摘要： A method to control the position of a throttle valve in the presence of a fault. The method works independently of throttle position in an open-loop mode. The method assures that the throttle plate will assume the default position if: 1) the return spring is functional and the motor is functional; 2) the return spring has failed but the motor is functional; or 3) if the return spring is functional but the motor has failed. This method does not need to detect loss of return spring functionality and it does not need to detect loss of motor functionality. The detected fault that initiates the action need not be related to either the return spring or the motor.

摘要： A throttle miswire detection system including a powertrain control module (PCM) coupled to a throttle actuator and a pair of throttle plate position sensors. In detecting miswires, the PCM sets the throttle plate to a default position in which a default position value is measured by the position sensors. The PCM then sets the throttle plate to a closed position in which a closed position value is measured by the position sensors. After recording the receiving measurements, the PCM computes a negative slope sensor difference and a positive slope sensor difference. The PCM calculates a slope ratio consisting of the positive slope sensor difference divided by the negative slope sensor difference. If the slope values or slope ratio are not within prescribed limits, then the PCM deactivates the throttle actuator.

摘要： A method is disclosed for ensuring operation of a motorized throttle. The presence of an obstruction, such as ice, is detected inside the motorized throttle. The obstruction is then removed within a predetermined time to free the motorized throttle. A new closed throttle position is then recorded as a zero degree reference from which to control a throttle plate to a desired angle.
