The embodiment of the invention discloses a vehicle controller communication circuit and a vehicle controller using the same. The vehicle controller communication circuit provided by the embodiment of the invention comprises a communication bus used for transmitting information among electric control units in a vehicle, the communication isolation transceiver is used for receiving the information and converting the information into a signal level or a logic level; and the circuit protector is used for limiting instantaneous voltage or current in a vehicle controller communication circuit. Wherein the communication isolation transceiver and the circuit protector are connected in parallel with the first communication bus and the second communication bus. According to the vehicle controller communication circuit provided by the embodiment of the invention, the information is transmitted and received through the communication isolation transceiver with the isolation, so that the transmitting and receiving speed is higher, the isolation voltage is higher, and the communication of the vehicle controller communication circuit is more stable. In order to prevent the communication circuit from being damaged due to instant electrical high-voltage impact, a circuit protector is used in the communication circuit of the vehicle controller to protect the circuit.
本发明实施例公开了一种车辆控制器通信电路和应用该电路的车辆控制器。本发明实施例的车辆控制器通信电路包括用于在车辆内各电控单元之间传输信息的通信总线、用于接收信息并将信息转化为信号电平或逻辑电平的通信隔离收发器以及用于限制车辆控制器通信电路中的瞬时电压或电流的电路保护器。其中，通信隔离收发器、电路保护器与第一通信总线和第二通信总线并联。本发明实施例的车辆控制器通信电路通过自带隔离的通信隔离收发器对信息进行收发，使得收发速度更快，隔离电压更高，从而使车辆控制器通信电路的通信更加稳定。并且为了防止通讯电路受到瞬间电气高压打击而受到损坏，车辆控制器通信电路中还使用电路保护器对电路进行保护。
