The invention provides a four-wheel-drive system exception handling method and device, electronic equipment and a vehicle, and the method comprises the steps: judging whether a transfer case motor has an open circuit exception and a short circuit exception or not under the condition that a four-wheel-drive system is in a working state; when short circuit abnormity occurs, a first fault code is recorded, the vehicle is controlled to be kept in the current driving mode, and response to the four-drive mode switching instruction is stopped in the current power-on cycle; when the open circuit abnormity occurs, recording a second fault code and controlling the vehicle to keep the current driving mode; when the second fault code is recorded, the response to the four-drive mode switching instruction is stopped, and whether the transfer case motor returns to normal or not is judged; and clearing the second fault code and recovering the response to the four-drive mode switching instruction when the four-drive mode switching instruction returns to normal. According to the method, when the transfer case motor has the open circuit abnormity capable of being recovered quickly, the fault code can be cleared in the current power-on cycle, the vehicle does not need to be powered off and then powered on, and the anti-interference capability of the four-wheel drive system abnormity processing process is improved.
本申请提供一种四驱系统异常处理方法、装置、电子设备及车辆,该方法包括:在四驱系统处于工作状态的情况下,判断分动器电机是否出现开路异常和短路异常;当出现短路异常时,记录第一故障码并控制车辆保持当前驱动模式,且在当前上电循环内停止响应四驱模式切换指令;当出现开路异常时,记录第二故障码并控制车辆保持当前驱动模式;在记录第二故障码时,停止响应四驱模式切换指令并判断分动器电机是否恢复正常;当恢复正常时,清除第二故障码,恢复对四驱模式切换指令的响应。本申请可以在分动器电机出现可以快速恢复的开路异常时,在当前上电循环清除故障码,无需对车辆进行下电再上电,提高了四驱系统异常处理过程的抗干扰能力。
