Abstract:
1. Suspension control device for a motor vehicle body on its wheels (A), having a computer (CSS) adapted to calculate a control magnitude (ER) for an actuator (M) of at least one variable damper (AM) of the suspension, wherein the device has a means for measuring the displacement (DEB) and the displacement speed (VDEB), with respect to the body, of the right wheel and the left wheel located on a same front and/or rear axle, a means for measuring the vehicle speed (VVH), and a means for modifying the detection thresholds as a function of the measured speed (VVH) of the vehicle, and wherein the computer has a means for detecting a large wheel movement amplitude, when each of the left wheel displacement (DEB(A)) and the right wheel displacement (DEB(B)) exceeds a first prescribed detection threshold and when each of the left wheel displacement speed (VDEB(A)) and the right wheel displacement speed (VDEB(B)) exceeds a second prescribed detection threshold, a means for calculating a setpoint magnitude (ERGD) for the actuator of the damper of the wheels, when a large wheel movement amplitude is detected, a means for calculating said control magnitude (ER) as a function of at least said setpoint magnitude (ERGD).
