A number of illustrative variations may include a system including brake-to-steer algorithms may achieve lateral control of a vehicle without longitudinal compensation but may also force a vehicle to slow down too rapidly before appropriate lateral movement can be achieved and may deliver an unnatural driving experience for vehicle occupants. A more natural feeling deceleration may be achieved by optimally selecting appropriate transmission shifts to allow for optimal engine speed or electric motor speed and torque based on current vehicle speed thereby reducing undesirably longitudinal disturbance.

An antilock control method for a braking system of a vehicle has at least the following steps: upon the presence of a brake request signal, outputting a brake control signal and building up a brake pressure by a braking medium at a wheel brake of a vehicle wheel, measuring a wheel speed of the vehicle wheel to be braked, and determining a wheel slip of the vehicle wheel, upon meeting a first traction criterion or a locking tendency of the vehicle wheel, activating a wheel drive unit and applying a wheel drive torque on the vehicle wheel to increase the wheel circumferential velocity and to reduce the wheel slip until a second traction criterion is met. The brake force introduced in the wheel brake is controlled as a function of the wheel slip by releasing the brake pressure upon satisfying a first traction criterion.
