Abstract
A circuit arrangement for switching two backup valves in a rear axle module of an electronic brake system of a utility vehicle is provided, in which the circuit arrangement includes a switch at which pulse width modulation for controlling magnetic fields of inductors of the two backup valves is applied, and a diode for a slow discharge of the two backup valves in correlation with a predetermined operating state of the two backup valves, in which the diode is connected in parallel with two branches, each containing an inductor of the two backup valves, of the circuit arrangement, and in which the diode switches the two backup valves simultaneously in correlation with the predetermined operating state.
