Abstract

A process is provided for the electronic monitoring of the on-board power supply system, or parts of the on-board power supply system, of a motor vehicle with respect to voltage peaks or voltage drops. The value of the electric voltage is continuously recorded, and a comparator circuit continuously compares a first earlier voltage value with a subsequently determined second voltage value. The comparator circuit keeps available for a predetermined time period the highest voltage value recorded up to that point-in-time.
