Vehicle steering guide torque control apparatus

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.
