Automatic Trailering Mirror Extension System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of extending and adjusting side view mirrors on a tow vehicle when approaching a trailer for hitching is time-consuming and tedious, requiring manual effort and lacking efficient automation.
Innovation Solution
A system that automatically adjusts the vehicle mirrors to a trailering position using a controller, memory device for saved mirror positions, detection devices (camera or radar), and a token on the trailer to identify the trailer and initiate the hitching operation, allowing the mirrors to extend and adjust to a predefined optimal viewing position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual extension and adjustment of side view mirrors is used when approaching a trailer, then the mirror position can be changed to provide increased visibility, but the process becomes time-consuming and tedious
Solution Approach 1:
The system performs preliminary actions by automatically extending and positioning the side view mirrors before the hitching operation is completed. The controller detects when the vehicle is approaching a trailer and proactively adjusts the mirrors to the trailering position, eliminating the need for manual adjustment during the hitching process.
Solution Approach 2:
The mirror adjustment system serves itself by using the vehicle's existing detection systems (camera, radar) to identify trailer approach and automatically controlling the mirror actuators. The system monitors its own operational context and self-adjusts without external manual input, making the mirror adjustment process autonomous.
2Productivity
If automatic mirror adjustment system is implemented, then the hitching process is simplified and time is reduced, but the device complexity increases
Solution Approach 1:
The system achieves multi-functionality by utilizing the vehicle's existing detection devices (camera, radar) for dual purposes: their original function for obstacle detection and the new function for triggering mirror adjustment. The controller also manages multiple functions including mirror extension, positioning, and coordination with the hitching system, reducing the need for separate dedicated components.
Solution Approach 2:
The patent merges the mirror adjustment function with the existing hitching detection and control systems. The controller integrates mirror control with the automatic hitching system, combining what could be separate systems into a unified control architecture that shares sensors, processing logic, and actuation resources.
