Driver assistance system for a motor vehicle, motor vehicle, and method for operating a driver assistance system

摘要

A driver assistance system is provided for a motor vehicle, which has a first ascertainment device, the first ascertainment device implemented to ascertain at least one parameter that characterizes a possible fatigue of a current driver of the motor vehicle. In addition, the driver assistance system has a second ascertainment device, which is implemented to ascertain a degree of fatigue of the driver based on the at least one ascertained parameter. In addition, the driver assistance system has an opening device, which is implemented to at least partially open at least one window of the motor vehicle if the ascertained degree of fatigue of the driver exceeds a first predetermined threshold value.

主权项

1. A driver assistance system for a motor vehicle comprising:
sensors determining an ambient air temperature outside the motor vehicle, an interior temperature of the motor vehicle, and a current weather condition surrounding the motor vehicle; a first ascertainment device configured to ascertain at least one parameter that characterizes a driver fatigue; a second ascertainment device configured to ascertain a degree of driver fatigue based on the at least one parameter; and an opening device configured to at least partially open at least one window of the motor vehicle when the degree of driver fatigue exceeds a first predetermined threshold value, when the current weather condition surrounding the motor vehicle is substantially free of precipitation, and when the interior temperature of the motor vehicle is greater than the ambient air temperature outside the motor vehicle.
