FRONT WHEEL STEERING CONTROL DEVICE

摘要

A front wheel steering control device that is based on a theory of driving stability for a vehicle and improves driving stability of a vehicle relative to a steering angle. A front wheel steering control device for improving driving stability of a vehicle (100) has reading means for reading a steering angle and a vehicle speed of the vehicle, first calculation means for calculating, based on the steering angle and the vehicle speed read by the reading means, a yaw rate of the vehicle with a side-skid angle of the vehicle's center of gravity always set at 0, second calculation means for calculating a target actual steering angle of front wheels for realizing the yaw rate calculated by the first calculation means, and control means for controlling the steering of the vehicle based on the target actual steering angle of front wheels calculated by the second calculation means. The steering gear ratio and derivative steering gain of an ideal vehicle can be set relatively simply and theoretically clearly.
