Autonomous vehicle and center control system
This invention provides a system-oriented and fully-controlled connected automated vehicle highway system for various levels of connected and automated vehicles and highways. The system comprises one or more of: 1) a hierarchical traffic control network of Traffic Control Centers (TCC's), local traffic controller units (TCUs), 2) A RSU (Road Side Unit) network (with integrated functionalities of vehicle sensors, I2V communication to deliver control instructions), 3) OBU (On-Board Unit with sensor and V2I communication units) network embedded in connected and automated vehicles, and 4) wireless communication and security system with local and global connectivity. This system provides a safer, more reliable and more cost-effective solution by redistributing vehicle driving tasks to the hierarchical traffic control network and RSU network.
1. An autonomous vehicle and center control (AVCC) system comprising:
a) a TCC/TCU communication module communicating with a traffic control center/traffic control unit (TCC/TCU) and receiving vehicle-specific control instructions from the TCC/TCU; and
b) an onboard unit (OBU) comprising a vehicle control module controlling a vehicle comprising said AVCC system according to said vehicle-specific control instructions,
wherein said vehicle-specific control instructions comprise instructions for vehicle longitudinal and lateral position; speed; and steering and control.
2. The AVCC system of claim 1 , wherein said vehicle-specific control instructions comprise control instructions for speed, spacing, lane designation, vehicle following, lane changing, and/or route guidance.
3. The AVCC system of claim 1 , wherein said TCC/TCU communication module receives vehicle-specific information comprising weather information, pavement conditions, and/or estimated travel time.
4. The AVCC system of claim 1 , wherein said vehicle transmits data to a TCC/TCU, said data comprising vehicle static information and/or vehicle dynamic information.
5. The AVCC system of claim 4 , wherein said vehicle static information comprises vehicle identifier, vehicle size, vehicle type, vehicle software information, and/or vehicle hardware information.
6. The AVCC system of claim 4 , wherein said vehicle dynamic information comprises a timestamp, GPS coordinates, vehicle longitudinal and lateral position, vehicle speed, and/or vehicle origin/destination information.
7. The AVCC system of claim 1 , further comprising a Roadside Unit (RSU) communication module configured to communicate with an RSU.
8. The AVCC system of claim 1 , further comprising a data collection module monitoring the operational state of the vehicle comprising said AVCC system.
9. The AVCC system of claim 1 , further comprising an in-vehicle interface.
10. The AVCC system of claim 9 , wherein said in-vehicle interface comprises an audio, visual, and/or vibration interface.
11. The AVCC system of claim 1 , wherein said TCC/TCU receives data flow from vehicles, generates vehicle-specific control instructions and information, and/or sends targeted instructions to vehicles.
12. The AVCC system of claim 1 , wherein said TCC/TCU provides data gathering, information processing, network optimization, and traffic control.
13. The AVCC system of claim 1 , wherein said TCC/TCU communication module is configured to communicate wirelessly with one or more TCC/TCU.
14. The AVCC system of claim 1 , further comprising a V2V communication module configured to communicate with a second AVCC system.
15. The AVCC system of claim 1 , configured to distribute driving tasks with a TCC/TCU and RSU network.
16. The AVCC system of claim 1 , wherein said TCC/TCU provides operations and maintenance services for vehicles; and/or provides predictive traffic control.
17. A connected and automated vehicle (CAV) comprising the AVCC system of claim 1 .
18. The CAV of claim 17 , further comprising traffic sensors and/or environment sensors.
19. The CAV of claim 17 , configured to be operational on a portion of available lanes and/or all lanes of a road or highway.
20. The CAV of claim 17 , configured to be controlled by a transportation management system comprising TCC/TCU, a network of RSUs, and a vehicle sub-system.
