Abstract

The invention relates to a method for using vehicle navigation center to navigate online vehicle, wherein said method comprises: storing electric map in navigation center, and storing the information point base one their types, while each point at least comprises the type and position of said point; the navigation center receives the vehicle position from the carrier navigation terminal; the navigation center via the voice communication with vehicle navigation terminal fixes the interested information point type, and searches the nearest information point, as the end point, and uses the start position of vehicle as the starting point of navigation; and the navigation center calculates out the best path from the nearest point to the present vehicle position, and sends said path to the vehicle navigation terminal. The invention can navigate vehicle without target position.

Description

technical field [0001] The invention relates to a car navigation method, in particular to a method for a vehicle navigation center to provide a navigation route to a networked vehicle and a navigation center for realizing the method. Background technique [0002] Car navigation and positioning is a new technology developed on the basis of the global satellite positioning system GPS. Since GPS was converted to civilian use in 1994, its application in car navigation and positioning has developed rapidly. The existing car navigation system generally installs a vehicle navigator on the vehicle, and is equipped with an electronic map at the same time. The vehicle navigator must be able to receive positioning signals from GPS satellites, and at the same time need to have the processing ability of the electronic map and the ability of routing calculation. Therefore, the vehicle navigator is relatively complicated and expensive. [0003] Therefore, people have designed a car networ...
