Vehicle Control Apparatus Dynamic Detection Width Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems experience response delays when determining if another vehicle is entering or departing from the own lane, leading to potential safety issues due to gradual changes in detection parameters.
Innovation Solution
A vehicle control apparatus with a setting, determination, and correction means that adjusts parameters based on relative lateral movement between vehicles, using a probability map to quickly assess if another vehicle is in the path, thereby improving responsiveness.

Engineering Contradiction Analysis
1Measurement precision
If the width of detecting the position of other vehicle is changed to prompt entry or departure, then the detection accuracy is improved, but the response time increases due to gradual parameter changes
Solution Approach 1:
The patent applies dynamics by making the detection width parameter changeable based on vehicle behavior detection. The control unit dynamically adjusts the detection width from a first width (for normal operation) to a second width (when lane change behavior is detected), allowing the system to adapt to different operational states and resolve the contradiction between detection accuracy and response time.
Solution Approach 2:
The patent directly implements parameter changes by modifying the detection width parameter. When lane change behavior is detected, the system changes the detection width parameter from the first width to the second width, enabling rapid response to lane change events while maintaining detection accuracy through parameter optimization.
2Device complexity
If a fixed detection width is used, then the device complexity is reduced, but the ability to detect lane changes quickly deteriorates
Solution Approach 1:
The system transitions from a static detection width to a dynamic one by introducing behavior detection and conditional parameter adjustment. The control unit detects lane change behavior and automatically adjusts the detection width, providing quick lane change detection without requiring complex manual intervention or overly complicated system architecture.
Solution Approach 2:
The patent implements feedback by continuously monitoring vehicle behavior and using this information to adjust the detection width. The control unit receives feedback about lane change behavior from the detection unit and responds by adjusting the detection width parameter, creating a closed-loop system that improves detection speed while maintaining manageable complexity.

AI summary
A vehicle control apparatus mounted to an own vehicle to control the own vehicle according to a position of other vehicle ahead of the own vehicle is provided. The device includes a setting means setting a parameter indicating a position of the other vehicle relative to the own vehicle in a lateral direction perpendicular to the path of the own vehicle, a determination means determining whether the other vehicle is in the path of the own vehicle based on the parameter, a detection means detecting whether a relative movement has been made in the lateral direction by at least one of the own vehicle and the other vehicle, and a correction means correcting the parameter when a relative movement has been made in the lateral direction.
