ABSTRACT:
An elevated idle speed control is disclosed for use with an internal combustion engine on a vehicle. The control includes an electronic controller connected to a brake pedal sensor, a clutch pedal sensor, an engine speed determining means, a vehicle speed determining means, and a high idle mode selection means. The control permits a vehicle operator to select a desired high idle speed within a default high idle speed and a maximum high idle speed. The control permits the operator to select a high idle mode as a function of signals from said brake pedal sensor, said clutch pedal sensor, the engine speed determining means, the vehicle speed determining means and the high idle mode selection means.
