Motorcycle Emergency Voice Link via Driver Mobile Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency call systems for single-track vehicles, such as motorcycles, struggle to establish a reliable voice connection with the driver after an accident, especially if the driver is thrown from the vehicle or in noisy environments, as they rely solely on vehicle-integrated telematics units which may be damaged or inaccessible.
Innovation Solution
A method utilizing a telematics unit on the vehicle to transmit emergency call signals and establish a separate, independent voice connection with the driver's mobile radio device, such as a cellular phone, using various communication standards like GSM, WLAN, or Bluetooth, allowing for priority data transmission and secure, redundant communication channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a vehicle-integrated telematics unit is used for emergency calls, then automatic emergency call transmission is improved, but reliability of voice connection deteriorates when driver is thrown from vehicle or in noisy environments
Solution Approach 1:
The patent introduces a mobile radio device (smartphone) as an intermediary communication channel between the driver and emergency call center. When the driver is thrown from the vehicle or in noisy environments, the emergency call center can still establish voice connection through the mobile device carried by the driver, rather than relying solely on the vehicle's telematics unit.
Solution Approach 2:
The patent changes the communication parameter from vehicle-integrated only to dual-channel (vehicle telematics + mobile device). This allows the system to adapt to different scenarios: using the telematics unit for automatic data transmission and the mobile device for reliable voice connection, regardless of driver position or environmental conditions.
2Extent of automation
If only vehicle-integrated communication is used, then data transmission is automated, but ease of operation deteriorates when driver is unavailable at vehicle
Solution Approach 1:
The mobile radio device serves multiple functions: it acts as a backup communication channel, a voice connection medium, and a driver contact point. This multi-functional approach ensures that whether the driver is at the vehicle, thrown from it, or inaccessible, the emergency call center can still establish reliable communication.
3Reliability
If redundant communication channels are added, then reliability is improved, but device complexity increases
Solution Approach 1:
The system uses the driver's own mobile radio device (smartphone) as the redundant channel, eliminating the need for additional dedicated hardware. The mobile device already exists in the driver's possession and provides the needed communication capability without requiring complex additional installation.

AI summary
To establish a voice connection between the driver of a single-track vehicle and an emergency call center, a telematics unit is provided on the vehicle which transmits emergency call signals to the emergency call center. The voice connection is established between the driver and the emergency call center by way of the telematics unit and a mobile radio device carried by the driver of the vehicle.
