The present invention relates to a vehicle such as a forklift in which a hydraulic pump for driving the fork is driven by the same engine used to provide motive power to the vehicle. A inching control is provided in cases where an automatic transmission is employed for shifting the gears of the vehicle. The inching control controls the clutch to allow separate control of the motive system and cargo handling system of the vehicle. This control must be operated by an operator through the inching pedal. In the fork lift, the clutch plate wears excessively and therefore the relation between the amount of depressing of the inching pedal and engagement of clutch changes abruptly. The present invention discloses a technique to adequately measure the clutch position and for compensating for control of the clutch by always keeping constant the relation between the amount of depression of the inching pedal and the amount of engagement of the clutch.
