An Approach to a Standard Engine Management System for 1983 and Beyond

This paper discusses a standard engine management system built around an extension of an existing 16 bit microprocessor architecture. The development program requirements are considered for both hardware and software through vehicle test.

Both digital and analog inputs and outputs are categorized by type. These categories are then used to describe system input and output design for their service.

Finally, future computational requirements are treated along with the architecture necessary for their solution.

The approach described in this paper is based upon the concept that future automotive control requirements can be solved by only slight modifications to a standard control philosophy.
