Abstract
An object of the present invention is to enhance the reliability of an autonomous driving system. The autonomous driving system includes: a higher-level control devicethat outputs a control target value of an actuator group based on an action plan of a vehicle; and a lower-level control devicethat controls the actuator group of the vehicle based on a command from the higher-level control device. The lower-level control deviceholds the control target value of the vehicle provided by the higher-level control deviceover a specific period. When the higher-level control devicedoes not satisfy a desired function, the lower-level control deviceis configured to be controlled based on the held control target value. The action plan is followed by determining and correcting a difference between an actual action value and the control target value of the vehicle.
