Electronic Mirror Switch Unit Multi-Function Mode Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of switches required for electronic mirror systems in vehicles poses a challenge, as existing systems need to incorporate additional functions beyond conventional optical side mirrors, leading to clutter and difficulty in adding more switches to the instrument panel, steering wheel, and doors.
Innovation Solution
An electronic mirror system with a camera, display unit, and a switch unit that includes an adjustment switch, an LR switch, a camera storage switch, and a multi-function switch, where the multi-function switch allows for mode transitions based on vehicle state, enabling adjustment of camera settings and display parameters without the need for separate switches for each function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional switches are added to the instrument panel, door, or steering wheel to support electronic mirror system functions, then the system can perform required functions (system startup, image quality adjustment, etc.), but the number of switches increases leading to clutter and difficulty in adding more switches
Solution Approach 1:
The patent applies multi-functionality by enabling existing switches (adjustment switch, LR switch, camera storage switch) to perform multiple functions. The control unit determines the operation to be executed based on the current state and combines multiple operations into a single switch operation sequence, allowing one switch to control multiple electronic mirror system functions without adding physical switches
2Ease of operation
If multiple separate switches are provided for each function (adjustment, LR switching, camera storage), then each function can be controlled independently, but the switch unit becomes complex and cluttered
Solution Approach 1:
The patent merges multiple separate switches into a unified switch unit where the adjustment switch, LR switch, and camera storage switch work together as an integrated system. The control unit combines the operations of these switches and executes multiple functions through a coordinated switch operation sequence, reducing physical clutter while maintaining operational independence
3Device complexity
If a multi-function switch is used to reduce the number of switches, then the switch unit becomes simpler, but the control logic becomes more complex to determine the correct operation based on vehicle state
Solution Approach 1:
The control unit automatically determines the appropriate operation to execute by monitoring the current vehicle state and interpreting the sequence of switch operations. The system self-adjusts by selecting from pre-stored operation sequences based on the detected state, eliminating the need for complex manual control logic while maintaining automated adaptability

AI summary
An electronic mirror system includes: a camera for capturing images of surroundings of a vehicle; a display unit for displaying an image captured by the camera; a switch unit including an adjustment switch and a multi-function switch; and a control unit for performing a process according to a signal from the switch unit. When the multi-function switch is operated, the control unit executes a process selected from a plurality of set processes according to a state of the vehicle; and in a case where the executed process is a transition to a mode for changing setting information of the system, and when the adjustment switch is operated after the transition, the control unit changes the setting information according to a signal from the adjustment switch.
