Acoustic Vehicle Alert System Avas

 

EV is completely driven by motors. HEV can also be completely driven by motors in some working conditions. However, the noise of motors in case of low vehicle speed is too low to draw attention of other people on the road, which brings new potential risks of transport security and may lead to accidents. In order to avoid this problem, Acoustic Vehicle Alert System (AVAS) is introduced to EV and HEV. The main function of AVAS is to send out an acoustic signal when vehicle speed is inferior to 20km/h to remind other people on the road the coming of vehicles.

Generating noise when vehicles are in low speed
Controller should get gear status of vehicle and vehicle speed.
-Neutral: no noise
-Drive: no noise when vehicle speed is zero
-Drive: from 0 to 20km/h, generating traditional engine noise, volume goes up or down with vehicle speed
-Reverse: The warning sound is "Du Du"

 

Pause Switch
-Press pause switch to deactivate the system and indicator LED is ON
-Press pause switch to activate the system and indicator LED is OFF
Pause switch should be a spring-return switch.

 

 

The product has one CAN in compliance with ISO 11898-2. The CAN baud rate is 500kbps by default. The CAN baud rate can also be customized as 250kbps.

 

The CAN protocol can be referred in another document which is provided to customers separately.
