Beschreibung
Zusammenfassung:	A method for using Kalman filter to estimate crank angle values and crank angular speeds, including the Kalman filter is installed in the estimation system of rotation dynamic of the engine. In the estimation system has an external circuit, an engine's torque estimation and an engine's torque load estimation can provide for values into an internal estimation equation and an observation matrix so as to estimate the crank angle values and crank angular speeds, and then transmitting into the engine control unit to proceed accurate control includes digital ignition, fuel injection, estimation of engine torques and malfunctions diagnoses in engine performance.
