NAVIGATION DEVICE WITH ADAPTIVE NAVIGATION INSTRUCTIONS

摘要

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.
