More Information
Summary:A driver assistance system for a motor vehicle has a surroundings sensor and an evaluation unit for evaluating the surroundings sensor data. The evaluation unit receives data from a positioning device. Furthermore, a reduced or limited subset of data taken from a digital roadmap is stored in a non-volatile memory, which is provided to the evaluation unit. The reduced data are selected to include only data relevant for the function(s) of the driver assistance system. Thereby the driver assistance system does not need to be connected for data transmission with a navigation system.
