MONTVALE, NJ – The engineers at Mercedes have developed a new system to monitor the drowsiness of a driver and provide an alert before the driver falls asleep and causes a crash, according to http://rumors.automobilemag.com. A steering shaft sensor now monitors inputs to a tenth of a degree to help determine a driver’s reaction time and the severity of corrections made to keep the car on course. Several other factors are monitored, but not the driver’s eyes. Other attention monitoring systems focus on the eyes, but those systems do not work for people wearing glasses.
It takes 20 to 30 minutes of normal driving for the car to learn individual driving habits and determine which inputs are normal. After that, the Mercedes system will monitor the driver and give an audible and visual alert when it detects a period of no corrections and then an over-correction from the driver.
