With the widespread adoption of new energy vehicles, their “silent” driving characteristics have improved ride comfort but introduced new safety concerns. Especially at low speeds or during reversing, pedestrians—including those with visual or hearing impairments—may have difficulty detecting approaching vehicles, increasing collision risks. To address this challenge, KEPO has launched the Three-in-One AVAS (Acoustic Vehicle Alerting System) solution, which integrates key functions to unify driving safety and user experience.
Core Functions:
Driving Warning Sound (AVAS): Complies with national and international regulations by emitting alert sounds at low speeds to enhance pedestrian awareness and safety.
Welcome Sound Effect: Plays a short sound when the vehicle is unlocked or started, improving user interaction.
Electric Horn Function: Replaces the traditional electric horn circuit, simplifying vehicle wiring and control systems.
System Advantages:
Integrated Design: Combines AVAS, welcome sound, and electric horn functions into one system, reducing the development and debugging effort of multiple independent acoustic systems.
High Compatibility: Supports analog signal input, driving speaker voltages up to 8.94 Vrms, suitable for city commuter vehicles, small commercial vehicles, and mid-to-large SUVs.
Modular Flexibility: Enables enabling or disabling of functional modules according to different vehicle requirements for versatile customization.
Acoustic Optimization: Provides standard sound libraries and customizable tuning services to ensure optimal acoustic performance.
Rigorous Validation: The system has passed full temperature range tests from -40°C to 85°C, meeting automotive-grade stability and reliability standards.
KEPO’s Three-in-One AVAS system not only complies with regulatory requirements but also simplifies OEM development processes through modular integration and output optimization, enhancing acoustic performance and ensuring road safety. At this critical stage of new energy vehicle development, we are committed to delivering practical, stable, and mass-producible acoustic solutions to help customers efficiently achieve their vehicle development goals.
