Vehicle Remote Parking Distance Detection Using Camera Lens Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle remote parking systems face challenges in accurately determining the distance between the vehicle and the mobile device, which is crucial for enabling remote control features while adhering to regulatory requirements, such as maintaining a certain threshold distance to ensure safe operation.
Innovation Solution
The system employs a method using a camera with adjustable lenses and focal lengths to determine the distance between the vehicle and the mobile device by overlaying graphics and using digital models, ensuring that the vehicle control system can only be activated when the user is within a safe operational range, with visual, audible, and tactile indicators to manage the user's positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user is allowed to control the vehicle remotely from a greater distance, then the ease of operation is improved, but the safety and regulatory compliance deteriorate
Solution Approach 1:
The system continuously monitors the distance between the mobile device and vehicle, providing real-time feedback through visual, audible, and tactile indicators. When the distance exceeds the threshold, the system warns the user and eventually terminates remote control, ensuring safety compliance while enabling convenient operation within safe limits
Solution Approach 2:
The remote control system dynamically adjusts its operational state based on the real-time distance measurement. The system transitions between different states (normal operation, warning, termination) depending on whether the user remains within the safe distance threshold, allowing flexible operation while maintaining safety constraints
2Reliability
If the distance threshold is reduced to ensure safety, then the reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The system provides continuous feedback to the user about their distance from the vehicle through multiple indicator types. This allows the user to understand and maintain the required distance threshold, making the safety constraint transparent and manageable rather than arbitrary and restrictive
3Reliability
If the system provides continuous distance monitoring and warnings, then the safety is improved, but the device complexity increases
Solution Approach 1:
The feedback system is segmented into multiple independent indicator channels (visual display, audible warning, tactile vibration). Each indicator handles a specific aspect of distance monitoring, allowing the system to provide comprehensive safety feedback without requiring a single complex monitoring mechanism
Solution Approach 2:
The system uses an intermediary feedback mechanism that translates the raw distance measurement into user-comprehensible warnings and indicators. This intermediary layer simplifies the interaction between the complex distance monitoring system and the user, making the overall system more manageable
