Vehicle Emergency Alert Speech Speed Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle alert systems lack the ability to dynamically control the speech speed of emergency alerts based on the vehicle's current position and surrounding environment, which can affect the effectiveness of alert dissemination in various geographical areas.
Innovation Solution
A vehicle system that includes a receiving part to receive emergency signals, an alert control part to determine the speech speed of emergency alerts based on current position information and map information, and an output part to output the alerts using the determined speech speed, allowing for adaptive voice speed adjustments for wide or narrow area notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the alert is notified at a slow voice speed to cover a wide area, then the coverage area is improved, but the alert urgency deteriorates
Solution Approach 1:
The patent applies dynamics by making the voice speed adjustable and changeable based on notification conditions. The system dynamically switches between slow voice speed (for wide area coverage) and fast voice speed (for narrow area urgency) according to the determined notification area, resolving the contradiction between coverage area and alert urgency.
Solution Approach 2:
The patent changes the voice speed parameter based on the notification area determined from map information and current position. By adjusting this critical parameter according to different geographical conditions, the system achieves both wide area coverage when needed and high urgency when needed, resolving the technical contradiction.
2Speed
If the alert is notified at a high voice speed to increase urgency, then the alert urgency is improved, but the coverage area deteriorates
Solution Approach 1:
The system dynamically adjusts voice speed based on the determined notification area. When a narrow area is identified, the system switches to fast voice speed to increase urgency, while when a wide area is identified, it uses slow voice speed for broader coverage, thus resolving the contradiction between speed and coverage area.
Solution Approach 2:
The voice speed parameter is changed according to the notification area determined from map information. This parameter adjustment allows the system to achieve high urgency in narrow areas and wide coverage in appropriate scenarios, resolving the technical contradiction between these two requirements.
3Device complexity
If a fixed voice speed is used for all situations, then the system complexity is reduced, but the adaptability to different geographical areas deteriorates
Solution Approach 1:
The patent changes the voice speed parameter based on geographical conditions and notification area determined from map information and current position data. This parameter adaptation enables the system to respond appropriately to different situations, resolving the contradiction between maintaining simplicity and achieving adaptability.
Solution Approach 2:
The system uses feedback from map information and current position data to determine the notification area and adjust voice speed accordingly. This feedback mechanism allows the system to adapt to different geographical areas without requiring overly complex manual configuration, resolving the contradiction between simplicity and adaptability.
