PURPOSE:To enhance the accelerating characteristic of a vehicle, by controlling a hydraulic drive means for applying a differential resistant force to a differential limit mechanism through a control means in accordance with an accelerating condition detection signal so that a large torque which is necessary upon acceleration, is transmitted. CONSTITUTION:An accelerator depression amount detecting sensor 41 delivers a detection signal which corresponds to the depressed amount of an accelerator pedal depressed by the driver, to a control circuit 48 composed of a comparating signal generating circuit 49 for delivering a comparing signal Ei corresponding to the detection signal delivered from the sensor 41, a saw-shape wave signal generating circuit 50 for delivering a saw-shape wave signal Et, and a comparator circuit 31 for comparing these signals Et, Ei with each other and delivers a control signal P to a solenoid valve 36 in a hydraulic circuit. In association with the operation of the solenoid valve 36, hydraulic pressure at the hydraulic pressure port of a hydraulic actuator is controlled to have a hydraulic pressure in accordance with the depression amount of the accelerator pedal. |
