The goal of the SPARC project was to substantially improve traffic safety and efficiency for heavy goods vehicles and passenger vehicles by developing intelligent x-by-wire technologies which included a co-pilot function. Substantial and impressive progress was made on both subsystem and system level, i.e. subsystem integration. A standardised SW/HW platform concept was developed and implemented in tour demonstration vehicles, using similar SW/HW components in an architecture which is scalable from heavy goods vehicles (HGVs) right down to small passenger cars (sPC). 1. Development of an accident-avoiding vehicle using a Decision Control System (DCS), which compensates driver failure probability (driver incapacity, dead man state, etc......). 2. Described and validated clear SW/HW interfaces for automotive redundant control systems to combine results from other related European projects (e.g. PEIT, Prevent, AIDE, etc....). 3. Extended this concept of heavy goods vehicle to full tractor-trailer combination. 4. Validated the scalability of the concept by transferring it from heavy-duty trucks to small passenger cars. Four validator vehicles were built up. 5. Ensured European technology leadership for x-by-wire vehicles. The project successfully demonstrated the integration of several new and important control functions for higher levels of system automation, e.g. secure vector, co-pilot assistance, electromechanical wedge brakes, a fault-tolerant processing architecture, intelligent energy distribution and management. Additionally, a key success of the SPARC project was the development of a scalable platform approach which supports the Integration of X-by-Wire/DCS and active safety systems. The project has developed and demonstrated very promising strategies and paradigms which support the deployment of both: a) full closed-loop DCS technology, and b) x-by-wire subsystems and larger integrated systems. Some of the noteworthy outputs of the SPARC project include: - the Integration of new and innovative hardware and software subsystems e.g. x-by-wire. - a layered open software architecture which incorporates redundancy management. - a number of technology demonstration vehicles based on the ACTROS and SMART platforms. - validation of the concepts within the SPARC project. As part of the final reviewing process several of the concepts and systems developed within the SPARC project were demonstrated. The demonstrations involving the prototype vehicles: Actros (HGV with/without tailor) and the SMART (sPC coupe), and included a split-coefficient of friction braking demonstration, emergency braking, Lane detection and co-pilot Operation. There are no direct policy implications. However, the work on the homologation within the project can be used as base for the homologation in other x-by-wire projects.
