A Microprocessor Based Vehicular Engine Control System Testbed 770009

A microprocessor based vehicular engine control system testbed has been developed to make possible complex, interactive engine control experiments in the vehicle environment. Designed for flexibility, the on-board vehicle system incorporates two microprocessors, a variety of engine instrumentation, and controls over spark advance, air-fuel ratio, and exhaust gas recirculation. The two microprocessors have been linked to form an efficient computational network with sufficient capacity to implement most, if not all, engine control experiments. Also included in the vehicle are video displays which provide operator control and interaction with experimental engine control systems.
