Vehicle Automatic Emergency Reporting with Backup Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic emergency reporting systems for vehicles face challenges in promptly acquiring accident information when the automatic reporting device malfunctions or is outside communication range, leading to delayed emergency responses.
Innovation Solution
The vehicle is equipped with a controller and display that automatically transmit emergency information to a server using a transmitter, and also displays destination information in a readable format for a communicator, such as a mobile terminal, allowing alternative communication paths when the primary transmitter fails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle uses only an automatic transmitter to send emergency information to the server, then the reporting process is fully automated, but the system becomes unreliable when the transmitter malfunctions or is outside communication range
Solution Approach 1:
The patent combines multiple communication methods (automatic transmitter and manual communicator) into a single emergency reporting system. The controller integrates both communication paths, allowing the system to switch between automatic and manual modes depending on which method is available, thereby improving reliability without requiring completely separate systems
Solution Approach 2:
The controller is designed to perform multiple functions: it can automatically transmit emergency information via the transmitter when communication is available, and alternatively display destination information on the display device for manual communication. This multi-functionality allows a single system to adapt to different communication scenarios and maintain reliability
2Reliability
If the vehicle displays destination information in a format readable by a communicator, then alternative communication paths are enabled, but the device complexity increases due to additional display and formatting components
Solution Approach 1:
The display device serves multiple purposes: it can display general vehicle information during normal operation and switch to displaying destination information in communicator-readable format during emergencies. This multi-functionality allows the same hardware to support both regular vehicle operations and emergency backup communication without requiring dedicated emergency-only components
Solution Approach 2:
The controller changes the display parameters (format, content, positioning) based on the communication mode. During emergencies, it transforms the destination information into a specific readable format suitable for manual communication, while during normal operation it displays standard vehicle information. This parameter adaptation allows flexible use of the display hardware
3Speed
If the system automatically transmits emergency information without manual intervention, then the response time is reduced, but the system fails when the transmitter is outside communication range or malfunctions
Solution Approach 1:
The controller prepares the destination information in advance in a communicator-readable format and displays it on the display device during normal operation or immediately when emergency is detected. This preliminary preparation ensures that when automatic transmission fails, the information is already formatted and ready for manual communication, enabling quick switching without delays
Solution Approach 2:
The display device acts as an intermediary between the controller and the external communicator. It transforms the emergency destination information into a visually readable format that can be manually communicated to emergency services, serving as a bridge when direct automatic transmission is unavailable

AI summary
A vehicle with an automatic reporting function includes a controller and a display. The controller is configured to control automatic transmission of emergency information to the server in a case of an emergency of the vehicle with a transmitter. The transmitter is configured to transmit the emergency information related to the emergency of the vehicle to a server configured to make a call for emergency action. The display is provided on the vehicle and configured to display destination information for the automatic transmission of the emergency information to the server in a format readable by a communicator different from the transmitter. The controller is configured to, in the case of the emergency of the vehicle, cause the display to display the destination information on the vehicle in the format readable by the communicator.
