<p>The invention relates to a parking brake modulator 1 for controlling a parking brake function of brakes of a vehicle, to a use of a brake modulator as a parking brake modulator 1 of said type, and to a brake system having said parking brake modulator 1. The parking brake modulator 1 has at least one compressed air inlet 2 via which compressed air is provided to the parking brake modulator 1. The parking brake modulator 1 also has at least one first electromagnetically actuable valve device 23, one second electromagnetically actuable valve device 24 and one third electromagnetically actuable valve device 25. Via the first valve device 23, a pneumatic pressure in a compressed air line 30, 34 can be output, which is provided at a first compressed air outlet 3 of the parking brake modulator 1. Via the second valve device 24, a pneumatic pressure in a second compressed air line 31, 35 can be output, which is provided at a second compressed air outlet 4 of the parking brake modulator 1. When the first valve device 23 is electrically de-energized and the second valve device 24 is electrically de-energized, the first compressed air line 30, 34 can be deaerated via the first valve device 23 and the second compressed air line 31, 35 can be deaerated via the second valve device 24. When likewise the first valve device 23 is electrically de- energized and the second valve device 24 is electrically de-energized and the third valve device 25 is simultaneously electrically energized, in contrast, the first compressed air line 30 can be aerated via the first valve device 23 and the second compressed air line 31 can be aerated via the second valve device 24.</p> |
