摘要
针对分布式电动汽车,在弯道制动过程中,既能保证车辆行驶稳定性又能兼顾制动能量回收,文章提出一种带稳定性加权系数的制动力矩分配方法,以驾驶员制动意图和路面附着情况为参考条件得出稳定性加权系数,将系数代入系统目标函数中,求出各车轮的最佳制动力矩,最后利用Carsim/Simulink联合仿真对分配算法进行验证,结果显示文章所提出的分配策略能使分布式电动车辆在转弯制动时,制动力矩分配既能满足稳定性需求又能使在当前工况下经济性能最大化。
Based on the characteristic of distributed electric vehicle, a braking torque distribution method with the stability of the weight coefficient was proposed, which can combine stability and economy. Driver＇s braking intention and road adhesion are the reference conditions for stability coefficient, the coefficient is substituted into the objective function, obtained the optimum braking torque of each wheel, finally using Carsim/Simulink to verify the algorithm, results show that the algorithm can not only meet the demand of stability in the current conditions and make economic performance maximization.
