A system for controlling wheel slip with mixing of a dissipative braking torque and a regenerative braking torque in a braking system with Brake-by-Wire (B-b-W) technology of a vehicle, the system comprising:

• an electronic control unit of the vehicle, the electronic control unit comprising a main wheel slip control module with mixing of the dissipative braking torque and the regenerative braking torque, the main wheel slip control module comprising a wheel slip control sub-module and a braking regeneration sub-module;
• a traction and regenerative braking control module operatively connected to the electronic control unit;
• and
• a sensor unit operatively connected to the electronic control unit;
• the wheel slip control sub-module of the main wheel slip control module with mixing of the dissipative braking torque and the regenerative braking torque of the electronic control unit of the braking system of the vehicle being configured to:
• receive a first plurality of input information for controlling the wheel slip;
• determine a braking torque request to be applied to a corner of the vehicle and a braking torque control component, based on the first plurality of input information received;
• provide the braking torque request to be applied to the corner of the vehicle, the braking torque control component, and an enabled wheel slip control confirmation value, to a braking regeneration sub-module of the main wheel slip control module with mixing of the dissipative braking torque and the regenerative braking torque of the electronic control unit of the braking system of the vehicle;
• the braking regeneration sub-module being configured to:
• receive a second plurality of input information for controlling the wheel slip;
• determine a regenerative braking torque command as a function of the braking torque request to be applied to the corner of the vehicle or of the braking torque control component, based on a status of an enabling input signal, and as a function of the second plurality of input information and of the enabled wheel slip control confirmation value received from the wheel slip control sub-module,
• the braking regeneration sub-module performing the step of determining the regenerative braking torque command as the function of the braking torque request if the status of the enabling input signal is disabled,
• the braking regeneration sub-module performing the step of determining the regenerative braking torque command as the function of the braking torque control component if the status of the enabling input signal is enabled;
• and
• the braking regeneration sub-module being further configured to determine a dissipative braking torque command as a function of the braking torque request and of the regenerative braking torque command determined by the braking regeneration sub-module.
