And a pedal operation amount detection unit 12 that detects the operation amount s of the accelerator pedal 11. In the present invention, the torque converter (2) speed ratio detecting unit that detects a speed ratio e of an input shaft and an output shaft (14, 15), the hydraulic load pressure detector 16 and the speed stage detection unit that detects a low speed stage of the transmission can change the speed stage to the low speed stage and the high-speed stage (3) 18 and at least a pedal operation amount detecting the load pressure P of the pump (6) If s is the predetermined value s1 or more, and the speed ratio e is the predetermined value ea or less, and the pump load pressure P is a predetermined value Pa or more, and the transmission (3) of the low speed stage is detected status of rate limiting condition is established, the prime mover ( 1) the maximum rotation speed and a speed limiting unit 10 that limits the low speed side.
