Vehicle-to-Vehicle Emergency Call System for Network-Independent Rescue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle emergency call systems rely on remote communication capabilities and human intervention, which can fail in severe accidents due to network quality issues and injury, leading to delayed or ineffective rescues.
Innovation Solution
A vehicle-to-vehicle communication system using near-field communication to broadcast emergency calls, independent of remote network quality and human representation, with accident severity levels and response messaging to ensure timely rescue actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If point-to-point communication with PSAP is used, then rescue coordination is possible, but rescue efficiency is restricted by public safety answering point workload and queue priority
Solution Approach 1:
The patent segments the rescue response system into multiple independent vehicles with communication capabilities, rather than relying on a single centralized PSAP. Each vehicle can independently receive emergency calls and provide assistance, creating a distributed rescue network that bypasses PSAP workload limitations.
Solution Approach 2:
Nearby vehicles autonomously detect and respond to emergency calls without requiring PSAP coordination. The system enables self-organizing rescue where receiving vehicles automatically navigate to the emergency location and provide assistance, eliminating the bottleneck of human-operated PSAP queues.
2Reliability
If LTE remote communication is required, then long-distance rescue coordination is possible, but communication fails in severe accidents due to network quality issues
Solution Approach 1:
The patent introduces vehicle-to-vehicle communication as an intermediary layer between the emergency vehicle and distant infrastructure. This direct peer-to-peer communication channel bypasses the need for LTE network infrastructure, enabling reliable communication in environments where remote networks are unavailable or degraded.
3Loss of information
If human intervention is required for accident statement, then accurate information can be provided, but rescue is delayed or missed when the person is injured
Solution Approach 1:
The patent implements preliminary automatic detection of accident conditions through vehicle sensors (collision detectors, airbag status, abnormal motion detection). This preliminary action captures accident information automatically before human intervention is needed, eliminating the delay caused by injured persons being unable to communicate.
Solution Approach 2:
The emergency call system operates autonomously without requiring human initiation or information provision. The vehicle's communication system automatically detects the emergency state, formulates the emergency call message, and transmits it to nearby vehicles, completely removing the human-in-the-loop requirement for information accuracy.
4Reliability
If eCall system continuous operation is required, then remote rescue coordination is possible, but the system cannot work after physical damage in severe accidents
Solution Approach 1:
The patent uses nearby vehicles as intermediary carriers for emergency information. Instead of requiring the damaged vehicle's eCall system to remain operational for the entire rescue coordination, the emergency call message is immediately transmitted to and carried by nearby intact vehicles, which then provide assistance.

AI summary
A first communications device is provided. The first communications device is disposed in a first vehicle, and the first communications device includes: a first information processing unit, where the first information processing unit obtains first status information of the first vehicle; determines, based on the first status information, whether a vehicle accident occurs; and generates a first emergency call message when determining that the vehicle accident has occurred, where the first emergency call message includes a first accident level; and a first vehicle-to-vehicle communications unit, where the first vehicle-to-vehicle communications unit is coupled to the first information processing unit, and the first vehicle-to-vehicle communications unit receives the first emergency call message from the first information processing unit, and sends the first emergency call message in a first range around the first vehicle. A corresponding second communications device is further provided, and the second communications device sends a rescue response message in response to an emergency call message.
