Description

[0001] The utility model relates to the field of automotive engineering, namely to electronic systems of the car, it can be attributed to the front lighting system of the car interior; to the emergency notification system of an accident; to GLONASS / GPS navigation terminals installed on vehicles.

[0002] The LADA Granta FL interior light with an "SOS" button (ERA-GLONASS) is a single plastic module that combines the light with a diffuser, a three-position mode switch (on / off / doors), and an emergency communication unit under a cover with indicators. The unit is held in place by latches in the ceiling and receives 12 V power when the ignition is turned on (https: / / nvs-car.ru / product / plafon-osveshcheniva-salona-s-knopkoy-sos-lada-granta-fl-granta-kalina-2 / ).

[0003] The electrical equipment of LADA Vesta is known: lighting and the ERA-GLONASS system (https: / / lada-aym.github.io / LADA_Vesta / ekspluatatsiya 14.html), the interior lighting unit of which is taken as a prototype.

[0004] The interior lighting unit (ILU) provides general interior lighting, driver and front passenger lighting, and communication with the ERA-GLONASS system operator. The emergency services call system (ESC) is designed for automatic (in the event of an accident) and manual calls to the ERA-GLONASS system operator.

[0005] The microphone is used to communicate with the operator.

[0006] The "SOS" button - call the ERA-GLONASS system operator is located in the interior lighting unit.

[0007] During operation of the BOS, a defect in compliance with GOST 33468-2015 "GNSS. Test Methods for Loudspeaker Communication Devices" was detected. The cause is insufficient rigidity of the BOS housing mounted on its base, which leads to the generation of "parasitic" acoustic waves in the structure and, subsequently, excitation of the system's acoustic path.

[0008] Thus, developers are faced with the task of making design changes aimed at improving the sound quality of the AVEs and meeting the requirements of certification assessments of finished products.

[0009] The technical result of the claimed utility model is to improve the quality of the functional capabilities of the product.

[0010] The technical result is achieved by the fact that in the interior light of a car with the function of communication with the operator of the ERA-GLONASS system, consisting of a detachable housing, made with the possibility of installation in the standard place of the front interior light of the car, two functionally and structurally separated modules are combined: a lighting module, including a light source and a diffuser, and an emergency call interface module, acoustically isolated from it by its own housing, including an SOS button and a microphone.

[0011] The interface module is designed to be integrated into the ceiling light housing, with the SOS button embedded in its base. The interface module is integrated into the ceiling light housing so that the SOS button is located on the front of the ceiling light housing.

[0012] The advantages of using the integrated interface module are:

[0013] 1) the ability to use the same interface module in different car models;

[0014] 2) solution to the problem of loudspeaker communication (compliance with GOST 33468-2015);

[0015] 3) increasing the rigidity of the product structure due to the interface module’s own housing;

[0016] 4) Improved sound quality.
