Abstract

A hybrid vehicle includes an internal combustion engine coupled to a combined starter/motor/generator which is, in turn, coupled to a transmission of the vehicle. The starter/motor/generator is coupled to a high voltage battery pack via an inverter and to a deployable power output panel for serving loads external to the vehicle. Whenever external loads are to be powered, a control unit automatically places the vehicle in PARK, or alternatively activates an electrical parking brake system to hold the vehicle stationary.
