Abstract: A control unit configured to control a reaction force actuator that applies steering guide torque to a steering wheel calculates a target steering angle for causing a vehicle to travel along a curve, calculates target steering guide torque based on a deviation between the target steering angle and an actual steering angle, modifies the target steering guide torque such that the target steering guide torque is larger as an index value indicating at least one of the number of times or an integrated time in which a difference between a magnitude of the actual steering angle and a magnitude of the target steering angle exceeds a reference value is larger, and controls the reaction force actuator such that the steering guide torque becomes the target steering guide torque.

Abstract: A control unit that controls a reaction force actuator that applies steering guide torque to a steering wheel: calculates, based on a curvature of a curve of a travel road in front of a vehicle detected by a camera sensor, a target steering angle for causing the vehicle to travel along the curve; calculates a target steering guide torque, based on a deviation between the target steering angle that was calculated a prediction time period earlier and an actual steering angle; adjusts a target steering guide torque such that the target steering guide torque becomes smaller as a probability that a driver performs steering operation to deviate from a lane becomes higher; and controls the reaction force actuator such that the steering guide torque becomes the target steering guide torque.
