Embodiment Construction

[0039] The traditional navigation method based on a single satellite positioning system cannot timely and accurately collect traffic information, for example: it cannot accurately perceive the state of traffic flow, or there is no monitoring of traffic flow information at all, but uses historical traffic flow data, let alone give or Predict the traffic flow state for a period of time in the future, so that the existing navigation system only gives an instantaneous navigation path instead of a timely navigation path; it cannot fully perceive the information that road navigation needs to refer to, such as: the structural information of the road (road , whether bridges and tunnel structures are in good condition, whether they are flooded, whether they have collapsed); traffic information of the roads passed (road saturation, service level, number of intersections,); management information of the roads passed (forbidden, single and double No., time limit, height limit, one-way traf...

Abstract

The invention provides a vehicle real-time navigation method and device. The method includes the following steps that a navigation service center receives navigation demand information reported by a vehicle-mounted navigation terminal, wherein the navigation demand information includes destination information; the navigation service center calculates at least one navigation route from the current position to the destination of the vehicle-mounted navigation terminal according to various information relevant to a road and stored in a database; the navigation service center feeds back the calculated and obtained navigation route to the vehicle-mounted navigation terminal. The various information relevant to the road includes the road information showing a road structure, environment information showing a road environment and traffic information showing road traffic rules and traffic states. According to the vehicle real-time navigation method and device, multiple more reasonable navigation routes can be provided for a user to select.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a vehicle real-time navigation method and device. Background technique [0002] At present, in vehicle navigation, the most widely used is a single satellite positioning system (ie: GPS), which locates the current position of the vehicle through satellites, and then calculates One or several navigation paths for the vehicle to reach the destination, and then provide it to the user. [0003] The inventors of the present application found in practice that when calculating the route, the navigation system only considers the current location and destination of the vehicle, but does not consider other relevant information on the road, such as: whether the road is prohibited, whether the road is restricted, and road visibility and other relevant factors, so the navigation path it provides to users may be very unreasonable and unreasonable navigation.
