Abstract
A method for estimating crank angles and rotation speeds of an engine, having a signal processing unit to generate a dynamic sampling signal based on the tooth number signal of the crank detected by a crank angle sensor, an estimation unit designed by a discrete kinematic model and containing an estimator and a feedback gain matrix to read the dynamic sampling signal, and a crank rotation stroke discriminator allowing the signal processing unit to calculate a more precise crank dynamic sampling signal, so as to preclude external noises to interfering control of the engine.
