Inter-Vehicle Image Saving for Sudden Deceleration Events
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle exterior image saving systems only capture and save images from the viewpoint of a subject vehicle that has suddenly decelerated, failing to provide images from the perspective of other vehicles.
Innovation Solution
A vehicle exterior image saving system and inter-vehicle communication apparatus that allow a first vehicle to capture and save images of a second vehicle's forward direction using an imaging apparatus in the first vehicle, with inter-vehicle communication to determine sudden deceleration and transmit image-saving instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system only saves images from the subject vehicle's own camera, then the device complexity is reduced, but the reliability of obtaining comprehensive exterior images is insufficient
Solution Approach 1:
The patent combines imaging apparatus from multiple vehicles (first vehicle and second vehicle) to capture images of the same target area. The saving section integrates images from different viewpoints into a composite set, merging resources to achieve comprehensive coverage that a single vehicle cannot provide alone.
Solution Approach 2:
The imaging apparatus in the first vehicle serves dual purposes: capturing images for its own drive recorder function and capturing images of the second vehicle's forward direction for enhanced exterior image saving. This multi-functional use of existing apparatus increases reliability without adding dedicated new devices.
2Quantity of substance
If the system uses inter-vehicle communication to share image data, then the quantity of available exterior images is increased, but the loss of time for communication and coordination increases
Solution Approach 1:
The first vehicle's imaging apparatus continuously captures and stores images in advance, preparing them for potential sharing before any accident occurs. When the second vehicle experiences sudden deceleration, the pre-captured images are immediately available for transmission without requiring real-time capture during the critical moment.
Solution Approach 2:
The system transmits only the specific image data that is needed (images of the second vehicle's forward direction) rather than transferring complete image sets or undergoing extensive coordination protocols. This selective data transmission rushes through the communication process efficiently, minimizing time loss.
3Area of stationary object
If the system captures images from multiple vehicles, then the coverage area is expanded, but the difficulty of detecting and measuring which images to save increases
Solution Approach 1:
The saving section uses feedback from the sudden deceleration detection to automatically determine which images to save. When the second vehicle's deceleration is detected, the system receives feedback information about the event and automatically selects images from the first vehicle that correspond to the second vehicle's forward direction, eliminating manual selection difficulty.
Solution Approach 2:
The system focuses on saving only the specific portion of images that have local quality relevant to the accident - namely, images showing the second vehicle's forward direction. Rather than saving all captured images uniformly, the system selectively preserves only those with specific directional quality needed for accident reconstruction.

AI summary
Vehicle exterior images are captured sequentially by an imaging portion of an imaging-equipped mobile terminal used in a first vehicle and stored temporarily in an image temporary-storage portion in the first vehicle. The first vehicle receives vehicle information from a second vehicle different from the first vehicle, through inter-vehicle communication. When it is determined that a sudden deceleration arises in the second vehicle based on the vehicle information received by the first vehicle, the vehicle exterior images stored in the image temporary-storage portion are read and saved in a memory.
