Embodiment Construction

[0034] figure 1 A vehicle 100 is shown in which the lane-keeping assist device 101 according to the invention is provided and in which the method for preventing leaving the lane 202 is carried out. The lane-keeping assist device 101 comprises a first sensor 102 which can have, for example, a camera, a stereo camera, a radar sensor, a lidar sensor and / or any combination of these or other sensors. The first sensor 102 detects the vehicle 100 and, in one embodiment, in particular the surroundings of road 200 can be detected.

[0035] The surroundings of the road 200 may include guardrails 206, traffic signs 208, guideposts 212, 220, and buildings 214, 216, 218. Suitable sensors for detecting these objects in the surroundings of the vehicle 100 and / or road 200 are known to those skilled in the art and need not be further described here in a concise sense.

[0036] In addition, the vehicle includes an antenna 103 that can receive signals from multiple satellites. The antenna 103 ...

Abstract

The invention relates to a lane-nondeparture assist device and a method for preventing a vehicle driven by a driver from leaving a lane. The method comprises detecting a surrounding environment of the vehicle by using at least one first sensor, determining a current location of the vehicle based on the surrounding environment of the vehicle detected by the first sensor and stored surrounding environment data, wherein the current location is precise enough to identify the lane of the vehicle, reading a boundary of the lane from a navigation database according to the current location of the vehicle, determining whether the vehicle is at risk of leaving the lane based on the current location and / or speed and / or trajectory of the vehicle and the boundary of the lane read from the navigation database, and performing a kinematic intervention if the vehicle is at risk of leaving the lane.

Description

technical field [0001] The invention relates to a method and an auxiliary device for preventing unintentional departure of a vehicle from a roadway. Background technique [0002] Assistance devices are known in the prior art which assist the driver in the driving task of the vehicle. For example distance aids are known which, when the distances to other vehicles or to standing objects are less than a certain amount, then these distances The assist brakes the vehicle. Lane Keeping Assist warns the driver of the vehicle if the vehicle being operated by that driver unexpectedly leaves the current lane. [0003] Lane keeping assistance systems in the prior art detect with the aid of sensors mounted on the vehicle, such as cameras, whether the vehicle is in or is about to leave the lane or lane unintentionally. The sensors detect the boundaries of the lane. If the lane keeping assist system determines that there is a danger that the vehicle may leave the current lane, the driver...
