Summary: | A method is disclosed for predicting a throttle position in a vehicle. A crank position sensor generates a signal indicative of engine speed received by an Electronic Control Unit (ECU) which calculates the engine speed based on this signal. The throttle position is estimated based on a filtered average engine speed value and a rate of change of the engine speed. The predicted throttle position is used with the engine speed for calculating the ignition timing. This method can eliminate the need of a throttle position sensor in a vehicle. |
