EMERGENCY NOTIFICATION SYSTEM Russian patent published in 2019 - IPC B60R21/00 G08B25/10 H04M11/04 

FIELD: notification system.

SUBSTANCE: notification system for emergency situations comprises notification module (10), audio control module (30), driving module (40). Emergency notification notification module comprises sound muting control section (21), power supply control section (23). Muting control section is configured to transmit, to the audio control module, when receiving the vehicle emergency signal, muting request signal for prohibiting or reducing audio output of vehicle-mounted speaker and receiving, from audio control module, an audio muting acknowledgment signal indicating that the audio output of the speaker mounted in the vehicle is prohibited or reduced based on the muting request signal. Power supply control section is made with possibility to stop supply of electric power to the drivers excitation module, if the audio muting control section can not receive the muting acknowledgment signal in response to the muting request signal transmission.

EFFECT: reliable audio output sound attenuation, which complicates telephone conversation during notification of emergency situation, avoiding failure detection of system component modules.
