<p>PURPOSE:To improve efficiently the startability and the accelerationability in the case of the lower of the output of an engine at the high ground, etc., by correcting the characteristics of the clutch torque to be reduced in response to an amount of the lower of the atmospheric pressure when the atmospheric pressure detected by an atmospheric pressure sensor lowers at the time of starting at the high ground, etc. CONSTITUTION:At the time of starting at the high ground, the engine torque also lowers in response to the lower of the atmospheric pressure, and the atmospheric pressure P detected by an atmospheric pressure sensor 40 is input to a correction factor computing unit 41 so as to compute the correction factor K with K - P/760 in relation of the atmospheric pressure P and the 760 mmHg of the atmospheric pressure at the flat ground. And a current correcting unit 42 is provided at the output side of a starting mode current setting unit 35, and Ic X K of the correction is performed against the clutch current Ic output from the starting mode current setting unit 35. Thereby, the clutch torque characteristics is controlled to be reduced in response to an amount of the lower of the atmospheric pressure, and the clutch torque coincides with the stall engine speed as same as that of the flat ground can be obtained.</p> |
