Autonomous Driving Content Restriction for Emergency Vehicle Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving systems do not effectively manage the driver's attention during autonomous cruising, particularly when an emergency vehicle approaches, which can cause anxiety and require immediate attention.
Innovation Solution
A control device and program that determine whether to continue autonomous driving and permit secondary tasks when an emergency vehicle is detected, and restrict content display to alert the driver of the emergency vehicle's approach.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If autonomous driving is performed during emergency vehicle approach, then driver attention is diverted to secondary tasks, but driver safety is compromised due to lack of awareness of emergency situation
Solution Approach 1:
The system dynamically adjusts the permission state for secondary tasks based on the detected approach of emergency vehicles. When an emergency vehicle is detected, the system transitions from allowing secondary tasks to restricting them, thereby adapting the operational mode to the emergency situation and ensuring driver awareness.
Solution Approach 2:
The system continuously monitors the surrounding environment for emergency vehicles and provides feedback by determining whether to maintain or revoke permission for secondary tasks. This feedback mechanism ensures that the driver's attention is appropriately directed based on the detected emergency condition.
2Reliability
If content display is restricted during emergency vehicle approach, then driver is alerted to emergency situation, but driver experience and entertainment are reduced
Solution Approach 1:
The display restriction is not static but dynamically applied based on the detected emergency condition. The system maintains normal content display during regular autonomous cruising and only restricts it when an emergency vehicle is detected, thereby balancing driver awareness with driver experience under different conditions.
Solution Approach 2:
The restriction is applied selectively to specific content displays that may divert attention from the emergency situation, while potentially allowing other types of information display that are relevant to the emergency response or navigation.
3Ease of operation
If permission state for secondary tasks is continuously maintained, then driver convenience is improved, but response to emergency situations is delayed
Solution Approach 1:
The system performs preliminary detection of emergency vehicles and proactively determines whether to revoke permission for secondary tasks before the emergency situation fully develops. This preliminary action ensures that the driver is prepared to respond to the emergency situation without delay.
Solution Approach 2:
The system rapidly transitions from the state of permitting secondary tasks to restricting them when an emergency vehicle is detected, minimizing the time the driver might be diverted from the emergency situation. This rapid state change ensures timely response to the emergency.

AI summary
A control device is used in a subject vehicle capable of performing autonomous driving with no obligation for a driver to monitor periphery. The control device determines whether a permission state, in which a specific act other than driving is permitted to the driver, is continued or not when approach of an emergency vehicle to the subject vehicle is detected during an autonomous cruising period in which the autonomous driving is being performed. The control device restricts display of a content provided to the driver when the permission state of the specific act is determined to be not continued.
