Vehicle Caution Image Sharing for Pre-Arrival Hazard Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers are unable to adequately understand the situation of caution-needed spots in advance, limiting effective preventive driving.
Innovation Solution
A safe driving support system and method that utilizes a data center connected to vehicles equipped with detection and imaging devices to identify and store caution-needed spots, transmitting caution images to approaching vehicles for pre-arrival display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only position information of caution-needed spots is transmitted to drivers, then the notification system remains simple and easy to operate, but drivers cannot adequately understand the situation of caution-needed spots beforehand
Solution Approach 1:
The system transmits images captured by imaging devices at caution-needed spots to approaching vehicles. These images serve as visual copies that convey the actual situation at the caution-needed spot, enabling drivers to understand hazards without physically being present. This resolves the contradiction by providing comprehensive situational information through image copying rather than complex textual descriptions.
Solution Approach 2:
The system identifies and transmits images of caution-needed spots to approaching vehicles before they arrive at the location. By performing the information transmission in advance, drivers can understand the situation beforehand and prepare appropriate driving actions, resolving the information understanding issue while maintaining system simplicity through automated preliminary processing.
2Loss of information
If real-time images from detection devices are transmitted to all vehicles, then drivers receive complete situational information, but the communication network load and data transmission complexity increase significantly
Solution Approach 1:
The system transmits images only to vehicles that are approaching caution-needed spots, not to all vehicles universally. This localized information transmission approach ensures that each vehicle receives relevant information only when needed, reducing unnecessary network traffic and communication complexity while maintaining complete situational information for those who need it.
Solution Approach 2:
The system extracts and transmits only the specific images related to caution-needed spots from the continuous stream of data captured by imaging devices. By extracting only the relevant visual information rather than transmitting all captured data, the system provides complete situational information for hazards while minimizing communication network load and complexity.
3Reliability
If caution information is processed and transmitted to approaching vehicles, then drivers can perform preventive driving, but the processing time and response delay increase
Solution Approach 1:
The system performs preliminary identification and registration of caution-needed spots as vehicles pass by, storing image data and location information in advance. When another vehicle approaches the same spot, the pre-processed information can be quickly retrieved and transmitted without requiring real-time analysis, thus ensuring reliable preventive driving information while minimizing processing time delays.
Solution Approach 2:
The system establishes a database of caution-needed spots with pre-captured images and location data before they are needed by approaching vehicles. This beforehand preparation creates an information buffer that allows rapid response to approaching vehicles without real-time processing delays, maintaining both reliability and timely response.
Data Source
AI summary
In a safe driving support system, a data center is connected to a plurality of vehicles via a communication network. The data center stores a position of a first vehicle of which a G sensor detects that behavior of the vehicle has been disturbed when caution information is received from the first vehicle as a caution-needed spot in a storage device. The data center transmits data of a caution image extracted from data of images in a predetermined period before the caution information has been received out of the data of the images captured by a drive recorder of the first vehicle to a second vehicle approaching the caution-needed spot when the caution information is received. The display of the second vehicle having received the data of the caution image attracts attention by displaying the caution image before the second vehicle arrives at the caution-needed spot.
