CONTROL DEVICE OF VEHICLE

摘要

PROBLEM TO BE SOLVED: To make a vehicle follow a target lane without deteriorating drivability.

SOLUTION: This control device (100) for the vehicle (10) includes: a steering torque supply means (400) that supplies steering torque to a steering device coupled to a steered wheel (FL, FR); and a steering transmission ratio varying means (200, 600) that changes a steering transmission ratio. The control device further includes: a setting means for setting a target state quantity for making the vehicle follow a target lane; a first control means controlling the steering transmission ratio varying means in such a manner that a state quantity of the vehicle reaches a set target state quantity; a second control means controlling the steering torque supply means in such a manner that steering reaction restriction torque that restricts steering reaction torque generated in the steering device is supplied as the steering torque when the vehicle is made to follow the target lane; and a correcting means correcting the steering reaction restriction torque on the basis of a steering input when the steering input from a driver of the vehicle is produced.
