Inter-vehicle drowsy driver advisory system
First Claim
1. A driver advisory system for use in a host vehicle and for transmitting to drivers of other vehicles information regarding the status of a driver of the host vehicle, said driver advisory system comprising:
- a sensor monitoring a physical condition of the driver of the host vehicle, said sensor providing an output quantifying said physical condition of the driver of the host vehicle;
a first processor receiving said output provided by said sensor, said first processor calculating a risk factor as a function of said output provided by said sensor, said first processor providing an output signal having information concerning a condition of the driver of the host vehicle in response to said risk factor exceeding a predetermined threshold value; and
a communication unit receiving said output signal from said first processor and transmitting said information for retrieval by the other vehicles in the vicinity of the host vehicle.

Abstract
A driver advisory system is provided for use in a host vehicle and for transmitting to drivers of other vehicles information regarding the status of a driver of the host vehicle. The driver advisory system includes a sensor, a first processor and a communication unit. The sensor monitors a physical condition of the driver of the host vehicle. The sensor provides an output quantifying the physical condition of the driver of the host vehicle. The first processor receives the output provided by the sensor. The first processor calculates a risk factor as a function of the output provided by the sensor. The first processor provides an output signal having information concerning the condition of the driver of the host vehicle in response to the risk factor exceeding a predetermined threshold value. The communication unit receives the output signal from the first processor and transmitting the information for retrieval by the other vehicles in the vicinity of the host vehicle.

22-1. A method of transmitting and processing information regarding the status of a driver between a host vehicle and a second host vehicle, the method comprising the steps of:
-
determining the instant location of the host vehicle;
receiving messages transmitted from a second host vehicle regarding the condition of a driver of the second host vehicle, and a position and heading of the second host vehicle;
calculating a risk factor based on an output quantifying the physical condition of the driver of the second host vehicle;
calculating a distance between the host vehicle and the second host vehicle; and
providing to the driver of the host vehicle an alert signal in response to the risk factor and the distance between the host vehicle and the second host vehicle falling below predetermined threshold values.
