Abstract: The installation of hydraulic regenerative braking system will change the original antilock braking system of a semitrailer train combination while improving its energy efficiency. To ensure the safety of the braking system, it is necessary to integrate the regenerative braking system with the original antilock braking system. Based on the braking system that distributes the three-axle braking force in the fixed proportion, a coordinated control strategy of optimal braking energy recovery and antilock braking is proposed herein. Considering the braking force strength, energy storage state, and road adhesion conditions, the mechanical friction and regenerative braking force are distributed among three axles. Simultaneously, the friction braking force is adjusted to control the wheel slip rate. A co-simulation model of AMESim and MATLAB/Simulink is built. The specific condition is simulated on thesimulation platform. The results show that the proposed coordinated control strategy can achieve 13.48% of braking energy recovery efficiency in the middle and low adhesion roads and medium braking force conditions while the slip rate of three-axle is maintained within the optimal range. 

Key words: tractor-semitrailer combination, regenerative braking system, antilock braking control, braking stability
