Dynamic vehicle grid infrastructure to allow vehicles to sense and respond to traffic conditions
First Claim
1. A method for enabling motor vehicles in a dynamic vehicle grid system to sense and respond to traffic conditions comprising the steps of:
- detecting a vehicle event at a first vehicle in a vehicle grid system;
formulating a warning message at the first vehicle in response to the detected vehicle event, by identifying the vehicle event detected; and
creating a message format indicating the detected event and the identity of the vehicle;
broadcasting the formulated warning message to other vehicles in the dynamic vehicle grid;
detecting the warning message at a first receiving vehicle in the dynamic grid;
determining whether the detected warning message is from a first vehicle or a receiving vehicle;
when the determination is that the detected warning message is not from a first vehicle, interpreting the detected warning message at the receiving vehicle and sending the detected warning message to a driver of the receiving vehicle;
formulating a relay message at the receiving vehicle containing information from the warning message detected at the receiver vehicle, the relay message containing a field that identifies a sender of the relay message as a relay message sender and not the first vehicle which sent the original warning message;
relaying the formulated relay message to other vehicles in close proximity to the receiving vehicle that formulated the relay message; and
repeating said relay message formulating step and said message relaying step at receiving vehicles that received the relay message.

Abstract
A dynamic ‘vehicle grid’ system provides the ability for drivers to be automatically warned to the conditions of other vehicles in the vicinity. In this grid system, a motor vehicle would be equipped with a transmitter, receiver, computer and a selection of sensors. Other adjacent vehicles are also contain the same of equipment for transmitting and receiving signals. When the sensors in a vehicle detect a change such as hard braking (rapid deceleration) or very slow speed (blockages), it automatically sends this information via the transmitter over a wireless communication channel to any other receivers in the vicinity.

8. A method for enabling motor vehicles in a dynamic vehicle grid system to sense and respond to traffic conditions comprising the steps of:
-
detecting a vehicle event at a first vehicle in a vehicle grid system; determining whether the detected event is from the first vehicle; interpreting the detected event at the first vehicle; formulating a warning message at the first vehicle in response to the detected vehicle event, by identifying the vehicle event detected; and
creating a message format indicating the detected event, the identity of the vehicle and identifying in a field contained in the message information that identifies a sender of the message as the first vehicle;broadcasting the formulated warning message to other vehicles in the dynamic vehicle grid; detecting the warning message at a first receiving vehicle in the dynamic grid; determining whether the detected warning message is from a first vehicle or a receiving vehicle; when the determination is that the detected warning message is from the first vehicle, interpreting the detected warning message at the receiving vehicle and sending the detected warning message to a driver of the receiving vehicle; formulating a relay message at the receiving vehicle containing information from the warning message detected at the receiver vehicle, the relay message containing a field that identifies a sender of the relay message as the first vehicle which sent the original warning message; relaying the formulated relay message to other vehicles in close proximity to the receiving vehicle that formulated the relay message; and repeating said relay message formulating step and said message relaying step at receiving vehicles that received the relay message.
