Vehicle navigation method and system based on cloud server

Abstract

The invention discloses a vehicle navigation method and system based on a cloud server. The method includes the steps that an intelligent mobile terminal receives destination information input by a user and sends a search request to a remote map search server; the map search server receives the search request and searches longitude and latitude coordinate data corresponding to the destination information; the intelligent mobile terminal obtains the longitude and latitude coordinate data from the map search server and sends the longitude and latitude coordinate data to the remote network cloud server through a wireless network; the network cloud server judges whether a vehicle navigation device is on line, if yes, the longitude and latitude coordinate data are sent to the vehicle navigation device through the network cloud server, the vehicle navigation device carries out navigation according to the longitude and latitude coordinate data, and if not, the network cloud server stores the longitude and latitude coordinate data. The vehicle navigation method and system based on the cloud server improve efficiency and speed of destination search, are beneficial to energy saving and environment protection, and reduce cost in using cars.

Description

technical field [0001] The invention relates to the technical field of vehicle navigation, in particular to a method and system for vehicle navigation based on a cloud server. Background technique [0002] With the development of science and technology and the improvement of people's living standards, cars have entered thousands of households, and people's demand for route navigation has also promoted the development of vehicle navigation technology. [0003] The existing vehicle navigation method is to install a navigation device on the car. When the user needs navigation every time, he must temporarily input the destination on the navigation device to search and find. The navigation system starts navigation after the destination determined by the user. [0004] However, in this navigation method, it is necessary to use keyword matching to search, and there are often multiple search results, and the user also needs to select his own destination among multiple search results...

Problems solved by technology

[0004] However, in this navigation method, it is necessary to use keyword matching to search, and there are often multiple search results, and the user also needs to select his own destination among multiple search results before he can navigate. The device is generally fixed inside the vehicle in some way. Due to the fixed angle and the material of the navigation device screen, it is often laborious for users to input keywords to search for destinations, which is not as convenient and fast as operating a mobile phone. Therefore, this method Time-consuming and labor-intensive, low efficiency

[0005] In addition, the average user is used to operating the navigation device after turning on the car after getting in the car. During the time of operating the navigation device, the vehicle is always in the starting state, so it is a waste of energy, which is not conducive to energy saving and environmental protection, but also increases the cost of the car.
