Abstract

PURPOSE:To economize energy, by driving an electric motor when a transmission is in the low or reverse position and a steering wheel is turning. CONSTITUTION:When a gearshift 18 is in the low position P1 or reverse position R, a signal S1 or S2 is applied to the OR circuit 20 of a controller 17 to supply an output signal S4. When a steering wheel 5 is turned under that condition, it is found out by a steering sensor 19 to apply a signal S3 to an AND circuit 21. When the signal S1 or S2 and the signal S3 are both applied to the AND circuit 21, an actuation signal S5 is sent out. As a result, a motor 2 is electrically coupled to a battery 16 to drive the motor and a valve 7 is shifted to supply pressurized oil to a power cylinder 4 by an oil pump 3.
