Method and device for diagnosing in a motor vehicle a driver's fitness drive
First Claim
1. A method for diagnosing the driving capability of a driver of a motor vehicle, in which changes in driver condition are ascertained from physiological measured values derived from the driver while driving in the vehicle and evaluated, and if the changes are serious, a warning is issued or remedial actions are initiated, wherein the physiological measured values acquired while driving in the vehicle are combined by an expert system with health-relevant data, ascertained in stationary fashion or estimated, for the driver;
- and changes in driver condition are weighted and interpreted by the expert system with a variable indicating driver stress that is estimated from data present or derived in the vehicle, in particular concerning the instantaneous traffic situation and instantaneous vehicle operating state, in order to detect whether or not the driver is capable of driving.

Abstract
The invention relates to a method for diagnosing the driving capability of a driver of a motor vehicle (5), in which changes in driver condition are ascertained from physiological measured values derived from the driver while driving in the vehicle and evaluated, and if the changes are serious, a warning is issued or remedial actions are initiated, wherein the physiological measured values ascertained while driving in the vehicle are combined by means of a corresponding expert system (10) with health-relevant data for the driver ascertained in stationary fashion, and with data indicating driver stress that are estimated in particular from the instantaneous traffic situation and instantaneous operating state of the vehicle (5), and changes in the driver'"'"'s condition are weighted with the estimated driver stress and interpreted; and an apparatus (1) for carrying out the method, which is characterized in that the expert system (10) is implemented in an onboard computer of the vehicle (3) which is connected via a bus (3) internal to the vehicle to a mobile driver condition sensor suite (4) that supplies the physiological measured values; to a memory/transfer medium (15, 18) that delivers the biographical data and/or the health-relevant data ascertained in stationary fashion; and to an ACC system and driving direction system (11) internal to the vehicle.
