Method for controlling the stability of a vehicle based on lateral forces exerted on each wheel

摘要

A method for regulating a system for controlling the stability of a vehicle based on the forces exerted at the center of each wheel of the vehicle. Since, the actions of the driver, whether steering, accelerating or braking, are reflected by forces (variations in forces) transmitted by the tires to the ground, it is proposed to control the operating means of the vehicle (active anti-roll system, engine torque, braking torque or active steering) by force expectations derived from the actions of the driver. Depending on the speed of travel of the vehicle and the angle to the steering wheel (steering wheel velocity and steering wheel acceleration), the method expresses the inputs of the driver in terms of forces. 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 distributions of forces in the vehicle chassis.
