METHOD FOR OPERATING A MOTOR VEHICLE WITH THE HELP OF PHYSIOLOGICAL VITAL DATA, MOTOR VEHICLE AND MOBILE TERMINAL DEVICE

A method is disclosed for operating a motor vehicle, wherein a control device determines a first index value from vital physiological data received from a sensor device at a first point in time. The control device generates a first actuator signal describing the activation of first actuator function, to be carried out by a first actuator that is selected based on the first index value. At a second point in time, the sensor device records additional vital physiological data and identifies a second index value. Both index values, each describing a physiological state of the user, are compared, and the result is used to determine whether the second index value meets an efficacy criterion that describes a predetermined degree of improvement in the physiological state brought about by the activated actuator function. If the second index value meets the efficacy criterion, the first actuator function is activated as soon as an index value is identified that describes the same physiological state.
