VEHICLE CLUTCH CONTROL METHOD AND VEHICLE CLUTCH CONTROL DEVICE

A clutch control method for a vehicle 1 is used in the vehicle 1 that has a second clutch mechanism 21 and a second clutch position sensor 52, which detects an engagement of the second clutch mechanism 21. The clutch control method for the vehicle 1 comprises executing an engagement of the second clutch mechanism 21 when the magnitude of the differential rotation of the second clutch mechanism 21 is less than or equal to a first prescribed value A1, and setting the target value of the differential rotation at the time of rotation synchronization to a second prescribed value A2, that is, offsetting the first prescribed value A1 to the larger side, at the time of failure of the second clutch position sensor 52, and then determining engagement of the second clutch mechanism 21 based on the differential rotation.
