METHOD FOR ADAPTIVELY PROVIDING NOISE IMMUNITY OF VEHICLES Russian patent published in 2024 - IPC G01R31/00 H02K11/02 H05K9/00 G01R29/08 

FIELD: vehicles.

SUBSTANCE: invention relates to motor vehicles and can be used for adaptive provision of onboard electrical equipment noise immunity to external high-frequency electromagnetic field (EMF) during vehicle operation, in particular, unmanned vehicle, in conditions of complex electromagnetic environment, affecting operability of electrical equipment. During operation of the vehicle, the external electromagnetic environment is continuously monitored with constant determination of the EMF level. When the vehicle gets into a complex electromagnetic environment, in which there is a high probability of the vehicle being affected by the electromagnetic field, implementing the onboard electrical equipment switching to the noise-immune operating mode, which is carried out by reducing the number of interconnections between the onboard electrical equipment devices/systems for the time of EMF exposure while maintaining the main functions that determine the possibility of continuing the operation of the vehicle. Due to aging processes of components of onboard electrical equipment, there is a gradual decrease in the threshold of resistance of the vehicle to the effects of electromagnetic fields; until the minimum permissible level of noise immunity is achieved, adaptive limitation of the number of functional relationships of devices/systems of onboard electrical equipment is performed, which reduces the number of electric channels and versions of EMF penetration into onboard electrical equipment.

EFFECT: reduced probability of vehicle malfunction and provision of its high electromagnetic stability.
