Abstract

The present disclosure relates to a method of controlling a vehicle. The method includes receiving a signal indicative of the vehicle being in a stop condition or in the process of stopping. The method also includes activating an auxiliary hydraulic pressurization system in response to the signal and regulating a hydraulic pressure in a hydraulic control system of a transmission. A drive unit is disabled such that a main pump of the hydraulic control system discontinues providing hydraulic pressure to the hydraulic control system. The hydraulic pressure is maintained at a hold pressure in the hydraulic control system by the auxiliary hydraulic pressurization system.
