Volvo Cars developing systems for Driver State Estimation; driver sensors
March 17, 2014
Volvo Cars is researching systems that can recognize and distinguish whether a driver is tired or inattentive. By placing a sensor on the dashboard to monitor aspects such as in which direction drivers are looking, how open their eyes are, as well as their head position and angle, it is possible to develop precise safety systems that detect a driver’s state and are able to adjust the car accordingly.
The analysis of the driver’s state, known as Driver State Estimation, in which driver sensors play an important role, is a field that may be key to self-driving cars in the future, Volvo suggests. The car will need to be able to determine for itself whether the driver is capable of taking control when the conditions for driving autonomously are no longer present. A driver sensor could be of assistance in this.
