Method and Assistance System for Assisting a Driver of a Motor Vehicle as well as Measuring Method and Measuring System for Determining a Mental State of a Driver of a Motor Vehicle
First Claim
1. A method for assisting a driver of a motor vehicle, comprising the following steps:
- measuring at least one value of at least one vital parameter of the driver correlated with the mental state of the driver and/or at least one value of at least one driving dynamics variable correlated with the mental state of the driver;
classifying the mental state of the driver with reference to the measured value of the vital parameter or the driving dynamics variable; and
generating a signal perceptible by the driver by means of a driver assistance system of the motor vehicle, wherein the signal is selected from a plurality of different signals in dependence on the classification of the mental state of the driver, or suppressing a signal of the driver assistance system and/or selecting at least one vehicle parameter in dependence on the classification of the mental state of the driver, whereinfor the vital parameter and/or the driving dynamics variable an expected range of values divided into at least one first and one second classification range each is determined, wherein the classification ranges each correspond to different mental states of the driver and the measured value of the vital parameter or the driving dynamics variable are associated to the first or the second classification range.
