Description

Driving support method, driving support device and vehicle Technical Field The invention relates to a method for assisting driving and a device for assisting driving and a vehicle having at least one corresponding device. Background Modern vehicles are increasingly equipped with driver assistance functions. Such a driver assistance function is called, for example, an adaptive cruise control function, a lane assistance function, or a travel assistance function. For example, the driver assistance function may assist the driver in driving in the lane by warning signals or even steering interventions through image-based lane marker detection. However, lanes in road traffic are often temporarily altered if the vehicle were to bypass obstacles such as construction sites. Changed lanes typically include sharp turns and lane narrowing, which is why driving in a changed lane requires increased attention from the driver. Since the changed lane is usually marked only by a temporarily applied yellow lane marking, which can be mixed with a white lane marking, the driver assistance function mentioned at the beginning makes the detection of the lane marking more difficult. Therefore, these conditions affect the safety in assisting the driving. A method and a system for lane monitoring of a motor vehicle, a motor vehicle and an infrastructure device are known from US 2012/0 191 271 A1. US 10 665 109 B1 is such a technology and relates to an infrastructure device that determines temporary lane boundaries and transmits them to a vehicle. EP 2 897 B1 relates to a method for operating a driver assistance system designed for at least partially automatic vehicle guidance and to a motor vehicle. DE 10 201 9 106 777 A1 relates to a driving assistance method. Disclosure of Invention The technical problem is to create an auxiliary driving method, an auxiliary driving device and a vehicle for improving the safety of auxiliary driving. The solution to this technical problem results from the subject matter having the features of the independent claims. Further advantageous embodiments of the invention emerge from the dependent claims. An assisted driving method is provided, comprising the following steps: a) Providing at least one piece of information about at least one changed lane, the at least one piece of information having at least one support point along the at least one changed lane, B) At least one lane marker is verified based on the provided at least one information. The at least one message is transmitted from at least one external device to the at least one vehicle, the at least one message being received by the at least one vehicle. In this way, information can be provided immediately before driving on the changed lane. The external device may have at least one microcontroller and/or at least one active communication element. The active communication element may be, for example, a radio transmitter or another communication interface. The external device may be part of a traffic infrastructure. In particular, the external device may be arranged on a construction site vehicle, which for example is parked in the vicinity of the changed lane. Or the external device may be a server that provides information and sends it to the vehicle, for example, over the internet. The vehicle and/or device may include a microcontroller and/or passive communication elements. The passive communication element may be, for example, a radio receiver or another communication interface. To receive information, a vehicle or device may receive information, for example, using passive communication elements. In particular, the provided at least one information may be transmitted locally, with a range of, for example, up to 100 meters, 500 meters, 1000 meters or 2000 meters. According to the invention, at least one lane marking is detected by at least one vehicle when driving on at least one changed lane, and a verification of the at least one detected lane marking is performed by the at least one vehicle by comparing the position of the detected lane marking with the position of the support point, thereby ensuring that the detected lane marking is a lane marking related to the changed lane. An apparatus for assisting driving is also presented, wherein the apparatus is designed to perform one or more steps of the method or the method according to the embodiments described in the present disclosure. The device may be designed as or comprise a microprocessor, for example. A vehicle is also presented comprising at least one apparatus according to an embodiment described in the present disclosure. The vehicle may be designed as a car or truck, for example. The technical effects and advantages explained for the method in the context of the present disclosure are of course also applicable to the device and the vehicle and vice versa. An advantage of this approach is that the information provided can be used to verify the detected lane markings. This improves
