Claim 12:
13. The pressure control module of claim 10, wherein the pressure control module is formed by an at least 2-channel electro-pneumatic central pressure control module, embodied in a functional unit, for the electro-pneumatic service brake installation of the vehicle, having at least two pressure control channels which are able to be electrically controlled in terms of a brake pressure and of which one electrically controllable pressure control channel is the first pressure control channel, and of which a further electrically controllable pressure control channel is a second electrically controllable pressure control channel, wherein
a) for the electrically controllable pressure control channels, a controlled service brake pressure for the at least one service brake cylinder of the service brake installation is in each case generated based on the operating air emanating from the at least one compressed-air reservoir as a function of the electric brake request signal of the electric channel of the foot brake valve; and wherein
b) the second pressure control channel generates a second controlled service brake pressure in service brake cylinders on at least one second axle; and wherein
c) the pressure control module has at least the following: at least the first electric communications port for feeding at least one signal which represents a second service brake nominal pressure for the second pressure control channel and which is formed based on the electric brake request signal of the electric channel of the foot brake valve of the electro-pneumatic service brake installation; at least a second operating connector of the second pressure control channel for connecting at least one service brake cylinder of the at least one second axle; a second ventilation for the second pressure control channel; and wherein
d) in the pressure control module
d1) the electronic control apparatus is integrated, the electronic control apparatus as a central electronic brake control apparatus of the service brake installation being configured so that the electronic control apparatus, as a function of the signal which is present at the first electric communications port, for the second pressure control channel generates a second electric control signal, corresponding to a second nominal service brake pressure, for a second electro-magnetic valve installation of the second pressure control channel that is independent of the first electromagnetic valve installation; and
d2) the second electro-magnetic valve installation is integrated, the second electro-magnetic valve installation, as a function of the second electric control signal from the reservoir pressure of the at least one compressed-air reservoir, modulating a second actual service brake pressure for the second operating connector of the second pressure control channel; and
d3) at least one second pressure sensor is integrated, wherein the second pressure sensor for a comparison with the second nominal service brake pressure feeds a second pressure measurement signal which represents the measured second actual service brake pressure into the electronic control apparatus, wherein the electronic control apparatus in this instance is furthermore configured such that the electronic control apparatus for the second pressure control channel performs a reconciliation between the second actual service brake pressure and the second nominal service brake pressure and, as a function of this reconciliation, actuates the second electro-magnetic valve installation so that the second nominal service brake pressure is present at the second operating connector; wherein

e) the electronic control apparatus is furthermore configured such that the electronic control apparatus, as a function of output signals of the at least one inertial sensor feeds actuating signals into the first electro-magnetic valve installation and/or into the second electro-magnetic valve installation so as to carry out braking corresponding to a driving dynamics or driving stability control system by at least one service brake cylinder; and wherein
e) the electronic control apparatus has the circuit board which supports electric and electronic components, wherein routines at least for controlling the brake pressure within the first and the second pressure control channel and for the driving dynamics or driving stability control system are implemented in the electric and electronic components; wherein
f) the output signals of the at least one inertial sensor are able to be fed into the at least some electric and electronic components in order to carry out the driving dynamics or driving stability control.
