Description

Method and device for displaying congestion information Technical Field The invention relates to a method and a device for outputting information to a driver of a motor vehicle. Modern motor vehicles have a variety of information output units, such as distance displays, navigation systems, etc. Background It is known from the prior art that information about traffic congestion or traffic congestion warnings can also be output by means of a navigation system. However, motor vehicle operators are often forced to move their vision away from the traffic being driven. This may lead to hazards, especially in the case of traffic congestion, because both drivers approaching traffic congestion and drivers of traffic congestion are at a higher risk of collision with the vehicle in front. From US 2022/0177003 A1 a method for providing a cloud service to a vehicle is known, wherein the local position of the vehicle is taken into account. Traffic conditions on the vehicle travel route may be detected. A transmission device for data transmission is known from JP 2005 117 a 398. JP 2009 025 173A describes a device for a vehicle and a navigation device. JP 2006,267,079A describes a navigation device for guiding a vehicle. Disclosure of Invention It is therefore an object of the present invention to combine such traffic congestion warning with a higher level of safety for the driver of the motor vehicle. According to the invention, this is achieved by the subject matter of the independent patent claims. Advantageous embodiments and further developments are the subject matter of the dependent claims. In the method according to the invention for outputting information, in particular to the driver of a motor vehicle, the geometric and/or geographical position of the motor vehicle is detected and at least one message and/or at least one value is detected, which indicates that a traffic congestion associated with the current or future route of the motor vehicle is characteristic. Furthermore, at least one message and/or value is output (in particular to the driver of the motor vehicle), which characterizes the traffic jam. According to the invention, the information and/or the value is output into the driver's field of view, in which the driver can also observe the road traffic in front of the motor vehicle. The information and/or the value is preferably output into the driver's field of view, which is located directly in front of and/or directly in front of the driver in the direction of travel of the vehicle. It is therefore within the scope of the invention to suggest outputting information to the driver about traffic congestion or about future traffic congestion in such a way that the driver does not have to look away from the road (e.g. on the display of the navigation device). In this way, in particular, a driver looking at the traffic ahead, for example through a windshield, can also preferably detect information about the current or future traffic output to him. In a preferred method, the information is projected onto at least one component of the motor vehicle. In particular, the information is projected onto the windshield of the motor vehicle. The information preferably comprises an information part consisting of numbers, letters and/or graphic elements such as arrows or bars. Particularly preferably, the data representing the traffic congestion are detected by a data receiver of the motor vehicle. It is preferable to select which information for which traffic congestion is to be output to the driver of the motor vehicle. Various traffic congestion situations may occur at a certain point in time, but only one or a few of them are associated with the driver of the motor vehicle. Therefore, the traffic congestion situation in which information is displayed to the driver is preferably selected according to a predetermined criterion. For example, traffic conditions may be displayed based on the current location of travel of the motor vehicle and/or the road. Traffic congestion conditions may also be displayed based on future travel routes of the vehicle. In this way, for a route provided by the navigation system, it is possible to select which traffic congestion or information about which traffic congestion is displayed to the driver. Preferably, at least one value indicative of the local and/or temporal length of the congestion is detected, and preferably a decision is made regarding whether to output information regarding the congestion to the driver taking into account the value. For example, traffic congestion may have only a short traffic congestion distance, in which case no corresponding information is output. The driver may preferably select which traffic congestion should be displayed or which traffic congestion feature values should be displayed. For example, the driver may specify that only traffic congestion with a traffic congestion length exceeding 200m be displayed and/or that only traffic congestion result
