1. A driving dynamics system for a vehicle, comprising:
a primary control unit for detecting and/or generating steering commands and braking commands, wherein the primary control unit is further designed to send setpoint values or braking commands to at least one brake module and to an electric steering actuator, wherein the electric steering actuator is arranged to actuate at least one axle;
a brake system having a first electrohydraulic pressure supply unit and a second electrohydraulic pressure supply unit, wherein the first electrohydraulic pressure supply unit is part of a first brake module and the second electrohydraulic pressure supply unit is part of a second brake module, wherein the brake modules are arranged in separate housings spatially apart from one another and connected to one another via two hydraulic lines;
four hydraulically actuable wheel brakes that are assigned to wheels;
electrically actuable brake pressure adjustment valves;
wherein the driving dynamics system is designed,
in order to implement at least one steering command, to actuate at least one of the pressure supply units in such a way that, using at least one of the brake modules on at least one of the wheel brakes, a pressure is built up for generating a yaw moment when a switching state of one or more valves of the second brake module changes.
