Intention signaling for an autonomous vehicle
First Claim
Patent Images
1. An intention signaling system for an autonomous vehicle (AV) comprising:
- an output system;
one or more processors; and
one or more memory resources storing instructions that, when executed by the one or more processors, cause the intention signaling system to;
monitor sensor information indicating a situational environment of the AV;
as the AV approaches an intersection, detect an external entity based, at least in part, on the sensor information;
based on detecting the external entity, determine a right-of-way for the intersection between the AV and the external entity;
when the AV has the right-of-way, generate an intention output using the output system to signal an intent of the AV to proceed through the intersection;
when the external entity has the right-of way;
generate a permissive output using the output system to signal acquiescence to the external entity;
monitor the external entity to determine when the external entity complies with the permissive output; and
when the external entity has complied with the permissive output, terminate the permissive output and generate a designated intention output to signal that the AV is to proceed through the intersection;
wherein the executed instructions cause the intention signaling system to generate the permissive output by progressively increasing urgency parameters of the permissive output until the external entity has complied with the permissive output, and wherein the urgency parameters comprise at least one of an audio volume, a brightness, a flash rate, or a scroll rate of the permissive output.

Abstract
An intention signaling system for an autonomous vehicle (AV) can monitor sensor information indicating a situational environment of the AV, and detect an external entity based, at least in part, on the sensor data. The intention signaling system can generate an output to signal one of an intent of the AV or an acquiescence of the AV to the external entity.

11. An autonomous vehicle (AV) comprising:
-
a sensor system to generate sensor data corresponding to a situational environment of the AV; a data processing system to process the sensor data to dynamically identify potential hazards as the AV travels along a current route; an acceleration, steering, and braking system; a control system to utilize the processed sensor data to autonomously control the acceleration, steering, and braking system along the current route; and an intention signaling system comprising; an output system; one or more processors; and one or more memory resources storing instructions that, when executed by the one or more processors, cause the intention signaling system to; monitor the sensor data; as the AV approaches an intersection, detect an external entity based, at least in part, on the sensor data; based on detecting the external entity, determine a right-of-way for the intersection between the AV and the external entity; when the AV has the right-of-way, generate an intention output using the output system to signal an intent of the AV to proceed through the intersection; when the external entity has the right-of way; generate a permissive output using the output system to signal acquiescence to the external entity; monitor the external entity to determine when the external entity complies with the permissive output; and when the external entity has complied with the permissive output, terminate the permissive output and generate a designated intention output to signal that the AV is to proceed through the intersection; wherein the executed instructions cause the intention signaling system to generate the permissive output by progressively increasing urgency parameters of the permissive output until the external entity has complied with the permissive output. - View Dependent Claims (12)

13. A non-transitory computer-readable medium storing intention signaling instructions for an autonomous vehicle (AV), wherein the instructions, when executed by one or more processors, cause the one or more processors to:
-
monitor sensor information indicating a situational environment of the AV; as the AV approaches an intersection, detect an external entity based, at least in part, on the sensor information; based on detecting the external entity, determine a right-of-way for the intersection between the AV and the external entity; when the AV has the right-of-way, generate an intention output using an output system of the AV to signal an intent of the AV to proceed through the intersection; when the external entity has the right-of way; generate a permissive output using the output system to signal acquiescence to the external entity; monitor the external entity to determine when the external entity complies with the permissive output; and when the external entity has complied with the permissive output, terminate the permissive output and generate a designated intention output to signal that the AV is to proceed through the intersection; wherein the executed instructions cause the one or more processors to generate the permissive output by progressively increasing urgency parameters of the permissive output until the external entity has complied with the permissive output. - View Dependent Claims (14)
