Description

According to claim 1, the invention relates to a positioning device for a navigation system of a motor vehicle, according to claim 9, to an infrastructure facility with a positioning device, and according to claim 14, to a method for navigating a motor vehicle. Today, there is a need to provide a wide range of information to a motor vehicle and/or its user, especially the driver. This is particularly true when the motor vehicle is highly automated, fully automated, or autonomously powered or propelled. In such cases, the driver of such a vehicle is permitted to relinquish control of the vehicle, at least temporarily and/or in certain traffic situations, while the highly automated, fully automated, or autonomous vehicle performs the driving task itself – that is, without any intervention from the human user or driver. For example, the DE 10 2016 217 977 A1 A method for providing traffic surface-related information by means of a machine-readable marking applied to or adjacent to the traffic surface. The machine-readable marking is detected by means of sensors, and information for navigation on the traffic surface or information about the condition of the traffic surface is conveyed in coded form. Furthermore, the DE 10 2015 010 514 B4 A method for determining map information for a map dataset of a navigation environment, whereby objects (such as walls, columns, doors, signs, etc.) are assigned a three-dimensional position. Furthermore, semantic information can be assigned to the respective objects, describing their meaning and/or purpose. The DE 10 2014 002 150 B3 discloses a method for determining the absolute position of a mobile unit. Particularly in connection with an automatic parking system, it is necessary that the vehicle's current position relative to its parking environment is known to the vehicle's navigation system. As described earlier, with an automatic parking system, the driver or user can be relieved of driving tasks related to the system, meaning the vehicle's position is not determined by the driver or user. Instead, a highly accurate map of the parking environment exists, which is stored, for example, in the vehicle's navigation system. Furthermore, the parking environment includes at least one positioning device, which contains a machine-readable data carrier or a multitude of machine-readable data carriers. Each of these data carriers has a unique identifier that can be detected and read by a sensor in the vehicle (for example, a camera sensor, a laser sensor, a lidar sensor, an ultrasonic sensor, etc.). Furthermore, the high-precision map includes the position of each marker or data carrier, allowing the vehicle's sensors (which may include at least one processing unit) to detect the data carriers. This enables the vehicle's own position to be determined relative to its surroundings, particularly through the processing unit. Particularly precise position determination is achieved when the vehicle's sensors simultaneously detect and/or read more than one data carrier. The need to equip the parking environment, or more generally the traffic environment of motor vehicles, with positioning devices or numerous data carriers clashes with the need for particularly space-efficient infrastructure design, especially for parking facilities, creating a conflict of objectives. Currently, the data carriers are particularly large and inflexible, mounted on a support structure (plastic, wood, etc.) within the traffic environment of the motor vehicle. Especially after retrofitting existing parking facilities or parking garages, the data carriers, along with their respective support structures, may protrude in a disadvantageous manner into a driving lane and/or a parking space intended for the motor vehicle. Furthermore, the information that can be conveyed via the marker or data carrier is currently limited to the identifier. The object of the present invention is to provide a particularly efficient and safe navigation system for a motor vehicle in its traffic environment. This problem is solved by a positioning device with the features specified in claim 1, by an infrastructure device with the features specified in claim 9, and by a method comprising the steps specified in claim 14. Features, advantages, and advantageous embodiments of the invention Features, advantages, and advantageous embodiments of the infrastructure device or the method according to the invention are to be regarded as features, advantages, and advantageous embodiments of the infrastructure device according to the invention, and vice versa. Features, advantages, and advantageous embodiments of the infrastructure device according to the invention are to be regarded as features, advantages, and advantageous embodiments of the method according to the invention, and vice versa. According to a first aspect, the invention relates to a positioning device, which can also be referred to as a "marker," for a motor vehicle navigation system.
