  • speed limits characterized by special speed limit attributes.
  • the German Highway Code knows speed limits for motorways, which only apply in the event of rain or wet roads. These speed limits thus depend on the respective weather in the area of the corresponding road section.
  • the navigation systems include a signal receiving unit with which position signals can be received. These may in particular be satellite signals from GPS satellites or similar satellite systems. The further processing of position signals, as they are transmitted from the central control of a motor vehicle, such as speed and / or acceleration signals, conceivable. By means of a position determination unit, the navigation system then determines the current position of the vehicle from the position signals.

In this way, data for describing the current weather situation can be read into the navigation system in order to take into account these weather-describing data during subsequent functional processes of the navigation system.

  • a weather-dependent speed limit signal can then be output at the output device of the navigation system.
  • this weather-dependent speed limit can be displayed as a function of the weather by the method according to the invention. This makes it possible, for example, for the normal speed limit to be displayed on dry roads and the rain-specific speed limit for rainy days.

For example, if the speed limit on a road section is limited to 100 km / h on a wet road surface and the navigation system has determined that it is raining by evaluating the weather sensor signals, the driver may exceed the speed limit, for example when driving on the road section at 130 km / h. h, be notified of this exceeding the weather-dependent speed limit. For this purpose, for example, an acoustic speed indication with the words "attention" or "attention speed restriction” can be announced on a loudspeaker. In order to avoid that a speed warning message is output even if the weather-dependent speed limit is very small, a tolerance threshold can additionally be taken into account.
  • This may be an absolute value, for example a tolerance of 10 km / h, or a relative value, for example 10% of the maximum speed of the speed limit. If the tolerance threshold is taken into account, the speed warning is output only if the sum of the current speed and the toe threshold is greater than and / or equal to the maximum speed according to the speed limit.
