摘要：
An electronic regulator for motor vehicle regulation systems has at least one valve drive circuit that regulates the load current (iL) flowing through a substantially inductive load (L) by means of pulse-width modulation, and at least one electronic current measuring circuit with at least one analogue/digital converter that is a sigma-delta modulator and converts an analogue measurement signal of the load current (iL) into a digital measurement signal of the load current (iL). Also disclosed is a method for measuring current by means of sigma-delta modulation, as well as the use of the electronic regulator in a motor vehicle brake system.
