Abstract
An electronic controller for motor vehicle control systems having at least one valve actuation circuit is described herein. The electronic controller uses pulse width modulation to control the load current (i) flowing through an essentially inductive load (L), and has at least one electronic current measuring circuit which has at least one analog/digital converter which converts an analog measurement signal for the load current (i) into a digital measurement signal for the load current (i). The at least one analog/digital converter is a sigma-delta modulator. A method for measuring current using sigma-delta modulation and to the use of the electronic controller in a motor vehicle brake system is also described herein.
