Embodiment Construction

[0033] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. Here, in the description of the drawings, the same reference numerals are assigned to the same or corresponding elements, and overlapping descriptions are omitted.

[0034]In recent years, in order to alleviate traffic congestion, various traffic restriction rules have been implemented in various places. For example, in Beijing, the restricted date of a vehicle is stipulated according to the last digit of the vehicle's license plate number. It is restricted for general vehicles, but not for special vehicles such as taxis, fire trucks, ambulances, and police cars. In addition, in Shanghai, specific vehicles are not allowed to use elevated roads during rush hour (7:30 am to 9:30 am and 16:30 pm to 18:30 pm, Monday to Friday). In addition, vehicles with license plate numbers beginning with Shanghai C are prohibited from entering the city.

Abstract

The invention relates to a vehicle navigation system and a vehicle navigation method. The vehicle navigation system is a vehicle navigation system capable of being communicated with a center server, and comprises a current-position acquiring part for acquiring a current position of a vehicle, a receiving part for receiving the traffic control information coming from the center server, a storage part for pre-storing the vehicle information, and a processing part for comparing the traffic control information and the vehicle information and updating a driving route of a vehicle from the current position to a destination based on the comparing result, and therefore navigation is performed on vehicles.

Description

technical field [0001] The invention relates to a vehicle navigation system and a vehicle navigation method. Background technique [0002] The car navigation system has a function of navigating the vehicle based on map data information, and the like. When navigating the vehicle, various road restriction information must be considered. For a long time, these traffic restriction information have been pre-stored in the storage medium of the car navigation system together with the map data information. restrictions, etc. [0003] In Patent Document 1, it is disclosed that while collecting the identification data displayed on traffic signs or road traffic information display boards, it is stored in the database of the map as traffic restriction information, and when performing navigation, the stored traffic restriction information is referred to. Car navigation system for navigation. [0004] In the prior art, it is effective for displaying temporary stop, no entry, speed lim...
