Vehicle Deceleration Control for Path-Relevant Obstacle Avoidance

The patent segments obstacles into different categories (dynamic obstacles on the same lane, dynamic obstacles on other lanes, static obstacles) and applies different control strategies to each category. The processing module selectively processes only dynamic obstacles on the same lane for emergency braking decisions, while excluding other obstacle types, thereby resolving the contradiction between comprehensive detection and avoiding unnecessary braking.

The patent applies partial action by not processing all detected obstacles uniformly. Instead, it selectively processes only the subset of obstacles (dynamic obstacles on the same lane) that require emergency braking responses, while ignoring other obstacle types. This partial processing approach prevents unnecessary emergency braking while maintaining adequate safety coverage.

The patent applies local quality by assigning different processing qualities to different obstacle types. Dynamic obstacles on the same lane receive high-priority processing with emergency braking responses, while dynamic obstacles on other lanes and static obstacles receive lower-priority or no processing. This differentiated local quality approach maintains safety responses for critical obstacles while providing control flexibility for non-critical situations.

The patent introduces dynamic processing based on obstacle characteristics and vehicle state. The determination module dynamically decides whether to process each obstacle based on real-time conditions such as obstacle type, vehicle speed, and lane position. This dynamic approach allows the system to adapt its control flexibility according to the specific situation while maintaining safety responses when necessary.

The patent segments the deceleration control into different levels based on obstacle type. Maximum deceleration is applied only to dynamic obstacles on the same lane that pose immediate collision risks, while no deceleration or reduced deceleration is applied to other obstacle types. This segmentation prevents unnecessary braking events that would degrade passenger experience while maintaining collision avoidance for critical obstacles.

The patent converts the potential harm of comprehensive obstacle processing into benefit by using the detected obstacle information selectively. The system benefits from comprehensive detection capability but converts the potential harm of unnecessary braking into benefit by filtering out non-critical obstacles from the control decision process, thereby improving passenger experience while maintaining collision avoidance effectiveness.
