Embodiment Construction

[0044] In the following, first refer to figure 1 and figure 2 In order to explain the situation in which the method according to the invention is carried out.

[0045] Vehicle 1 is driving on an unreinforced surface. Vehicle 1 can, for example, drive autonomously without driver assistance. The unreinforced surface includes the roadway 2 and laterally next to it in the direction of travel the roadway surroundings 3 . The roadway surroundings 3 limit the roadway 2 . exist figure 1 In the example shown in , the roadway surroundings 3 include a ditch 4 laterally next to the roadway 2 . exist figure 2 In the example case shown in , the roadway 2 is bounded laterally by earth walls 5 and by trees 16 or bridge pylons. When driving on this surface, the wheels of the vehicle 1 form a bearing surface 11 on the roadway 2 .

[0046] As will be explained below, it is possible to identify, with the aid of an embodiment of the method according to the invention and an embodiment of ...

Abstract

The invention relates to a method for determining a quality of a surface in the surroundings of a vehicle (1), wherein three-dimensional surface coordinates of the surface are generated using a sensorassembly (7, 8). The method according to the invention is characterized in that an approximation of the course of the curvature of the surface in at least one direction is obtained on the basis of the surface coordinates, and the surface coordinates are classified in order to characterize the quality of the surface using the course of the curvature and / or vertical distances of the approximation of the course of the curvature from the three-dimensional surface coordinates. The invention further relates to a device for carrying out said method.

Description

technical field [0001] The invention relates to a method for determining properties of surfaces in the surroundings of a vehicle. In the case of the method, the three-dimensional surface coordinates of the surface are generated by means of a sensor device. Furthermore, the invention relates to a device for determining properties of surfaces in the surroundings of a vehicle. The device comprises a sensor device by means of which three-dimensional surface coordinates of the surface can be generated. Background technique [0002] The method and the device according to the invention are particularly relevant for vehicles which drive autonomously or partially autonomously on unreinforced roadways. In this case, it is particularly important to reliably and reliably detect, for example, potholes, slopes, ditches, obstacles and the like. Especially in the autonomous driving of trucks, the properties of the ground to be traversed should be known as precisely as possible. [0003]...
