Abstract
The invention relates to a device for controlling the suspension of the body shell of a motor vehicle. According to the invention, the device comprises: a means for measuring the travel (DEB(A)) and travel speed (VDEB(A)) of the right and left wheels on a front and/or rear axle system in relation to the body shell, a means (61, 62) for detecting a wide range of wheel movement when the travel (DEB(A)) and speed values exceed a threshold, and a means (64) for calculating a set value (ERGD) for the shock absorber actuator when a wide range of wheel movement is detected.
Claims11
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,
- 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).
