Dynamic Control of Braking-Force Distribution as Turning Braking

Abstract

The Braking-force distribution on the left and right wheels is a key factor influencing the braking performance of vehicles at a corner. To promote the braking stability and the control ability at the turning-braking process, a new method based on the steering-angle feedforward control principle was proposed to realize dynamic braking-force distribution on the left and right wheels. A vehicle model of three wheels with two freedom degrees was established. Computer simulation of the turning-braking process with dynamic distribution control was carried out. The simulated results show that the difference between the actual yaw rate and the ideal one is significantly reduced at the period of braking being effective. It is validated that the method can effectively improve the braking stability and the control ability of vehicles at the turning-braking process.
