VEHICULAR STEERING CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a vehicular steering control device capable of controlling a vehicle without a sense of incompatibility as aim of a driver up to a high speed from a low speed. SOLUTION: In this vehicular steering control device for controlling a turning angle of a steered wheel of the vehicle according to a steering angle of a steering wheel, a steering ratio changing means for changing the ratio of the turning angle to the steering angle is formed as a means for changing the ratio so that a variation in a yaw rate generated in the vehicle to a variation in the steering angle becomes constant when a speed of the vehicle is less than a preset vehicle speed, and changing the ratio so that a variation in lateral acceleration generated in the vehicle to a variation in the steering angle becomes constant when the speed of the vehicle is the preset vehicle speed or more.
