AVAS Spoken Notifications With Language Selection for Clear Vehicle Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle notification systems rely on non-spoken audio cues, which can confuse users and fail to provide clear information to both occupants and external individuals, particularly in quiet road transport vehicles (QRTVs), leading to safety concerns and user frustration.
Innovation Solution
Implementing a customizable language-based acoustic vehicle alerting system (AVAS) that uses externally positioned speakers to provide spoken-word notifications in multiple languages, linked to specific vehicle conditions or operations, allowing users to select their preferred language and ensuring clear communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If non-spoken audio cues are used for vehicle notifications, then the system is simple and energy-efficient, but user understanding and clarity of information are poor
Solution Approach 1:
The patent replaces non-spoken audio cues (traditional mechanical/acoustic notification method) with spoken-word notifications through an acoustic vehicle alerting system. This substitution transforms ambiguous beeps and sounds into clear, language-based messages that explicitly convey vehicle conditions, directly improving information clarity while accepting increased system complexity through language selection mechanisms and spoken word synthesis capabilities.
2Reliability
If spoken-word notifications in multiple languages are implemented, then user understanding and safety are enhanced, but system complexity and energy consumption increase
Solution Approach 1:
The system dynamically adapts its language output based on detected user presence and context. The AVAS activates spoken-word notifications in appropriate languages only when pedestrians or users are detected in proximity to the vehicle, rather than continuously operating. This dynamic behavior ensures safety communication reliability when needed while minimizing energy consumption during normal vehicle operation.
Solution Approach 2:
The system changes operational parameters by switching between different language modes and activation states. The language selection mechanism allows the system to adjust its output parameters (language type, volume, activation timing) based on detected conditions, ensuring reliable safety communication while optimizing energy usage by activating only when necessary.
3Adaptability or versatility
If language selection capability is added to AVAS, then adaptability to different users is improved, but device complexity increases
Solution Approach 1:
The AVAS system is designed with multi-functionality to serve multiple language requirements through a single integrated platform. The system can select from multiple languages (English, Spanish, French, German, etc.) and adjust its output based on detected user presence, combining language adaptation, audio synthesis, and safety alert functions into one universal notification system rather than requiring separate systems for each language.

AI summary
A notification system for a vehicle is disclosed. The system can incorporate speech-based feedback to be presented via the acoustic vehicle alerting system (AVAS) for the vehicle. In some embodiments, the AVAS can generate sounds to improve safety of pedestrians when the vehicle is in motion, while also being equipped to produce spoken words conveying information about a vehicle-related condition. In some cases, the system can choose a specific audio file to play back in response to a user's language selection.
