Gear Position Failure Detection Device
Abstract: In this gear position failure detection device (1), a clutch state estimation unit (17g) includes a release area value calculation unit (17i) for calculating, on the basis of the output of a crank angle sensor (21), the value of a release area which is defined by the rotation speed of an engine and the valve opening degree of an intake control valve provided in the engine, and in which a main clutch (61) may be disengaged or half-clutched. When the throttle opening degree calculated on the basis of the output of a throttle opening degree sensor (22) deviates from the release range, the clutch state estimation unit (17g) determines that the main clutch (61) is connected, and allows the failure determination unit (17h) to execute a failure determination.
