混合动力型电动汽车发动机转速自动控制系统

Automatic Control System of Engine Speed in Hybrid Vehicles

发动机在混合动力型汽车中是为电动机提供动力的总成 为保证发电机输出稳定的电压和发动机处于最佳工作状态 ,其转速必须稳定在给定值 文中介绍了发动机转速自动控制的原理、硬件电路和调试方法 。

The engine in the hybrid vehicle provides all the power. To make it output a stable voltage and work in the optimum state, the engine speed must be controlled in a given value. This paper presents its working principle, hardware circuit and debugging method of an automatic control system of engine speed of the hybrid vehicle.The factors that influence the system stability and control accuracy are also pointed out.
