Abstract

Systems for automatically warning at least one nearby vehicle of a potential safety hazard in or near a roadway, including one or more sensors configured to detect a potential safety hazard in or near a roadway; a memory containing computer-readable instructions for generating a message including at least one of a location of the one or more sensors and a location of the potential safety hazard; a processor configured to read the computer-readable instructions from the memory and generate the message; and a transmitter configured to wirelessly transmit the message to at least one nearby vehicle. Systems for coordinating actions of a first vehicle and a second vehicle upon detection of a potential safety hazard in or near a roadway, including in part evaluating whether the actions conflict and, if so, requesting that the first vehicle execute alternative actions for avoiding or mitigating risk of collision. Corresponding methods are disclosed.

First claim

What is claimed is:

1. A system for coordinating actions of a first vehicle and a second vehicle upon detection of a potential safety hazard in or near a roadway, the system comprising:
a first vehicle including:
one or more sensors configured to detect a potential safety hazard in or near a roadway,
a processor configured to:
identify one or more actions to be taken by the first vehicle for avoiding or mitigating a risk of collision with the potential safety hazard, and
generate a message including the information concerning the potential safety hazard and the one or more actions to be taken by the first vehicle, and

a transceiver configured to transmit the message; and

a second vehicle including:
a transceiver configured to receive the message,
a processor configured to:
identify, based on the information concerning the potential safety hazard, one or more actions to be taken by the second vehicle for avoiding or mitigating a risk of collision with the potential safety hazard and the first vehicle,
evaluate whether the one or more actions to be taken by the second vehicle conflict with the one or more actions to be taken by the first vehicle, and
if the actions conflict, generate a second message for transmission to the first vehicle including a request that the processor of the first vehicle execute one or more alternative actions for avoiding or mitigating the risk of collision with the potential safety hazard.
