METHOD FOR ESTIMATING IN REAL TIME A FRONT EFFORT AND A REAR EFFORT APPLIED BY THE GROUND TO A VEHICLE

摘要

The invention concerns a method for estimating in real time, in a motor vehicle, a front force (F_yV) and a rear force (F_yR), these forces being applied by the ground to the front wheels and to the rear wheels, respectively, of the vehicle along a transverse direction. The method consists in: equipping this vehicle with a measuring device supplying a signal representative of a measured transverse acceleration (γ_T) and a signal representative of a measured yaw rate (γ_T), and with a processing unit; applying to these signals a processing operation to determine a front force and a rear force based on a dynamic model of the vehicle such as a model of the bicycle type. The invention applies to the field of active safety.
