone 0:00 to 5:00, the character image of the expression aspect in which the character is sleeping in the bed is associated. The driver has an intimate feeling for the character by watching the character going to bed. The radar detector 1 further enhances the degree of empathy for the character of the driver by impressing the driver with such emotions.

  As described above, the radar detector 1 switches and outputs the character voice for each activation time zone as if the character were a real creature. This causes the driver to feel as though the character is real. Thus, the radar detector 1 can increase the degree of empathy for the driver's character. In addition, the output character information has a variation like as familiarity increases, and also has content like a kind of reward that makes the driver friendly and happy for the driver. Therefore, the driver is strongly motivated to operate or drive to maintain a good relationship or to obtain a better relationship so as to receive rewards. Therefore, it can be expected that the driver performs driving such that the intimacy is high. That is, in the present embodiment, the increase in closeness is not only a simple increase in the travel distance, but the amount of change with respect to the predetermined travel distance changes based on information on the travel of the vehicle, for example, whether the acceleration exceeds a threshold or not. When control is performed and acceleration exceeding the set threshold is applied to the vehicle, control is performed such that the extension of the corrected total travel distance, which determines closeness over a certain period, decreases. Therefore, the driver tries to travel so that the acceleration detected by the acceleration sensor 22 is equal to or less than the set threshold. Therefore, the radar detector 1 of the present system contributes to safe driving.

  Furthermore, in order to increase the closeness, that is, the corrected total travel distance, it is not sufficient to simply extend the travel distance, and information on travel of the vehicle (acceleration in the present embodiment) is also added. For example, if the correction coefficient does not become 0 even once during driving, for example, while the vehicle is driving, it is preferable because the corrected total traveling distance can be earned and a sense of clearing the mission can be obtained. The clearing of such a mission is not just a game in a virtual space, but a game of a new feeling that occurs with actual driving. And, even if the actual driving of the vehicle is given game characteristics, clear of the mission is safe driving not to change speed (increase / decrease speed) and sudden direction change such that the acceleration value becomes below the threshold. As it is necessary, there is no problem with social norms. The same applies to the output of character information based on the closeness shown below.

  In the activation information of FIG. 20, character voice is not associated with familiarity: 0. When the closeness is 0, the radar detector 1 displays a character image on the display unit 5 and does not output character sound from the speaker 16. In this case, the driver recognizes not only the character image but also the character voice, and inspires an expectation that the intimate communication with the character should be started early. The radar detector 1 enhances the degree of empathy for the driver's character by utilizing such driver's psychology.

  As shown in FIG. 16, after outputting the activation information (S87), the control unit 18 reads the character information in the standby information of the database 19 and outputs it from the output device (S91). The character information is information output from the output device when the radar detector 1 operating in the MAP display mode-character mode is in the standby state. Details of the character information will be described with reference to FIGS. 22 and 23. As shown in FIG. 22, the character information includes a character image and a character voice. Character images and character voices are classified according to familiarity. In FIG. 22, “closeness 1-3” indicates that different character images and character voices are associated with each closeness.

  A plurality of character images and character voices are prepared for each expression mode so that the character can communicate with the driver in various expression modes. Specifically, the character information includes character images and character voices corresponding to the respective expression modes of (1) blink & mouth, (2) blink only, (3) walk, and (4) stretch. ing. For example, when a character image corresponding to (1) blink & mouth pattern is displayed on the display unit 5, the character blinks and moves the mouth as if it is singing something. Further, for example, when a character image corresponding to a walk is displayed on the display unit 5, the character walks freely in the display area of the display unit 5. Further, for example, when the character image corresponding to (4) stretch is displayed on the display unit 5, the character stretches. In addition, character voice corresponding to each expression mode is output from the speaker 16.

  FIG. 23 shows (1) the character voice corresponding to the blink and mouth mark in detail. If the intimacy is one, like "Do you like driving? I hate your driving." "Ah, thank you for coming me with your car, Thank you!" Familiar character voices are associated. On the other hand, if the intimacy is 2, "I like you, I liked it? I also liked you, I liked it!" "When I'm driving, I'm pretty serious." Thus, more intimate character speech is associated as compared to the case where the intimacy degree is 1. Furthermore, if the intimacy is 3, "I'm happy every day because you talk to me!" "Ah, I really want to talk more. I want to know more about you." More intimate character voices are associated as compared with the case of 1 and 2. When character voice is output from the speaker 16, one of the plurality of character voices associated with the familiarities: 1, 2, and 3 is randomly selected and output. Therefore, different character voices are output from the speaker 16 each time even in the situation where the closeness is the same.

  Thus, the radar detector 1 enhances the intimacy of the character with respect to the driver according to the intimacy by outputting a more intimate character voice as the intimacy increases. When the driver feels that the intimacy of the character with respect to him gradually increases, the familiarity with the character gradually increases and the character is strongly empathetic.

  Further, the radar detector 1 constantly displays the character on the display unit 5 and outputs character voice from the speaker 16 so that the character speaks to the driver even in the standby state where no event occurs. In this way, the driving support system 4 makes the driver feel as if the character were a real creature, and as if he was always by his side. Since the driver has an affinity for the character, the degree of empathy for the character of the driver is further enhanced.

  Furthermore, the radar detector 1 prepares a plurality of character images and character voices, randomly selects these and outputs them from an output device. This prevents the communication by the character from becoming monotonous and prevents the driver from getting bored with the communication with the character.

  In FIG. 22, only the character image is associated with the closeness: 0, and the character voice is not associated. Therefore, when the intimacy degree is 0, the character image is displayed on the display unit 5 and the character voice is not output from the speaker 16. Since the driver can not hear the character voice in a state where the intimacy is small, he / she has an expectation that he / she wants to recognize not only the image of the character but also the voice. The radar detector 1 further enhances the degree of empathy for the driver's character by utilizing such driver's psychology.

  As shown in FIG. 16, after the control unit 18 outputs the character information corresponding to the standby state from the output device in S91, is the timing at which the control unit 18 outputs the character information (see FIG. 24 or later)? (S93). Character information is information output to an output device when an event occurs in the radar 1 operating in the MAP display mode-character mode. Details of the determination method and the information to be output will be described later. When it is determined that it is the timing to output the character information (S93: YES), the control unit 18 outputs the character information from the output device (S95), and the process proceeds to S97. On the other hand, when the control unit 18 determines that it is not the timing to output the character information (S93: NO), the process proceeds to S97.

  The method of determining whether or not the character information in the event information is to be output, and the character information to be output are as follows. FIG. 24 shows details of character information in event information. The character information includes a character image and a character voice. A plurality of character images and character voices are prepared for each expression mode. In FIG. 24, (1) go to bed, (2) get up, (3) sleep talk, (4) caution for overspeed, (5) car sickness, (6) sudden deceleration, (7) sudden drop Acceleration, (8) Right-handed steering wheel, (9) Left-handed steering wheel, (10) Anger and disappear when the degree passes, (11) Anger settles and returns, (12) Nap, (13) Wakes up, (14) Deterioration in concentration, (15) drowsy driving, (16) Orbis, control, interrogation alarm, (17) radar, car location reception alarm, and (18) other target objects Character images and character voices corresponding to the target object are familiarity levels: 1 -3. Similar to the character information in the standby information shown in FIG. 22, the character voice corresponding to the familiarity: 0 is not included in the character information in this event information. Therefore, when the closeness is 0, the control unit 18 outputs the character image from the output device, and does not output the character voice from the speaker 16.

  For example, the character information corresponding to “(1) go to bed” is information to be output when the radar detector 1 is activated between 22:00 and 0:00. When the character image is displayed on the display unit 5, the character goes to bed at a timing when one minute has passed after activation of the radar detector 1. The control unit 18 uses a voice to inform the driver of the bedtime as the information that indicates this bedtime ("Today was fun-take drive tomorrow as well." "I will sleep. You also sleep properly. "Good night" etc. is selected according to the intimacy degree, and is output from the speaker 16 as a character voice. In addition, after sleeping, the control unit 18 periodically outputs the character's sleep from the speaker 16 as character voice.

  For example, the character information corresponding to “(2) wake up” is information to be output when the radar detector 1 is activated between 5:00 and 7:00. When the character image is displayed on the display unit 5, the character wakes up at a timing when one minute has passed since the activation of the radar detector 1. The control unit 18 provides a voice to inform the driver of getting up as information to indicate the time of getting up ("Good morning. Alarm restart and Mars" "Good morning. I can be together today! Nice!" Etc.) Are selected according to the intimacy degree, and output from the speaker 16 as character voice.

  For example, the character information corresponding to “(3) sleeping sleeping” is information that is randomly output in a cycle of 5 minutes in 10 minutes to 30 minutes while the character is sleeping. When the character image is displayed on the display unit 5, the control unit 18 performs an animation in which the character moves the mouth as information indicating the sleeping word in bedtime. In addition, the control unit 18 selects a sleeping word ("You look like a star." "Re, please fill it with a regular tank, etc.", etc.) according to the intimacy, and at the timing when the character moves the mouth, It outputs from the speaker 16 as character voice.

  As described above, in the present system, character information is output in an expression manner as if the character is a real creature. The driver will feel as though the character is real. Thus, the system can increase the degree of empathy for the driver's character.

  For example, the character information corresponding to “(4) caution of over speed” is information to be output when the vehicle speed exceeds the speed limit. The control unit 18 specifies the vehicle speed based on the OBD information stored in the RAM, and determines the speed limit based on the vehicle position coordinates stored in the RAM and the map information stored in the database. The speed limit is the speed limit of the road currently being traveled or the speed limit of the installation position of the speed measurement device present in the vicinity. The control unit 18 compares the vehicle speed with a value obtained by adding a predetermined traveling speed (for example, 10 km / h) to the determined speed limit, and outputs character information of overspeed caution when the vehicle speed is faster. When the character image is displayed on the display unit 5 as the information indicating the caution of the excessive speed, for example, the control unit 18 notifies the driver of the current vehicle speed and the speed limit to decelerate the character. Output an animation that encourages Moreover, the control unit 18 responds to the closeness according to the intimacy, such as a voice ("Hey ~ Do not speed out? Dangerous ~" "This person will hate the person who overspeeds!" Etc.) notifying the speed excess And select and output from the speaker 16 as character voice. This allows the driver to easily recognize that the traveling speed of the vehicle exceeds the speed limit. Since the degree of the driver's empathy with respect to the character is in a strong state, the driver pays attention to the safe driving by decelerating in response to the notification from the character.

  For example, the character information corresponding to "(5) vehicle sickness" is output when the event flag stored in the RAM is ON and information indicating the serpentine driving is stored as the driving state. . In such a case, there is a high possibility that the car is traveling on a curved road.

  When the character image is displayed on the display unit 5, the control unit 18 outputs an animation in which the character behaves as if he or she got sick and got sick. In addition, the control unit 18 is a parent of the character's painful voice ("Hmm, I feel a little sick, I'm sorry," "I got drunk because I already drive like that. Huh.", Etc.) as a parent. It is selected according to the density and is output from the speaker 16 as character voice. As a result, the driver feels sorry for the character's car sickness, and keeps in mind the polite driving with reduced speed. Thus, the system can urge the driver to drive with care.

  For example, in the character information corresponding to “(6) sudden deceleration, (7) sudden acceleration, (8) right-handed steering wheel, (9) left-handed steering wheel”, the event flag stored in the RAM is ON, and driving The state is information output when information indicating rapid deceleration, rapid acceleration, right-handed steering, and left-handed steering is stored. This is because when the driver drives by such a driving method, the possibility of causing a traffic accident is high. When the character image is displayed on the display unit 5, the control unit 18 outputs an animation that breaks the balance so that the character is in the direction of the detected acceleration. In addition, the voice to notify the driving method (sudden deceleration: "Cha! I was going to fall. Are you angry after the next?" "Do you look ahead? Are you looking forward to it?" Right, right curve and left curve etc., etc. "Huh, I hit the head! I saw it!" : "I'm going to handle the wheel a little more slowly-I see the eyes turn" "I did not look forward to it properly? I thought it would fall down." "I can't believe a little! It selects according to it and outputs from the speaker 16 as character voice. With these, the driver notices that he is driving wildly and dangerously, and tries to drive carefully. By giving a warning in this manner, the present system can prevent the occurrence of a traffic accident.

  For example, the character information corresponding to “(16) Orbis, control, check alarm” has the event flag stored in the RAM turned on, and the radar type Orbis, the H system, the LH system, and the loop coil In a case where information indicating the name Orvis is stored in the RAM as peripheral information, and information indicating the distance between the Orbis and the vehicle is a predetermined distance (for example, 2100 m, 1100 m, 600 m) Output to Alternatively, it is output when the event flag 38 stored in the RAM is turned on and information indicating a control or a check is stored as peripheral information.

  For example, in the character information corresponding to “(17) Radar, Car location reception alarm”, the event flag stored in the RAM is ON, and the information indicating the speed measuring device or the police emergency vehicle is used as the peripheral information in the RAM. Output when stored.

  A character image corresponding to the “(16) Orvis, control, check alarm” or “(17) radar, car lock reception alarm” is displayed on the display unit 16 as follows. As shown in FIGS. 25 and 26, first, the clothes of the character 104 change from white (FIG. 25) to black (FIG. 26). This change means that the character 104 has been transformed. In addition, it is preferable to change the clothes of the character before and after transformation and the animation operation according to the priority.

  The transformed character 104 is superimposed and displayed on the display screen of the map 100 in which the peripheral target objects 105 are shown as shown in FIG. 27, and as shown in FIG. 28, Orvis, tightening, checking, speed measuring device, and The driver is provided with information 74 indicating any of the police emergency vehicles and the distance 75 between the vehicles. In addition, voice for notifying indication contents to driver ("emergency situation, radar Orbis discovery to 2000 meters ahead." "Distance approached to 1000 meters! Radar type Orbis yo" "It is remaining 500 meters ..., photograph photography And so on are selected according to the intimacy, and output from the speaker 16 as character voice.

  As described above, the radar detector 1 as the driving support system can recognize that the target object to be monitored for traffic is near the vehicle by receiving a radio signal transmitted from the target object. Devices for monitoring traffic are often installed at places where traffic accidents are likely to occur or where accidents have occurred in the past. Therefore, the radar detector 1 makes the driver aware of a location prone to a traffic accident by notifying the driver that the target object for monitoring the traffic is near the vehicle, and particularly safe driving in such a location. Can encourage people to

  Also, the driver can easily and clearly recognize at a glance that the distance between the object to be monitored for traffic and the vehicle is approaching by changing the clothes of the character 104. The driver can accurately recognize in advance the place where there is a high risk of a traffic accident, and can drive while keeping in mind the traffic safety.

In addition, since the driver is notified by the character voice that the distance between the object to be monitored for traffic and the vehicle is approaching, the radar can be used even when the driver is not looking at the display unit 5. The detector 1 can allow the driver to surely recognize that the vehicle is approaching the Orvis or the like.
In addition, although specific description is abbreviate | omitted, the output of the character information according to familiarity is performed also about another expression aspect.

  As shown in FIG. 16, the control unit 18 determines whether the setting operation to the radar detector 1 by the driver has been detected (S 97). When the control unit 18 detects that the driver has touched the display unit 5 in the standby state via the touch panel 6, the control unit 18 determines that the driver has performed the setting operation (S97: YES), the control unit 18 The setting screen is displayed on the display unit 5 based on the setting screen information stored in the database 19. Further, the control unit 18 sequentially switches the setting screen displayed on the display unit 5 according to the content of the setting operation by the driver, and sets the setting information by storing the setting information set by the setting operation in the database 19. (S99). The control unit 18 executes the processing based on the setting information, whereby the radar detector 1 operates as set by the driver. The processing proceeds to step S101. On the other hand, when the driver does not detect the setting operation (S97: NO), the process proceeds to S101.

  The control unit 18 determines whether an operation to turn off the power of the radar detector 1 has been detected (S101). When the control unit 18 detects an operation to turn off the power (S101: YES), the character mode process is ended, and the process returns to the main process (FIG. 12). On the other hand, when the control unit 18 does not detect an operation to turn off the power (S101: NO), the process returns to S91.

(Modified example with indicator)
FIG. 29 is an example of a display screen showing a modified example of the present invention. In this modification, a display area for displaying the current correction coefficient is provided. That is, as shown in FIG. 29A, the correction coefficient display area 81 is provided on the left side of the main area where the map 100 and the character 104 are displayed. The correction coefficient display area 81 is an indicator whose light emitting area is expanded and contracted in the vertical direction. In the illustrated indicator, the approximate center position in the vertical direction of the correction coefficient display area 81 is set to “0”, and is extended upward as the value of the correction coefficient is increased. The maximum value is 4 here. Further, as described in another modified example to be described later, when the correction coefficient takes a negative value, the light emission area of the indicator has a display mode in which the correction coefficient value extends downward from the center position of 0. That is, the indicator takes an aspect as shown in a schematic diagram as shown in FIG.

  In addition, especially when the correction coefficient can be set to a negative value, for example, the length of the light emitting area is the same for both “1” and “−1”, and the length is short, and the center in the vertical direction Because it is located near, it is difficult to understand which value at a glance. In particular, the driver while driving can not watch the display unit 5 for a long time, and it is necessary to check the display contents of the map 100 and the character 104 in a short time, and the correction coefficient display area 81 is displayed. The narrow area itself makes it even more difficult to recognize the current correction factor.

  Therefore, the light emission color is made different between positive and negative. For example, when the correction coefficient is a positive value, the display color is displayed in a cold color such as blue or light blue, and when the correction coefficient is a negative value, the display color is displayed in a warm color such as red or pink. By doing this, even if a short light emitting area is displayed near the center in the vertical direction, the driver is negative whether the current correction coefficient is positive and reasonable or not. You can intuitively understand if it is very bad. In addition, red means "stop" in traffic lights, and traffic signs often mean ban, while "blue" means "advance" in traffic lights and traffic signs have no meaning in particular. The driver who is aware of can understand that reflectively red is not desirable.

  The control unit 18 operates as follows in order to execute the notification function of the correction coefficient using the indicator. The control unit 18 periodically reads the correction coefficient stored in the RAM, and displays an indicator such that the light emission area of a predetermined color is obtained up to a level corresponding to the value of the read correction coefficient. In the example of FIG. 29 (a), the portion of the light emitting area of the indicator is displayed in blue.

  The timing and period of this readout is preferably short (for example, 1 second). This is because the influence of the current driving situation on the correction factor can be understood. For example, if the indicator maintains a certain length in the positive direction, it can be confirmed that the current driving is being performed correctly. When the light emitting area of the indicator disappears when the driver steps on the accelerator pedal or the brake pedal or turns the steering wheel due to turning or turning, the driver exceeds the threshold and the correction factor becomes 0. It is possible to know that, from the immediately preceding driving situation, it is also known which action the correction coefficient has become 0. Therefore, it is possible to understand your driving habits (it is easy to start quickly / to apply a quick brake / to handle a sharp steering wheel etc.), and in particular to reflect on what kind of driving operation should be taken. Measures can be taken to operate without reduction. Further, once the correction coefficient becomes 0, as shown in FIG. 17B, the correction coefficient gradually rises and returns to the normal correction coefficient. By updating the display of the indicator in a short period, it can be seen that the light emission area of the indicator gradually expands and gradually returns toward the normal correction coefficient. Therefore, it is preferable for the driver to be happy to confirm such a condition and to continue driving with caution so that the acceleration does not exceed the threshold.

  On the other hand, when the average over a long period is taken, it is difficult to achieve the above effect. That is, even if the correction coefficient drops to 0, the condition does not appear immediately, and the driver can not understand which driving operation caused the acceleration to exceed the threshold or may be buried by the high correction coefficient before that. It may be difficult to recognize that the correction factor has not fallen to 0 and safe driving has not been performed. Furthermore, even if the correction coefficient has fallen once, it may not be recognized when the indicator display is updated the next time, as it has returned to its original state and is gradually returning.

  Moreover, although it is an update period of this indicator, it is good to match with the period of a fixed period process. This is because the correction coefficient is updated each time the fixed cycle processing is performed to affect the corrected traveling distance, so that the present correction coefficient can be known. The display process of the indicator may be performed in parallel with the periodic process or may be performed as the periodic process.

  In the embodiment described above, the closeness is obtained based on the corrected total traveled distance obtained by correcting the actual traveled distance based on the correction coefficient, and character information corresponding to the closeness is output. According to the embodiment described above, the driver can efficiently extend the corrected total traveling distance and increase the closeness by performing the driving such that the acceleration does not exceed the threshold, while the acceleration exceeds the threshold. In this case, the correction coefficient decreases for a certain period, and the rate of increase in the corrected total travel distance accompanying traveling decreases. However, the driver can not accurately know whether the correction factor maintains a high value in the current driving, or whether the acceleration exceeds the threshold and is a low correction factor.

  Therefore, the present correction factor is notified using the correction factor display area 81 (for example, an indicator) as in this modification, so that the driver can know the present correction factor, and the current driving method, It is immediately understood how the amount of change is changed and reflected depending on the driving condition. Therefore, the driver can know, for example, what kind of driving operation makes the correction coefficient smaller or larger. As a result, the driver can take a driving operation such that the correction factor does not decrease or increase. In addition, by informing the driver of the current correction factor, it is possible to make the driver motivated to maintain the state as it is or to improve the correction factor.

  Further, in this modification, the present correction coefficient is notified using an indicator, but the present invention is not limited to this, for example, it may be expressed by a numerical value or may be changed gradually like gradation. It may be expressed indirectly by a method.

  Furthermore, notification of the current correction coefficient may be made not by the correction coefficient itself but by changing the appearance of the character according to the correction coefficient. For example, although the specific illustration is omitted, it is preferable to change the facial expression of the character. As an example of this change, "smiling" → "normal" → "looks sad" → "must be", etc., and the degree of smile may be further divided into multiple stages. In addition, if it is difficult to understand if it is only facial expression, it is good to add animation operation. In either case, the character information corresponding to the one with the larger correction coefficient may be content that is more familiar to the user and is a kind of reward that makes the user happy. The notification function of the correction coefficient using the appearance of the character may be performed alone, or may be performed in combination with another notification such as an indicator.

(Modified example with acceleration change setting function)
In the embodiment described above, the value of the normal correction coefficient is set to be larger as the threshold is smaller and to be smaller as the threshold is larger. This setting is made to select a combination of predetermined threshold values and a normal correction coefficient by designating "sensitivity-standard-insensitivity". On the other hand, in this modification, thresholds (detection sensitivities) can be individually set for each of four accelerations for detecting sudden acceleration / deceleration, right abrupt steering, and left abrupt steering.

  The specific setting is performed using the internal data as shown in FIG. 30 (FIG. 30 (a), (b)) and the input screen (FIG. 30 (c)) which is an interface for inputting setting conditions as shown in FIG. That is, the table shown in FIG. 30 associates the sensitivity shown in FIG. 30 (a) as internal data with each acceleration threshold for the combination of four detection targets of rapid acceleration / deceleration, right abrupt steering, and left abrupt steering. There is a table in which the sensitivity shown in (b) is associated with the asymptotic value for each combination of four detection targets.In this example, the rapid acceleration and rapid deceleration are divided into six sensitivity levels, and the left and right sharp steering wheel Are divided into four sensitivity levels, and the database 19 stores screen information of a matrix structure shown in FIG.

  For example, when detecting that the driver touches the display unit 5 in the standby state, the control unit 18 first displays a main menu screen (not shown) on the display unit 5. When the control unit 18 detects that the acceleration sensor sensitivity selection button provided on the main menu screen is touched, the control unit 18 reads the setting screen shown in FIG. 30C and displays the setting screen on the display unit 5. The button area of the current setting condition is displayed in a color different from that of the other button areas. In the illustrated example, the sensitivity of the rapid acceleration and the rapid deceleration is 4 and the sensitivity of the right sharp steering wheel and the left sudden steering wheel is set to 3.

  Each button area specified by the sensitivity and the four detection targets in this setting screen is set as an area corresponding to the acceleration sensor threshold (FIG. 30A) and the asymptotic value (FIG. 30B). Associated with a number. For example, taking the current selection state as an example, the sensitivity 4 of rapid acceleration is associated with the threshold value of the acceleration sensor being 0.4 and the asymptotic value being 0.2. Similarly, the sensitivity 4 of the rapid deceleration is associated with an asymptotic value of 0.2 with a threshold of 0.4 for the acceleration sensor, and the sensitivity 3 with an acceleration sensor for 0.5 with an acceleration sensor of 0.5 Line value 0.3 is associated. Under this setting condition, the correction coefficient becomes 0 when either acceleration in the front-rear direction exceeds the threshold (0.4), and acceleration in the left-right direction exceeds either the threshold (0.5). The correction factor is zero. In other words, if all the accelerations in the four directions do not exceed the corresponding threshold value, the set normal correction factor is maintained. The normal time correction factor is the sum of each asymptotic value. That is, in this example, the correction coefficient for normal condition is 1 from 0.2 + 0.2 + 0.3 + 0.3. Therefore, under this setting condition, when the acceleration is equal to or less than the threshold value, the travel distance and the correction total travel distance become the same increment.

  On the other hand, in the present modification, since the sensitivity can be set individually for four detection targets, for example, when it is detected that the button area of insensitive (for example, 2) the sensitivity of rapid acceleration is touched, the control unit 18 30 (a) and the asymptotic value data shown in FIG. 30 (b) are accessed, and the threshold (0.5) of the acceleration sensor associated with the sensitivity 2 of the rapid acceleration touched is asymptotically The line value (0.1) is acquired and set in the corresponding area of the RAM. Then, since the acceleration threshold for rapid acceleration is changed from 0.4 to 0.5, the probability of exceeding the threshold decreases, and the probability that the correction coefficient is reset to 0 decreases. On the other hand, under this setting condition, the correction coefficient for normal condition is 0.9, so even if the operation does not exceed the threshold value, the correction travel distance becomes shorter than the travel distance, and the distance does not extend. On the other hand, when the sensitivity of the right-handed steering wheel is raised to 4 from the state shown in FIG. 30, the control unit 18 accesses internal data in the same manner as described above, and updates the threshold arrangement asymptotic value stored in the RAM. Then, the threshold decreases from 0.5 to 0.45, so the possibility of exceeding the threshold is high, but if the operation not exceeding the threshold is continued, the correction coefficient is 1.1, and the corrected travel distance is more than the actual travel distance Is larger. Further, assuming that each asymptotic value is set as shown in FIG. 30 (b), the normal correction coefficient is 1.8 at the maximum and 0.2 at the minimum.

  The input interface displayed to the driver is an input screen for specifying relative levels of multiple levels as shown in FIG. 30 (c), so internal data shown in FIGS. 30 (a) and 30 (b) Even if the specific values of (the threshold value and the asymptotic value) are changed, the input screen seen by the driver does not have to be changed. Therefore, since the user interface does not change, the operability can be maintained good. Then, the driver only has to specify the levels in a plurality of stages from "severe (hard)" to "loose (easy)", and can intuitively specify the setting conditions. Also, under the current setting conditions, if the conditions are not often satisfied, the setting conditions are relaxed by one or more steps, and conversely, if the setting conditions are always satisfied, the setting conditions are tightened by one or more steps Can be adjusted to increase the amount of change, making it easy to set appropriate conditions.

  Thus, since the threshold can be set individually, the driver sets the threshold in such a combination that high scores (high normal correction factor) can be obtained while driving in which acceleration in any direction does not exceed the threshold. it can.

  For example, depending on the user's driving habit, the characteristics of the vehicle, the condition of the road on which the vehicle is traveling, the installation position of the machine equipped with this system, etc. , May not be. Therefore, by setting the setting conditions individually, it is possible to increase the normal correction coefficient while satisfying the setting conditions of all the sets for the four detection targets. As a habit of driving, in the case of a driver who does not change speed very much but makes a sudden lane change, he is sensitive (e.g. 5 or 6) to rapid acceleration or rapid deceleration, and insensitive to left and right sudden steering ( For example, set 1).

  In addition, for example, in the case of a manual car, the characteristic of the vehicle tends to be a sudden start, so detection of rapid acceleration is made insensitive and others are made standard or sensitive. Further, more specifically, if the installation position of the acceleration sensor 22 in the vehicle is at the center in the width direction of the vehicle than the installation position of the radar detector 1, the sensitivities of the left and right quick steering wheels are the same. If it is shifted to either of the two, the lateral force of the acceleration sensor differs between right turn and left turn, so it is preferable to make one of the sensitivities more sensitive and the other less sensitive.

(Modification to restore the correction coefficient: especially using the distance constant d)
In the embodiment described above, the distance constant d is set to 10 when the engine is on. However, even if the engine is turned off, if the traveling distance L is stored, since L is a predetermined large value after the engine is turned on, it is not necessary to cope with it.

  In addition, although it is a fixed value when acceleration exceeds a threshold and L is reset to 0, in the embodiment described above, one fixed value (for example, 100) is used, but the number of times acceleration exceeds the threshold is It is better to increase the distance constant d as it increases. For example, d after exceeding the first threshold value is set to 100, 500 for the second time, 1000 for the third time, 5000 for the fourth time, and 10000 for the fifth time and thereafter. By changing d, a violation is repeatedly made, and in the case of a malicious case, a period (here, a traveling distance) required to return to the normal correction coefficient also takes a long time. In this case, as the number of times the acceleration exceeds the threshold increases, the travel distance required to return to the normal correction coefficient becomes longer, and the correction coefficient becomes lower over a longer time, and the correction total travel distance increases (increases The change amount of) becomes worse. Therefore, the driver can expect to drive with caution so as not to exceed the acceleration once the driver drives the vehicle once the acceleration exceeds the threshold.

  This means that when the acceleration exceeds a threshold value, for example, the character who is also a passenger has a feeling that he / she feels bad, feels uncomfortable and feels poor. Then, when the state is repeatedly performed, the user's mentality when the character is given personality and emotion is also deteriorated, and it takes a long time to recover the mood. The increase of d also shows the change of the mentality of the character.

  In the embodiment and the modification described above, the travel distance required to return to the normal correction coefficient is determined by d, and the correction coefficient is gradually increased according to a predetermined function until the travel distance is reached. I made it. The present invention is not limited to this, and steps may be made to step up and be discretely increased, and a predetermined period (for example, traveling a certain distance traveled) may be a low correction coefficient with a reduced correction period. The normal correction coefficient may be returned immediately after the lapse. The fixed traveling distance may be fixed or may be increased as the number of times the acceleration exceeds the threshold increases as in the present modification.

(Modified example 1 of adjustment of correction coefficient: Adjustment 1 associated with overspeeding)
In the above-described embodiment, the acceleration is used as information associated with the traveling of the vehicle to be subjected to the negative assessment to reduce the correction coefficient, but in the present embodiment, the vehicle speed is also added to one of the conditions. Specifically, when traveling at a point where the speed limit is set while the vehicle speed is in excess of the speed limit, it is a violation of the speed limit of the traffic rules, so a negative assessment will be made to reduce the correction factor. Do. In this case, it is common to slightly exceed the speed limit, and it is rather dangerous to run at the speed limit against the flow of surrounding vehicles. So, in this modification, not a speed limit itself but a speed higher than the speed limit by a set speed is set as a first reference speed as a determination reference of whether the speed is over or not. In other words, if the current vehicle speed exceeds the first reference speed, the correction factor decreases to make a negative assessment, and even if the speed limit is exceeded, if the first reference speed is below the negative assessment Not performed. The set speed may be set to, for example, 20 km / h. For example, overspeeds of several kilometers per hour are likely to occur as a result of going downhill or the speed of the surrounding vehicles becoming higher overall. Then, when the surrounding vehicles are traveling at the speed limit or higher overall, if only the host vehicle is traveling in compliance with the speed limit, a dangerous state will be caused. Therefore, by setting such that the control of the negative assessment to the correction coefficient does not occur even if the speed is slightly exceeded, it is possible to drive along the flow of the surrounding vehicle. On the other hand, speeds exceeding 20 km / h are less likely to cause such a situation, and the degree of danger increases. This becomes a criterion that the degree of danger also increases because the number of violation points at the time of a traffic violation will also be 2 points if the speed exceeds 20 km / h. Therefore, we made a negative assessment at a set speed of 20 km / h.

In addition, in the control for reducing the correction coefficient based on acceleration, when the threshold value is exceeded, the correction coefficient is uniformly dropped to a predetermined value (for example, 0) regardless of the value of the correction coefficient at that time or the extent to which the threshold value is exceeded. However, the adjustment control associated with the speed over in this modification changes the effect of reducing the correction factor according to the magnitude of the over speed. It is said that overspeeding is more dangerous as the overspeed from the speed limit is greater, even if the speed overrun is the same. Therefore, the larger the degree of violation (overspeed), the lower the effect of the decrease in the correction coefficient, that is, the lower the rate of increase in the corrected total travel distance associated with actual driving. Specifically, the control unit 18 acquires the current position information of the vehicle stored in the RAM, acquires the speed limit set at the current position from the map information stored in the database 19, and the first standard Find the speed (speed limit + set speed). Further, the control unit 18 acquires the vehicle speed from the OBD information recorded in the RAM, and determines whether the vehicle speed exceeds the first reference speed. When the first reference speed is exceeded, the control unit 18 calculates the correction coefficient based on the following equation (1).


Correction coefficient = − (M ^ 2 * L) / (ML + d) (1)
M = (k-(m / 1000)) * v ^ 2

Here, m is the normal correction coefficient (the value at which the asymptotic line converges)
L is the distance traveled since acceleration exceeds the threshold (actual distance traveled) Units are meters d is the distance constant
(When the engine is on: 10
After reaction by acceleration sensor: Fixed value greater than 10 eg 100)
k is the velocity coefficient (eg 0.0025)
v is over speed (vehicle speed-first reference speed)

On the other hand, when the vehicle speed does not exceed the first reference speed or when the information on the speed limit is not registered, the control unit 18 obtains a correction coefficient based on the following equation (2). The calculation of the correction coefficient is the same as that of the basic embodiment described above.
Correction coefficient = (m ^ 2 * L) / (mL + d) (2)

  For example, when traveling at 81 km / h at a point where the speed limit is set to 60 km / h, the correction coefficient is determined using the above equation (1) since the first reference speed is exceeded. Further, in this case, since the overspeed v is 1 km / h, the value of M is “k− (m / 1000)”. When traveling at the same point at 85 km / h, the overspeed v is 5 km / h, so the value of M is “(k− (m / 1000)) * 25”. If L is sufficiently large, the correction coefficient obtained by equation (1) is approximately equal to the value of M. Therefore, the larger the overspeed v, the larger the absolute value of the correction coefficient. If the value of L is not sufficiently large, as in the above-described embodiment, the tendency is that the absolute value of M increases as the overspeed v increases, although the absolute value is smaller than M, as in the above-described embodiment.

  Since the correction coefficient takes a negative value, if the vehicle travels beyond the first reference speed, the corrected total traveling distance decreases as the vehicle travels. Then, since the correction coefficient is determined in consideration of the overspeed v, the degree of decrease of the corrected total traveling distance when traveling over the same distance is larger when the overspeed v is 5 km / h than 1 km / h. Since the value of M increases exponentially with the magnitude of the overspeed, the greater the overspeed, the greater the penalty.

  On the other hand, for example, when the vehicle speed is 70 km / h, the vehicle speed is equal to or less than the first reference speed, and the control unit 18 obtains the correction coefficient based on the above equation (2). Since the correction coefficient takes a positive value, the corrected total travel distance accompanying the traveling of the speed always increases. Therefore, the driver tries to drive at a speed lower than the first reference speed so as not to make the correction coefficient negative.

  Moreover, in said modification, 20 km / h was shown as an example of setting speed. The set speed may be a fixed value or may be switched according to another condition. Another condition is, for example, the speed limit of a freeway. Since the speed limit is 80 km / h or 100 km / h for a normal expressway, the first reference speed in such a case is 100 km / h or 120 km / h. On the other hand, for expressways with a speed limit of less than 80 km / h, the set speed is increased (for example, 30 km / h or 40 km / h). Further, instead of adding the set speed to the speed limit, the first reference speed may be faster than the speed obtained by adding the set speed to the speed limit regardless of the speed limit. This high speed is, for example, 100 km / h.

  For example, there is one in which the speed limit is set to 60 km, which is slower than the speed limit of a general expressway, such as the Metropolitan Expressway. On expressways with low speed limits, surrounding vehicles may travel at speeds similar to or near the speed limit of general expressways (for example, 90 to 100 km / h). In such a case, it is important to observe the traffic rules, but if only the host vehicle is traveling at the speed limit of 60 km, the speed difference with other vehicles is 30 to 40 km per hour, which is dangerous. Therefore, safe driving can be promoted by preventing the occurrence of a negative assessment based on an overspeed even when traveling according to the surroundings.

(Modification 2 of adjustment of correction coefficient: adjustment with violation of suspension)
In this modification, the amount of change, that is, the correction coefficient is reduced under certain conditions when a traffic violation occurs. The target traffic violation was a suspension violation. When a temporary stop violation is made, the control unit 18 subtracts a predetermined value from the current correction coefficient to obtain a correction coefficient. Since the predetermined value is subtracted, the obtained correction coefficient may be negative. Furthermore, when the suspension violation was made multiple times at the same point, the predetermined value to be subtracted was increased. Repeating the same type multiple times in the same place is not as alert and may be worse off than the first time, so if you repeat multiple times, you greatly reduce the correction factor and make it a smaller value The increase in the corrected total travel distance with the increase in distance was made worse. In this way, the user can expect to drive in an effort not to violate traffic.

  Furthermore, in the case of the first suspension violation, a delay was given without subtracting the correction factor of the warning. As a result, since the correction factor does not decrease in the first violation, the driver's motivation can not be lowered, and it can be warned that the second violation will not occur, and as a result, safe driving can be promoted. In addition, as a warning in the case of the first violation, for example, immediately after making a suspension violation, it would not be possible to output voice information such as "You would not stop now, stop now" or paused When going to a place after that, it is good to output a warning by voice information such as "I would not have stopped last time, please stop this time, for example" from the speaker 16 before that. It is good to change the warning message by the voice to be output according to the closeness.

  In this way, it is not the case that the correction factor is lowered immediately after the first violation, but it is warned that the correction factor will decrease if the same kind of violation is made as a warning, and the correction will be made the same kind of violation next time It is good to lower the coefficient. Instead of suddenly lowering the correction coefficient, warning can urge the user not to violate. If the same violation is made in spite of the warning, the advice from the character is ignored, and control is performed to lower the correction coefficient.

  Specifically, the control unit 18 acquires current position information from vehicle position coordinates stored in the RAM, accesses map information stored in the database 19 based on the acquired position information, and temporarily stops around the vehicle. Identify the location of In addition, the control unit 18 acquires the vehicle speed included in the OBD information stored in the RAM, and determines whether the vehicle has been temporarily stopped at the temporary stop location. Since the periodic processing is performed every one second, it is determined whether the vehicle speed is 0 continues for a plurality of cycles or not.

  If not suspended, the control unit 18 searches for the violation status stored in the EEPROM and determines whether there is a suspension violation for the same place, and if not, the first time at the same place And the position information of the place where the suspension was not stopped and the number of violations (1) are stored. Also, if there is a record of a suspension violation at the same place, the number of violations associated with it is read and incremented by one, and the information on the number of violations in the EEPROM is updated to a new number.

Then, the control unit 18 obtains the acquired number of violations (in the case of the first case, 1. If there is a violation history in the past, the number of violations read from the EEPROM is incremented by 1), and the correction coefficient is calculated based on the following equation. Ask.

Correction coefficient = (m ^ 2 * L) / (mL + d)-s | 1-(t ^ 2 / τ ^ 2) |

Here, m is the normal correction coefficient (the value at which the asymptotic line converges)
L is the distance traveled since acceleration exceeds the threshold (actual distance traveled) Units are meters d is the distance constant
(When the engine is on: 10
After reaction by acceleration sensor: Fixed value greater than 10 eg 100)

s is the suspension deduction coefficient Number of violations at the same place 1 time 0:
Second offense at the same place: 0.5
Number of violations at same place: 1
4 or more violations at the same place: 2
τ is a mood recovery time constant 600 (10 minutes complete recovery)
t is the elapsed time from the suspension violation (seconds)

  In the above equation, the first term is the control of the correction coefficient based on the same acceleration as that of the embodiment, and the second term is the point deduction control due to the suspension violation. In the case of the first violation, since the suspension deduction coefficient s is 0, deduction is not made. Since t is 0 at the time of the suspension violation, the suspension deduction coefficient s is subtracted from the current correction coefficient. Since the temporary stop point deduction coefficient s becomes larger as the number of times increases, the correction coefficient is also greatly reduced and becomes a smaller value. For example, even if the normal correction coefficient is 1 or 1.2 or the like, since the temporary stop deduction coefficient s is 2 after the fourth number of violations in the same place, the correction coefficient becomes negative at a stretch. In addition, even if the number of violations at the same place is the third one, when the correction coefficient at the normal time is set to a lower value such as 0.8, the correction coefficient has a negative value. Furthermore, even if it is the second time etc., if the temporary stop violation is made in the section where the correction coefficient is reduced by the control based on the acceleration according to the first term, the value of the correction coefficient becomes negative.

  This negative section has a very large penalty that the corrected total travel distance decreases as the travel distance increases. Therefore, the driver should keep in mind that the vehicle is temporarily stopped at the place of the temporary stop, resulting in safe driving.

  In addition, the period which the deduction by a temporary stop violation is affecting is prescribed | regulated by elapsed time (tau). As can be seen from the second term, in this modification, it is fixed at 600 seconds = 10 minutes at which t = τ, but τ may also be changed depending on the number of violations. For example, the second recovery may take 10 minutes, the third may take 30 minutes, and the fourth may take 60 minutes.

(Modification example 3 of adjustment of correction coefficient: adjustment with speed excess 2)
In the first modification, the correction coefficient takes a negative value when the first reference speed is exceeded. Therefore, when traveling at a speed equal to or less than the first reference speed, if the correction coefficient is a positive value and exceeds the first reference speed even by 1 km / h, the correction coefficient drops to a negative value at a stretch. On the other hand, in the third modification, although control is performed to reduce the correction coefficient when the first reference speed is exceeded, a positive value is set. As control to reduce this correction coefficient within the positive range, for example, L in the equation (Equation (2) in deformability 1) for obtaining the correction coefficient in the embodiment described above is appropriately set according to the overspeed v Set to In this way, when the acceleration exceeds the threshold value, the correction coefficient is once reset to 0, but in the case of deduction due to overspeed, the value is restarted from the value of the correction coefficient corresponding to L according to overspeed v. It will increase. Further, as in the case of the point deduction due to the temporary stop in the second modification, a deduction point due to overspeed may be separately provided.

  Furthermore, a second reference speed exceeding the first reference speed is set, and when the second reference speed is exceeded, the correction coefficient corresponding to the excess speed when the first reference speed is exceeded is lowered. You should lower it too much. In this case, the second reference speed may be, for example, a speed (one exceeding 30 km per hour) at which a one-shot stoppage is required. An overspeed condition that results in a single-stop operation can be said to be a very dangerous driving condition leading to a major accident. In such an operating state, the correction factor may be greatly reduced, that is, a very small value (for example, a negative value). By setting it like this, on the contrary, the driver will drive with caution so as not to cause such a situation, and as a result, there will be no excessive speed exceeding the above-mentioned set speed. Can be

(Modified example with control function to deteriorate relationship (closeness))
Although the embodiment and each modification described above influence the increase in closeness that indicates the relationship finally by controlling the value of the correction coefficient, this modification degrades the relationship. As a function to perform control, it has a control function that greatly reduces / deducts the corrected total travel distance, which is directly linked to the determination of closeness. If this worse control is performed when the set demerit point condition is satisfied, the relationship stored up to now collapses at a stretch, and the user makes an effort to avoid such a situation. Can be expected.

  The degree of the penalty may be very large compared to the control of the correction factor based on the speed exceeding etc. exceeding the first reference speed, and this demerit condition is made more serious. In the case of overspeeding, for example, it is preferable to exceed the third reference speed which is higher than the first reference speed. The third reference speed may be, for example, 30 km / h more than the speed limit at which a one-shot operation is suspended. An overspeed condition that results in a single-stop operation can be said to be a very dangerous driving condition leading to a major accident. In such a driving state, assuming that the character also has a personality as compared with the case of slight overspeed, it can be predicted that the intimacy and reliability with respect to the driver user are also reduced. Therefore, the corrected total travel distance is greatly reduced. The distance to be lowered is set to an excessive amount of, for example, 1000 km units. Conversely, the user operates with caution so as not to cause such a situation, and as a result, an excessive speed exceeding the above set speed is caused. Safe driving can be promoted without any problems. In addition, as an example (more than 30 km / h) of the third reference speed, the same reference speed as the second reference speed shown in the third modification described above is shown, but the specific speed may be the same or different good. Set appropriately according to the purpose.

  Furthermore, N or more (for example, three times in a row) violations are made as a deduction condition that greatly reduces the corrected total travel distance. For example, in the case of a violation such as overspeed, it is difficult to quickly return to below the speed limit even if you notice overspeed, and it is dangerous to suddenly reduce the speed to get under the speed limit. is there. On the other hand, if overspeed is continuously continued for a fixed period, it can be estimated that there is no intention to decelerate and keep the speed limit, and it is dangerous operation.

  At this time, a warning or the like is given by voice etc. until [N-1] times. As a warning, for example, if the same type of violation is subsequently made, it is predicted that the reliability will be lowered, and if the same type of violation continues, the corrected total traveling distance due to the closeness is greatly reduced. It is possible to prompt the user to reduce the speed by warning rather than suddenly. If the same violation is made in spite of the warning, the advice from the character is ignored, and control is performed to lower the corrected total travel distance.

  Specifically, the control unit 18 periodically acquires (for example, one second) the vehicle speed included in the OBD information of the RAM, and determines whether the vehicle speed exceeds the third reference speed. If it is lower than the third reference speed, the current determination ends. If the third reference speed is exceeded, the controller 18 issues a first warning. After that, it is judged regularly whether the third reference speed is exceeded. If, during continuous monitoring, the vehicle speed falls below the third reference speed even once, it is assumed that the current series of overspeed conditions has been resolved. If the vehicle speed exceeds the third reference speed thereafter, the first warning is issued again. In addition, when the state in which the third reference speed is exceeded continues for a predetermined time (for example, 3 minutes), the control unit 18 performs a second warning. After that, the control unit 18 continuously and periodically acquires the vehicle speed and compares it with the third reference speed. Then, it is assumed that the current series of excessive speed conditions is eliminated when the vehicle speed becomes lower than the third reference speed even once. Therefore, when the vehicle speed exceeds the third reference speed thereafter, the control unit 18 issues a first warning again. On the other hand, if the state exceeding the third reference speed continues for a predetermined time (for example, 3 minutes) after the second warning, the control unit 18 subtracts the correction total traveling distance by a predetermined distance (for example, 1000 km). When traveling continuously at a speed exceeding the third reference speed for six minutes, there is no intention to keep up with the speed limit and the intimacy of the character is greatly reduced because the character's request is not heard.

  In addition, when traveling at a speed exceeding the third reference speed for six minutes, it is preferable to obtain an output of character information (that does not display the character) that makes the character not angry. In this case, in addition to the driver's subtraction of the corrected total travel distance and a decrease in the intimacy, the character information is not output as if the character left home, so the driver can not see the character and becomes sad. Therefore, the driver should keep in mind driving that does not satisfy the set conditions, so if the driving set as shown in this modification is undesirable driving such as very dangerous driving, the driver is appropriate. It is good because you will be driving.

(Modified example provided with character information (night drive mode) output stochastically)
Although the embodiment has also been described, the character information extracts the corresponding character information from the internal data shown in FIGS. 20 to 24 based on the OBD information, the position information, the map information, etc. acquired by the control unit 18 and outputs Do. In this modification, the character information is provided with stochastic output, and the relationship affects this probability. In this way, the probability of the predetermined character information being output is influenced by the relationship, and the game is more interesting.

  Character information that appears due to this probability is a night drive mode that is output in the night time zone. That is, as described in the embodiment, “(3) sleeping word during bedtime” (FIG. 24) outputs character information that says sleeping word in a cycle of 5 minutes in 10 minutes to 30 minutes in the night time zone . That is, since the character is also a living thing and sleeps in the night time zone, even if there are surrounding target objects, it does not notify of the presence of the target object as in the daytime time zone. In other words, the output content of the character information differs depending on the time zone, the daytime zone is the normal operation time zone where the character wakes up and performs various notifications, and the nighttime zone is sleeping and the main activity is There is a non-normal (standby) operating time zone.

  Then, for example, when the driver travels mainly in the night time zone, since character information indicating a sleeping state is output like a sleeping word, it lacks interest. In such a case, the operation time zone may be set to be reversed between day and night, but it is not preferable to go to bed at night by going to work at night because the character of the character is lacking. Therefore, in this modification, the drive mode is a function that performs normal operations such as output of character information in the daytime zone based on the relationship (closeness) even if the character wakes up with probability and is in the nighttime zone as a drive mode Equipped with This makes the game more interesting since it works several times once at night. Moreover, since the sleeping character wakes up for himself and notifies the presence of the target object and performs normal operations during the daytime, it is good to be thrilled.

  And game nature increases more by associating the operation probability with the relation (closeness). In particular, it is preferable for the user to keep in mind that the relationship is better if the relationship is improved and the probability of operation is increased.

  Specifically, when the display unit 5 is touched twice in the night time zone, the control unit 18 determines whether to perform the daytime operation with a predetermined probability. The second touch represents a state of tapping "Tsuntsun" or "Tontonn" to wake up the sleeping person. The probability of whether or not this night drive mode is activated is increased according to the height of the relationship / closeness. In the embodiment described above, the familiarity is divided into four stages from 0 to 3, so for example, when the familiarity is 0, the probability is 1/4 and when the familiarity is 1, the probability is 1/2, When the closeness is 2, the probability may be 3/4, and when the closeness is 3, the probability may be 1/1 (100%).

Also, instead of the rough division like this four steps, it may be divided more finely. For example, the level of intimacy for night drive mode Level = corrected total travel distance / 10000
And (in 10km every level increases one),
Level * 0.25 [%]
In the probability of the character, the drive mode is activated in response to the invitation and outputs various character information. In this way, when the distance exceeds 4000 km, the probability exceeds 100%, so that it always starts.

  In addition, it is preferable that the character operating in the night drive mode wear a dressed up night drive wear.

(Modification 4 of adjustment of correction coefficient: Adjustment according to eco-driving situation)
In this modification, the eco-driving situation is used as information when adjusting the correction coefficient. The eco-driving is determined based on, for example, fuel consumption. Then, when it is determined that the eco-driving is performed, the control unit 18 performs a positive assessment and increases the correction coefficient by a predetermined value.

  The OBD information includes the present fuel consumption, which is the average fuel consumption from the engine ON, the instantaneous fuel consumption (every 200 ms), and the lifetime fuel consumption, which is the average fuel consumption including the fuel consumption in the past. Since the information related to the fuel efficiency is stored in the OBD information of the RAM, the control unit 18 reads and compares the instantaneous fuel efficiency stored in the RAM and the current fuel efficiency, and the instantaneous fuel efficiency is larger (fuel efficiency is better) In the case where eco-driving is performed, a predetermined increase value (for example, 0.5) is added to the correction coefficient. Then, for example, when the normal time correction coefficient is 2, the correction coefficient is increased to 2.5 while the eco-driving is being performed.

  This time, since the fuel efficiency is an average of the instantaneous fuel consumption history from the engine ON, when the instantaneous fuel efficiency increases, then it is reflected in the fuel efficiency this time, and when the instantaneous fuel efficiency decreases, then it is reflected in the fuel efficiency this time Being lowered. Therefore, the instantaneous fuel consumption can not continue the state of the eco state higher than the fuel consumption this time, and the instantaneous fuel consumption alternately exceeds or falls below the fuel consumption this time. Only positive assessment was adopted because both conditions occur.

  In particular, during a period in which a foot brake or an engine brake is used without stepping on the access pedal, such as at the time of stopping, the instantaneous fuel consumption may be high, so that such a condition may be generated. Then, evaluation of the current driving (whether or not eco-friendly) can be promptly performed.

  The driver positively drives eco-driving in an attempt to obtain a positive assessment. Eco-driving is preferable because it consumes less fuel, is economical, is also environmentally friendly, and has a low speed fluctuation, resulting in a comfortable ride.

(Modification on output of character information)
In this modification, the control unit has a function of preventing the output of the character information until the return condition is satisfied, when the set condition (home leaving condition) is satisfied. The conditions for leaving home include, for example, violent driving and not listening to what the character says. Rough driving may be, for example, when driving is performed above a predetermined speed (for example, a third reference speed), or when acceleration exceeds a threshold value a plurality of times over a predetermined period. If the character does not know what to say, there is a case where, despite the warning, the driving is continued without following the warning.

  The return condition may be, for example, a fixed condition such as elapse of a predetermined time or traveling of a predetermined traveling distance, or provision of a predetermined item to be described later. The predetermined time may be, for example, the operating time of the present system or the elapsed time in the real world. When the character information is not output, the user can not meet the character and becomes sad. Then, since the user tries to drive the vehicle so as not to satisfy the set condition, if the set condition is an undesirable operation such as a very dangerous drive, the user will perform the appropriate drive. good. Also, even if character information is not output once, for example, character information is output again if the fixed condition is cleared, but if it does not wait for the fixed condition to be cleared, for example, provision of an item etc. By incorporating a mechanism in which character information is output under a special return condition, the user performs an action for acquiring an item, and the game is enhanced. For example, the item is obtained by actually moving to a predetermined place, or accessing a predetermined server / site and obtaining for free or for free.

(Modified example with item get function)
The installation point of the item which affects the state of the character is set on the map, and when the vehicle goes to the location of the installation point, the item is obtained with a certain probability. The installation point may be, for example, SA or PA on a highway, view point parking which is a parking lot in a good scenic spot, a station on a general roadway, or a highway oasis. In this case, stopping at the parking lot at the installation point may be a condition for getting the item.

All of them have a parking facility, so they may stop for a break in the middle of driving, which is preferable because the driver can be given a rest by using these parking facilities. The requirement for stopping at the parking lot is to exclude passing of a simple SA or the like.

  Items you get can be saved and used to affect the character's state. The state of the character affects the output of character information, which may increase the game nature.

  Items are, for example, items for improving the relationship (closeness) (such as adding a predetermined distance to the corrected total travel distance stored in the RAM), an item in which the correction coefficient does not decrease for a fixed period, There are an item in which the correction coefficient returns to the normal correction coefficient, an item in which the character disappears from the screen (returns to the screen), and an item in which the probability that the night mode is activated is increased.

  For example, as an item in which the correction coefficient does not decrease, there is, for example, a drunken drink. When the drunken drink is taken, the acceleration sensor does not respond over a certain period (time, traveling distance, etc.), that is, control is performed so that the correction coefficient does not decrease even if the acceleration may exceed a threshold. That is, the control unit 18 adds without resetting L even if the acceleration exceeds the threshold. As a result, for example, a curve continues on a mountain road, and even when acceleration in the left-right direction tends to exceed the threshold, driving can be performed without concern for the acceleration. Since it is good to drink this drunk stop drink in front of a mountain road, it is good to install it, for example, at the footway station.

  The item which comes back from the state where the character disappears from the screen (appears on the screen) is, for example, a present item. That is, the character does not appear when the condition for leaving the house, for example, continuously exceeds the third reference speed three times. In such a case, if a predetermined return condition is satisfied, for example, 24 hours have passed, the character appears on the display unit again, but giving a present item causes the character's mood to return immediately to appear on the display unit and return.

  In order to obtain this character, the control unit 18 first reads out the vehicle position coordinates stored in the RAM to recognize the current position, and determines from the map information stored in the database 19 whether or not there is an item installation location around it. . Then, if there is an installation place, it is determined based on the set probability whether or not an item set in the installation place can be provided. Then, when an item can be provided, the control unit 18 utters an item get flag phrase and guides it there. Such guidance is, for example, information for specifying a place where an item is set (information on position or notification of equipment name (○ service area)), voice only, character display In some cases, the predetermined animation or the icon of the corresponding equipment displayed on the display unit may be highlighted.

  The condition for the item to be available is, in addition to the fact that the available condition is selected according to the above probability, the correction coefficient needs to be a certain threshold or more (safe operation state). Furthermore, since the SA / PA and the like are arranged on the expressway, if the current traveling position of the vehicle does not identify the expressway, the item get phrase is not uttered even if it is near.

  When the driver knows that a predetermined item is present around by the item get flag phrase or the like, the driver determines whether the item is a necessary item or not and moves to the target object if necessary. An item can be obtained by stopping at the target object (parking lot). The acquired item may be stored, for example, in the RAM or in the EEPROM. In addition, since the road station is on a general road, it can be stopped relatively easily several times. Therefore, the same item item get is limited to one per day.

(Other modifications)
The reduction range of the change amount when the setting condition is not satisfied may be constant regardless of whether the setting condition is severe or not, and the reduction range may be different according to the degree of difficulty of the setting condition. In the embodiment and the modification described above, the change due to the closeness is only character voice, but the character image may be changed. Although the vehicle speed is acquired using the vehicle speed information included in the OBD information, the present invention is not limited to this, and the speed may be calculated based on, for example, the history of position information. Further, it is preferable that the number and frequency of the character outputting voice and chatter increase as the degree of familiarity increases. Further, the control for improving the closeness may be performed based on the traveling speed, or based on the power on time or the like.

  In the above embodiment and modification, the radar detector of the type fixedly installed by attaching using the bracket 3 at a predetermined position in a dashboard or other vehicle as an application device of the system of the present invention has been described as an example However, it can be applied to a mirror type radar detector attached to a rearview mirror. Furthermore, the present invention is not limited to the radar detector, and can be implemented as a function of various on-vehicle electronic devices. For example, it may be incorporated as a function of a navigation device or the like.

  In the embodiment and the modification described above, the apparatus includes the database 19 storing various information in the apparatus, and the control unit 18 accesses the database 19 to read necessary information and performs various processes. There is no limitation to this. That is, part or all of the information registered in the database 19 is registered in the server. The radar detector and other electronic devices / devices may have a function of communicating with such a server, and the control unit 18 may appropriately access the server, acquire necessary information, and execute processing. A part or all of the control unit may be mounted on such a server, a part of the processing may be executed on the server side, and the result may be acquired on the on-vehicle device side, and a predetermined display may be performed. Furthermore, the display device may use another in-vehicle device or a device mounted on a vehicle.

  Although the embodiment incorporates a GPS receiver for detecting current position information, the present invention does not require a configuration including a GPS receiver, and acquires current position information from a vehicle or another vehicle-mounted device, and acquires the acquired information Based on the above, it may be judged whether or not there is an approaching relationship with the alarm target.
