Vehicle Turning Camera and Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle systems with permanently switched-on turning cameras and displays for supporting drivers during turns lead to energy inefficiency and driver distraction, as well as the risk of ignoring potential hazards during critical maneuvers.
Innovation Solution
A control device that automatically switches the turning camera and display on and off based on the vehicle's driving speed and turn signal activity, ensuring they are only active during potential turning maneuvers, thereby reducing energy consumption and minimizing unnecessary distraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the turning camera and display are permanently switched on, then the driver can see potential hazards during turning maneuvers, but energy consumption increases and the driver may be distracted during non-turning situations
Solution Approach 1:
The system dynamically adjusts the operational state of the camera and display based on real-time detection of turning maneuvers. The control unit activates the camera and display only when a turning maneuver is detected through speed and turn signal evaluation, rather than maintaining a static permanently-on state. This dynamic activation resolves the contradiction by ensuring safety functionality is available when needed while minimizing energy consumption during normal driving.
Solution Approach 2:
The system employs periodic activation of the camera and display based on detected turning events rather than continuous operation. The control unit periodically activates these components during identified turning maneuvers and deactivates them during straight-line driving, creating a rhythmic on-off pattern that balances safety requirements with energy efficiency.
2Reliability
If the turning camera and display are permanently switched on, then the driver can monitor surroundings during turns, but the driver may disregard the display during critical moments due to distraction
Solution Approach 1:
The system dynamically controls the display visibility based on turning maneuver detection. By activating the display only during actual or intended turning maneuvers, the system ensures that the driver's attention is drawn to the display at critical moments when hazard monitoring is most needed, rather than creating constant visual competition during all driving situations.
Solution Approach 2:
The system extracts the display functionality from continuous operation and isolates it to specific turning maneuver contexts. By removing the display from permanent visibility and presenting it only when turning is detected, the system eliminates unnecessary visual distractions during straight-line driving while ensuring the display is prominently available during critical turning situations.
3Use of energy by moving object
If the turning camera and display are activated based on speed and turn signal evaluation, then energy consumption is reduced and driver distraction is minimized, but the system may fail to activate during unexpected turns without turn signal
Solution Approach 1:
The system performs preliminary evaluation of turning intent by monitoring turn signal activation and speed patterns before activating the camera and display. This preliminary detection mechanism allows the system to anticipate turning maneuvers and activate the safety functionality in advance, while the continuous monitoring of multiple parameters (speed, turn signal state) ensures comprehensive detection coverage.
