Straddle Vehicle Rear Detection Region Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing straddle type vehicle detection systems fail to adapt detection region settings based on turning direction and radius, leading to blind spots and erroneous detections during vehicle turns.
Innovation Solution
A straddle type vehicle equipped with a rear detection unit and notification system that acquires travel information to identify turning direction and radius, dynamically changing straight-ahead detection region settings to a curved shape, preventing detection omission and erroneous detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed straight-ahead detection region settings are used during turning, then the detection system structure remains simple, but blind spots occur in the rear detection region depending on turning direction and radius
Solution Approach 1:
The detection region settings are made dynamic by automatically adjusting them based on the vehicle's turning direction and turning radius. The control unit receives turning information from sensors and dynamically modifies the detection region parameters, transforming the fixed detection system into an adaptive one that responds to real-time vehicle state changes.
Solution Approach 2:
The invention changes the detection region parameters (such as detection angles, range, and sensitivity) based on the vehicle's turning state. When the vehicle turns, the control unit adjusts the detection region settings to compensate for the changing geometry, ensuring continuous coverage of critical areas while maintaining detection accuracy.
2Ease of operation
If fixed detection region settings are used, then the control system remains simple, but regions difficult for the driver to visually recognize may occur
Solution Approach 1:
The control unit continuously receives feedback from sensors about the vehicle's turning direction and radius, and uses this feedback to adjust the detection region settings. This closed-loop control ensures that the detection regions remain optimized for driver visibility and safety regardless of the vehicle's turning state.
Solution Approach 2:
The system performs preliminary adjustments to the detection region settings before blind spots can form. By proactively adjusting the detection regions based on detected turning motion, the system prevents the formation of unsafe blind spots rather than reacting to them after they occur.
3Measurement precision
If detection region settings are changed based on turning state, then detection accuracy is improved, but the processing complexity increases
Solution Approach 1:
The detection region is divided into multiple segments or zones, each with optimized settings for specific turning scenarios. The control unit selectively activates appropriate segments based on the vehicle's turning state, reducing the overall processing complexity while maintaining high detection precision in each active segment.
