Description

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

  For example, Patent Literature 1 discloses a system that changes character information such as the facial expression and gesture of a character displayed on a display screen in accordance with the situation of the vehicle. The invention disclosed in Patent Document 1 expresses a virtual emotion based on a facial expression of a character, assuming that the vehicle has a personality. For example, if the driver is driving violently, and the vehicle has emotions, the vehicle will feel uncomfortable, so the virtual emotions of the car might be angry or sad Output. On the other hand, if the driver is driving gently and gently, the virtual feeling of the vehicle is considered to be comfortable, so an expression that makes the character happy or cheerful is output.

  The above system encourages the driver to drive safely by making use of emotions that the driver does not make 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 feel strongly that he / she does not make the character uncomfortable or desires to be pleased. Therefore, it is necessary for the driver to strongly empathize with the character. However, in the system disclosed in Patent Document 1, for example, when the driver's driving is violent or polite, the character's facial expression is the driving state. It is determined uniformly according to. Since the facial expression and gesture of the character displayed on the display screen are monotonous and poorly changed in this way, the driver is easily bored with communication with the character. Therefore, the state in which the driver is strongly empathized with the character does not continue, and the driver may eventually feel nothing even when the facial expression or gesture of the character changes. As a result, the above-described system has a problem that safe driving cannot be promoted.

  Further, apart from whether or not emotions are transferred, for example, if the output of character information is rich in change, the game performance becomes high. Then, in order to clear the game, the driver tries to drive and run in a desired state. However, as described above, the system disclosed in Patent Document 1 has a problem that the game performance is low because the change of the character is poor.

  An object of the present invention is to provide a system and a program that can continuously encourage a driver to drive safely by maintaining a strong emotional transfer of the driver to a 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 in accordance with the relationship, and has a function of improving the relationship and driving of the vehicle A function for controlling the amount of change when the relationship is favorably changed based on the information on the relationship.

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

  This system outputs character information according to the relationship with the user. The relationship is the degree of association, relationship, etc. between the user and the character, and may be taken as, for example, familiarity, reliability, etc. Good relationship means that the relationship between the user and the character is good, and it may be considered that the relationship is high or strong. By outputting the character information corresponding to the relationship with the character, the user can easily transfer emotions to the character, and the user can feel as if the character is a real target.

  The character information is, for example, a kind of reward that is more enjoyable for the user because it flies to variations as the relationship is better, and the user has a better relationship. The operation to become. Therefore, for example, if the mechanism is such that the relationship becomes better as the vehicle is driven safely, the user can maintain the relationship with the character in a good condition and the degree of goodness can be further increased. , You will actively try to drive safely.

  Since the character information is in accordance with the relationship, the output information varies depending on the degree and degree of goodness. Different output modes, for example, although the output means and medium, such as the fact that it was initially only an image with audio, are different, the initial still image was displayed as an animation, or even the same still image has a different costume Or the content of the output is different by the same output means / medium.

  The function of improving the relationship is, for example, that the relationship is good based on the acquired predetermined information, that is, the degree of goodness is high and strong. In general, the longer you are together, the better the relationship. Therefore, the predetermined information is information relating to the travel of the vehicle such as a travel distance, for example, and it may be controlled so that the relationship becomes better as the travel distance becomes longer. The longer the distance traveled, the longer the period of being with the user, and the better the relationship because the long distance was driven together. In view of the fact that the relationship becomes better as they stay together longer, for example, the operation time may be used. The operation time is also particularly good when the engine is operating, for example, from when the ignition is turned on to when it is turned off as vehicle information. In this way, the operation time is such that the user and the character are on the vehicle together. It can be taken as boarding time. As described above, the function for improving the relationship is preferably controlled so that the relationship becomes better as the time spent together becomes longer. The function for improving the relationship may perform control for improving the relationship based on information other than the exemplified travel distance and operation time.

  As information for performing control for improving the relationship, the travel distance is preferable when the travel distance is compared with the operation time. For example, if the vehicle is parked and stopped with the engine running, the travel distance is 0, and if the vehicle travels for the same time as the parked time, the travel distance increases. If the control that makes the relationship good based on the movement time is performed, the relationship becomes good to the same extent, but if the character is given personality, ride on the parked vehicle together It is better to be based on the distance traveled because the character is more happy than the character actually travels. Furthermore, when the vehicle is parked or stopped, a driver who is a user may be sleeping with the engine running. Then, the character is alone and it is difficult to say that the sensitivity with the user is improved. On the other hand, when the vehicle is running, it is guaranteed that the driver who is the user is awake and is with the character. Even in view of this point, it is preferable to use the travel distance. Further, when traveling in the city area and in the suburbs for the same time, the travel distance becomes longer when traveling in the suburbs where there is less signal waiting and the speed is faster. Furthermore, if the expressway is used, the travel distance becomes longer. When traveling in urban areas, there is a high possibility of traveling for regular activities such as commuting and shopping, and when using the suburbs and highways, there is a high possibility of traveling for fun events such as travel. I can say that. Therefore, it is preferable to use the travel distance so that such a difference causes a difference in control for improving the relationship. Furthermore, when it is assumed that the operating time is, for example, when this system is mounted on a portable device and the vehicle can be removed and carried, the power is supplied from a commercial power supply, etc., not from the vehicle battery, The system can be operated with the power turned on regardless of running. Then, even if the user is away from the portable device with the power turned on as described above, the control is performed so that the operation time is added and improved, which is not preferable. Therefore, it can be said that it is fair and preferable to perform control for improving the relationship based on the travel distance.

  Since it has a function of controlling the amount of change when the relationship is changed favorably based on information related to vehicle travel, for example, the function for improving the relationship is an opportunity to perform good control acquired. Even if the predetermined information is the same, if the amount of change based on the predetermined information is different, the degree and degree of goodness of the relationship are different. Therefore, even if the input information (predetermined information obtained above) is the same, the output results may be different, so that the system is interesting and rich in game characteristics. Furthermore, since the control of the change amount is performed based on information related to the traveling of the vehicle, the change amount becomes larger or smaller depending on the actual driving of the driver. Therefore, the greater the amount of change, the more efficiently the relationship becomes better. Therefore, when the driver who is the user tries to increase the relationship, he / she tries to drive the vehicle so that the amount of change becomes large.

  The amount of change is controlled, for example, by adding a predetermined parameter to the input information (the acquired predetermined information) that makes the relationship favorable. In addition, for example, a parameter (coefficient) is multiplied, or a parameter (predetermined value) is added / subtracted every time a certain amount of input information is reached. Further, the change amount may be changed according to a predetermined function, or the change amount may be changed according to a predetermined rule.

  (2) The character information may be a reward that the user is more pleased with the better the relationship. In this case, as described in (1), the user is strongly motivated to perform an operation / driving so as to maintain a good relationship so as to receive a reward or to improve the relationship. Become.

  (3) It is good to provide the alerting | reporting means which alert | reports the information regarding the said said variation | change_quantity in the function which controls the said variation | change_quantity. The information regarding the amount of change may be the amount of change itself or information corresponding to the amount of change / identifying the amount of change. In the embodiment, this change amount corresponds to a correction coefficient. By knowing the current amount of change, the user can immediately know how the amount of change has been changed and reflected depending on the current driving method and driving conditions. You can know if it will grow. Therefore, the user can take a driving operation with a larger amount of change. In addition, by notifying the user of the current change amount, it is possible to make the user motivate to maintain the state as it is or to make the change amount better.

  (4) The notification 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 method is preferable because the state of the current amount of change can be known at a glance according to its length. The display method of the display area is not limited to the indicator, and may be expressed by a numerical value or the like.

  (6) Moreover, the said alerting | reporting means is good to make it correspond to the information regarding the said variation | change_quantity the said character's appearance. The change in the appearance of the character may be a kind of reward that is more familiar to the user and more pleasing to the user as the amount of change is larger. The change in the appearance 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. Changes in facial expressions include, for example, “smiling” → “normal” → “looks lonely” → “moist” from the side with the largest amount of change. For example, the animation motion is increased or animated as the amount of change increases, or the animation motion is danced to express joy or fun. In addition, the smaller the amount of change, the smaller the movement, the movement does not move, or the depression. By utilizing the change in the character's appearance, the user can easily accept the current magnitude of the change, unlike the notification with an inorganic indicator or numerical value. And, for example, when the character has a sad face in a control state with a small amount of change, one of the factors that causes the user to drive in a control state with a large amount of change so as to make the character laugh. Become. The change in the appearance of the character may be performed independently, but it is preferable to link with the notification by the indicator or other display area. Since the display unit cannot be watched for a long time during driving, it may be easier to understand if the character's appearance changes as auxiliary information for notification in a display area such as an indicator.

  (7) The function for improving the relationship is to perform control so that the higher the degree of being with the machine, the better the function is. The function for controlling the change amount is actually based on information related to vehicle travel. It is preferable to perform control so as to change the amount of change different from the reference change amount that changes favorably depending on the degree with the machine.

  This machine is a device on which this system is mounted. The degree that the user has been with this machine is the degree that the user has been with this machine. The higher the degree that the user has been with this machine, for example, the stronger the connection between the user and the character, the greater the reliability from the character, and the relationship Since it can be estimated that it will become stronger, control is performed so that the higher the degree of compatibility with this machine, the better the relationship. The degree to which the machine is connected is determined based on, for example, travel distance, operation time, operation time, and various acquired driving situations. For example, in the case of mileage, control is performed so that the relationship becomes better as the total mileage becomes longer, and in the case of operation time, the relationship becomes better as the total time during which the machine is on is longer. Control is performed as follows.

  Assuming that the standard amount of change in which the degree of goodness or degree changes with the machine actually is the reference change amount, the function that controls the change amount is set to a change amount different from the reference change amount. The change in the degree of goodness and degree of relationship obtained by driving the vehicle may differ from the degree and degree of goodness of relation obtained based on the degree of actual relationship with the machine. Come out.

  (8) The function of controlling the amount of change is preferably to perform a positive assessment process that makes the change amount larger than the reference change amount and a negative assessment process that makes the change amount smaller than the reference process. . In this way, the relationship becomes so good that it cannot be obtained in normal driving, or the good growth of the relationship is bad. By driving in a positive assessment process, the degree of goodness of relation is increased in a short period of time, and character information corresponding to the degree is output. Therefore, even those who do not drive much can obtain better character information by paying attention to the driving operation, and even if the relationship is lowered due to some factor as described later, it will be related in a short period of time The degree and degree of goodness can be recovered.

  (9) The amount of change smaller than that of the reference process may include a negative value. In such a negative state, the control is performed such that the more the vehicle travels, the worse the relationship becomes compared to the current state. By providing such a negative value, the user will not perform a driving operation that will at least become a negative value. For example, when the driving is dangerous to a large extent or when the driving is not improved, the amount of change It is better to set it to a negative value, for example, by repeatedly performing a state / situation where becomes smaller.

  (10) The function of controlling the amount of change may be such that the amount of change is reduced when the acquired information relating to travel of the vehicle does not satisfy a set condition, and is returned to its original size after a predetermined period. The predetermined period is a set predetermined time, a period during which the vehicle has traveled a set predetermined distance, or the like. In order to return to the original size, for example, the reduced change amount may be gradually returned by a time constant or the like, or the reduced change amount may be maintained for a predetermined period and then returned at a stroke. When returning gradually, either continuous or stepwise may be used.

  In this way, if the change amount becomes small because the setting condition is not satisfied once, the state where the change amount is small is maintained for a predetermined period instead of immediately returning to the state where the setting condition is satisfied. For example, dangerous driving or traffic driving violations that are not desirable driving conditions may cause accidents or the like if they occur even for a short time or a short time. Therefore, even if it is momentary etc., since the user will keep in mind the driving | operation which does not stop satisfy | filling setting conditions, since it can contribute to safe driving etc. by setting conditions, it is preferable. Furthermore, if the setting condition is not satisfied even once, even if driving that satisfies the setting condition is not restored until a certain period of time elapses, there is a penalty and a game element may appear.

  (11) On the premise of the invention of (10) above, the function of controlling the amount of change increases the amount of change when the acquired information relating to traveling of the vehicle satisfies the set condition as the set condition is severe. Good.

  If the setting conditions are strict, there is a demerit that a small amount of change occurs for a certain period without satisfying the setting conditions due to a slight difference in driving operation, etc., but if the setting conditions are satisfied, the state where the amount of change remains large In addition, the degree and degree of good relationship increase in a short period of time, and various character information corresponding to the relationship can be obtained. Therefore, it becomes like a high risk / high return, and the game performance increases. In addition to simply improving gameplay, driving that satisfies more stringent setting conditions usually results in safer and more environmentally friendly driving conditions such as safe driving and eco driving. Often, it is also suitable for traffic environments.

  The amount of decrease in the amount of change when the setting condition is not satisfied may be constant regardless of whether the setting condition is severe, or may be varied depending on the difficulty of the setting condition. The control of the amount of change when the set condition is satisfied when there are a plurality of sets of information related to the traveling of the vehicle and the set condition is, for example, when the set condition of all the sets is satisfied, It is preferable to perform a control for reducing the amount of change when the total amount of increase of the amount of change set according to the degree of difficulty is not satisfied even when one setting condition is satisfied. Further, as another method of controlling the change amount, for example, for each set, an amount to be increased when the set condition is satisfied and an amount to be decreased when the set condition is not satisfied are set, and whether or not the set condition is satisfied is determined. Judgment may be made and the amount of change may be determined comprehensively, and various methods may be employed.

  (12) On the premise of the invention of (11) above, an input screen for designating relative multiple levels is displayed as an interface for inputting the setting condition, and for each level of the multiple levels of the input screen Thus, it is preferable to relate the set condition and the amount of change when the set condition is satisfied. The user only needs to specify a plurality of levels from “severe (difficult)” to “loose (easy)”, and can specify the setting conditions intuitively. Also, if the current setting condition often does not satisfy the condition, the setting condition is relaxed by one or more steps, and conversely, if the constant setting condition is satisfied, the setting condition is tightened by one or more steps. Thus, adjustments can be made to increase the amount of change, and appropriate conditions can be easily set.

  (13) Based on the inventions described in (10) to (12) above, the predetermined period may be set to zero immediately after the engine is started. By setting the predetermined period to 0, the standard change amount set immediately can be obtained. For example, if it is determined every unit time (for example, 1 second) whether or not the setting condition to be performed during traveling is satisfied, information regarding the traveling of the vehicle to be determined is acquired at least every unit time. Then, the determination process is performed. Therefore, usually, the determination during traveling is stored in a volatile storage unit such as a RAM, and a determination process is appropriately performed. Therefore, since the information about the travel of the vehicle immediately before the stop stored in the volatile storage unit when the engine is stopped (ignition off) is not retained, the information about the travel of the vehicle is not obtained immediately after the engine is started. May not meet. Therefore, even if the setting condition is not satisfied, it is possible to immediately return to the standard change amount by setting the predetermined period to 0.

  For example, when information related to vehicle travel is stored in the non-volatile storage unit, a determination process is performed based on information related to vehicle travel stored in the non-volatile storage unit immediately after startup, so the function of setting the predetermined period to 0 is Although it is not necessary to provide it, it is practical to update the information related to vehicle travel in a short cycle unit time as described above, because the upper limit of the number of rewritable times in the nonvolatile storage unit will be reached immediately. In addition, it is preferable because the problem immediately after the engine is started can be solved by a simple process of setting the predetermined period to 0.

  If the number of rewritable times in the non-volatile storage unit increases significantly, or if the vehicle's engine is stopped by installing a backup power source or the like, the information related to the running of the vehicle stored in the volatile storage unit will be retained 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 relating to traveling of the vehicle and setting conditions, and the setting conditions are set for each individual group. The plurality of sets may be different in both information relating to the traveling of the vehicle and the setting conditions, or may be common in one. For example, when 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 relating to the vehicle travel is one acceleration and the output of the sensor, but the output positive / negative is reversed. Therefore, the setting conditions are different and there are two sets. The same applies to detection of left and right sudden handle operations.

  For example, it can be easily met even under strict installation conditions depending on various usage conditions such as user's driving habits, vehicle characteristics, road conditions, installation position of this machine equipped with this system etc. There are cases where it is not possible. Therefore, by setting the setting conditions individually, it is possible to increase the amount of change while satisfying all the setting conditions.

  (15) The character information may be output in a stochastic manner, and the relationship may affect the probability. In this case, the probability that predetermined character information is output depends on the relationship, so that the game is more interesting.

  (16) On the premise of the invention of the above (15), it is preferable that the probability increases as the relationship becomes better. This is preferable because the user tries to improve the relationship. The increase in probability may be continuously increased according to an increase in the degree or degree of good relationship, or may be increased continuously for each predetermined range.

  (17) On the premise of the above inventions (15) and (16), the character information varies depending on the time zone, and the time zone includes a normal operation time zone and a non-normal (standby) operation time zone. Yes, it is preferable to output the character information in the normal operation time zone based on the probability in the non-normal operation time zone. The time zone may be divided into two, such as a day time zone and a night time zone, or may be further divided into three or more zones. For example, when divided into a daytime zone and a nighttime zone, the character sleeps at night, so the daytime zone is the normal operation time zone and character information corresponding to the relationship is output, but at night The time zone becomes a non-normal operation time zone, and a mode in which character information indicating a sleeping state is output regardless of the relationship can be taken. In the case of such an aspect, for users who drive mainly at night, the character information indicating the sleeping state is output, so it is not interesting. In such a case, the motion time zone may be set to be reversed between day and night, but the normal motion such as the output of character information based on the relationship even if the character wakes up by the probability and is in a non-normal motion time zone If you have a function to perform, it will be fun even more once because it works at night once. The game performance is further increased by associating the probability of operation with the relationship. In particular, it is preferable to increase the probability as the relationship becomes better because the user tries to improve the relationship.

  (18) If the set condition is satisfied, the character information may not be output until the return condition is satisfied. The return condition includes, for example, a fixed condition such as traveling for a fixed time or traveling for a fixed travel distance, and giving a predetermined item. The fixed time elapse may be, for example, the operating time of the present system or the elapsed time in the real world. If the character information is not output, the user cannot meet the character and is lonely. In addition, even if the character information is not output once, for example, when the standard condition is cleared, the character information is output again. By incorporating a mechanism in which character information is output under a special return condition, the user performs an action for getting an item, and the game performance is increased. For example, an item can be obtained by actually moving to a predetermined location, or by accessing a predetermined server / site and obtaining it for a fee or free of charge.

  (19) It is preferable to provide a function of performing control that deteriorates the relationship. As described above, the basic configuration of the present invention is to perform control to improve the relationship and control the amount of change to improve the relationship. The control that deteriorates the relationship includes, for example, a method in which the relationship is deteriorated all at once by directly deducting the degree or degree of good relationship. For example, if this deteriorating control is performed when the set deduction condition (predetermined speed over 3 times in succession) is satisfied, the relationship that has been accumulated so far will break down at once, so the user will We can expect to make efforts to prevent the situation from occurring. Therefore, the deduction condition is preferably set to match an operation or the like that is more undesirable than the condition for performing the control for reducing the amount of change. Further, 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 the deterioration control. In that case, the function of controlling the amount of change also serves as the function of performing control that deteriorates this relationship.

  (20) The function for controlling the amount of change may be controlled to increase the amount of change in the case of safe driving. (21) The function for controlling the amount of change may be controlled so as to reduce the amount of change when it is not safe driving. If it does in this way, safe driving can be recommended to a user.

  (22) The function of controlling the amount of change may be performed based on the operating state. Driving conditions include, for example, unfavorable driving conditions such as sudden acceleration (starting / running), sudden deceleration (stopping / running), sudden steering (rapid turning), and driving that is not ecological. is there. In particular, when an unfavorable operation state is detected, it is preferable to perform control to reduce the amount of change.

  (23) On the premise of the invention of (22) above, the driving state is a rapid acceleration (starting and running) obtained from acceleration in the traveling direction of the vehicle, and a sudden deceleration (when stopped) obtained from acceleration in the traveling direction of the vehicle. , During traveling), it may be at least one of the sudden changes in the traveling direction obtained from the acceleration in the direction crossing the traveling direction of the vehicle.

  (24) On the premise of the invention of the above (23), the sudden change in the traveling direction may be distinguished between right turn and left turn. For example, if the installation position of the means for detecting acceleration (for example, an acceleration sensor) (the installation position of this machine when it is built in this machine) is shifted to the right or left side of the vehicle, it turns at the same acceleration at the center of the vehicle. Even so, the acceleration value varies depending on the turning direction. Therefore, by changing the setting conditions according to the installation position, it is possible to open a trouble due to the difference in the installation position.

  (25) The function of controlling the amount of change may be such that the amount of change is reduced under certain conditions when a traffic violation occurs. In this way, the user can expect to drive while trying not to violate traffic.

  (26) On the premise of the invention of the above (25), the certain condition may be the same kind of violation at the same place. Examples of the same type of violations at the same location include a suspension violation at the same point and an overspeed at the same point. Repeating the same type multiple times in the same place is not careful and can be said to be worse than the first time, so the amount of change is reduced when repeated multiple times.

  (27) On the premise of the above inventions (25) and (26), it is preferable that the certain condition does not decrease the amount of change in the first violation. The first violation gives a grace without reducing the amount of change. As a result, the user's motivation is not lowered because the amount of change does not decrease, and attention can be given so as not to violate the next time. As a result, safe driving can be promoted. A warning should be given at the first violation.

  (28) On the premise of the above inventions (25) to (27), as a certain condition, the amount of change may be lowered by N or more violations. For example, in the case of a violation such as overspeed, it is difficult to immediately return to the speed limit or less even if the speed is noticed, and suddenly decelerating if the speed is made below the speed limit is dangerous. On the other hand, if the speed is continuously exceeded for a certain period, it can be estimated that there is no intention to decelerate and keep the speed limit, and it is a dangerous driving. Therefore, it is preferable to reduce the amount of change for the first time after N or more violations. At this time, a warning or the like may be given up to [N-1] times.

  (29) The degree to which the amount of change is decreased may be changed according to the degree of violation of the above (25) to (28). For example, even if the speed overrun is the same overspeed violation, the greater the overspeed from the speed limit, the greater the degree of danger and the more malicious. Therefore, it is better not to decrease the amount of change for the same overspeed violation, but to increase the amount of change to be reduced as the degree of violation increases. Here, changing the degree of decrease in the change amount may be, for example, changing the absolute amount when the change amount is once decreased according to the violation degree. For example, the greater the degree of violation, the greater the absolute amount when lowering. Further, as another example of changing the degree of decrease in the amount of change, the period required to return to the normal amount of change may be lengthened even if the amount of change in the amount of change upon violation is the same. For example, the greater the degree of violation, the longer the period required for return. As yet another example, the increase in the amount of change before returning to the normal amount of change may be delayed. These controls are preferably realized in combination.

  (30) On the premise of (29) above, the degree of violation is an excess speed exceeding the first reference speed, and if the second reference speed exceeding the first reference speed is exceeded, the excess speed is exceeded. It is better to lower the amount of change corresponding to The first reference speed may be a speed limit, for example, or a speed obtained by adding a predetermined margin (for example, 20 km / h) to the speed limit. And the 2nd standard speed is good to set it as the speed (exceeding 30 km / h), for example. An overspeed condition that results in a one-time waiver is a very dangerous driving condition that can lead to a major accident. In such driving conditions, the character's feeling that the character is assumed to have personality is very scary compared to, for example, a slight overspeed, and the intimacy and reliability for the user who is the driver are also reduced. There is. Therefore, when the second reference speed is exceeded, the amount of change is greatly reduced, that is, a very small value. By setting such a setting, on the contrary, the user will drive with care so as not to cause such a situation, and as a result, without driving excessively exceeding the second reference speed, safe driving is possible. Can be encouraged.

  (31) On the premise of (30) above, the first reference speed may be a speed obtained by adding a set speed to a speed limit. The set speed is preferably 20 km / h, for example. When driving according to the driving of surrounding vehicles, the speed limit may be exceeded without knowing it. In this case, if you are driving only with your own vehicle in compliance with the speed limit, it will lead to a dangerous situation, so by setting it so that the amount of change does not become small even if you exceed some speed, You can drive along the flow of surrounding vehicles.

  (32) In the case of an expressway having a speed limit less than a predetermined value, the first reference speed may be faster than a speed obtained by adding a set speed to the speed limit. The predetermined value may be a speed limit of a general highway such as 80 km / h. For example, the high speed may be 100 km / h.

  Generally, the speed limit on a highway is 80 km / h or 100 km / h. On the other hand, for example, there is a speed limit set to 60 km, which is lower than the speed limit of a general highway, such as the Metropolitan Expressway. A surrounding vehicle may travel at a speed similar to or close to the speed limit of a general highway (for example, 90 to 100 km / h). In such a case, it is important to observe the traffic rules. However, if only the host vehicle is traveling at a speed limit of 60 km / h, the speed difference from other vehicles may be 30 to 40 km / h, which is dangerous. Therefore, safe driving can be promoted by preventing the amount of change from becoming small even when traveling around.

  (33) On the premise of the invention described in (23) to (32) above, a warning is given that the amount of change will decrease if the next type of violation is made as a warning, and the next change if the same type of violation is made The amount should be reduced. Rather than suddenly lowering (aggravating) the amount of change, warning can prompt the user not to violate. When the same violation was made despite the warning, the advice from the character was ignored, and control was performed 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) On the premise of the inventions described in (23) to (33) above, it is preferable to restore the original change amount with a predetermined function (algorithm, rule) after lowering the change amount. (35) The predetermined function may delay the recovery as the degree of violation increases. The degree of violation includes, for example, the degree of violation in a single violation, such as the magnitude of excess speed, and the level of viciousness, such as repetition of the same violation at the same place. The higher the degree of violation, the worse the familiarity and reliability of the character user. Therefore, by delaying the recovery, the state where the change to the extent that the relationship becomes good lasts for a long time and the growth to the extent that the relationship becomes good becomes low. In addition, although it is not a traffic violation, such a state is also caused when control is performed in which the amount of change is reduced based on the driving state such as acceleration exceeding a threshold as in the inventions described in (22) to (24). If this is repeated, it is recommended to delay recovery. For example, if driving that is uncomfortable is performed repeatedly, the character's personality and feelings will be worsened, and the user will have a bad feeling, and it will take a long time to recover, so the original amount of change is restored. It is better to take longer time to do.

  (36) The function of controlling the amount of change may be performed based on the eco driving situation. The eco driving is obtained based on, for example, fuel consumption. For example, control is performed to increase the amount of change if the vehicle is eco-friendly and to reduce the amount of change if the vehicle is not eco-friendly. Also, if eco-driving, a positive assessment is performed to increase the amount of change, but if it is not eco-driving, the amount of change is not changed (no negative assessment is performed). Conversely, if it is eco-driving, the amount of change is not altered (plus assessment). If it is not eco-driving, a negative assessment may be made to reduce the amount of change. Eco-driving is economical because it consumes less fuel, is environmentally friendly, has less speed fluctuations, and is comfortable to ride, so if your character has personality, The feeling of joy is joy, and it can be said that the intimacy and reliability of the user are improved. Therefore, the amount of change was controlled based on the state of eco-driving.

  (37) An installation point of an item that affects the character's state may be set on a map, and when the vehicle goes to the location of the installation point, the item may be obtained with a certain probability. For example, the acquired item may be used to affect the state of the character, and the item may be stored. The state of the character affects the output of the character information, which may increase the game characteristics. A certain probability may be 100% (can be obtained without fail), or if there is a situation where the probability is not less than 100% (does not appear), the game performance may be further improved. This probability may be fixed depending on the whole or the type and location of each item, or may vary depending on the degree and degree of good relationship at that time.

As an item to get,
・ Improve the relationship (the relationship is up, bonus points, etc.)
・ Change does not decrease / goes up / returns to normal ・ Returns from disappeared state (appears on screen)
-The probability of the invention described in (15) etc. is increased. “Getting” may be, for example, a process for executing the above-exemplified process or a process for making the above-exemplified process executable according to the type of item. As a process for making the above-exemplified process executable according to the type of item, for example, a process for storing the type of the acquired item may be used. And you may make it perform the process regarding the kind of memorize | stored item at a predetermined timing.

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

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

  According to the present invention, it is possible to provide a system that can continuously encourage a driver to drive safely by maintaining a strong emotional transfer of the driver to the character. Moreover, the character information that is output is in accordance with the relationship with the character, and in order to control the amount of change when the relationship is satisfactorily changed based on the information related to the traveling of the vehicle, Even if the degree of presence with this machine is the same, different character information is output if the vehicle travels differently. Therefore, since the character information output by the user changes depending on how the user's vehicle is driven, the game performance is also increased. Further, it is possible to urge the user to perform a control such that the amount of change is increased.

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

"Basic configuration of electronic equipment"
1 and 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 includes a case body 2 having a thin rectangular shape, and is fixed on a dashboard of a vehicle by using a bracket 3 attached to the lower side of the back side of the case body 2.

  A display unit 5 is provided on the front surface of the case body 2 (the surface facing the vehicle rear side (driver side)). The display unit 5 is composed of a 3.2 inch color dot matrix TFT liquid crystal display. On the display unit 5, a touch panel 6 for detecting which part of the display unit 5 is touched is provided. A volume adjustment button 7 is disposed on the right side of the front surface of the case body 2, and various work 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 detachable recording medium, and a memory card reader 10 is built 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 takes in data stored in the attached 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), and the update information is transmitted via the control unit 18. The data is stored (downloaded) in the database 19 built in the apparatus, and the data is updated.

  The database 19 can be realized by a nonvolatile memory (for example, EEPROM) in the microcomputer of the control unit 18 or externally attached to the microcomputer. Further, the memory card 11 itself may be configured as a part or all of the database 19. The database 19 stores map data and information related to a certain alarm target at the time of shipment, and data and the like regarding the alarm target added thereafter are updated as described above.

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

  An 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 the acceleration applied to the traveling direction of the X-axis, the acceleration applied to the Y-axis in the horizontal direction, and the acceleration applied to the Z-axis in the vertical direction. As a result, the X-axis detects sudden acceleration / deceleration, the Y-axis detects a sudden handle, and the Z-axis detects a predetermined behavior of the vehicle such as climbing a step or falling into a depression.

  The case body 2 has an OBD adapter 21 that is detachably attached to an OBD-II (II is a Roman numeral “2”, hereinafter “OBD-II” will be referred to as “OBD2”). Is connected. The OBD2 connector is also referred to as a failure diagnosis connector, and is connected to the ECU of the vehicle to periodically output various vehicle information. Therefore, the controller 18 periodically acquires various types of vehicle information by connecting the OBD adapter 21 and the OBD2 connector on the vehicle body side.

  The vehicle information includes vehicle speed, injection injection time, intake air amount, remaining fuel information, and the like. The remaining fuel is the amount of fuel remaining in the current fuel tank and is output with a resolution of 0.5 liters. Therefore, by acquiring the remaining fuel periodically and recording the timing of the change between the previous remaining fuel and the current remaining fuel, it is consumed after the previous change occurs until the current change occurs. It can be said that the amount of fuel is 0.5 liters. In addition, there is also information that periodically outputs information on fuel consumption (information on lifetime fuel consumption, current fuel consumption, instantaneous fuel consumption, etc.).

  The OBD adapter 21 is detachably linked to a connection terminal 23 provided on the case body 2. When the vehicle information from the OBD2 connector is unnecessary, removing the OBD adapter 21 can suppress the wiring from being scattered on the dashboard or the like, and can make the surroundings of the radar detector clear.

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

  The functions of the radar detector 1 according to the present embodiment are stored in the EEPROM of the control unit 18 as firmware executed by the CPU included in the control unit 18, and are realized by being executed by the CPU included in the control unit 18. The firmware stored in the EEPROM can be updated with 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 promoting safety to the driver. The alarm information is output in the following cases, for example. The control unit 18 obtains the distance between the target position (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 is less than the predetermined distance, alarm information is output from the output device. 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 speed measurement device. The radar detector 1 makes a driver recognize a dangerous place where a traffic accident is likely to occur by outputting alarm information. Thereby, the radar detector 1 can prompt the driver to drive safely. Note that the alarm information described above is an example, and actually, various other alarm information is output to the driver.

(Display mode)
FIG. 3 shows a 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 includes a radar standby display mode, an OBD display mode, and a MAP display mode as the normal 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 vehicle tilt state, a screen showing the acceleration applied to the vehicle, etc. 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, expressway average fuel consumption, engine speed, engine load factor, throttle opening, etc. In this mode, the screen shown in FIG. The MAP display mode is a mode for displaying a map in the vicinity of the vehicle on the display unit 5 (see FIGS. 7 to 9). The display mode is switched based on 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 that is a display mode when alarm information is output will be described. In the radar standby display mode and the OBD display mode, a telop indicating alarm information is displayed on a screen corresponding to each of the constant display modes, and a warning sound is output from the speaker 16. In contrast, in the MAP display mode, the alarm information output mode can be switched to an animation mode, a live-action mode (hereinafter collectively referred to as a non-character mode), and a character mode. In response to the pressing of the lower work button 8, the control unit 18 switches between the character mode and the non-character mode alternately. As shown in FIG. 7, in the animation mode, the control unit 18 displays the target object and the animation 101 of the speed measurement device superimposed on the map 100 and outputs a warning sound from the speaker 16. As shown in FIG. 8, in the live-action mode, the control unit 18 superimposes and displays the target object and the real-shot (REALPHOT) 102 of the speed measurement device on the map 100 as alarm information, 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 displays the character 104 so as to overlap the map 100. Further, the control unit 18 outputs the voice of the character 104 from the speaker 16. Warning information is notified to the driver by the behavior and voice of the character 104.

  The radar detector 1 as a driving support system in the present embodiment is characterized by an operation in a character mode (within a thick frame line 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 when it is not necessary to notify the driver of 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 the behavior and voice according to the familiarity that is an example of the relationship with the driver. As a result, the radar detector 1 guides the driver to strongly empathize with the character 104. Furthermore, the character 104 outputs not only a notice of a dangerous place where a traffic accident is likely to occur, but also alerts for dangerous driving, rough driving, driving lacking concentration, and dozing driving as alarm information. The driver who wants to deepen the degree of emotion transfer to the character 104 will respond positively to the alert from the character and actively try to drive safely. Radar detector 1 prevents the driver from getting bored of communication with the character by developing and maintaining the level of emotional transfer of the driver to the character at a high level, and continues safe driving for the driver Can be encouraged.

  Note that the above display modes (always display mode and alarm display mode) are examples, 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 the storage unit 19)

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 is based on information input from the input device, and when the vehicle state or driving state is determined to be a predetermined state (hereinafter referred to as an event occurrence), the driver is notified of various events. This is information output from the output device for performing. The standby information is information output from the output device in a state where no event has occurred (hereinafter referred to as a standby state).

  The map information is information for displaying the map 100 on the display unit 5 and includes information on the target object, traffic rule information, and the like in addition to normal map data such as a road network. The information regarding 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 live action displayed on the display unit 5, and sound output from the speaker 16 are associated with each other. Target targets include fixed speed measurement devices (including speed measurement devices that emit radar waves (microwaves) such as radar and speed measurement devices that do not emit radar waves such as loop coils), snooze driving accident points, radar, Speed limit switching point, control area, inspection area, parking monitoring area, N system, traffic monitoring system, intersection monitoring point, signal ignorance suppression system, police station, accident-prone area, on-vehicle frequent occurrence area, sudden / continuous curve ( Expressway), branch / merge point (expressway), ETC lane advance guidance (expressway), service area (expressway), parking area (expressway), highway oasis (expressway), smart interchange (expressway), PA / SA Gas station (highway), tunnel (highway), highway radio reception area (high speed) Road), prefectural border notice, roadside station, viewpoint parking.

The information regarding the speed limit is information that specifies 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 and a road type (highway / general road).

  The setting information is information indicating various operating 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.

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

  The correction information is various pieces of information for correcting the actual travel distance to obtain the corrected total travel distance. The correction information includes a correction coefficient, a travel distance for a predetermined period, and the like. The correction coefficient is a coefficient for obtaining a corrected total travel distance for obtaining the familiarity described later. The correction coefficient is obtained by the control unit 18 based on information related to vehicle travel. 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 change history of the vehicle position coordinates and the correction coefficient described above. The corrected total travel distance can also be said to be a virtual total travel distance based on travel in the virtual space with respect to the travel distance in the real space.

  Intimacy is an index indicating the degree of relationship with a character. Character information is output corresponding to the level of closeness. As the intimacy increases, character information such as a reward that the driver who is the user wants is output. Pay attention to the distance traveled by the user as a radar detector and therefore the character, and the longer the distance traveled, the higher the degree of being together and the better the relationship between the driver and the character, that is, the closeness control Based on. This is because when the total travel distance increases, the driver has driven for a long time with the character for a long time, and the relationship becomes better. In the present invention, for example, the intimacy corresponding to the total travel distance is not uniquely specified such that if the actual total travel distance exceeds a set threshold, the intimacy also increases by one step. The amount of change when changing the relationship based on the increase in mileage is changed. That is, the familiarity is obtained based on the corrected total travel distance obtained based on the correction coefficient described above. By appropriately controlling and determining the correction coefficient, the corrected total travel distance can be made longer or shorter than the actual total travel distance. Details will be described later.

  The surrounding information is information about the target object around the current position of the vehicle. Information on the target object includes information indicating the type of the target object and the distance between the current position and the target object.

OBD information includes fuel consumption, fuel flow, vehicle speed, coolant temperature, engine speed, throttle opening, and the like. The control unit 18 turns on the event flag when an event occurs.

  As shown in FIG. 11B, in addition to programs such as firmware, the EEPROM stores the corrected total travel distance up to the previous engine stop, the driver's violation status, and the like. As described above, the corrected total travel distance is stored in the RAM as described above when the engine is running and the radar detector 1 is operating. Then, the corrected total travel distance at that time stored in the RAM when the engine is stopped is stored and held in the EEPROM. Violation status information is information about violations that occurred during driving. The control unit 18 stores the violation content, the violation occurrence location, and the number of times in association with each other.

(Function of control unit)
12 to 16 are flowcharts showing functions of the control unit 18. The main process starts when the control unit 18 executes the firmware stored in the EEPROM. 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 an operation to turn on the power is not detected (S11: NO), the process returns to S11. When detecting an operation of turning on the power, the control unit 18 activates a fixed cycle process which is an interrupt process activated at a predetermined cycle (S13). As the periodic process starts, the control unit 18 reads out the corrected total travel distance stored in the EEPROM, and stores the read out corrected total travel distance in the RAM.

(Periodic processing)
When starting the periodic processing in S13 (see FIG. 12), the control unit 18 repeatedly executes the periodic processing at a constant cycle (for example, every second). That is, the control unit 18 executes the main process and the fixed period process in parallel. This periodic 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 specifies the current date and time based on the date and time data included in the received GPS signal, and stores the specified 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 part 18 performs the process (target position specification process: refer FIG. 14) which specifies the position of the target object which exists around the vehicle (S37).

  This target position specifying process is as shown in FIG. That is, first, the control unit 18 specifies coordinate information indicating the position of the vehicle based on the GPS signal received from the GPS satellite via the GPS receiver 13. 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 or not there is a target object in the vicinity of the coordinate information indicating the position of the vehicle specified in S51 (for example, within 2 km from the current position of the vehicle). (S53). When there is a target object in the vicinity of the vehicle (S53: YES), the control unit 18 associates the type of the target object and the distance between the target object and the vehicle, and stores them in the RAM as peripheral information (S55).

  When the target object is not in the vicinity of the vehicle, or after executing the process S55, the control unit 18 has a signal corresponding to a microwave in a frequency band emitted from a speed measuring device that emits a radar wave such as a mobile radar. The signal is received via the microwave receiver 14. In addition, the control unit 18 includes a control radio, a car radio, a digital radio, a special radio, a jurisdiction radio, a police phone, a police activity radio, a tow radio, a heli tele radio, a fire helicopter radio, a fire fight radio, an emergency radio, and an expressway radio. The frequency of police radio, etc. (hereinafter collectively referred to as “car location radio”) is scanned. Then, when there is a radio signal at the scanned frequency, the control unit 18 receives the signal via the radio receiver 15 (S57).

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

* Calculation of corrected total travel distance, etc. After the above-described target position specifying process (FIG. 13: S37) is completed, the control unit 18 calculates a corrected total travel distance, and stores the calculated corrected total travel distance in the RAM (S39). ). That is, the control unit 18 updates the storage area of the corrected total travel distance in the RAM. Specifically, the control unit 18 is based on the history of changes in vehicle position coordinates stored in the RAM, from the execution of the previous fixed cycle process to the execution of the current fixed cycle process (for example, for 1 second). The travel distance and the current correction coefficient are obtained. The control part 18 calculates | requires the correction | amendment driving distance in the execution cycle (for example, 1 second) of a fixed period process by a following formula.

Correction travel distance = Correction coefficient × Travel distance

  And the control part 18 calculates | requires the correction | amendment total travel distance which took into consideration this travel amount by adding the calculated | required travel distance and the correction total travel distance until now memorize | stored in RAM, and calculated | required correction | amendment total travel Record the distance in RAM. The control unit 18 stores the obtained correction coefficient in the RAM as one piece of correction information.

  As shown in the equation for obtaining the corrected travel distance, when the correction coefficient is 1, the actual travel distance and the corrected travel distance are equal (see “solid line” in FIG. 17A). Thus, for example, the corrected travel distance required when actually traveling 1000 km is 1000 km. On the other hand, when the correction coefficient is larger than 1, the corrected travel distance becomes longer than the actual travel distance (see “dashed line” in FIG. 17A). When the correction coefficient is smaller than 1, the actual travel distance is actually The corrected travel distance is shorter than the travel distance (see “dashed line” in FIG. 17A).

The correction coefficient may be determined based on the sensor output value (acceleration) of the acceleration sensor 22, for example. For example, the correction coefficient in the normal state where the acceleration is equal to or less than the set threshold value 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 value. Thereafter, when the normal state continues for a certain period, control is performed so that the original normal correction coefficient is restored. 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 a predetermined period (FIG. 17B). reference). Specifically, the control unit 18 calculates a correction coefficient based on the following equation.

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

Here, m is a normal correction coefficient (value where the asymptote converges)
L is the distance traveled after the acceleration exceeds the threshold (actual distance traveled) Unit is meter d is 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 in the RAM. Each time the control unit 18 executes the periodic processing, that is, based on the history of changes in the vehicle position coordinates stored in the RAM every second, from the execution of the previous periodic processing to the execution of the current periodic processing. Is calculated (for example, for 1 second). The control unit 18 reads the travel distance for a predetermined period stored in the correction information storage area of the RAM, and adds the travel distance for the current time obtained above to obtain the value of L. The control unit 18 calculates the correction coefficient by substituting it into the above equation using the obtained L value and the m and d values stored as the RAM correction information. In addition, the control unit 18 updates the travel distance for a predetermined period stored in the correction information storage area of the RAM to the L value obtained this time.

  When the acceleration exceeds the threshold value, L is reset to 0, so the correction coefficient once becomes 0, and the correction coefficient increases as L increases. When “mL” becomes sufficiently larger than “d”, d in the denominator in the equation for obtaining the correction coefficient can be ignored, so that the correction coefficient is m, that is, the normal time correction coefficient.

  Further, since the L value is stored in the correction information storage area of the RAM, the stored data is erased when the engine is stopped, and the L value is reset to 0 when the engine is turned on. Therefore, when the engine is turned on, the value of d is set to 10 so that the value of L is sufficiently larger than d immediately after the start of running so that the correction coefficient is immediately the normal correction coefficient m. Yes. On the other hand, after the acceleration exceeds the threshold and the correction coefficient once becomes 0, the value of d is increased (for example, 100) so that it takes time to return to the normal correction coefficient.

  In the present embodiment, sudden acceleration / deceleration and sudden handle (right sudden handle / left sudden handle) can be detected individually based on the output of the acceleration sensor. 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 where the acceleration exceeds the threshold value falls into one of sudden acceleration / deceleration and sudden steering, which is not only dangerous driving, but also makes it uncomfortable for the character who is riding the vehicle. Also not mentally good. Therefore, in the present embodiment, when the driving is performed such that the acceleration exceeds the threshold value, the correction coefficient is decreased so that the closeness is less likely to increase, and the normal correction coefficient is not restored for a certain period. ing.

  As described above, in this embodiment, when the setting condition (here, the acceleration threshold value) is not satisfied once and the correction coefficient becomes small, the predetermined condition is not immediately restored even if the setting condition is satisfied immediately thereafter. The period was maintained with a small correction coefficient. For example, a non-preferable driving state such as a dangerous driving in which the acceleration exceeds a threshold value may cause an accident or the like if it occurs instantaneously or for a short time. Therefore, the driver is conscious of driving that does not fail to satisfy the set condition even if it is instantaneous, etc., which is preferable because it can contribute to safe driving or the like depending on the set condition. Furthermore, if the setting condition is not satisfied even once, even if driving that satisfies the setting condition is not restored until a certain period of time elapses, there is a penalty and a game element may appear.

  As will be described later, the increase in the corrected total travel distance is related to the increase in intimacy. Therefore, if the degree of increase in familiarity based on the actual increase in travel distance, that is, the amount of change in which familiarity increases when the correction coefficient is 1, is referred to as “reference change amount”, the reference coefficient increases as the correction coefficient becomes larger than 1. The amount of change is larger than the amount of change, and the smaller the correction coefficient is, the smaller the amount of change in the familiarity that accompanies the traveling becomes smaller than the reference amount of change, and the lower the elongation.

  When the normal correction coefficient is set to a value larger than 1, the driving is continued so that the acceleration does not exceed the threshold value, so that the degree of change in intimacy accompanying running is greater than the reference amount of change. It is possible to maintain a high degree of intimacy with a short mileage.

  The value of the normal correction coefficient is set to be larger as the threshold value is smaller, for example. In other words, if the threshold value is small, the sensitivity becomes high and there is a high possibility that even if a small speed change (relatively small acceleration) exceeds the threshold value and L is reset to 0, if the vehicle can travel below the threshold value, the total correction will be completed in a shorter period Travel distance can be increased and intimacy can be increased. On the other hand, when the threshold value is large, the sensitivity is low, and even if there is a slight speed change (relatively large acceleration), the threshold value is not exceeded, so that the correction coefficient is lower than the normal correction coefficient over a certain period due to L being reset to 0 However, even if the vehicle is traveling below the threshold value, the correction factor for normal operation is originally small, so that the increase in the corrected total travel distance is low. Therefore, the user may set a threshold value according to his / her driving situation, road condition, and the like.

  If the setting condition (threshold) is tightened, there is a demerit that a small correction coefficient value occurs for a certain period without satisfying the setting condition due to a slight mistake in driving operation, etc., or if the setting condition is satisfied, the correction coefficient The state of large is continued, the degree and degree of goodness of the relationship rises in a short period of time, and various character information corresponding to the relationship can be obtained. Therefore, it becomes like a high risk / high return, and the game performance increases. In addition to simply improving gameplay, driving that satisfies more stringent setting conditions usually results in safer and more environmentally friendly driving conditions such as safe driving and eco driving. Often, it is also suitable for traffic environments.

  For this setting, for example, a combination of threshold values in each detection direction corresponding to a plurality of levels of sensitivity and information relating the correction coefficient of the level are stored in the database 19. For example, for the standard level, a threshold value is set for each acceleration sensor output for detecting sudden acceleration / deceleration, right sudden handle / left sudden handle, and 1 is associated as a correction coefficient. A level that is more sensitive than the standard level is set to a threshold smaller than the threshold associated with the standard level, while the correction coefficient is set to a value larger than 1. Conversely, a level that is less sensitive than the standard level is set to a threshold value that is greater than the threshold value associated with the standard level, while the correction coefficient is set to a value that is less than one. Prepare one or more sensitive and insensitive levels. The control unit 18 reads a predetermined setting screen from the database 19 and displays it 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 familiarity The control unit 18 identifies familiarity based on the corrected total travel distance (S40). The familiarity is a parameter 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 as the corrected total travel distance of the vehicle increases, and represents the degree of intimacy as intimacy. Specifically, the intimacy 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 first activated, the familiarity is zero. When the total travel distance of the vehicle with the character mode set is 100 km or more and less than 1000 km, the familiarity is 1. In addition, when the total travel distance of the vehicle with the character mode set is 1000 km or more and less than 2000 km, the familiarity is 2. Further, when the total travel distance of the vehicle in the state where the character mode is set is 2000 km or more, the familiarity is 3. The control unit 18 stores the obtained familiarity in the RAM.

  This familiarity is an index indicating the degree of relationship with the character, and becomes a larger value as the relationship is better. In the present embodiment, the familiarity level is increased in four stages such as 0 → 1 → 2 → 3. The familiarity is a condition for determining character information output via an output device as will be described later. The better the relationship, that is, the greater the familiarity value, the more the character information that is output will be in the form of a kind of reward that flies to variations, is more familiar to the user, and makes the user happy. .

  Control for improving the relationship, that is, information for increasing the intimacy, is based on the travel distance. In principle, the longer the travel distance, the higher the familiarity. For example, if it is estimated that the character has personality / emotion, the relationship between the driver and the character increases as the distance traveled with the character increases. Thus, for example, if the mechanism is such that the relationship becomes better as the vehicle is driven safely, the user can maintain a good relationship with the character and the degree of goodness can be further increased. At the same time, we will actively try to drive safely.

(Specification of driving conditions, etc.)
Next, the control part 18 performs the process (a driving | running state specific process, refer FIG. 15) which specifies the driving information of a vehicle (S41). As shown in FIG. 15, the control unit 18 acquires the vehicle speed from among the acceleration detected by the acceleration sensor and the OBD information stored in the RAM (S71). Next, the control unit 18 determines whether or not the vehicle is in a predetermined driving state based on the acquired acceleration and vehicle speed (S73). Specifically, the control unit 18 includes (a) meandering operation, (b) sudden deceleration, (c) sudden acceleration, (d) right sudden handle, (e) left sudden handle, (f) concentration reduction operation, (G) It is determined on the basis of the acceleration and the vehicle speed whether the vehicle is driven in any driving state of the dozing operation. The determination method is as follows.

  Number of occurrences of each state in which the vehicle's forward acceleration is 0.3G or more, the vehicle's backward acceleration is 0.15G or more, and the vehicle's lateral acceleration is 0.45G or more When the condition that the total is generated 15 times or more in 15 minutes is satisfied, the control unit 18 determines that (a) the meandering operation is performed. Moreover, the control part 18 judges that the rapid deceleration was performed when the acceleration of the front direction of a vehicle became 0.3 G or more (b). The control unit 18 determines that the rapid acceleration has been performed when the acceleration in the rearward direction of the vehicle is 1.15 G or more (c). When the acceleration in the left direction of the vehicle becomes 0.45 G or more, the control unit 18 determines that (d) the sudden right steering is performed. When the acceleration in the right direction of the vehicle becomes equal to or greater than 0.45 G, the control unit 18 determines that the sudden left steering wheel is performed (e). When the vehicle speed is 55 km / h or more and the change width of the vehicle speed is continuously 5 km / h or more and less than 10 km / h for a predetermined time or longer, the control unit 18 performs (f) concentration reduction operation. It is judged that 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) the snoozing operation is 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.

  When the controller 18 corresponds to any of the above and determines that the vehicle is being driven in a predetermined driving state (S73: YES), the control unit 18 stores information indicating the corresponding driving state in the RAM as a driving state ( S75). And the driving | running state specific process is complete | finished and a process returns to a fixed cycle process. On the other hand, when the operating state does not correspond to any of the above (S73: NO), the controller 18 ends the operating state specifying process, and the process returns to the regular cycle process.

  As shown in FIG. 13, after the operation state specifying process (S39) ends, the control unit 18 stores the peripheral information in the RAM in S55 (see FIG. 14) and S61 (see FIG. 14) or S75 (see FIG. 13). In FIG. 15), it is determined whether or not the operation state is stored in the RAM. When any one is memorize | stored in RAM, the control part 18 judges that the event for performing a notification to a driver | operator generate | occur | produced (S43: YES). The control unit 18 turns on the event flag (S45). The periodic processing ends. On the other hand, if neither the peripheral 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 starting 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 information corresponding to the set display mode from the output information of the database 19 and outputs the output device. Output from. Thereby, the control part 18 performs well-known normal operation | movement operation | movement (warning alerting | reporting etc.) (S21). The process proceeds to 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 of notifying the driver of predetermined information via the character (character mode process, FIG. 16). (S19).

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

  The control unit 18 determines whether or not the current date and time has already been specified in the periodic processing started in S13 (see FIG. 12) and the information is stored in the RAM (S85). In periodic processing, the current date and time, vehicle position information, and travel distance are specified by receiving GPS signals that are radio signals from GPS satellites. Depending on the radio wave environment, GPS signals may not be received immediately after startup. is there. Therefore, the time required to specify the current date and time is not constant and may take time. If the current date is not stored in the RAM, the current date has not been specified yet (S83: NO).

  In this case, the control unit 18 displays the wallpaper screen 73 on which the character 104 is lying on the display unit 5 as shown in FIG. 18 (S85). If the current date and time are not specified, the calculation of the travel distance and therefore the corrected total travel distance to the specification of the intimacy cannot be performed. The process returns to S83. Thereby, the control unit 18 continues to display the wallpaper screen 73 until the current date and time are specified. The current date and time etc. include a history of vehicle position information other than the current date and time. However, if the current date and time are stored in the RAM, a GPS signal can be received. May be based.

  When the current date and time, vehicle position information, and the like are specified in the periodic processing and the information is stored in the RAM (S83: YES), the control unit 18 reads out still image information stored in the database 19 and displays the display unit 5 (S86). As a result, for example, as shown in FIG. 19, a still screen 72 showing a state in which the character 104 is dressed up is displayed on the display unit 5. Note that the still screen information includes a total of 12 still screens that differ from month to month. Seasonal scenes are reflected on each still screen. When reading the still screen, the control unit 18 extracts the current month from the current date and time information, selects the still screen of the month corresponding to the extracted current month from the still screen information stored in the database 19, and displays the display unit. 5 is displayed.

  As described above, the radar detector 1 switches the still screen displayed on the display unit 5 according to the date and time, thereby suppressing the driver from getting bored with the still screen. Further, the radar detector 1 makes the driver feel that he wants to see a new still screen. Here, for example, the control unit 18 may perform control so that a new still screen is not displayed on the display unit 5 when the driver performs dangerous driving or the like. Accordingly, the driver tries to drive safely in order to display a new still image on the display unit 5. In this way, the radar detector 1 can effectively guide the driver to 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 activation screen included in the activation information stored in the database 19 and displays it on the display unit 5 (S87). Moreover, the control part 18 reads the starting audio | voice contained in starting information, and outputs it from the speaker 16 (S87).

  The activation information will be described in detail with reference to FIG. 20 and FIG. The activation information is information that is output to the output device during activation in the MAP display mode-character mode. As illustrated in FIG. 20, the activation information includes information for displaying a character image on the display unit 5 (hereinafter referred to as a character image), and information for outputting a character voice from the speaker 16 (hereinafter referred to as a character image). , Called character voice). The character image and the character sound are intimate (0-3) and time zone (0: 00-5: 00, 5: 00-7: 00, 7: 00-10: 00, 10: 00-17: 00, 17:00 to 22:00, 22: 0 to 0:00). The time zone indicates the time when the radar detector 1 is turned on. A plurality of character images and character voices are prepared for each intimacy and time zone so that the character can communicate with the driver in various ways of expression.

  FIG. 21 shows in detail the character voice corresponding to the time zone 7:00 to 10:00. If the familiarity stored in RAM is 1, "Good morning. How are you?" "Now, work hard. I will do my best." "Good morning. Drive safely today. "Please give me a comment". The expression mode of the character with respect to the driver is the first face-to-face mode. On the other hand, if the intimacy is 2, “Good morning. How are you?” “Every day, it ’s not just fun, but do your best.” “Oh, yes, drive carefully today.” In addition, the character voice is more intimate than when the familiarity is 1. The expression mode of the character for the driver is a normal friend mode. Furthermore, if the intimacy is 3, "Oh! Hey, I've been waiting for you since I woke up" "Wow! I can stay with you today ~ I'm happy" "Good morning! Today is fashionable "I want new clothes, I want to do it". The expression mode of the character with respect to the driver becomes a mode of friendship.

  As described above, the radar detector 1 increases the intimacy of the character with respect to the driver according to the intimacy by outputting the intimate character voice as the intimacy increases. The driver feels that the intimacy of the character is gradually increasing, so that the familiarity with the character is gradually increased and emotions are strongly transferred to the character.

  Although not shown in the figure, the character voices in the time zone from 5:00 to 7:00 are compared for each familiarity. If your intimacy is 1, you can hear character voices like “Good morning ぅ ~ Fah ~ I ’m sorry.” “Good morning. I'll do my best today.” It has become. When the intimacy is 2, the character sound is like the character sound of “That? Is it already in the morning?” “It ’s not good enough! Furthermore, if the intimacy is 3, "Ohayo ~ wa ~~, sorry." "Ooh ~ yeah, I'm still sleepy .. 1 minute." "Good morning. Character sound like “ The driver feels as if the character is a living creature by listening to the sleepy voice of the character. In addition, the driver feels sorry for being awakened by the character. The radar detector 1 further increases the degree of emotion transfer to the driver's character by causing the user to have such emotions.

  In the above description, the example in which the character voice is switched every activation time has been described. However, the character image is also switched every activation time. For example, a time zone of 0:00 to 5:00 is associated with a character image in an expression mode in which the character is sleeping on a bed. The driver feels close to the character by watching the character go to bed. The radar detector 1 further increases the degree of emotion transfer to the driver's character by causing the driver to have such emotions.

  As described above, the radar detector 1 switches and outputs the character voice for each activation time zone as if the character is a real creature. Thus, the driver feels as if the character actually exists. In this way, the radar detector 1 can increase the degree of emotion transfer to the driver character. In addition, the output character information has contents such as a kind of reward that flies to variations as the intimacy increases, and that makes the driver easy to get familiar with and happy with the driver. Accordingly, the driver is strongly motivated to perform the operation and driving so as to maintain a good relationship so as to receive a reward or to improve the relationship. Therefore, it can be expected that the driver performs driving that increases the intimacy. That is, in this embodiment, the increase in intimacy is not only a simple increase in travel distance, but also the amount of change with respect to a predetermined travel distance changes based on information related to vehicle travel, for example, whether or not acceleration exceeds a threshold value. Control is performed, and the control is performed such that when the acceleration exceeding the set threshold is applied to the vehicle, the increase in the corrected total travel distance for determining the familiarity over a certain period is reduced. Therefore, the driver tries to travel such that the acceleration detected by the acceleration sensor 22 is equal to or less than the set threshold value. Therefore, the radar detector 1 of this system contributes to safe driving.

  Furthermore, in order to increase the intimacy, that is, the corrected total travel distance, it is not necessary to simply extend the travel distance, and information regarding the travel of the vehicle (acceleration in the present embodiment) is also considered. For example, if the correction coefficient never exceeds 0 during driving, the correction total travel distance can be earned and a sense of clearing the mission is obtained, which is preferable. Clearing such a mission is not just a game in a virtual space, but a game with a new sensation that occurs with actual driving. Even if the actual driving of the vehicle has game characteristics, the mission is cleared by driving safely so as not to change the speed (increase / decrease speed) or make a sudden change of direction so that the acceleration value is below the threshold value. Because there is a need, there is no problem in social wisdom. The same applies to the output of character information based on the familiarity shown below.

  In the activation information of FIG. 20, character voice is not associated with familiarity: 0. When the familiarity is 0, the radar detector 1 displays the character image on the display unit 5 and does not output the character sound from the speaker 16. In this case, the driver recognizes not only the character image but also the character voice, and inflates the expectation that he wants to start intimate communication with the character early. The radar detector 1 uses the driver's psychology to increase the degree of emotional transfer to the driver's character.

  As shown in FIG. 16, after outputting the activation information (S87), the control unit 18 reads the character information from the standby information in 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 a 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 character voice. Character images and character voices are classified according to intimacy. In FIG. 22, “familiarity 1-3” indicates that different character images and character voices are associated with the respective familiarities.

  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 and the character voice corresponding to the expression modes of (1) blink & mouth pack, (2) blink only, (3) walk, and (4) stretched back are included in the character information. ing. For example, when a character image corresponding to (1) blinking & mouth-packing is displayed on the display unit 5, the character blinks and moves his mouth as if he is scolding something. Further, for example, (3) when a character image corresponding to a walk is displayed on the display unit 5, the character freely walks around in the display area of the display unit 5. Further, for example, (4) when a character image corresponding to the back stretch is displayed on the display unit 5, the character stretches back. Further, the character voice corresponding to each expression mode is output from the speaker 16.

  FIG. 23 shows in detail the character voice corresponding to (1) blink & mouth-pack. If your intimacy is 1, you say, “Do you like driving? I do n’t hate your driving.” “Thank you for bringing me to your car!” A friendly character voice is associated. On the other hand, if your intimacy is 2, you said, “Did you like me, I love you too!” “When you drive, you look pretty serious. In this way, a closer character voice is associated with the intimacy than when the familiarity is 1. Furthermore, if the intimacy is 3, intimacy like "I'm happy every day because you're talking!" "I really want to talk more. I want to know more about you." Compared with the cases of 1 and 2, more intimate character voices are associated. When the character voice is output from the speaker 16, one of a plurality of character voices associated with the familiarity: 1, 2, and 3 is randomly selected and output. Therefore, even in a situation where the intimacy is the same, a different character voice is output from the speaker 16 each time.

  As described above, the radar detector 1 increases the intimacy of the character with respect to the driver according to the intimacy by outputting the intimate character voice as the intimacy increases. When the driver feels that the character's intimacy with respect to himself / herself is gradually increasing, the familiarity with the character gradually increases and emotions are strongly transferred to the character.

  The radar detector 1 always displays the character on the display unit 5 and outputs the character voice from the speaker 16 so that the character speaks to the driver even in a standby state where no event occurs. As a result, the driving support system 4 makes the driver feel as if the character is a living creature and always beside him. Since the driver has a sense of familiarity with the character, the degree of emotional transfer of the driver to the character is further increased.

  Furthermore, the radar detector 1 prepares a plurality of character images and character voices, selects them at random, and outputs them from the 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 familiarity: 0, and the character voice is not associated. Therefore, when the familiarity 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 cannot hear the character voice when the intimacy is low, the driver expects to recognize not only the character image but also the voice. The radar detector 1 uses the driver's psychology to increase the degree of emotion transfer to the driver's character.

  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 for the control unit 18 to output the character information (see FIG. 24, described later)? Is determined (S93). The character information is information output to the 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 output information will be described later. If it is determined that it is time 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, if the control unit 18 determines that it is not the timing to output the character information (S93: NO), the process proceeds to S97.

  A method for determining whether or not to output character information in the event information and the character information to be output are as follows. FIG. 24 shows the details of the character information in the event information. The character information includes a character image and 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 while sleeping, (4) attention to overspeed, (5) get sick, (6) sudden deceleration, (7) sudden Acceleration, (8) Steep right handle, (9) Steep left handle, (10) Angry, disappear after 10 degrees, (11) Relieve, return, (12) Nap, (13) Awake, (14) Concentration reduction, (15) Doze driving, (16) Orbis, crackdown, check alarm, (17) Radar, car location reception alarm, and (18) Other character images and voices corresponding to the target object are familiarity: 1 -3. Note that, as with 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 the 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 sound from the speaker 16.

  For example, the character information corresponding to “(1) going to bed” is information that is 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 the timing when one minute has passed after the radar detector 1 is activated. The control unit 18 uses the voice to inform the driver of bedtime as information indicating this bedtime (“Today was fun, take a drive again tomorrow.” “I will sleep. “Good night” is selected according to the familiarity, and is output from the speaker 16 as character voice. The control unit 18 periodically outputs the character's sleep as a character voice from the speaker 16 after going to bed.

  For example, the character information corresponding to “(2) get up” is information that is 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 the timing when one minute has passed after the radar detector 1 is activated. The control unit 18 uses the voice to inform the driver of the wake-up as information indicating the time of the wake-up (“Good morning. Alarm resumes Mars”, “Good morning. I can be with you today! I ’m happy!”) Is selected according to the familiarity, and is output from the speaker 16 as character voice.

  For example, the character information corresponding to “(3) sleeping while sleeping” is information that is randomly output in a period of 5 minutes in a period of 10 minutes to 30 minutes when the character is sleeping. When the character image is displayed on the display unit 5 as information representing the sleeping sleep while sleeping, the control unit 18 performs an animation of moving the mouth of the character. In addition, the control unit 18 selects sleeping words (“starry beautiful.” “Re, regular full, please ぅ” etc.) according to the familiarity, and at the timing when the character moves the mouth, It outputs from the speaker 16 as a character voice.

  As described above, in this system, character information is output in an expression manner as if the character is a real creature. The driver feels as if the character actually exists. In this way, the present system can increase the degree of emotion transfer to the driver's character.

  For example, the character information corresponding to “(4) Attention to overspeed” is information that is 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 a speed limit of a road that is currently running or a speed limit of an installation position of a speed measuring device existing 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 indicating that the speed is excessive when the vehicle speed is higher. When the character image is displayed on the display unit 5 as information indicating the warning of overspeed, the control unit 18 notifies the driver of the current vehicle speed and the speed limit, for example, so as to decelerate. An animation that prompts In addition, the control unit 18 responds to the intimacy with a voice to notify that the speed is exceeded ("Hey ~! Isn't it out of speed? It's dangerous ~", "Hey, I hate those who overspeed!") Are selected and output from the speaker 16 as character voice. Thus, the driver can easily recognize that the traveling speed of the vehicle exceeds the speed limit. Since the driver's degree of emotion transfer to the character is strong, the driver pays attention to safe driving by slowing down in response to the notification from the character.

  For example, the character information corresponding to “(5) Car sickness” is output when the event flag stored in the RAM is ON and information indicating the meandering driving is stored as the driving state. . This is because in such a case, there is a high possibility that the vehicle is traveling on a road with continuous curves.

  When the character image is displayed on the display unit 5, the control unit 18 outputs an animation that behaves as if the character feels sick due to car sickness. In addition, the control unit 18 transmits the voice that seems to be painful to the character (such as “I ’m sorry, I ’m sorry,” “I ’m already drunk because I ’m driving like that.”) The selection is made according to the density, and the sound is output from the speaker 16 as character voice. As a result, the driver feels sorry for the character's car sickness and tries to drive carefully with reduced speed. In this way, the present system can prompt the driver to drive carefully.

  For example, in the character information corresponding to “(6) sudden deceleration, (7) sudden acceleration, (8) right sudden handle, (9) left sudden handle”, the event flag stored in the RAM is ON, and driving is performed. This information is output when information indicating sudden deceleration, rapid acceleration, right sudden handle, and left sudden handle is stored as the state. This is because when the driver drives with these driving methods, the vehicle is more likely to cause a traffic accident. 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 depends on the detected acceleration direction. Also voice to notify the driving method (rapid deceleration: "Cheer! I was about to fall. I'll get angry next time?" "Did you drive in front of it properly? ---------- I hit my head! I saw it !? “I'm not going to start suddenly! Do n’t do it anymore?” “Hey, did you make a mistake with the brakes and the accelerator?” : "Keep your handle a little more slowly-my eyes will turn around" "Kyaaah I've seen it before? I thought it would fall down." According to the selection, the character voice is output from the speaker 16. This makes the driver aware that he is driving wildly and dangerously, and he tries to drive carefully. By giving a warning in this way, the present system can prevent a traffic accident from occurring.

  For example, in the character information corresponding to “(16) Orbis, enforcement, check alarm”, the event flag stored in the RAM is turned on, and the radar type Orbis, H system, LH system, and loop coil (hereinafter referred to as these) When the information indicating the distance between Orbis and the vehicle is a predetermined distance (for example, 2100 m, 1100 m, and 600 m), the information indicating “Obis” is collectively stored in the RAM as peripheral information. Is output. Alternatively, it is output when the event flag 38 stored in the RAM is ON and information indicating a control or an inspection 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 turned ON, and information indicating the speed measuring device or the emergency vehicle for police is stored in the RAM as peripheral information. Output if stored.

  Character images corresponding to these “(16) Orbis, enforcement, inspection warning” or “(17) Radar, car location reception warning” are 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. Note that the clothes of the character before the transformation and the character after the transformation, the animation operation, and the like may be changed in accordance with the priority.

  The transformed character 104 is displayed overlaid on the display screen of the map 100 on which the peripheral target object 105 is shown as shown in FIG. 27, and as shown in FIG. 28, Orvis, enforcement, inspection, speed measuring device, and Information 74 indicating any one of the police emergency cars and a distance 75 between the vehicles are provided to the driver. In addition, voices for notifying the driver of the display contents ("Emergency, radar orvis discovered 2000 meters away." "Thousands of meters approached! Radar type Orbis!" Is not selected "is selected according to the familiarity, and is output from the speaker 16 as a character voice.

  As described above, the radar detector 1 as the driving support system can recognize that the target object whose traffic is to be monitored is near the vehicle by receiving the radio signal transmitted from the target object. Traffic monitoring devices are often installed in places where traffic accidents are likely to occur or where accidents have occurred in the past. Therefore, the radar detector 1 informs the driver that the target object to be monitored for traffic is near the vehicle, so that the driver can recognize a place where a traffic accident is likely to occur. Can encourage you to keep in mind.

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

Further, since the driver is notified by the character voice that the distance between the object whose traffic is to be monitored and the vehicle is approaching, even if the driver does not look at the display unit 5, the radar The detector 1 can make the driver surely recognize that the vehicle is approaching the Orvis or the like.
In addition, although specific description is abbreviate | omitted, the character information according to familiarity is output also about another expression mode.

  As shown in FIG. 16, the control unit 18 determines whether or not a setting operation on the radar detector 1 by the driver has been detected (S97). 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 a setting operation (S <b> 97: YES). Based on the setting screen information stored in the database 19, the setting screen is displayed on the display unit 5. 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). As the control unit 18 executes processing based on the setting information, the radar detector 1 operates as set by the driver. The process proceeds to S101. On the other hand, when the setting operation by the driver is not detected (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 terminated, 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.

(Variation with indicator)
FIG. 29 is an example of a display screen showing a modification 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, a 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. In the correction coefficient display area 81, an indicator that the light emitting area expands and contracts in the vertical direction is used. The indicator shown in the figure is such that the approximate center position in the vertical direction of the correction coefficient display area 81 is “0” and extends upward as the correction coefficient value increases. The maximum value is 4 here. Further, as will be described in another modification described later, when the correction coefficient takes a negative value, the indicator light emission area has a display mode that extends downward from the center position where the correction coefficient value is 0. That is, the indicator takes a form as shown in a schematic diagram as shown in FIG.

  In particular, when the correction coefficient can take a negative value, for example, in both “1” and “−1”, the length of the light emitting region is the same and the length is short, and the center in the vertical direction is short. Because it is located in the vicinity, it is difficult to understand which value is at a glance. In particular, the traveling driver cannot keep an eye on the display unit 5 for a long time, needs to check the display contents of the map 100 and the character 104 in a short time, and displays the correction coefficient display area 81. Combined with the fact that the area itself is small, it becomes more difficult to recognize the current correction coefficient.

  Therefore, the emission color was 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 system such as blue or light blue, and when the correction coefficient is a negative value, the display color is displayed in a warm color system such as red or pink. In this way, even if a short light emitting area is displayed near the center in the vertical direction, the driver is negative in whether the current correction coefficient is positive and decent in that color. Intuitively understand whether the situation is very bad. Also, red means “stop” for traffic lights and often means prohibition even for traffic signs, while blue means “progress” for traffic lights and traffic signs are not particularly prohibited. A driver who knows that can see that red is not desirable in a reflective manner.

  The control unit 18 operates as follows in order to execute the correction coefficient notification function using such an indicator. The control unit 18 periodically reads out the correction coefficient stored in the RAM, and displays an indicator so that a light emitting 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. 29A, the light emitting area portion of the indicator is displayed in blue.

  Although it is the timing and period of reading, it is preferable to set a short time (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 operation is being performed correctly. And if the light emitting area of the indicator disappears when the accelerator pedal or brake pedal is depressed, or when the steering wheel is turned by turning right or left or changing course, the driver exceeds the threshold and the correction coefficient becomes zero It is also possible to know the fact that the correction coefficient has become 0 based on the previous driving situation. Therefore, you can understand your driving habits (easy to start suddenly / easy to step on brakes / easy to handle suddenly, etc.). Measures can be taken to drive without lowering. Further, once the correction coefficient becomes 0, the correction coefficient gradually increases and returns to the normal correction coefficient as shown in FIG. 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 able to confirm such a state and to continue driving while paying attention so that the acceleration does not exceed the threshold value.

  On the other hand, if the average of a long period etc. is taken, it will be difficult to show said effect. That is, even if the correction coefficient is reduced to 0, the state does not appear immediately, and the driver cannot understand which driving operation has exceeded the threshold value, or is buried by the previous high correction coefficient. It may be difficult to recognize that the correction coefficient did not drop to 0 and safe driving was not performed. Furthermore, even if the correction coefficient drops once, when the indicator display is updated next time, it may return to its original state, and the state of gradually returning may not be recognized.

  Moreover, although it is the update period of this indicator, it is good to match | combine with the period of a fixed period process. This is because the current correction coefficient can be known because the correction coefficient is updated each time the periodic processing is executed and affects the corrected travel distance. This indicator display processing may be performed in parallel with the periodic processing or may be performed as the periodic processing.

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

  Therefore, since the current correction coefficient is notified using the correction coefficient display area 81 (for example, an indicator) as in this modification, the driver can know the current correction coefficient, You can immediately see how the amount of change changes and is reflected by the driving conditions. Therefore, the driver can know, for example, what kind of driving operation the correction coefficient becomes small or large. As a result, the driver can take a driving operation in which the correction coefficient does not decrease or increases. In addition, by notifying the driver of the current correction coefficient, the driver can be motivated to maintain the state as it is or to improve the correction coefficient.

  In this modification, the current correction coefficient is reported using an indicator, but the present invention is not limited to this. For example, the present correction coefficient is not limited to this value. It may be expressed indirectly by a method.

  Further, the current correction coefficient notification may be made not by the correction coefficient itself but by changing the character appearance according to the correction coefficient. Although specific illustration is omitted, for example, the facial expression of the character may be changed. As an example of this change, “smiling” → “normal” → “looks lonely” → “moist” may be used, and the degree of smile may be further divided into a plurality of stages. Also, if it is difficult to understand with just facial expressions, add animation. In any case, it is preferable that the character information corresponding to the character having a larger correction coefficient has a certain kind of reward that is more familiar to the user and makes the user happy. The correction coefficient notification function using the character appearance may be executed alone or in combination with other notifications such as an indicator.

(Modification example with acceleration change setting function)
In the embodiment described above, the normal correction coefficient value is set to be larger as the threshold value is smaller and smaller as the threshold value is larger. In this setting, a combination of a predetermined threshold value and a set of normal correction coefficients are selected by designating “sensitive-standard-insensitive”. On the other hand, in this modification, threshold values (detection sensitivity) can be individually set for each of the four accelerations for detecting sudden acceleration / deceleration and right / left sudden handle.

  Specifically, the control unit 18 uses internal data (FIGS. 30A and 30B) and an input screen (FIG. 30C) that is an interface for inputting setting conditions as shown in FIG. 30A is a table in which the sensitivity shown in FIG. 30A as internal data is associated with the threshold values of acceleration for combinations of four detection targets of sudden acceleration / deceleration, right sudden handle / left sudden handle, and FIG. In this example, the sensitivity shown in (b) and the asymptotic line values associated with the combinations of the four detection targets are associated with each of the six sensitivity levels. Is divided into four sensitivity levels, and the database 19 stores screen information having a matrix structure shown in FIG.

  For example, when the control unit 18 detects 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 it is detected 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 it on the display unit 5. The button area of the current setting condition is displayed in a different color from the other button areas. In the illustrated example, the sensitivity of sudden acceleration and sudden deceleration is set to 4, and the sensitivity of the right sudden handle and the left sudden handle is set to 3.

  Each button area specified by the sensitivity and the four detection targets in the setting screen is set in an area corresponding to the acceleration sensor threshold value (FIG. 30A) and the asymptotic line value (FIG. 30B). Associated with a number. For example, taking the current selection state as an example, the acceleration acceleration threshold 4 is associated with an acceleration sensor threshold value of 0.4 and an asymptote value of 0.2. Similarly, the sudden deceleration sensitivity 4 is associated with the acceleration sensor threshold of 0.4 and the asymptotic line value of 0.2, and the left and right steering handle sensitivity 3 is asymptotic with the acceleration sensor threshold of 0.5. The line value is associated with 0.3. Under this setting condition, if either of the longitudinal accelerations exceeds the threshold (0.4), the correction coefficient becomes 0, and if the lateral acceleration exceeds either of the thresholds (0.5), The correction coefficient becomes zero. In other words, when all the accelerations in the four directions do not exceed the corresponding threshold values, the set normal correction coefficient is maintained. The normal correction coefficient is the sum of the asymptotic line values. That is, in this example, the normal correction coefficient 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 corrected total travel distance are the same increase amount.

  On the other hand, in the present modification, the sensitivity can be individually set for the four detection targets. Therefore, for example, when it is detected that the button area that is insensitive to rapid acceleration (for example, 2) is touched, the control unit 18 The acceleration sensor threshold value shown in 30 (a) and the asymptotic line value data shown in FIG. 30 (b) are accessed, and the acceleration sensor threshold value (0.5) associated with the sensitivity 2 of the sudden acceleration touched is asymptotic. The line value (0.1) is acquired and set in the corresponding area of the RAM. Then, since the acceleration threshold for sudden acceleration has been 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 normal correction coefficient is 0.9, so that the corrected travel distance becomes shorter than the travel distance even if the driving does not exceed the threshold, and the distance does not increase. On the other hand, when the sensitivity of the right sharp handle is increased to 4 from the state shown in FIG. 30, the control unit 18 accesses the internal data in the same manner as described above, and updates the threshold value asymptotic line values stored in the RAM. Then, since the threshold value is reduced from 0.5 to 0.45, the possibility that the threshold value will be exceeded is high, but if driving that does not exceed the threshold value is continued, the correction coefficient becomes 1.1 and the corrected travel distance rather than the actual travel distance Is bigger. If each asymptote is set as shown in FIG. 30B, the normal correction coefficient is 1.8 at the maximum and 0.2 at the minimum.

  Since the input interface to be displayed to the driver is an input screen for designating relative levels of each sensitivity as shown in FIG. 30 (c), the internal data shown in FIGS. 30 (a) and 30 (b). Even if specific numerical values (threshold value or asymptote line value) are changed, the input screen viewed by the driver does not need to be changed. Therefore, since the user interface does not change, the operability can be kept good. Then, the driver only needs to specify a plurality of levels from “strict (difficult)” to “loose (easy)”, and can set the setting conditions intuitively. Also, if the current setting condition often does not satisfy the condition, the setting condition is relaxed by one or more steps, and conversely, if the constant setting condition is satisfied, the setting condition is tightened by one or more steps. Thus, adjustments can be made to increase the amount of change, and appropriate conditions can be easily set.

  Since the threshold can be individually set in this way, the driver sets the threshold in such a combination that a high score (high normal correction coefficient) can be obtained while driving in which the acceleration in any direction does not exceed the threshold. it can.

  For example, it can be easily met even under strict installation conditions depending on various usage conditions such as user's driving habits, vehicle characteristics, road conditions, installation position of this machine equipped with this system etc. There are cases where it is not possible. Therefore, by setting the setting conditions individually, it is possible to increase the normal correction coefficient while satisfying all the set conditions for the four detection targets. As a driving habit, a driver who does not change the speed very much but makes a sudden lane change is sensitive to sudden acceleration and sudden deceleration (for example, 5 or 6), and insensitive to left and right sudden steering ( For example, 1) is set.

  In addition, as for the characteristics of the vehicle, for example, in the case of a manual vehicle, it tends to start suddenly, so detection of sudden acceleration is made insensitive, and others are made standard or sensitive. More specifically, if the installation position of the acceleration sensor 22 in the vehicle is more central than the installation position of the radar detector 1, the sensitivity of the left and right sudden handles is the same, but the installation position is left and right. If it is shifted to either, the lateral force related to the acceleration sensor is different between the right turn and the left turn. Therefore, it is preferable to make one sensitivity sensitive and the other sensitivity insensitive.

(Modification for restoring the correction coefficient: using the distance constant d in particular)
In the embodiment described above, the distance constant d is set to 10 when the engine is ON. However, when adopting a configuration in which the distance traveled up to that point is stored even when the engine is turned off, L is a predetermined large value from the time the engine is turned on, so it is not necessary to take a measure of setting it to 10.

  Moreover, although it is a fixed value when acceleration exceeds a threshold value and L is reset to 0, in the above-described embodiment, one type of fixed value (for example, 100) is used. As the distance increases, the distance constant d should be increased. For example, d after exceeding the first threshold value is 100, the second time is 500, the third time is 1000, the fourth time is 5000, the fifth time is 10,000. By changing d, the violation is repeated, and if it is malicious, the period (here, the travel distance) required to return to the normal correction coefficient also takes longer. In this way, the greater the number of times the acceleration exceeds the threshold value, the longer the travel distance required to return to the normal correction coefficient, the lower the correction coefficient over a longer time, and the increased (increased) corrected total travel distance. Change amount). Therefore, once the driver has driven the acceleration exceeding the threshold value, it can be expected that the driver will drive while taking care not to exceed the acceleration.

  This means that when the acceleration exceeds a threshold value, for example, a character who is also a passenger has a feeling of being tired or feeling uncomfortable and feeling down. When such a state is repeatedly performed, the user's feelings when the character is given personality / emotion is also deteriorated, and it takes a long time to correct the mood. Increasing d above also shows a change in the morals of the character.

  In the above-described embodiment and this modification, the travel distance required to return to the normal correction coefficient is determined by d, and the correction coefficient gradually increases according to a predetermined function until the travel distance is reached. I made it. The present invention is not limited to this, and may be stepwise and discretely increased, or a predetermined correction period with a low correction coefficient that decreases during a predetermined period (for example, traveling a certain distance). You may make it return to a normal time correction coefficient at a stretch after progress. The fixed travel distance may be fixed, or may be increased as the number of times the acceleration exceeds the threshold increases as in the present modification.

(Modification Example of Adjustment of Correction Coefficient 1: Adjustment with Excessive Speed 1)
In the above-described embodiment, acceleration is used as information associated with the traveling of the vehicle that performs a negative assessment to reduce the correction coefficient. However, in this embodiment, the vehicle speed is further added to one of the conditions. Specifically, if you are driving at a speed exceeding the speed limit while driving at a point where a speed limit is set, a negative assessment to reduce the correction coefficient is made because it is a traffic speed limit speed violation. Do. In this case, the speed limit is often slightly exceeded, and it is dangerous to keep the speed limit against the flow of the surrounding cars. Therefore, in this modified example, the first reference speed that is a criterion for determining whether or not the speed is exceeded is set not to the speed limit itself but to a speed higher than the speed limit by a set speed. In other words, if the current vehicle speed exceeds the first reference speed, a negative assessment is made to reduce the correction coefficient.If the current vehicle speed is below the first reference speed even if the speed limit is exceeded, the negative assessment accompanying the overspeed is not Not performed. The set speed may be set to 20 km / h, for example. For example, an overspeed of about several km / h is likely to occur as the vehicle goes downhill or the speed of surrounding vehicles is increased overall. And when the surrounding vehicles are traveling at a speed exceeding the speed limit as a whole, if only the host vehicle is traveling in compliance with the speed limit, a dangerous state will be caused. In view of this, it is possible to drive according to the flow of the surrounding vehicle by setting the control so that negative assessment control to the correction coefficient does not occur even if the speed is slightly exceeded. On the other hand, speeds exceeding 20 km / h are less likely to cause such circumstances and increase the degree of danger. This is a criterion for increasing the degree of danger because if the speed limit exceeds 20 km / h, the number of violation points at the time of traffic violation becomes two. Therefore, a negative assessment was performed at a set speed of 20 km / h.

Further, in the control for reducing the correction coefficient based on the acceleration, when the threshold value is exceeded, the correction coefficient is uniformly reduced to a predetermined value (for example, 0) regardless of the value of the correction coefficient at that time and the degree of exceeding the threshold value. However, the adjustment control accompanying the overspeed in this modified example changes the effect of reducing the correction coefficient in accordance with the magnitude of the overspeed. It can be said that overspeeding is the same as overspeeding violation, but the danger increases as the overspeeding speed from the speed limit increases. Therefore, the greater the degree of violation (excess speed), the lower the effect of the reduction in the correction coefficient, that is, the rate of increase in the corrected total travel distance associated with actual travel. Specifically, the control unit 18 acquires the current position information of the vehicle stored in the RAM, acquires the speed limit set for the current position from the map information stored in the database 19, and the first reference Find the speed (limit speed + set speed). Further, the control unit 18 acquires the vehicle speed from the OBD information recorded in the RAM, and determines whether or not the vehicle speed exceeds the first reference speed. When the first reference speed is exceeded, the control unit 18 calculates a 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 a normal correction coefficient (value where the asymptote converges)
L is the distance traveled after the acceleration exceeds the threshold (actual distance traveled) Unit is meter d is distance constant
(When the engine is on: 10
After reaction by acceleration sensor: fixed value greater than 10 eg 100)
k is a speed coefficient (for example, 0.0025)
v is the overspeed (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 in the basic embodiment described above.
Correction coefficient = (m ^ 2 * L) / (mL + d) (2)

  For example, when the vehicle is traveling at 81 km / h at a point where the speed limit is set to 60 km / h, the first reference speed is exceeded, so the correction coefficient is obtained using the above equation (1). In this case, since the excess speed v is 1 km / h, the value of M is “k− (m / 1000)”. Further, when traveling at the same point at 85 km / h, the excess speed 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 almost 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, the tendency that the absolute value of M increases as the excess speed v increases although the absolute value is smaller than M as in the above-described embodiment is the same.

  Since the correction coefficient takes a negative value, if the vehicle travels exceeding the first reference speed, the corrected total travel distance decreases as the vehicle travels. Then, since the correction coefficient is obtained in consideration of the excess speed v, when the excess speed v is 5 km / h rather than 1 km / h, the degree of decrease in the corrected total travel distance when traveling the same distance becomes larger. Since the value of M increases exponentially with respect to the magnitude of the excess speed, the larger the excess speed, the greater the penalty.

  On the other hand, for example, when the vehicle speed is 70 km / h, since the vehicle speed is equal to or lower than the first reference speed, the control unit 18 obtains the correction coefficient based on the above equation (2). Since this correction coefficient takes a positive value, the corrected total travel distance associated with traveling at a speed always increases. Therefore, the driver tries to drive below the first reference speed in order to prevent the correction coefficient from becoming negative.

  Moreover, in said modification, 20 km / h was shown as an example of setting speed. This set speed may be a fixed value or may be switched according to another condition. Another condition is, for example, a speed limit on an expressway. Since a normal highway has a speed limit of 80 km / h or 100 km / h, the first reference speed in such a case may be 100 km / h or 120 km / h. On the other hand, on a highway 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.

  In some cases, for example, the speed limit is 60 km, which is slower than the speed limit of a general highway, such as the Metropolitan Expressway. On such an expressway with a slow speed limit, surrounding vehicles may travel at a speed similar to or close to that of a general expressway (for example, 90 to 100 km / h). In such a case, it is important to observe the traffic rules. However, if only the host vehicle is traveling at a speed limit of 60 km / h, the speed difference from other vehicles may be 30 to 40 km / h, which is dangerous. Therefore, safe driving can be promoted by preventing negative assessment based on excessive speed even when traveling around.

(Modification 2 of adjustment of correction coefficient: Adjustment accompanying suspension violation)
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 the suspension is violated, the control unit 18 obtains a correction coefficient by subtracting a predetermined value from the current correction coefficient. Since the predetermined value is subtracted, the obtained correction coefficient may be negative. Furthermore, when the suspension violation is performed several times at the same point, the predetermined value to be subtracted is increased. Repeating the same type multiple times in the same place is not careful and it can be said that the violation is worse than the first time. The increase in the corrected total mileage accompanying the increase in the distance was made worse. In this way, the user can expect to drive while trying not to violate traffic.

  Furthermore, in the first suspension violation, a grace period is given without subtracting the correction coefficient although it warns. As a result, since the correction coefficient does not decrease at the first violation, the driver's motivation is not lowered, attention can be given not to violate the next, and safe driving can be promoted as a result. Also, as a warning in the case of the first violation, for example, immediately after making a suspension violation, voice information such as “I didn't stop now. If you go to the place afterwards, it may be possible to output a warning from the speaker 16 in front of the speaker, for example, such as “I didn't stop last time, please stop now”. The voice warning message to be output may be changed according to the intimacy.

  If you violate the suspension in this way, instead of immediately reducing the correction factor from the first time, you will be warned that if you violate the same type next time, you will notice that the correction factor will decrease. It is advisable to lower the coefficient. Instead of suddenly lowering the correction coefficient, a warning can be issued to prompt 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 the current position information from the vehicle position coordinates stored in the RAM, accesses the 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 position. The determination as to whether or not the vehicle has been maintained is performed based on whether or not the state where the vehicle speed is 0 continues for a plurality of cycles since the periodic processing is performed every second.

  If it has not been paused, the control unit 18 searches the violation status stored in the EEPROM to determine whether there is a pause violation for the same location. The location information and the number of violations (1) of the place where the temporary stop has not occurred are stored. If there is a record of a violation of suspension at the same location, the number of violations associated therewith is read and incremented by 1, and 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 (1 for the first time, 1 if the previous violation history has been read, a value obtained by incrementing the number of violations read from the EEPROM by 1), and calculates the correction coefficient based on the following equation: Ask.

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

Here, m is a normal correction coefficient (value where the asymptote converges)
L is the distance traveled after the acceleration exceeds the threshold (actual distance traveled) Unit is meter d is distance constant
(When the engine is on: 10
After reaction by acceleration sensor: fixed value greater than 10 eg 100)

s is the temporary deduction factor The number of violations at the same location: 1st time: 0
Number of violations at the same place 2nd time: 0.5
Number of violations at the same place 3rd time: 1
Number of violations at the same place more than 4 times: 2
τ is the mood recovery time constant 600 (The mood recovers completely in 10 minutes)
t is the elapsed time since the suspension violation (seconds)

  In the above formula, the first term is the control of the correction coefficient based on the same acceleration as in the embodiment, and the second term is the deduction control due to the violation of the temporary stop. In the case of the first violation, no points are deducted because the temporary deduction coefficient s is 0. Since t is 0 when the suspension is violated, the suspension deduction coefficient s is subtracted from the current correction coefficient. As the number of times increases, the pause deduction coefficient s increases, so that the correction coefficient is also greatly subtracted to a smaller value. For example, even if the normal correction coefficient is 1 or 1.2, the correction coefficient becomes negative at a stroke because the suspension deduction coefficient s is 2 after the fourth violation in the same place. Even if the number of violations at the same place is the third time, if the normal correction coefficient is set to a low value such as 0.8, the correction coefficient becomes a negative value. Furthermore, even if it is the second time, etc., if the suspension is violated in a section where the correction coefficient is small in 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 tries to stop properly at the place where the vehicle is temporarily stopped, so that the driver can drive safely.

  Note that the period during which the deduction due to the suspension violation is affected is defined by the elapsed time τ. As can be seen from the second term, in this modification, t = τ is fixed at 600 seconds = 10 minutes, but τ may be changed depending on the number of violations. For example, the second time may be 10 minutes for recovery, the third time may be 30 minutes for recovery, and the fourth time may be 60 minutes for recovery.

(Modification 3 of adjustment of correction coefficient: Adjustment due to excessive speed 2)
In the first modification, when the first reference speed is exceeded, the correction coefficient takes a negative value. Therefore, when the vehicle is traveling at the first reference speed or lower, the correction coefficient drops to a negative value at once when the correction coefficient is a positive value but exceeds the first reference speed even at 1 km / h. On the other hand, in the third modification, control is performed to reduce the correction coefficient when the first reference speed is exceeded, but a positive value is set. As control for reducing the correction coefficient within a positive range, for example, L in the expression for calculating the correction coefficient in the above-described embodiment (formula (2) in the deformability 1) is set to an appropriate value 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. However, in the case of a deduction due to overspeed, the correction coefficient restarts from the value of the correction coefficient corresponding to L corresponding to the overspeed v, and gradually. Will increase. Further, a deduction point due to excessive speed may be separately provided, such as deduction due to temporary stop in Modification 2.

  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 reduced from the extent that Should be lowered significantly. In this case, for example, the second reference speed may be set to a speed at which a single departure / exemption is allowed (exceeding 30 km per hour). An overspeed condition that results in a one-time waiver is a very dangerous driving condition that can lead to a major accident. In such an operating state, the correction coefficient should be greatly reduced, that is, a very small value (for example, a negative value). With this setting, on the contrary, the driver will drive with care so as not to cause such a situation, and as a result, there will be no excessive speed exceeding the above set speed, and safe driving Can be encouraged.

(Modified example with control function to worsen relationship (intimacy))
In the embodiment and each modification described above, the value of the correction coefficient is controlled to affect the increase in the intimacy indicating the relationship, but in this modification, the relationship is deteriorated. As a function to perform control, it has a control function that greatly reduces or deducts the corrected total travel distance that is directly linked to the determination of intimacy. If this deteriorating control is performed when the set deduction conditions are met, the relationship that has been accumulated so far will be destroyed at a stretch, so the user should strive to prevent such a situation from occurring. Can be expected.

  The degree of penalty may be much greater than control of the correction coefficient based on overspeed exceeding the first reference speed, and this deduction condition is more serious. Taking speed over as an example, for example, it may be a case where a third reference speed that is faster than the first reference speed is exceeded. The third reference speed may be, for example, 30 km / h higher than the speed limit at which a single departure / pause is allowed. An overspeed condition that results in a one-time waiver is a very dangerous driving condition that can lead to a major accident. In such a driving state, it is very scary to assume that the character has a personality as compared with a slight overspeed, and it can be predicted that the intimacy / reliability with respect to the user who is the driver also decreases. Therefore, the corrected total travel distance is greatly reduced. The distance to be lowered is set to an excessive amount such as, for example, 1000 km unit. On the contrary, the user will drive with care not to cause such a situation, and as a result, the excessive speed exceeding the above set speed is exceeded. It is possible to promote safe driving without any problems. In addition, as an example of the third reference speed (over 30 km / h), the same speed as the second reference speed shown in the above-described modification 3 is shown, but the specific speed may be the same or different. good. Set appropriately according to the purpose.

  Further, as a deduction condition for greatly reducing the corrected total travel distance, the violation is performed N times or more (for example, three consecutive times). For example, in the case of violations such as overspeed, it is difficult to immediately return to below the speed limit even if you notice an overspeed, and it is dangerous to suddenly decelerate in order to suddenly go below the speed limit. is there. On the other hand, if the speed is continuously exceeded for a certain period, it can be estimated that there is no intention to decelerate and keep the speed limit, and it is a dangerous driving.

  At this time, a warning by voice or the like is given up to [N-1] times. As a warning, for example, a notice is given that the next time the same type of violation is made, the reliability will be lowered, and when the same type of violation is continued, the corrected total traveling distance caused by the familiarity is greatly reduced. It is possible to prompt the user to decrease the speed by warning instead of suddenly decreasing. 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 the vehicle speed included in the OBD information in the RAM (for example, 1 second), and determines whether the third reference speed is exceeded. If the speed is equal to or lower than the third reference speed, the current determination ends. When the third reference speed is exceeded, the control unit 18 gives a first warning. Thereafter, it is continuously determined whether the third reference speed is exceeded. If the vehicle speed falls below the third reference speed even during continuous monitoring, it is assumed that this series of overspeed conditions has been resolved. After that, if the vehicle speed exceeds the third reference speed, the first warning is given again. In addition, when the state where the third reference speed is exceeded continues for a certain time (for example, 3 minutes), the control unit 18 gives a second warning. The control unit 18 then continues to obtain the vehicle speed periodically and compares it with the third reference speed. Then, if the vehicle speed becomes the third reference speed or less even once, it is assumed that this series of overspeed conditions has been resolved. Therefore, when the vehicle speed subsequently exceeds the third reference speed, the control unit 18 gives a first warning again. On the other hand, when the state exceeding the third reference speed continues for a certain time (for example, 3 minutes) after the second warning, the control unit 18 subtracts the corrected total travel distance by a predetermined distance (for example, 1000 km). If the vehicle continues to run at a speed exceeding the third reference speed for 6 minutes, the intimacy of the character is greatly reduced because there is no intention to observe the speed limit and the character's request is not heard.

  In addition, when the vehicle travels at a speed exceeding the third reference speed for 6 minutes, it is preferable that the character information output (character is not displayed) is taken so that the character is not angry. In this way, in addition to the subtraction of the corrected total travel distance greatly reducing the intimacy, the driver is lonely because the character information is not output as if the character had run away, and the driver cannot meet the character. Therefore, the driver tries to drive that does not satisfy the set conditions. Therefore, as shown in this modified example, if the driving is not preferable such as extremely dangerous driving, the driver should be appropriate. It ’s good because you ’re driving.

(Modification with character information (night drive mode) output stochastically)
As described in the embodiment, the character information is extracted from the internal data shown in FIGS. 20 to 24 based on the OBD information, the position information, the map information, and the like acquired by the control unit 18 and output. To do. In this modification, the character information is probabilistically output, and the relationship affects the probability. In this way, since the probability that predetermined character information is output depends on the relationship, the game is more interesting.

  The character information that appears with this probability is a night drive mode that is output in the night time zone. That is, as described in the embodiment, “(3) Sleeping while sleeping” (FIG. 24) outputs character information that says sleeping in a period of 5 minutes from 10 minutes to 30 minutes in the night time zone. . That is, since the character is a living creature and sleeps at night time, even if there are surrounding target objects, the presence of the target object as in the day time period is not notified. In other words, the output content of the character information varies depending on the time of day, the day of the week is the normal operation time when the character wakes up and makes various notifications, and the night time is sleeping and the main activity There is a non-normal (standby) operating time zone.

  Then, for example, when the driver travels mainly in the night time zone, character information indicating a sleeping state is output like sleeping, so it is not interesting. 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 night and sleep in the day because the human character of the character is lacking. Therefore, in this modification, the drive mode is a function that performs normal operations such as outputting character information in the daytime period based on the relationship (intimacy) even if the character wakes up by probability and is in the nighttime period. Is provided. This makes the game more fun and interesting because it works at night once a few times. In addition, the sleeping character wakes up for himself and performs normal actions during the daytime, such as notifying the presence of the target object, so it is good to be moved.

  Then, the game performance is further increased by associating the probability of operation with the relationship (intimacy). In particular, it is preferable that the probability of operation increases as the relationship becomes better because the user tries to improve the relationship.

  Specifically, when the night drive operation is triggered, when the display unit 5 is touched twice in the night time zone, the control unit 18 determines whether or not to perform the daytime operation with a predetermined probability. Two touches represent a state where the user taps lightly to wake up a sleeping person. The probability of whether or not this night drive mode is activated is increased according to the relationship / intimacy. In the above-described embodiment, the familiarity is divided into four stages from 0 to 3. 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 familiarity is 2, the probability is 3/4, and when the familiarity is 3, the probability is preferably 1/1 (100%).

In addition, it is possible to divide more finely than the rough division like four steps. For example, the level of intimacy for night drive mode is set to level = corrected total travel distance / 10000
(The level increases by 1 every 10 km),
Level * 0.25 [%]
The character activates the drive mode in response to the invitation and outputs various character information. If it does in this way, if it exceeds 4000 km, since a probability will exceed 100%, it will always start.

  In addition, a character operating in the night drive mode may be dressed in night drive wear.

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

  The OBD information includes a current fuel consumption that is an average fuel consumption from the engine ON, an instantaneous fuel consumption (every 200 ms), and a lifetime fuel consumption that is an average fuel consumption including past fuel consumption. Since the fuel consumption information is stored in the OBD information of the RAM, the control unit 18 reads and compares the instantaneous fuel consumption stored in the RAM with the current fuel consumption, and the instantaneous fuel consumption is larger (the fuel consumption is better). ) In this case, it is assumed that the vehicle is eco-driving, and a predetermined increase value (for example, 0.5) is added to the correction coefficient. Then, for example, when the normal correction coefficient is 2, the correction coefficient is increased to 2.5 during eco-driving.

  This time fuel consumption is the average of the history of instantaneous fuel consumption since the engine was turned on, so if the instantaneous fuel consumption increases, it will be reflected later in the current fuel consumption, and if the instantaneous fuel consumption decreases, then it will be reflected in this time Has been lowered. Therefore, the always instantaneous fuel consumption cannot continue to be higher in the eco state than the current fuel consumption, and the instantaneous fuel consumption alternately exceeds or falls below the current fuel consumption. Since both conditions occur, only a positive assessment was adopted.

  In particular, during a period in which the foot brake or engine brake is used without stepping on the access pedal, such as when the vehicle is stopped, the instantaneous fuel consumption increases, so that such a state should occur. Then, the current driving evaluation (whether or not eco-lucking is performed) or the like can be quickly performed.

  The driver will actively perform eco-driving in order to obtain a positive assessment. Eco-driving is preferable because it consumes less fuel and is economical, friendly to the environment, and has less fluctuation in speed, so that the ride is comfortable.

(Modification regarding character information output)
In this modification, the control unit has a function of preventing the character information from being output until the return condition is satisfied when the set condition (runaway condition) is satisfied. The conditions for running away include, for example, rough driving and not listening to what the character says. The rough driving includes, for example, driving at a speed exceeding a predetermined speed (for example, the third reference speed), and a case where a state where the acceleration exceeds a threshold value occurs multiple times over a certain period. If the character does not speak, there is a case where the driving is continued without following the warning even though the warning is given.

  The return condition includes, for example, a fixed condition such as the passage of a predetermined time and the travel of a constant travel distance, the provision of a predetermined item described later, and the like. The fixed time elapse may be, for example, the operating time of the present system or the elapsed time in the real world. If the character information is not output, the user cannot meet the character and is lonely. Therefore, the user tries to drive that does not satisfy the set conditions. Therefore, if the set conditions are unfavorable driving such as extremely dangerous driving, the user will perform appropriate driving. good. In addition, even if the character information is not output once, for example, when the standard condition is cleared, the character information is output again. By incorporating a mechanism in which character information is output under a special return condition, the user performs an action for getting an item, and the game performance is increased. For example, an item can be obtained by actually moving to a predetermined location, or by accessing a predetermined server / site and obtaining it for a fee or free of charge.

(Modification with item get function)
An installation point of an item that affects the character state 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, a viewpoint parking that is a parking lot in a good landscape location, a general roadway station, or a highway oasis. In this case, it is preferable to stop at the parking lot at the installation point as a condition for getting the item.

Since both have a parking facility, they may stop by for a break during driving, and it is preferable to use these parking facilities to give the driver rest. The reason for requiring parking at a parking lot is to exclude passing through a mere SA or the like.

  You can save the items you get and use them to affect the state of your character. The state of the character affects the output of the character information, which may increase the game characteristics.

  Items include, for example, items for improving the relationship (intimacy) (such as adding a predetermined distance to the corrected total travel distance stored in the RAM), items for which the correction coefficient for a certain period does not decrease, and items for which the correction coefficient for a certain period increases There are items for which the correction coefficient returns to the normal correction coefficient, items for returning from a state where the character disappears from the screen (appears on the screen), and items for increasing the probability that the night mode is activated.

  For example, as an item whose correction coefficient does not decrease, there is, for example, a sickness drink. When drinking a sickness drink, control is performed so that the acceleration sensor does not react for a certain period (time, mileage, etc.), that is, the correction coefficient does not decrease even if the acceleration exceeds a threshold value. That is, the control unit 18 adds without resetting L even if the acceleration exceeds the threshold value. With this, for example, a curve continues on a mountain road or the like, and driving can be performed without worrying about the acceleration even when the acceleration in the left-right direction easily exceeds the threshold value. This sickness-preventing drink should be drunk in front of the mountain road, so it should be installed, for example, at the foot station of the foot.

  An item that returns from a state where the character disappears from the screen (appears on the screen) is, for example, a present item. That is, if the run-out condition such as exceeding the third reference speed continuously three times is satisfied, the character does not appear. In such a case, for example, if a predetermined return condition is satisfied, for example, 24 hours elapses, the character appears again on the display unit. However, by giving a present item, the character's mood returns to the display unit and returns immediately.

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

  The condition for enabling the item to be provided needs to be greater than or equal to a certain threshold value (safe driving state) in addition to the selection that the item can be provided based on the probability described above. Furthermore, since SA / PA and the like are arranged on the highway, if the current vehicle traveling position does not identify the highway, the item get phrase is not uttered even if the vehicle is nearby.

  When the driver knows that a predetermined item exists in the surroundings by the item get flag phrase or the like, the driver determines whether or not he / she is a necessary item, and moves to the target object if necessary. And an item can be obtained by stopping at the target object (parking lot). The acquired item may be stored in, for example, a RAM or an EEPROM. In addition, since roadside stations are on ordinary roads, it is relatively easy to stop by many times. Therefore, the number of items in the same place is limited to 1 / day.

(Other variations)
The amount of decrease in the amount of change when the setting condition is not satisfied may be constant regardless of whether the setting condition is severe, or may be varied depending on the difficulty of the setting condition. In the embodiment and the modification described above, the change due to the familiarity is only the character voice, but the character image may be changed. Further, the vehicle speed is obtained by using the vehicle speed information included in the OBD information. However, the present invention is not limited to this, and the speed may be calculated based on the history of the position information, for example. Further, it is preferable that the number and frequency of the character outputting and talking with the voice increase as the intimacy increases. Further, the control for improving the familiarity may be performed based on the traveling speed, or based on the power ON time or the like.

  In the above-described embodiment and the modification, the radar detector of the type that is fixedly installed by attaching the bracket 3 at a predetermined position in the dashboard or other vehicle as an application device of the system of the present invention has been described as an example. However, it can also be applied to mirror-type radar detectors attached to room mirrors. Furthermore, the present invention is not limited to a 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 types of information, and the control unit 18 accesses the database 19 to read out necessary information and performs various types of processing. This is not a limitation. 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 the server, and the control unit 18 may access the server as appropriate, acquire necessary information, and execute a process. 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, the result may be acquired on the in-vehicle device side, and a predetermined display may be performed. Furthermore, the display device may use a device mounted on another in-vehicle device or vehicle.

  In the embodiment and the like, a GPS receiver that detects current position information is built in, but in the present invention, a configuration including a GPS receiver is not essential, and current position information is acquired from a vehicle or other in-vehicle device, and the acquired information Based on the above, it may be determined whether or not there is an approach relationship with the alarm target.
