摘　　要：以某型纯电动车为研究对象,旨在探究电动汽车处于滑行工况时的能量回收规律。判断了汽车是否处于滑行工况,分析了能量回收的条件和影响因素,确定了电机目标转矩和转矩变化规律;运用Matlab/Simulink实现汽车以不同挡位和初速度开始滑行时的建模仿真,并完成实车测试验证。结果表明:电机目标转矩与实车测试转矩基本一致,且在适当的范围内,滑行车速越高且挡位越高时能量回收率越大。Taking an electric vehicle as the research object,the law of energy recovery was explored when the electric vehicle is in the sliding condition.The sliding condition was judged,the condition of the energy recovery and the influencing factors were analyzed,and the law of torque and the motor torque were determined.The model of the vehicle with different gears and initial velocity was established and simulated by Matlab/Simulink,and the real vehicle test verification was completed.The results show that the target torque of motor is basically the same as that of the actual vehicle test,and the higher the glide speed and the higher the gear,the higher the energy recoveryisinthe appropriate range.
