摘要: 为了保证制动安全性,需要将再生制动与原车的ABS系统进行协调控制。基于半挂汽车列车按固定比值分配制动力的制动器结构,提出了适用于三轴车辆的最优能量回收控制策略。根据制动强度、蓄能状态与路面附着条件,分配三轴间机械摩擦与再生制动力,调节摩擦制动力以控制车轮滑移率。利用AMESim和MATLAB/Simulink建立了联合仿真模型。结果表明,协调控制策略可以使制动能量回收率在中低附着路面、中度制动工况下达到13.48%,同时三轴制动时的滑移率均维持在最佳范围内。

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
