DEVICE AND METHOD FOR ESTIMATING THE TOTAL MASS OF A MOTOR VEHICLE WITH ONBOARD CALIBRATION OF SUSPENSION DISPLACEMENT SENSORS

摘要

The device for estimating the total mass of a motor vehicle comprises a first module (2) for estimating the total mass (Malgo) of the motor vehicle on the basis of the dynamic parameters of the vehicle and a second module (3) for estimating the total mass (Mdeb) of the vehicle on the basis of displacement values of each of the suspensions of the vehicle, measured by displacement sensors (6). The estimation device comprises a system (8) for re-calibrating the displacement sensors, fitted onboard the motor vehicle.
