1. A brake system for a utility vehicle, comprising:
- service brake cylinders and spring brake cylinders operatively configured for braking the utility vehicle;
an electronic control device;
sensors for sensing a state of movement of the utility vehicle;
a foot brake valve for activating a service brake of the utility vehicle;
a manual control unit operatively configured to transmit to the electronic control device driver requests which are dependent on a method of activating the manual control unit;
a first module having electrically actuable valves for an anti-lock brake system;
a second module having electrically actuable valves for an electrically controlled parking brake; and
wherein the electronic control device is operatively configured to influence control of both the anti-lock brake system and the electrically controlled parking brake.
