The invention relates to a driving dynamics system for a vehicle, comprising: at least one wheel brake (RB1, RB2, RB3, RB4) for dissipatively braking a wheel of the vehicle; at least one braking unit (EMB, EHB) which is associated with the at least one wheel brake (RB1, RB2, RB3, RB4) and is designed to generate a dissipative braking torque by means of the at least one wheel brake (RB1, RB2, RB3, RB4); at least one electric traction motor (TM1, TM2, TM3, TM4) which can be actuated to generate a regenerative braking torque for at least one wheel or an axle of the vehicle; and a central control unit (M-ECUDomäne) which is designed to control the at least one braking unit (EMB, EHB) and the at least one electric traction motor (TM1, TM2, TM3, TM4) in combination with one another for a braking function such that a combined braking torque can be generated by means of the at least one braking unit (EMB, EHB) and the at least one electric traction motor (TM1, TM2, TM3, TM4). The braking function relates to a standard case in which a base braking torque and an additional braking torque, controlled in a closed loop, are controlled in an open loop and/or closed loop. Optionally, the base braking torque is generated by the at least one braking unit (EMB, EHB) and the additional braking torque, controlled in a closed loop, is generated by the at least one electric traction motor (TM1, TM2, TM3, TM4), or the base braking torque is generated by the at least one electric traction motor (TM1, TM2, TM3, TM4) and the additional braking torque, controlled in a closed loop, is generated by the at least one braking unit (EMB, EHB), or the at least one braking unit (EMB, EHB) and the at least one electric traction motor (TM1, TM2, TM3, TM4) together each generate the base braking torque and the additional braking torque controlled in a closed loop.
