Abstract

Provided herein is a technology for an Autonomous Vehicle Intelligent System (AVIS), which facilitates vehicle operations and control for autonomous driving. The AVIS and related methods provide vehicles with vehicle-specific information for a vehicle to perform driving tasks such as car following, lane changing, and route guidance. The AVIS comprises an onboard unit (OBU), wherein the OBU comprises a communication module communicating with one or more of other autonomous vehicles (AV), a roadside unit (RSU), a cloud platform, and a traffic control center/traffic control unit (TCC/TCU). The AVIS implements one or more of the following functions: sensing, prediction, decision-making, and vehicle control using onboard information and vehicle-specific information received from other AVs, the RSU, the cloud platform, and/or the TCC/TCU.

First claim

We claim:

1. An autonomous vehicle intelligent system (AVIS), comprising:
an onboard unit (OBU),
wherein:
an autonomous vehicle (AV) comprises said AVIS;
the OBU comprises a communication module, wherein the communication module communicates with one or more of: (a) other autonomous vehicles (AVs), (b) a roadside unit (RSU), (c) a cloud platform, or (d) a traffic control center/traffic control unit (TCC/TCU); and receives vehicle-specific information from said one or more of: (a) other AVs, (b) the RSU, (c) the cloud platform, or (d) the TCC/TCU; and
the OBU operates the AV using the vehicle-specific information to provide a sensing function at a microscopic level, a prediction function at a microscopic level, a decision making function at a microscopic level, and/or a control function at a microscopic level; and
the OBU fuses multi-source data collected from vehicle sensors, roadside sensors, and the cloud; and predicts transportation network conditions for the AV at a microscopic level, comprising longitudinal movements and lateral movements.

2. The AVIS of claim 1 , wherein said microscopic level has a time range of 1 to 10 milliseconds.

3. The AVIS of claim 1 , wherein said vehicle-specific information comprises sensing information, prediction information, decision-making information, and control information.

4. The AVIS of claim 1 , wherein the sensing function is performed using sensing data provided by onboard sensors of said AV and said vehicle-specific information, wherein said vehicle-specific information comprises event data, traffic management information, weather information, work zone information, and environmental information.

5. The AVIS of claim 1 , wherein the prediction function is performed using onboard prediction information and said vehicle-specific information, wherein said vehicle-specific information comprises prediction information.

6. The AVIS of claim 1 , wherein the decision-making function is performed using onboard decision-making information and said vehicle-specific information, wherein said vehicle-specific information comprises decision-making information.

7. The AVIS of claim 1 , wherein the control function is performed using onboard control information and said vehicle-specific information, wherein said vehicle-specific information comprises control information.

8. The AVIS of claim 1 , wherein said communication module communicates vehicle static information and/or vehicle dynamic information to the TCC/TCU or to the cloud platform.

9. The AVIS of claim 8 , wherein said vehicle static information comprises vehicle identifier, vehicle size, vehicle type, vehicle software information, and/or vehicle hardware information.

10. The AVIS of claim 8 , wherein said vehicle dynamic information comprises a timestamp, a set of GPS coordinates, a vehicle longitudinal position, a vehicle lateral position, a vehicle speed, a vehicle acceleration, a vehicle origin, and/or a vehicle destination.

11. The AVIS of claim 1 , further comprising a data collection module, wherein the data collection module monitors the operational state of the AV comprising said AVIS.

12. The AVIS of claim 1 , further comprising a vehicle control module, wherein said vehicle control module executes control instructions provided by the OBU or received from said communication module.

13. The AVIS of claim 1 , further comprising an in-vehicle interface.

14. The AVIS of claim 13 , wherein said in-vehicle interface comprises an audio, visual, and/or vibration interface.

15. The AVIS of claim 1 , wherein said AVIS is configured such that when a vehicle control system fails, the OBU takes over in a short time period to stop the vehicle safely.

16. The AVIS of claim 1 , wherein said TCC/TCU or said cloud platform receives data from the AV, generates vehicle-specific information, and/or sends vehicle-specific information to the AV.

17. The AVIS of claim 1 , wherein said TCC/TCU or said cloud platform gathers data, processes information, optimizes a network, and controls traffic.

18. The AVIS of claim 1 , configured to distribute driving tasks and functions for a specific AV among a cloud platform, a TCC/TCU, and a RSU.

19. The AVIS of claim 18 , wherein said functions comprise vehicle-specific sensing functions, vehicle-specific prediction functions, vehicle-specific decision-making functions, and vehicle-specific control functions.
