A shift control method for a vehicle when a controller area network (CAN) communication fails according to the present invention is a shift control method for a vehicle when CAN communication fails, in which a transmission control unit is provided to communicate with a motor controller via a CAN communication line and a local interconnection network (LIN) communication line. The method comprises: a failure detecting step for detecting whether the CAN communication fails by the transmission control unit; a gear shift detecting step for detecting whether or not a target gear shift changes by the transmission control unit when the CAN communication failure is detected as an implementation result of the failure detecting step; and a gear engaging step for controlling to engage a target gear by driving a gear actuator by the motor controller through the LIN communication line by the transmission control unit when the target gear shift changes as an implementation result of the gear shift detecting step.
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.
