However, when driving dynamics variables such as the yaw rate have an offset, there can be a constant or gradual drift between the directly measured yaw rate and the yaw rate calculated with the aid of the navigation system from the curve of the road difference

Embodiment Construction

[0033] figure 1 A vehicle 1 is shown on a two-lane street or a road 2 with two lanes, the road 2 being divided into two traffic lanes by lateral markings 3 and 4 and a central marking 5 . The vehicle is in the first segment 6, at figure 1 In the example of , the first section 6 is realized by a straight road section, and the vehicle moves toward the curve 7 , wherein the vehicle 1 is still a certain distance from the top of the curve, ie, the apex of the curve. After the curve 7, the road 2 transitions into a second section 8, which in the present example is again formed by straight sections.

[0034] figure 2 show figure 1 Together with the situation of vehicle 1 on road 2 before a right curve. The course of the road 2 , which is actually contained in the digital map material, is formed by a first section 6 , a sharp curve 7 and a second section 8 adjoining the curve 7 . The asymptotic algorithm of the course of the street forms a clothoid segment 9 which starts at a po...

Abstract

A method and a device for predicting the future course of a roadway for a transportation vehicle driving on a road, wherein the road has a first section, a bend and a second section, and the bend is arranged between the first and the second section. The method determines an approximated course of a road derived from a digital map material using an original clothoid segment, wherein the clothoid segment has a starting point on the first section, an end point on the second section, and the clothoid segment sweeps over the angle defined by the bend between the first and the second section, and continuously corrects the original clothoid segment by subsequent corrective clothoid segments, wherein the corrective clothoid segments take into account the curvature of the route actually traveled bythe transportation vehicle after the starting point.

Description

technical field [0001] The present invention relates to a method for predicting the future course of a road for vehicles traveling on a road and a device for predicting the future course of the road for vehicles traveling on a road, wherein the road has a first section, a curve and the second section, and the bend is arranged between the first section and the second section, and wherein the device is arranged and designed to perform the method described above. Background technique [0002] At present, digital maps are used in vehicles mainly for navigation purposes in the vehicle's own navigation system, but among them, the digital map data are also used to a greater extent in vehicle guidance by auxiliary systems. Such map data can thus be used, for example, by predictive adaptive cruise control systems in order to adjust the speed before curves or to improve lateral guidance assistance systems with the aid of map data. If the digital map data does not correspond to realit...
