Access control method of vehicle-mounted intelligent terminal

Abstract

The invention provides an access control method of a vehicle-mounted intelligent terminal. The access control method comprises the steps as follows: the signal strength of a wireless local area network and a mobile communication network is detected; whether signals of the wireless local area network are superior to those of the mobile communication network is judged according to the detected signal strength; when the signals of the wireless local area network are superior to those of the mobile communication network, a wireless access module selects to establish wireless connection with the wireless local area network; when the signals of the wireless local area network are inferior to those of the mobile communication network, the wireless access module selects to establish wireless connection with the mobile communication network; and the selected wireless local area network or the mobile communication network accesses the internet, and performs data transceiving with a vehicle network service center.

Description

technical field [0001] The present invention relates to a vehicle networking technology, in particular, to an access control method of a vehicle intelligent terminal. Background technique [0002] With the rapid growth of the number of cars in the economy, the problems of traffic congestion, energy consumption and air pollution are becoming more and more serious. This makes even countries with well-developed road facilities have to change from the previous thinking mode of only relying on supply to meet demand. Technologies and methods that are jointly managed by both parties are needed to improve the increasingly acute traffic problems. During this process, the concept of "intelligent transportation system" was gradually formed, and the Internet of Vehicles is an important technical means to realize intelligent transportation. [0003] At present, the basic goal of the development of the Internet of Vehicles is to realize the extraction and effective use of attribute infor...

Problems solved by technology

However, the current vehicle-mounted intelligent terminal is generally connected to the Internet through the mobile communication network. Since vehicle operation is a dynamic process, the vehicle-mounted intelligent terminal may not be able to access the network when the vehicle is running in a place where the signal of the mobile communication network is not good. , resulting in vehicles being unable to obtain Internet of Vehicles services

The current Internet of Vehicles system service reliability is not high
