RESEARCH VEHICLE FOR ACTIVE SAFETY
Applications with V-methodology: active suspension
Project leader: Marnix Lannoije
Active safety systems for avoiding accidents are extremely complex electro-mechanical systems. The product developer has a strong interest in managing this complexity in a short development time. This project uses a specific methodology called V-methodology. In this project it is used specifically in the development of a new active suspension system. If this system is coupled to a vision system, the vehicle can see potholes in the road and anticipate them. The active suspension is fitted to and tested on a real vehicle, which can later be used to test other active safety applications. The basic functions of the system have already been fitted and tested. Safety functions and energy management have been integrated and an initial parameter optimisation was carried out on the vehicle.

Goals
The goal of this project is to make V-development methodology proprietary, specifically through the development of active suspension. The approach of judging the forces acting on the wheels and the intelligent management of the suspension lead to improvements in comfort and vehicle dynamics. A vehicle equipped with active suspension will display stable ride characteristics under all conditions. The research has been backed by an innovative rapid prototype, a powerful computer which can calculate complex algorithms. The project includes research into future vehicles' architecture and the use of sensors.
Methodology
In this project, V-methodology is applied at different development stages:
- Analysis of the specifications, system architecture, component specifications, implementation, system integration and test management
- Dangers and risk analysis
- Study of safety integrity and the establishment of safety criteria
-
Efficient optimisation of software functions in a virtual environment
Phases
During a controlled iteration process, the V-model was run through four cycles. At each iteration stage, the system had to fulfil previously defined criteria. At the end, the system was benchmarked against the most advanced system on the market.
