Method and device for implementing vehicle mounted call

Abstract

The present invention discloses a method to realize vehicle-mounted calls, which arranges a FM transmission module into a mobile phone and sets vehicle mode of the mobile phone. While the mobile phone enters into the vehicle mode, a FM transmission loop is started. An audio loop is switched into the FM transmission loop. The FM transmission module transmits audio signals of specified frequency to a FM broadcasting device. And then, the FM broadcasting device receives the audio signal in a corresponding band and broadcasts the signal through a vehicle-mounted acoustic system. Moreover, the present invention discloses a device to realize the method. The method and the device make it unnecessary for users to directly answer the mobile phone and configure other special vehicle-mounted devices. Furthermore, the method and the device are not restricted by mobile phone manufacturers and need lower cost.

Description

technical field [0001] The invention relates to vehicle-mounted communication technology, in particular to a method and device for realizing vehicle-mounted communication. Background technique [0002] With the rapid development of communication technology, wireless communication technology has also made great progress. As a personal wireless communication terminal, the technology of the mobile phone is increasingly mature, and has become a very popular personal communication device. Because the mobile phone has the advantages of mobile calling, mobile office, and free use, it has a good development prospect and market prospect, and the market competition is becoming increasingly fierce. [0003] Based on the mobility of mobile phones, users can use mobile phones to make calls at any occasion and at any time. However, when the user is driving, there is a lot of inconvenience in using the mobile phone to directly answer or make calls. Driving while making a phone call can ...

AI Technical Summary

Problems solved by technology

However, when the user is driving, it is inconvenient to use the mobile phone to directly answer or make calls

Driving while talking on the phone can easily distract the user and affect the driving safety of the user

But in daily life, many users have to answer or make calls while driving, so the use of mobile phones in the driving process of users is restricted, which will bring great inconvenience to users

[0004] Therefore, there are currently two products on the market that can solve the above problems: one is to equip the mobile phone with a bluetooth earphone. , the use of bluetooth headsets is also restricted

The other is to use special on-board equipment. However, on-board equipment is generally designed and developed by different mobile phone manufacturers for their own models, and some need to be connected to vehicle power supplies, additional devices, etc. Different mobile phones cannot be fully universal
