Method for operating a vehicle
Operation of a vehicle involves determining a cortisol content in the blood of a driver of the vehicle. The cortisol content in the blood of the driver is derived using a cortisol content in the sweat of the driver, detected sensorially by a wearable data processing unit. Depending on the derived cortisol content of the driver, settings of vehicle parameters and/or vehicle functions are adjusted to reduce the risk of an accident.
1. A method for operating a vehicle, the method comprising:
determining a cortisol content in blood of a driver of the vehicle using a cortisol content in sweat of the driver, wherein the cortisol content in sweat of the driver is detected sensorially by a wearable data processing unit;
adjusting, depending on the determined cortisol content in the driver, settings of parameters of the vehicle or functions of the vehicle functions to reduce a risk of an accident; and
determining a hazard level for the risk of an accident involving the driver using the determined cortisol content in the blood of the driver and a determined level of driving experience of the driver.
2. The method of claim 1 , wherein, depending on the determined hazard level, the settings of the parameters of the vehicle or the functions of the vehicle are adjusted by
specifying a maximum speed for a further driving operation of the vehicle,
limiting a maximum possible acceleration of the vehicle,
outputting a warning in the vehicle when a distance, which is greater than a minimum target distance, between the vehicle and a vehicle driving in front is not met,
outputting a warning when the vehicle prematurely leaves a current lane and an intervention limit for a lane departure warning system for a steering intervention is lowered, or
preventing selection of a sport driving mode.
3. The method of claim 1 , further comprising:
identifying the driver in the vehicle using the driver's sweat.
4. The method of claim 1 , further comprising:
transmitting detected sweat data of the driver to a computing unit in the vehicle for evaluation and processing.
5. The method of claim 4 , wherein a database of potential drivers of the vehicle is stored in the computing unit.
6. The method of claim 5 , wherein a date of birth of a respective one of the potential drivers and personal sweat data for identifying the respective one of the potential drivers are stored in the database.
7. The method of claim 6 , wherein the respective one of the potential drivers is registered in the database by an electronically readable driving license the first time the sweat data of the respective one of the potential drivers is detected.
8. The method of claim 7 , wherein the level of driving experience of the driver is determined using a date of issue of the driving license.
9. The method of claim 1 , wherein all changes undertaken related to the settings of the parameters of the vehicle parameters or the functions of the vehicle, as well as a determined current cortisol content in the sweat or blood of the driver are shown to the driver of the vehicle on a display unit of the vehicle.
