Autonomous Vehicle Guidance System for Emergency Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In autonomous vehicles, there is a challenge in guiding passengers and rescuers effectively during emergencies, as drivers may be unaware of the vehicle's systems or location of safety equipment, and rescuers may struggle to access the vehicle due to lack of information.
Innovation Solution
A guidance device and method that includes a first guidance device for passengers inside the vehicle and a second for rescuers outside, using voice, image, and lamp outputs to provide critical information on safety equipment, door operation, and passenger status, with a controller managing these outputs based on detected abnormalities and passenger consciousness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If autonomous vehicle systems are designed to operate without driver intervention, then automation level is improved, but driver awareness of vehicle systems and safety equipment location deteriorates
Solution Approach 1:
The system performs preliminary actions by detecting abnormalities and automatically providing guidance information to passengers and rescuers before they need it. When an abnormality is detected, the controller proactively activates the guidance system to indicate safety equipment locations and door positions, eliminating the need for driver awareness in autonomous operation mode.
2Productivity
If rescuers are provided with comprehensive vehicle information, then rescue efficiency is improved, but information transmission complexity increases
Solution Approach 1:
The system extracts and transmits only the most critical information needed for rescue operations. The guidance system specifically provides door position information and safety equipment locations to rescuers, separating essential rescue-critical data from other vehicle system information, thereby improving rescue efficiency without requiring complex comprehensive information transmission.
Solution Approach 2:
The controller acts as an intermediary that automatically processes abnormality detection and translates it into meaningful guidance information for rescuers. Rather than requiring direct complex communication between rescue systems and vehicle systems, the controller mediates by providing processed, relevant information about door positions and safety equipment, simplifying the information transmission process.
3Reliability
If multiple guidance devices are activated simultaneously for both passengers and rescuers, then response completeness is improved, but system complexity and energy consumption increase
Solution Approach 1:
The guidance system is segmented into distinct components: a first guidance device for passengers and a second guidance device for rescuers. The controller selectively activates appropriate guidance devices based on the specific abnormality detected and the needs of occupants, providing complete response information while managing system complexity through modular, conditional activation rather than simultaneous operation of all devices.
4Loss of time
If guidance information is provided immediately upon abnormality detection, then response time is improved, but accuracy of guidance may deteriorate without assessing passenger consciousness
Solution Approach 1:
The system incorporates feedback mechanisms to assess passenger consciousness state before providing guidance information. The controller receives feedback about passenger condition and uses this information to determine the appropriate timing and type of guidance activation, ensuring both timely response and accurate assessment of whether guidance is needed for conscious or unconscious passengers.

AI summary
A guidance apparatus for an autonomous vehicle and a method therefor are provided. The guidance apparatus includes a first guidance device that guides a passenger in the autonomous vehicle through first response information, a second guidance device that guides a rescuer outside the autonomous vehicle through second response information, and a controller that controls guidance on the first response information and guidance on the second response information, when abnormality occurs in the autonomous vehicle.
