<p>PROBLEM TO BE SOLVED: To prevent degradation of the transmission feeling by controlling the clutch contact so that the vehicle acceleration is in a range determined by the target acceleration map during the shift-up and by the target deceleration map during the shift-down. SOLUTION: During the shift-up, the contact quantity is obtained by a transmission clutch contact quantity map 5-3 based on the value of an accelerator opening sensor 9, and a clutch 13 is advanced to the position slightly toward the contact side from the partial clutch engagement position by a controller 5. The speed of an engine 11, the number of revolution of a T/M 16, and the accelerator opening are read, the upper and lower limit values of the target acceleration range are obtained from a target acceleration map 5-1, and the clutch 13 is kept in a contact condition if the vehicle acceleration is larger than the upper limit value. If the vehicle acceleration is smaller than the lower limit value, the clutch 13 is advanced in the contact direction by the minimum controllable unit, and the value of a counter 5-4 is increased when the number of revolution of the T/M 16 is approximately equal to that of the engine 11 in the range. When the value reaches the prescribed value, the clutch 13 is advanced to a completely contact position. The operation is similar during the shift-down.</p> |
