Suspension device having a trim corrector
First Claim
1. A vehicle suspension device having at least two suspension systems, each connecting a non-suspended mass comprising a wheel to a suspended mass, with possible vertical deflection, each suspension system comprising a vertical suspension reacting to the variations of distance between the suspended mass and the non-suspended mass, the said vertical suspension comprising a spring and a reversible electric actuator acting in parallel with the spring, the device comprising means for controlling a trim correction, the device comprising means for controlling the electric actuators of each of the said suspension systems so that they each develop a force made up of the addition of two components:
- a damping component opposing the deflection speed and a trim correction component, the said trim correction components applying a trim correction to the suspended mass.

Abstract
A vehicle suspension device having, for each suspension system, a suspension including a spring and a reversible electric actuator acting in parallel with the spring. The device includes provision for controlling the electric actuators of each of the suspension systems so that they each develop a force having two components: a damping component opposing the deflection speed and a trim correction component, the said trim correction components applying a trim correction torque to the suspended mass.
