On the other hand, when the driver who is driving the vehicle 110 acquires the driving history information that "the driver will decelerate when approaching a pedestrian" and the surrounding environment information that a pedestrian exists in the vicinity of the vehicle 110, the situation determination unit 151 determines whether the vehicle 110 can be determined not to pose a danger to pedestrians.

Furthermore, the situation determination unit 151 can also make a situation determination based on the operation input information supplied from the operation input acquisition unit 160 in addition to the driving history information and the surrounding environment information. For example, the driving history information that the driver who is driving the vehicle 110 "is the first time to drive near the current location", the surrounding environment information that there is a road sign prohibiting right turn, and the operation input information indicating the operation of the right blinker. , the situation determination unit 151 can determine that the vehicle 110 may violate the traffic rule prohibiting right turns. Further, for example, driving history information that the driver who is driving the vehicle 110 "is the first time to drive in the vicinity of the current location", surrounding environment information that there is a road sign prohibiting right turn, and rudder of the steering wheel to the right. When the operation input information indicating the corner is acquired, the situation determination unit 151 can determine that the vehicle 110 has violated the traffic rule prohibiting a right turn.

Furthermore, the situation determination unit 151 can also make a situation determination based on the vehicle motion information supplied from the vehicle motion acquisition unit 161 in addition to the driving history information and the surrounding environment information. For example, driving history information that the driver who is driving the vehicle 110 has made a stop violation multiple times, surrounding environment information that there is a stop road sign, and vehicle motion that the vehicle 110 is not decelerating. Upon acquiring the information, the situation determination unit 151 can determine that the vehicle 110 may violate the traffic rule of temporary stop. In addition, the driving history information that the driver who is driving the vehicle 110 does not decelerate even when approaching a pedestrian, the surrounding environment information that there is a pedestrian in the vicinity of the vehicle 110, and the vehicle 110 not decelerating. Upon acquiring the vehicle motion information, the situation determination unit 151 can determine that the vehicle 110 is dangerous to pedestrians.

A situation determination can be made based on at least one of the map information. For example, the situation judgment unit 151 can grasp traffic rules such as one-way streets based on the map information and use them for situation judgment. In addition, the situation judgment unit 151 can use the type and frequency of traffic violations and the frequency of accidents around the current position for situation judgment based on the position information. Furthermore, the situation judgment unit 151 can use the presence or absence of pedestrians and bicycles in the vicinity of the infrastructure and the content of traffic signs for situation judgment based on external information. can be supplemented based on external information.

In addition, the situation determination unit 151 obtains at least one of vehicle information, accident/violation information, and pedestrian/bicycle information of the other vehicle 110 from the database 130 (see FIG. 3), and obtains the information obtained from the database. It is also possible to judge the situation based on the driving history information and the surrounding environment information. By using the vehicle information acquired from the database 130 for situation judgment, the situation judgment unit 151 can judge the situation by using the situation of other vehicles such as the current position and speed. In addition, the situation judgment unit 151 can use the accident/violation information and the pedestrian/bicycle information acquired from the database 130 for situation judgment to supplement the surrounding environment information and external information.
