Abstract

The present application discloses a method and a device for assisting the driving of a vehicle and for obtaining the distance between a first and a second distinguishing sign on or at a road. In terms of methods, the first method includes the following steps: identifying the first distinguishing sign on the road on which the vehicle is running or at the road on which the vehicle is driving, and retrieving the first distinguishing sign from the database for the information on the road or on the road. The distance between the second distinguishing marker at , the vehicle is calculated based on the position of the vehicle relative to the first distinguishing marker taking into account the distance between the first distinguishing marker and the second distinguishing marker a relative distance to the second distinguishing mark, and assisting the driving of the vehicle based on the calculated relative distance. The second method comprises the steps of identifying said first and second distinctive markers, calculating a distance between said first and second distinctive markers, and storing the distance between said first and second distinctive markers.

Description

technical field [0001] The present application generally relates to assisting in driving a vehicle based on recognized road markings. The present application also relates to obtaining the distance between two such road markings. Background technique [0002] Driver assistance systems have previously become widely available in larger numbers of vehicles due to mass production and cost reductions in electronic components. One example of such a driver assistance system is a vehicle navigation system. [0003] Vehicle navigation systems deal with the inherent accuracy of position determination of the vehicle in which they are installed. Due to the use of satellite-based positioning systems such as the Global Positioning System (GPS), this accuracy is limited to that of the positioning system. Where GPS is used, position errors are on the order of 10 meters or less. [0004] The vehicle navigation system or its components (eg sensors of a positioning system) can communicate w...
