Description

The invention relates to a method for detecting potential dangers, a control device for carrying out such a method, a motor vehicle with such a control device and a parking lot monitoring device with such a control device. It is well known that freight transport involves covering long distances that cannot be completed in a single day. This inevitably means that trucks must be parked overnight in rest areas, parking lots, and / or along roads in industrial and / or commercial zones. During this time, both the truck drivers and the trucks and their cargo are exposed to various hazards. These hazards include theft, particularly of the cargo, fuel, and / or the truck itself; robbery of the driver; and damage to the truck, especially from loosened wheel nuts, opening of a fifth wheel coupling, and severing of cables and / or hoses. To reduce these and other dangers, various measures and systems are known. In particular, there are guarded parking lots and / or guarded rest areas. The disadvantage of these is that they are subject to charges and the number of parking spaces is limited. Additionally, guarded parking lots and / or guarded rest areas are not always conveniently located along a given route. Furthermore, a mirror replacement system, with an external optical sensor and an internal display, is known for manually checking the vehicle's surroundings. The disadvantage of this is that the driver must still manually check and monitor the vehicle's surroundings and therefore cannot sleep. Additionally, systems for locking devices are known that sound an alarm if the locking device is damaged. The disadvantage of all known measures and systems is that they are expensive and do not cover all risks. The invention is therefore based on the objective of creating a method for detecting potential dangers, a control device for carrying out such a method, a motor vehicle with such a control device and a parking lot monitoring device with such a control device, wherein the aforementioned disadvantages are reduced, preferably do not occur. The problem is solved by providing the present technical teaching, in particular the teaching of the independent claims and of the preferred embodiments disclosed in the dependent claims and the description. The task is solved, in particular, by creating a method for detecting potential hazards in the vicinity of a parked vehicle. This involves connecting the vehicle's communication interface to a communication network. Subsequently, sensor data in the vehicle's vicinity is acquired using at least one sensor. Alternatively, the sensor data in the vehicle's vicinity is acquired by the communication network. Furthermore, the sensor data is made available in the communication network. The sensor data is then at least partially evaluated within the communication network. This evaluation includes checking for at least one hazard in the vehicle's vicinity based on the sensor data and implementing at least one safety measure if at least one hazard is detected.This advantageously improves the security of the vehicle, its cargo, and the safety of its occupants while parked, particularly during extended periods, especially overnight. Furthermore, the monitoring is cost-effective, as existing vehicle sensors can be utilized. Additionally, it prevents costs associated with damage to or theft of the vehicle. Moreover, the computing power required for data analysis is at least partially offloaded to the communication network, enabling even complex analyses to be performed quickly.

Alternatively or additionally, the mobile device, particularly the application, can alert the user to a detected hazard, specifically displaying the hazard.Optionally, a detected hazard is also compared with the position of the mobile device connected to the vehicle, so that a false alarm, which would be generated by a person with this mobile device, is detected before the safety measure is carried out. In particular, the evaluation of sensor data is activated and / or performed based on a time of day and / or ambient brightness. Specifically, evaluation is activated when the ambient brightness falls below a first predetermined brightness threshold. Alternatively or additionally, evaluation is deactivated when the ambient brightness exceeds a second predetermined brightness threshold, where the first and second brightness thresholds are identical or different.
