It took an acquisition to give auto mirror supplier Gentex Corp. an enhanced view of driver and passenger behavior with machine vision, depth perception and micro-vibration detection.
Gentex's sensor configuration allows the system to monitor the driver and the vehicle cabin, assessing occupants' behavior, gestures and activities to ensure safety and comfort, Gentex said.
Gentex is known for supplying most major automakers with connected-car technologies and advanced electronic features for driver vision and safety, such as full-display camera rearview mirrors.
"Monitoring the driver and vehicle occupants becomes increasingly important as we move through the levels of driving automation," Neil Boehm, Gentex vice president of engineering and chief technology officer, said in a statement. "We're engineering a comprehensive and scalable platform based on robust sensor fusion techniques that will allow us to provide features for today's vehicles as well as transitionary and completely autonomous vehicles."
In September, Gentex announced the acquisition of Guardian Optical Technologies of Tel Aviv, which developed an infrared-sensitive, high-resolution camera with machine vision, depth perception and micro-vibration detection. The acquisition was key to putting together the full driver and in-cabin monitoring system, Boehm said.
Through a camera behind the rearview mirror, the system tracks the driver's head pose, eye gaze and other features to assess distraction and drowsiness, along with readiness to assume control for semi-autonomous vehicles, Gentex said.
