  • Learned airflow variation
    Patent number: 6957140
    Abstract: A throttle control system for a vehicle includes a driver input that generates a control signal and a control module that generates a throttle control signal based on the control signal. The control module determines whether the throttle control signal is within one of a first and a second region, determines a compensation factor from a first look-up table when the throttle control signal is within the first region and determines the compensation factor from a second look-up table when the throttle control signal is within the second region. The control module calculates a compensated throttle control signal based on the compensation factor.

  • Electronic throttle control (ETC) idle area request security
    Patent number: 6810853
    Abstract: An electronic throttle control (ETC) system to control an idle speed of an engine includes an accessory that increases a load on the engine and a controller that generates an idle request signal based on the increased load. The controller compares the idle request signal to an idle maximum signal and sets an idle command signal equal to the idle request signal if the idle request signal is less than the idle maximum signal. The controller determines the idle command signal based on the idle request signal, a previous idle command signal and the idle maximum increase signal if the idle request signal is greater than the idle maximum signal.
