Abstract
A method for awakening a drowsy driver includes monitoring the drowsiness level of the driver and alerting the driver. The driver is alerted by regulating the temperature in the vehicle interior, releasing oxygen in the vehicle interior, and adjusting the positioning of a window and/or sunroof to vent fresh cooler air into the vehicle. The window and/or sunroof are opened proportionally to the drowsiness level of the driver. The wind entering the vehicle also creates an audible alert which assists in awakening the driver.
