METHOD FOR TESTING ON-BOARD DEVICES/SYSTEMS FOR CALLING EMERGENCY SERVICES OF VEHICLES Russian patent published in 2025 - IPC G01M17/00 G01R29/10 G01R31/00 H04B17/10 H04B17/20 

FIELD: testing.

SUBSTANCE: invention relates to a method of testing integrated onboard emergency call devices/systems. Vehicle is placed on the rotary table of the electromagnetic anechoic chamber. Transmitting antenna of the radiation simulator of the constellation of satellites is placed, which is connected to a navigation signal generator. Receiving-transmitting antenna of the GSM base station simulator connected to the radio communicator is placed. Call device/system is switched to the mode of receiving navigation signals and transmitting the minimum data set by means of a tone modem. Radio communicator is switched to the radio exchange mode with the emergency services call device/system. Also, the anechoic chamber is equipped with a transmitting antenna of the aimed noise generator, which is connected to the aimed noise generator. State of radio communication between the emergency services call device/system and the radio communicator is monitored. Loss of communication is achieved by increasing the power of the aimed noise generator. Radio communicator is used to receive MDS by means of SMS messages and to monitor the state of MDS reception and transmission by means of SMS messages.

EFFECT: development of a method for testing on-board devices/systems for calling emergency services under the effect of external electromagnetic interference.
