Abstract: An axle valve module of a compressed air brake system includes a relay valve with a control pressure input connected to a control pressure line which can be connected via a changeover valve alternately to a brake pressure line conducting an introduced brake pressure or to a reservoir pressure line conducting a reservoir pressure. ABS inlet and outlet valves are each formed as a pressure-controlled diaphragm valve with assigned pilot valve, wherein the pilot valves are configured as cyclically controllable 3/2-way magnetic switching valves, A shut-off valve is arranged in the control pressure line of the relay valve, between the changeover valve and the control pressure input of the relay valve or the branch point of a control pressure line of the ABS valves, via which shut-off valve the control pressure present at the control pressure input of the relay valve can be included as required.

Abstract: A method for controlling a starting process of a vehicle includes activating a control sequence and setting a control sequence signal, defining a maximum engine drive torque, and detecting a drive request for a starting process. The method further includes, in response to the drive request, controlling a clutch-gearbox unit with an engagement process duration, controlling wheel slip of driven wheels by determining wheel speeds of the driven wheels and at least setting an output drive torque at the output shaft, and redefining the maximum engine drive torque depending on the wheel slip and a driving speed. The method also includes deactivating the control sequence and resetting the control sequence signal when limit values are reached.
