Functionality of ATTENTION ASSIST and DEAD ANGLE COVERAGE Systems
ATTENTION ASSIST operates through a multi-sensor fusion system combining:Response triggers and actions:
1. Warning Phase (Yellow LED + Acoustic Signal): Activated if the system detects >30% reduction in steering responsiveness or >20% deviation from expected lane position over 30 seconds.
2. Intervention Phase (Red LED + Haptic Seat Vibration): If no corrective action is taken, the system gradually reduces speed (up to 10 km/h or 6 mph) and tightens seat belt tensioners.
3. Emergency Phase (Automatic Braking): If the driver remains unresponsive, the system initiates controlled braking to a safe stop, prioritizing lane-keeping to avoid secondary collisions.
DEAD ANGLE COVERAGE utilizes:
Sensor placement and response logic:
