A High-Level Language Implementation of an Engine Control Strategy

An engine control program which was originally written in assembly language and which is currently used in production vehicles, has been rewritten using a high-level language specifically designed for automotive control applications. The language and the control strategy are described and the two program implementations are compared in various ways. The high-level language implementation was used to operate a vehicle, and was tested using the software verification process which is used for all production engine control software at Ford Motor Company, Dearborn, Michigan.
