Driver Monitoring System for Semi-Autonomous Driving in CT6

Osram Opto Semiconductors and Joyson Safety Systems are equipping the new Cadillac CT6 with a system for semi-autonomous driving. Super Cruise is a hands-free driving technology for the highway.

Super Cruise represents the next evolution of adaptive cruise control and works only if the driver is paying attention to the road ahead. To that end, Joyson Safety Systems worked with Osram to design a steering wheel that features an embedded infrared camera that tracks the driver’s head position and gaze to confirm the driver’s eyes are on the road at all times. If the driver looks away from the road for too long, the system will send a series of alerts for the driver to resume supervision of the road. In the limited event when a driver becomes completely unresponsive, the Cadillac CT6 utilizes the full capability of onboard driver assistance technologies to bring the car to a controlled stop.

The Joyson Safety Systems’ steering wheel is equipped with Osram’s Oslon Black SFH 4715S IREDs that helps track eye movement, as well as with RGB Multiled of the semiconductor company to indicate to the driver when the Super Cruise system is operating and what function it is currently performing. For instance, the LED lights turn green when the Super Cruise system is engaged. The lights turn blue when the system senses the driver might not being paying attention, and turn red when the system disengages. The LEDs also blink when the IREDs are blocked from viewing the driver’s eyes.
