PURPOSE: To improve a feeling of driving a vehicle by setting a target engine rotating speed according to the opening and closing speed of an accelerator to adjust the transmission gear ratio of a continuously variable transmission, thereby increasing and decreasing load of an engine. CONSTITUTION: When the opening and closing operation speed detected by an accelerator opening and closing speed detecting part 10 is a designated speed or less, a first target engine rotating speed setting part 101 sets the target engine rotating speed to approach the final achievable engine rotating speed. On the other hand, in case of sudden open operation above designated speed, a second setting part 102 sets a target engine rotating speed so that the transmission gear ratio is reduced to enable kick-down acceleration. In case of sudden close operation over the designated speed, a third setting part 103 sets a target engine rotating speed so that the transmission gear ratio is reduced to apply the engine brakes. The transmission gear ratio of a transmission 1 is adjusted by a transmission gear ratio adjusting part 105 so that the actual engine rotating speed reaches a target value to increase and decrease the engine load. Thus, a feeling of driving a vehicle can be improved. |
