AVAS: For Every Electric Vehicle

Acoustic Vehicle Alert System (AVAS) is an audible warning system for vehicles with low noise levels, especially for electric vehicles.

Thor has been developing car sound systems for over 5 years. This expertise allows the team to create sound samples and implement them not only in diesel cars, but also in electric motors. And our main task is the mission of creating harmonious sounds for all types of transport, especially electric.

In the review, we will show one sound for each vehicle that does not have a familiar engine, but which must be heard: e-car, e-moped and e-scooter.

What is AVAS?

This is a man-made sound that mimics the sound of an internal combustion engine and is emitted at low speeds (up to 30 km/h or 18 mph) to inform road users that a vehicle is approaching.

AVAS must operate at least up to a speed of 20 km/h, also when reversing.

AVAS must not be disabled as it violates the security requirement.

The lower noise limit of AVAS is 56 dB(A), which is approximately the noise level of a refrigerator in operation.

The AVAS should not be louder than a comparable internal combustion engine to avoid noise pollution on the roads.
