Electric vehicles (EVs) thrive on seamless technology coordination-and when it comes to TRION AVAS acoustic vehicle alert system, the CAN network is what turns "a safety feature" into "a smart, integrated solution" for OEMs. Let's dig into why this matters.
Picture an EV creeping through a crowded pedestrian zone at 10 km/h. The AVAS needs to emit a warning sound right now-but it can only do that if it knows the vehicle's speed in real time. That's where the CAN (Controller Area Network) comes in. Unlike older, clunky wiring systems, CAN acts as a "digital highway" inside the EV, letting components share data instantly. So when the EV's speed sensor detects motion, the CAN bus shoots that info to the AVAS unit in milliseconds.
For OEMs, this isn't just about safety-it's about efficiency. Our AVAS acoustic vehicle alert system plugs directly into a vehicle's existing CAN infrastructure. There's no need for extra sensors or messy wiring harnesses, which slashes installation time and reduces potential failure points. Plus, CAN's rugged design means the AVAS gets clean, accurate data even in the noisy electrical environment of an EV (think motors, batteries, and other systems all operating at once).
Let's get specific: when an EV shifts into reverse, the CAN network sends a "reverse gear engaged" signal to the AVAS. Instantly, the system triggers that distinct "Du Du" warning sound. Pedestrians hear it and know to look-no delays, no confusion. And in drive mode, as speed climbs from 0–20 km/h, the CAN-fed data lets AVAS adjust volume smoothly, so the warning is noticeable but never jarring.
In short, the CAN network transforms AVAS from a standalone device into a responsive part of the EV's ecosystem. For OEMs, that means safer vehicles, simpler manufacturing, and a smarter approach to pedestrian protection.
