Vehicle Headlight Control Using Adaptive Debounce Logic

The patent applies dynamics by making the debounce time variable rather than fixed. The control unit adjusts the debounce time dynamically based on detected road situations (curves, intersections, pedestrian crossings) and vehicle speed. This allows the system to extend debounce time only when necessary to prevent dazzling, while maintaining shorter debounce times otherwise to preserve range of vision.

The patent changes the parameter of debounce time based on different operating conditions. By detecting road geometry, traffic signs, and vehicle speed, the system modifies the debounce time parameter adaptively. This resolves the contradiction by allowing long debounce times only in specific situations where dazzling risk exists, while using shorter debounce times in open roads to maintain visibility.

The patent implements feedback by continuously monitoring road situations through the traffic sign recognition device and other sensors. The control unit receives feedback about curves, intersections, and detected vehicles, then adjusts high beam activation accordingly. This feedback loop prevents dazzling by suppressing high beam only when road conditions indicate potential harm to other road users.

The patent applies preliminary action by predicting potentially hazardous situations based on detected road geometry and traffic signs before vehicles or pedestrians actually appear. The system prepares to suppress high beam in advance when curves or intersections are detected, preventing dazzling before it occurs while maintaining visibility on open stretches.
