Vehicle-mounted system and communication method thereof

Abstract

The invention provides a vehicle-mounted system which comprises a vehicle-mounted system body, wherein the vehicle-mounted system body is provided with a vehicle-mounted system mainboard. The vehicle-mounted system further comprises a wireless multimedia expansion playing device connected with the vehicle-mounted system mainboard, wherein the wireless multimedia expansion playing device is provided with a wireless fidelity (WIFI) module and can be communicated with the vehicle-mounted system mainboard and a mobile device in an environment. The invention further discloses a communication method of the vehicle-mounted system. According to the vehicle-mounted system and the communication method thereof, wireless communication distance is long, communication is very convenient, the structure is simple, and an effect is very good.

Description

technical field [0001] The invention relates to a vehicle, in particular to a vehicle system and a communication method thereof. Background technique [0002] Almost all of the current vehicle multimedia information systems (hereinafter referred to as "vehicle systems") use DVD cores as the carrier, with functions such as AM / FM, external storage MP3, and GPS navigation. With the accelerated integration of the automobile industry and the electronic information industry, automobiles have begun to develop in the direction of electronics and intelligence, and have higher requirements for on-board systems. At present, all vehicle-mounted systems are still in the relatively basic mechanical age, and all existing storage-type playback systems do not use the above-mentioned method. Although with the progress of the times and technology, there are still many problems, such as: [0003] All current vehicle-mounted systems must be installed in the vehicle-mounted system with a tangib...

AI Technical Summary

Problems solved by technology

[0004] Disadvantages: The storage interface often occupies the available space in the car; the extraction does not change when the interface is replaced; the traditional storage playback system is prone to mechanical failures, such as: card machine, jumping pins, data loss, quality distortion, and inconvenience of interface update (SD Card / HDD).

[0006] Disadvantages: The on-board system and external equipment must be connected in series in a wired manner. The existence of AUX wires can easily hinder the driver's actions in the car, and the wires that are too long or too short cannot meet the needs of all passengers in the car (short ones are more convenient for driving. It is not good for the rear seat members; for the elderly, it will affect the driving safety!) Using the AUX cable will also damage the tidy and beautiful interior of the car!

[0008] Disadvantages: Bluetooth transmission bandwidth is limited, it can only be engaged in the transmission of small data, resulting in limited transmission content, at most it can only help the car system play compressed MP3 files, and cannot provide high-quality music sound sources and high-quality digital Video and audio source

[0012] 2. It is necessary to pay a considerable fee to the telecommunications company on a regular basis

[0013] 3. Since the mobile network must be used, the push cannot be realized in areas without network coverage

[0014] 4. The quality of transmission and push is limited by the network speed of the covered area network

[0016] 6. Since the docking requires the assistance of an external network, it is relatively unstable and prone to frequent disconnections!

The vehicle-mounted system cannot carry a large number of removable storage media such as DVDs and perform real-time updates, and the timeliness cannot be guaranteed.
