Abstract: A startup condition monitoring device may have a sensor module for detecting at least one control parameter of a machine. The device may have a data acquisition unit communicatively coupled to the sensor module, the data acquisition unit being configured to receive the at least one control parameter from the sensor module, store the at least one control parameter, and transmit the at least one control parameter to a processor communicatively coupled to the data acquisition unit. The processor may be configured to: determine a performance standard for the machine using a physics-based model and historical data; adjust the performance standard using a machine learning model and additional historical data to account for at least one variation; generate at least one calculated parameter based on the adjusted performance standard; and display a startup health indicating at least one startup condition based on the determined at least one calculated parameter.

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.

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.
