Avas Acoustic Vehicle Alert System

Electric vehicles (EVs) offer a remarkably quiet ride-a huge plus for cutting down on noise pollution. But this quietness can also create uncertainty for pedestrians, especially when EVs travel at low speeds. TRION AVAS acoustic vehicle alert system solves this challenge. It's built to make EVs safer for everyone around them by generating purposeful sounds that alert pedestrians, cyclists, and other road users when an EV is approaching. Whether an EV is navigating a busy city intersection or a quiet neighborhood street, the AVAS Acoustic Vehicle Alert System ensures safety doesn't get sacrificed for silence.

The backbone of TRION AVAS acoustic vehicle alert system is a purpose-built speaker unit. This isn't just any ordinary speaker-it's engineered to deliver clear, consistent warning sounds while holding up in the tough conditions inside a vehicle. The speaker operates on DC12V or DC24V power (with working voltage ranges of DC9V–16V for 12V models and 16V–32V for 24V models) and links directly to a vehicle's CAN network. This CAN network connection is vital because the AVAS Acoustic Vehicle Alert System relies on real-time data-like the EV's current speed and gear position-to know exactly when to activate and what sound to make. Plus, with an IP67 protection rating, the speaker is fully dustproof and can survive temporary water exposure, so it stays reliable through rain, snow, or dusty roads.

TRION AVAS acoustic vehicle alert system smartly adjusts its behavior based on how the EV is being used:

Neutral Gear: When the EV is in neutral, the AVAS stays quiet-no sound is needed when the vehicle isn't in motion.

Drive Mode (Zero Speed): Even if the EV is in drive mode, if it's not moving (say, at a stoplight), TRION AVAS acoustic vehicle alert system won't produce any sound.

Drive Mode (0–20km/h): This is when the system really shines. As an EV travels between 0 and 20km/h, the AVAS generates a distinct warning sound. The volume of this sound changes along with the vehicle's speed-getting louder as the EV speeds up and softer as it slows down. This gradual shift helps people nearby judge how close the EV is.

Reverse Mode: When an EV is in reverse, the AVAS emits a clear "Du Du" sound. This immediately lets anyone behind the vehicle know it's backing up, preventing accidents in parking lots or driveways.

By tapping into the CAN network, TRION AVAS acoustic vehicle alert system always has the most up-to-date info to trigger the right sounds at the perfect moment, keeping safety smooth and unobtrusive.

TRION AVAS acoustic vehicle alert system stands out for more than just safety-it's also about how reliably it works, how easily it integrates, and how well it serves users:

Targeted Safety: Unlike generic warning systems, TRION AVAS acoustic vehicle alert system is made specifically for EVs and focuses on the 0–20km/h speed range where pedestrian risks are highest. The sound it produces is noticeable enough to catch attention but not so loud that it's annoying, striking a balance between safety and comfort.

Smooth CAN Integration: Because it uses the vehicle's existing CAN network, there's no need for extra sensors or complicated wiring. The system pulls speed and gear data straight from the EV's built-in architecture, making it easier for manufacturers to install.

Tough for Automotive Use: The AVAS can handle extreme temperatures-working in ranges from -30°C to 85°C and surviving storage temperatures as low as -40°C or as high as 105°C. The IP67 rating means it's protected against dust and water, so you never have to doubt its performance in harsh environments.

Flexible Sound Options (For Custom Projects): For partners looking to add a unique flair, TRION AVAS acoustic vehicle alert system can be tweaked to match specific sound preferences (while still meeting safety rules). This lets EV makers align the system with their vehicle's brand without giving up safety.

TRION AVAS acoustic vehicle alert system is designed to work with every type of electric vehicle-from small city cars to large electric SUVs and delivery vans. Any EV that needs to meet pedestrian safety rules (which are becoming more common around the world) can benefit from this system. Whether a carmaker is producing affordable EVs for daily use or specialized electric vehicles for specific jobs, the AVAS fits right in, making sure every model meets safety goals without hurting style or performance.

The team behind TRION AVAS acoustic vehicle alert system combines skills in acoustics, car engineering, and electronics. We spent years researching how people perceive sounds in different places-busy city streets, quiet sidewalks, crowded crosswalks-to create a warning sound that grabs attention without being jarring. We also focused on how the system talks to a vehicle's CAN network, making sure data moves fast and accurately so the AVAS reacts instantly as the EV's speed changes. We tested the system for hundreds of hours in real-world settings, from bustling city centers to calm residential areas, to make sure it works reliably no matter where an EV goes.

Q1: Is an AVAS Acoustic Vehicle Alert System required for all EVs?
A1: Many areas now have laws that say EVs must have a system like AVAS to warn pedestrians at low speeds. Even if it's not required where you are, adding an AVAS boosts safety, which is a big plus for EVs that prioritize keeping people safe.

Q2: How does the AVAS connect to a vehicle's CAN network?
A2: The system comes with a connector that plugs into the vehicle's existing CAN network. Our technical guides have detailed instructions to help manufacturers integrate it without tricky modifications, so setup is smooth.

Q3:Can the AVAS's warning sound be customized?
A3: Yes-for partners working on custom projects, we offer options to adjust the warning sound (as long as it meets safety requirements). This lets you match the sound to your vehicle's design or brand while still keeping pedestrians safe.

Q4: What kind of maintenance does the AVAS need?
A4: The AVAS is made to be low-maintenance. With its IP67 protection and sturdy build, it can handle daily use without regular care. If there's a problem, our support team works directly with manufacturers to fix it quickly.

Q5: Does the AVAS work in very hot or cold weather?
A5: Yes. The system is tested to work in temperatures from -30°C to 85°C and can be stored in conditions as cold as -40°C or as hot as 105°C, so it's good for EVs used in any climate.
