  • Patent number: 8190327
    Abstract: The invention relates to a device for controlling the suspension of the body shell of a motor vehicle. The inventive device comprises a calculator (CSS) which can calculate a control value (ER) for an actuator (M) of a shock absorber (AM) of the suspension (S) as a function of at least one modal body shell speed calculated from a modal body shell acceleration. The invention is characterized by a sensor (CAP-DEB) for sensing wheel (A,B, C, D) travel in relation to the body shell, which is connected to a first means (CAL) for calculating the modal body shell acceleration from the travel measurement (DEB) provided by the sensor (CAP-DEB).

  • Patent number: 8060277
    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 sensor for sensing wheel travel in relation to the body shell for each wheel, a first means (20, 21) for calculating a variable modal shock absorption gain bmod as a function of at least the travel measurements in order to calculate a first set modal shock absorption stress Fmod using formula: Fmod=?bmod·Vmod and a second means (22) for calculating the set force of the shock absorber as a function of the first stress Fmod.

  • Patent number: 8005591
    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.

  • Patent number: 7949445
    Abstract: A device for controlling the suspension of the body shell of a motor vehicle performs calculation of a relative modal body shell speed in relation to the mid-plane of the wheels, and calculation of the set modal stress of the damper as a function of the relative modal body shell speed in relation to the mid-plane of the wheels. The control value includes a determined shock absorption principle from among a plurality of different shock absorption principles that impose the force of the damper as a function of its travel speed.
