Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional earthquake detection systems face challenges due to sparsity of sensing stations in areas with limited access to communication and power, leading to delayed warnings and inadequate safety measures for vehicles and occupants during earthquakes, especially in coastal regions where vehicles may be unaware of or unprepared for impending earthquakes.
Innovation Solution
Equipping personal automotive vehicles with electro-mechanical accelerometers, GPS navigation, and wireless communications to function as earthquake sensing nodes, enabling them to communicate with a centralized response system, receive early warnings, and automatically initiate safety measures such as power conservation and guidance for occupants, while also providing data for improved detection and response.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional specialized sensing systems are deployed, then detection accuracy is improved, but deployment cost and complexity increase significantly
Solution Approach 1:
The patent repurposes existing vehicle systems (accelerometers for navigation, GPS for positioning, wireless comms for communication) to serve dual purposes: their original functions plus earthquake detection. This eliminates the need for specialized sensing equipment while maintaining detection capability, directly resolving the contradiction between detection accuracy and system complexity
Solution Approach 2:
Vehicles use their own onboard sensors and systems to detect and report earthquakes, rather than relying on dedicated sensing infrastructure. The vehicle's existing accelerometers and GPS serve the earthquake detection function without requiring additional specialized equipment, reducing deployment complexity while maintaining detection capability
2Area of stationary object
If sensing stations are deployed in areas with limited access, then detection coverage is improved, but power and communication availability worsen
Solution Approach 1:
Vehicles leverage their existing power supplies and communication systems to perform earthquake detection, eliminating the need for separate power and communication infrastructure at sensing locations. The vehicle's onboard systems already provide the necessary energy and connectivity, enabling deployment in remote areas without additional power constraints
Solution Approach 2:
The vehicle's power and communication systems serve multiple functions simultaneously: their primary vehicle operations plus earthquake detection and data transmission. This multi-functionality eliminates the need for dedicated power and communication infrastructure at sensing stations, resolving the contradiction between coverage area and power availability
3Loss of time
If warning time is increased, then response preparation is improved, but reaction time window for automatic measures decreases
Solution Approach 1:
The system pre-programs automatic safety measures and response protocols in advance, so that when an earthquake warning is received, pre-planned actions can be executed immediately without delay for human decision-making. This allows full utilization of the warning time window while maintaining rapid automatic response capability
Solution Approach 2:
The system continuously monitors vehicle status and environmental conditions, providing real-time feedback to the control system. This enables rapid automatic adjustment of safety measures based on current vehicle state, maximizing the utilization of the limited reaction time window while maintaining preparedness throughout the warning period
4Ease of operation
If vehicles continue driving during earthquake warning, then mobility is maintained, but safety risk increases
Solution Approach 1:
The system dynamically adjusts vehicle operation mode based on real-time earthquake risk assessment. When low risk is detected, normal driving continues; when high risk is detected, the system automatically transitions to safety modes such as pulling over or stopping. This dynamic adaptation resolves the contradiction by maintaining mobility when safe and protecting against harm when dangerous
Solution Approach 2:
The system continuously monitors earthquake warning levels and vehicle location relative to hazard zones, providing real-time feedback to adjust driving behavior. This feedback loop enables the vehicle to maintain mobility in safe conditions while automatically responding to hazardous conditions by reducing speed or stopping, resolving the contradiction between mobility and safety

AI summary
Methods and apparatus for automotive vehicles respond to earthquake warnings to provide occupant awareness of potential hazards while taking autonomous actions such as slowing the vehicle, navigating to a safe location, and providing safety advice. Data gathered by the vehicle can be sent wirelessly to a remote center for coordinating emergency response using the data. The vehicle preferably comprises a powertrain, a plurality of vehicle accessory systems, and an emergency management controller. The controller is adapted to receive an earthquake warning message. The controller responds to the warning message by providing a power conservation command to at least one accessory system to reduce power consumption by at least one respective noncritical accessory function. In addition, it evaluates a vehicle mobility status and automatically launches a corresponding safety measure.
