Abstract
The present disclosure relates to a method for determining the fatigue of a driver of a motor vehicle, wherein the fatigue is determined while taking into account the steering behavior of the driver, characterized in that the method includes the following steps: determination of a hysteresis of the steering system or the fatigue detection system, and taking into account the detected hysteresis in the determination of the fatigue of the driver. Furthermore, the disclosure relates to a device that is set up to execute the method.
Claims11
A method for determining a fatigue of a driver of a motor vehicle, the method comprising:
- determining a hysteresis of at least one of (i) a steering system and (ii) a fatigue detection system, based on a direct relationship between a steering angle signal and a lateral acceleration signal indicating a turn rate of the vehicle;
- determining the fatigue of the driver based on a steering behavior of the driver and the determined hysteresis;
- and
- controlling a driver assistance system to take over control of the motor vehicle with an automated driving function based on the fatigue of the driver.
A device for determining a fatigue of a driver of a motor vehicle, the device configured to:
- determine a hysteresis of at least one of (i) a steering system and (ii) a fatigue detection system, based on a direct relationship between a steering angle signal and a lateral acceleration signal indicating a turn rate of the vehicle;
- determine the fatigue of the driver based on a steering behavior of the driver and the hysteresis of the at least one of (i) the steering system and (ii) the fatigue detection system;
- and
- control a driver assistance system to take over control of the motor vehicle with an automated driving function based on the fatigue of the driver.
