Portable navigation device for providing navigation information to e.g. automobile driver, has position determination module with couple model for performing complete couple navigation based on received couple data of dynamic vehicle data

摘要

The device has a position determination module (5) connected with a digital data interface and a satellite navigation module for determination of a current position of a vehicle based on determined absolute positions and dynamic data of the vehicle. The position determination module has a couple model for performing a complete couple navigation based on a received complete couple data that is contained in the dynamic vehicle data. Independent claims are also included for the following: (A) a method for optimization of navigation of a vehicle with a portable navigation device (B) a vehicle navigation system with a vehicle having a portable navigation device.
