The invention relates to a redundant electronic stability control system, a control method and a vehicle, and relates to the technical field of vehicle control. The system comprises a controller; the first MCU is connected with the input end of the controller and used for controlling the controller; the first MCU is provided with four SPI channels, including a first SPI channel, a second SPI channel, a third SPI channel and a fourth SPI channel; the second MCU is connected with the input end of the controller, performs information interaction with the first MCU through a third SPI channel and is used for acquiring the control state of the controller, the working state of the first MCU and the vehicle state; when the first MCU fails, the second MCU takes over the controller; information interaction is carried out through the SPI channel, when one MCU fails, the other MCU is used for taking over the controller, and the control safety is greatly improved.
本发明涉及一种冗余电子稳定控制系统、控制方法及车辆,涉及车辆控制技术领域。该系统包括控制器;第一MCU,连接控制器的输入端,用于控制该控制器;第一MCU设置四路SPI通道,包括第一SPI通道、第二SPI通道、第三SPI通道、第四SPI通道;第二MCU,连接控制器的输入端,通过第三SPI通道与第一MCU进行信息交互,用于获取该控制器的控制状态,第一MCU的工作状态以及车辆状态;当第一MCU失效时,第二MCU接管该控制器;通过SPI通道进行信息交互,当一MCU失效时,另一MCU用于接管控制器,极大提高控制的安全性。
