Patent ID: 11807202

Abstract:
A brake system (BS) includes first/second electric-power-supply-units (EPSU), and an electronic-brake-control-unit (EBCU) connected to the first EPSU. The BS includes a first axle-pressure-modulator (APM) for service-brake-chambers for a first vehicle-axle (VA). The first APM is connected to the EBCU. The BS includes a second APM for spring-brake-cylinders for a second VA. The second APM is connected to the EBCU. The BS includes a redundant-brake-pedal-sensor (BPS) connected to the EBCU. The BS includes first/second pressure-modulators (PM), which are connected to the second EPSU and redundant BPS. The first/second PMs are respectively fluidically connected to the first/second APMs. The redundant-BPS issues a first control-signal (CS) for the EBCU and a second CS for controlling the first/second PMs. The first PM commands pneumatic-control-pressure for the first APM depending on the second CS from the redundant-BPS. The second PM commands pneumatic-control-pressure for the second APM depending on the second CS from the redundant-BPS.
