General Motors has filed a patent for an eye-tracking system that enables a car to automatically change lanes on the highway when the driver glances at the side mirror. The innovation aims to make semi-autonomous driving smoother and more intuitive.
General Motors has filed a patent for an eye-tracking system that enables a car to automatically change lanes on the highway when the driver glances at the side mirror. The innovation aims to make semi-autonomous driving smoother and more intuitive.
How GM’s Eye-Tracking Tech Works
The system uses interior cameras to monitor the driver’s eyes. When the driver looks at the left or right side mirror for more than a second, the car checks blind spots using radar and surround cameras. If the lane is clear, the vehicle initiates a lane change automatically, with turn signals activated.
What Components Are Involved?
- High-resolution interior cameras for eye and head tracking
- AI processors for real-time gaze analysis
- Radar sensors and surround cameras for blind-spot monitoring
- Electronic steering system integrated with safety systems
How Is This Different from Current Lane-Change Systems?
Current systems like GM Super Cruise or Tesla Autopilot require the driver to manually activate the turn signal to initiate a lane change. The new patent eliminates this step, making the experience more seamless and natural, especially during long highway drives.
Will the Tech Appear in Future GM Cars?
A patent does not guarantee immediate commercial release, but it signals GM’s direction toward integrating eye-tracking into future autonomous driving systems. The feature is expected to debut in luxury models like Cadillac before spreading to other brands.
When Could It Reach the Gulf Region?
GM has not announced a timeline. Patents typically require years of development and testing. If approved, the technology would likely arrive in Saudi Arabia and the UAE 12–18 months after its US and European launch.
What’s the Relevance for Gulf Drivers?
For drivers in the Gulf, where long highway commutes are common, a hands-free lane-change system could reduce fatigue. However, extreme heat and dust may pose challenges for interior cameras and sensors, requiring robust calibration.
Frequently Asked Questions
Is GM's eye-tracking technology safe?
Yes. The system uses interior cameras to ensure the driver is attentive and checks blind spots with radar and cameras before initiating a lane change.
When will GM's glance-based lane change be available?
GM has not set a release date. The patent is an early step, and development and testing may take several years before appearing in production cars.
Will the technology work in all GM vehicles?
It is expected to debut in luxury models like Cadillac, then expand to Chevrolet and GMC. Availability depends on necessary hardware like interior cameras and radar sensors.
How does this compare to Tesla Autopilot?
Tesla Autopilot requires the driver to use the turn signal to change lanes. GM's patent removes that step, making the process more intuitive and natural.
