Electronic Mirror System Automatic Mode Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic mirror systems require occupants to manually switch modes each time transitioning from reverse driving to forward driving, leading to frustration as the system reverts to standard mode, necessitating frequent operation of a switch to access wide-angle views.
Innovation Solution
An electronic mirror system with an imaging section, display section, selection section, operation section, and display control section that allows automatic switching between standard, wide-angle, and reverse driving modes, maintaining the previously set mode when switching from reverse to forward driving, and optionally displaying an image with a larger vertical magnification ratio for reverse driving to maintain a consistent aspect ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mode returns to standard mode when switching from reverse driving to forward driving, then the system maintains a simple default state, but the occupant must manually operate a switch each time to access wide-angle mode, causing frustration
Solution Approach 1:
The system performs preliminary action by storing the selected mode (standard or wide-angle) in memory before reverse driving occurs. When transitioning from reverse to forward driving, the system automatically restores the previously stored mode without requiring manual intervention, thus resolving the contradiction between ease of operation and system complexity.
Solution Approach 2:
The system implements feedback by detecting the shift position change from reverse to forward driving and automatically responding by restoring the previously selected mode. This closed-loop control eliminates the need for manual switching while maintaining simple default behavior, balancing ease of operation with controlled system complexity.
2Loss of time
If the system automatically switches between standard and wide-angle modes based on driving direction, then frequent manual switching is eliminated, but the system complexity increases requiring memory and control logic
Solution Approach 1:
The system performs preliminary action by storing the selected mode (standard or wide-angle) in memory before reverse driving occurs. When transitioning from reverse to forward driving, the system automatically restores the previously stored mode without requiring manual intervention, thus resolving the contradiction between ease of operation and system complexity.
Solution Approach 2:
The system performs self-service by automatically detecting the driving direction change and restoring the appropriate mode without external intervention. The control section autonomously manages the mode switching based on shift position detection, eliminating time loss while keeping the control logic relatively simple.
3Adaptability or versatility
If the imaging range is changed between first imaging range and second imaging range, then the display can adapt to different viewing needs, but the device complexity increases with additional imaging sections
Solution Approach 1:
The system achieves adaptability by changing the imaging range parameter between a first imaging range (narrower, standard view) and a second imaging range (wider, wide-angle view). The imaging section captures images at different ranges, and the display control section selectively displays the appropriate range based on the selected mode, providing versatility without requiring physically different imaging devices.
Solution Approach 2:
The imaging section is designed with multi-functionality to capture images in both the first and second imaging ranges. This universal imaging capability allows the same hardware to serve multiple viewing needs (standard and wide-angle modes), reducing device complexity while maintaining high adaptability.

AI summary
A display system includes an imaging section, a display section, a selection section, an operation section, and a display control section. The imaging section is configured to image toward a rear and a side of a vehicle. The display section is configured to display an image captured by the imaging section. The selection section is configured to allow selection of a standard mode or a wide-angle mode. The operation section is configured to enable operation of one out of forward driving or reverse driving of the vehicle. The display control section includes RAM, and switches to whichever mode has been set out of the standard mode or the wide-angle mode immediately prior to the vehicle being driven in reverse in cases in which an operation to switch from reverse driving to forward driving of the vehicle has been performed using the operation section while in a reverse driving mode.
