Integrated Driver Display Switching for Vehicle Camera Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The proliferation of displays in camera monitor systems (CMS) due to added cameras increases information assimilation challenges for vehicle operators, making it difficult to fully utilize additional views and enhance visibility.
Innovation Solution
A method and apparatus that integrates a camera monitor system (CMS) with a driver information display (DIS) by swapping vehicle operating information with captured images from multiple display areas in response to triggering events, using domain controllers connected via a vehicle data bus and a direct cable for video data communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If more cameras and displays are added to increase the viewable area, then operator visibility is improved, but device complexity and information management difficulty increase
Solution Approach 1:
The patent combines the CMS and DIS into a single integrated system where the camera monitor functionality is merged with the driver information display. This consolidation reduces the total number of separate displays while maintaining enhanced visibility through strategic display of camera feeds within the integrated interface.
Solution Approach 2:
The integrated display serves multiple functions: it displays vehicle operating information, shows camera feeds from multiple angles, and provides contextual information about detected objects. This multi-functionality eliminates the need for separate dedicated displays for each function, reducing overall system complexity.
2Reliability
If more cameras and displays are added to increase the viewable area, then blind spots are reduced, but information assimilation becomes more challenging
Solution Approach 1:
The system employs an object detection module as an intermediary that processes camera feeds and identifies relevant objects, then presents this processed information to the operator. This intermediary layer filters and organizes raw visual data into meaningful information about detected objects, making it easier for operators to assimilate critical information without being overwhelmed by raw camera feeds.
Solution Approach 2:
The system provides feedback to the operator by detecting objects in camera feeds and displaying relevant information about these objects on the integrated display. This feedback mechanism helps operators understand what is happening in the camera views without requiring them to continuously analyze raw video streams, thereby improving information assimilation.
3Reliability
If vehicle operating information is continuously displayed, then operator awareness of vehicle status is maintained, but distractions increase when camera feeds need to be shown
Solution Approach 1:
The display configuration is dynamic rather than static. The system automatically adjusts what information is displayed based on detected triggering events such as object detection or camera activation. This dynamic reconfiguration allows the display to maintain vehicle status information during normal operation while seamlessly transitioning to show camera feeds when relevant events occur, minimizing operator distraction.
Solution Approach 2:
The system prepares for potential camera feed display by having the integrated display architecture ready to switch between vehicle status information and camera feeds. When a triggering event is detected, the transition is already prepared and executes smoothly, preventing operator distraction that would result from abrupt or poorly timed display changes.

AI summary
A method of providing views in a camera monitor system (CMS) for a vehicle include a) depicting vehicle operating information from a first controller onto a driver information display (DIS), the depicting step includes showing at least one of a vehicle speed, an engine rotational speed, fuel level, engine temperature, and gear position indicator, b) capturing an image from a field of view and providing the captured image to a second controller, c) detecting a triggering event relating to the captured image, d) sending the captured image from the second controller to the first controller in response to the triggering event, and e) altering the depicted vehicle operating information on the DIS with the first controller to show the captured image.
