Digital maps have large potential for road safety to enhance or enable preventive and active safety applications by extending driver horizon. As a predictive sensor called ADAS (Advanced Driver Assistance System) Horizon, in-vehicle digital maps are an important source of information providing look-ahead capability for ADAS applications and providing further information for on-board sensors to enhance environment perception. A large range of ADAS applications can benefit from map data, including Adaptive Cruise Control, Adaptive Front Lighting System, Curve Speed Warning, Speed Limit Assistance, Overtaking Assistance, Lane Keeping Assistance and Predictive Powertrain Control. First approaches of map-supported ADAS entering the market are currently using the vehicle's navigation system as the map data source for this preview with a proprietary interface. The advantages of using the navigation system are that it already has a stored record of the map data, and it already performs the tasks of vehicle positioning and map matching. By standardizing access to map data and vehicle position by applications other than navigation, irrespective of the data provider and physical storage format, ADAS applications can focus on performing its main task without having to deal with the complexities of map representation. The map preview is extracted by the ADAS Horizon Provider (AHP) and accessible by all map-supported ADAS applications through the vehicle bus interface. Incremental changes transmitted by the AHP are stored on application side by the ADAS Horizon Reconstructor to build the 1D-track preview delivered to the ADAS application by means of an API. This paper reports on results from the EC project MAPS&ADAS, part of PReVENT Integrated Project, dedicated to the development, test and validation of a standardised interface (ADAS Interface) between ADAS applications and ADAS map data sources for accessing map data regarding vehicle position. The standardisation of the ADAS Interface is a major achievement towards market implementation and industrial perspectives are reflected by the increasing interest of the automotive industry in the ADASIS Forum. The ADASIS Forum, set up in 2002, has to be considered as the User Forum with its 28 Industry Members (vehicle manufacturers, ADAS suppliers, navigation system suppliers and map providers) and aims at supporting and promoting ADAS Interface development and implementation and also exploring new fields of application such as commercial vehicles.
