Abstract
Techniques are disclosed for a priori or real-time intersection trajectory determination of a vehicle, and corresponding messaging of the trajectory determination. Trajectory determination may be based on vehicle static characteristics, dynamic characteristics, and/or intersection geometry. Trajectory messages, which can be communicated using CV2X, may not only indicate the trajectory, but may (optionally) indicate which intersection ingress and egress points the vehicle will block over the course of the traversal of the vehicle along the trajectory.
Claims27
A method of communicating information for traversal of a vehicle through an intersection, the method comprising:
- obtaining information regarding a geometry of the intersection;
- determining a proposed path of the vehicle through the intersection, from a predetermined one of one or more ingress points of the intersection to a predetermined one of one or more egress points of the intersection, based at least in part on:
- one or more characteristics of the vehicle,
- the geometry of the intersection,
- the one or more ingress points, and
- the one or more egress points;
- and
- wirelessly transmitting a message indicative of the proposed path, wherein the message includes ingress and egress blocking information indicative of which of the one or more ingress points and which of the one or more egress points will be blocked by the vehicle during a period of time in which the vehicle traverses through the intersection on the proposed path.
A device for communicating information for traversal of a vehicle through an intersection, the device comprising:
- a wireless communication interface;
- a memory;
- and
- one or more processing units communicatively coupled to the memory and the wireless communication interface, wherein the one or more processing units are configured to:
- obtain information regarding a geometry of the intersection;
- determine a proposed path of the vehicle through the intersection, from a predetermined one of one or more ingress points of the intersection to a predetermined one of one or more egress points of the intersection, based at least in part on:
- one or more characteristics of the vehicle,
- the geometry of the intersection,
- the one or more ingress points, and
- the one or more egress points;
- and
- wirelessly transmit, via the wireless communication interface, a message indicative of the proposed path, wherein the message includes ingress and egress blocking information indicative of which of the one or more ingress points and which of the one or more egress points will be blocked by the vehicle during a period of time in which the vehicle traverses through the intersection on the proposed path.
A device for communicating information for traversal of a vehicle through an intersection, the device comprising:
- means for obtaining information regarding a geometry of the intersection;
- means for determining a proposed path of a vehicle through the intersection, from a predetermined one of one or more ingress points of the intersection to a predetermined one of one or more egress points of the intersection, based at least in part on:
- one or more characteristics of the vehicle,
- the geometry of the intersection,
- the one or more ingress points, and
- the one or more egress points;
- and
- means for wirelessly transmitting a message indicative of the proposed path, wherein the message includes ingress and egress blocking information indicative of which of the one or more ingress points and which of the one or more egress points will be blocked by the vehicle during a period of time in which the vehicle traverses through the intersection on the proposed path.
A non-transitory, computer-readable medium having instructions stored thereby for communicating information for traversal of a vehicle through an intersection, wherein the instructions, when executed by one or more processing units, cause the one or more processing units to:
- obtain information regarding a geometry of the intersection;
- determine a proposed path of the vehicle through the intersection, from a predetermined one of one or more ingress points of the intersection to a predetermined one of one or more egress points of the intersection, based at least in part on:
- one or more characteristics of the vehicle,
- the geometry of the intersection,
- the one or more ingress points, and
- the one or more egress points;
- and
- wirelessly transmit a message indicative of the proposed path, wherein the message includes ingress and egress blocking information indicative of which of the one or more ingress points and which of the one or more egress points will be blocked by the vehicle during a period of time in which the vehicle traverses through the intersection on the proposed path.
