Enabling Safer Hands-Free Driving
My work on interior sensing at Aptiv has been deployed in GM’s Super Cruise and Driver Attention Assist systems—the industry’s first true hands-free driving technology with integrated driver monitoring.
Driver Attention System
The system combines a small camera on the steering column with infrared LEDs on the steering wheel to monitor the driver’s head and eye position when Super Cruise is engaged.
Core Capabilities
Fatigue Detection
- Analyzes subtle cues: yawning, blink patterns, blink duration
- Monitors driver response time to alerts
- Triggers coffee cup icon suggesting rest breaks
- Haptic seat vibration and audio chimes for alerts
- Offers engagement options: phone a friend, play music, navigate to rest area
Short Duration Distraction
- Detects frequent short glances away from road
- Assesses look-away frequency in 30-second windows
- Prompts “keep eyes on road” messages
- Multi-modal alerts via display, haptics, and audio
Long Duration Distraction
- Recognizes continuous extended attention loss
- Progressive alert escalation
- Re-engagement prompts via multiple channels
Deployed Vehicles
The technology is now standard in:
- 2025 Cadillac Escalade IQ
- 2025 Chevrolet Tahoe
- Super Cruise-equipped GM vehicles
Impact
According to NHTSA, around 20% of crashes are directly attributed to driver states such as distraction, fatigue, medical events, and intoxication. This technology provides real-time, gentle reminders to stay engaged—an essential step toward safer roads.
Technical Contributions
- Developed robust eye-tracking algorithms for varied lighting conditions
- Created fatigue detection models trained on extensive drowsiness datasets
- Optimized inference for automotive-grade compute platforms
- Contributed to sensor fusion between camera and IR illumination systems
