Patent ID: 7130731

Claim:
An automatic stop/start controller for a vehicle having an engine, a motor generator to drive the engine, an automatic transmission which includes frictional drive engaging elements, and an oil pressure pump which generates oil pressure to engage and disengage said frictional drive engaging elements, said automatic stop/start controller permitting the engine to stop and start without operation of an ignition key, wherein, at start of the engine without operation of the ignition key and after said engine is started to drive by said motor generator of which the amount of torque is variably set based on a determination as to whether the throttle opening angle is at an idle opening angle, the controller corrects to increase the torque generated by said motor generator according to the degree of engagement of said frictional drive engaging elements of said automatic transmission, and starts the fuel supply to the engine when the degree of engagement of the frictional drive engaging elements exceeds a predetermined threshold, the frictional engaging elements being driven by said oil pressure generated by the oil pressure pump, wherein the oil pressure pump comprises a mechanical pump that is driven by a driving force of the engine.
