Avas System in Car

TRION avas system in car is designed to improve pedestrian safety by generating artificial sound when an electric vehicle (EV) is moving at low speeds. As EVs operate quietly, pedestrians and cyclists may not easily recognize an approaching vehicle, especially in crowded urban areas or residential zones. This system produces a clear and recognizable alert to ensure people nearby can detect the vehicle's presence in time. By combining smart control with durable hardware, the solution meets regulatory standards while creating a safer road environment for both drivers and pedestrians.

The heart of our avas system in car is a robust acoustic unit powered by a compact speaker module, protected within a waterproof and dustproof housing (IP67). The device integrates seamlessly with the CAN bus network of the vehicle, ensuring accurate communication of gear status and driving speed. This system's electronic control board manages signal transmission, while the speaker emits a consistent sound pattern with a maximum volume of 75 dB measured at one meter from the front of the car. This integration allows for precise functionality under various operating conditions, ranging from -30°C to 85°C, making it suitable for diverse driving environments.

Gear-based control: This system receives live gear position and speed data through the CAN network to determine when to activate sound.

Drive mode operation: At speeds from 0 to 20 km/h, the speaker produces a warning tone that varies with acceleration or deceleration.

Reverse gear warning: When reversing, the system generates a distinctive "Du Du" sound to alert pedestrians and nearby vehicles.

Neutral mode: This system remains silent when the vehicle is stationary or in neutral, ensuring no unnecessary noise pollution.
Through these intelligent functions, the avas system in car provides a balance between safety and comfort.

Enhanced pedestrian safety: Provides an audible cue that significantly reduces accident risks in low-speed driving scenarios.

Reliable performance: Operates in extreme temperatures and weather conditions, with a design tested for vibration resistance and durability.

Seamless vehicle integration: Works smoothly with the CAN network without requiring complex modifications.

Regulatory compliance: Meets international requirements for acoustic vehicle alerting systems, helping automakers align with safety regulations.

Low energy consumption: This system consumes less than 0.8A at 12V, minimizing its impact on overall vehicle efficiency.

Trion avas system in car can be applied across various types of electric vehicles, including passenger cars, delivery vans, city buses, and light commercial trucks. Its flexibility in working voltage (12V or 24V models) makes it adaptable to a wide range of vehicle platforms. Whether in dense city centers, parking lots, or residential neighborhoods, the system ensures drivers meet safety requirements while pedestrians gain an added layer of protection.

Our engineering team focuses on refining both hardware design and acoustic algorithms. Special attention is given to the tonal quality of the emitted sound to ensure it is distinctive without being disturbing. Through advanced testing facilities, including environmental chambers and acoustic labs, the avas system in car undergoes validation for durability, sound clarity, and compliance with automotive standards. Continuous R&D ensures compatibility with evolving EV technologies and future safety regulations.
