In the wave of modern automotive technology development, Advanced Driver Assistance Systems (ADAS) are gradually becoming standard equipment in vehicles. Among these, the Acoustic Vehicle Alerting System (AVAS) is gaining increasing attention as a critical safety component. Kepo, as a national high-tech enterprise integrating the R&D, manufacturing, sales, and service of human-machine interaction components, modules, and intelligent products, is undoubtedly worth an in-depth discussion regarding its AVAS technology design structure and quality design.
Technology Design
Unique Hardware and Software Structure
The vehicle speed signal and gear signal are transmitted to the AVAS system via CAN communication. The MCU retrieves the sound effect stored in FLASH according to control parameters, adjusts the pitch, and controls the volume to synthesize the target sound effect. This synthesized sound is then converted from digital to analog and played back through a speaker driven by a power amplifier, simulating engine noise to alert pedestrians.
Highly Flexible Audio Processing
Kepo AVAS excels in its audio processing capabilities. It supports custom audio tracks, adjustable dB values, and frequencies, as well as personalized sound effect development and adjustment software. These features enable AVAS to automatically adjust the alarm sound’s volume and frequency based on the vehicle’s driving status and surrounding environment, ensuring that pedestrians and other road users can clearly hear the warning sounds, thereby enhancing driving safety.
Quality Design
Rigorous Material Selection and Process Control
Kepo spares no effort in the quality design of AVAS. They strictly select high-quality raw materials and adopt advanced production processes and stringent quality control procedures to ensure product reliability and durability. For example, the housing of Kepo AVAS is usually made of high-strength, corrosion-resistant materials, capable of withstanding harsh weather and road conditions.
Comprehensive Performance Testing and Validation
During product development, Kepo conducts comprehensive performance testing and validation on AVAS. These tests include but are not limited to acoustic performance testing, electromagnetic compatibility testing, and environmental adaptability testing. Through these tests, Kepo ensures that AVAS can operate normally in various complex environments, providing users with stable and reliable alert services.
Continuous After-Sales Service and Technical Support
In addition to excellent product design and quality control, Kepo offers comprehensive after-sales service and technical support. They have established a complete customer service system and technical support team, capable of providing users with timely and professional technical support and solutions. Furthermore, Kepo pays attention to market feedback and changes in user needs, continuously optimizing product design and quality to meet user requirements and expectations.
Kepo AVAS demonstrates outstanding capabilities and innovation in both technology design structure and quality design. These products not only enhance vehicle safety but also provide users with a more convenient and intelligent driving experience.
