Abstract

An information processing apparatus mounted on a vehicle includes a controller configured to be capable of performing driving assist control and notification control. In a case where the vehicle receives another-vehicle information including information about a travel state of another vehicle from another vehicle by vehicle-to-vehicle communication, the controller performs the driving assist control based on the another-vehicle information. Furthermore, in a case where the vehicle receives the another-vehicle information not by vehicle-to-vehicle communication but from a server apparatus that performs communication with another vehicle, the controller performs the notification control based on the another-vehicle information without performing the driving assist control based on the another-vehicle information.

The vehicle according to claim 8 , wherein, in a case where the another-vehicle information is received not by vehicle-to-vehicle communication but from the server apparatus, when the another-vehicle information received from the another vehicle by vehicle-to-vehicle communication and the another-vehicle information received by communication with the server apparatus are same in a predetermined period of time before a time point when reception of the another-vehicle information from the another vehicle by vehicle-to-vehicle communication is disabled, the driving assist control is performed based on the another-vehicle information received from the server apparatus.
10 . The vehicle according to claim 8 , wherein, when the another-vehicle information is received by both vehicle-to-vehicle communication and communication with the server apparatus, and pieces of the another-vehicle information received by respective types of communication are same, the driving assist control that is different from when the another-vehicle information is received only by vehicle-to-vehicle communication is performed based on the another-vehicle information.
11 . The vehicle according to claim 8 , wherein the another-vehicle information includes identification information for identifying the another vehicle.
12 . The vehicle according to claim 8 , wherein the another-vehicle information includes, as the information about the travel state of the another vehicle, at least position information of the another vehicle and a velocity of the another vehicle.
13 . The vehicle according to claim 8 , wherein the driving assist control is stop control of causing an own vehicle to stop automatically or deceleration control of causing the own vehicle to decelerate automatically.
14 . The vehicle according to claim 8 , wherein the notification control is control of notifying a driver of an own vehicle of presence of the another vehicle by audio or an image.
15 . A non-transitory storage medium storing a program for causing an information processing apparatus mounted on a vehicle to perform driving assist control or notification control, wherein the program causes, in a case where the vehicle receives another-vehicle information including information about a travel state of another vehicle from the another vehicle by vehicle-to-vehicle communication, the information processing apparatus to perform the driving assist control based on the another-vehicle information, the driving assist control is a travel control for the vehicle that is automatically performed to prevent the vehicle from colliding into the another-vehicle, and causes, in a case where the vehicle receives the another-vehicle information not by vehicle-to-vehicle communication but from a server apparatus that performs communication with the another vehicle, the information processing apparatus to perform the notification control based on the another-vehicle information without causing the information processing apparatus to perform the driving assist control based on the another-vehicle information.
16 . The non-transitory storage medium according to claim 15 , wherein, in a case where the vehicle receives the another-vehicle information not by vehicle-to-vehicle communication but from the server apparatus, when the another-vehicle information received from the another vehicle by vehicle-to-vehicle communication and the another-vehicle information received by communication with the server apparatus are same in a predetermined period of time before a time point when reception of the another-vehicle information from the another vehicle by vehicle-to-vehicle communication is disabled, the program causes the information processing apparatus to perform the driving assist control based on the another-vehicle information received from the server apparatus.
