ABSTRACT:
The invention proposes a method for regulating a stability control system of a vehicle based on the forces acting at the center of each wheel of the vehicle. The actions of the driver, i.e. steering, acceleration or braking, produce forces (changes in forces) are transmitted by the tires to the ground. Control of the operating means of the vehicle (active anti-roll device, engine torque, braking torque, load per wheel or direction) utilizes instructions resulting from the actions of the driver to apply forces. The invention proposes a method of expressing, in terms of forces, the inputs of the driver as a function of the inertia of the vehicle body, velocity of forward movement of the vehicle, and angle at the steering wheel (steering wheel velocity and steering wheel acceleration). If the actual forces that are measured do not correspond to the forces desired by the driver, the active system compensates for this difference by acting on the force distributions in the chassis.
