Abstract

Techniques for transmitting vehicle information messages among a plurality of vehicles are disclosed. In an aspect, a transceiver of a vehicle transmits a first set of vehicle information messages over a wireless medium at a first periodic rate, the first set of vehicle information messages including information related to the vehicle. One or more sensors of the vehicle detect an event related to operation of the vehicle. A processor of the vehicle generates a second set of vehicle information messages each including an event flag and information about the event, the event flag indicating that the second set of vehicle information messages is reporting the event. The transceiver of the vehicle transmits a first vehicle safety message of the second set of vehicle information messages over the wireless medium as soon as the first vehicle safety message is generated.

First claim

What is claimed is:

1 . A method for transmitting vehicle information messages among a plurality of vehicles, comprising:
transmitting, by a transceiver of a vehicle of the plurality of vehicles, a first set of vehicle information messages over a wireless medium at a first periodic rate, the first set of vehicle information messages including information related to the vehicle; detecting, by one or more sensors of the vehicle, an event related to operation of the vehicle; generating, by at least one processor of the vehicle, a second set of vehicle information messages each including an event flag and information about the event, the event flag indicating that the second set of vehicle information messages is reporting the event; and transmitting, by the transceiver of the vehicle, a first vehicle information message of the second set of vehicle information messages over the wireless medium as soon as the first vehicle information message is generated.
