CMS Side Display View Switching for Blind-Spot Lane Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera monitoring systems (CMS) in vehicles have limitations in providing a comprehensive view of the surrounding environment, particularly in blind spots, which can lead to difficulties for drivers during lane changes or turns, and require additional manual actions for information retrieval, posing safety risks.
Innovation Solution
An electronic device that uses a CMS to detect lane change signals and switch the displayed view from a side camera image to a top-view image, overlaying the side camera image on the top view, and providing a lane change user interface with information about lane change feasibility, using external and internal cameras, sensors, and gesture inputs to enhance driver awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the CMS side display shows only the surrounding environment image captured by the external camera, then the system is simple and easy to operate, but the driver cannot check blind spots and make accurate driving judgments
Solution Approach 1:
The patent combines the external camera image and internal camera image into a single composite display. The external camera captures the surrounding environment while the internal camera captures the driver's state, and both are merged into one view displayed on the CMS side display, providing comprehensive information without requiring separate display systems
Solution Approach 2:
The CMS side display is designed to serve multiple functions: displaying surrounding environment images, showing driver monitoring images, providing blind spot notifications, and enabling touch-based lane change control. This multi-functional approach eliminates the need for separate systems for each function
2Loss of information
If the CMS side display requires touch input or button manipulation to determine surrounding environment information, then the system provides detailed information, but it creates safety risks during driving
Solution Approach 1:
The system uses the driver's own gestures (hand movements) to control the display functions. The internal camera detects the driver's hand gestures, and the system automatically responds by switching between different display modes (external camera view, internal camera view, lane change UI), eliminating the need for separate control inputs
Solution Approach 2:
The internal camera acts as an intermediary between the driver and the display system. Instead of requiring direct touch or button manipulation, the driver's gestures are captured by the internal camera and translated into control commands, providing a safer intermediate interaction method
3Ease of operation
If the CMS side display provides only presence/absence notification of surrounding vehicles, then the system is simple to operate, but the driver cannot make detailed driving judgments in specific situations
Solution Approach 1:
The display content dynamically changes based on the driver's gestures and driving conditions. The system transitions between different display modes (external camera image, internal camera image, lane change UI) in response to detected gestures, providing appropriate information at the right time without overwhelming the driver with constant complexity

AI summary
A method, performed by an electronic device installed in a vehicle, of switching a view of an image displayed on a camera monitoring system (CMS) side display, and an electronic device are provided. The disclosure includes an electronic device for displaying, on a camera monitoring system (CMS) side display, a first image representing a surrounding environment image, detecting a lane change signal of the vehicle, and, in response to the detected lane change signal, switching the first image displayed on the CMS side display to a second image representing a top view image showing locations of the vehicle and a surrounding vehicle in a virtual image as looking down from above the vehicle, and displaying the second image, and displaying a lane change user interface (UI) indicating information about whether a lane change is possible on the second image, and an operation method thereof.
