The invention discloses an automatic driving domain controller, a control method and a control system, the automatic driving domain controller comprises a control main board, a main controller chip, an auxiliary controller chip and an MCU chip are integrated on the control main board, and the main control main board is connected with various sensors; the main controller chip and the auxiliary controller chip are provided with a laser radar signal communication interface, a millimeter wave radar signal communication interface, an ultrasonic radar signal communication interface, a video signal communication interface, an inertial navigation signal communication interface and a network communication interface. The main controller chip and the auxiliary controller chip are redundant chips, the main controller chip and the auxiliary controller chip receive all sensor data at the same time and issue a whole vehicle control instruction to the MCU chip through an SPI bus at the same time, the MCU chip preferentially uses the control instruction of the main control chip, and meanwhile, the instruction of the auxiliary controller chip is set to be invalid; and if the MCU chip judges that the main control chip fails, the control instruction of the auxiliary controller chip is valid, and the MCU chip uses the control instruction of the auxiliary controller chip.
本发明公开了一种自动驾驶域控制器、控制方法及控制系统,包括控制主板,控制主板上集成有主控制器芯片、辅控制器芯片、MCU芯片,主控主板连接各种传感器;主控制器芯片和辅控制器芯片设有激光雷达信号通讯接口、毫米波雷达信号通讯接口、超声波雷达信号通讯接口、视频信号通讯接口、惯性导航信号通讯接口以及网络通讯接口;主控制器芯片和辅控制器芯片互为冗余芯片,主控制器芯片和辅控制器芯片同时接收所有的传感器数据,并同时通过SPI总线下发整车控制指令给MCU芯片,MCU芯片优先使用主控制芯片的控制指令,同时副控制器芯片的指令置为无效;若MCU芯片判断主控制芯片失效时,副控制器芯片的控制指令有效,MCU芯片使用副控制器芯片的控制指令。
