INCREASED RESOLUTION ELECTRONIC THROTTLE CONTROL APPARATUS AND METHOD |
摘要 |
An apparatus and method for controlling a throttle of an electronic throttle control-equipped engine including providing a throttle position feedback signal as a function of integer counts, each of the counts representing a resolution of a predetermined angle of actual throttle position, providing a desired throttle position command as a setpoint value being a function of half counts and generating an error signal representing a difference between the desired throttle position command value and the throttle position feedback signal value. A relay output signal is generated in response to the error signal, the relay output signal having one of two values depending upon a sign of the error signal and a direction of change of the error signal. A throttle actuator command is then generated as a function of the relay output signal value having a half count resolution.
