The embodiment of the invention discloses a vehicle controller circuit board and a vehicle controller using the same. The vehicle controller circuit board is designed into a six-layer circuit board structure, the first layer, the fourth layer, the fifth layer and the sixth layer are signal wiring layers, the second layer is a ground wire layer, and the third layer is a power supply layer. The signal wiring layer comprises data communication circuit wiring, the data communication circuit wiring comprises a front-end loop and a rear-end loop which are isolated from each other, and the front-end loop and the rear-end loop are respectively connected with the second layer through resistors. According to the embodiment of the invention, the special power supply layer and the ground wire layer are adopted, the impedance of a power supply circuit is reduced, and the complete ground plane is combined with the design of the top layer and the bottom layer, so that good anti-interference performance is provided. Meanwhile, a front-end loop and a rear-end loop in the data communication circuit are subjected to independent isolation processing, and each loop is connected with a ground wire through a resistor, so that crosstalk between a signal wire of a high-speed signal and the ground plane is avoided.

本发明实施例公开了一种车辆控制器电路板及应用该电路板的车辆控制器。本发明实施例的车辆控制器电路板被设计为六层电路板结构，第一层、第四层、第五层和第六层为信号布线层，第二层为地线层，第三层为电源层。所述信号布线层包括数据通信电路布线，所述数据通信电路布线包括相互隔离的前端回路和后端回路，所述前端回路和所述后端回路分别通过电阻连接所述第二层。本发明实施例采用专用的电源层及地线层，减小了电源线路阻抗，完整的地平面结合顶层、底层的设计，提供良好的抗干扰性能。同时，将数据通信电路中的前端回路和后端回路做单独的隔离处理，且每条回路通过电阻与大地地线相连，避免了高速信号的信号线与地平面之间形成串扰。
