Driver override control logic for a motor vehicle powertrain control system |
摘要 |
A driver override of a cruise control system is detected and employed to suitably alter the powertrain controls. A driver override of the cruise control system is detected by a lack of correspondence between the engine throttle position and the cruise control servo position, taking into account any hysteresis and lash which may occur in the linkage coupling the servo to the throttle. The lash is determined by storing the measured servo position whenever the measured throttle position is equal to a predefined value, and the controller responds during a detected driver override by instituting normal or noncruise related control parameters. This control permits the cruise control parameters to yield smooth control without unnecessary shifting while retaining a more responsive control during driver override conditions. |
