Abstract
A brake system, for a vehicle, includes a first electric-power-supply-unit (EPSU), and an electronic-brake-control-unit (EBCU) connected to the first EPSU. Furthermore, the brake system includes a first axle-pressure-modulator (APM) for service-brake-chambers associated with a first vehicle-axle. The first APM is connected to the EBCU. The brake system includes a second APM for spring-brake-cylinders associated with a second vehicle-axle. The second APM is connected to the EBCU. The brake system further includes a second EPSU, and an electronic-parking-brake-controller (EPBC). The EPBC is connected to the second EPSU. The EPBC is fluidically connected to the spring-brake-cylinders. The brake system includes a pressure modulator unit (PMU) fluidically connected to the first APM. The PMU is connected to the EPBC, which issues a control-signal for controlling the PMU. The PMU commands pneumatic-control-pressure for the first APM depending on the control-signal from the EPBC.
