Description

Parking space monitoring device, vehicle and method Technical Field The invention relates to a parking space monitoring device, a vehicle comprising a parking space monitoring device, and a method for operating a parking space monitoring device. Background Parking guidance systems have been widely used to assist a driver of a vehicle in finding a parking space. In the simplest case, the number of free parking spaces is determined by counting the vehicles coming in and going out. The number of free parking spaces may be provided on a publicly visible display board. A more advanced solution is to transmit information about the number of free parking spaces to an infotainment system in the vehicle. A still further solution is to determine the free parking space in particular by means of a parking space monitoring system by means of fixed sensors or cameras. In this case, a vehicle seeking an empty parking space within a predefined geographical range may be guided to the corresponding empty parking space. The parking space monitoring system may be provided, for example, by a parking lot operator in a parking lot. In this case, the parking space occupation situation is acquired intensively by the parking space monitoring system of the parking lot. Parking space occupancy data may be stored by a parking space monitoring system and provided to vehicles in the parking lot environment. A disadvantage of parking space monitoring systems of the type described at the beginning is that the parking guidance function is limited to the use of the parking space monitored by the parking space monitoring system. Thus, parking spaces without such a parking space monitoring system cannot be considered. As an alternative to centralized parking space monitoring systems, there are decentralized solutions implemented by vehicles communicating with each other. In this case, the participating vehicles detect whether the parking space is free by means of a sensor device and transmit this information to the vehicles in the geographic environment. The participating vehicles may also register and communicate information provided by other participating vehicles. For example, a method for providing free parking spaces is known from DE10 2021, 105, 580 A1. In this disclosure it is described that at least one free parking space is found by a vehicle and information about the at least one free parking space is provided to the vehicle that is finding the parking space using inter-vehicle communication. DE 10 2017 001 600 A1 discloses a method for creating an electronic map containing information about the position of free parking spaces for vehicles. Parking spaces that are not monitored by the parking space monitoring system can be taken into account by the described decentralized scheme. The problem with the decentralized approach is the maintenance of information about the free parking space. Because of the lack of a central node to keep the data, the data must be exchanged in other ways. Known systems require that up-to-date information be communicated via inter-vehicle communication during a communication session between participating vehicles. If the communication session ends, for example when the last one of the participating vehicles has been parked or left the relevant environment, no more up-to-date information is transferred. Thus, the latest information about the free parking space must be re-collected by the participating vehicles in a subsequent communication session. Disclosure of Invention It is an object of the present invention to provide a solution enabling the transfer of information about free parking spaces between communication sessions. This object is achieved by the subject matter of the independent claims. Advantageous developments of the invention are explained in the dependent claims, the following description and the figures. A first aspect of the invention relates to a parking space monitoring device for a vehicle. The parking space monitoring device is configured to provide a parking space occupancy map, wherein the parking space occupancy map includes parking space occupancy data associated with parking spaces in a predetermined geographic area. The parking space monitoring device may be integrated in an infotainment device of the vehicle, for example. The parking space monitoring device may be coupled with a navigation device of the vehicle, for example, in order to assist the driver in finding a free parking space in a predetermined geographical area. The parking space occupation map may include a database in which individual parking spaces in a predetermined geographic area may be listed. In the parking space occupation map, parking space occupation data regarding at least some of the parking spaces may be stored, which may indicate, for example, that the respective parking space is free, occupied, or reserved. In order to efficiently utilize the parking space monitoring device, it is necessary to update the
