摘要
针对一种型号的小型汽车制动能量再生系统,进行了制动减速和起步加速过程相关参数建模,利用Matlab软件对此车制动能量回收及能量释放过程的车辆速度v、加速度a、液压蓄能器气囊压力p、体积V进行了仿真。通过对仿真结果的分析,得出的结论为:在制动减速过程,所选择的蓄能器能满足制动减速过程吸收完制动能量的要求;在起步加速过程,该蓄能器利用所储存的能量能够使该小型汽车起步加速到一定车速,从而满足车辆倒拖发动机,使发动机高速自行起动的要求。
A kind of regenerative braking system for a car was studied. The parameters of the car were modeled when the car broke or started-up. The car＇s speed v, acceleration a, the hydraulic accumulator＇s pressure p and volume V were simulated with Matlab while the car broke and started-up. The hydraulic accumulator can absorb all of the braking energy when braking and the energy stored in the hydraulic accumulator can drive the car to a certain speed so as to make the car start-up itself.
