Vehicle Automatic Accident Report System

Solution Overview

Problem

In emergency report systems, the delay in transmitting accident information from multiple vehicles to a server apparatus can hinder immediate emergency dispatch, especially in environments with insufficient communication capacity, leading to prolonged response times for rescue teams.

Innovation Solution

The vehicle automatically detects accidents, collects relevant information, and assesses the communication environment; if capacity is insufficient, it transmits estimation results of occupant injury instead of detailed information, ensuring timely emergency reporting and reducing dispatch delays.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If detailed accident information is transmitted from multiple vehicles to the server apparatus, then the accuracy of injury estimation is improved, but the transmission time increases and communication capacity requirements increase

Engineering Contradiction:

Improveinjury estimation accuracyVSAvoidtransmission delay

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system transmits only the most critical accident information (partial action) when communication capacity is limited, rather than waiting to transmit all detailed information. This allows immediate emergency response while maintaining essential estimation accuracy, resolving the contradiction between complete information transmission and timely transmission.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system dynamically changes the information transmission parameters based on communication environment assessment. When communication capacity is insufficient, it prioritizes transmitting critical parameters (location, basic accident type) over detailed parameters (exact impact force, complete sensor data), thereby adapting the transmission to available resources while maintaining essential functionality.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If the vehicle waits for appropriate communication environment before transmitting information, then transmission reliability is improved, but the response time increases

Engineering Contradiction:

Improvetransmission reliabilityVSAvoidemergency response time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The vehicle performs preliminary assessment of the communication environment immediately upon detecting an accident, before full information transmission is attempted. This preliminary action allows the system to quickly determine whether to transmit critical information immediately or wait for better conditions, balancing reliability with response time by making rapid initial decisions.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system transmits only the most critical accident information (partial action) when communication capacity is limited, rather than waiting to transmit all detailed information. This allows immediate emergency response while maintaining essential estimation accuracy, resolving the contradiction between complete information transmission and timely transmission.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A vehicle with an automatic accident report function. The vehicle includes a transmitter, a collector, a determiner, and a vehicle estimator. The transmitter automatically transmits, to a server apparatus, accident emergency information that is usable by the server apparatus to estimate injury of an occupant of the vehicle when an accident of the vehicle is detected or forecasted. The collector collects, in the vehicle, information of the vehicle involved in the accident. The determiner determines whether a communication environment is appropriate for transmission of the information from the transmitter to the server apparatus. The vehicle estimator estimates the injury of the occupant, using the information collected by the collector. If the communication environment is inappropriate, the transmitter transmits, as the emergency information to the server apparatus, estimation results of the injury of the occupant estimated by the vehicle estimator, instead of the information of the vehicle collected by the collector.
