Four-wheel steering device for an automotive vehicle

Abstract

Abstract A four-wheel steering device for an automotive vehicle, which comprises means inducing steering corrections on each axle as a function of the instantaneous velocity S' of the vehicle, of its angular yaw velocity theta ' and of its lateral acceleration R. Calculation means (8) elaborate the correction signals in a closed loop so as to achieve simultaneously the two following conditions: - maintaining the attitude angle close to zero at each instant and not only in the stationary state; - obtaining, at any instantaneous velocity S' of the vehicle and at any steering lock angle delta v of the steering wheel, a single lateral acceleration R given in advance and also independent of whether the vehicle is stationary or not at each instant. <IMAGE>
