An Integration Approach on Powertrain Control System 890762

ABSTRACT

Engine control systems were the precursor of scale automotive electronics systems using microcomputers. Toyota Motor Corporation introduced high - level, total control of the power train by applying system integration through introducing a multi - CPU system to the 1988 MY Toyota Camry.

Integration in the ECU has been promoted to parallel with system integration. By adopting single - chip microcomputers, monolithic ICs, and hybrid ICs all designed and developed for car electronics, and semiconductor barometric pressure sensors for car electron into ECU's. etc. ever - expandable functions can be provided in a smaller and more lightweight ECU package with higher reliability.
