Abstract

Autonomous and manually operated vehicles are integrated into a cohesive, interactive environment, with communications to each other and to their surroundings, to improve traffic flow while reducing accidents and other incidents. All vehicles send/receive messages to/from each other, and from infrastructure devices, enabling the vehicles to determine their status, traffic conditions and infrastructure. The vehicles store and operate in accordance with a common set of rules based upon the messages received and other inputs from sensors, databases, and so forth, to avoid obstacles and collisions based upon current and, in some cases, future or predicted behavior. Shared vehicle control interfaces enable the AVs to conform to driving activities that are legal, safe, and allowable on roadways. Such activities enable each AV to drive within safety margins, speed limits, on allowed or legal driving lanes and through allowed turns, intersections, mergers, lane changes, stops/starts, and so forth.

First claim

The invention claimed is:

1. A manually operated vehicle that operates within a transportation system that manages vehicular behavior, including other manually operated vehicles (MVs) and autonomous vehicles (AVs) that share the transportation system, the vehicle comprising:
a manually operated vehicle including a manually operated steering system and drive train requiring an operator to navigate the vehicle from starting points to destinations within an operating environment including roadways, intersections and infrastructure devices;
an electronic controller in communication with first set of sensors, a second set of sensors and at least one wireless communications interface;
wherein the controller uses the first set of sensors to determine the location of the vehicle within the operating environment, and uses the second set of sensors to monitor the environment in the immediate vicinity of the vehicle;
wherein the transportation system maintains and updates a common set of driving rules that are distributed and shared by the vehicle, other MVs, and AVs within the environment; and
wherein the vehicle exchanges messages with the other MVs, AVs, and infrastructure devices within the environment using the wireless communications interface to determine the status of the other vehicles and the infrastructure devices in the vicinity of the vehicle; and
wherein the common set of driving rules are implemented identically on the AVs and the MV to ensure that the operator of the MV adheres to the same basic driving safety rules and regulations as the AVs;
wherein the common set of driving rules includes route priority where the vehicle exchanges messages with other proximal MVs and AVs to determine a higher priority roadway and a lower priority roadway; and
wherein for merging lanes, the vehicle on the lower priority roadway sends a request to AVs and MVs on the higher priority roadway to enter the higher priority roadway and waits to receive an acknowledgement before proceeding.

2. The vehicle of claim 1 , wherein the first set of sensors operative to provide self-location includes one or more of the following:
GPS,
3D point cloud measurements and matching,
inertial measurements, and
wheel or speed measurement.

3. The vehicle of claim 1 , wherein the second set of sensors operative to monitor an environment surrounding the vehicle include one or more of the following:
LADAR,
LIDAR,
RADAR, and
optical, ranging or stereo computer vision.

4. The vehicle of claim 1 , including an electronic controller operative to perform object recognition or image learning in conjunction with a sensor input.

5. The vehicle of claim 1 , wherein the processor is operative to assist an operator with navigating the vehicle based upon information gathered along a path.

6. The vehicle of claim 1 , wherein the common set of driving rules includes one or more of the following:
data associated with stop signs, speed limits, and lane change prohibitions.

7. The vehicle of claim 1 , wherein:
the infrastructure devices include navigation or roadway status servers; and
the processor is operative to assist an operator with navigating the vehicle based upon information received form the navigation or roadway status servers.

8. The vehicle of claim 7 , wherein the information received form the navigation or roadway status servers includes one or more payloads along a path.

9. The vehicle of claim 1 , further including a memory storing road maps that include terrain information.

10. The vehicle of claim 1 , wherein, in accordance with the common driving rules, the processor is operative to assist an operator in avoiding obstacles or road conditions.

11. The vehicle of claim 1 , wherein, in accordance with the common driving rules, the processor is operative to perform enhanced braking and acceleration functions to avoid obstacles and collisions.

12. The vehicle of claim 1 , including a communications interface operative to exchanges messages with one or more pedestrians to execute the route plans in accordance with the common set of driving rules.

13. The vehicle of claim 1 , wherein the communications interface operative to exchanges messages with one or more pedestrians communicates with localization and tagging units carried or worn by pedestrians to inform the vehicle as to the position or movement of the pedestrians.

14. The vehicle of claim 1 , including a communications interface that interacts with localization and messaging tagging units supported on infrastructure devices.

15. The vehicle of claim 1 , including a communications interface that interacts with localization and messaging tagging units supported on at least some of the infrastructure devices.

16. The vehicle of claim 15 , wherein the infrastructure devices include roadways and vehicles.

17. The vehicle of claim 1 , wherein the controller is operative to detect vehicles entering or within an intersection using the sensors and communicate this information to other vehicles entering or within the intersection.

18. The vehicle of claim 1 , wherein the controller is operative to use the communication interface to control or sequence intersection lights or directional light functions to improve traffic flow or avoid collisions.

19. The vehicle of claim 1 , wherein the controller is operative to use the communication interface to relay messages to other vehicles, pedestrians, or moving objects to improve traffic flow or avoid collisions.

20. The vehicle of claim 1 , wherein the controller is operative to generate route plans from starting points to one or more destinations or intermediary points for presentation to an operator of the vehicle.

21. The vehicle of claim 1 , wherein the controller is operative to modify driver-generated vehicle controls based on information associated with paths that dictate vehicle behavior in proximity to locations along the paths.

22. The vehicle of claim 1 , wherein the information from infrastructure devices includes data to or from stop signs, speed limits, lane change prohibitions, or other navigation and roadway status servers modifying driver generated vehicle controls or behaviors.

23. The vehicle of claim 1 , further including active localization and messaging tagging units carried or worn by pedestrians to inform an operator of the vehicle as to the position or movement of the pedestrians; and/or
further including active localization and messaging tagging units supported on roadway or vehicle protected objects to inform an operator of the vehicle as to the position of the objects.

24. The vehicle of claim 1 , wherein the controller is further operative to automatically perform one or more of the following functions:
parking,
trailer coupling and detachment,
refueling, and
vehicle washing or maintenance.

25. The vehicle of claim 1 , including communications with one or more infrastructure devices with sensors operative to detect vehicles entering or within an intersection and communicate this information to other vehicles entering or within the intersection.

26. The vehicle of claim 1 , further including a dash-mounted kit to operate or program the controller.

27. The vehicle of claim 1 , wherein for entering a yield intersection, the vehicle on the lower priority roadway sends a message requesting creation of an entry hole to AVs and MVs on the higher priority roadway and waits fo
