A method of determining actuator brake torque limits for a plurality of actuators, wherein each actuator is operable to apply a brake torque on a wheel of a vehicle, the method comprising determining, for each actuator, an actuator brake torque capability range based on an actuator specific torque capacity and a current operational state of the actuator; determining, for each wheel of the vehicle, a road condition brake torque capability range based on an estimated lateral wheel force acting on the wheel, an estimated friction between a tire surface of the wheel and a road surface, and a vertical wheel force acting on the wheel; and determining, for each actuator, an upper actuator brake torque limit and a lower actuator brake torque limit based on the actuator brake torque capability range and the road condition brake torque capability range.
