  The identification information of the own vehicle stored in advance in the internal information acquisition unit 11 is, for example, information such as the number of the own vehicle (for example, vehicle registration number or vehicle number), vehicle type and identification number set for each vehicle. The driver information stored in advance in the internal information acquisition unit 11 is, for example, a characteristic of the driver of the own vehicle.

  The communication I / F 14 is an interface circuit or module for enabling communication connection between the guide device 100 and an external device such as a server via a network. The communication I / F 14 performs communication according to standards such as IEEE802.3, IEEE802.11 or Wi-Fi, LTE, 3G, 4G, 5G.

  The control unit 20 is a processing device that performs various calculations and controls the overall operation of the guide device 100. The control unit 20 includes a general-purpose processor such as a CPU or MPU that realizes a predetermined function by executing a program stored in the storage unit 30. The control unit 20 is composed of, for example, an ECU (Electronic Control Unit). The control unit 20 is not limited to one that realizes a predetermined function through the cooperation of hardware and software, and is a hardware circuit such as an FPGA, ASIC, or DSP designed as a dedicated circuit for realizing the predetermined function. It may be configured.

  The control unit 20 includes an internal information analysis unit 21, a determination unit 23, and a guidance information generation unit 24 as software modules realized by executing a program.

  The internal information analysis unit 21 receives the internal information from the internal information acquisition unit 11, analyzes the internal information, and outputs the analysis result. For example, the internal information analysis unit 21 generates, as the analysis result, information indicating the identification information of the own vehicle, the running state of the own vehicle, the psychological state of the driver of the own vehicle, and the like. The generated information may be stored in the storage unit 30. The internal information analysis unit 21 outputs the generated information to the outside via the communication I / F 14.

  The determination unit 23 receives the information of the own vehicle and the other vehicle stored in the server 50, and outputs the information of the other vehicle that should avoid the encounter. The determination unit 23 determines another vehicle that should avoid an encounter, based on the inter-vehicle influence information 32 stored in advance in the storage unit 30. The determination unit 23 stores the determination result in the determination result database 33 of the storage unit 30.

  The guidance information generation unit 24 generates guidance information for guiding the driver about a travel route or the like on which the vehicle should travel, based on the determination result database 33 of the storage unit 30 and the route information 31. The route information 31 includes, for example, map information and information indicating a candidate for a travel route to a destination set by the user.

Further, the server 50 transmits the stored information to the guide device 100 of the automobiles 2a to 2d in response to the request signal from the guide device 100 of the automobiles 2a to 2d.

[2. motion]
FIG. 3 is a flowchart showing an operation flow of the guide device 100 according to the first embodiment. First, the control unit 20 of the guide device 100 controls the internal information acquisition unit 11 to acquire internal information (S11). The internal information is, for example, information indicating the position, speed, acceleration, angular velocity and inclination of the own vehicle, the behavior of the driver of the own vehicle, a biological signal, and the like.

  Next, the control unit 20 as the internal information analysis unit 21 analyzes the acquired internal information and generates information indicating the position of the own vehicle, the running state, the psychological state of the driver, and the like (S12). The traveling state of the host vehicle includes, for example, states such as “rough”, “lost”, and “loose”. For example, the control unit 20 acquires the acceleration of the own vehicle measured by the acceleration sensor, and a state in which the magnitude of the acceleration is equal to or greater than a preset threshold value is preset within a preset preset time. When the number of occurrences is equal to or more than the threshold value, an analysis result of "rough" is generated for the running state of the vehicle.

  In addition, for example, the control unit 20 acquires the yaw angular acceleration of the host vehicle measured by the gyro sensor, and a state in which the magnitude of the yaw angular acceleration is equal to or greater than a preset threshold value is set for a preset time. If the number of occurrences exceeds a preset threshold value, the analysis result that the vehicle is running is "staggered" is generated.

  Further, for example, the control unit 20 acquires the speed of the own vehicle measured by the speedometer, and the state in which the speed of the own vehicle is less than the preset threshold value is preset within a preset preset time. When the number of times of occurrence is equal to or more than the set threshold value, the analysis result that the running state of the own vehicle is “loose” is generated. The threshold for speed may be changed over time, or may be the legal speed of the road on which the vehicle is currently traveling. Alternatively, the speed threshold may be set to the current average speed of other vehicles around the vehicle.

  The driver's psychological state includes, for example, states such as “frustrated”, “tensioned”, “distracted”, and “frustrated”. For example, the control unit 20 acquires the image of the driver captured by the in-vehicle camera and analyzes the image. By the image analysis, the state in which the amount of movement change of the driver's head, arms, legs, and the like is equal to or greater than a threshold value, within a predetermined time period set in advance, occurs a number of times equal to or greater than a preset threshold value, The control unit 20 generates an analysis result indicating that the driver's psychological state is "frustrated."

  Further, for example, the control unit 20 acquires the pulse rate of the driver measured by the pulse sensor or the pulse wave sensor, and the state in which the pulse rate is equal to or higher than the threshold value occurs for a predetermined time or longer that is set in advance. In this case, an analysis result that the driver's psychological state is “tensed” is generated. Alternatively, the control unit 20 may generate an analysis result that the driver is “tensed” when the sweat rate of the driver is equal to or more than a threshold value, based on the detection result of the sweat rate by the sweat sensor.

  Further, for example, the control unit 20 acquires the driver's weight movement amount measured by the pressure sensor provided in the seat, and the state in which the weight movement amount is equal to or more than the threshold value is within a predetermined time set in advance. If the number of occurrences is equal to or greater than a preset threshold value, an analysis result that the driver's psychological state is “distracted” is generated.

  In addition, for example, the control unit 20, the speed measured by a speedometer, an acceleration sensor, an engine speed sensor, etc., acceleration, a state in which the engine speed or the like is equal to or more than a threshold value within a preset predetermined time, When the number of occurrences is equal to or greater than a preset threshold value, an analysis result that the driver's psychological state is “in a hurry” is generated. The threshold relating to the speed may be temporally changed based on the legal speed of the road on which the vehicle is currently traveling.

  Next, the control unit 20 stores the analysis result generated in step S12 in the server 50 via the communication I / F 14 (S13). In addition to the own vehicle, other vehicles similarly store internal information for the other vehicles in the server 50. In this way, from a number of automobiles, information about the automobiles is stored in the server 50 and a database of automobile information is constructed.

  FIG. 4 is a diagram exemplifying a database of automobile information stored in the server 50. The information indicating the identification number, the number, the vehicle type, and the driver's character shown in FIG. 4 is acquired by the internal information acquisition unit 11 or stored in the storage unit 30 in advance, and stored in the server 50 via the communication I / F 14. To be done. Alternatively, the identification number, the number, the vehicle type, and the personality of the driver may be registered in the server 50 in advance. Here, the identification number is, for example, a unique number given to each automobile. The identification number is given, for example, when manufacturing an automobile.

  When there are a plurality of drivers who can drive the vehicle, information indicating the personality of each driver may be stored in the server 50. Further, the control unit 20 may specify the driver who is currently driving the own vehicle by, for example, the internal information acquisition unit 11, and store the current driver in the server 50. As a result, the current personality of the driver is specified.

  The information indicating the current location shown in FIG. 4 is generated by the internal information analysis unit 21 based on the information acquired by the internal information acquisition unit 11 such as GPS. The information indicating the characteristics of the current location shown in FIG. 4 is generated in the server 50 based on, for example, the information indicating the current location and the map information and the road information stored in advance in the server 50. The running state and the psychological state of the driver shown in FIG. 4 are generated by the internal information analysis unit 21, for example.

  The information in the database of the server 50 is constantly updated with new information, for example. For example, the traveling state information of the A vehicle 2a of the server 50 is periodically transmitted from the A vehicle 2a itself to the server 50 and updated at any time.

  Next, the control unit 20 (see FIG. 2) as the determination unit 23 is based on the information on the own vehicle and other vehicles stored in the server 50 and the inter-vehicle influence information 32 stored in the storage unit 30 in advance. Then, the other vehicle that should avoid the encounter is determined (S17).

  FIG. 5 is a diagram showing an example of the inter-vehicle influence information 32. The vehicle-to-vehicle impact information 32 typifies the magnitude of psychological stress given to the driver of the other vehicle by the driver of one vehicle based on the type including the characteristics and states of the two vehicles and their drivers. This is information to guide. The control unit 20 as the determination unit 23 receives the internal information and the external information and determines the degree of the psychological stress exerted by the own vehicle and the other vehicle on each other, and the inter-vehicle influence information 32 makes this determination. It provides an index for

  In the example shown in FIG. 5, a vehicle classified into a certain type (hereinafter referred to as “stressed vehicle”) encounters a vehicle classified into another type (hereinafter referred to as a “stressed vehicle”). In this case, it indicates whether or not the stressed vehicle receives psychological stress from the stressed vehicle and, if stressed, the magnitude of the stress. The vehicle-to-vehicle influence information 32 is created based on an empirical rule or an experiment.

  The table of FIG. 5 shows, for example, that a car of type 1 driven by a driver who has an impatient personality and is in a calm psychological state on a highway has a mild personality and is a light vehicle. When the vehicle of type I, which is present and the traveling state is slow, is encountered, it shows that the vehicle of type 1 is apt to be slightly stressed by the type I light vehicle. According to this information, a driver of a type 1 car has a calm psychological state, but since he has an impatient personality, he tends to be slightly psychologically stressed by a type I car that is running fast on an expressway. It is based on the rule of thumb.

  In addition, the table of FIG. 5 shows that a vehicle of type 2 driven by a driver having a rough character and a mental state of impatience is considerably susceptible to stress from a vehicle of type I on a road with many traffic lights. Is shown. This information shows that the driver of a type 2 car has a rough personality, but is in a hurried state of impatience, and therefore tends to receive considerable psychological stress from a type I car. It is based on the rule of thumb.

  Further, the table of FIG. 5 shows that the type 2 car is a driver with a cool personality, the car type is a sports car, and the running condition is rough, so that the type 2 car is less susceptible to stress. Shows. This information indicates that the driver of the type 2 car has a rough personality, and has a temperament that does not care about the roughness of driving of another car, for example. Since the vehicle is in a state, it is based on the empirical rule that psychological stress tends to be less likely to occur from a type II car that is not sluggish as long as the vehicle can smoothly proceed.

  In the table of FIG. 5, for convenience of explanation, the stress-susceptibility of a stressed vehicle is described as “hard to be stressed”, “slightly stressed”, and “quite easily stressed”. A vehicle's susceptibility to stress may be represented numerically. For example, 0 is stored when the stress is not easily received, 1 is stored when the stress is slightly susceptible, and 2 is stored when the stress is easily received. Alternatively, the susceptibility of the stressed vehicle to stress may be classified into two levels of 0 and 1.

  FIG. 6 is a flowchart showing the detailed flow of the determination step S17 shown in FIG. In step S17, for example, the susceptibility (compatibility) of stress between the host vehicle and all the other automobiles is determined, and another vehicle that should avoid encounter is determined. Therefore, first, it is determined whether or not the own vehicle should avoid encountering the vehicle with the identification number 1, and then whether or not it should be avoided that the vehicle with the identification number 2 is avoided. Repeat while changing the identification number.

  That is, first, the control unit 20 as the determination unit 23 sets the identification number i to 1 (S170). Next, the control unit 20 determines whether or not the vehicle with the identification number i is the own vehicle (S171). When the vehicle with the identification number i is the own vehicle (Yes in S171), the control unit 20 increments the identification number i and determines the necessity of avoidance between the vehicle with the next identification number and the own vehicle (S179). ). This is because it is not necessary to determine the necessity of avoidance between the own vehicle and the own vehicle.

  When the vehicle with the identification number i is not the own vehicle (No in S171), the control unit 20 sets the vehicle with the identification number i as the stressed vehicle and the vehicle with the identification number i as the stressed vehicle to the inter-vehicle influence information 32 (FIG. 5). The degree of stress received by the vehicle with the identification number i (stressed vehicle) is extracted (S172).

  Next, the control unit 20 determines whether or not the degree of stress received by the vehicle with the identification number i exceeds a preset threshold T (S173). The threshold value T is stored in advance in the storage unit 30, for example.

  When it is determined that the degree of stress on the vehicle with the identification number i exceeds the threshold T (Yes in S173), the control unit 20 needs to avoid the vehicle from encountering the vehicle with the identification number i. The determination is made (S177). The control unit 20 stores the determination result of step S177 in the determination result database 33 of the storage unit 30.

  When the degree of stress received by the vehicle with the identification number i does not exceed the threshold value T (No in S173), the control unit 20 sets the vehicle with the identification number i as the stressed vehicle and the own vehicle as the stressed vehicle to influence the vehicle-to-vehicle distance. This is applied to the information 32 (FIG. 5) to extract the degree of stress on the vehicle (stressed vehicle) (S174).

  Next, the control unit 20 determines whether or not the stressed degree extracted in step S174 exceeds the threshold value T (S175). In the above example, the thresholds used in step S173 and step S175 are the same threshold value T, but the threshold values used in both steps need not be the same value.

  When it is determined that the degree of stress received by the host vehicle exceeds the threshold T (Yes in S175), the control unit 20 determines that the host vehicle needs to avoid encountering the vehicle with the identification number i ( S177).

  When it is determined in step S175 that the degree of stress received by the host vehicle does not exceed the threshold value T, the control unit 20 determines that it is not necessary to prevent the host vehicle from encountering the vehicle with the identification number i ( S176). The control unit 20 stores the determination result of step S176 in the determination result database 33 of the storage unit 30.

  After the determinations of step S176 and step S177, the control unit 20 determines whether or not the avoidance necessity determination between the own vehicle and all other vehicles is completed (S178). When it is determined that the avoidance necessity determination between the own vehicle and all the other vehicles is completed (Yes in S178), the control unit 20 ends the determination step S17 illustrated in FIG. 6 and illustrated in FIG. It proceeds to step S18. When determining that the avoidance necessity determination between the own vehicle and all other vehicles is not completed (No in S178), the control unit 20 increments the identification number i (S179), and returns to step S171. , The necessity of avoidance between the vehicle having the next identification number and the own vehicle is determined.

  FIG. 7 is a diagram showing an example of the determination result database 33 after the determination step S17 shown in FIG. 6 is completed. As illustrated in FIG. 6, the determination result database 33 stores an identification number of another vehicle and information regarding whether or not it is necessary for the vehicle to avoid encountering the other vehicle.

  In the above example, the example in which it is determined whether or not the avoidance necessity determination between the own vehicle and all the other vehicles is completed in step S178 has been described. However, the operation of the guide device 100 according to the present invention is not limited to this. For example, the own vehicle and another vehicle far away from the own vehicle are unlikely to encounter each other, and therefore it can be considered that it is not necessary to perform the avoidance necessity determination. In the case of thinking in this way, for example, between steps S171 and S172 of FIG. 6, it is determined whether or not the vehicle with the identification number i is within a predetermined distance (for example, 5 km) from the vehicle, and it is determined that there is. The operation of advancing to step S172 and advancing to step S179 may be inserted if it is determined that there is no such operation.

  Returning to FIG. 3, after the determination step S17, the control unit 20 as the guidance information generation unit 24 determines the travel route and the like that the vehicle should follow based on the determination result database 33 and the route information 31 in the storage unit 30. Guide information for guiding the driver is generated (S18). The route information 31 includes a route (route) to the destination derived by the control unit 20 using the map information based on the destination of the vehicle set by the user. The control unit 20 derives a plurality of route candidates to the destination. The control unit 20 serving as the guidance information generation unit 24 selects the route having the lowest possibility of encountering another vehicle that is required to be avoided in the determination result database 33 among the route candidates to the destination, and the route having the first priority. Set to. The control unit 20 may set the second or lower priority order to other candidates of the route to the destination depending on the possibility of encountering another vehicle that is required to be avoided in the determination result database 33.

  Next, the control unit 20 controls the guide unit 40 to notify the user such as the driver of the own vehicle and the fellow passenger based on the generated guide information (S19). For example, the control unit 20 uses the display unit 41 of the guide unit 40 to notify the driver of the route having the first priority by displaying the image. Alternatively, the control unit 20 may use a speaker 42 of the guide unit 40 to notify the driver of the route having the first priority by voice.

  As described above, the control unit 20 guides the driver to take a break at a rest area such as a service area, instead of guiding the route that is unlikely to encounter another vehicle that is required to be avoided in the determination result database 33. You may. The guidance for prompting a break is effective when there are many other vehicles that need to be avoided on the planned traveling route of the vehicle and it is difficult to avoid.

Compared with the flowchart of the first embodiment shown in FIG. 3, the operation of the guide device 200 is as follows: Step S14 of acquiring external information, Step S15 of analyzing the acquired external information, and storing the analysis result in the server 50. The method further includes step S16. Hereinafter, these operations will be described.

  The control unit 20 controls the external information acquisition unit 12 to acquire external information indicating the states of the other vehicle and the driver of the other vehicle (S14). For example, the control unit 20 acquires a distance image regarding another vehicle by using a distance sensor such as a vehicle exterior camera or a radar.

  Next, the control unit 20 as the external information analysis unit 22 analyzes the acquired external information and generates an analysis result indicating the position, running state, etc. of another vehicle (S15). FIG. 10 is a diagram showing an example of information about other peripheral vehicles generated by the control unit 20 as the external information analysis unit 22.

  For example, the control unit 20 can obtain the information of the number written on the license plate of the other vehicle by analyzing the image of the other vehicle acquired by the camera outside the vehicle.

  For example, the control unit 20 obtains the distance between the own vehicle and the other vehicle by analyzing the distance image of the other vehicle acquired by the vehicle exterior camera or the distance sensor. As a result, as shown in FIG. 10, the relative position of the other vehicle with respect to the own vehicle is obtained. The control unit 20 as the determination unit 23 may take the relative position into consideration when determining the degree of psychological stress that the own vehicle and the other vehicle exert on each other. For example, each type of the inter-vehicle influence information 32 includes a relative position, and is adjacent to the own vehicle (for example, the relative position is (4 m, 0 m)), in front (for example, the relative position is (0 m, 10 m)), or behind (for example, the relative position). If there is another vehicle at (0 m, −10 m)), the inter-vehicle influence information 32 may include an index that psychological stress is more likely to occur than in the case where there is no other vehicle. Alternatively, when the distance between the own vehicle and another vehicle exceeds a predetermined threshold, the control unit 20 as the determination unit 23 does not determine the degree of psychological stress, or “ You may judge that "you are not subject to psychological stress."

  In addition, the control unit 20 can calculate the speed, acceleration, angular velocity, and inclination of the other vehicle by analyzing the distance image of the other vehicle obtained in time series. As shown in FIG. 10, the control unit 20 can generate information indicating the traveling state of another vehicle by using these pieces of information in the same manner as in the case of analyzing the internal information.

  Returning to FIG. 9, the control unit 20 stores the analysis result generated in step S15 in the server 50 via the communication I / F 14 (S16).

  Due to its nature, steps S12 and S13 shown in FIG. 9 need to be performed after step S11. In addition, the above steps S15 and S16 need to be performed after step S14 due to its nature. However, step S11 and step S14 are in no particular order, and unlike FIG. 9, step S11 may be performed after step S14.

  As described above, in addition to the configuration of the guide device 100 according to the first embodiment, the guide device 200 according to the second embodiment further includes the external information acquisition unit 12 that acquires information about other vehicles around the own vehicle. Prepare As a result, the information about each vehicle stored in the server 50 is made up of data measured by other surrounding vehicles in addition to the internal information about the vehicle obtained by each vehicle. Therefore, the guide device 200 can improve the accuracy of the information of each vehicle stored in the server 50. As a result, the guide device 200 applies the information of the own vehicle and the information of the other vehicle to the inter-vehicle influence information 32, and more accurately determines the magnitude of the psychological stress that the own vehicle and the other vehicle receive from each other. be able to.
