Problems solved by technology

If, for example, the navigation device tells the driver to "keep left at the next intersection", this may already be annoying for a driver who is very familiar with that intersection
The current navigation device cannot prevent this nuisance cause

Embodiment Construction

[0033] figure 1 A schematic block diagram of an embodiment of a navigation device 10 comprising a processor unit 11 for performing arithmetic operations is shown. Processor unit 11 is configured to communicate with memory units that store instructions and data, such as hard disk 12, read only memory (ROM) 13, electrically erasable programmable read only memory (EEPROM) 14, and random access memory (RAM) 15) Communication. The memory unit may contain map data. This map data can be two-dimensional map data (latitude and longitude), but can also contain a third dimension (height). The map data may further contain additional information, eg information about refueling / gas stations, points of interest. The map data may also contain information about the shape of buildings and objects along the road.

[0034] Processor unit 11 may also be arranged to communicate with one or more input devices (eg, keyboard 16 and mouse 17). Keyboard 16 may, for example, be a virtual keyboard pr...

Abstract

The invention relates to a navigation device wherein navigation instruction are adapted to the driver preferences. The driving behaviour of the driver is recorded (like speed, time to prepare for an exit etc.), and the way he responds to navigation instructions (promptly, or always too late for example). Traffic, weather and time information may be combined with information on the driving behaviour of the driver. This information is examined and used to build up a driver profile. This driver profile is used to adapt future navigation instructions. Alternatively, traffic and weather informat ion may be used to build up route and / or environmental profiles. These profiles can also be used separate form the driver profile to adjust the navigation instruction. The combination of these two techniques, building up a profile (or adapt a pre-defined profile) and adapt the navigation instructions, makes the navigation device a more personal-fit navigation aid. Also, giving the right instructions to a specific driver may contribute to a safer behaviour.

Description

technical field [0001] The invention relates to a navigation device for giving navigation instructions to a user on the basis of a recorded profile. Background technique [0002] Prior art navigation devices based on GPS (Global Positioning System) are well known and widely used as in-vehicle navigation systems. The GPS-based navigation device is a computing device which, in a functional connection with an external (or internal) GPS receiver, is able to determine its global position. Additionally, the computing device is capable of determining a route between a starting address and a destination address, which addresses may be input by a user of the computing device. Typically, the computing means are software enabled for computing a "best" or "best" route between a starting address location and a destination address location from a map database. The "best" or "optimum" route is determined based on predetermined criteria and need not necessarily be the fastest or shortest ...
