ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a navigation system for a land vehicle having a measurement arrangement for supplying position, direction and/or distance data, having a data source arrangement for supplying navigation data, having an input arrangement at least for inputting a destination point, having a control arrangement at least for determining a route, and having at least one display apparatus for outputting navigation instructions.
2. Description of Related Art
The navigation system mentioned above is known from the document Funkschau 20, 1997, pages 70 to 73, “Verkehrsfunk auf Abruf” [Traffic radio on demand]. Digitally coded navigation instructions are supplied from a CD-ROM to a control arrangement which is designed, for example, with a microprocessor. The navigation system uses position data from a GPS system (GPS=Global Positioning System) and the directional data from a gyrocompass to determine position details relating to the vehicle's location. After inputting a destination point, the navigation system guides a driver to this destination point, by audible and visual outputs, after calculating the position of the vehicle and the route to be traveled. In the process, traffic information supplied from an RDS-TMC receiver is also taken into account, in order to indicate, for example, diversion routes. Such a system allows the driver to drive to a destination that he does not know, without any local knowledge and without reading road maps.
SUMMARY OF THE INVENTION
The purposes and advantages of the invention will be set forth in and apparent from the description and drawing that follow, as well as will be learned by practice of the invention. Additional advantages of the invention will be realized and attained by the elements of the navigation system particularly pointed out in the appended claims.
The invention is based on the object of providing a navigation system which allows a driver's local knowledge to be taken into account.
The object is achieved by a navigation system of the type mentioned initially in that, after receiving data from an identification sensor, the control arrangement is provided in order to determine from stored data the driver who is operating the land vehicle, and in that the control arrangement is provided for outputting navigation instructions, matched to the driver, in predetermined regions or on predetermined routes.
According to the invention, the driver is given navigation instructions which are individually matched. In regions or on routes in which or on which the driver has local knowledge it is thus possible to give no navigation instructions, or only few navigation instructions. Setting data for a driver are stored in the control arrangement for specific regions and indicate the navigation instructions that the driver wishes to receive. In contrast to known navigation systems, the invention avoids unnecessary navigation instructions. This improves road safety, since the driver is distracted less.
The driver is determined via an identification sensor. A voice identification device of a voice input system of the input arrangement, an automatic seat adjustment apparatus for the land vehicle or a key identification apparatus for the land vehicle may form such an identification sensor. An identification sensor may likewise be formed by a keypad or a trackball of the input arrangement.
The control arrangement contains a module for driver identification, which module uses data supplied from the identification sensor to determine from stored data the driver who is operating the vehicle and which, after the driver has input a destination, uses stored settings to check whether the driver requires few navigation instructions, or no navigation instructions whatsoever, in specific regions or on a route to the destination. After being input via the input arrangement, the settings for a driver are stored in the control arrangement. The control arrangement can also contain a learning module which stores the routes driven and stores the setting for a frequently used route such that no navigation instructions or few navigation instructions are output for this route.
After receiving specific traffic information via the data source arrangement which relates to the region or the route for which the driver does not want any navigation instructions or wants few navigation instructions, the control arrangement is provided to output precise navigation instructions.
