Abstract:
1. A method of controlling a wastegate during cruise mode in a combustion device, including a control unit, a throttle angle sensor, and a sensor associated with at least one of a vehicle speed and a cruise mode, the method comprising the steps of: receiving information from the throttle angle sensor at the control unit; wherein when the control unit receives information associated with a measured throttle angle received via the throttle angle sensor, the control unit performs the steps of: receiving information about current cruise conditions at the control unit from the sensor associated with the at least one of the vehicle speed and the cruise mode; wherein when the control unit receives information associated with a constant cruise condition from the sensor associated with the at least one of the vehicle speed and the cruise mode, the control unit performs the steps of: controlling the throttle valve to maintain the throttle angle at a wide open position; determining the power necessary to maintain the current cruise conditions; selecting an intake air volume required to provide the necessary power; and controlling the wastegate to achieve the selected intake air volume.
