Abstract: A method of controlling an idle speed of an engine of a vehicle includes evaluating a plurality of instantaneous current requirements of the vehicle at respective points in time. The engine is a variably set to idle speeds based upon the evaluated instantaneous current requirement of the vehicle such that the idle speeds are above minimum engine idle speeds required to produce alternator output currents that satisfy the evaluated instantaneous current requirements of the vehicle.

Abstract: The invention relates to automated hardware in the loop testing. A method of automated diagnostic testing is described as monitoring, modifying, overwriting, providing and/or providing read-only access to input data given to a tested application and output data provided by a tested application to compare a desired relationship between input data and output data. A preferred system includes a communication network with a preferred method including a controller area network to associate a test controlling system to a tested application. An automated diagnostic testing system comprises a test controlling system operably coupled to a tested application.
