Vehicle Mirror Adjustment for Consistent Driver Field of View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle mirrors do not automatically adjust to maintain a consistent field of view as the driver changes position, leading to potential blind spots and reduced safety.
Innovation Solution
A vehicle computing device dynamically adjusts the orientation of mirrors based on the driver's position by determining reference orientations at different seat positions and interpolating between them to maintain a similar field of view, using sensors and a graphical user interface for driver input and calibration data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver manually adjusts mirror position for each seat position change, then the field of view can be optimized, but the operation complexity and time consumption increase
Solution Approach 1:
The system automatically detects driver position changes via seat position sensors and autonomously calculates and adjusts mirror orientations without requiring manual driver intervention. The computing device retrieves calibration data, determines optimal mirror positions, and executes adjustments automatically, making the system self-serving.
Solution Approach 2:
The system continuously monitors seat position through sensors and uses this feedback to trigger mirror adjustments. The closed-loop feedback mechanism ensures the mirror position is dynamically updated based on real-time driver position data, maintaining optimal field of view consistency.
2Measurement precision
If the system stores calibration data for multiple reference positions, then mirror adjustment accuracy improves, but the device complexity and data storage requirements increase
Solution Approach 1:
The system performs preliminary calibration by storing pre-determined mirror orientations for multiple reference seat positions in a database. This advance preparation allows the system to quickly retrieve and apply appropriate calibration data during operation without real-time computation, improving accuracy while managing complexity through pre-processing.
Solution Approach 2:
The system dynamically selects and applies the appropriate calibration data based on the current seat position. By interpolating between stored reference positions or selecting the nearest match, the system adapts mirror orientations dynamically to maintain accuracy across the full range of seat positions without requiring exhaustive real-time calculations.
3Reliability
If automatic mirror adjustment is implemented, then safety and visibility improve, but the system complexity and computational requirements increase
Solution Approach 1:
The computing device leverages existing multi-functional vehicle systems (seat position sensors, mirror actuators, and general-purpose computing hardware) to implement automatic mirror adjustment. By reusing existing components for multiple purposes, the system achieves safety improvements without proportionally increasing overall system complexity.

AI summary
In general, techniques are described by which a computing system dynamically and automatically adjusts an orientation of one or more mirrors of a vehicle. A computing system includes at least one processor and memory. The memory includes instructions that, when executed, cause the at least one processor to determine a current orientation of a mirror of a vehicle and determine a preferred orientation of the mirror based upon a set of data points. Execution of the instructions also causes the at least one processor to output a command to adjust the mirror to the preferred orientation in response to determining the current orientation is not the preferred orientation.
