Description

The invention relates to a method for assisted driving and a device for assisted driving as well as a vehicle with at least one such device. Modern vehicles are increasingly equipped with driver assistance systems. These systems include, for example, adaptive cruise control, lane assist, and travel assist. These systems can, for instance, use image-based detection of lane markings to help the driver stay within their lane by providing warnings or even steering interventions. However, traffic lanes are usually changed temporarily, for example, when a vehicle needs to be guided around an obstacle such as a construction site. The changed lane often includes sharp curves and lane narrowing, which is why driving in the changed lane requires increased attention from the driver. Since the changed lane is usually only marked by temporary yellow lane markings, which can blend in with white lane markings, the detection of lane markings by the aforementioned driver assistance functions is made more difficult. These circumstances therefore compromise safety when using assisted driving. The technical problem is to create a procedure for assisted driving, a device for assisted driving, and a vehicle that improve safety during assisted driving. The solution to the technical problem is provided by the articles with the features of the independent claims. Further advantageous embodiments of the invention are described in the dependent claims. A procedure for assisted driving is proposed, comprising the following steps: Providing at least one piece of information about at least one modified lane, wherein the at least one piece of information has at least one support point along the at least one modified lane, Verify at least one lane marking depending on the provided at least one piece of information, wherein the at least one lane marking is detected when driving on the at least one modified lane by at least one vehicle. A further proposal is for a device for assisted driving, wherein the device is configured to perform one or more steps of the method or a method according to an embodiment described in this disclosure. The device may, for example, be configured as or comprise a microprocessor. Furthermore, a vehicle comprising at least one device according to an embodiment described in this disclosure is proposed. The vehicle can, for example, be designed as a passenger car or a truck. The technical effects and advantages described in this disclosure for the process naturally also apply to the device and the vehicle, and vice versa. The method has the advantage that the detected lane marking can be verified using the provided information. This improves safety during assisted driving. In particular, verification ensures that the detected lane marking is relevant to the changed lane. The altered lane may have a different alignment compared to the original lane. For example, the lane may have a different alignment to guide vehicles around a construction site. The altered lane may be marked, for example, by yellow lane markings on the roadway. The altered lane may have a curved alignment. For example, the altered lane may have an S-shaped curve. The altered lane may have one or more segments, particularly curved segments and/or straight segments. The curved segment may, for example, be a clothoid segment. The provision of this information can be carried out, for example, with the help of an external institution. For instance, the at least one support point can be determined by a person and made available in a database of the external institution. This will be explained in more detail below. The information is provided, in particular, before the at least one vehicle enters the altered lane and/or the at least one lane marking is detected, so that the verification of the detected lane marking can take place immediately upon entering the altered lane. The information can, for example, be part of at least one Decentralized Environment Notification Message (DENM) and/or at least one Infrastructure-to-Vehicle Information (IVI) message. The information can also include the number of altered lanes and/or their arrangement. Furthermore, the information can include at least one characteristic of the at least one altered lane, such as the type of lane markings or road surface damage. This is because the condition of the altered lane also has a significant impact on the safety with which it can be used. The information, in particular the at least one data point, can be referenced to a coordinate system. The reference coordinate system can be a Cartesian coordinate system. The reference coordinate system can be stationary. The reference coordinate system can have a longitudinal axis, a transverse axis, and a vertical axis. The longitudinal axis can be oriented in the direction of travel of the at least one vehicle. The direction in which the longitudinal axis is oriented can also be referred to as the longitudinal direction. The transverse
