Autonomous vehicle control signal
Methods and systems for communicating between autonomous vehicles are described herein. Such communication may be performed for signaling, collision avoidance, path coordination, and/or autonomous control. An autonomous vehicle may determine an upcoming maneuver for the autonomous vehicle and identify a vehicle signal which is indicative of the upcoming maneuver. Then the autonomous vehicle may present the vehicle signal. After presenting the vehicle signal, the autonomous vehicle may perform the maneuver.
1. A computer-implemented method for controlling vehicle signals in a vehicle having one or more autonomous operation features, comprising:
determining, at one or more processors in a vehicle having one or more autonomous operation features, an upcoming maneuver for the vehicle;
identifying, by the one or more processors, a vehicle signal which is indicative of the upcoming maneuver;
causing, by the one or more processors, the vehicle to present the vehicle signal;
after presenting the vehicle signal, causing, by the one or more processors, the vehicle to perform the maneuver; and
transmitting, by the one or more processors, a communication to one or more other vehicles having one or more autonomous operation features within a communication range of the vehicle, the communication including an indication of the upcoming maneuver.
2. The computer-implemented method of claim 1 , wherein the vehicle signal is presented when the vehicle is unable to transmit communications to other vehicles having one or more autonomous operation features.
3. The computer-implemented method of claim 1 , wherein the vehicle signal is an electromagnetic signal outside of a visible light spectrum, wherein another vehicle having one or more autonomous operation features decodes the electromagnetic signal to identify the upcoming maneuver.
4. The computer-implemented method of claim 1 , wherein the vehicle signal indicates at least one of: braking, turning left or right, turning around, reversing, speeding up, slowing down, changing lanes, merging, another vehicle is travelling too close to the vehicle, moving or swerving to avoid a collision with another vehicle, the vehicle is losing control, or a system failure in at least one of the one or more autonomous operation features.
5. The computer-implemented method of claim 1 , wherein the vehicle signal is presented visually via one or more lights attached to the vehicle, or presented audibly via a vehicle horn or one or more speakers.
6. The computer-implemented method of claim 1 , further comprising:
when an acknowledgment signal is not received at the one or more processors from at least one of the one or more other vehicles in response to transmitting the communication, causing, by the one or more processors, the vehicle to present the vehicle signal to the at least one other vehicle.
7. The computer-implemented method of claim 1 , further comprising:
decoding, by the one or more processors, one or more other vehicle signals received from one or more other vehicles.
8. A computer system configured to control vehicle signals in a vehicle having one or more autonomous operation features, the computer system comprising one or more local or remote processors, transceivers, and/or sensors configured to:
determine, in a vehicle having one or more autonomous operation features, an upcoming maneuver for the vehicle;
identify a vehicle signal which is indicative of the upcoming maneuver;
cause the vehicle to present the vehicle signal;
after presenting the vehicle signal, cause the vehicle to perform the maneuver; and
transmit a communication to one or more other vehicles having one or more autonomous operation features within a communication range of the vehicle, the communication including an indication of the upcoming maneuver.
9. The computer system of claim 8 , wherein the vehicle signal is presented when the vehicle is unable to transmit communications to other vehicles having one or more autonomous operation features.
10. The computer system of claim 8 , wherein the vehicle signal is an electromagnetic signal outside of a visible light spectrum, wherein another vehicle having one or more autonomous operation features decodes the electromagnetic signal to identify the upcoming maneuver.
11. The computer system of claim 8 , wherein the vehicle signal indicates at least one of: braking, turning left or right, turning around, reversing, speeding up, slowing down, changing lanes, merging, another vehicle is travelling too close to the vehicle, moving or swerving to avoid a collision with another vehicle, the vehicle is losing control, or a system failure in at least one of the one or more autonomous operation features.
12. The computer system of claim 8 , wherein the vehicle signal is presented visually via one or more lights attached to the vehicle, or presented audibly via a vehicle horn or one or more speakers.
13. The computer system of claim 8 , wherein the one or more local or remote processors, transceivers, or sensors are further configured to:
when an acknowledgment signal is not received from at least one of the one or more other vehicles in response to transmitting the communication, cause the vehicle to present the vehicle signal to the at least one other vehicle.
14. The computer system of claim 8 , wherein the one or more local or remote processors, transceivers, or sensors are further configured to:
decode one or more other vehicle signals received from one or more other vehicles.
15. A non-transitory computer-readable medium storing thereon a set of instructions that, when executed on one or more processors in a head unit of a vehicle having one or more autonomous operation features, causes the one or more processors to:
determine an upcoming maneuver for the vehicle;
identify a vehicle signal which is indicative of the upcoming maneuver;
cause the vehicle to present the vehicle signal;
after presenting the vehicle signal, cause the vehicle to perform the maneuver; and
transmit a communication to one or more other vehicles having one or more autonomous operation features within a communication range of the vehicle, the communication including an indication of the upcoming maneuver.
16. The non-transitory computer-readable medium of claim 15 , wherein the vehicle signal is presented when the vehicle is unable to transmit communications to other vehicles having one or more autonomous operation features.
17. The non-transitory computer-readable medium of claim 15 , wherein the vehicle signal is an electromagnetic signal outside of a visible light spectrum, wherein another vehicle having one or more autonomous operation features decodes the electromagnetic signal to identify the upcoming maneuver.
18. The non-transitory computer-readable medium of claim 15 , wherein the vehicle signal indicates at least one of: braking, turning left or right, turning around, reversing, speeding up, slowing down, changing lanes, merging, another vehicle is travelling too close to the vehicle, moving or swerving to avoid a collision with another vehicle, the vehicle is losing control, or a system failure in at least one of the one or more autonomous operation features.
19. The non-transitory computer-readable medium of claim 15 , wherein the vehicle signal is presented visually via one or more lights attached to the vehicle, or presented audibly via a vehicle horn or one or more speakers.
20. The non-transitory computer-readable medium of claim 15 , the set of instructions further comprising instructions that causes the one or more processors to:
decode one or more other vehicle signals received from one or more other vehicles.
