Abstract

The aspects disclosed herein generally provide a method and a system of real-time data monitoring for a vehicle. The method comprises packaging monitoring data into one or more physical Automotive Audio Bus (A2B) channels according to a data package protocol; transferring the packaged monitoring data via a A2B bus; and unpackaging the transferred data and displaying the unpackaged monitoring data.

First claim

What is claimed is:

1. A method of real-time data monitoring for a vehicle, comprising:
packaging monitoring data into one or more physical Automotive Audio Bus (A2B) channels according to a data package protocol;
transferring the packaged monitoring data via an A2B bus; and
unpackaging the transferred packaged monitoring data and displaying the unpackaged monitoring data,
wherein packaging the monitoring data further comprising:
calculating a first number value of total data channels for the monitoring data;
calculating a second number value of consumed data channels for the monitoring data based on one physical A2B channel;
comparing the first number value and the second number value; and
packaging the monitoring data into one or more physical A2B channels based on the comparison.

2. The method of claim 1 , wherein the data package protocol is configured to form a data frame including one synchronization data unit, at least one information data unit and at least one monitoring data unit for one physical A2B channel.

3. The method of claim 2 , wherein
the synchronization data unit is filled with a value for synchronizing the monitoring data in one physical A2B data channel;
the at least one information data unit includes four sub-units which are respectively filled with four values, each value represents one of an identification, a signal type, a sampling rate and a number of data channels for the monitoring data; and
the at least one monitoring data unit is filled with the monitoring data associated with the at least one information data unit.

4. The method of claim 1 , further comprises:
packaging the monitoring data into one physical A2B channel in response to the first number value being equal to or larger than the second number value.

5. The method of claim 1 , further comprises:
packaging the monitoring data into more than one physical A2B channel in response to the first number value being less than the second number value.

6. The method of claim 1 , wherein the calculating the first number value of total data channels for monitoring data includes calculating the first number value of total data channels based on a sampling rate of the monitoring data and on an A2B channel sampling rate.

7. The method of claim 1 , wherein the calculating the second number value of consumed data channels includes calculating the second number value of consumed data channels based on a number of at least one information data unit for one physical A2B channel, a number of signal types, and a total number of signals for monitoring data.

8. The method of claim 1 , wherein the unpackaging the transferred data includes extracting information from at least one information data unit of the packaged monitoring data to obtain a signal type, a sampling rate, and a number of data channels for monitoring data.

9. A system of real-time data monitoring for a vehicle, comprising:
an amplifier configured to package monitoring data into one or more physical Automotive Audio Bus (A2B) channels according to a data package protocol, and transfer the packaged monitoring data via a A2B bus;
a Universal Serial Bus (USB) to A2B Box configured to receive the packaged monitoring data via a A2B bus and transfer the packaged monitoring data; and
a monitoring device configured to receive the packaged monitoring data from the USB-to-A2B Box, unpackage the transferred packaged monitoring data according to the data package protocol and display the unpackaged monitoring data,
wherein the amplifier is further configured to:
calculate a first number value of total data channels for the monitoring data;
calculate a second number value of consumed data channels for the monitoring data based on one physical A2B channel;
compare the first number value and the second number value; and
based on the comparison result, package the monitoring data into one or more physical A2B channels.

10. The system of claim 9 , wherein the data package protocol is configured to form a data frame including one synchronization data unit, at least one information data unit, and at least one monitoring data unit for one physical A2B channel.

11. The system of claim 10 , wherein
the synchronization data unit is filled with a value for synchronizing the monitoring data in one physical A2B data channel;
the information data unit includes four sub-units which are respectively filled with four values, each represents one of an identification, a signal type, a sampling rate and a number of data channels for the monitoring data; and
the monitoring data unit is filled with the monitoring data associated with the information data unit.

12. The system of claim 9 , wherein the amplifier is further configured to:
package the monitoring data into one physical A2B channel in response to the first number value being equal to or larger than the second number value.

13. The system of claim 9 , wherein the amplifier is further configured to:
package the monitoring data into more than one physical A2B channel in response to the first number value being less than the second number value.

14. The system of claim 9 , wherein the amplifier is further configured to calculate a first number value of total data channels based on a sampling rate of the monitoring data and on a sampling rate of the one physical A2B channel.

15. The system of claim 9 , wherein the amplifier is further configured to calculate a second number value of consumed data channels based a number of the information data unit for one physical A2B channel, a number of signal types, and a total number of signals for monitoring data.

16. The system of claim 10 , wherein the monitoring device is further configured to extract information from the at least one information data unit of the packaged data to obtain a signal type, a sampling rate and a number of data channels for monitoring data.

17. A non-transitory computer-readable storage medium including instructions that, when executed by one or more processors, perform real-time data monitoring for a vehicle, the computer-readable storage medium comprising instructions for:
packaging monitoring data into one or more physical Automotive Audio Bus (A2B) channels according to a data package protocol;
transferring the packaged monitoring data via an A2B bus;
unpackaging the transferred packaged monitoring data and displaying the unpackaged monitoring data;
calculating a first number value of total data channels for the monitoring data;
calculating a second number value of consumed data channels for the monitoring data based on one physical A2B channel;
comparing the first number value and the second number value; and
based on the comparison result, packaging the monitoring data into one or more physical A2B channels.

18. The computer-readable storage medium of claim 17 , further comprising instructions for forming, via the data package protocol, a data frame including one synchronization data unit, at least one information data unit and at least one monitoring data unit for one physical A2B channel.

19. A method of real-time data monitoring for a vehicle, comprising:
packaging monitoring data into one or more physical Automotive Audio Bus (A2B) channels according to a data package protocol;
transferring the packaged monitoring data via an A2B bus; and
unpackaging the transferred packaged monitoring data and displaying the unpackaged monitoring data,
