committed to the auto parts diversified development.
AVAS (Acoustic Vehicle Alerting System) is an intelligent acoustic warning device independently developed by Qufu TEMB ELECTRIC specifically designed for electric and hybrid vehicles.
By simulating engine sounds, motor sounds, or customizable alert tones, the system actively emits warnings during low-speed operation, effectively alerting pedestrians and surrounding road users to approaching vehicles, significantly enhancing road safety.

✅ Intelligent Acoustic Alert
Supports multiple sound modes including engine sound, motor sound, and musical tones, with clear and recognizable audio effects
Automatically activates based on vehicle speed and gear position (typically operates at 0-30 km/h), remains silent at high speeds to balance safety and quietness
✅ Full-Scenario Adaptability
Customizable sound type, volume adjustable, and frequency to meet automaker requirements, compliant with global regulations.
Precision-controlled by a microcontroller for fast response and compatibility with various vehicle electrical architectures
✅ User-Centric Design
Low power consumption with minimal impact on vehicle range
Smooth and non-intrusive alert tones to prevent noise pollution and enhance driving comfort
