ABSTRACT:
A system and method [of] for automatically starting and stopping an engine of a [truck] vehicle to conserve fuel while maintaining the engine in a ready-to-start condition, and while controlling the temperature of [a truck sleeper unit] an interior portion of the vehicle. The method includes the steps of selecting predetermined system parameters [via a password accessible interactive program, providing a first switch for selecting an automatic engine start-stop operating mode, providing a second switch for selecting an automatic temperature control mode for the truck sleeper unit, and providing safety apparatus which indicates when the truck engine may be safely operated in the automatic engine start-stop operating mode.] The method further includes the step of overriding the [ignition switch] operator control of the engine in response to a predetermined condition when [the] a first switch selects the automatic operating mode and the safety apparatus indicates the truck engine may be safely operated in the automatic operating mode. The engine is started and stopped automatically while the ignition switch control of the engine is being overridden by the overriding step, to maintain the engine in a ready-to-start condition, regardless of the selection of the second switch, and additionally controlling the temperature of the [sleeper unit,] vehicle interior when [the] a second switching means selects automatic temperature control. The overriding step is terminated in response to a predetermined condition, restoring [ignition switch] operator control of the engine, and preventing automatic re-starting of the engine while the [ignition switch] operator is in control of the engine.
