Towards a new approach in supporting drivers function: specifications of the SASPENCE system

This paper describes the functional specifications of the SASPENCE system, developed inside the homonymous sub-project in the European co-funded Integrated Project PReVENT. SASPENCE (Safe Speed and safe Distance) concept aims at studying, implementing and assessing a new assisting function, which is able to co-operate with the driver in most critical situations, by means of an optimal HMI, suggesting the most appropriate speed and distance to keep, depending on the external and internal scenarios. In this paper the main functions, the operative scenarios and the main system features are described and detailed.
