Solution Overview
Problem
Existing driving assistance technologies face challenges in accurately detecting nearby vehicles, particularly when the side surface of the vehicle is facing the detection system, leading to decreased detection accuracy.
Innovation Solution
A driving assistance device equipped with a recognition unit, a travel wheel detection unit, an operation determination unit, and an operation unit, which detects travel wheels in the environment and determines whether they satisfy specific operation conditions for activating safety devices, thereby improving detection accuracy and reducing excessive safety device operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the detection system relies on standard vehicle detection methods, then the system is simple to implement, but the detection accuracy decreases when the side surface of the nearby vehicle faces the detection system
Solution Approach 1:
The detection system segments the vehicle detection task into multiple components: standard vehicle detection, travel wheel detection, and operation condition evaluation. By dividing the detection object into vehicle body and travel wheels, the system can accurately detect vehicles even when the side surface faces the detection system, as travel wheels are visible from side angles.
Solution Approach 2:
The travel wheel detection unit acts as an intermediary detection mechanism when standard vehicle detection fails. By detecting travel wheels as a surrogate indicator of vehicle presence, the system maintains detection accuracy in scenarios where the vehicle body is not directly visible, such as when the side surface faces the detection system.
2Reliability
If the safety device is activated frequently to ensure safety, then the safety level increases, but the excessive activation reduces driver trust and causes inconvenience
Solution Approach 1:
The operation determination unit implements feedback by evaluating multiple conditions (travel wheel detection results, vehicle position, distance, and operation patterns) before activating the safety device. This feedback mechanism ensures activation only when truly necessary, balancing safety with driver convenience by avoiding unnecessary alerts while maintaining high safety standards.
Solution Approach 2:
The system performs partial detection by focusing specifically on travel wheels rather than requiring complete vehicle detection. This partial action approach allows the safety device to activate based on sufficient evidence (travel wheel presence) without requiring full vehicle verification, thereby maintaining safety while reducing excessive activations.
