Abstract
In a front and rear wheel steering device for a vehicle in which the steering angle ratio of the rear wheels relative to the front wheels is variable according to the vehicle speed, by accounting for the magnitude of vehicle acceleration in determining the steering angle ratio of the rear wheels by using a mathematical function in the form of f(u) - g(u')where u is a vehicle speed and u' is a change rate of the vehicle speed, it is possible to reduce the slip angle of the vehicle to zero irrespective of the vehicle speed and the vehicle acceleration and the phase delay of the lateral response of the vehicle can be reduced, whereby the driveability of the vehicle is substantially improved and, thus, driving a car can be made easier, safer and less tiring.
