摘　　要：“发电机—二极管整流—逆变器—牵引电机”的电动轮车辆动力传递系统,在下坡制动工况时,可通过能量反向流动实现部分制动能量的回收再利用从而降低燃油消耗。针对电动轮交-直-交传动系统,引入发动机反拖制动的理论,通过外部转速传感器间接观测转子频率,以及过零点检测相位的方法来达到定子旋转磁场与转子转速同步的目的,实现发动机反拖平稳启动;当下坡缓行时,采用整流逆变模块,实现能量双向传递,实现发动机反拖;设计发动机制动反拖控制系统,建立反拖制动功率计算数学模型,并搭建发动机反拖实验平台,对控制系统进行验证;实验结果表明所提出的实现逆变器对旋转电机启动的控制方案简单易行,可靠性高,为实车设计提供了理论依据和实验数据。The power transmission system of electric wheel vehicle with“Power generator-diode rectifier-inverter-traction motor”which can achieve part of the braking energy recycling and reduce fuel consumption through the reverse flow of energy in the downhill braking conditions.For AC-DC-AC transmission system of electric wheel vehicles,In order to achieve the engine anti-drag starting smoothly through the introduction of the theory of Engine Anti-drag Braking and the observation of the rotor frequency by external speed sensor,in addition to that zero-crossing detection phase method to achieve the stator rotating magnetic field and rotor speed synchronization purposes.Through use the rectifier inverter module to achieve energy bi-directional transmission and to achieve engine anti-drag when the vehicle goes downhill slowly.In the article,design of engine brake anti-drag control system and the establishment of anti-drag brake power calculation mathematical model,also build the engine anti-drag test platform to verify the control system.The experimental results show that the proposed control scheme for the start of the inverter is simple and reliable,which provides the theoretical basis and experimental data for the actual vehicle design.
