Vehicle Rescue Priority Determination From Standstill and Location Change
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency call systems lack objectivity in determining rescue priority, leading to subjective decisions based on occupant-reported emergency severity, which can result in lower-priority emergencies being overlooked.
Innovation Solution
A rescue priority determination device that uses vehicle driving condition and location information, including inertia force detection, to objectively assess the need for rescue by identifying standstill conditions and changes in location or inertia force, thereby determining high-priority rescue requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If emergency calls are handled by operator judgment in received order, then multiple calls can be processed, but rescue priority determination becomes subjective and may overlook high-priority emergencies
Solution Approach 1:
The patent replaces the mechanical system of human operator judgment with an automated determination device that uses sensors to objectively measure emergency severity. The device substitutes human subjective assessment with automated detection of objective parameters such as collision force, vehicle speed changes, and impact acceleration, thereby eliminating subjectivity while maintaining high processing capacity for multiple emergency calls
Solution Approach 2:
The determination device enables the emergency call system to self-assess priority without requiring operator intervention for evaluation. The system automatically determines rescue priority by having the vehicle's sensors self-measure emergency parameters and the determination device self-process this data to generate priority levels, freeing operators to handle multiple calls simultaneously while maintaining accurate priority determination
2Measurement precision
If objective vehicle condition data is used to determine rescue priority, then accuracy of priority determination is improved, but device complexity increases
Solution Approach 1:
The determination device is designed to perform multiple functions using a single integrated system. It simultaneously processes data from various sensors (collision force, vehicle speed, acceleration), evaluates multiple emergency scenarios (collisions, rollovers, sudden stops), and generates priority determinations for different rescue services. This multi-functionality reduces the need for separate specialized devices for each type of emergency assessment
Solution Approach 2:
The patent transforms complex physical emergency conditions into standardized measurable parameters that can be processed by the determination device. Collision forces, vehicle speeds, and accelerations are converted into quantifiable data points with defined thresholds. By changing the representation of emergency conditions from complex physical states to standardized parameters, the device can accurately assess priority without requiring complex processing mechanisms

AI summary
The rescue priority determination device comprises a driving condition information obtainer, a location information obtainer, and a rescue priority determinator. The driving condition information obtainer and the location information obtainer respectively are configured to obtain driving condition information and location information of a vehicle that made an emergency call, and the rescue priority determinator comprises one or more processors that is configured to determine the rescue priority level for the vehicle that made the emergency call based on the driving condition information and the location information. The rescue priority determinator determines that the need for rescue for the vehicle that made the emergency call is high and raises the rescue priority level based on determining that the vehicle that made the emergency call is at a standstill and that the location information of the vehicle that made the emergency call has changed.
