본 발명에 따른 차량의 CAN통신 고장 시 변속제어방법은 변속기제어유닛이 CAN통신라인 및 LIN통신라인을 매개로 모터제어기와 통신하도록 마련된 차량의 CAN통신 고장 시 변속제어방법에 있어서, 변속기제어유닛이 CAN통신의 고장 여부를 감지하는 고장감지단계; 고장감지단계 수행결과, CAN통신 고장을 감지한 경우, 변속기제어유닛이 목표변속단이 변경되는지 감지하는 변속단감지단계; 및 변속단감지단계 수행결과, 목표변속단이 변경될 경우, 변속기제어유닛이 LIN통신라인을 통해 모터제어기가 기어 액츄에이터를 구동시켜 목표단기어를 체결하도록 제어하는 기어체결단계;를 포함할 수 있다.
A shift control method for a vehicle when CAN communication fails is provided to make a transmission control unit communicate with a motor controller via an LIN communication line. The shift control method includes: a failure sensing step of sensing, by the transmission control unit, whether the CAN communication fails; a shift stage sensing step of sensing, by the transmission control unit, whether a target shift stage is changed when the CAN communication failure is sensed as a performance result of the failure sensing step; and a gear engaging step of controlling, by the transmission control unit, the motor controller to drive a gear actuator through an LIN communication line so as to engage a target stage gear when the target shift stage is changed as the performance result of the shift stage sensing step.
