METHOD FOR WIRELESS TRANSMISSION OF INFORMATION BETWEEN IN-VEHICLE COMMUNICATION SYSTEM AND CENTRAL COMPUTER AT OUTSIDE OF VEHICLE

摘要

PROBLEM TO BE SOLVED: To minimize capability of a computer being a requirement of an in-vehicle communication system by attaining transmission and reception of even comparatively long sentence information with an acoustic method through the use of an in-vehicle communication system in an automobile. SOLUTION: In the method where information between an in-vehicle communication system and a central computer at the outside of a vehicle is wireless- transmitted, the in-vehicle communication system is provided with an acoustic output unit to reproduce received information. A central computer at the outside of the vehicle converts information to be sent to the in-vehicle communication system with a sentence form into a phonetic symbol and transmits the information in a form of the phonetic symbol to the in-vehicle communication system. Furthermore, the in-vehicle communication system converts the phonetic symbol into a language, which is outputted via an acoustic output unit.
