Electronically controllable pneumatic brake system in commercial vehicles and method for electronically controlling pneumatic brake system in commercial vehicles

摘要

The present invention relates to an electronically controllable pneumatic brake system (100) in a vehicle (200), comprising at least the following: wheel brakes (1, 2, 3, 4), wherein at least one vehicle axle ( HA, VA) wheel brakes (3, 4) having wheel storage cylinders (3a, 4a), wheel brakes (1, 2, 3, 4), and electronically controllable monostable bypass valve (16) A monostable bypass valve (16) that is electronically controllable between the manually operated parking brake valve (15) and the spring accumulator cylinder (3a, 4a). (16)-In the first switching position (Z1), in order to execute the manually set parking brake force (fPBm), according to the operation pressure (p15) generated by the parking brake valve (15) Vipa Controlling the output of the control pressure (p16)-In the second switching position, the air discharge pressure applied to the bypass air discharge port (16c) to execute the electrically set parking brake force (fPBe) The parking brake / brake pressure (pPB) whose output is controlled toward the spring accumulator cylinders (3a, 4a) is controlled according to (pE). The monostable bypass valve (16) automatically shifts to the first switching position (Z1) if there is no electrical operation control.
