Acoustic Vehicle Alerting System (AVAS) consists of a control unit, a power management system, an integrated amplifier, a transceiver, etc. Among them, the control unit is the main value link of the AVAS system, and the automotive MCU constitutes the core of the control unit. AVAS collects signals such as vehicle speed and gear position through the vehicle bus, senses the vehicle status, and processes different acoustic signal algorithms by a single-chip microcomputer chip or a DSP processor, and finally issues warning sounds corresponding to different vehicle speeds to remind pedestrians and other road users.
As a sound-generating device, AVAS needs to have a variety of tones and volumes corresponding to different scenes (such as different speeds, different sound backgrounds, etc.). Therefore, how to design sound synthesis, detect environmental dynamics, and achieve warning effects with different sound effects has become a major upgrade trend of AVAS, so as to provide better protection for the safety of other road users. Taking Mercedes-Benz as an example, the sound of its AVAS is different in the United States, the European Union, Japan and China. In addition, Mercedes-Benz stipulates in its design that a stationary vehicle needs to make a sound immediately when the gear is engaged, and the volume needs to be gradually increased during the subsequent starting process until the vehicle reaches 30 kilometers per hour before stopping the sound. This has become one of the differentiation directions of Mercedes-Benz's new energy vehicles.
