The invention discloses an automobile controller area network (CAN) bus system and a short circuit control method thereof. The automobile CAN bus system comprises a power twisted pair, a bodywork twisted pair, an engine electronic control unit (ECU) and a bodywork controller; the power twisted pair is electrically connected with the bodywork twisted pair; the engine ECU is electrically connected with the power twisted pair; and the bodywork controller is electrically connected with the bodywork twisted pair. The automobile CAN bus system further comprises a voltage detecting unit and an automatic switch unit; the voltage detecting unit is respectively and electrically connected with the bodywork twisted pair and the bodywork controller; the automatic switch unit is respectively and electrically connected with the power twisted pair and the bodywork controller; the voltage detecting unit is used for collecting the voltage values of the bodywork twisted pair and outputting to the bodywork controller; and the automatic switch unit is used for receiving the control signals of the bodywork controller and controlling the connecting and breaking of the power twisted pair and the bodywork twisted pair. The automobile CAN bus system and the short circuit control method are capable of reducing the probability of the abnormal deceleration of the engine caused by the twisted pair short circuit.
