THE APPLICATION OF A DATA-DRIVEN PROCESSOR TO AUTOMOTIVE ENGINE CONTROL

Automotive electronics technology has become extremely advanced in the regions of automotive engine control, anti-skid brake control, and ot hers. These control systems require highly advanced control performanc e and high speed microprocessors which can rapidly execute interrupt p rocessing. Automotive engine control systems are now widely utilized i n cars with high speed, high power engines. At present, it is generall y acknowledged that such high performance engine control for the 10,00 0 rpm, 12 cylinder engines requires three or more conventional micropr ocessors. We fabricated an engine control system prototype incorporati ng the data-driven processor under development, which was installed in an actual automobile. In this paper, the characteristics of the engin e control program and simulation results are firstly discussed. Second ly, the structure of the engine control system prototype and the contr ol performance applied to the actual automobile are shown. Finally, fr om the results of software simulation and the installation of the engi ne control system prototype with the data-driven processor, we conclud e that a single chip data-driven microprocessor can control a high spe ed, high power, 10,000 rpm, 12 cylinder automobile engine.
