<p>PURPOSE:To accurately detect abnormality in a first detecting means by judging trouble in the first detecting means when the first detecting means does not output even at outputting from a second detecting means, during learning operation by a clutch learning means or at starting operation of a vehicle. CONSTITUTION:When a starter motor 20 in unstable condition of the electric system is being driven, an engine speed sensor 9 (first detecting means) to detect engine speed can not be checked. A trouble judging means 40d judges trouble in the sensor 9, when the sensor 9 does not output even there is output from an input shaft sensor 5a (second detecting means) during clutch learning operation to engage the clutch without fail or at starting operation of a vehicle.</p> |
