A Universal Development System for Powertrain Controls Engineers

This paper describes the Universal Development Computer being built to support the development of Electronic Powertrain Control systems at Ford Motor Company. At the heart of Ford's EEC IV system is a custom designed 16 bit 8061 microprocessor. The UDC will provide the tools necessary for advanced concepts implementation prior to inclusion into production prototype designs.

The UDC system is based on a module designed to house a variety of components including custom boards that emulate Ford Motor Company's EEC IV system. A commercially available board set containing a 16 bit 8086 microprocessor is used as the human interface. Non-intrusive control and monitoring of the EEC IV (8061) is maintained, as much as possible, with a fully dual-ported memory between the two microprocessors used in the system.

This paper will highlight the basic features and objectives of the UDC including:

1. 1.
   User friendly, interactive control functions
2. 2.
   Full data acquisition capability
3. 3.
   Easily configured application hardware and software
4. 4.
   Multiple processor (dual 8061's) capability for development of future, high performance EEC modules.
