Electronic Mirror Display Control for Rear and Cabin View Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic mirrors that display images from rear-mounted cameras do not provide a comprehensive view of the vehicle's interior and exterior, requiring drivers to switch between cameras or turn back to check the rear seat, which is inconvenient and distracting.
Innovation Solution
A display control system with dual imaging units for the vehicle's exterior and interior, integrated with a display unit and control unit to simultaneously display both images based on predetermined conditions, allowing seamless switching and aspect adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple cameras are mounted to capture both rear side and interior images, then comprehensive coverage is achieved, but the driver finds it troublesome to switch between cameras
Solution Approach 1:
The patent merges multiple camera views into a single integrated display. The display control unit processes images from both the rear exterior camera and interior camera, presenting them together on one display unit. This eliminates the need for the driver to manually switch between separate camera views, as both are simultaneously available in one location.
Solution Approach 2:
The display control unit dynamically adjusts what is shown on the display based on vehicle conditions (running state, stop state, driver presence). The system automatically changes between displaying rear images, interior images, or both together, providing adaptive operation that reduces manual switching while maintaining comprehensive monitoring capability.
2Device complexity
If the electronic mirror displays only rear side images, then the display content is simple, but the driver cannot easily ascertain the interior state of the vehicle
Solution Approach 1:
The display control unit provides multiple display modes within a single system. It can display rear images alone, interior images alone, or both together, depending on the situation. This multi-functional capability allows the system to maintain simplicity when needed while providing comprehensive information when required, without requiring separate display devices for different functions.
Solution Approach 2:
The system dynamically changes its display content based on vehicle state and driver needs. When the vehicle is stopped or when interior monitoring is needed, the display control unit automatically includes interior images in the display output. This dynamic adaptation allows the system to provide comprehensive information without permanently increasing display complexity.

AI summary
A display control system (100) includes a first imaging unit (20), a second imaging unit (30), a display unit (10), and a display control unit (41). A first imaging unit (20) images a rear side of a mobile body. A second imaging unit (30) images the inside of the mobile body. The display unit (10) is located at a position visually recognizable to a driver of the mobile body. A display control unit (41) displays at least one of a first image (21) generated by using a first imaging unit (20) or a second image (31) generated by using a second imaging unit (30) on a display unit (10). A display control unit (41) changes a display aspect of at least one of the first image (21) or the second image (31) according to a predetermined state, and displays both the first image (21) and the second image (31) on a display unit (10) in a case where the predetermined state satisfies a first condition.
