WHEEL VERTICAL FORCES DISTRIBUTION AS THE SOURCE OF VEHICLE STABILIZATION

Abstract eng:
The paper presents specific approach in terms of finding the dependency between corrective torque, which is acting to a vehicle in yaw direction, and the tire vertical forces redistribution among four corners in a vehicle. The formula for wheel vertical forces evaluation was derived from the system of equations. There is described the relationship between corrective torque and the tire vertical force variations. Derived body control system algorithm offers the ability to control the lateral dynamics of the vehicle. The limitation of the system has been defined. Generally, the limits are given by the static load of the wheels. The efficiency of the control system was observed and expressed numerically by the vehicle movement close to the adhesion limit.
