Abstract

The invention, which belongs to the technical field of the internet of vehicles, provides a communication system of vehicle-mounted electronic equipment and a communication method thereof. According to the method and system, connection with an external wireless communication network is established by using a wireless communication module connected with an SDIO port of vehicle-mounted electronic equipment, thereby enabling the vehicle-mounted electronic equipment to have the wireless communication function. With the WiFi or bluetooth wireless communication module based on the SDIO port, wireless connection and network sharing of the vehicle-mounted electronic equipment and internet communication equipment like a mobile phone or a tablet personal computer and the like are realized. On the basis of the screen mapping technology, a screen of a product like a mobile phone can be mapped to a display platform of the vehicle-mounted electronic equipment and the one-screen interaction function can be realized; and independent connection between the vehicle-mounted electronic equipment and the internet can be realized by using the SDIO-port-based 3G, 4G or 5G wireless communication module.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Vehicles, and in particular relates to a communication system and a communication method for vehicle-mounted electronic equipment. Background technique [0002] In modern life, driving is becoming more and more popular, and all kinds of on-board electronic equipment used in motor vehicles are also showing a trend of high-end and intelligent. [0003] At present, all kinds of vehicle-mounted electronic devices use non-open systems, which cannot be connected to the network to upgrade the system or application software. For example, for a car navigator, if the user wants to update the electronic map, there are generally two ways: one is to go to the after-sales service point to pay or upgrade for free, and the other is to launch the application software by the manufacturer. After the new version is released, After the user downloads from the computer and connects to the car navigator, the up...
