Description

field of technology

The present invention is in the field of driver assistance systems for motor vehicles.

State of the art

When looking for a parking space in their familiar surroundings, drivers of motor vehicles automatically or subconsciously classify parking options with regard to the safety of their parked vehicle. In an environment known to the driver, certain streets or areas are avoided or preferred either generally or depending on the day of the week and the time. Safety in the context of the present invention can mean both traffic safety and safety as protection against theft and vandalism. If a vehicle driver does not have the relevant local knowledge, for example because he is in a city that is unfamiliar to him, he cannot assess the security level of a parking lot or can only do so with little accuracy. With regard to burglary crime, an evaluation of past burglaries and a prognosis derived from this is being tested, at least down to the level of residential areas. However, these systems only use an evaluation of past police data, so they cannot react promptly to local changes.

The present invention describes a method in which a vehicle driver receives support for the selection of a safe parking option for his vehicle. For this purpose, the vehicle has a unit for communication with a backend server. A safety classification for potential parking options is sent to the driver via the backend server, thus helping him to make his choice.

A value is determined on the backend server using a suitable algorithm based on data obtained from a large number of information sources, which value represents the relative safety of the parking spaces. This value can be transmitted to the driver for display or taken into account in an inquiry regarding parking options in an area surrounding a current position. The sources of information and the data they provide are described in more detail below.

One source of data that can be used to determine a value that represents the relative security of a parking space is vehicles that are communicatively connected to the backend server via a corresponding communication unit.

The vehicles can use sensors arranged in or on the vehicle, e.g. For example, acceleration sensors, which are also operated when the vehicle is stationary, can be used to detect unexpected accelerations, such as those that occur when another vehicle touches them, colloquially also referred to as parking bumps. Irrespective of whether this caused damage to the vehicle, this can be taken as an indication of local custom in dealing with property belonging to strangers. In this case, local can describe a district or a city, but also a region of a country or even a country.

A vehicle alarm system is also triggered by on-board sensors. For example, the contact switches on the doors, bonnet and trunk are monitored when the vehicle is stationary. In addition, interior sensors, e.g. infrared sensors, detect movements in the vehicle or smashing windows. Theft by towing can be detected via a position sensor. If an alarm system is triggered, a corresponding data transmission to the backend server can be used to adjust the security classification of the current parking space.

In modern vehicles, camera systems are increasingly being used that enable an all-round view around the vehicle, either through the images from the camera itself or in a virtual representation. For example, four cameras with a 180° field of view are installed, or a correspondingly larger number of cameras, each with a smaller field of view. These camera systems can capture the entire area around the vehicle. By means of appropriate image processing algorithms, an accident, for example, can also be detected. In addition, algorithms for pedestrian detection can also recognize the general volume of people in the vehicle environment; It is also possible to detect vandalism using suitable image processing methods for recognizing the behavior or gestures of people. An image processing method for detecting vandalism can, for example, detect people hitting or kicking. A movement typical of a person's consumption of drinks can also be detected; Depending on the area, this could be an indication of a possibly increased risk, for example if an increase in crimes under the influence of alcohol was registered in the area in the past. Corresponding evaluations of the camera images can be carried out in the vehicle itself, so that only the results have to be transmitted to the backend server. Alternatively, the images can be transmitted to the backend server in order to carry out the evaluation centrally.

A vehicle that is communicatively connected to the backend server via a corresponding communication unit can not only serve as a source of information, but can also receive correspondingly processed security classifications of parking spaces upon request.

Another source of data that can be used to determine a value representing the relative safety of a parking space is data from government agencies and insurers, collected on different occasions for specific regions or locations. This includes, for example, police data on local crime and accident hotspots, which are collected in hazard maps and are also made available to the backend server via a communication interface, eg via an Internet connection. Insurers can also create such hazard maps, e.g. based on damage reports, and send the corresponding data to the backend server.

In all of the above examples it is of course necessary to know the location of the vehicle. This can be ensured by using position information, such as that provided by navigation systems installed in many vehicles or by cell phones coupled to the vehicles.

A vehicle-external system according to the invention for generating and/or updating a first database that makes available a classification of parking spaces that can be called up includes one or more interfaces for receiving data that describe the properties of parking spaces, with the data being recorded by sensors arranged in vehicles and/or or retrieved from a second database. The system also includes a first module for evaluating the data with regard to an accumulation of accidents, damage or break-ins of vehicles and/or the number of people who show relevant behavior in the vicinity of a parking space, and a second module for generating a classification of the parking spaces at least taking into account the evaluation of the data carried out by the first module with regard to an accumulation of accidents, damage to or break-ins of vehicles and/or the number of people who show relevant behavior in the vicinity of a parking lot. Finally, the system comprises one or more interfaces for providing classification information about parking spaces in a vicinity of a geo-position in response to a corresponding request.

An on-board system for collecting data for the classification of parking spaces by a vehicle-external system as described above comprises one or more sensors which detect environmental properties of a parked vehicle and analyze them for events relevant to the safety of the vehicle, the analysis being carried out by a Vehicle-arranged analysis device can be made, the result of which is transmitted to the vehicle-external system and/or the detected environmental properties are transmitted to the vehicle-external system for analysis. One or more interfaces for sending corresponding data are provided for the transmission.

According to the invention, the vehicle-side system can have a navigation system and at least one wireless communication interface, wherein information about an insurance tariff for the vehicle is stored in a memory of the vehicle or can be called up by the vehicle via the at least one wireless communication interface from a corresponding database. In operation, the vehicle navigation system sends a query regarding parking spaces located in a vicinity of a geo-position to the off-board system via the at least one wireless communication interface, and receives a corresponding response. In this aspect, the vehicle navigation system displays a classification for the parking spaces located in the vicinity of the geo-position, or it only displays parking spaces that correspond to a minimum classification stored in the tariff.

4 shows an exemplary schematic message traffic between a vehicle and a backend server of the system according to the invention for the retrievable provision and updating of classification data for parking spaces. A vehicle system first determines its geo-position periodically or continuously, for example by means of a navigation system. In addition, a vehicle system recognizes the driver's intention to park the vehicle, for example based on a corresponding request for parking spaces in the vicinity of the vehicle. Alternatively, the vehicle system can also assume a future parking location of the vehicle as a destination of a route guided by the navigation system. As soon as the intention to park the vehicle and the desired parking location have been determined, a vehicle system sends a corresponding request with the geo-position of the desired parking location to a backend server, which provides the respective security classifications for a large number of parking spaces at a large number of geo-positions. The geo-position can be in coordinates with degrees of latitude and longitude or as place and street names, possibly specified by a house number or the like. The backend server searches the database for known parking options in the vicinity of the geo-position specified in the request and their security ratings, and sends them to the vehicle system.

A radius of the environment can either be preset in the vehicle or selected by the driver, specified in the request or stored in the backend server for a particular vehicle or a particular driver. The vehicle system shows the received parking options and their respective security rating to the driver of the vehicle or transfers the relevant information to a navigation system, which then determines a route to the nearest parking option with a selected or preset minimum security rating and carries out the route accordingly. Alternatively, the backend server only sends information about parking options in the vicinity of the vehicle that corresponds to a selected or preset minimum classification and that is displayed accordingly by the vehicle system or taken into account in route guidance.
