Dynamic Lane Change Range Adjustment for Vehicle Safety

The patent applies dynamics by making the monitoring range adjustable based on the necessity level. When the necessity level is high, the monitoring range is reduced to allow faster lane changes. When the necessity level is low, the monitoring range is expanded to ensure higher safety. This dynamic adjustment resolves the contradiction between safety and responsiveness.

The patent changes the parameter of monitoring range size according to the necessity level of lane change. By adjusting this parameter dynamically, the system can prioritize either safety or responsiveness depending on the current driving situation, thus resolving the technical contradiction.

The monitoring range is dynamically adjusted based on the necessity level rather than being fixed. This allows the system to reduce the range when quick lane changes are needed while maintaining adequate detection accuracy for the reduced range, resolving the contradiction between speed and accuracy.

The patent applies local quality by focusing detection resources on the specific reduced range when necessity level is high, rather than uniformly reducing detection quality across all areas. The system maintains high detection accuracy within the smaller, relevant monitoring zone.

Instead of using a permanently large monitoring range that would increase system complexity, the patent uses a dynamic monitoring range that expands or contracts based on the necessity level. This approach maintains safety when needed while avoiding the constant complexity of managing a large fixed range.

The control system achieves multiple functions through a single mechanism: when the monitoring range is large, it provides comprehensive safety detection; when reduced, it enables faster lane changes. This multi-functionality avoids the need for separate systems for different monitoring scenarios, reducing overall complexity.
