Vehicle Call Reconnection Using Pre-Acquired Passenger IDs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to enable continuous communication with passengers after they leave a vehicle following an accident, hindering quick responses from call centers.
Innovation Solution
An information processing device in a moving body that uses short-range wireless communication to acquire identification information from portable terminals, detects accidents, and transmits this information to a server for reconnection with the passenger's device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operator calls back to the on-board device when the passenger has left the vehicle, then the calling system attempts to re-establish contact, but the communication fails because the passenger is no longer present at the on-board device
Solution Approach 1:
The system performs preliminary action by acquiring and storing identification information from the portable terminal before an accident occurs. When an accident is detected, the system can immediately transmit this pre-acquired identification information to the server apparatus, enabling rapid reconnection without waiting for the passenger to return to the on-board device. This resolves the contradiction by preparing communication credentials in advance, ensuring both reliability and speed of response.
Solution Approach 2:
The system introduces an intermediary approach by using identification information from the portable terminal as a mediator to re-establish communication. Instead of directly calling the on-board device (which the passenger has left), the system transmits the passenger's identification information to the server, which then enables communication through the portable terminal. This intermediary mechanism ensures reliable communication regardless of the passenger's physical location.
2Ease of operation
If the system only uses the on-board device for communication, then the communication channel is fixed and simple, but the system cannot communicate with passengers who have left the vehicle
Solution Approach 1:
The system applies universality by enabling communication through multiple devices - both the on-board device and the passenger's portable terminal. The identification information acquisition module allows the system to work with portable terminals, while the existing infrastructure continues to use on-board devices. This multi-functional capability ensures communication accessibility regardless of which device the passenger is using, without significantly increasing overall system complexity.
Solution Approach 2:
The system performs preliminary action by pre-acquiring identification information from portable terminals and storing it for future use. This preparation allows the system to quickly switch to alternative communication channels when needed, improving accessibility without adding complex real-time decision-making mechanisms. The pre-stored identification information enables seamless transition between communication devices.
