Vehicle Image Sharing Control Based on Speed and Distance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems fail to effectively display images in front of the vehicle itself or another vehicle based on speed and vehicle-to-vehicle distance, leading to inefficient image sharing and display.
Innovation Solution
A vehicle equipped with a camera unit, display unit, speed sensor, distance sensor, communication unit, and processor that determines its state based on speed and distance, displaying either its own captured image or images from another vehicle, depending on specific speed and distance conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the vehicle displays its own captured image, then the display shows accurate real-time information, but the system cannot provide extended field of view beyond the vehicle's own cameras
Solution Approach 1:
The patent combines image data from multiple sources - the vehicle's own cameras and cameras from other vehicles in the network - into a unified display system. This merging allows the system to provide both accurate real-time information from the vehicle itself and extended field of view from other vehicles, resolving the contradiction between information accuracy and adaptability.
Solution Approach 2:
The display unit is designed to serve multiple functions: displaying the vehicle's own captured images for accurate real-time information, and displaying images from other vehicles for extended field of view. This multi-functionality allows the same hardware to adapt to different information needs without compromising either accuracy or versatility.
2Adaptability or versatility
If the vehicle displays images from other vehicles, then the field of view is extended, but the system complexity increases due to image selection and switching logic
Solution Approach 1:
The system dynamically switches between displaying the vehicle's own images and images from other vehicles based on real-time conditions such as vehicle speed and distance to other vehicles. This dynamic adaptation simplifies the control logic by using clear, condition-based rules rather than complex decision-making algorithms.
Solution Approach 2:
The system pre-establishes switching criteria based on vehicle speed and distance parameters. By defining these conditions in advance, the system avoids complex real-time decision-making and simply executes predetermined switching logic when conditions are met, reducing overall system complexity.
3Measurement precision
If the vehicle continuously monitors speed and distance to determine image display, then the image display accuracy is improved, but the energy consumption increases
Solution Approach 1:
Instead of continuous monitoring, the system performs speed and distance measurements periodically at key decision points. This periodic action maintains sufficient measurement precision for determining when to switch images while significantly reducing energy consumption compared to continuous monitoring.
Solution Approach 2:
The system uses existing vehicle sensors and communication infrastructure to obtain speed and distance information needed for image switching decisions. By leveraging already-available data from the vehicle's own systems, the solution avoids additional energy-consuming measurement operations while maintaining accurate state determination.

AI summary
A vehicle configured to share a captured image with another vehicle, the vehicle including a first camera configured to capture the image; a first display; a second display; a speed sensor configured to sense a speed of the vehicle; a distance sensor configured to sense a vehicle-to-vehicle distance between the vehicle and a first vehicle immediately ahead of the vehicle; a transceiver configured to implement data communication between the vehicle and the first vehicle; and a processor configured to control the first camera, the first display, the distance sensor, the speed sensor and the transceiver. The processor is further configured to determine a state of the vehicle based on the speed of the vehicle and the vehicle-to-vehicle distance, display a first image captured by the first camera on the first display when the vehicle is in a first state, wherein the first state is a state in which the speed of the vehicle is equal to or greater than a first speed and less than a second speed, and the vehicle-to-vehicle distance is equal to or greater than a first distance and less than a second distance, display a second image captured by a second camera on the first display when the vehicle is in a second state, wherein the second state is a state in which the speed of the vehicle is equal to or greater than the second speed, and the vehicle-to-vehicle distance is equal to or greater than the second distance, and display the first image on the first display and the second image on the second display when the vehicle-to-vehicle distance is repeatedly increased and reduced within a predetermined time on the first distance or the second distance. In addition, the second camera is a camera installed in a second vehicle, the second vehicle being any one of one or more vehicles ahead of the vehicle.
