  • Engine idling reduction system
    Patent number: 11598305
    Abstract: In one aspect, a method for controlling an engine system includes starting the engine system, activating an engine idling reduction mode allowing automatic shutdown and automatic restarting of an engine, disallowing automatic shutdown of the engine within the engine idling reduction mode if a state of charge of a voltage source is below a charge limit for permitting automatic shutdown of the engine, and modifying the charge limit as a function of a number of starts of the engine. Other aspects include a method for disallowing automatic shutdown of an engine if a voltage source has not achieved a fully charged condition, a method of triggering an automatic restarting of an engine, if the engine is automatically shutdown, based on at least two separate indicators of engine temperature, and a method of disallowing automatic shutdown of an engine if ambient temperature is less than a predetermined value.

  • Automatic start-up of an auxiliary power unit
    Patent number: 7290517
    Abstract: An auxiliary power unit automatic start-up system is configured to assist a main engine start of a machine. The auxiliary power unit automatic start-up system may include an auxiliary power unit and a controller. The controller may monitor a parameter of the machine, automatically start the auxiliary power unit if the parameter is outside a first predetermined range, and bring the parameter within a second predetermined range using the auxiliary power unit.
