Development of ECU Based Starting System for Automobiles

Engine start is a very crucial phase in the operation of automotive engines, the starter motor plays a vital role in this short transient period. However, a complete exhaustive model of the combined engine starter system has not appeared to date in open literature. As a typical mechanical and electric device relating to efficiency, safety to passenger car start and process, passenger car starting system based on integrated control method by electronic control unit (ECU). By using Lead acid battery or recent Absorbent Glass Material battery (AGM) how the battery behavior is studied by measuring peak current including cold cranking ampere (CCA).This paper discusses an approach to develop electronic control unit based starting system to reduce the internal resistance of the battery due to overloading, failure of mechanical components of starter motor and pitting of electrical contacts of solenoid switch.
