Decoding the Engine Crank Signal Referring to AUTOSAR

As the safety of motor vehicle is taken more and more seriously, the real-time events in the automotive electronics is more important. The control of engine and power train is the core of automotive electronics, and also the domain which demand the real-time quite seriously. This paper proposes a method which can decode the engine position signal. This method is under AUTOSAR frame, based on the MPC5554 micro controller of Freesacler, and carried out by the enhanced time processor (eTPU). This method can decode the crank signal, and coordinating other modules, it can analyze the engine position signal to obtain the angular clock, fulfilling the engine control.
