摘要
为提高纯电动汽车的再生制动能量回收率,在分析基于理想制动力曲线和基于ECE法规的电动汽车前后轮制动力分配控制策略的基础上,根据制动强度和储能元件荷电状态的大小,提出了一种基于模糊逻辑的前后轮制动力分配控制策略,以实现制动能量的高效回收利用和良好的汽车制动稳定性。对该控制策略在电动汽车仿真软件ADVISOR2002下进行了仿真,仿真结果表明,该制动力分配控制策略提高了再生制动能量的回收率,同时也能改善汽车的制动稳定性。
In order to enhance the recycling efficiency of regenerative braking energy for pure electric vehicles ( PEV), the electric car front and rear braking force distribution control strategies based on ideal braking force curve and ECE regulations are analyzed, according to the braking intensity and the state of charge (SOC) of the energy storage element, a novel control strategy of braking force distribution based on fuzzy logic is proposed to achieve the high efficiency recycling of braking energy and a good braking stability. The simulation of the fuzzy control strategy for braking force distribution is carded out in typical driving cycle by the electric vehicle simulation software ADVI2SOR2002. The simulation results show that the braking force distribution control strategy can improve the recycling efficiency of regenerative braking energy and the car's braking stability.
