VEHICLE CONTROLLER AND VEHICLE CONTROL SYSTEM

A vehicle controller includes a processor that switches, when detecting a physical abnormality of an occupant of an own vehicle based on physical information of the occupant, the own vehicle to an emergency mode in which the own vehicle automatically travels to a destination. The processor receives, when the own vehicle is switched to the emergency mode, other vehicle information from another vehicle switched to the emergency mode. The other vehicle information includes information on a physical abnormality of an occupant of the other vehicle. Based on the other vehicle information and own vehicle information including information on the physical abnormality of the occupant of the own vehicle, the processor sets the order of priority to determine which of the own vehicle or the other vehicle is allowed to travel preferentially, and sends, based on the order of priority, a medical aid request to an information processor.
