摘要
为了提高续驶里程,针对某款越野车改装的电动汽车制动系统,提出一种基于ABS的电-液并联制动系统。此系统采用固定比例的前后轴制动力分配方式,结合恒定充电电流与最大回馈功率复合的再生制动控制方式,以基于滑移率的PID控制ABS系统来调节电、液制动力比例,在确保制动安全可靠的同时实现制动能量回收。根据上述理论建立数学模型,并利用AMESim和Simulink进行联合仿真,在3种典型工况下分析制动性能和能量回收效率。结果表明:基于ABS的电-液并联制动系统综合制动性能良好,且3种工况下的一次制动最小能量回收效率分别达到28%、28%和11%。
In order to improve the driving mileage, an electric-hydraulic parallel brake system based on ABS is proposed for the electric vehicle braking system modified by a certain off-road vehicle. The system adopts a fixed proportion of front and rear axle braking force, combined with the regenerative braking control mode of constant charging cmTent and maximum feedback power, and abjusts the proportion of motor regenerative bra- king force and hydraulic braking force by PID control ABS system based on slip rate, and realizes braking ener- gy recovery while ensm＇ing braking safety and reliability. The mathematical model was established based on the above theory, and the joint simulation of AMESim and Sinmlink was used to analyze braking performance and energy recovery efficiency under three typical working conditions. The resuhs show that the comprehensive bra- king performance of the electro-hydraulic parallel braking system based on ABS is good, and the nfininmm en- ergy recovery efficiency of once braking under thine working conditions is 28%, 28% and 11%, respectively.
