Abstract: To distribute the braking force to both the left and right wheels of a vehicle is one of the most important factors for braking stability when the vehicle is braking on turning. A new method to control dynamically the braking force distribution on turning a vehicle is proposed on the principle of forward-feed control of steering angle, with the intention of meeting the demand of braking stability on turning a vehicle under any road condition. A 3-wheel vehicle model of 2 degrees of freedom is thus established for a simulation of braking force distribution, of which the results show that this method greatly reduces the difference between the actual and ideal lateral wobble frequencies in the process from the very beginning of braking operation to its end. The steerability and effectiveness of the method are therefore verified.
