Abstract

The invention discloses a method for simulated demonstration of vehicle navigation in a central navigation system, and relates to a traffic control method for transferring navigation instructions to the vehicle. The method comprises the following steps: a demonstrator presses the navigation button of a simulated demonstration navigation terminal to send a navigation request that contains the current location to a navigation center; the demonstrator reports the destination to the navigation center by using radio voice; the navigation center calculates the optimum path, generates information data of a group of landmark point sequences on the path, and sends the information data to the navigation terminal; the navigation terminal extracts the information data of a landmark point according to the sequence of the information data of the group of landmark point sequences and divides the distance between the current location and the landmark point into a plurality of segments, decreases the distance progressively according to timing steps of a timer, and displays the prompt voice information and the videotex navigation information of the landmark point when the distance value is reduced to an initial lead value of the prompt information; when the distance value is zero, the information data of the next landmark point is extracted and the process is repeated till reaching the destination.

Description

technical field

[0001] The invention relates to a traffic control method for road vehicles, in particular to a traffic control method for transmitting navigation instructions to vehicles with satellite positioning and communication equipment. technical background

[0002] At present, the navigation control methods for road vehicles are basically autonomous vehicle navigation methods, that is, the navigation equipment of road vehicles is equipped with electronic navigation maps and positioning devices, and the positioning devices continuously detect the current position of vehicles during driving. , and mark the current position of the vehicle on the displayed electronic navigation map for the driver to use as a reference for travel. The autonomous vehicle navigation method generally requires that the vehicle navigation equipment is equipped with a DVD or other storage devices for storing electronic maps, and at the same time requires that the CPU of the vehicle navigation eq...
