Abstract
The objective of the present invention is to provide a clutch disengagement control mechanism that is for a mechanical automatic transmission and that can perform clutch disengagement control at an optimal timing during both ordinary driving and low-speed driving at the verge of stopping. To this end, the present invention is provided with a vehicle speed measurement device (and, or), a brake-operation-speed measurement device (), a clutch operation device (), and a control device (). The control device () has: a function for generating a control signal that disengages the clutch from the clutch operation device () when the brake operation speed is at least a second threshold (B) in the case that the vehicle speed (X) is at least a first threshold (A); and a function for generating a control signal that disengages the clutch from the clutch operation device () when the brake operation speed is at least a third threshold (C) in the case that the vehicle speed (X) is less than the first threshold (A).
