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.
