Bosch technology to detect drowsy drivers

Developed by engineers at Bosch, the technology – which is scheduled to go into production in 2022 – uses a camera integrated in the steering wheel to detect when a driver’s eyelids are getting heavy, when they are distracted, and when they turn their head toward their passenger or the rear seats.

Intelligent image-processing algorithms and machine learning technologies - trained using real-world examples - are then able to make a judgement on how tired the driver is on the basis of factors such as eyelid position and eye-blink rate.

According to Bosch, if the system determines that the driver is tired or distracted, it will then provide an alert or warning and use the driver assistance systems to intervene. “If the car knows what its driver and occupants are doing, driving will become safer and more convenient,” commented Harald Kroeger, member of the Robert Bosch GmbH board of management.
