Abstract
A method and system of throttle calibration control is presented that includes a TPS designed to provide an output indicative of throttle plate position when the throttle plate is opened and provide an output of throttle actuator position when the throttle plate is closed. The TPS output is received by an ECU to control subsequent engine operation. When an input is received from the TPS indicating that the throttle actuator is within a pre-set idle throttle position range and below an idle position benchmark, the ECU automatically reestablishes present and subsequent engine operation.
Claims26
A throttle calibration control configured to:
- determine if throttle actuator position is within an idle position range;
- if so, maintain the throttle actuator position as an idle position benchmark for subsequent engine operation until a subsequent throttle actuator positioning more idle than the idle position benchmark;
- and
- establish a WOT position benchmark for subsequent engine operation based on a fixed angular position from the idle position benchmark.
A method of throttle control calibration comprising the steps of:
- determining if throttle actuator position is within an idle position range;
- if so, maintaining the throttle actuator position as an idle position benchmark for subsequent engine operation until a subsequent throttle actuator positioning is in the idle position range and more toward idle than a previous idle position benchmark;
- and
- establishing a WOT position benchmark for subsequent engine operation based on a fixed angular position from the idle position benchmark.
A method of throttle control calibration comprising the steps of:
- determining if a throttle actuator position is within an idle position range;
- if the throttle actuator position is within an idle position range then comparing the throttle actuator position to an idle position benchmark;
- if the throttle actuator position is lower than the idle position benchmark, then establishing the throttle actuator position as the idle position benchmark;
- and
- establishing a WOT position benchmark for subsequent engine operation based on a fixed angular position from the idle position benchmark.
