<p>PROBLEM TO BE SOLVED: To prevent the engagement shock of an one-way clutch in an automatic transmission without depending on a lock-up-off, in the conversion from the coasting travelling to the power-on travelling. SOLUTION: In the conversion to the power-on travelling, where the coasting travelling is determined in the last time in 21, and the pedalling of the accelerator pedal is determined this time in 22, the acceleration &alpha of the rotation of an engine is determined in 26, and the time &Delta T to the rotational synchronization necessary for the engine speed to reach the transmission input engine speed N13 determined from the transmission output engine speed and the gear ratio of the selected transmission stage, is presumed on the basis of the determined acceleration &alpha and the present engine speed NEN in 27. The response delay &Delta Te from the ignition timing delaying operation to the lowering of the engine output is retrieved in 36, the engine output lowering control for preventing the engagement shock of an one-way clutch by the ignition timing delaying operation in 39, is started when &Delta T<=&Delta Te is determined in 37, and the operation is continued till the time when the time corresponding to the one-way clutch engagement shock generating time &Delta TOWC has passed in 40.</p> |
