Vehicle Camera View-Angle Control for Blind Spot Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle-mounted cameras have fixed angles of view, leading to blind spots and reduced safety during changing driving scenarios, such as turns or uphill/downhill driving, as they fail to adapt to real-time vehicle status parameters.
Innovation Solution
A method and apparatus that dynamically control the angle of view of vehicle-mounted cameras based on real-time status parameters, such as speed, steering angle, and incline, using preset intervals and interpolation to provide more accurate visual information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the angle of view of the camera remains fixed relative to the vehicle, then the camera structure is simple and stable, but blind areas appear in different driving scenarios resulting in reduced vehicle safety
Solution Approach 1:
The patent implements dynamic angle of view adjustment by making the camera's field of view changeable based on real-time vehicle status parameters. The controller dynamically adjusts the angle of view according to driving conditions such as speed, steering angle, and acceleration, transforming the fixed camera system into an adaptive one that eliminates blind spots while maintaining operational simplicity through automated control.
Solution Approach 2:
The patent changes the operational parameters of the camera system by adjusting the angle of view parameter based on vehicle status parameters. The controller modifies the camera's viewing parameters in real-time according to driving conditions, allowing the system to adapt to different scenarios without requiring physical reconfiguration or complex mechanical adjustments.
2Reliability
If multiple cameras are equipped to cover different angles, then visual information coverage is improved, but the device complexity and cost increase
Solution Approach 1:
Instead of using multiple fixed cameras to cover all possible angles, the patent employs a single camera with dynamically adjustable angle of view. The controller switches or adjusts the camera's viewing angle based on driving conditions, providing comprehensive visual coverage equivalent to multiple cameras while reducing system complexity and cost.
Solution Approach 2:
The patent makes a single camera perform multiple functions by enabling it to capture different fields of view according to driving scenarios. The camera serves as a universal visual sensor that can adapt to various driving conditions (straight driving, turning, accelerating, decelerating) by adjusting its angle of view, replacing the need for multiple specialized cameras.
3Reliability
If the angle of view is adjusted in real-time based on vehicle status, then blind spots are reduced and safety is improved, but the control system complexity increases
Solution Approach 1:
The patent implements a feedback control system where the controller receives real-time vehicle status parameters (speed, steering angle, acceleration) and adjusts the camera's angle of view accordingly. This closed-loop feedback mechanism automatically adapts the camera to driving conditions, improving safety while keeping the control system manageable through rule-based or algorithmic decision-making.
Solution Approach 2:
The camera system performs self-adjustment based on vehicle status parameters without requiring manual intervention. The controller automatically determines the appropriate angle of view based on current driving conditions, enabling the system to serve itself and adapt to changing scenarios without adding complex user interfaces or manual control mechanisms.
