Method and device for diagnosing in a motor vehicle a driver's fitness drive

The method as defined in one of the foregoing claims,

• wherein an electrocardiogram of the driver is measured in the vehicle as a physiological measured value.

The method as defined in one of the foregoing claims,

• wherein the eyelid blink frequency of the driver is sensed in the vehicle as a physiological measured value.

The method as defined in one of the foregoing claims,

• wherein physiological data measured in stationary fashion in the driver's home context, for example ergometric data measured on ergometric devices, and biographical data such as age, weight and gender, are used as health-relevant data.

The method as defined in one of the foregoing claims,

• wherein blood analysis values, e.g. the blood sugar level, of the driver obtained in the home context are used as health-relevant stationary data.

The method as defined in one of the foregoing claims,

• wherein if no stationary health-relevant physiological measured values concerning the driver are measurable or are present, standard values are assumed and are refined using inputted biographical data such as gender, age, and weight.

The method as defined in one of the foregoing claims,

• wherein the instantaneous traffic situation is estimated from the number, speed, and heading of other vehicles and from relevant driving direction information for the vehicle, and combined with instantaneous operating state data for the relevant motor vehicle, in particular its own heading and speed, and the driver stress is calculated therefrom.

The method as defined in one of the foregoing claims,

• wherein a learning system is used as the expert system;
• and initially, before a valid diagnosis of driving capability is issued, a learning phase with at least one test drive by the driver is performed in that vehicle, comprising a variety of stress levels and traffic situations.
