Description

The present invention relates to a system and a program that output character information to a driver.

For example, Patent Document 1 discloses a system that changes character information such as facial expressions and gestures of a character displayed on a display screen according to the situation of a vehicle. The invention disclosed in Patent Document 1 expresses a virtual emotion assuming that the vehicle has a personality by the facial expression of the character. For example, if the driver drives violently and the vehicle has emotions, the vehicle may feel uncomfortable, so the character may be angry or sad as a virtual emotion of the car. Output. On the contrary, if the driver drives carefully and gently, it is considered that the virtual emotion of the vehicle will be comfortable, so the facial expression that the character is pleased or energetic is output.

The above system encourages the driver to drive safely by taking advantage of emotions such as the driver trying not to make the character uncomfortable or wanting the character to be pleased.

Japanese Unexamined Patent Publication No. 2003-72488

In order to support safe driving with the above system, it is necessary to make the driver feel strongly that he / she does not make the character uncomfortable and that he / she wants to be pleased. Therefore, it is necessary for the driver to strongly empathize with the character, but in the system disclosed in Patent Document 1, for example, the facial expression of the character when the driver's driving is rough or polite is the driving state. It is determined uniformly according to. Since the facial expressions and gestures of the character displayed on the display screen are monotonous and hardly change, the driver tends to get tired of communicating with the character. Therefore, the state in which the driver strongly embraces the character does not continue, and the driver may not feel anything even if the facial expression or gesture of the character eventually changes. As a result, the above-mentioned system has a problem that it cannot promote safe driving.

In addition, regardless of whether or not emotions are transferred, for example, if the output of character information is rich in variety, the game quality is enhanced. 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 property is low because the change of the character is small.

An object of the present invention is to provide a system and a program capable of continuously encouraging a driver to drive safely by maintaining a strong emotional empathy of the driver with respect to the character.

(1) The system according to the present invention is a system that changes the relationship with a character and controls the output of character information according to the relationship, and has a function of improving the relationship and traveling of a vehicle. It has a function of controlling the amount of change when the relationship is satisfactorily changed based on the information regarding the above.

This system is realized, for example, by an in-vehicle device fixedly installed in a vehicle, a portable device that is brought into the vehicle during driving, and the like. By outputting character information during driving, for example, a creature such as a person or an animal is characterized and made to be recognized by the user. 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 character information may be output by displaying the character image on a display unit (display or the like) or by outputting the character voice from the voice output unit (speaker or the like).

This system outputs character information according to the relationship with the user. The relationship is the degree of connection between the user and the character, the degree of involvement, etc., and may be regarded as, for example, intimacy, reliability, and the like. A good relationship means a good relationship between the user and the character, and may be regarded as having a high or strong relationship. By outputting the character information according to the relationship with the character, the user can easily embrace the character and make the user feel as if the character is a real object.

The character information has a good relationship with the user, for example, by making the content like a kind of reward that the better the relationship is, the more variation is made, and the user is familiar with the character information and the user is happy. Perform the action to become. Therefore, for example, if the mechanism is such that the relationship becomes better as the driver drives safely, the user can maintain the relationship with the character in a good condition and further increase the degree of goodness. , You will actively try to drive safely.

Since the character information depends on the relationship, the output mode differs depending on the degree and degree of goodness. Different output modes, for example, different output means / media such as adding sound to an image only at the beginning, but animated display from a still image at the beginning, or different costumes for the same still image. Or, the content of the animation may be different, and the output content may be different with the same output means / medium.

The function of improving the relationship is, for example, to improve the relationship based on the acquired predetermined information, that is, to increase / strengthen the degree of goodness. In general, the longer you stay together, the better the relationship. Therefore, the predetermined information may be information related to the running of the vehicle, such as the mileage, and may be controlled so that the longer the mileage, the better the relationship. The longer the mileage, the longer the period of stay with the user, and the longer the mileage is, the better the relationship. Further, in view of the fact that the longer the relationship is, the better the relationship becomes, for example, it may be based on the operating time. The operating 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 operating time is such that the user and the character are in the vehicle together. It can be regarded as the boarding time. In this way, the function of improving the relationship should be controlled so that the longer the time spent together, the better the relationship. The function for improving the relationship may be controlled to improve the relationship based on information other than the illustrated mileage and operating time.

When comparing the mileage and the operating time as information for performing control for improving the relationship, the mileage is preferable. For example, the mileage is 0 when the vehicle is parked and stopped with the engine running, and the mileage is extended when the vehicle is driven for the same time as the parked and stopped time. If you control to improve the relationship based on the operating time, the relationship will be improved to the same extent in both cases, but if you give the character a personality, you will get on the parked vehicle together. It is better to base it on the mileage because the character feels more happy when actually driving than when it is. Further, when the vehicle is parked and stopped, the driver who is the user may be sleeping with the engine running. Then, the character becomes lonely, and it is hard to say that the sensitivity with the user is improved. On the other hand, when the vehicle is running, the driver, who is the user, is guaranteed to be awake and with the character. Considering this point, it is preferable to use the mileage. In addition, when traveling in the city and in the suburbs for the same time, the mileage is longer when traveling in the suburbs where there is less waiting for traffic lights and the speed is faster. Furthermore, if you use the highway, the mileage will be longer. If you are driving in the city, you are more likely to drive for normal activities such as commuting or shopping, and if you are using the suburbs or highways, you are more likely to drive for fun events such as travel. I can say. Therefore, it is preferable to use the mileage so that the difference makes a difference in the control for improving the relationship. Furthermore, in terms of operating time, for example, assuming that this system is mounted on a portable device and the vehicle can be removed and carried around, power is supplied not from the vehicle battery or the like but from a commercial power source or the like. The system can be operated by turning on the power regardless of driving. Then, even if the user is away from the portable device with the power turned on, the operation time is added and the control is performed, which is not so preferable. Therefore, it can be said that it is fair and preferable to perform control to improve the relationship based on the mileage.

Since it has a function of controlling the amount of change when the relationship is satisfactorily changed based on the information on the running of the vehicle, for example, the function of improving the relationship serves as an opportunity to acquire the function of improving the relationship. Even if the predetermined information is the same, if the amount of change based on the information is different, the degree and degree of good relationship will be different. Therefore, even if the input information (predetermined information acquired above) is the same, the output result may be different, which makes the system interesting and rich in gameplay. Further, since the control of the amount of change is performed based on the information on the running of the vehicle, the amount of change is increased or decreased depending on the actual driving of the driver. Therefore, the larger the amount of change, the more efficiently the relationship becomes better. Therefore, when the driver who is the user tries to enhance the relationship, he / she strives to perform the operation 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 (predetermined information acquired above) that is the basis for improving the relationship. For the addition, for example, a parameter (coefficient) is multiplied, or a parameter (predetermined value) is added or subtracted each time the input information becomes a certain amount. Further, the amount of change may be changed according to a predetermined function, or the amount of change may be changed according to a predetermined rule.

(2) It is preferable that the character information is a reward that the user is pleased with as the relationship is better. In this way, as described in (1), the user has a strong desire to maintain a good relationship so that he / she can receive a reward, or to perform an operation / driving so that the relationship becomes better. Become.

(3) It is preferable to provide a notification means for notifying information on the current amount of change in the function of controlling the amount of change. The information regarding the amount of change may be the amount of change itself, or may be information corresponding to the amount of change or specifying the amount of change. In the embodiment, this amount of change corresponds to the correction factor. By knowing the current amount of change, the user can immediately understand how the amount of change is changed / reflected depending on the current driving method and driving condition. You can know if it will grow. Therefore, the user can perform a driving operation in which the amount of change is larger. In addition, by notifying the user of the current amount of change, it is possible to motivate the user to maintain the state as it is or to improve the amount of change.

(4) The notification means may be provided with a display area for displaying information regarding the amount of change. (5) In that case, the display area may be an indicator. Such an indicator method is preferable because the current state of the amount of change can be seen at a glance from the 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) Further, the notification means may make the appearance of the character correspond to the information regarding the amount of change. The change in the character's appearance should be a kind of reward that makes the user more familiar and happy as the amount of change increases. Changes in the appearance include, for example, changing the facial expression, changing the animation motion, 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"-> "muffled" in order from the side with the largest amount of change. For example, the larger the amount of change, the larger and more flashy the animation movement, or the animation that dances to express happiness and enjoyment. In addition, the smaller the amount of change, the smaller the movement, the immobility, or the depression. By using the change in the character's appearance, the user can easily accept the current magnitude of the change, unlike the notification using an inorganic indicator or numerical value. And, for example, when the character has a sad face in the control state where the amount of change is small, it is one of the factors that the user tries to drive so that the control state where the amount of change is large is to make the character laugh. Become. The change in the character's appearance may be performed independently, but it may be linked with the notification by the indicator or other display area. Since it is not possible to gaze at the display unit for a long time during driving, it is preferable that the character's appearance changes as auxiliary information for notification in the display area such as an indicator, so that it is easier to understand.

(7) The function of improving the relationship is controlled so that the higher the degree of being with the machine, the better, and the function of controlling the amount of change is actually based on the information on the running of the vehicle. It is advisable to control the amount of change to be different from the reference amount of change that changes satisfactorily depending on the degree of presence with the machine.

This machine is a device or the like on which this system is mounted. The degree of being with this machine is the degree of the user being with this machine, and the higher the degree of being with this machine, the stronger the connection between the user and the character, for example, the greater the degree of trust from the character, and the more the relationship is. Since it can be estimated that it will become stronger, the control is performed so that the higher the degree of contact with this machine, the better the relationship. The degree of use of this machine is determined based on, for example, mileage, operating time, driving time, various acquired driving conditions, and the like. For example, in the case of mileage, control is performed so that the longer the total mileage, the better the relationship, and in the case of operating time, the longer the total time during which the power of the machine is on, the better the relationship. Control so that

Assuming that the standard change amount, which changes in good degree and degree depending on the degree of actual presence with the machine, is used as the reference change amount, the function for controlling the change amount is changed to a change amount different from the reference change amount, so that the vehicle is actually used. The change in the degree / degree of goodness of the relationship obtained by running the machine may differ from the degree / degree of goodness of the relationship obtained based on the degree of actual presence with the machine, and the game quality is improved. Come out.

(8) It is preferable that the function of controlling the change amount is to perform a plus assessment process for making the change amount larger than the reference change amount and a minus assessment process for making the change amount smaller than the reference change amount. .. In this way, the relationship becomes better than it can be obtained in normal driving, and the good relationship does not grow well, so that the game becomes more interesting. By driving so as to be a positive assessment process, the degree of good relationship is increased in a short period of time, and character information corresponding to the degree is output. Therefore, even a person who does 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, the relationship can be obtained in a short period of time. It is possible to recover the degree and degree of goodness of.

(9) The amount of change smaller than the reference process may include a negative value. In such a negative state, the more the vehicle travels, the worse the relationship becomes than the current state. By providing such a negative value, the user will not perform a driving operation that causes at least a negative value. Therefore, for example, when a large degree of dangerous driving is performed, or when the driving is not improved, the amount of change is not observed. It is advisable to set the value to a negative value by repeating the situation / situation where becomes smaller.

(10) The function of controlling the amount of change may be such that when the acquired information on the running of the vehicle does not satisfy the setting conditions, the amount of change is reduced and returned to the original size after a lapse of a predetermined period. The predetermined period is a set predetermined time, a period during which the vehicle finishes traveling a set predetermined distance, and the like. As a method of returning to the original size, for example, the reduced amount of change may be gradually returned by a time constant or the like, or the reduced amount of change may be maintained for a predetermined period and then returned at once. When returning gradually, it may be continuous or stepwise.

In this way, once the setting condition is not satisfied and the amount of change becomes small, even if the setting condition is satisfied immediately after that, the state is maintained in a state where the amount of change is small for a predetermined period instead of returning immediately. For example, unfavorable driving conditions such as dangerous driving and traffic violations may lead to accidents if they occur even momentarily or for a short time, so it is better not to be in such a state during the driving period. Therefore, the user tries to drive so as not to satisfy the set condition even for a momentary time, and it is preferable because the set condition can contribute to safe driving and the like. Further, if the setting condition is not satisfied even once, even if the driving that satisfies the setting condition is performed after that, the original state is not restored until a certain period of time elapses, which 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 on the running of the vehicle satisfies the set condition as the setting condition becomes stricter. It is good to do.

If the setting conditions are strict, there is a demerit that a state with a small amount of change occurs for a certain period of time without satisfying the setting conditions due to a slight difference in driving operation, but if the setting conditions are satisfied, the state with a large amount of change continues. However, the degree and degree of goodness of the relationship increases in a short period of time, and various character information according to the relationship can be obtained. Therefore, it becomes like a high risk and a high return, and the game quality is increased. In addition to simply increasing the gameplay, driving that meets stricter setting conditions usually results in a safer and more environmentally friendly driving state, such as safer driving or eco-driving. Since it is often the case, it is also preferable for the traffic environment.

The amount of reduction in the amount of change when the setting condition is not satisfied may be constant regardless of whether the setting condition is strict or not, or the amount of reduction may be different depending on the difficulty level of the setting condition. Further, the control of the amount of change when the setting conditions are satisfied when there are a plurality of sets of the information related to the running of the vehicle and the setting conditions is, for example, the setting conditions of each set when the setting conditions of all the sets are satisfied. It is advisable to set the total amount of increase in the amount of change set according to the difficulty level of the above, and to control to reduce the amount of change if even one setting condition is not satisfied. Further, as another method of controlling the amount of change, for example, 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 for each group, and whether or not the set condition of the group is satisfied is determined. It may be possible to make a judgment and determine the amount of change comprehensively, and various methods can be adopted.

(12) On the premise of the invention of (11) above, as an interface for inputting the setting conditions, an input screen for designating relative multiple levels is displayed, and for each level of the plurality of stages of the input screen. Therefore, it is preferable to associate the setting condition with the amount of change when the setting condition is satisfied. The user only has to specify a plurality of levels from "strict (difficult)" to "loose (easy)", and can intuitively specify the setting conditions. In addition, under the current setting conditions, if the conditions are often not satisfied, the setting conditions are loosened by one or more steps, and conversely, if the setting conditions are always satisfied, the setting conditions are set to be stricter by one or more steps. You can make adjustments to increase the amount of change, and you can easily set appropriate conditions.

(13) On the premise of 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, it is possible to immediately set the standard amount of change. For example, if it is determined whether or not the setting conditions performed during traveling are satisfied every unit time (for example, 1 second), information on the traveling of the vehicle to be determined is acquired at least every unit time. Then, the judgment process will be performed. Therefore, normally, the determination during traveling is stored in a volatile storage unit such as a RAM, and the determination process is appropriately performed. Therefore, the information on the running of the vehicle immediately before the stop, which is stored in the volatile storage unit when the engine is stopped (ignition off), is not retained. Therefore, immediately after the engine is started, the information on the running of the vehicle is not obtained or the setting condition is set. It may not meet. Therefore, even if the setting condition is not satisfied, the standard change amount can be immediately restored by setting the predetermined period to 0.

For example, if the information related to the running of the vehicle is stored in the non-volatile storage unit, the determination process is performed based on the information related to the running of the vehicle stored in the non-volatile storage unit immediately after the start, so that the function of setting the predetermined period to 0 is available. It is not necessary to provide it, but as described above, if the information on the running of the vehicle is updated in a short cycle unit time, the upper limit of the number of rewritable times of the non-volatile storage unit will be reached immediately, which is practical. Instead, it is preferable because a simple process such as setting the predetermined period to 0 can solve the problem immediately after the engine is started.

If the number of rewritable times of the non-volatile storage unit increases significantly, or if a backup power supply or the like is installed and the vehicle engine is stopped, the information regarding the running of the vehicle stored in the volatile storage unit can be retained. , They may be used.

(14) On the premise of the inventions (10) to (13) above, it is preferable to have a plurality of sets of acquired information on the running of the vehicle and setting conditions, and the setting conditions may be set for each set. The multiple sets may differ in both information and setting conditions regarding the running of the vehicle, or may have one in common. For example, when both sudden start and sudden stop are judged, both can be detected by the acceleration applied in the traveling direction of the vehicle, so the information on the running of the vehicle is one acceleration and the output of the sensor, but the positive and negative outputs are opposite. Therefore, the setting conditions are different, and there are two sets. The same applies when detecting a sudden left or right steering wheel operation.

For example, depending on various usage conditions such as the driving habits of the user, the characteristics of the vehicle, the condition of the road on which the vehicle is traveling, and the installation position of the machine equipped with this system, it may be possible to easily meet even strict installation conditions. , May not be possible. Therefore, by setting the setting conditions individually, it is possible to increase the amount of change while satisfying the setting conditions of all the sets.

(15) The character information may be provided with something that is output stochastically, and the relationship may affect this probability. In this way, the probability that the predetermined character information is output depends on the relationship, which makes the game more interesting.

(16) On the premise of the invention of (15) above, 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 / degree of good relationship, or may be continuously increased in predetermined range intervals.

(17) On the premise of the inventions (15) and (16) above, the character information differs depending on the time zone, and the time zone includes a normal operating time zone and an abnormal (standby) operating time zone. Therefore, it is preferable to output the character information in the normal operating time zone based on the probability in the abnormal operating time zone. The time zone may be divided into two, for example, a day time zone and a night time zone, or may be further divided into three or more. For example, if the character is divided into a daytime time zone and a nighttime time zone, the character goes to bed at night, so the daytime time zone becomes a normal operation time zone and character information according to the relationship is output, but at night. The time zone is an unusual operating time zone, and the character information indicating the sleeping state can be output regardless of the relationship. In the case of this aspect, the character information indicating the sleeping state is output, which is not interesting for the user who mainly drives at night. In such a case, the operation time zone may be set to be reversed between day and night, but normal operation such as output of character information based on the relationship even if the character wakes up due to a probability and is in an unusual operation time zone. If you have a function to do, it will work even at night once every few times, so it will be more game-friendly and interesting. Then, by associating the probability of operation with the relationship, the game quality is further increased. In particular, it is preferable to make the probability higher as the relationship becomes better, because the user tries to make the relationship better.

(18) When the set condition is satisfied, the character information may not be output until the return condition is satisfied. The return conditions include, for example, standard conditions such as the passage of a certain time or running a certain mileage, and the addition of a predetermined item. The elapsed time may be, for example, the operating time of the system or the elapsed time in the real world. When the character information is not output, the user cannot meet the character and becomes lonely. Even if the character information is not output once, for example, if the standard condition is cleared, the character information is output again, but if the standard condition is not cleared, for example, an item is given. By incorporating a mechanism in which character information is output according to special return conditions, the user will perform an act to get an item, and the game quality will increase. For example, you can get an item by actually moving to a predetermined place, or you can access a predetermined server site and get it for a fee or free of charge.

(19) It is preferable to provide a function for controlling the deterioration of the relationship. As described above, the basic configuration of the present invention is to control the relationship to be good and to control the amount of change to improve the relationship. Then, there is a control that worsens the relationship at once, for example, by directly deducting points for the degree and degree of goodness of the relationship. For example, if this deteriorating control is performed when the set deduction condition (predetermined speed exceeding 3 times in a row) is satisfied, the relationship accumulated up to now will be destroyed at once, so the user is concerned. We can expect to make efforts so that the situation does not occur. Therefore, it is preferable that the deduction condition matches the operation or the like, which is more unfavorable than the condition for controlling to reduce the amount of change. Further, as in the invention described in (9) above, making the amount of change negative can 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 controlling the deterioration of this relationship.

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

(22) The function of controlling the amount of change may be performed based on the operating state. Driving conditions include, for example, dangerous driving such as sudden acceleration (starting / running) / sudden deceleration (stopping / running), sudden steering (sudden turning), and unfavorable driving conditions such as non-eco-friendly driving. is there. When a particularly unfavorable operating state is detected, it is advisable to perform control so as to reduce the amount of change.

(23) On the premise of the invention of (22) above, the operating state is sudden acceleration (starting, running) obtained from the acceleration in the traveling direction of the vehicle, and sudden deceleration (stopping) obtained from the acceleration in the traveling direction of the vehicle. , While traveling), it may be at least one of the sudden changes in the traveling direction obtained from the acceleration in the direction intersecting the traveling direction of the vehicle.

(24) On the premise of the invention of (23) above, the sudden change in the traveling direction may be distinguished between a right turn and a left turn. For example, if the installation position of the means for detecting acceleration (for example, the acceleration sensor) (the installation position of the machine when it is built in the 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 differs depending on the turning direction. Therefore, by changing the setting conditions according to the installation position, it is possible to open a defect due to the difference in the installation position.

(25) The function of controlling the amount of change may reduce the amount of change under certain conditions in the event of a traffic violation. In this way, the user can be expected to drive while trying not to violate the traffic.

(26) On the premise of the invention of (25) above, the above-mentioned certain condition may be a violation of the same kind in the same place. The same type of violation at the same location includes, for example, a pause violation at the same point or an overspeed at the same point. Repeating the same type of violation multiple times at the same place lacks attention and can be said to be a worse violation than the first time, so the amount of change should be reduced when repeated multiple times.

(27) On the premise of the inventions (25) and (26) above, it is preferable that the certain condition does not reduce the amount of change in the first violation. The first breach gives grace without reducing the amount of change. As a result, the motivation of the user is not lowered because the amount of change does not decrease, and it is possible to be careful not to violate the next time, and as a result, safe driving can be promoted. It is good to give a warning at the time of the first violation.

(28) On the premise of the inventions (25) to (27) above, it is preferable to reduce the amount of change by violating N times or more as a certain condition. 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 you notice the overspeed, and if you suddenly reduce the speed to below the speed limit, you will suddenly decelerate, which is rather dangerous. On the other hand, if the speed is continuously exceeded for a certain period of time, it can be estimated that there is no intention to decelerate and keep the speed limit, and the driving is dangerous. Therefore, it is advisable to reduce the amount of change only after N or more violations. At this time, it is advisable to give a warning up to [N-1] times.

(29) It is advisable to change the degree of reduction of the amount of change according to the degree of violation of the above (25) to (28). For example, overspeed is more dangerous as the overspeed from the speed limit increases, even if it is the same overspeed violation. Therefore, it is better not to reduce the amount of change as the same excess speed violation, but to increase the amount of change as the degree of violation increases. Here, changing the degree of reduction of the amount of change means, for example, changing the absolute amount at which the amount of change is once reduced when a violation is made according to the degree of violation. For example, the greater the degree of violation, the greater the absolute amount when lowering. Further, as another example of changing the degree of reduction of the amount of change, even if the amount of reduction of the amount of change at the time of violation is the same, the period required for returning to the normal amount of change may be lengthened. For example, the greater the degree of violation, the longer the time required for recovery. Further, as another example, the increase in the amount of change may be delayed until the amount of change returns to the normal amount. These controls may be realized in combination.

(30) On the premise of (29) above, the degree of violation is an excess speed that exceeds the first reference speed, and if the second reference speed that exceeds the first reference speed is exceeded, the excess speed It is preferable to reduce the amount of change more than the degree of reducing the amount of change according to the above. The first reference speed may be, for example, a speed limit, or may be a speed obtained by adding a predetermined margin (for example, 20 km / h) to the speed limit. Then, the second reference speed may be, for example, a speed at which a one-shot suspension is achieved (over 30 km / h). It can be said that the state of overspeed, which is a one-shot suspension, is a very dangerous driving state that leads to a big accident. In such a driving state, the feeling of the character assuming that the character also has a personality is very scary compared to, for example, a slight overspeed, and the intimacy and reliability with respect to the user who is the driver also decreases. There is. Therefore, when the second reference speed is exceeded, the amount of change is greatly reduced, that is, a very small value is set. With such a setting, on the contrary, the user will drive carefully so as not to cause such a situation, and as a result, safe driving without excessive speed exceeding the above-mentioned second reference speed. Can be encouraged.

(31) On the premise of (30) above, the first reference speed may be a speed obtained by adding the set speed to the speed limit. The set speed may be, for example, 20 km / h. If you are driving while the surrounding vehicles are running, you may unknowingly exceed the speed limit. In this case, if you dare to drive only your own vehicle while observing 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 the speed is slightly exceeded. You can drive according to the flow of surrounding vehicles.

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

Generally, the speed limit of an expressway is 80 km / h or 100 km / h. On the other hand, there are some such as the Metropolitan Expressway where the speed limit is set to 60 km, which is slower than the speed limit of general expressways. Surrounding vehicles may travel at speeds similar to or close to the speed limit of ordinary highways (for example, 90 to 100 km / h). In such a case, it is important to observe the traffic rules, but if only the own vehicle is traveling at the speed limit of 60 km / h, the speed difference from other vehicles becomes 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 driving according to the surroundings.

(33) On the premise of the inventions described in (23) to (32) above, a warning is given that the amount of change will decrease if the same type of violation is made next, and the above change will occur if the same type of violation is made next. It is good to reduce the amount. Rather than suddenly lowering (worse) the amount of change, it is possible to urge the user not to violate by warning. If the same violation is made despite the warning, it means that the advice from the character is ignored, and the control to reduce the amount of change is performed. This corresponds to, for example, a control in which the correction coefficient is not lowered in the first pause violation in the modified example.

(34) On the premise of the inventions described in (23) to (33) above, it is preferable to reduce the amount of change and then restore the amount of change to the original amount by a predetermined function (algorithm, rule). (35) The predetermined function may delay recovery as the degree of violation increases. The degree of violation includes, for example, the degree of the violation in one violation such as the magnitude of the overspeed, and the degree of maliciousness such as the repetition of the same violation in the same place. The higher the degree of violation, the worse the intimacy and reliability of the character with respect to the user. Therefore, by delaying the recovery, the state in which the change to the extent that the relationship becomes good continues for a long time, and the growth to the extent that the relationship becomes good is reduced. Further, although it is not a traffic violation, a state in which the amount of change is reduced based on a driving state such as an acceleration exceeding a threshold value is performed as in the inventions described in (22) to (24). If this is repeated, it is advisable to delay recovery. For example, if the character is repeatedly driven uncomfortable, the feelings toward the user when the character is given personality and emotions will be worsened, and it will take a long time to recover from the mood, so the original amount of change will be restored. It is good to take a long time to do it.

(36) The function of controlling the amount of change may be performed based on the eco-driving situation. Eco-driving is calculated based on, for example, fuel efficiency. For example, control is performed to increase the amount of change in the case of eco-driving and to decrease the amount of change in the case of non-eco-driving. In addition, if it is eco-driving, a positive assessment that increases the amount of change is performed, but if it is not eco-driving, the amount of change is not changed (no negative assessment is performed), and conversely, if it is eco-driving, the amount of change is not changed (plus assessment). If it is not eco-driving, a negative assessment to reduce the amount of change may be performed. Eco-driving is economical because it consumes less fuel, is environmentally friendly, and has less speed fluctuations, which makes driving comfortable. It can be said that the feelings of the driver are delighted and the intimacy and reliability of the user are increased. Therefore, the amount of change is controlled based on the eco-driving situation.

(37) It is preferable to set an installation point of an item that affects the state of the character on the map, and when the vehicle goes to the place of the installation point, the item is obtained with a certain probability. It is good that the obtained item affects the state of the character by using it, for example, and it is good that the item can be saved. The state of the character affects the output of the character information, which is good because the game quality is increased. A certain probability may be 100% (always received), or less than 100% (does not appear), so that the game quality will be further improved. This probability may be fixed depending on the whole or the type and place of each item, or may vary depending on the degree and degree of good relationship at that time.

As an item to get,
・ Improve relationships (improve relationships, bonus points, etc.)
・ The amount of change does not decrease / increase / return to standard ・ Return from the state where it disappeared from the screen (appears on the screen)
-The probability of the invention described in (15) and the like is increased. The "get" 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 obtained item may be used. Then, the processing related to the stored item type may be executed at a predetermined timing.

(37) An item installation point that affects the character's condition is set on the map, and when the vehicle goes to the location of the installation point, the item has a function of getting the item with a set probability. The get should 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 realizing the function in the system according to any one of (1) to (37) in a computer.

According to the present invention, it is possible to provide a system capable of continuously encouraging the driver to drive safely by maintaining a strong emotional empathy of the driver for the character. Moreover, the output character information corresponds to the relationship with the character, and in order to control the amount of change when the relationship is satisfactorily changed based on the information on the running of the vehicle, for example, the mileage, etc. Even if the degree of being with this machine is the same, different character information is output if the running condition of the vehicle is different. Therefore, since the character information output by the user changes depending on how he / she drives his / her own vehicle, the gameplay is also improved. Further, it is possible to encourage the user to drive so that the amount of change is large.

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

"Basic configuration of electronic devices"
1 and 2 show the configuration of a radar detector, which is an embodiment suitable as an electronic device constituting the system of the present invention. The radar detector 1 is provided with a thin rectangular case body 2, and is attached and fixed on the dashboard of the vehicle or the like by using a bracket 3 attached to the lower side of the back surface of the case body 2.

A display unit 5 is provided on the front surface of the case body 2 (the surface facing the rear of the vehicle (driver side)). The display unit 5 is composed of a 3.2-inch color dot matrix TFT liquid crystal display. A touch panel 6 for detecting which part of the display unit 5 is touched is provided on the display unit 5. Further, a volume adjustment button 7 is arranged on the right side of the front surface of the case body 2, and various work buttons 8 are arranged on the left side of the case body 2.

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

The database 19 can be realized by a non-volatile memory (for example, EEPROM) inside 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 the whole of the database 19. In addition, map data and information on a certain alarm target are registered in the database 19 at the time of shipment, and data and the like on the alarm target added after that are updated as described above.

The GPS receiver 13 is arranged inside the upper center of the back side of the case main body 2, and the microwave receiver 14 and the wireless 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 speed measuring device. The radio receiver 15 receives radio waves in the UHF band 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 arranged 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 a vehicle via the cigar plug cord so that power can be supplied.

The acceleration sensor 22 is arranged 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 in the traveling direction on the X-axis, the acceleration applied in the lateral direction on the Y-axis, and the acceleration applied in the vertical direction on the Z-axis. As a result, the X-axis detects sudden acceleration / deceleration, the Y-axis detects sudden steering, and the Z-axis detects predetermined behavior of the vehicle such as riding on a step or falling into a depression.

The case body 2 has an OBD adapter 21 that is detachably attached to the OBD-II (II is the Roman numeral "2", hereinafter "OBD-II" is referred to as "OBD2") connector mounted on the vehicle. Is connected. The OBD2 connector is also called a failure diagnosis connector, is connected to the ECU of the vehicle, and periodically outputs various vehicle information. Therefore, by connecting the OBD adapter 21 and the OBD2 connector on the vehicle body side, the control unit 18 periodically acquires various vehicle information.

The vehicle information includes vehicle speed, injection injection time, intake air amount, residual fuel information, and the like. Residual 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 residual fuel on a regular basis and recording the timing when the change occurs between the previous residual fuel and the current residual fuel, it is consumed from the previous change to the current change. It can be said that the amount of fuel used is 0.5 liters. In addition, some information on fuel consumption (information on lifetime fuel consumption, current fuel consumption, instantaneous fuel consumption, etc.) is output on a regular basis.

Further, the OBD adapter 21 is detachably linked to the connection terminal 23 provided on the case body 2. When the vehicle information from the OBD2 connector is not required, the OBD adapter 21 can be removed to prevent the wiring from being cluttered on the dashboard or the like, and to make the surroundings of the radar detector clear.

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

The function of the radar detector 1 of the present embodiment is realized by being stored in the EEPROM of the control unit 18 as firmware executed by the CPU of the control unit 18 and being executed by the CPU of the control unit 18. The firmware stored in the EEPROM can be updated by the new firmware stored in the memory card.

The main information output from the output device of the radar detector 1 as a driving support system is warning information for urging the driver to be safe. The alarm information is output in the following cases, for example. The control unit 18 obtains the distance between the target 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 obtained. When the distance is less than the specified distance, alarm information is output from the output device. Further, 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 measuring device. The radar detector 1 outputs warning information to make the driver recognize a dangerous place where a traffic accident is likely to occur. As a result, the radar detector 1 can encourage the driver to drive safely. The above-mentioned warning information is an example, and actually, various other warning information is output to the driver.

(Display mode)
FIG. 3 shows the display mode of the radar detector 1. The control unit 18 displays the screen on the display unit 5 in different modes 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 constant modes. 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 tilted state of the vehicle, a screen showing the acceleration applied to the vehicle, and the like. Is a mode for displaying on the display unit 5. In OBD display mode, instantaneous fuel consumption, current fuel consumption, fuel flow rate, vehicle speed cooling water temperature, trip meter, national road average fuel consumption, general road average fuel consumption, highway average fuel consumption, engine speed, engine load factor, throttle opening, etc. This mode displays the screen shown (see FIG. 6) on the display unit 5. The MAP display mode is a mode in which a map of the vicinity of the vehicle is displayed on the display unit 5 (see FIGS. 7 to 9). This display mode switching is performed based on the pressing of the work button 8. That is, each time the upper work button 8 is pressed, the control unit 18 switches the display mode in a predetermined order.

An alarm display mode, which is a display mode when alarm information is output, will be described. In the radar standby display mode and the OBD display mode, a telop indicating alarm information is superimposed on the screen corresponding to each constant display mode, and a warning sound is output from the speaker 16. On the other hand, in the MAP display mode, the output mode of the alarm information can be switched to an animation mode, a live-action mode (hereinafter, these are collectively referred to as a non-character mode), and a character mode. The control unit 18 receives the press of the lower work button 8 and alternately switches between the character mode and the non-character mode. As shown in FIG. 7, in the animation mode, the control unit 18 superimposes and displays the animation 101 of the target object and the speed measuring device 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 displays the real-life (REALPHOT) 102 of the target object and the speed measuring device as warning information on the map 100, and outputs a warning sound from the speaker 16. As shown in FIG. 9, in the MAP display mode-character mode, the control unit 18 superimposes and displays the character 104 on the map 100. Further, the control unit 18 outputs the sound of the character 104 from the speaker 16. The 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 its operation in the character mode (inside the thick frame in FIG. 3) in the MAP display mode. When the radar detector 1 operates in the MAP display mode-character mode, the character 104 may be displayed on the display unit 5 even in a state where it is not necessary to notify the driver of the alarm information. The character 104 behaves as if it were a real person and communicates with the driver by talking to the driver. Further, the character 104 changes the behavior and the sound according to the intimacy, which 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. Further, the character 104 outputs not only notification of a dangerous place where a traffic accident is likely to occur, but also warning information for dangerous driving, violent driving, lack of concentration, and drowsy driving as warning information. A driver who wants to deepen the degree of emotional transfer to the character 104 will obediently respond to the alert from the character and actively try to drive safely. Radar detector 1 suppresses the driver from getting tired of communicating with the character by developing and maintaining the degree of emotional empathy of the driver for the character to a high level, and continues safe driving for the driver. Can be encouraged.

The above-mentioned display modes (constant 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 etc.)
The details of the information stored in the database 19 will be described with reference to FIG. Output information, map information, and setting information are stored in the database 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, start information, and setting screen information. The event information notifies the driver of various events when it is determined that the state of the vehicle or the driving state is a predetermined state (hereinafter referred to as when an event occurs) based on the information input from the input device. This is the information output from the output device to perform the above. The standby information is information output from the output device in a state in which no event has occurred (hereinafter referred to as a standby state). The logo information, the still screen information, and the activation information are information that is first output from the output device when the radar detector 1 is activated in the state of being set to the MAP display mode-character mode. The setting screen information is information on the screen displayed on the display unit 5 when the driver performs a setting input operation on the radar detector.

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

The map information is information for displaying the map 100 on the display unit 5, and includes information on the target target, 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 associated with information indicating the type of the target object, latitude / 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. Target targets are fixed speed measuring devices (including speed measuring devices that emit radar waves (microwaves) like radar and speed measuring devices that do not emit radar waves such as loop coils), doze driving accident points, radar, etc. Speed limit switching point, control area, inspection area, ban monitoring area, N system, traffic monitoring system, intersection monitoring point, signal ignoring deterrence system, police station, accident-prone area, on-board aiming area, sudden / continuous curve ( Expressway), branch / confluence point (expressway), ETC lane advance guidance (expressway), service area (expressway), parking area (expressway), highway oasis (expressway), smart interchange (expressway), There are gas stations (expressways), tunnels (expressways), highway radio reception areas (expressways), prefectural border announcements, roadside stations, viewpoint parking, etc. in PA / SA.

Traffic rule information is information about traffic violations. Information on traffic violations includes information on pauses and information on speed limits. The information regarding the suspension includes location information that identifies the place where the suspension should be performed. The place to be paused is at least the location information that identifies the place where the road sign that specifies the pause is installed. The information regarding the speed limit is information that identifies the speed limit and the road on which the speed limit is set. Information for specifying a road includes position information for specifying the position of a road and a road type (expressway / 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.

The details of the information stored in the RAM in the control unit 18 will be described with reference to FIG. 11A. The RAM stores, for example, the current date and time, vehicle position coordinates, correction information, total corrected mileage, intimacy, peripheral information, driving state, OBD information, and event flags.

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 by 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. The history since the engine was turned on is stored.

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

The corrected total mileage is information obtained by correcting the actual mileage of the vehicle based on a predetermined condition. In the present embodiment, the corrected total mileage is calculated based on the actual mileage calculated based on the history of changes in the vehicle position coordinates and the above correction coefficient. Further, this corrected total mileage can be said to be a virtual total mileage based on the mileage in the virtual space with respect to the mileage in the real space.

Intimacy is an index showing the degree of relationship with the character. The character information is output and changes according to the degree of intimacy. The higher the intimacy, the more character information such as a reward that the driver who is the user wants is output. Focusing on the mileage as the degree to which the user has been with the radar detector and thus the character, the longer the mileage, the higher the degree of being together, and the better the relationship between the driver and the character, that is, the higher the intimacy. Is the basis. This is because as the total mileage increases, the driver drives for a long time and a long distance with the character, and the relationship becomes better. In the present invention, the intimacy corresponding to the total mileage is not uniquely specified, for example, the intimacy is increased by one step when the actual total mileage exceeds the set threshold value. The amount of change when the relationship based on the increase in the mileage of the vehicle is changed satisfactorily is changed. That is, the intimacy is obtained based on the corrected total mileage obtained based on the above-mentioned correction coefficient. By appropriately controlling and determining the correction coefficient, the corrected total mileage can be made longer or shorter than the actual total mileage. Details will be described later.

Peripheral information is information about a target object around the current position of the vehicle. Information about the target object includes information indicating the type of the target object and the distance between the current position and the target object. The type and distance of the target object are determined based on the map information stored in the database 19 and the vehicle position coordinates stored in the RAM. The driving state is information indicating the driving state of the vehicle. Driving states include meandering driving, sudden acceleration (including speed increase during driving and sudden start from a stop), sudden deceleration, right steep steering wheel, left steep steering wheel, low concentration driving, and drowsy driving. OBD information includes fuel consumption, fuel flow rate, vehicle speed, cooling water 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 the program such as firmware, the EEPROM stores the corrected total mileage until the previous engine stop, the driver's violation status, and the like. As for the corrected total mileage, when the engine is running and the radar detector 1 is operating, such as when the vehicle is running, the corrected total mileage up to that point is stored in the RAM as described above. Then, the corrected total mileage stored in the RAM when the engine is stopped is stored and held in the EEPROM. Violation status information is information about violations that occur while driving. The control unit 18 stores the content of the violation, the location where the violation occurs, and the number of times in association with each other.

(Function of control unit)
12 to 16 show a flowchart showing the function of the control unit 18. The main process is started 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 or not the operation of turning on the power of the radar detector 1 has been detected (S11). If the operation of turning on the power is not detected (S11: NO), the process returns to S11. When the operation of turning on the power is detected, the control unit 18 activates a fixed cycle process, which is an interrupt process that is activated at a predetermined cycle (S13). With the activation of the periodic processing, the control unit 18 reads the corrected total mileage stored in the EEPROM and stores the read corrected total mileage in the RAM.

(Periodic processing)
When the fixed cycle processing is started in S13 (see FIG. 12), the control unit 18 repeatedly executes the fixed cycle processing at a fixed cycle (for example, every 1 second). That is, the control unit 18 executes the main process and the fixed period process in parallel. This fixed cycle processing is as follows. As shown in FIG. 13, the control unit 18 first receives a GPS signal via the GPS receiver 13 (S31). The control unit 18 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 unit 18 executes a process of specifying the position of the target target existing around the vehicle (target position specifying process: see FIG. 14) (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 target 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 with the distance between the target object and the vehicle and stores it in the RAM as peripheral information (S55).

When the target target is not in the vicinity of the vehicle, or after the process S55 is executed, the control unit 18 has a signal corresponding to microwaves in the frequency band emitted from a speed measuring device that emits radar waves such as a mobile radar. , Receives the signal via the microwave receiver 14. In addition, the control unit 18 is a control radio, a car location radio, a digital radio, an extra small radio, a jurisdiction radio, a police telephone, a police activity radio, a wrecker radio, a heli-tele radio, a fire heli-tele radio, a fire-fighting radio, an emergency radio, and a highway radio. , Police radio, etc. (hereinafter, these are collectively referred to as "car location radio") are 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 or not a target target that emits a microwave or a radio signal exists nearby (S59). Specifically, the control unit 18 determines whether the signal is received via the microwave receiver 14 or the wireless receiver 15 and 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 a predetermined value, the control unit 18 determines that a speed measuring device that outputs the signal, a vehicle that outputs the car location radio (hereinafter referred to as an emergency vehicle for police, etc.) is nearby. (S59: YES). The control unit 18 identifies a device that outputs a signal (speed measuring device, emergency vehicle for police, etc.) based on the frequency of the signal. The control unit 18 stores information indicating the specified target target in the RAM as peripheral information (S61). As a result, the target position identification process (FIG. 13: S37) is completed, and the process returns to the fixed cycle 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 target for outputting the signal is the vehicle. It is determined that it is not in the vicinity of (S59: NO). As a result, the target position identification process (FIG. 13: S37) is completed, and the process returns to the fixed cycle process (FIG. 13).

* Calculation of total corrected mileage, etc. After the above target position identification process (FIG. 13: S37) is completed, the control unit 18 calculates the corrected total mileage and stores the calculated corrected total mileage in the RAM (S39). ). That is, the control unit 18 updates the storage area of the corrected total mileage of the RAM. Specifically, the control unit 18 is based on the history of changes in the vehicle position coordinates stored in the RAM, during the period from the execution of the previous fixed-period processing to the execution of the current fixed-period processing (for example, 1 second). Find the mileage and the correction coefficient this time. The control unit 18 obtains the corrected mileage during the execution cycle (for example, 1 second) of the constant cycle processing by the following formula.

Corrected mileage = correction coefficient x mileage

Then, the control unit 18 obtains the corrected total mileage in consideration of the current mileage by adding the obtained corrected mileage and the corrected total mileage stored in the RAM so far, and obtains the corrected total mileage. Record the distance in RAM. Further, the control unit 18 stores the obtained correction coefficient in the RAM as one of the correction information.

As shown in the above formula for obtaining the corrected mileage, when the correction coefficient is 1, the actual mileage and the corrected mileage are equal (see "solid line" in FIG. 17 (a)). Therefore, for example, the corrected mileage required when actually traveling 1000 km is 1000 km. On the other hand, when the correction coefficient is larger than 1, the corrected mileage is longer than the actual mileage (see “broken line” in FIG. 17 (a)), and when the correction coefficient is smaller than 1, the actual mileage is actually increased. The corrected mileage is shorter than the mileage of (see "One-dot chain line" in FIG. 17 (a)).

The correction coefficient may be determined, for example, based on the sensor output value (acceleration) of the acceleration sensor 22. 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 time correction coefficient, and the control unit 18 sets the correction coefficient to a predetermined value smaller than the normal time correction coefficient when the acceleration exceeds the threshold value. Then, when the normal state continues for a certain period of time, it is controlled to return to the original normal correction coefficient. Then, in the present embodiment, a small predetermined value when the acceleration exceeds the threshold value is set to "0", and the return to the normal correction coefficient is gradually returned over a predetermined period (FIG. 17 (b)). reference). Specifically, the control unit 18 calculates the correction coefficient based on the following equation.

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

Here, m is the normal correction coefficient (value at which the asymptote converges).
L is the mileage after the acceleration exceeds the threshold value (actual mileage) The unit is meters d is the distance constant
(When the engine is on: 10
After reaction by accelerometer: fixed value greater than 10 eg 100)

In the above equation, m and d are fixed values and are stored in the correction information of the RAM. The control unit 18 performs from the execution of the previous fixed-cycle processing to the execution of the current fixed-cycle processing each time the fixed-cycle processing is executed, that is, based on the history of changes in the vehicle position coordinates stored in the RAM every second. The mileage between (for example, 1 second) is calculated. The control unit 18 reads out the mileage for a predetermined period stored in the correction information storage area of the RAM, adds the mileage for the current time obtained above, and obtains the value of L. The control unit 18 uses the obtained L value and the m and d values stored as the correction information of the RAM, and substitutes them into the above equation to calculate the correction coefficient. Further, the control unit 18 updates the mileage for a predetermined period stored in the correction information storage area of the RAM to the value of L obtained this time.

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

Further, since the L value is stored in the correction information storage area of the RAM, the stored data disappears when the engine is stopped, and the L value is also reset to 0 when the engine is turned on. Therefore, by setting the value of d to 10 as the engine is turned on, the value of L becomes sufficiently larger than d immediately after the start of running, and the correction coefficient becomes m of the normal correction coefficient immediately. There is. On the other hand, once the acceleration exceeds the threshold value and the correction coefficient 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 steering wheel (right steering wheel / left steering wheel) can be detected individually based on the output of the acceleration sensor. Therefore, a threshold value 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 value.

Driving in which the acceleration exceeds the threshold corresponds to either sudden acceleration / deceleration or sudden steering, which is not only dangerous driving but also uncomfortable for the character on board. Not good mentally. Therefore, in the present embodiment, the correction coefficient is reduced so that the intimacy is unlikely to increase when the operation exceeds the threshold value, and the normal correction coefficient is not restored for a certain period of time. ing.

As described above, in the present embodiment, once the setting condition (here, the threshold value of acceleration) is not satisfied and the correction coefficient becomes small, even if the setting condition is satisfied immediately after that, it is not returned immediately but is predetermined. During the period, the correction coefficient was kept low. This is because, for example, in an unfavorable driving state such as dangerous driving in which the acceleration exceeds the threshold value, if it occurs even momentarily or for a short time, an accident or the like may occur, so it is better not to be in such a state during the driving period. Therefore, the driver will try to drive so as not to satisfy the set conditions even for a momentary time, and the set conditions can contribute to safe driving and the like, which is preferable. Further, if the setting condition is not satisfied even once, even if the driving that satisfies the setting condition is performed after that, the original state is not restored until a certain period of time elapses, which is a penalty and a game element may appear.

As will be described later, this increase in the corrected total mileage is associated with an increase in intimacy. Therefore, if the degree of increase in intimacy based on the actual increase in mileage, that is, the amount of change in which the intimacy increases when the correction coefficient is 1, is defined as the "reference change amount", the larger the correction coefficient is, the more the reference. 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 increase in intimacy with running 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 amount of change in intimacy due to running is larger than the reference amount of change because the operation is continued so that the acceleration does not exceed the threshold value. Can be maintained, and the situation becomes high intimacy quickly with a short mileage.

For example, the smaller the threshold value, the larger the value of the normal correction coefficient, and conversely, the larger the threshold value, the smaller the setting. In other words, if the threshold value is small, the sensitivity becomes high and there is a high possibility that even a small speed change (relatively small acceleration) will exceed the threshold value and reset L to 0, but if the vehicle can run below the threshold value, the total correction will be completed in a shorter period of time. The mileage can be increased and the intimacy can be increased. On the other hand, if the threshold value is large, the sensitivity becomes low and the threshold value is not exceeded even with a slight change in speed (relatively large acceleration). Therefore, the correction coefficient is lower than the normal correction coefficient for a certain period of time as L is reset to 0. Although the negative assessment control does not occur, the correction coefficient is originally small even when traveling below the threshold value, so the increase in the corrected total mileage is low as the vehicle travels. Therefore, the user may set the threshold value according to his / her driving situation, the driving road condition, and the like.

If the setting condition (threshold value) is made strict, there is a demerit that the value of the correction coefficient is small for a certain period without satisfying the setting condition due to a slight mistake in driving operation, or the correction coefficient is satisfied if the setting condition is satisfied. The coefficient continues to be large, the degree and degree of goodness of the relationship increases in a short period of time, and various character information according to the relationship can be obtained. Therefore, it becomes like a high risk and a high return, and the game quality is increased. In addition to simply increasing the gameplay, driving that meets stricter setting conditions usually results in a safer and more environmentally friendly driving state, such as safer driving or eco-driving. Since it is often the case, it is also preferable for the traffic environment.

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

* Identification of intimacy The control unit 18 specifies intimacy based on the corrected total mileage (S40). Intimacy is a parameter determined according to the corrected total mileage. The control unit 18 assumes that the intimacy of the character with respect to the driver increases as the total corrected mileage of the vehicle increases, and expresses the degree of intimacy as the intimacy. Specifically, the intimacy is determined as follows. If the total mileage is less than the first reference distance (for example, 100 km) since the radar detector 1 was first activated, the intimacy becomes 0. When the total mileage of the vehicle in the state where the character mode is set is 100 km or more and less than 1000 km, the intimacy becomes 1. Further, when the total mileage of the vehicle in the state where the character mode is set is 1000 km or more and less than 2000 km, the intimacy becomes 2. Further, when the total mileage of the vehicle in the state where the character mode is set is 2000 km or more, the intimacy becomes 3. The control unit 18 stores the obtained intimacy in the RAM.

This intimacy is an index showing the degree of relationship with the character, and the better the relationship, the larger the numerical value. In the present embodiment, the intimacy is leveled up in four stages such as 0 → 1 → 2 → 3. The intimacy is a condition for determining the character information output via the output device as described later. The better the relationship, that is, the higher the intimacy value, the more the output character information will be a kind of reward that jumps into variation, is familiar to the user, and makes the user happy. ..

As information for improving the relationship, that is, for increasing the intimacy, the mileage is the basis, and in principle, the longer the mileage, the higher the intimacy. For example, assuming that the character has a personality and emotion, the longer the mileage, the better the relationship between the driver and the longer the distance to drive with the character. Therefore, for example, if the mechanism is such that the relationship becomes better as the driver drives safely, the user can maintain the relationship with the character in a good song, and the degree of goodness is further increased. In addition, you will actively try to drive safely.

(Specification of driving conditions, etc.)
Next, the control unit 18 executes a process of specifying the driving information of the vehicle (driving state specifying process, see FIG. 15) (S41). As shown in FIG. 15, the control unit 18 acquires the acceleration detected by the acceleration sensor and the vehicle speed among the OBD information stored in the RAM (S71). Next, the control unit 18 determines whether or not the vehicle is in a predetermined driving state based on the acquired acceleration and vehicle speed (S73). Specifically, the control unit 18 has (a) meandering operation, (b) sudden deceleration, (c) sudden acceleration, (d) right-hand steering wheel, (e) left-hand steering wheel, and (f) concentration-reducing operation. (G) It is determined based on the acceleration and the vehicle speed whether the vehicle is being driven in any of the drowsy driving states. The judgment method is as follows.

The number of occurrences of each state in which the forward acceleration of the vehicle is 0.3 G or more, the rear acceleration of the vehicle is 0.15 G or more, and the left-right acceleration of the vehicle is 0.45 G or more. If the condition that the total is generated 15 times or more in 15 minutes is satisfied, the control unit 18 determines that (a) meandering operation is being performed. Further, the control unit 18 determines that (b) sudden deceleration has been performed when the acceleration in the front direction of the vehicle is 0.3 G or more. The control unit 18 determines that (c) sudden acceleration has been performed when the acceleration in the rear direction of the vehicle is 1.15 G or more. The control unit 18 determines that (d) the sudden right steering wheel has been performed when the leftward acceleration of the vehicle is 0.45 G or more. The control unit 18 determines that (e) the sudden left steering wheel has been performed when the acceleration of the vehicle in the right direction is 0.45 G or more. Further, 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 more, the control unit 18 performs (f) concentration reduction operation. Judge that it is broken. 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) doze driving 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 control unit 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 the driving state (S73: YES). S75). Then, the operation state specifying process is completed, and the process returns to the fixed cycle process. On the other hand, when the operating state does not correspond to any of the above (S73: NO), the control unit 18 ends the operating state specifying process and returns to the regular cycle process.

As shown in FIG. 13, after the operation state identification process (S39) is completed, the control unit 18 has stored peripheral information in the RAM in S55 (see FIG. 14) and S61 (see FIG. 14), or S75 (see FIG. 14). (See FIG. 15) to determine whether the operating state is stored in the RAM. If any of them is stored in the RAM, the control unit 18 determines that an event for notifying the driver has occurred (S43: YES). The control unit 18 turns on the event flag (S45). The fixed cycle processing ends. On the other hand, when neither the peripheral information nor the operating state is stored in the RAM (S43: NO), the event for notifying the driver has not occurred, so the control unit 18 turns off the event flag. (S47). The fixed cycle processing ends.

As shown in FIG. 12, after starting the fixed cycle 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 the information corresponding to the set display mode from the output information of the database 19 and outputs the device. Output from. As a result, the control unit 18 performs a well-known normal operation operation (alarm notification, 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).

Character mode processing will be described with reference to FIG. The control unit 18 reads the logo information stored in the database 19 and displays the logo screen on which the logo information is drawn 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 and the like have already been specified in the fixed cycle process started in S13 (see FIG. 12) and the information is stored in the RAM (S85). In the regular cycle processing, the current date and time, the position information of the vehicle, the mileage, etc. are specified by receiving the GPS signal which is the radio signal from the GPS satellite, so depending on the radio environment, the GPS signal may not be received immediately after the start. is there. Therefore, the time required to specify the current date and time is not constant and may take time. If the current date and time are not stored in the RAM, the current date and time have not yet been specified (S83: NO).

In this case, the control unit 18 displays the wallpaper screen 73 on which the character 104 lies on the display unit 5 as shown in FIG. 18 (S85). If the current date and time are not specified, the mileage and thus the corrected total mileage cannot be calculated and the intimacy cannot be specified. Therefore, the wallpaper screen 73 is displayed to notify that the state is undecided. The process returns to S83. As a result, the control unit 18 continues to display the wallpaper screen 73 until the current date and time and the like are specified. The current date and time includes a history of vehicle position information other than the current date and time, but if the current date and time is stored in the RAM, GPS signals can be received, so the judgment of S83 is limited to the current date and time. May be based.

When the current date and time, the position information of the vehicle, and the like are specified in the fixed cycle processing and the information is stored in the RAM (S83: YES), the control unit 18 reads out the still image information stored in the database 19 and displays the display unit 5. Is displayed in (S86). As a result, for example, as shown in FIG. 19, a still screen 72 showing how the character 104 is dressed in sunny clothes is displayed on the display unit 5. The still screen information includes a total of 12 still screens that differ from month to month. Each still screen reflects the seasonal scene. When reading the static screen, the control unit 18 extracts this month from the current date and time information, selects the static screen of the month corresponding to the extracted month from the static screen information stored in the database 19, and displays the display unit. Display in 5.

In this way, the radar detector 1 switches the still screen displayed on the display unit 5 according to the date and time, thereby preventing the driver from getting bored with the still screen. The radar detector 1 also makes the driver want to see a new static screen. Here, for example, the control unit 18 may control the display unit 5 so as not to display a new static screen when the driver performs dangerous driving or the like. As a result, the driver will try 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 lapse of a predetermined time from displaying the still screen on the display unit 5, the control unit 18 reads out the activation screen included in the activation information stored in the database 19 and displays it on the display unit 5 (S87). Further, the control unit 18 reads the start-up voice included in the start-up information and outputs it from the speaker 16 (S87).

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

FIG. 21 shows in detail the character voice corresponding to the time zone 7:00 to 10:00. If the intimacy stored in the RAM is 1, "Good morning. How are you doing?" "Now, do your best at work. I will do my best." "Good morning. Drive safely today. Please, please. ”, The character voice is a little unfriendly. The character expression mode for the driver is the first face-to-face mode. On the other hand, if the intimacy is 2, "Good morning. How are you doing?" "Every day, it's not all fun, but do your best." "Oh, good luck. Please drive carefully today." In addition, the character voice is intimate as compared with the case where the intimacy is 1. The character's representation to the driver is a normal friendship. Furthermore, if the intimacy is 3, "Good morning! Hey, I've been waiting for a long time since I woke up." "Wow! I'm glad I can be with you today." "Good morning! Fashionable today. Isn't it? I also want new clothes ~ ", and the character voice is even more intimate than when the intimacy is 1 or 2. The character's expression mode for the driver is a tame-mouth friend-like mode.

As described above, the radar detector 1 outputs a more intimate character voice as the intimacy increases, thereby increasing the intimacy of the character with respect to the driver according to the intimacy. By feeling that the intimacy of the character is gradually increasing, the driver gradually increases the familiarity with the character and strongly embraces the character.

Further, although not shown, the character voices when the time zone is from 5:00 to 7:00 are compared for each intimacy. If the intimacy is 1, "Good morning, I'm sorry." "Good morning. I'll do my best to alert you today." "I'm getting up early. I'm impressed." It has become. When the intimacy is 2, the character voice is similar to the character voice of "Ah? Is it already morning?", "It's not good yet! It's sleepy.", "Thank you for getting up early." If the intimacy is 3, "Good morning, I'm sorry." "Oh, I'm still sleepy. One minute left." "Good morning, I have to do my best to alert you today. For you. It is a character voice such as "Ni.". By listening to the sleepy voice of the character, the driver feels as if the character is a real creature. In addition, the driver feels sorry for waking up the character. The radar detector 1 further enhances the degree of emotional transfer to the driver's character by causing the user to have such emotions.

In the above description, an example of switching the character voice for each activation time has been described, but the character image can also be switched for each activation time. For example, in the time zone from 0:00 to 5:00, a character image of an expression mode in which the character is sleeping on the bed is associated. The driver has an intimate feeling toward the character by watching the character go to bed. The radar detector 1 further enhances the degree of emotional 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. This makes the driver feel as if the character really exists. In this way, the radar detector 1 can increase the degree of emotional transfer to the driver's character. Moreover, the output character information is a kind of reward that flies to variations as the intimacy increases, and that makes the driver familiar and happy. Therefore, the driver has a strong desire to maintain a good relationship so as to receive a reward, or to perform an operation / driving so that the relationship becomes better. Therefore, it can be expected that the driver will drive with a high degree of intimacy. That is, in the present embodiment, the increase in intimacy is not only a simple increase in mileage, but the amount of change with respect to a predetermined mileage changes based on information on the running of the vehicle, for example, whether or not the acceleration exceeds the threshold value. Control is performed so that when the vehicle is driven with an acceleration exceeding a set threshold value, the increase in the corrected total mileage that determines the intimacy is reduced over a certain period of time. Therefore, the driver will try to drive so 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.

Further, in order to increase the intimacy, that is, the corrected total mileage, it is not enough to simply increase the mileage, but information on the running of the vehicle (acceleration in the present embodiment) is also taken into consideration. For example, when the correction coefficient never exceeds the threshold value and becomes 0 during driving, the total corrected mileage can be earned and the feeling of clearing the mission can be obtained, which is preferable. Clearing such a mission is not just a game in virtual space, but a game with a new sensation that occurs with actual driving. And even if the actual driving of the vehicle is given a game-like property, clearing the mission will drive safely so as not to change the speed (increase / decrease speed) so that the acceleration value becomes less than the threshold value or suddenly change the direction. Since it is necessary, there is no problem in the conventional wisdom. This point also applies to the output of character information based on the intimacy shown below.

In the activation information of FIG. 20, the character voice is not associated with the intimacy: 0. When the intimacy 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 raises the expectation that he / she wants to start intimate communication with the character as soon as possible. The radar detector 1 uses such a 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 out the character information from the standby information of the database 19 and outputs it from the output device (S91). The character information is information output from the output device when the radar detector 1 operating in the MAP display mode-character mode is in the standby state. The details of the character information will be described with reference to FIGS. 22 and 23. As shown in FIG. 22, the character information includes a character image and a character voice. Character images and character sounds are classified according to intimacy. Note that "intimacy 1-3" in FIG. 22 indicates that different character images and character sounds are associated with each intimacy.

A plurality of character images and character sounds are prepared for each expression mode so that the character can communicate with the driver in various expression modes. Specifically, the character information includes character images and character sounds corresponding to each of (1) blinking & lip-synching, (2) blinking only, (3) walking, and (4) stretching. ing. For example, (1) When a character image corresponding to blinking & lip-syncing is displayed on the display unit 5, the character blinks and moves his / her mouth as if he / she is speaking something. Further, for example, (3) when the character image corresponding to the 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, when the character image corresponding to (4) stretching is displayed on the display unit 5, the character stretches. 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) blinking & lip-synching. If the intimacy is 1, "Do you like driving? I don't hate your driving." "Oh, thank you for bringing me to your car!" Familiar character voices are associated. On the other hand, if the intimacy is 2, "Hey, did you like me? I also like you!" "When you drive, you look pretty serious, huh?" As described above, a more intimate character voice is associated with the case where the intimacy is 1. Furthermore, if the intimacy is 3, "I'm happy every day because you talk to me!" "Hey, I really want to talk more. I want to know more about you." Compared with the cases where 1 and 2, more intimate character voices are associated with each other. When the character voice is output from the speaker 16, one of the plurality of character voices associated with the intimacy: 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 outputs a more intimate character voice as the intimacy increases, thereby increasing the intimacy of the character with respect to the driver according to the intimacy. By feeling that the character's intimacy with the character is gradually increasing, the driver gradually increases the familiarity with the character and strongly embraces the character.

Further, the radar detector 1 constantly 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 the standby state where no event occurs. This causes the driver assistance system 4 to make the driver feel as if the character were a real creature and always beside him. Since the driver feels close to the character, the degree of emotional empathy for the character is further increased.

Further, the radar detector 1 prepares a plurality of character images and character sounds, randomly selects them, and outputs them from an output device. This prevents the communication by the character from becoming monotonous and prevents the driver from getting tired of communicating with the character.

In FIG. 22, only the character image is assigned to the intimacy: 0, and the character voice is not associated with it. Therefore, when the intimacy is 0, the character image is displayed on the display unit 5, and the character sound is not output from the speaker 16. Since the driver cannot hear the character voice when the intimacy is low, he / she has an expectation that he / she wants to recognize not only the character image but also the voice. The radar detector 1 uses such a driver's psychology to further increase the degree of emotional 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 it the timing for the control unit 18 to output the character information (see FIG. 24, which will be described later)? Is determined (S93). The character information is information output to an output device when an event occurs in the radar 1 operating in the MAP display mode-character mode. The determination method and the details of the output information will be described later. When the control unit 18 determines 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, when the control unit 18 determines that it is not the timing to output the character information (S93: NO), the process proceeds to S97.

The method for determining whether to output the character information in this event information and the output character information are as follows. FIG. 24 shows the details of the character information in the event information. The character information includes a character image and a character sound. A plurality of character images and character sounds are prepared for each expression mode. In FIG. 24, (1) go to bed, (2) get up, (3) sleep while sleeping, (4) be careful of overspeed, (5) get drunk, (6) sudden deceleration, (7) sudden Acceleration, (8) Right steering wheel, (9) Left steering wheel, (10) Angry and disappearing when the degree is over, (11) Angry subsides and returns, (12) Napping, (13) Awakening, (14) Loss of concentration, (15) drowsy driving, (16) orbis, crackdown, inspection warning, (17) radar, car location reception warning, and (18) character images and character sounds corresponding to other target targets are intimacy: 1 It is associated with -3. Similar to the character information in the standby information shown in FIG. 22, the character voice corresponding to the intimacy: 0 is not included in the character information in this event information. Therefore, when the intimacy 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) Go to bed" is information to be output when the radar detector 1 is activated between 22:00 and 0:00. When the character image is displayed on the display unit 5, the character goes to bed at a timing one minute after the activation of the radar detector 1. The control unit 18 uses a voice to inform the driver of going to bed as information indicating the time of going to bed ("It was fun today-take me a drive again tomorrow." "I will go to bed. You will go to bed properly." If you don't have it, you can't do it. Good night ”etc.) is selected according to the intimacy and output from the speaker 16 as character voice. Further, after going to bed, the control unit 18 periodically outputs the sleeping breath of the character as the character voice from the speaker 16.

For example, the character information corresponding to "(2) Wake up" is information to be output when the radar detector 1 is activated between 5:00 and 7:00. When the character image is displayed on the display unit 5, the character wakes up at a timing one minute after the activation of the radar detector 1. As information indicating the time of waking up, the control unit 18 informs the driver of waking up ("Good morning. Alarm resumes Mars" "Good morning. I'm glad I can be with you today!", Etc.) Is selected according to the intimacy, and is output from the speaker 16 as a character voice.

For example, the character information corresponding to "(3) Sleep-talking while sleeping" is information that is randomly output in a cycle of 5 minutes every 10 to 30 minutes while the character is sleeping. The control unit 18 performs an animation in which the character moves his / her mouth when the character image is displayed on the display unit 5 as information indicating the sleeping talk during sleep. In addition, the control unit 18 selects sleep-talking (“Beautiful stars”, “Re, please be full, please”, etc.) according to the intimacy, and at the timing when the character moves his mouth. It is output from the speaker 16 as character voice.

As described above, in this system, character information is output in an expression mode as if the character is a real creature. The driver will feel as if the character is real. In this way, the system can increase the degree of emotional transfer to the driver's character.

For example, the character information corresponding to "(4) Caution for overspeed" is information to be output when the vehicle speed exceeds the speed limit. The control unit 18 identifies the vehicle speed based on the OBD information stored in the RAM, and determines the speed limit based on the vehicle position coordinates stored in the RAM and the map information stored in the database. The speed limit is the speed limit of the road currently running or the speed limit of the installation position of the speed measuring device existing in the vicinity. The control unit 18 compares the value obtained by adding a predetermined traveling speed (for example, 10 km / h) to the determined speed limit with the vehicle speed, and outputs character information for cautioning that the vehicle speed is excessive when the vehicle speed is faster. When the character image is displayed on the display unit 5, the control unit 18 notifies the driver, for example, the current vehicle speed and the speed limit, and causes the driver to decelerate. Output an animation that prompts you. In addition, the control unit 18 responds to the intimacy with a voice notifying the overspeed ("Hey! Isn't the speed coming out? It's dangerous", "Hey, I hate people who overspeed!", Etc.) Is selected and output from the speaker 16 as character voice. This allows the driver to easily recognize that the traveling speed of the vehicle exceeds the speed limit. Since the degree of emotional empathy of the driver with respect to the character is strong, the driver pays attention to safe driving by obediently responding to the notification from the character and decelerating.

For example, the character information corresponding to "(5) Get drunk" is output when the event flag stored in the RAM is turned on and the information indicating meandering driving is stored as the driving state. .. In such a case, it is highly possible 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 in which the character behaves as if he / she feels sick due to motion sickness. In addition, the control unit 18 listens to the character's painful voice ("Hmm, hmm, I'm a little sick, I'm sorry", "I'm drunk because I'm driving like that. It is selected according to the density and output from the speaker 16 as character voice. As a result, the driver feels sorry for the character's motion sickness and tries to drive slowly and politely. In this way, the system can encourage the driver to drive politely.

For example, for the character information corresponding to "(6) Sudden deceleration, (7) Sudden acceleration, (8) Right steering wheel, (9) Left steering wheel", the event flag stored in the RAM is ON and driving. This is information that is output when information indicating sudden deceleration, sudden acceleration, right-hand steering wheel, and left-hand steering wheel is stored as a state. This is because when the driver drives by such a driving method, there is a high possibility that the vehicle will 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 staggers in the direction of the detected acceleration. In addition, a voice notifying the driving method (sudden deceleration: "Kyaa! I was about to fall. I'm going to get angry next time?" --- I! Mmm, I hit my head! I saw it !? "" It's dangerous to start suddenly! You won't do it anymore? "" Hey, you didn't mistake the brake for the accelerator, right ?? " : "Turn the steering wheel a little more slowly-the eyes turn around" "Cha-ya-ah, did you look forward? I thought I'd fall down." "I can't believe it! It is selected accordingly and output from the speaker 16 as character voice. As a result, the driver becomes aware that he / she is driving violently and dangerously, and tries to drive politely. By giving such a warning, this system can prevent the occurrence of a traffic accident.

For example, in the character information corresponding to "(16) Orbis, crackdown, inspection alarm", the event flag stored in the RAM is turned on, and the radar type Orbis, H system, LH system, and loop coil (hereinafter, these are used). Information indicating the Orbis) is stored in the RAM as peripheral information, and the information indicating the distance between the Orbis and the vehicle is a predetermined distance (for example, 2100 m, 1100 m, 600 m). Is output to. Alternatively, it is output when the event flag 38 stored in the RAM is turned on and the information indicating the crackdown or inspection is stored as peripheral information.

For example, as for the character information corresponding to "(17) Radar, car location reception alarm", the event flag stored in the RAM is turned on, and the information indicating the speed measuring device or the emergency vehicle for police is stored in the RAM as peripheral information. Output when stored.

The character image corresponding to these "(16) Orbis, crackdown, inspection warning" or "(17) Radar, car location reception warning" is displayed on the display unit 16 as follows. As shown in FIGS. 25 and 26, first, the clothing of the character 104 changes from white (FIG. 25) to black (FIG. 26). This change means that the character 104 has transformed. It is advisable to change the clothes of the character before and after the transformation, the animation motion, and the like according to the priority.

The transformed character 104 is superimposed on the display screen of the map 100 showing the surrounding target objects 105 as shown in FIG. 27, and as shown in FIG. 28, the orbis, the crackdown, the inspection, the speed measuring device, and the speed measuring device. It provides the driver with information 74 indicating one of the police emergency vehicles and a distance 75 between the vehicles. In addition, a voice to notify the driver of the displayed contents ("Emergency situation, radar orbis found 2000 meters away." "The distance is approaching 1000 meters! Radar type orbis" "500 meters remaining ~, taking a picture "Don't do it ~" etc.) is selected according to the intimacy and output from the speaker 16 as character voice.

As described above, the radar detector 1 as a driving support system can recognize that the target object for monitoring traffic is near the vehicle by receiving the radio signal transmitted from the target object. The device for monitoring traffic is often installed in a place where a traffic accident is likely to occur or in a place where an accident has occurred in the past. Therefore, the radar detector 1 notifies the driver that the target target for traffic monitoring is near the vehicle, thereby making the driver aware of the place where a traffic accident is likely to occur, and driving particularly safely in such a place. Can be encouraged to keep in mind.

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

In addition, since the driver is notified by the character voice that the distance between the object to be monitored for traffic and the vehicle is approaching, the radar is used even when the driver is not looking at the display unit 5. The detector 1 can surely make the driver recognize that the vehicle is approaching the Orbis or the like.
Although a specific description is omitted, character information is output according to the intimacy of other expression modes.

As shown in FIG. 16, the control unit 18 determines whether or not the driver has detected the setting operation on the radar detector 1 (S97). When the control unit 18 detects that the driver touches the display unit 5 in the standby state via the touch panel 6, it determines that the driver has performed the setting operation (S97: YES), and the control unit 18 determines that the driver has performed the setting operation. The setting screen is displayed on the display unit 5 based on the setting screen information stored in the database 19. Further, the control unit 18 sequentially switches the setting screen to be displayed on the display unit 5 according to the content of the setting operation by the driver, and stores the setting information set by the setting operation in the database 19 to set the setting information. (S99). When the control unit 18 executes the process based on the setting information, the radar detector 1 operates according to the setting of the driver. The process proceeds to S101. On the other hand, if the setting operation by the driver is not detected (S97: NO), the process proceeds to S101.

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

(Modified example with indicator)
FIG. 29 is an example of a display screen showing a modified example of the present invention. In this modification, a display area for displaying the current correction coefficient is provided. That is, as shown in FIG. 29 (a), the correction coefficient display area 81 is provided on the left side of the main area for displaying the map 100 and the character 104. The correction coefficient display area 81 is an indicator that the light emitting area expands and contracts in the vertical direction. In the illustrated indicator, the substantially central position of the correction coefficient display area 81 in the vertical direction is set to "0", and the indicator extends upward as the value of the correction coefficient increases. The maximum value is 4 here. Further, as described in another modification described later, when the correction coefficient takes a negative value, the light emitting region of the indicator is in a display mode extending downward from the center position where the correction coefficient value is 0. That is, the indicator takes an aspect as shown in the schematic diagram as shown in FIG. 29 (b).

Further, especially when the correction coefficient can take a negative value, for example, "1" and "-1" both have the same length of the light emitting region, and the length is short, and the center in the vertical direction. Since it is located near, it is difficult to understand which value is at a glance. In particular, the driving driver cannot gaze at the display unit 5 for a long time, and it is necessary to check the display contents of the map 100 and the character 104 in a short time, and display the correction coefficient display area 81. Coupled with the small area itself, it is even more difficult to recognize the current correction coefficient.

Therefore, the emission colors are 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. By doing this, even if a short light emitting area is displayed near the center in the vertical direction, the driver will be negative whether the current correction coefficient is positive or moderate in that color. You can intuitively understand whether it is in a very bad state. In addition, red means "stop" at traffic lights and often means prohibition even at traffic signs, while blue means "advance" at traffic lights and there is no particular prohibition on traffic signs, so traffic rules A driver who knows can understand that red is a reflexively unfavorable condition.

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

The read timing / cycle is preferably a short time (for example, 1 second). This is because the influence of the current driving situation on the correction coefficient 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. Then, when the light emitting area of the indicator disappears when the accelerator pedal or the brake pedal is stepped on, or when the steering wheel is turned by turning left or right or changing the course, the driver causes the acceleration to exceed the threshold value and the correction coefficient becomes 0. It is possible to know that, and from the driving situation immediately before, it is also possible to know which action the correction coefficient became 0 based on. Therefore, you can understand your driving habits (easy to start suddenly / easy to step on sudden brakes / easy to steer suddenly, etc.), reflect on what kind of driving operation you should be careful about, and the correction coefficient is Measures can be taken to drive without deterioration. Further, once the correction coefficient becomes 0, as shown in FIG. 17B, the correction coefficient gradually increases and returns to the normal correction coefficient. By updating the display of the indicator in a short period of time, it can be seen that the light emitting region of the indicator gradually expands and gradually returns to the normal correction coefficient. Therefore, it is preferable that the driver is happy to be able to confirm such a state and continues the operation while being careful not to exceed the threshold value as it is.

On the other hand, if the average for a long period is taken, it is difficult to achieve the above effect. That is, even if the correction coefficient drops to 0, the state does not appear immediately, and the driver cannot understand which driving operation caused the acceleration to exceed the threshold value, or is buried by the high correction coefficient before that. It may be difficult to recognize that the correction coefficient did not drop to 0 and the driver did not drive safely. Further, even if the correction coefficient drops once, it may return to the original state when the indicator display is updated next time, and it may not be possible to recognize the state of gradually returning.

Further, regarding the update cycle of the indicator, it is preferable to match the cycle of the constant cycle processing. This is because the correction coefficient is updated each time the constant cycle processing is executed and affects the correction mileage, so that the current correction coefficient can be known. The display processing of this indicator may be performed in parallel with the fixed-period processing, or may be performed as a fixed-period processing.

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

Therefore, as in this modification, the correction coefficient display area 81 (for example, an indicator) is used to notify the current correction coefficient, so that the driver can know the current correction coefficient, and the current driving method, You can immediately see how the amount of change is changed and reflected depending on the driving condition. Therefore, the driver can know, for example, what kind of driving operation is required to reduce or increase the correction coefficient. As a result, the driver can perform a driving operation such that the correction coefficient does not decrease or increases. In addition, by notifying the driver of the current correction coefficient, it is possible to motivate the driver to maintain the state as it is or to improve the correction coefficient.

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

Further, the notification of the current correction coefficient may change the appearance of the character according to the correction coefficient instead of the correction coefficient itself. Although specific illustration is omitted, for example, it is preferable to change the facial expression of the character. As an example of this change, the degree of smile may be further divided into a plurality of stages, such as "smiling"-> "normal"-> "looking lonely"-> "feeling stuffy". Also, if it is difficult to understand only the facial expressions, it is better to add animation movements. In either case, the character information corresponding to the information having a larger correction coefficient should be a kind of reward that is familiar to the user and makes the user happy. The correction coefficient notification function using the character's appearance may be executed independently or in combination with other notifications such as an indicator.

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

Specific settings are made using the internal data (FIGS. 30 (a) and 30 (b) and the input screen (FIG. 30 (c)) which is an interface for inputting the setting conditions by the control unit 18 as shown in FIG. 30. That is, a table in which the sensitivity shown in FIG. 30A as internal data and the threshold value of each acceleration for each combination of four detection targets of sudden acceleration / deceleration, right steep handle / left steep handle, and FIG. 30 are associated with each other. It has a table that associates the sensitivity shown in (b) with each asymptote value for each combination of four detection targets. In this example, sudden acceleration / deceleration is divided into six sensitivity levels, and the left and right sudden handles are used. Is divided into four sensitivity levels. Further, the database 19 stores screen information of the matrix structure shown in FIG. 30 (c) as an input screen.

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 the main menu screen (not shown) on the display unit 5. When the control unit 18 detects that the acceleration sensor sensitivity selection button provided on the main menu screen is touched, the control unit 18 reads out the setting screen shown in FIG. 30 (c) and displays it on the display unit 5. The button area of the current setting condition is displayed in a different color from 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-hand steering wheel and the left-hand steering wheel is set to 3.

The sensitivity on this setting screen and each button area specified by the four detection targets are set to the corresponding areas of the acceleration sensor threshold value (FIG. 30 (a)) and the asymptote value (FIG. 30 (b)). Associated with a number. For example, taking the current selection state as an example, the sensitivity 4 of sudden acceleration is associated with an acceleration sensor threshold value of 0.4 and an asymptote value of 0.2. Similarly, the sensitivity 4 of sudden deceleration is associated with the threshold value of the accelerometer of 0.4 and the asymptote value of 0.2, and the sensitivity 3 of the left and right steep handles is gradually approached with the threshold value of the acceleration sensor of 0.5. A line value of 0.3 is associated. Under this setting condition, the correction coefficient becomes 0 when the acceleration in the front-rear direction exceeds the threshold value (0.4) in either one, and the acceleration in the left-right direction exceeds the threshold value (0.5) in either one. The correction coefficient becomes 0. In other words, if all accelerations in the four directions do not exceed the corresponding thresholds, the set normal correction factor is maintained. This normal correction coefficient is the sum of each asymptote value. 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 mileage and the corrected total mileage have the same increase amount.

On the other hand, in this modified example, since the sensitivities can be set individually for the four detection targets, for example, when it is detected that the button area insensitive to the sensitivity of sudden acceleration (for example, 2) is touched, the control unit 18 is shown in FIG. Accessing the data of the accelerometer threshold value shown in 30 (a) and the asymptote value shown in FIG. 30 (b), the accelerometer threshold value (0.5) associated with the touched sudden acceleration sensitivity 2 is asymptote. The linear value (0.1) is acquired and set in the corresponding area of the RAM. Then, since the acceleration threshold value for sudden acceleration is changed from 0.4 to 0.5, the probability of exceeding the threshold value becomes low, and the probability that the correction coefficient is reset to 0 decreases. On the other hand, under this setting condition, the correction coefficient at normal times is 0.9, so even if the driver does not exceed the threshold value, the corrected mileage is shorter than the mileage and the distance does not increase. On the other hand, when the sensitivity of the right-hand steering wheel 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 and the asymptote value stored in the RAM. Then, since the threshold value becomes smaller from 0.5 to 0.45, the possibility of exceeding the threshold value increases, but if the operation that does not exceed the threshold value is continued, the correction coefficient becomes 1.1 and the corrected mileage is higher than the actual mileage. Is larger. Further, when each asymptote value is set as shown in FIG. 30 (b), the maximum correction coefficient is 1.8 and the minimum is 0.2.

Since the input interface displayed to the driver is an input screen for designating the relative levels of a plurality of levels for each sensitivity as shown in FIG. 30 (c), the internal data shown in FIGS. 30 (a) and 30 (b). Even if the specific numerical values of (threshold value and asymptote value) are changed, the input screen seen by the driver does not have to be changed. Therefore, since the user interface does not change, the operability can be maintained in good condition. Then, the driver only has to specify a plurality of levels from "severe (difficult)" to "loose (easy)", and can intuitively specify the setting conditions. In addition, under the current setting conditions, if the conditions are often not satisfied, the setting conditions are loosened by one or more steps, and conversely, if the setting conditions are always satisfied, the setting conditions are set to be stricter by one or more steps. You can make adjustments to increase the amount of change, and you can easily set appropriate conditions.

Since the threshold value can be set individually in this way, the driver sets the threshold value in a combination that allows a high score (high normal correction coefficient) to be obtained while driving without exceeding the threshold value in any direction. it can.

For example, depending on various usage conditions such as the driving habits of the user, the characteristics of the vehicle, the condition of the road on which the vehicle is traveling, and the installation position of the machine equipped with this system, it may be possible to easily meet even strict installation conditions. , May not be possible. Therefore, by setting the setting conditions individually, it is possible to increase the normal correction coefficient while satisfying all the sets of setting conditions for the four detection targets. As a driving habit, in the case of a driver who does not change much in speed but makes a sudden lane change, he / she is sensitive to sudden acceleration and deceleration (for example, 5 and 6), and is insensitive to left and right steering wheels (for example, 5 and 6). For example, set 1).

As for the characteristics of the vehicle, for example, in the case of a manual vehicle, it tends to start suddenly, so that the detection of sudden acceleration is insensitive, and the others are standard or sensitive. Further, more specifically, if the installation position of the acceleration sensor 22 in the vehicle is the center in the width direction of the vehicle from the installation position of the radar detector 1, the sensitivity of the left and right steep handles is the same, but the installation position is left and right. If it deviates to either one, the lateral force applied to the accelerometer differs between when turning right and when turning left. Therefore, it is preferable to make one sensitivity sensitive and the other sensitive insensitive.

(Modification example to restore the correction coefficient: Especially using the distance constant d)
In the above-described embodiment, the distance constant d is set to 10 when the engine is turned on. However, in the case of adopting a configuration in which the mileage L up to that point is stored even when the engine is turned off, since L has been a predetermined large value since the engine was turned on, it is not necessary to take measures to set it to 10.

Further, it is a fixed value when the acceleration exceeds the threshold value and L is reset to 0. In the above-described embodiment, one type of fixed value (for example, 100) is used, but the number of times the acceleration exceeds the threshold value is It is advisable to increase the distance constant d as it increases. For example, d after the first threshold is exceeded is 100, the second is 500, the third is 1000, the fourth is 5000, and the fifth and subsequent times are 10000. By changing d, the violation is repeated, and if it is malicious, the period required to return to the normal correction coefficient (here, the mileage) is long. In this way, as the number of times the acceleration exceeds the threshold value increases, the mileage required to return to the normal correction coefficient becomes longer, the correction coefficient becomes lower over a longer period of time, and the total corrected mileage increases (increases). The amount of change) becomes worse. Therefore, the driver can be expected to drive while being careful not to exceed the acceleration once the acceleration exceeds the threshold value.

This means that when the acceleration exceeds the threshold value, for example, the character who is also a passenger has feelings of being sick, uncomfortable to ride, and feeling depressed. Then, when such a state is repeatedly performed, the feelings toward the user when the character is given a personality and emotion become worse, and it takes a long time to recover the mood. Increasing the above d also shows a change in the character's feelings.

Further, in the above-described embodiment and the present modification, the mileage 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 mileage is reached. I made it. The present invention is not limited to this, and may be stepped and discretely ascended in a stepped manner, or a predetermined period (for example, traveling a certain mileage) may be set to a reduced low correction coefficient for the predetermined period. After the lapse of time, the correction coefficient may be returned to the normal correction coefficient at once. The constant mileage may be fixed or may be increased as the number of times the acceleration exceeds the threshold value increases as in this modification.

(Modification example of adjustment of correction coefficient 1: Adjustment due to overspeed 1)
In the above-described embodiment, the acceleration is used as the information associated with the running of the vehicle for which the negative assessment is performed to reduce the correction coefficient, but in the present embodiment, the vehicle speed is also added as one of the conditions. Specifically, if you are driving at a point where the speed limit is set and the vehicle speed exceeds the speed limit, it is a violation of the speed limit of the traffic rules, so make a negative assessment to reduce the correction coefficient. Do. In this case, it is often the case that the speed limit is slightly exceeded, and it is rather dangerous to drive while keeping the speed limit against the flow of surrounding vehicles. Therefore, in this modified example, as the first reference speed, which is a criterion for determining whether or not the speed is exceeded, not the speed limit itself, but a set speed higher than the speed limit is set. In other words, if the current vehicle speed exceeds the first reference speed, a negative assessment that the correction coefficient becomes smaller is performed, and even if the speed limit is exceeded, if it is below the first reference speed, the negative assessment due to overspeed is performed. Not performed. The set speed may be set to, for example, 20 km / h. For example, an excess speed of about several km / h is likely to occur as the vehicle goes downhill or the speed of surrounding vehicles increases as a whole. Then, when the surrounding vehicles are traveling at a speed limit or higher as a whole, if only the own vehicle is traveling while observing the speed limit, a dangerous state is caused. Therefore, by setting so that the negative assessment control for the correction coefficient does not occur even if the speed is slightly exceeded, it is possible to drive in accordance with the flow of surrounding vehicles. 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 standard for increasing the risk because if the speed limit exceeds 20 km / h, the number of violation points at the time of traffic violation will be 2 points. Therefore, the set speed was set to 20 km / h and a negative assessment was performed.

Further, the control for reducing the correction coefficient based on the acceleration is such that 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 or the degree to which the threshold value is exceeded. However, the adjustment control associated with the overspeed in this modification changes the effect of reducing the correction coefficient according to the magnitude of the overspeed. It can be said that overspeed is malicious because the risk of overspeed increases as the excess speed from the speed limit increases, even if it is the same overspeed violation. Therefore, the greater the degree of violation (excess speed), the lower the effect of the decrease in the correction coefficient, that is, the lower the growth rate of the corrected total mileage due to actual driving. Specifically, the control unit 18 acquires the current position information of the vehicle stored in the RAM, acquires the speed limit set at the current position from the map information stored in the database 19, and obtains the first reference. Find the speed (speed limit + set speed). Further, the control unit 18 acquires the vehicle speed from the OBD information recorded in the RAM, and determines whether or not the vehicle speed exceeds the first reference speed. When the first reference speed is exceeded, the control unit 18 calculates the correction coefficient based on the following equation (1).


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

Here, m is the normal correction coefficient (value at which the asymptote converges).
L is the mileage after the acceleration exceeds the threshold value (actual mileage) The unit is meters d is the distance constant
(When the engine is on: 10
After reaction by accelerometer: fixed value greater than 10 eg 100)
k is the velocity coefficient (eg 0.0025)
v is the excess speed (vehicle speed-first reference speed)

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

For example, when traveling at 81 km / h at a point where the speed limit is set to 60 km / h, the first reference speed is exceeded, so the correction coefficient is obtained using the above equation (1). Further, 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". Assuming that L is sufficiently large, the correction coefficient obtained by the equation (1) is substantially equal to the value of M. Therefore, the larger the excess speed v, the larger the absolute value of the correction coefficient. If the value of L is not sufficiently large, the absolute value is smaller than M as in the acceleration in the above-described embodiment, but the tendency that the absolute value of M increases as the excess speed v increases is the same.

Since the correction coefficient takes a negative value, the total corrected mileage decreases as the vehicle runs beyond the first reference speed. Then, since the correction coefficient is obtained in consideration of the excess speed v, the degree of decrease in the corrected total mileage when the excess speed v is 5 km / h is larger than that when the excess speed v is traveled by the same distance. Then, 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, the vehicle speed is equal to or less than the first reference speed, so the control unit 18 obtains a correction coefficient based on the above equation (2). Since this correction coefficient takes a positive value, the total corrected mileage as the vehicle travels 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.

Further, in the above modified example, 20 km / h is shown as an example of the set speed. This set speed may be a fixed value or may be switched according to another condition. Another condition is, for example, the speed limit of a highway. 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 an expressway 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 set to a speed higher than the speed obtained by adding the set speed to the speed limit regardless of the speed limit. This high speed is, for example, 100 km / h.

For example, there are some such as the Metropolitan Expressway where the speed limit is set to 60 km, which is slower than the speed limit of general expressways. On such a highway with a slow speed limit, surrounding vehicles 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, but if only the own vehicle is traveling at the speed limit of 60 km / h, the speed difference from other vehicles becomes 30 to 40 km / h, which is dangerous. Therefore, safe driving can be promoted by preventing a negative assessment based on overspeeding from occurring even when driving according to the surroundings.

(Modification example of adjustment of correction coefficient 2: Adjustment due to 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 stop sign violation. When the stop violation is violated, the control unit 18 subtracts a predetermined value from the current correction coefficient to obtain the correction coefficient. Since the predetermined value is subtracted, the obtained correction coefficient may be negative. Furthermore, when the suspension violation is performed multiple times at the same point, the predetermined value to be subtracted is increased. Repeating the same type of violation multiple times at the same place is not only lacking in attention, but it can also be said to be a worse violation than the first time. The increase in the corrected total mileage as the distance increases is reduced. In this way, the user can be expected to drive while trying not to violate the traffic.

Furthermore, in the case of the first suspension violation, a grace period is given without subtracting the correction coefficient, although a warning is given. As a result, since the correction coefficient does not decrease in the first violation, the motivation of the driver is not lowered, and caution is taken not to make a violation in the second, and as a result, safe driving can be promoted. In addition, as a warning in the case of the first violation, for example, immediately after making a stop violation, voice information such as "You didn't stop, please stop this time" was output, or the stop was not stopped. If you go to the place after that, it is good to output a warning by voice information such as "You didn't stop last time, please stop this time" from the speaker 16 before that. It is advisable to change the output voice warning message according to the intimacy.

In this way, if you make a pause violation, the correction coefficient will not be lowered immediately from the first time, but as a warning, you will be notified that the correction coefficient will be lowered if you make the same type of violation next time, and then correct if you make the same type of violation next time. It is advisable to lower the coefficient. Instead of suddenly lowering the correction coefficient, it is possible to urge the user not to violate by warning. If the same violation is made despite the warning, the advice from the character is ignored and the correction coefficient is controlled to be lowered.

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 pauses existing in the surroundings. 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 or not the vehicle has been properly paused at the pause location. Since the fixed cycle processing is performed every second, it is determined whether or not the vehicle speed has been maintained, depending on whether or not the state where the vehicle speed is 0 continues for a plurality of cycles.

If it has not been paused, the control unit 18 searches the violation status stored in the EEPROM, determines whether or not there is a pause violation for the same location, and if not, the first time at the same location. The location information of the place where the suspension was not performed and the number of violations (1) are stored. If there is a record of a suspension violation at the same location, the number of violations associated with it is read and incremented by 1, and the information on the number of violations in EEPROM is updated to a new number.

Then, the control unit 18 obtains the acquired number of violations (1 for the first time, and 1 increment of the number of violations read from the EEPROM if there is a violation history in the past), 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 the normal correction coefficient (value at which the asymptote converges).
L is the mileage after the acceleration exceeds the threshold value (actual mileage) The unit is meters d is the distance constant
(When the engine is on: 10
After reaction by accelerometer: fixed value greater than 10 eg 100)

s is a temporary stop deduction coefficient Number of violations at the same location 1st time: 0
Number of violations at the same location Second time: 0.5
Number of violations in the same place 3rd: 1
Number of violations at the same location 4th or more: 2
τ is the mood recovery time constant 600 (complete recovery in 10 minutes)
t is the elapsed time (seconds) since the suspension violation

In the above equation, 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 suspension violation. In the case of the first violation, no points are deducted because the suspension deduction coefficient s is 0. Since t is 0 at the time of the suspension violation, the suspension deduction coefficient s is subtracted from the current correction coefficient. Then, as the number of times increases, the pause deduction coefficient s increases, so that the correction coefficient is also largely subtracted to a small value. For example, even if the normal correction coefficient is 1 or 1.2, which is the standard, the correction coefficient becomes negative at once because the pause deduction coefficient s is 2 after the fourth and subsequent violations at the same location. Even if the number of violations at the same location is the third, the correction coefficient becomes a negative value when the normal correction coefficient is set as low as 0.8. Further, even in the second time or the like, if a pause violation is made in a section where the correction coefficient is small due to 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 mileage decreases as the mileage increases. Therefore, the driver should try to pause properly at the place of suspension, and the driving will be safe.

The period affected by the deduction due to the suspension violation 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 also be changed depending on the number of violations. For example, the second recovery may take 10 minutes, the third recovery may take 30 minutes, and the fourth recovery may take 60 minutes.

(Modification example of adjustment of correction coefficient 3: Adjustment due to overspeed part 2)
In the above modification 1, when the first reference speed is exceeded, the correction coefficient takes a negative value. Therefore, when traveling below the first reference speed, the correction coefficient is a positive value, but when it exceeds the first reference speed even at 1 km / h, the correction coefficient drops to a negative value at once. On the other hand, in this modification 3, the correction coefficient is controlled to be reduced when the first reference speed is exceeded, but the value is set to a positive value. As a control for reducing the correction coefficient within the positive range, for example, L in the formula for obtaining the correction coefficient in the above-described embodiment (formula (2) in the deformability 1) is set to an appropriate value according to the excess speed v. Set to. In this way, the correction coefficient is once reset to 0 when the acceleration exceeds the threshold value, but in the case of deduction due to overspeed, it restarts from the value of the correction coefficient corresponding to L according to the overspeed v, and gradually It will increase. Further, a term of deduction due to overspeed may be separately provided as in the deduction due to temporary stop in the second modification.

Furthermore, the second reference speed that exceeds the first reference speed is set, and if the second reference speed is exceeded, the correction coefficient corresponding to the excess speed when the first reference speed is exceeded is lowered. It is good to lower it greatly. In this case, the second reference speed may be, for example, a speed (exceeding 30 km / h) that results in a one-shot suspension. It can be said that the state of overspeed, which is a one-shot suspension, is a very dangerous driving state that leads to a big accident. In such an operating state, the correction coefficient may be significantly reduced, that is, a very small value (for example, a negative value). With such a setting, on the contrary, the driver will be careful not to cause such a situation, and as a result, the overspeed will not exceed the above set speed, and safe driving will not occur. Can be encouraged.

(Modified example with a control function that deteriorates the relationship (intimacy))
In the above-described embodiment and each modification, the value of the correction coefficient is controlled so as to affect the increase in the intimacy that finally indicates the relationship, but in this modification, the relationship is deteriorated. As a function to control the operation, it is equipped with a control function that greatly reduces and deducts the corrected total mileage, which is directly linked to the determination of intimacy. If this worsening control is performed when the set deduction conditions are met, the relationships that have been accumulated up to now will collapse at once, so the user should make an effort to prevent such a situation from occurring. Can be expected.

The degree of penalty may be much larger than the control of the correction coefficient based on the overspeed exceeding the first reference speed, and this deduction condition shall be more serious. Taking the overspeed as an example, it is preferable to exceed the third reference speed, which is even faster than the first reference speed, for example. As the third reference speed, for example, it is preferable that the speed exceeds the speed limit of one-shot suspension by 30 km / h. It can be said that the state of overspeed, which is a one-shot suspension, is a very dangerous driving state that leads to a big accident. In such a driving state, it is very scary to assume that the character also has a personality as compared with the case of a slight overspeed, and it can be predicted that the intimacy and reliability with respect to the user who is the driver will also decrease. Therefore, the total corrected mileage is greatly reduced. The lowering distance is set to an excessive amount, for example, in units of 1000 km. On the contrary, the user must be careful not to cause such a situation, and as a result, the excessive speed exceeding the above set speed is exceeded. Safe driving can be promoted without any problems. Further, as an example of this third reference speed (more than 30 km / h), the same speed as the second reference speed shown in the above-mentioned modified example 3 is shown, but the specific speed may be the same or different. good. Set as appropriate according to the purpose.

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

At this time, a warning is given by voice or the like up to [N-1] times. As a warning, for example, the next time you make the same type of violation, you will be notified that the reliability will decrease, and if you continue to make the same type of violation, the total corrected mileage due to intimacy will be greatly reduced. It is possible to urge the user to slow down by warning instead of suddenly lowering it. If the same violation is made despite the warning, the advice from the character is ignored, and control is performed to reduce the total corrected mileage.

Specifically, the control unit 18 periodically acquires the vehicle speed included in the OBD information of the RAM (for example, 1 second), and determines whether or not the third reference speed is exceeded. If the speed is less than or equal to the third reference speed, this judgment ends. If the speed exceeds the third reference speed, the control unit 18 gives the first warning. After that, it is continuously judged whether the speed exceeds the third reference speed on a regular basis. If the vehicle speed drops below the third reference speed even once 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 will be given again. Further, when the state where the speed exceeds the third reference speed continues for a certain period of time (for example, 3 minutes), the control unit 18 issues a second warning. After that, the control unit 18 periodically acquires the vehicle speed and compares it with the third reference speed. Then, if the vehicle speed falls below the third reference speed even once, it is assumed that the series of overspeed states this time have been resolved. Therefore, if the vehicle speed exceeds the third reference speed after that, the control unit 18 gives the first warning again. On the other hand, if the state in which the third reference speed is exceeded continues for a certain period of time (for example, 3 minutes) even after the second warning, the control unit 18 subtracts the corrected total mileage 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 character's intimacy is greatly reduced because he / she has no intention of observing the speed limit and does not listen to the character's request.

In addition, when the vehicle travels at a speed exceeding the third reference speed for 6 minutes, it is advisable to output the character information (the character is not displayed) so that the character does not get angry. In this way, the driver is lonely because the corrected total mileage is greatly subtracted and the intimacy is lowered, and the character information is not output as if the character had run away from home, so that the driver cannot meet the character. Therefore, the driver will try to drive so as not to satisfy the set conditions. Therefore, if the conditions set as shown in this modification are unfavorable driving such as extremely dangerous driving, the driver is appropriate. It's good because you will be driving a lot.

(Modification example with character information (night drive mode) that is output stochastically)
As described in the embodiment, the character information is output by extracting the corresponding character information from the internal data shown in FIGS. 20 to 24 based on the OBD information, the position information, the map information, and the like acquired by the control unit 18. To do. In this modified example, the character information is provided with something that is output stochastically so that the relationship affects this probability. In this way, the probability that the predetermined character information is output depends on the relationship, which increases the gameplay and is interesting.

The character information that appears with this probability is the night drive mode that is output in the night time zone. That is, as described in the embodiment, "(3) Sleep-talking while sleeping" (FIG. 24) outputs character information for sleeping-talking in a cycle of 5 minutes every 10 to 30 minutes in the night time zone. .. That is, since the character is also a creature and sleeps in the night time zone, even if there is a surrounding target object, the existence of the target object is not notified as in the daytime time zone. In other words, the output content of the character information differs depending on the time zone, the daytime time zone is the normal operation time zone when the character wakes up and makes various notifications, and the night time zone is the main activity of sleeping. There is an unusual (standby) operating time zone that does not (speak).

Then, for example, when the driver mainly runs in the night time zone, the character information indicating the sleeping state is output like a sleep-talk, which 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 be active at night and sleep in the day because the character lacks humanity. Therefore, in this modified example, as the drive mode, the character wakes up by probability and performs a normal operation such as outputting character information in the daytime time zone based on the relationship (intimacy) even in the nighttime time zone. To be equipped. As a result, it works even at night once every few times, which makes the game more interesting. What's more, the sleeping character wakes up for you and performs normal actions during the daytime, such as notifying you of the existence of the target target, so it's good to be impressed.

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

Specifically, 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. The double touch represents a state of tapping "tonton" and "tonton" so as to wake up the sleeping person. The probability of whether or not this night drive mode is activated increases according to the degree of relationship and intimacy. In the above-described embodiment, the intimacy is divided into four stages from 0 to 3, so for example, when the intimacy is 0, the probability is 1/4, and when the intimacy is 1, the probability is 1/2. When the intimacy is 2, the probability is 3/4, and when the intimacy is 3, the probability is 1/1 (100%).

In addition, it may be divided into smaller parts instead of the rough division as in the case of four stages. For example, the level of intimacy for night drive mode is level = corrected total mileage / 10000
(The level increases by 1 every 10km)
Level * 0.25 [%]
With the probability of, the character activates the drive mode in response to the invitation and outputs various character information. In this way, if it exceeds 4000 km, the probability exceeds 100%, so that it always starts.

In addition, the character operating in the night drive mode should wear dressed-up night drive wear.

(Modification example of adjustment of correction coefficient 4: Adjustment according to eco-driving situation)
This modification uses the eco-driving situation as information when adjusting the correction coefficient. Eco-driving is calculated based on, for example, fuel efficiency. Then, when the control unit 18 determines that the vehicle is in eco-driving, the control unit 18 makes a positive assessment and increases the correction coefficient by a predetermined value.

The OBD information includes the current fuel consumption, which is the average fuel consumption from the engine ON, the instantaneous fuel consumption (every 200 ms), and the lifetime fuel consumption, which is the average fuel consumption including the fuel consumption during past driving. Since the information related to these fuel consumptions 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 fuel consumption this time, and the instantaneous fuel consumption is larger (fuel consumption is better). ) In the case of eco-driving, a predetermined increase value (for example, 0.5) is added to the correction coefficient. Then, for example, if the normal correction coefficient is 2, the correction coefficient increases to 2.5 during eco-driving.

Since the fuel consumption this time is the average of the history of the instantaneous fuel consumption from the engine ON, when the instantaneous fuel consumption becomes high, it is reflected in the fuel consumption this time and becomes high, and when the instantaneous fuel consumption becomes low, it is reflected in the fuel consumption this time. Being low. Therefore, it is not possible to continue the eco-state in which the instantaneous fuel consumption is always higher than the fuel consumption this time, and the instantaneous fuel consumption exceeds or falls below the fuel consumption this time alternately. Only a positive assessment was adopted as both conditions occur.

Especially during the period when the foot brake or engine brake is used without pressing the access pedal, such as when the vehicle is stopped, the instantaneous fuel consumption is high, so it is advisable to cause such a condition. Then, the evaluation of the current driving (whether or not the eco-friendly luck is carried out) can be promptly performed.

The driver will actively drive eco-driving in order to get a positive assessment. Eco-driving is preferable because it consumes less fuel and is economical, is environmentally friendly, and has less speed fluctuations, resulting in a comfortable ride.

(Modification example related to 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. Runaway conditions include, for example, rough driving and not listening to the character. Rough driving may be, for example, driving exceeding a predetermined speed (for example, a third reference speed), or a state in which acceleration exceeds a threshold value a plurality of times over a certain period of time. If you do not listen to the character, you may continue driving without following the warning even though you have given a warning.

The return conditions include, for example, standard conditions such as the passage of a certain time or running a certain mileage, and the addition of a predetermined item described later. The elapsed time may be, for example, the operating time of the system or the elapsed time in the real world. When the character information is not output, the user cannot meet the character and becomes lonely. Therefore, the user will try to drive so as not to satisfy the set conditions. Therefore, if the set conditions are unfavorable driving such as extremely dangerous driving, the user will drive appropriately. good. Even if the character information is not output once, for example, if the standard condition is cleared, the character information is output again, but if the standard condition is not cleared, for example, an item is given. By incorporating a mechanism in which character information is output according to special return conditions, the user will perform an act to get an item, and the game quality will increase. For example, you can get an item by actually moving to a predetermined place, or you can access a predetermined server site and get it for a fee or free of charge.

(Modification example with item get function)
Set the installation point of the item that affects the character's condition on the map, and when the vehicle goes to the location of the installation point, you will get the item with a certain probability. The installation points may be, for example, SA or PA on a highway, view point parking, which is a parking lot in a good landscape, a general roadside station, or a highway oasis. In this case, it is advisable to stop at the parking lot at those installation points as a condition for getting the item.

Since all of them have parking facilities, they may stop by for a break during driving, and it is preferable to use these parking facilities to give the driver a rest. The reason why the parking lot is required to stop is to eliminate the mere passing through SA or the like.

The items you get can be saved and used to affect the character's condition. The state of the character affects the output of the character information, which is good because the game quality is increased.

Items include, for example, items for improving relationships (intimacy) (adding a predetermined distance to the total corrected mileage stored in the RAM, etc.), items for which the correction coefficient does not decrease for a certain period, and items for which the correction coefficient increases for a certain period. , There are items that return the correction coefficient to the normal correction coefficient, items that return from the state where the character disappears from the screen (appears on the screen), items that increase the probability that night mode is activated, and so on.

For example, as an item whose correction coefficient does not decrease, there is, for example, a sickness drink. When you drink a sickness drink, the accelerometer does not respond for a certain period of time (time, mileage, etc.), that is, the correction coefficient is controlled so that it does not decrease even if the acceleration exceeds the threshold value. That is, the control unit 18 adds L without resetting even if the acceleration exceeds the threshold value. By this, even when the curve continues on a mountain road, for example, and the acceleration in the left-right direction easily exceeds the threshold value, the driver can drive without worrying about the acceleration. This anti-sickness drink should be drunk in front of the mountain road, so it is recommended to install it at a roadside station at the foot of the mountain, for example.

Items that return from the state in which the character disappears from the screen (appear on the screen) include, for example, gift items. That is, if the runaway condition such as exceeding the third reference speed three times in a row is satisfied, the character will not appear. In such a case, if a predetermined return condition is satisfied, for example, 24 hours have passed, the character appears on the display unit again, but by giving a present item, the character's mood returns and immediately appears on the display unit and returns.

To get this character, the control unit 18 first reads the vehicle position coordinates stored in the RAM, recognizes the current position, and determines whether or not there is an item installation location in the vicinity from the map information stored in the database 19. .. Then, 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. Then, when the item can be provided, the control unit 18 utters an item get flag phrase and guides the item to that point. The guidance is, for example, information that identifies the place where the item is set (information about the position is notified, the name of the equipment (○○ service area) is notified, only voice is used, or the character is displayed. In some cases, a predetermined animation or the icon of the corresponding equipment displayed on the display unit may be made to stand out.

The condition for the item to be available is that, in addition to the fact that the item can be provided is selected by the above probability, the correction coefficient must be equal to or higher than a certain threshold value (safe driving state). Furthermore, since SA / PA and the like are located on the expressway, if the current traveling position of the vehicle does not identify the expressway, the item get phrase will not be 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 the item is necessary by himself / herself, and if necessary, moves to the target target. Then, you can get items by stopping at the target target (parking lot). The obtained item may be stored in RAM or EEPROM, for example. In addition, since roadside stations are located on ordinary roads, it is relatively easy to stop by many times. Therefore, the number of items that can be obtained at the same location is limited to 1 item per day.

(Other variants)
The amount of reduction in the amount of change when the setting condition is not satisfied may be constant regardless of whether the setting condition is strict or not, or the amount of reduction may be different depending on the difficulty level of the setting condition. In the above-described embodiment and modification, the change due to intimacy is limited to the character voice, but the character image may be changed. Further, the vehicle speed is acquired by using the vehicle speed information included in the OBD information, but the present invention is not limited to this, and the speed may be calculated based on, for example, the history of the position information. Furthermore, it is preferable that the number and frequency of times and frequency that the character outputs voice and talks increase as the intimacy increases. Further, the control for improving the intimacy may be performed based on the traveling speed or the power ON time or the like.

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

In the above-described embodiment and modification, a database 19 that stores various information is provided in the apparatus, and the control unit 18 accesses the database 19 to read necessary information and performs various processes.
