摘要
电喷汽油发动机控制单元(ECU)是电控汽车的核心,该ECU供电是否稳定,直接影响系统的正常工作。其供电过程包括稳压过程、调压过程和正常供电过程。外电路向ECU的供电过程一般采用继电器控制主电源、主电路双路供电、常电源持续供电、多路搭铁控制等方式,保证发动机控制系统的稳定供电和搭铁良好等要求。
The gasoline engine control unit is the core of EV. Whether its power supply is stable or not concerns the normal working of the system, The power supplying process includes voltage stabilizing, regulating and normally supplying. The power supply process to ECU from external circuit adopts various ways to ensure the supply stability and the good grounding.
