Vehicle-mounted dynamic navigator

Abstract

The invention relates to the technical field of vehicle navigation, in particular to a vehicle-mounted dynamic navigator. The vehicle-mounted dynamic navigator comprises a map data storage unit for storing map data, a global positioning system for positioning a target vehicle, a vehicle monitoring terminal for monitoring information of road conditions of all paths, a vehicle monitoring server for receiving the road condition information monitored by the vehicle monitoring terminal by a wireless network, calculating the traffic flow and the vehicle running speed of each path according to the road condition information and acquiring traffic congestion information, a central processing unit for reading the map data stored in the map data storage unit, the position of the target vehicle positioned by the global positioning system and the traffic congestion information acquired by calculation of the vehicle monitoring server and processing all the information to select an optimal path, a liquid crystal display screen for displaying the optimal path selected by the central processing unit, and a language unit for reminding driving information of the optimal path by voice.

Description

technical field [0001] The invention relates to the technical field of car navigation, in particular to a car dynamic navigator. Background technique [0002] Vehicle navigation is the product of a high degree of integration of map data, navigation software and car audio. In recent years, vehicle navigation technology is generally based on static map information. However, with the continuous development of society and the continuous development of the economy, the number of cars used for transportation has increased sharply, which has led to an increase in the traffic flow on the road, especially in the morning rush hour and evening rush hour in the city. The phenomenon is very obvious. While the number of cars has increased sharply, the number of traffic accidents has also increased sharply, resulting in more serious traffic jams on the road. The navigation technology based on static map information can only give the optimal route according to the map data, but it cannot ...

AI Technical Summary

Problems solved by technology

The navigation technology based on static map information can only give the optimal route according to the map data, but it cannot use the rapidly changing traffic conditions at all. If there is a high traffic flow or unexpected traffic accidents in the given optimal route, usually If there is a very serious traffic jam, it will cause inconvenience to the car users.
