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 speed (VDEB) of a front wheel in relation to the body shell,
- a means (51, 52) for detecting an impact when the travel speed exceeds a determined threshold, a means for determining a corrected lateral acceleration of the vehicle,
- a means for inhibiting the impact detected when the corrected lateral acceleration is greater than or equal to a determined lateral acceleration inhibition threshold in terms of absolute value, and
- a means (53, 54) for calculating a set value (ERP) for the actuator of the shock absorber of the rear wheel located on the same side as the above-mentioned front wheel when an impact is detected.
