Vehicle Emergency Call Device Parallel Data Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle emergency call devices experience delays in transmitting emergency calls to the emergency call center due to the time required to collect additional information, which increases with the volume and types of information needed to grasp the vehicle's emergency situation accurately.
Innovation Solution
A vehicle emergency call device that determines the emergency call condition in parallel with collecting additional information, allowing the emergency call to be transmitted immediately while still reporting detailed information about the vehicle's situation, by using a condition determination portion, an emergency call portion, and an additional information collecting portion to connect to the emergency call center and gather data simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional information is collected from various sensors to enable the emergency call center to grasp more detailed emergency situation, then the precision of emergency support is improved, but the time required to collect information increases causing delay in emergency call transmission
Solution Approach 1:
The system performs preliminary actions by determining the emergency call condition (such as collision detection) before initiating the information collection process. When an emergency condition is detected, the system immediately triggers both the emergency call transmission and the additional information collection simultaneously, rather than collecting all information first. This preliminary detection and immediate response mechanism resolves the contradiction by ensuring the emergency call is initiated without delay while still gathering necessary detailed information during the call establishment phase.
2Loss of information
If the system waits to collect all additional information before transmitting the emergency call, then complete information is reported, but the emergency call transmission is delayed
Solution Approach 1:
The system implements continuity of useful action by making the emergency call transmission and additional information collection occur simultaneously and continuously. The emergency call is initiated immediately when the emergency condition is determined, and the additional information collection proceeds in parallel without interrupting or delaying the call transmission. This continuous parallel operation ensures both complete information reporting and timely transmission are achieved.
3Speed
If the emergency call condition determination is performed before collecting additional information, then the emergency call can be initiated promptly, but the detailed emergency situation information may be incomplete
Solution Approach 1:
The system performs preliminary determination of the emergency call condition (such as collision detection via acceleration sensor) to enable prompt emergency call initiation. This preliminary action triggers the emergency response immediately. Simultaneously, the system initiates additional information collection from various sensors (seatbelt status, airbag deployment, vehicle location) in parallel with the call transmission, ensuring detailed emergency situation information is gathered without compromising the speed of call initiation.

AI summary
A vehicle emergency call device equipped to a vehicle includes a condition determination portion determining whether an emergency call condition is satisfied, an emergency call portion transmitting an emergency call to an emergency call center by connecting a communication line with the emergency call center when the condition determination portion determines that the emergency call condition is satisfied, and an additional information collecting portion collecting, from the vehicle, additional information which indicating more detailed emergency situation of the vehicle. When the condition determination portion determines that the emergency call condition is satisfied, the emergency call portion connects the communication line with the emergency call center in parallel with collecting of the additional information by the additional information collecting portion.
