Abstract
A failure detection system for accurately detecting a failure of a clutch. A clutch actuation mechanism changes the relative positions of drive-side and driven-side members of the clutch. A position detector detects a position of the clutch actuation mechanism as a clutch position. A control unit obtains torque transmitted from the drive-side member to the driven-side member as actual transmission torque. The control unit detects a failure of the clutch based on the actual transmission torque and the clutch position.
