Vehicle E-Call Trigger Using Travel Data and Sensor Fusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency call systems for vehicle accidents face challenges in detecting accidents when drivers lose consciousness or airbags do not deploy properly, leading to difficulties in requesting emergency assistance.
Innovation Solution
An apparatus and method that utilize travelling information, such as gear state and vehicle speed, to detect accidents and automatically transmit an emergency call signal, including collision detection using cameras, radars, and acceleration sensors, to ensure timely and accurate emergency call requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an emergency rescue button is used to request emergency assistance, then the system can transmit accident information to a center, but the driver cannot request help when losing consciousness or when the button is inaccessible
Solution Approach 1:
The system automatically detects accidents using sensors (airbag deployment sensor, collision sensor, sudden brake sensor) and transmits emergency call information without requiring manual driver input. The E-Call module monitors vehicle parameters and autonomously determines when an accident has occurred, enabling the system to serve itself in the emergency call request process.
Solution Approach 2:
The manual mechanical button operation is replaced with automated sensor-based detection systems. The system uses electronic sensors to detect accident conditions (airbag deployment, collision forces, sudden braking) and automatically triggers the emergency call transmission, substituting the mechanical button press with electronic detection and automated control.
2Reliability
If multiple sensors are combined to improve detection reliability, then the system can detect accidents more reliably, but the device complexity increases
Solution Approach 1:
The E-Call module serves multiple functions: it monitors airbag deployment, detects collisions, identifies sudden braking events, and automatically transmits emergency call information. By designing a universal system that performs multiple detection and response functions through a single integrated module, the patent reduces overall system complexity while maintaining high detection reliability through the combination of multiple sensor inputs.
