Abstract: A route information storage function having decreased data storage requirements is provided in a vehicle controller that includes a processor, a first storage unit, and a second storage unit and that stores route information indicating a route to a target point. The vehicle controller includes a traveling state acquiring unit that acquires route information on a vehicle, a short-term storage information processing unit that stores the route information in the first storage unit, as short-term storage information, the route information being acquired by the traveling state acquiring unit while the vehicle is traveling, and a long-term storage information processing unit that after the vehicle has reached the target point, determines long-term storage information from short-term storage information stored in the first storage unit, the long-term storage information processing unit storing the determined long-term storage information in the second storage unit.

Abstract: Provided is a vehicle control system which prevents a host vehicle from being controlled by executing a driving support function based on an erroneous lighting state in a case where the lighting state of a traffic light is erroneously determined. The vehicle control system includes: a lighting state determination unit 123 which determines a lighting state of a traffic light placed on a road on which a host vehicle travels, and calculates reliability of the determined lighting state of the traffic light, a dynamic object recognition unit 122 which recognizes information regarding a dynamic object existing around the host vehicle (behavior of another vehicle, a pedestrian, or the like), and a lighting state evaluation unit 131 which updates the reliability of the lighting state calculated by the lighting state determination unit 123 based on the information recognized by the dynamic object recognition unit 122 (information regarding the dynamic object existing around the host vehicle).
