External Autonomous Driving Display for Safe Manual Takeover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous driving vehicles face risks during events like accidents or congestion, and sudden manual intervention can endanger surrounding vehicles, while the need to indicate autonomous driving status is crucial for accident prevention.
Innovation Solution
An in-vehicle device that displays the autonomous driving state externally, allowing vehicles to recognize and respond to events by switching to manual driving, using a networked system to manage roads and communicate driving states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the autonomous driving enabled vehicle moves under autonomous driving to respond to events like accidents or congestion, then the vehicle can maintain autonomous operation, but it may be involved in the event and cause accidents
Solution Approach 1:
The system performs preliminary action by displaying the autonomous driving state to surrounding vehicles before any incident occurs. This advance notification allows other drivers to be aware of the autonomous vehicle's presence and potential reactions, enabling them to take preventive measures. The display device shows the autonomous driving state in advance, so when events like accidents or congestion occur, surrounding vehicles are already prepared to respond appropriately, reducing the risk of the autonomous vehicle being involved in incidents.
2Speed
If the driver suddenly cancels autonomous driving and performs heavy braking or abrupt steering to avoid events, then the driver can react quickly to dangers, but surrounding vehicles are also in danger
Solution Approach 1:
The system applies preliminary anti-action by notifying surrounding vehicles of the autonomous driving state before any sudden maneuvers occur. This advance warning allows other drivers to prepare for potential abrupt actions by the autonomous vehicle. When the driver does perform heavy braking or abrupt steering, surrounding vehicles are already alert and can take evasive action, converting the harmful effect of sudden maneuvers into a controlled situation where all parties are aware and can respond safely.
3Device complexity
If the autonomous driving enabled vehicle does not show its autonomous driving status to surrounding vehicles, then the vehicle system remains simple, but accident prevention is compromised
Solution Approach 1:
The system uses color changes as a simple yet effective visual communication method to convey the autonomous driving state. The display device changes the color or illumination state to indicate whether the vehicle is in autonomous driving mode, providing clear information to surrounding drivers without requiring complex communication systems. This approach maintains relative system simplicity while effectively preventing accidents through enhanced awareness.

AI summary
An autonomous driving display system (3999) includes: an autonomous driving control device (3300) to carry out autonomous driving; an autonomous driving display device (3900) display state of which is recognizable from outside a vehicle (3000); and an in-vehicle device (3500) to make the autonomous driving control device (3300) carry out autonomous driving of the vehicle (3000) upon receiving an autonomous driving instruction signal instructing autonomous driving, monitor start of the autonomous driving of the vehicle (3000) by the autonomous driving control device (3300), and control a display state of the autonomous driving display device (3900) to be in a display state different from a display state before the autonomous driving is started when the autonomous driving of the vehicle (3000) is started by the autonomous driving control device (3300).
