METHOD FOR IMPROVING THE NOISE IMMUNITY OF VEHICLES Russian patent published in 2023 - IPC G01M17/00 H04B15/00 G01R29/00 

FIELD: noise immunity.

SUBSTANCE: method consists in establishing the fact of exposure to an external high-frequency electromagnetic field by the on-board systems of a motor vehicle, in switching the on-board electrical equipment to a noise-immune mode of operation. The onboard electrical equipment is switched to a noise-immune mode of operation on the basis of the fulfilment of any of the two conditions: E_meas≥E_lim or where E_meas is the level of the external electromagnetic field, E_max is the maximum permissible level of the field, E_meas1 is the level of the external electromagnetic field at the current time t₁, E_meas0 is the level of the external electromagnetic field at the time t₀ preceding t₁; t₂ is the expected time after t₁. The noise-immune mode of operation is implemented by dynamic control of the functionality of the onboard electrical equipment and includes the transition to a backup emergency internal mode of operation of each of the onboard devices, and the return to the nominal mode of controlling the functionality of the onboard electrical equipment of the PBX is carried out according to the condition Emeas≤Elim where Emeas<Elim is the limiting value of the external electromagnetic field corresponding to the criterion Emeas→Elim where P_p is the probability at which the influence of the external electromagnetic field on the performance of the vehicle is negligible.

EFFECT: increased electromagnetic safety.
