PURPOSE:To eliminate flying out feeling generated due to elimination of accelerating load immediately after change-over by providing a second adjusting means adjusting the engine rotational speed based on the car speed data from a car speed detecting means. CONSTITUTION:A detector 7 for detecting step-in angle outputs running operation amount signal SG1 and the signal SG1 is output in a swash plate function generator 9. And the generator 9 selects an optimum function based on the existent running condition, and outputs speed change ratio data E corresponding to the signal SG1 to a multiplicator 10 according to the selected function. A correcting function generator 18 outputs corrected data D and the data is output in a multiplicator 19. The multiplicator 19 multiplies the corrected data D and rotational speed data A, and the resultant corrected rotational speed data Ax is output in a slot actuator 5. An engine 2 is controlled to the rotational speed corrected smaller than that based on the data A. |
