PURPOSE:To prevent an engine stop when the rear wheels are steered as the vehicle is stopped, by outputting a signal to increase the output of the engine when the steering is detected by a steering detecting means. CONSTITUTION:At oil feeding pipes 18 and 30, a front wheel side pressure switch 65 and a rear wheel side pressure switch 66 to detect that the hydraulic pressures in the oil feeding pipes 18 and 30 are increased more than specific values in an idle operation are furnished respectively. The detected signals of the pressure switches 65 and 66 are input to a control unit 100, and the fuel feeding amount to an engine E is increased by the signal to increase the output from the control unit 100. When the wheels are steered in the halting condition by operating the steering wheel in an idle condition, the front and the rear wheels are steered in the inverse phases. In this case, the pressure switches 65 and 66 detect that the hydraulic pressure in the oil feeding pipes is increased, the rotation frequency of the engine is increased by the signal from the control unit, the pumping ability of the hydraulic pump 20 is increased, and an engine stop can be prevented. |
