embodiments The invention will be described below with reference to a drawing explained.

there shows:

1 schematically a block diagram of a navigation device with a display unit for performing the method according to the invention.

The one in the only one 1 illustrated navigation device 1 is arranged in particular in a vehicle, not shown, and includes a display unit 1.1 for issuing a route R.

In this case, a non-illustrated vehicle user a desired starting position S, a desired destination Z, a desired departure and / or arrival time and other route options not shown as input information via an input unit 1.2 a control unit 1.3 the navigation device 1 respectively.

The input unit 2 can be z. B. as a microphone, as a conventional keyboard and / or as a touch-sensitive screen, so that the input can be made acoustically and / or manually. In addition, the input unit 1.2 and the output unit 1.1 be designed as a common touch-sensitive screen.

The control unit 1.3 is in particular designed as a conventional control device, for example as a navigation control device, in which the method according to the invention for controlling the display geeinheit 1.1 is deposited as an algorithm.

A receiving unit 1.4 , for example, executed as a GPS receiving unit, receives a current vehicle position POS and also leads this to the control unit 1.3 to. A storage unit 1.5 contains road information, eg. B. in the form of a digital road map K, which is also the control unit 1.3 be supplied. From those of the control unit 1.3 supplied quantities determines this a route R, which in the context of a route guidance by means of the display unit 1.1 is output within a map section KA.

Usually, a scale for displaying the map section KA is set as a function of position information, map data, a vehicle speed and / or time-dependent. According to the invention, the scale is additionally set as a function of static environment information UI _stat and / or dynamic environment information UI _{dyn of} an environment of the vehicle.

The static environment information UI _stat include in particular special destinations, so-called points of interest, which may be located on or next to the route R, and / or additional information about these. The points of interest and the additional information are also in the memory unit 1.5 deposited.

The POIs are in particular interesting addresses and places, which under certain categories, such. As restaurants, hotels, gas stations, ATMs, parking garages or garages are summarized. The points of interest are during route guidance in the means of the display unit 1.1 output map section KA preferably shown as icons. The additional information may include, for example, opening hours, an address, a telephone number or other information about the POIs.

The dynamic environment information UI _dyn include in particular traffic _information , such. As traffic congestion, traffic accidents, road closures and / or wrong-way driver and weather information. Furthermore, other information, which is for the user or users of interest, are outputted as the dynamic environment information can UI _dyn.

The dynamic environment information UI _dyn are next to the current vehicle position POS by means of the receiving unit 1.4 received and the control unit 1.3 fed. By means of the receiving unit 1.4 For this purpose, a continuous check is carried out as to whether there is current dynamic environment information UI _dyn for a planned or a probable route R. In this case, the dynamic environment information UI _{dyn can be received,} for example, based on vehicle-to-vehicle communication, vehicle infrastructure communication, use of a traffic message channel (= TMC) or other known transmission devices and methods, but can also be sent.

By means of the control unit 1.3 According to a further development of the invention, the static environment information UI _stat and the dynamic environment information UI _{dyn are} filtered as a function of preferences of the user, a relevance, an importance and / or a distance from a current vehicle position POS, such that only the environmental information UI _stat and UI _{dyn are} output, which are of interest to the user or users and on the other hand, the environment information UI _stat and UI _{dyn are ordered} according to their importance.

So that the users quickly recognize that current information UI _stat and UI _dyn are present on the current or the probable route R, they are output, for example, by means of a symbol and / or in text form, which / which z. B. is characterized by a striking color or a flashing presentation. In addition, an audible indication may be issued in the presence of environment information UI _stat and UI _dyn . Also, at least to the dynamic environment information UI _dyn warnings, z. As congestion warnings, weather warnings and / or other danger warnings issued so that the driver can customize his driving style. These warnings are also output as symbols, in text form and / or acoustically.

After filtering, the control unit performs 1.3 in addition to the route R, the static and dynamic environment information UI _stat and UI _{dyn of} the display unit 1.1 and sets the scale of the map shown KA in dependence on the environmental information UI _stat and UI _dyn . If z. B. received a new dynamic environment information UI _dyn , the scale is adjusted and adjusted so that the new dynamic environment information UI _dyn in the map shown KA. Both an environment information UI _stat and UI _dyn and several environment information UI _stat and UI _dyn can be displayed simultaneously.

Advantageously, a minimum period of time between the current vehicle position POS and an achievement of an event or location is predetermined, to which the surrounding information UI _stat and UI _{dyn are} output. This gives the driver sufficient time to prepare for the event and / or z. B. adapt his driving style to this.

The scale is set in an advantageous embodiment of the invention such that at least one of the environmental information UI _stat and UI _dyn relevant section of the route R is located in the map shown KA.

In addition, information H is output to the environment information UI _stat and UI _dyn . This may be, for example, instructions for adjusting the driving style. Thus, it is z. B. possible that the driver early on his driving on on the route R before him occurring weather conditions and / or traffic conditions can adapt, so that increases road safety and / or fuel consumption and thus a pollutant emission of the vehicle can be reduced.

According to a development of the method according to the invention, the scale is automatically reset to an initial value as a function of various criteria or manually by a user. The criteria can be, for example, a specific time interval, which can be predetermined by the user in an advantageous manner, directional statements or other conceivable events. Thus, for example, when outputting a directional instruction, which is output in the form of an arrow display and / or acoustically, a scale of the map section KA adapted to one or more environment information UI _stat and UI _{dyn is} reset to an initial value for the duration of the directional statement. After completion of the directional instruction, the scale is then adapted again to the present environment information UI _stat and UI _dyn . A manual resetting of the scale may preferably be carried out by a confirmation of an awareness of the environment information UI _stat and UI _dyn based on the input unit 1.2 respectively.

In summary, an improved information of the users is made possible by the variable setting of the scale of the map section KA and the conspicuous presentation of the environment information UI _stat and UI _dyn . Furthermore, the driver does not need his eyes constantly, but only with a current environment information UI _stat and UI _dyn on the display unit 1.1 so that it is not distracted from the traffic.
