Core2000 (20644)

The partners PSA Peugeot Citroen and SAGEM of France, SIEMENS of Germany, and SYNDESIS of Greece initiated the collaborative ESPRIT Project "Core2000" in order to enable car manufacturers to address the EURO2000 regulation requirement timely and cost effectively. SAGEM has already developed the EURO2000 and OBD compliant engine management systems for Jaguar and Rover. The new challenge, however, is the necessity of a important cost reduction.

Mainly this will be achieved by minimising hardware cost, in particular by:

• Employing model-based strategies (MBSs) in order to simplify or eliminate several devices and sensors.
• Integrating functionalities and memory devices onto a single advanced microcontroller component.

With its second generation Fuzzy Logic Development Environment (FLDE) for embedded systems, SYNDESIS is contributing to the development of fuzzy logic-based software for a specific engine management control function. In particular FLDE will be extended to address automotive concerns by enhancing its integration in the user's existing development life-cycle and tool-chain, and it will be optimised for the specific microcontroller and the real-time kernel being employed. Thus, fuzzy logic control strategies will be integrated with other software paradigms.

SIEMENS AG is developing a highly integrated microcontroller based on the existing C166 architecture. A variety of derivatives of this microcontroller are already widely used in power train applications. This particular variation will provide the integration of all necessary peripherals and flash memory to achieve best performance at the lowest system cost.

The requirement to reduce fuel consumption as well as emission of pollutants for the very large number of combustion engines in use is all pervasive. The European Commission underpinned this requirement with the regulation EURO2000 which will become applicable in the year 2000 for all passenger cars.This regulation represents an additional challenge for European manufacturers of high volume small and medium size cars for which production costs are extremely sensitive. The Project Core2000 is will deliver an Engine Management System competitively meeting this challenge.

This regulation will require :

• Lower emission levels for all three regulated pollutants: CO, HC and Nox
• On-Board Diagnostic (OBD) control systems to check emissions in order to identify high polution creation.

This regulation represents an additional challenge for European manufacturers of high volume small and medium size cars for which production costs are extremely sensitive. The Project Core2000 delivers an Engine Management System competitively meeting this challenge.

The major results having been achieved are:

• A Digital Core 'C167CS' comprising on-chip Flash memory and innovative A/D-converter
• A particular silicon of the Digital Core to support the calibration
• A Fuzzy Logic comprising CASE tool
• An innovative idle-speed controller based on Fuzzy Logic methodologies
• New model-based strategies for engine control
• A first instance of the ECU compliant with the EURO2000 regulation to evaluate the enhanced strategies for the engine management system
• A test car giving evidence to having achieved the Euro2000 regulation at a sufficient level of driveability as well as the On Board Diagnosis (OBD) requirements all with reasonable margins and an improved cost level
