While electro-mobility is bringing evident benefits for a greener driving, on the other hand electric cars are admittedly hard to hear when driving at low speeds, i.e. in front of schools, at a crossing or a traffic light. With the clear duty to protect people , especially those with visual impairments and anyone who rely on their hearing, the automotive industry is asked to meet international requirements as positively as possible, providing electric cars with Acoustic Vehicle Alerting System (AVAS): these vehicle warning sounds are designed to alert pedestrians to the presence of electric drive vehicles such as hybrid (HEVs), plug-in hybrid (PHEVs), and full battery electric vehicles (BEVs) travelling at low speeds, especially in that lowest speed range beyond which the tyres rolling noise takes over. 0ST offers the best-in-class solution for your Acoustic Vehicle Alerting System, thanks to its Automotive Class-D Audio Power Amplifiers, embedding diagnostic and speaker current monitor, a power management system IC including CAN and LIN interfaces, together with the ASIL-B 32-bit MCU hosting the firmware for the sound generation.
