In-Vehicle Rescue Guidance Display for Driver Abnormality Stops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle abnormality handling systems do not provide adequate support for occupants to handle driver abnormalities effectively, as they lack information on appropriate rescue methods during emergencies.
Innovation Solution
A vehicle abnormality handling support device that includes a presentation device and a control device to determine abnormal conditions and present information on handling methods, enabling occupants to take appropriate measures upon detecting driver abnormalities, such as displaying videos or images on a display device for rescue procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle stops automatically when driver abnormality is detected, then the safety of passengers is improved, but the time required for rescue operations increases
Solution Approach 1:
The system performs preliminary actions by automatically stopping the vehicle when driver abnormality is detected, creating a safe stationary environment before rescue operations begin. This preliminary stopping action prevents further safety risks while positioning the vehicle for subsequent rescue activities.
2Reliability
If information on handling methods is provided to occupants, then the effectiveness of rescue operations is improved, but the complexity of the system increases
Solution Approach 1:
The system introduces an intermediary information provision mechanism that bridges the gap between detecting driver abnormality and performing effective rescue operations. By providing handling method information to occupants through the presentation device, the system enables informed rescue actions without requiring complex direct intervention mechanisms.
Solution Approach 2:
The system enables occupants to perform self-service rescue operations by providing them with necessary handling method information. Instead of requiring external professional rescue services, the equipped occupants can independently execute appropriate rescue actions based on the provided guidance information.
3Reliability
If the door is locked during emergency stop, then the safety of occupants is improved, but the ability to perform rescue operations deteriorates
Solution Approach 1:
The door locking mechanism operates dynamically based on the rescue status. The door is locked during the emergency stop phase to ensure occupant safety, but automatically unlocks when rescue operations are initiated or completed, as detected by the information provision device. This dynamic state change resolves the contradiction between safety and rescue accessibility.

AI summary
An abnormality handling support device includes: a touch panel display that is able to display an image; and a driving support ECU configured to determine whether a display condition including that an abnormal condition indicating that a driver has difficulty driving a vehicle while the vehicle is traveling is satisfied is satisfied, and to cause the touch panel display to display a support image that is registered beforehand when the driving support ECU determines that the display condition is satisfied.
