Circuit arrangement and method for measuring current in vehicle braking systems

摘要

The present invention relates to a circuit arrangement for controlling the current in loads by modulation of the pulse width, comprising at least two driver stages ( 10 ) provided for the actuation of the loads, and one or more current measuring devices ( 3 ), and at least one multiplexer ( 4 ) conducting current measurement signals by way of the load current in the driver stages to one or more current measuring devices in dependence on one or more control signals ( 30, 31 ) for the multiplexer, said control signals being produced by a checking device ( 5 ). The invention further describes a method wherein the moment of the current measurements is controlled by an organized chronological order.
