基于轻型混合动力车不同行驶模式的电机驱动系统研究

Investigation on the Motor Drive System of Hybrid Electric Vehicle in Various Driving Modes

在混合动力车上采用平顺行驶模式和急速行驶模式进行道路工况试验,对两种行驶模式下驱动电机的转速、扭矩、电流和温度等相关参数进行对比分析。结果表明:采用平顺行驶模式时电机实际电流相对比较平稳,且驱动电机绕线温度和逆变器温度均低于急速行驶模式,因此在平顺行驶模式下,驱动电机的性能相对比较稳定。

In this paper, the road test of hybrid electric vehicle （HEV） has been experimentally investigated when using various driving modes, the motor performance has been demonstrated through comparing the smooth driving mode and the rapid driving mode, which including the related parameters such as speed, torque, current and temperature. The results show that, the actual current of motor is relatively stable using the smooth driving mode, meanwhile, the temperature of winding coils and inverter was lower than those of the rapid driving mode. Through comparing, the motor performance has been relatively stable using the smooth driving mode.
