CONTROL DEVICE AND CONTROL METHOD FOR VEHICLE

摘要

In control of a vehicle that is provided with a steering torque supply device that supplies a steering torque to a steering device coupled to a steered wheel and a steering transmission ratio variation device that changes a steering transmission ratio, the control includes: setting a target state quantity for keeping the vehicle (10) in a target lane; controlling the steering transmission ratio variation device (200, 600) so that a state quantity of the vehicle (10) becomes the set target state quantity;* controlling the steering torque supply device (400) so that a steering reaction restriction torque that restricts a steering reaction torque generated in the steering device is supplied with the steering device as the steering torque when the vehicle is kept within the target lane; and correcting the steering reaction restriction torque on the basis of a steering input when the steering input from a driver of the vehicle (10) is produced.
