Abstract (en)
[origin: WO2021069240A1] The invention relates to a method for monitoring at least one Y-capacitor (2, 3) of an onboard electrical system (1) of a vehicle, wherein - a current capacitance value of the at least one Y- capacitor (2, 3) and a current voltage (UB) of the onboard electrical system (1) are ascertained, - the energy currently stored in the at least one Y-capacitor (2, 3) is determined on the basis of the current voltage (UB) of the onboard electrical system (1) and the current capacitance value of the at least one Y-capacitor (2, 3) of the onboard electrical system (1), - the currently stored energy in the at least one Y-capacitor (2, 3) is compared with a specified threshold, and - if the specified threshold is exceeded, a corresponding control signal is generated. The invention additionally relates to an onboard electrical system (1).
