Vehicle Emergency Reporting System Communication Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic emergency reporting systems for vehicles face challenges in accurately transmitting emergency information due to unreliable communication status and limited base station coverage, leading to potential delays or inaccuracies in emergency response.
Innovation Solution
The system includes a determiner to assess communication quality, a normality transmitter to send rich information during satisfactory communication, and an emergency transmitter to send both emergency and rich information when the communication is satisfactory, while prioritizing emergency information transmission when the status is unsatisfactory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If rich information is transmitted during normal operation, then information completeness is improved, but communication time and energy consumption increase
Solution Approach 1:
The system pre-processes and categorizes information into essential and non-essential types before emergency occurrence. During normal operation, only essential information is transmitted, while non-essential information is stored for potential emergency transmission, thus avoiding unnecessary communication time and energy consumption during normal states
Solution Approach 2:
The transmission mode dynamically switches between normal mode (transmitting only essential information) and emergency mode (transmitting both essential and non-essential information). This dynamic adaptation allows the system to optimize communication efficiency during normal operation while ensuring complete information transmission when emergencies occur
2Speed
If emergency information is transmitted quickly, then response time is improved, but information accuracy may deteriorate due to communication errors
Solution Approach 1:
The system transmits essential information first to ensure rapid response, then transmits non-essential information to complete the data set. This partial transmission approach ensures that critical emergency information reaches the server quickly even if communication conditions are poor, while still providing complete information when possible
Solution Approach 2:
The system monitors communication quality in real-time and adjusts transmission strategies accordingly. When communication quality is poor, the system prioritizes transmitting essential information and may retry non-essential information transmission, thus balancing speed and reliability based on actual communication conditions
3Speed
If communication protocols are simplified for emergency transmission, then transmission speed is improved, but information completeness deteriorates
Solution Approach 1:
The information is segmented into essential and non-essential categories. Essential information is transmitted using simplified protocols for speed, while non-essential information is transmitted using complete protocols when communication conditions allow, thus balancing transmission speed and information completeness
Solution Approach 2:
The protocol selection dynamically adapts based on communication quality and emergency severity. In severe emergencies with poor communication conditions, only essential information is transmitted using simplified protocols. When communication conditions improve, the system switches to complete protocols to transmit all information, thus optimizing the balance between speed and completeness

AI summary
An automatic emergency reporting system for a vehicle includes a determiner, a normality transmitter, a detector, and an emergency transmitter. The determiner determines a quality of communication between a communication terminal of the vehicle and a server. The normality transmitter transmits rich information available in the server from the communication terminal in a normal state. The detector detects an emergency of the vehicle. The emergency transmitter transmits emergency information from the communication terminal to the server after the detection. The emergency transmitter transmits the rich information with the emergency information in response to the detection of the emergency of the vehicle in a state in which a status of the communication with the server is satisfactory. The emergency transmitter transmits the emergency information in response to the detection of the emergency of the vehicle in a state in which the status of the communication with the server is not satisfactory.
