Abstract
A vehicle of a steer-by-wire type includes: a turning device that turns a wheel by actuating a turning motor; and a reaction torque generation device that applies a reaction torque to a steering wheel by actuating a reaction motor. A control device for the vehicle is configured to control turning of the wheel by controlling the turning motor and to control the reaction torque by controlling the reaction motor, according to rotation of the steering wheel. When a power output limiting condition is satisfied, the control device executes not only power output limiting processing that limits a power output of the turning motor but also reaction torque increasing processing. In the reaction torque increasing processing, the control device controls the reaction torque to make the steering wheel harder to rotate as compared with a case where the power output limiting processing is not executed.
