Connected automated vehicle highway systems and methods
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 (AV) control system comprising:
a) an RSU communication module communicating with one or more roadside units (RSUs) and receiving vehicle-specific control instructions from said one or more RSUs; and
b) a vehicle control module controlling a vehicle comprising said AV control 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 AV control 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 AV control system of claim 1 wherein said vehicle-specific information comprises weather information, pavement conditions, and/or estimated travel time.
4. The AV control system of claim 1 wherein said RSU communication module transmits data to an RSU, said data comprising vehicle static information and/or vehicle dynamic information.
5. The AV control 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 AV control 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 AV control system of claim 1 further comprising a TCC/TCU communication link configured to communicate with traffic control centers (TCCs) and/or traffic control units (TCUs).
8. The AV control system of claim 1 further comprising a data collection module monitoring the operational state of a vehicle comprising said AV control system.
9. The AV control system of claim 1 further comprising an in-vehicle interface.
10. The AV control system of claim 9 wherein said in-vehicle interface comprises an audio, visual, and/or vibration interface.
11. The AV control system of claim 1 wherein said RSUs receive data flow from vehicles, detect traffic conditions, and/or send targeted instructions to vehicles.
12. The AV control system of claim 1 wherein said RSUs provide data sensing, data processing, control signal delivery, and/or information distribution.
13. The AV control system of claim 1 wherein said RSU communication module is configured to communicate wirelessly with one or more roadside units (RSUs).
14. The AV control system of claim 1 further comprising a V2V communication module configured to communicate with a second AV control system.
15. The AV control system of claim 1 configured to distribute driving tasks with a TCC/TCU and RSU network.
16. A connected and automated vehicle (CAV) comprising the AV control system of claim 1 .
17. The CAV of claim 16 further comprising traffic sensors and/or environment sensors.
18. The CAV of claim 16 configured to be operational on a portion of available lanes and/or all lanes of a road or highway.
19. The CAV of claim 16 configured to be controlled by a transportation management system comprising TCCs/TCUs, a network of RSUs, and a vehicle sub-system.
20. The AV control system of claim 1 , wherein said one or more RSUs are in an RSU network or are spaced along a roadway.
