Abstract

An autonomous vehicle is disclosed. The autonomous vehicle comprises a frame including a support frame; at least one marker supported on the support frame; a marker deployment system including a placement device for locating each of the at least one markers from the support frame at a desired location relative to the vehicle; and an autonomy system that includes a controller, a processor, and a memory device, the memory device stores instructions that when executed by the processor transmit signals to the device causing the device to locate each of the at least one markers at the desired location relative to the autonomous vehicle.

First claim

What is claimed:

1 . An autonomous vehicle comprising:
a frame including a support frame; at least one marker supported by the support frame; a marker deployment system, the marker deployment system including a placement device for locating each of the at least one markers from the support frame to a desired location relative to the vehicle; and an autonomy system comprising a processor and a memory device, the processor programmed to:
receive sensor data from at least one sensor positioned on the autonomous vehicle;
in response to determining that an emergency stop has been performed, determine the desired location relative to the autonomous vehicle for the at least one marker based on the received sensor data; and
warn other vehicles of the emergency stop by transmitting signals to the placement device, the signals causing the placement device to locate each of the at least one markers at the desired location relative to the autonomous vehicle.

2 . The autonomous vehicle of claim 1 wherein the placement device comprises a movable arm that removes at least one of the at least one marker from a support base of the support frame to be located relative to the vehicle.

3 . The autonomous vehicle of claim 2 wherein the moveable arm further comprises a telescoping arm that is extendable and retractable.

4 . The autonomous vehicle of claim 3 wherein the telescoping arm is comprised of a first member and a second member, the second member being movable relative to the first member between a retracted position wherein the second member is nested within the first member and a second position wherein the second member is extended and located outside of the first member.

5 . The autonomous vehicle of claim 3 wherein the movable arm has two ends, a telescoping arm being located at each of the ends.

6 . The autonomous vehicle of claim 5 wherein the arm is movably fixed to the frame between the ends of the autonomous vehicle.

7 . The autonomous vehicle of claim 6 wherein the arm is located proximate to a rear of the vehicle.

8 . The autonomous vehicle of claim 6 wherein the arm is located closer to a front of the vehicle than a rear of the vehicle.

9 . The autonomous vehicle of claim 2 , wherein the movable arm comprises a telescoping arm that is comprised of a plurality of tubes that are extendable and retractable.

10 . The autonomous vehicle of claim 2 wherein the movable arm is rotatable about an axis of rotation and extendable and retractable along a displacement axis.

11 . The autonomous vehicle of claim 2 wherein the movable arm has a free end, a support member being located proximate the free end to support the movable arm when the movable arm is extended.

12 . The autonomous vehicle of claim 11 wherein the support member is a wheel.

13 . The autonomous vehicle of claim 1 wherein the device comprises a motor that moves an arm in response to the signals received from the processor.

14 . The autonomous vehicle of claim 1 wherein the support frame comprises a base, an upper wall and sidewalls, the upper wall, sidewalls and the base defining a chamber, the markers being located on the base and in the chamber.

15 . The autonomous vehicle of claim 14 wherein opposed ends of the support frame are open and accessible by the placement device to remove at least one marker from the chamber.

16 . A system for detecting an emergency stop in an autonomous vehicle and locating at least one marker relative to the autonomous vehicle in response to the emergency stop, the system comprising:
at least one sensor positioned on the autonomous vehicle, the at least one sensor for collecting operation-related data for the autonomous vehicle; a marker deployment system comprising a placement device for locating the at least one marker in a desired location relative to the autonomous vehicle; an autonomy system, the autonomy system including a processor and a memory device, the processor programmed to:
receive, from the at least one sensor, at least one sensor signal representing the operation-related data for the autonomous vehicle;
based on the received at least one sensor signal, determine if an emergency stop has been performed by the autonomous vehicle;
in response to determining that the emergency stop has been performed, determine the desired location relative to the autonomous vehicle for the at least one marker based on the received at least one sensor signal; and
control the device of the marker deployment system to locate the at least one marker to a desired location relative to the vehicle.

17 . The system of claim 16 wherein the placement device comprises a movable arm that removes at least one of the at least one marker from a support base to be located relative to the vehicle.

18 . The system of claim 17 wherein the moveable arm further comprises a telescoping arm that is extendable and retractable.

19 . The system of claim 18 wherein the telescoping arm is comprised of a first member and a second member, the second member being movable relative the first member between a retracted position wherein the second member is nested within the first member and a second position wherein the second member is extended and located outside of the first member.

20 . The of system claim 17 , wherein the movable arm comprises a telescoping arm that is comprised of a plurality of tubes that are extendable and retractable.
