Abstract
A steer-by-wire vehicle includes a steering actuator configured to turn a wheel and a reaction actuator configure to apply a torque to a steering wheel. An electronic control unit of a control apparatus for the vehicle is configured to execute normal steering control for turning the wheel and applying a reaction torque to the steering wheel according to a rotation of the steering wheel, and, when an activation condition including that the normal steering control is not needed is satisfied, execute rotation suppression control for suppressing the rotation of the steeling wheel without prohibiting the rotation of the steering wheel. Specifically, the electronic control unit is configured to, based on a steering speed or a steering torque, determine a rotation suppression torque for suppressing the rotation of the steering wheel, and control the reaction actuator such that the rotation suppression torque is applied to the steering wheel.
