Abstract

Methods for broadcasting or receiving information through a channel which is dedicated for vehicular safety use are provided. And electronic devices are provided. One of the methods includes: an electronic device mounted on a vehicle obtaining lane information of the vehicle, where the lane information indicates on which lane the vehicle is travelling; and broadcasting the lane information of the vehicle through a channel which is dedicated for vehicular safety use. By employing the methods, electronic devices can broadcast their lane information, road information or layer information through a channel which is dedicated for vehicular safety use, which may meet requirements in some vehicular safety applications.

Claims

1. A method for broadcasting information through a channel which is dedicated for vehicular safety use, comprising:

obtaining, with an electronic device mounted on a vehicle, both lane information of the vehicle and layer information of the vehicle, where the lane information indicates on which lane the vehicle is travelling;

broadcasting the lane information of the vehicle through the channel; and

broadcasting the layer information of the vehicle through the channel, where the layer information indicates on which layer of a multi-layered viaduct the vehicle is travelling.

2. The method according to claim 1, further comprising obtaining an image captured by a camera mounted on the vehicle, and obtaining the lane information of the vehicle from the image based on image processing technologies.

3. The method according to claim 1, further comprising broadcasting road information of the vehicle through the channel, where the road information indicates on which road the vehicle is travelling.

4. The method according to claim 1, further comprising determining the layer information of the vehicle based on determining whether the vehicle is driving uphill or downhill based on torque information of the vehicle.

5. The method according to claim 1, wherein the vehicle is a first vehicle, the method further comprising:

receiving on the channel, which is dedicated for vehicular safety use, a message which is broadcasted periodically by a second vehicle;

extracting from the received message lane information which indicates on which lane the second vehicle is travelling; and

determining whether there is risk that the first and second vehicles will hit each other based on the extracted lane information.

6. The method according to claim 5, further comprising:

extracting from the received message road information which indicates on which road the second vehicle is travelling; and

determining whether there is risk that the first and second vehicles will hit each other based on the extracted road and lane information.

7. The method according to claim 5, further comprising:

extracting from the received message layer information which indicates on which layer of the multi-layer viaduct the second vehicle is travelling; and

determining whether there is risk that the first and second vehicles will hit each other based on the extracted layer and lane information.

8. The method of claim 1, further comprising:

receiving a message which contains lane information of a second vehicle through the channel, where the lane information of the second vehicle indicates on which lane the second vehicle is travelling; and

extracting the lane information of the second vehicle from the message.

9. The method of claim 1, further comprising:

receiving a message which contains lane information of a second electronic device through the channel, where the lane information of the second electronic device indicates on which lane the second electronic device is travelling; and

extracting the lane information of the second electronic device from the message.

10. An electronic device mounted on a vehicle, comprising a transmitter and a processing device configured to:

obtain both lane information and layer information of the vehicle, where the lane information indicates on which lane the vehicle is travelling;

control the transmitter to broadcast the lane information of the vehicle through a channel which is dedicated for vehicular safety use; and

control the transmitter to broadcast the layer information of the vehicle through the channel, where the layer information indicates on which layer of a multi-layered viaduct the vehicle is travelling.

11. The electronic device according to claim 10, wherein the processing device is configured to obtain an image captured by a camera mounted on the vehicle, and obtain the lane information of the vehicle from the image based on image processing technologies.

12. The electronic device according to claim 10, wherein the processing device is further configured to broadcast road information of the vehicle through the channel, where the road information indicates on which road the vehicle is travelling.

13. The electronic device according to claim 10, wherein the processing device is further configured to broadcast layer information of the vehicle through the channel, where the layer information indicates on which layer of the multi-layer viaduct the vehicle is travelling.

14. An electronic device mounted on a first vehicle, comprising a receiver and a processing device configured to:

after a message, which is broadcasted periodically by a second vehicle, is received on a channel by the receiver, extract from the received message road information which indicates on which road the second vehicle is travelling, lane information which indicates on which lane the second vehicle is travelling, and layer information which indicates on which layer of a multi-layer viaduct the second vehicle is travelling, the channel being dedicated for vehicular safety use; and

determine whether there is risk that the first and second vehicles will hit each other based on the extracted road information, lane information, and layer information.

15. The electronic device according to claim 14, wherein the processing device is further configured to:

determining that the first vehicle and the second vehicle do not affect each other responsive to the extracted layer information of the second vehicle being different than layer information for the first vehicle, even if both road information and lane information of the first vehicle are the same as the road information and the lane information of the second vehicle.
