Abstract: A control device for a vehicle for determining a comfort level of a driver, the control device being configured to: receive sensor output of a physiological sensor and a behavioral sensor, the physiological sensor measuring at least one physiological feature of the driver and the behavioral sensor measuring at least one behavioral feature of the driver, receive driving context information from a driving context detection unit, create a reference data set by recording the sensor output and the driving context information over a predetermined reference time period, determine a reference index for the comfort level of the driver based on the reference data set, and determine a comfort level index value of the driver, the index value being determined as a function of a current sensor output, current driving context information and the reference index. Further relates to a system and a method.

Abstract: A control device, system, and method for a vehicle to determine a driver's comfort level, configured to receive a first sensor output of a first physiological sensor measuring at least one first physiological feature of the driver, and receive a second sensor output of a second physiological sensor measuring at least one second physiological feature of the driver, create at least one reference data set by recording the first sensor output over a first predetermined reference time period and recording the second sensor output over a second predetermined reference time period being different than the first predetermined reference time period, determine at least one reference index for the comfort level of the driver based on the reference data set, and determine a comfort level index value of the driver, the index value determined as a function of the reference index and the current first and/or second sensor output.
