Product overview

Description

The AEKD-STEREOAVAS is an AutoDevKit acoustic vehicle alerting system (AVAS) demo.

It consists of an AEK-AUD-C1D9031 compact AVAS board, an AEK-MCU-C4MLIT1 domain zone controller, and two AEK-LCD-DT028V1 display expansion boards, plus two loudspeakers and a switching button.

The AEK-AUD-C1D9031 communicates with the AEK-MCU-C4MLIT1 via CAN protocol, exchanging commands like start/stop to simulate alerting sounds used in e-vehicles.

The sound is reproduced by the AEK-AUD-C1D9031 ECU through a pair of integrated class D audio amps connected to the loudspeakers.

Two AEK-LCD-DT028V1 boards with resistive touch allow the user to interact with the demo. The first screen shows a graphic simulation of the electric motor rpms, while the second allows starting/stopping the demo and regulating the sound volume and the engine rpms.

An important system safety feature reproposed in our demo consists in the open-load detection in play or mute state.

Toggling the “disconnect speaker” switch, the FDA903D embedded in the AEK-AUD-C1D9031 detects the open load in play or in mute and the blue LED lights up.

This open-load detection depends on the sound amplitude. If the blue LED does not light up, turn the volume up through the dedicated touch screen button.

Switching on the hardware mute button on the AEK-AUD-C1D9031 board, an orange LED (D7) turns on to indicate that the system is in the hardware mute state.
