摘　　要：汽车速度转速控制是汽车队列技术重要内容。通过引导车ECU采集发动机的CAN报文,并解析报文获得的转速数据,利用CAN总线把引导车的转速数据和油门踏板电压数据等传输给后随车辆。通过控制后随车油门踏板电压信号控制发动机转速,实现多台发动机的转速同步控制和车辆同步。控制算法综合了数字PID和模糊PID控制,可以对发动机转速进行比较精确的控制。Speed control is an important technology in Vehicle Road Train （VRT）. Engine speed can be obtained using CAN messages from ECU in the header vehicle engine. The trailer＇s speed must be controlled with an acceptable speed range. Voltage of acceleration pedal and the engine speed are transmitted from the header to trailers by the CAN- BUS. Engine speed is controlled by regulating voltage signal of acceleration pedal in the trailers. An engine controller is designed and a prototype is implemented. Combining a PID Controller and a Fuzzy Controller, a good controller of engine speed can be achieved.
