Abstract

A short-distance wireless transmission system for data transmission among electronic devices on a motor vehicle is disclosed to have on-vehicle electronic devices defined with a respective identification code and divided into groups with the electronic devices of the same group connected together by a respective bus that is connected to a respective Bluetooth module so that when one electronic device is sending a data through the connected Bluetooth module, the identification code of the destination device is added to the data for enabling the corresponding Bluetooth module to receive the data accurately and to send the data to the destination electronic device through the respective bus.

Claims

1. A short-distance wireless transmission system for data transmission among electronic devices on a motor vehicle, comprising:

a first electronic device group, said first electronic device group comprising a first short-distance wireless transmitter, at least one first electronic device, and a first connection line electrically connecting said first short-distance wireless transmitter to said at least one first electronic device, said at least one first electronic device each being defined to have a respective first identification code; and

a second electronic device group, said second electronic device group comprising a second short-distance wireless receiver, at least one second electronic device, and a second connection line electrically connecting said second short-distance wireless receiver to said at least one second electronic device, said at least one second electronic device each being defined to have a respective second identification code;

wherein said at least one first electronic device each is adapted to send a first transmission data to said first short-distance wireless transmitter through said first connection line, for enabling said first short-distance wireless transmitter to send out said first transmission data wirelessly, said first transmission data comprising at least one first destination code therein;

wherein said second short-distance wireless receiver is adapted to receive said first transmission data wirelessly and then to send said received first transmission data through said second connection line to at least one corresponding second electronic device of which the respective second identification code conformed to the at least one first destination code of said received first transmission data.

2. The short-distance wireless transmission system for data transmission among electronic devices on a motor vehicle as claimed in claim 1, wherein said second electronic device group further comprises a second short-distance wireless transmitter electrically connected to said at least one second electronic device through said second connection line;

said first electronic device group further comprises a first short-distance wireless receiver electrically connected to said at least one first electronic device through said first connection line;

wherein said at least one second electronic device each is adapted to send a second transmission data to said second short-distance wireless transmitter through said second connection line, for enabling said second short-distance wireless transmitter to send out said second transmission data wirelessly, said second transmission data comprising at least one second destination code therein;

wherein said first short-distance wireless receiver is adapted to receive said second transmission data wirelessly and then to send said received second transmission data through said first connection line to at least one corresponding first electronic device of which the respective first identification code conformed to the at least one second destination code of said received second transmission data.

3. The short-distance wireless transmission system for data transmission among electronic devices on a motor vehicle as claimed in claim 1, further comprising at least one third electronic device group, said at least one third electronic device group each comprising a third short-distance wireless receiver, at least one third electronic device, and a third connection line electrically connecting said third short-distance wireless receiver to said at least one third electronic device, said at least one third electronic device being defined to have a respective third identification code;

Wherein said at least one first electronic device each is adapted to send a third transmission data to said first short-distance wireless transmitter through said first connection line, for enabling said first short-distance wireless transmitter to send out said third transmission data wirelessly, said third transmission data comprising at least one third destination code therein;

Wherein said third short-distance wireless receiver is adapted to receive said third transmission data wirelessly and then to send said received third transmission data through said third connection line to at least one corresponding third electronic device of which the respective third identification code conformed to the at least one third destination code of said received third transmission data.

4. The short-distance wireless transmission system for data transmission among electronic devices on a motor vehicle as claimed in claim 1, further comprising at least one third electronic device group, said at least one third electronic device group each comprising a third short-distance wireless transmitter, at least one third electronic device, and a third connection line electrically connecting said third short-distance wireless transmitter to said at least one third electronic device;

Wherein said at least one third electronic device each is adapted to send a third transmission data to said third short-distance wireless transmitter through said third connection line, for enabling said third short-distance wireless transmitter to send out said third transmission data wirelessly, said third transmission data comprising at least one third destination code therein;

Wherein said second short-distance wireless receiver is adapted to receive said third transmission data wirelessly and then to send said received third transmission data through said second connection line to at least one corresponding second electronic device of which the respective second identification code conformed to the at least one third destination code of said received third transmission data.

5. The short-distance wireless transmission system for data transmission among electronic devices on a motor vehicle as claimed in claim 1, wherein said first short-distance wireless transmitter and said second short-distance wireless receiver are respectively formed of a bluetooth module.

6. The short-distance wireless transmission system for data transmission among electronic devices on a motor vehicle as claimed in claim 1, wherein said first connection line and said second connection line are respectively formed of a Controller Area Network (CAN) Bus.
