Abstract
A method includes using sensory data produced by at least one onboard sensor of a witness vehicle to predict an imminent collision in an environment of the witness vehicle, the predicted imminent collision involving at least one participant vehicle; and alerting the least one participant vehicle to the predicted imminent collision, wherein the alerting is performed by the witness vehicle and prompts the at least one participant vehicle to perform at least one action to mitigate the predicted imminent collision.
Claims17
A method comprising:
- collecting sensory data produced by an onboard sensor of an autonomous vehicle (AV) and sensory data produced by an onboard sensor of a secondary witness entity;
- processing the collected sensory data to predict an imminent collision in an environment of the AV, the predicted imminent collision involving at least one participant entity;
- providing an alert to the least one participant entity, wherein the alert is provided by the AV and prompts the at least one participant entity to perform at least one mitigating action with regard to the predicted imminent collision, and
- wherein the AV and the secondary witness communicate with one another via a communications network using a standardized messaging protocol;
- determining whether the at least one participant entity is a participant in the communications network if the participant entity is a participant in the communications network, providing the alert using the communications network;
- and
- if the participant entity is a not participant in the communications network, providing the alert using an external collision imminent signal.

A method comprising:
- using sensory data produced by at least one onboard sensor of a witness vehicle to predict an imminent collision in an environment of the witness vehicle, wherein the witness vehicle is a participant in a communications network and the predicted imminent collision involving at least one participant vehicle;
- alerting the least one participant vehicle to the predicted imminent collision, wherein the alerting is performed by the witness vehicle and prompts the at least one participant vehicle to perform at least one action to mitigate the predicted imminent collision;
- and
- determining whether the at least one participant vehicle is a participant in the communications network,
- wherein if the participant vehicle is a participant in the communications network, the alerting is performed using the communications network, and
- wherein if the participant vehicle is not a participant in the communications network, the alerting is performed using an external collision imminent signal.

A vehicle collision detection and response (VCDR) system, the VCDR system comprising:
- a witness vehicle including a sensor suite and a perception module, wherein witness vehicle uses data produced by the sensor suite and the perception module to predict an imminent collision in an environment of the witness vehicle, the predicted imminent collision involving at least one participant vehicle;
- wherein the witness vehicle alerts the least one participant vehicle to the predicted imminent collision to prompt the at least one participant vehicle to perform at least one action to mitigate the predicted imminent collision;
- wherein the witness vehicle is a participant in a communications network, wherein sensory data produced by at least one secondary witness comprising a participant in the communications network is used by the witness vehicle to predict the imminent collision;
- wherein the at least one secondary witness comprises at least one of an autonomous vehicle and a stationary construct;
- and
- wherein if the participant vehicle is a participant in the communications network, the alerting is performed using the communications network and comprises at least one of causing a message to be broadcast on a speaker provided inside the participant vehicle, causing a message to be displayed on a display provided inside the participant vehicle, and causing an action to be taken by an automated driving system of the participant vehicle;
- and wherein if the participant vehicle is a not participant in the communications network, the alerting is performed using an external collision imminent signal comprising at least one of an auditory element produced by the witness vehicle and a visual element produced by the witness vehicle.
