ELECTRONICALLY CONTROLLED PNEUMATIC BRAKING SYSTEM IN A COMMERCIAL VEHICLE, AND METHOD FOR ELECTRONICALLY CONTROLLING A PNEUMATIC BRAKING SYSTEM

摘要

An electronically controllable pneumatic brake system includes a brake circuit, wherein a control valve is associated with the brake circuit for the purpose of adjusting braking pressures at service brakes independently of each other, wherein the control valve comprises an electronic control input for receiving an electrical control signal and a pneumatic control input for receiving a control pressure. The pneumatic brake system additionally includes a first control unit for outputting the electronic control signal depending on a target vehicle deceleration for the electrical actuation of the control valve, a first brake valve configured to specify a first brake valve control pressure, and a second brake valve configured to output a second brake valve control pressure. The second brake valve is disposed such that the first brake valve control pressure and/or the second brake valve control pressure is output as the control pressure to the control valve.
