Advantages of the invention

It is considered to be particularly advantageous in the invention that it enables a probability-based provision of navigation destinations. The invention provides a kind of self-learning probabilistic KI (Artificial Intelligence) system based on data mining principles which stores driver and / or user habits and uses these data to identify and provide navigation targets through relevant analysis techniques.

In this way, an input of a navigation destination by the driver can be significantly facilitated because the system based on extensive, concrete data probability-based determined where to go, with redundant information for the driver are largely avoided. A driver often only needs to confirm a frequently approached navigation destination in a comfortable way. Advantageously, the method according to the invention becomes more and more "intelligent" over time, as a result of which the provision of navigation destinations becomes more and more accurate.

The invention will be described in detail below with further features and advantages with reference to two figures. All described or illustrated features, alone or in any combination form the subject matter of the invention, regardless of their summary in the claims or their dependency, as well as regardless of their formulation or representation in the description or in the figures.

Embodiments of the invention

1 shows in a schematic block diagram a system representation of the method according to the invention or the device according to the invention.

The device 100 includes a data acquisition device 10 , which have a communication interface 11 Data to a data processing device 20 transmitted. The Data acquisition device 10 is intended to provide a route, map or other data (date, time, traffic information, calendar data, etc.) to the data processing device 20 to convey. For example, for this purpose, an electronic mobile device (eg a mobile phone, smartphone, etc., not shown) of the driver to the data processing device 20 be connected, which data from an electronic calendar of the mobile device to the data processing device 20 transfers. There is also a database 30 with data on driving or driving habits via the communication interface 11 to the data processing device 20 tethered. For this purpose, the mobile device can be connected, for example by means of a Bluetooth connection to a hands-free system of the motor vehicle to enter additional information about possible / probable destinations.

The communication interface 11 For example, it may be formed as a data bus of a controller (eg, a navigation and infotainment controller, not shown) or as a wireless communication link (cellular connection, WLAN, etc.). For example, it is also conceivable that a server device 31 via mobile communication to the data acquisition device 10 is connected and user data on the mobile connection between the server device 31 and the data acquisition device 10 be replaced. The data processing can therefore be carried out within said control device itself or in a cloud-based computing device, wherein in the case of the cloud-based computing device, data cyclically via the communication interface 11 be transmitted to the cloud-based computing device, wherein results of the data processing via the communication interface 11 to the device 100 be transmitted.

As a result of the data evaluation, an output of a first suggestion list becomes 40 carried out with navigation targets.

Alternatively or in addition to the first suggestion list 40 can also have a second suggestion list 50 may be output with specific traffic information and / or route-related information that may include landmarks, specific user-relevant locations, addresses of people, etc. that take into account individual user habits.

As an advantageous embodiment of the method can also be provided that queries 60 by the data processing device 20 are provided, by means of the data processing device 20 asks a user for additional data that the user can then enter, for example, by voice, by pressing a button, or in any other known manner.

Confirmation of a navigation target proposal by the user becomes a destination selection 70 definitely hit, causing for the device 100 a goal activation is performed. As a result, the motor vehicle becomes a route 80 drove their data to the database 30 be transmitted. In this way, a historical user behavior of the motor vehicle for future applications is stored.

As an advantageous modification, provision may also be made for a number of occupants of the motor vehicle to be determined by means of sensors or seatbelt detectors (not shown). As a result, the system becomes aware, for example, that at a particular time of day, a single user is going to work or, at another time, another person is using the vehicle on another day, which is a likelihood that this trip is a drive to work is reduced.

For an individual identification of the driver of the motor vehicle can also driver identification 90 be provided for the purpose of identifying the driver, for example in the form of a vehicle key, smartphones, etc.

The system according to the invention detects approached navigation destinations and associates these data with driving habits, for example a frequency of a destination, time of day, day of the week, number of occupants in the vehicle, etc. In this way, a list of probable travel destinations can be determined by means of relevant mathematical and statistical analysis methods. The further the driver of a route 80 drives along, the more targets can be on the suggestion lists 40 . 50 to narrow down, as a result of which a probabilistic navigation target selection is provided.

If the system has determined possible targets with a certain probability, it provides them to the driver for selection. This can take the form, for example, of a decreasing probability first and / or second suggestion list 40 . 50 respectively. In addition, the system can determine or narrow down the goal by means of active queries ("Are you just going to ...?").

On the one hand, the destination entry is made considerably easier, and on the other hand, it is also possible to search for relevant traffic data / danger messages even if the route guidance is not activated, in order to offer this to the driver or even make sense if the route guidance is not activated Suggest alternative routes ("Are you on your way to ...? If so, you should follow the following route, as there is currently a traffic jam on your route").

Use of current traffic situation information may also be used to determine if a driver may be driving a known destination on an alternative route.

Due to the fact that typically more than approximately 80% of all journeys are made on known routes, a meaningful combination of historical traffic user data may be used to select future navigation destinations.

2 shows a schematic flow diagram of an embodiment of the method according to the invention.

In a first step S1, position data of the motor vehicle are detected. In a second step S2, a useful characteristic of the motor vehicle is detected.

In a third step S3, at least one probable navigation destination is determined using the position data and the useful characteristic.

Finally, in a fourth step S4, the at least one navigation destination is provided.

In summary, with the present invention, a probabilistic navigation target input is provided by analysis of driving habits. Due to the learning ability of the system through consistent consideration of individual driving habits, an input of navigation targets is significantly simplified. Advantageously, by means of the system according to the invention redundant and incorrectly prioritized navigation targets are largely avoided, so that the driver is very effectively focused gradually on his desired navigation destination. The driver often has to confirm advantageous only a proposed destination, without having to make a lengthy input process. As a result, a security aspect is increased because the driver is no longer distracted by manipulation of the navigation device from the current traffic.

Although the invention has been described in terms of specific embodiments, it is in no way limited thereto. It goes without saying that all mentioned types of data are merely exemplary. A human-machine-interface can be very flexibly adapted to particular requirements (eg with graphical, acoustic, alphanumeric, etc. means), so that the examples described above for the mentioned interface are only exemplary are.

The person skilled in the art will thus suitably modify or combine the features described above without departing from the essence of the invention.
