On-vehicle Tracking Control Turn Signal Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing on-vehicle tracking control systems struggle to accurately maintain or release tracking control based on the relationship between the own vehicle and other vehicles after acquiring information about the turn signal of a preceding vehicle, leading to potential discomfort for the driver due to unnecessary control actions.
Innovation Solution
An on-vehicle tracking control apparatus equipped with information acquiring means and control means, including turn signal determining means, which assesses the surroundings to reliably maintain or release tracking control by considering the relationship with other vehicles after detecting the turn signal of the preceding vehicle, using detectors like cameras, millimeter wave radar, and laser radar to gather data on traffic lanes and adjacent vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the tracking control is released early based on turn signal detection, then the responsiveness to preceding vehicle maneuvers is improved, but the reliability of tracking control may deteriorate due to unsafe lane changes
Solution Approach 1:
The system performs preliminary detection of turn signals before executing tracking control release. The turn signal detection unit detects turn signals in advance, and the control unit evaluates surrounding conditions (adjacent vehicles, lane information) before releasing tracking control, ensuring safe and timely responsiveness
Solution Approach 2:
The system continuously monitors surrounding conditions and provides feedback to the control unit. The control unit receives feedback from adjacent vehicle detection, lane information detection, and turn signal detection units to dynamically adjust tracking control decisions, ensuring reliable control based on real-time conditions
2Reliability
If the tracking control is maintained conservatively, then the safety and reliability are improved, but the responsiveness to preceding vehicle maneuvers deteriorates due to delayed control release
Solution Approach 1:
The system dynamically adjusts tracking control release timing based on surrounding conditions. When adjacent vehicles are detected or lane information indicates unsafe conditions, the control unit maintains tracking control longer. When conditions are safe, the control unit releases tracking control earlier, optimizing both safety and responsiveness
Solution Approach 2:
The control unit changes the threshold parameter for tracking control release based on detected conditions. The release threshold is adjusted higher (more conservative) when surrounding conditions are unsafe, and lower (more responsive) when conditions are safe, allowing adaptive control behavior
3Speed
If the threshold value for releasing tracking control is changed, then the responsiveness to turn signals is improved, but the adaptability to different surrounding conditions deteriorates
Solution Approach 1:
The system segments the control release decision into multiple independent evaluation components: turn signal detection, adjacent vehicle detection, lane information detection, and control unit synthesis. Each component independently evaluates its aspect, and the control unit integrates all inputs to make the final release decision, allowing comprehensive adaptability
Solution Approach 2:
The control unit performs multiple functions: it processes turn signal information, adjacent vehicle detection data, lane information, and synthesizes these into a unified tracking control release decision. This multi-functional approach allows the system to adapt to various surrounding conditions while maintaining responsive control
Data Source
AI summary
A tracking control apparatus for tracking a preceding vehicle includes information acquiring unit for acquiring information about surrounding the own vehicle, preceding vehicle determining unit for determining the preceding vehicle running ahead of the own vehicle, control unit controls the tracking control to be maintained or released, and turn signal determining unit for determining whether or not a turn signal of a turn signal unit of the preceding vehicle is active. The control unit maintains or releases the tracking control by determining the surrounding of the own vehicle concerning a traffic lane change by the preceding vehicle based on the information acquired by the information acquiring unit, when the turn signal determining unit determines that the turn signal of the turn signal unit is active.
