Vehicle Emergency Dialing System Using Wireless Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Emergency services cannot be provided if a vehicle's telematics unit is non-functional or unavailable, particularly in situations like vehicle crashes or rollovers.
Innovation Solution
A method and system that detect an emergency condition, determine if the telematics unit is unavailable, and initiate emergency communications using available wireless devices in the vehicle, prioritizing them based on power levels and availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If emergency communication is attempted using the vehicle telematics unit, then emergency services can be provided, but the system fails when the telematics unit is non-functional or unavailable
Solution Approach 1:
The patent introduces wireless devices (mobile phones, tablets, or other communication devices) as intermediary components to bridge the gap when the telematics unit fails. These devices serve as backup communication channels, allowing emergency services to be contacted through alternative means when the primary telematics-based communication path is unavailable.
Solution Approach 2:
The system prepares backup communication devices in advance and establishes their availability before an emergency occurs. The method detects telematics unit unavailability and automatically activates pre-identified wireless devices as a cushioning measure to ensure emergency communication capability is maintained even when the primary system fails.
2Reliability
If multiple wireless devices are used for emergency communication, then communication reliability improves, but power consumption increases
Solution Approach 1:
The system dynamically adjusts the communication strategy based on battery power levels. When power is充足, multiple wireless devices can be activated simultaneously to maximize communication reliability. When power becomes limited, the system transitions to using fewer devices or sequential activation to conserve energy, creating a dynamic balance between reliability and power consumption.
Solution Approach 2:
The patent changes the operational parameters of the communication system based on power availability. It monitors battery power levels and adjusts the number of active wireless devices, their activation sequence, and communication intensity accordingly. This parameter adjustment allows the system to optimize the trade-off between communication reliability and power consumption in real-time.
3Use of energy by moving object
If wireless devices are activated sequentially based on priority, then power consumption is reduced, but response time may be delayed
Solution Approach 1:
The system applies partial action by activating only the necessary number of wireless devices based on power availability and emergency severity. Rather than always activating all available devices simultaneously, it uses a prioritized approach where high-priority devices are activated first, and lower-priority devices are activated only if needed and power permits, thus reducing unnecessary power consumption while maintaining adequate response time.

AI summary
A system and method for providing emergency vehicle services is provided. The method includes detecting an emergency condition including a vehicle crash and/or rollover, determining if a vehicle telematics unit is available, and initiating an emergency communication using one or more wireless devices present in the vehicle if the vehicle telematics unit is unavailable.
