Rear View Camera Switching for Open Twin Swing Doors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rear view cameras on vehicles with twin swing doors are ineffective when the doors are open, limiting the ability to monitor the rear area during reversing or parking, especially for special vehicles like delivery trucks or police vehicles.
Innovation Solution
Implementing a built-in camera on the vehicle's frame to capture rear views when the twin swing doors are open, integrated with an IVI system that switches to the built-in camera for image transmission based on door and gear states, and providing images to a display or personal terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rear camera is disposed on the twin swing door to provide rear view, then the rear view can be captured when the door is closed, but the rear view cannot be provided when the door is opened
Solution Approach 1:
The IVI system is designed to support multiple camera sources (rear camera on the door and built-in camera on the frame) and automatically selects the appropriate camera based on door state and gear position, making the system universally functional across different operating conditions
2Device complexity
If the rear camera is disposed near the handle or license lamp of the twin swing door, then the camera structure is simple, but the camera cannot capture rear view when the door is open
Solution Approach 1:
The IVI system acts as an intermediary that receives signals from both the rear camera and built-in camera, processes the door state and gear position information, and selectively switches between camera sources to ensure continuous rear view availability
Solution Approach 2:
The camera selection is dynamically adjusted based on real-time door state and gear position, allowing the system to switch between the simple rear camera installation and the built-in camera as needed

AI summary
A vehicle includes: a rear door configured to open and close a rear part of the vehicle; a gear switch implemented for manipulating a gear shift of the vehicle; a built-in camera disposed on a frame supporting the rear door and implemented to capture a rear view behind the vehicle; an in-vehicle infotainment (IVI) system configured to receive an image signal acquired by capturing the rear view behind the vehicle from the built-in camera, based on at least one of a state of a shift range indicated by the gear switch and an open or closed state of the rear door when a rear view mode is on; and a display device displaying a rear image signal provided from the IVI system. The rear view mode is an operation mode where the IVI system provides a rear view image of the vehicle.
