Research on force calculation and distribution in vehicle stability control

The friction force and torque between tires and ground effect the motion states of vehicles directly. Controlling the force and torque is one method of stability control of vehicle. The feasible region of combined force and torque determines the limits of the vehicle motion states, and it is important to the stability control system design. The way of distribute the force to fore tires is also important. A real-time estimation method and force dynamic distribute method are researched in this paper and is applicated in vehicle stability control system. The simulation results show that the method can achieve good control effect.
