Study on Electronic Braking Force Distribution Control Strategy of the Tractor-Semitrailer Vehicle

摘要

In this paper, a control strategy is proposed by theoretical analysis and off-line simulation verification, so that braking force of tractorsemitrailer Vehicle will be distributed dynamically and namely. Braking force of each axle will be distributed and controlled indirectly by closed-loop control of vehicle's deceleration. Through this control method, vehicle's deceleration is independent of the load situation, which can improve the driving comfort. In addition, the proportion of braking pressure between axles is according to the proportion of the load of each axle, so as to achieve the ideal braking force distribution. At the same time, the same wheel speed of each axle would be ensured, to avoid the inconsistencies in tire wear.
