Claim 0:
1. A method for monitoring at least one Y-capacitance of an electrical on-board power supply of a vehicle, comprising the steps of:
ascertaining a current capacitance value of the at least one Y-capacitance and a current on-board power supply voltage of the electrical on-board power supply;
determining a currently stored amount of energy in the at least one Y-capacitance depending on the current on-board power supply voltage of the electrical on-board power supply and the current capacitance value of the at least one Y-capacitance of the electrical on-board power supply;
comparing the currently stored amount of energy in the at least one Y-capacitance to a predetermined threshold value; and
generating a control signal when the predetermined threshold value is exceeded in the comparing.
