Solution Overview

Problem

Existing camera monitoring systems in vehicles do not provide adequate visibility for passengers, particularly when they are leaving the vehicle, as they are primarily designed for the driver's viewpoint, leading to potential safety hazards.

Innovation Solution

A display system that includes a video acquisition unit, a display unit, and a control unit, which switches to a passenger view mode when a passenger is predicted to leave the vehicle, improving visibility by adjusting the display mode to enhance the passenger's field of view.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single camera monitoring system is installed, then the system complexity is reduced, but it cannot provide adequate visibility for both driver and passenger simultaneously

Engineering Contradiction:
Improvesystem complexityVSAvoidpassenger visibility
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

A single camera monitoring system is designed to perform multiple functions by switching between driver view mode and passenger view mode. The same monitor and camera setup serves both the driver's needs during operation and the passenger's needs when preparing to exit, eliminating the need for separate monitoring systems for each user

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system dynamically adapts its display characteristics based on the current mode. The monitor housing angle and video display range are adjusted according to whether the system is in driver view mode or passenger view mode, allowing one system to provide adequate visibility for different users at different times without requiring multiple fixed installations

Inventive Principle:
Principle #15Dynamics

2Reliability

If the monitor is positioned for optimal driver viewing, then the driver can monitor the rear scene effectively, but the passenger must strain to view the same display when exiting

Engineering Contradiction:
Improvedriver monitoring reliabilityVSAvoidpassenger exit safety
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The display system switches between static configurations optimized for different users. When in driver view mode, the monitor positioning ensures reliable rear scene monitoring for the driver. When switching to passenger view mode, the system adjusts the display parameters to ensure the passenger can safely view the rear scene before exiting, with the transition triggered by detected conditions such as door unlock signals or seatbelt unbuckling

Inventive Principle:
Principle #15Dynamics

AI summary

A display system includes a display provided in a vehicle to display a video captured by a camera provided in the vehicle to capture a scene around the vehicle, and a controller that switches, when it is predicted that a passenger of the vehicle will leave the vehicle, a mode of the display system from a first mode to a second mode. In the first mode, the controller clips a first video in a first area from a video frame captured by the camera and outputs the first video to the display. In the second mode, the controller clips a second video in a second area from the video frame captured by the camera and outputs the second video to the display. The second area is different from the first area.
