ACTIVE LIGHTING CONTROL FOR COMMUNICATING A STATE OF AN AUTONOMOUS VEHICLE TO ENTITIES IN A SURROUNDING ENVIRONMENT
First Claim
1. A method comprising:
- accessing sensor data generated by a sensor system of an autonomous vehicle;
determining, based at least in part on the sensor data, a location of the autonomous vehicle within the environment, wherein the location of the autonomous vehicle identifies a position and orientation of the autonomous vehicle within the environment according to a global coordinate system;
calculating, based at least in part on the location of the autonomous vehicle and at least a portion of the sensor data, a trajectory of the autonomous vehicle, wherein the trajectory indicates a planned path associated with navigating the autonomous vehicle between at least a first location and a second location within the environment;
identifying, based at least in part on the sensor data, an object within the environment;
determining a location of the object in the environment, wherein the location of the object identifies a position and orientation of the object within the environment according to the global coordinate system;
determining, based at least in part on the location of the object and the location of the autonomous vehicle, to provide a visual alert;
selecting a light pattern from a plurality of light patterns, wherein a first one of light patterns is associated with a first level of urgency of the visual alert, and a second one of the light patterns is associated with a second level of urgency of the visual alert;
selecting, from a plurality of light emitters of the autonomous vehicle, a light emitter to provide the visual alert; and
causing the light emitter to provide the visual alert, the light emitter emitting light indicative of the light pattern into the environment.

Abstract
Systems, apparatus and methods implemented in algorithms, software, firmware, logic, or circuitry may be configured to process data and sensory input to determine whether an object external to an autonomous vehicle (e.g., another vehicle, a pedestrian, a bicyclist, etc.) may be a potential collision threat to the autonomous vehicle. The autonomous vehicle may include a light emitter positioned external to a surface of the autonomous vehicle and being configured to implement a visual alert by emitting light from the light emitter. Data representing a light pattern may be received by the light emitter and the light emitted by the display may be indicative of the light pattern. The light pattern may be selected to gain the attention of the object (e.g., a pedestrian, a driver of a car, a bicyclists, etc.) in order to avoid the potential collision or to alert the object to the presence of the autonomous vehicle.
