PROBLEM TO BE SOLVED: To provide a shift shock absorber that has reconciled such control as making a span of shift time into a desired value and any suppression over peak torque in time of gear shifting even in case of an automatic transmission where output torque is combined with a barrack-cylinder direct injection gasoline engine. SOLUTION: A deviation between shift time found out of an operation part 5 and this shift time desired value at a data part 6 is calculated by a comparing part 7, and a torque-down compensated variable to get rid of this deviation is found out by a torque down compensated variable operation part 8, while a torque-down compensated with the last one as far as the compensated variable is commanded to an engine 1 by a torque-down value operation part 9 as the torque-down value. On the other hand, a controller 4 calculates the engine output torque, thereby making the clamping pressure in a frictional element come to be clamped at the time of gear shifting correspond to this engine output torque. |
