The invention discloses a double-MCU chassis domain controller. The double-MCU chassis domain controller comprises a first microcontroller and a second microcontroller, the first microcontroller comprises a sensor signal processing module, a communication module, a steering redundancy module and a braking redundancy module; the second microcontroller comprises a function operation module; when the steering function operation of the second microcontroller fails, the steering redundancy module recalculates the steering control and outputs a steering redundancy control instruction; and when the brake function operation of the second microcontroller fails, the brake redundancy module recalculates the brake control and outputs a brake redundancy control instruction. Compared with the prior art, under the condition that the advantages of high control efficiency and the like of the centralized chassis domain controller are exerted, the risk of braking and steering failure is reduced, the processing load of the controller is reduced, and the risk of operation failure of the controller is reduced.

    本发明公开了一种双MCU底盘域控制器,包括第一微控制器和第二微控制器;所述第一微控制器包括传感器信号处理模块、通信模块、转向冗余模块和制动冗余模块;所述第二微控制器包含功能运算模块;所述转向冗余模块在第二微控制器的转向功能运算失效时,对转向控制进行重新计算并输出转向冗余控制指令;所述制动冗余模块在第二微控制器的制动功能运算失效时,对制动控制进行重新计算并输出制动冗余控制指令。与现有技术相比,本发明在发挥集中式底盘域控制器控制效率高等优点的条件下,降低了制动及转向失效的风险,降低了控制器处理载荷及降低了控制器运算失效的风险。
