Research on Blue-tooth Based Vehicular Hand-free System

At a time lots of problems with transportation system are brought by increasing vehicle users and people's lives are under the threaten of traffic accidents, the concept of safe-driving draws more and more attention. The vehicular hand-free system, with its apparent advantages, plays a positive role in safe-driving and is widely applied. Currently, vehicular system has become a necessary part of safe-driving, as a result of significantly improved performance due to the technical standardization as well as the solving of the problem of one-to-one matching between traditional cellphones and hand-free systems. The paper firstly analyzed the voice quality and transferring speed in vehicular system and then proposed certain suggestions on blue-tooth based vehicular hand-free system.
