Cross Traffic Camera Auto-Activation via Turn Signal and Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle safety systems often provide limited and distracting information to drivers, particularly when navigating turns or merging into traffic, as they rely on manual activation and do not effectively communicate data in a timely and non-distracting manner.
Innovation Solution
A method for automatically activating a cross-traffic camera system by integrating vehicle turn signals with a vehicle system controller, which displays relevant camera feeds on primary or secondary displays only when necessary, such as during turns or when the vehicle is below a preset speed, and terminates the display after the turn is completed or the vehicle exceeds the preset speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cross traffic camera system is continuously displayed to provide comprehensive safety information, then driver awareness is improved, but driver distraction increases
Solution Approach 1:
The camera display operates periodically rather than continuously, activating only during specific driving conditions such as turns or when vehicle speed is below a preset threshold. This periodic activation provides necessary safety information while minimizing unnecessary visual distractions to the driver during normal driving conditions.
Solution Approach 2:
The system dynamically adjusts its operation based on real-time driving conditions, including vehicle speed, turn signal status, and steering wheel position. The display transitions between active and inactive states according to these changing conditions, optimizing the balance between providing safety information and avoiding driver distraction.
2Ease of operation
If the camera system is manually activated, then driver control is maintained, but timely information delivery is delayed
Solution Approach 1:
The system automatically detects and responds to driving conditions without requiring manual driver input. By monitoring turn signals, vehicle speed, and steering position, the system self-activates the camera display when safety information is needed, eliminating the delay associated with manual activation while maintaining appropriate control.
Solution Approach 2:
The system continuously monitors driving conditions and provides feedback through automatic display activation. The feedback loop detects when a turn is initiated or when the vehicle is moving slowly, and automatically activates the camera display to provide timely safety information without requiring driver intervention.
3Loss of information
If the camera display is activated during all maneuvers, then complete information is provided, but unnecessary distractions occur
Solution Approach 1:
The system applies different operational characteristics to different driving scenarios. Instead of uniform activation during all maneuvers, the display is selectively activated based on the specific local condition - such as turns versus straight-line travel, or low-speed versus high-speed operation - providing information completeness only where necessary while avoiding unnecessary distraction elsewhere.
Data Source
AI summary
A method is provided for automatically activating a car's cross traffic camera system when turning a corner and displaying the camera feed on a dashboard mounted display, thereby enhancing cross traffic visibility and making the maneuver safer. The system can be configured to anticipate an upcoming turn based on use of the turn signal alone, or the turn signal in combination with vehicle speed. The display of the camera's data feed is terminated after completion of the turn, where turn completion is typically based on (i) deactivation of the turn signal, (ii) the position of the steering wheel, or (iii) vehicle speed.
