摘要： A method for operating a brake system of a vehicle, where the vehicle has an electric machine usable for a regenerative braking of the vehicle and a drive unit usable in an overrun operation for an overrun braking of the vehicle, includes detecting an initiation of deceleration of the vehicle and detecting a driving situation suitable for regeneration. The method further includes initiating the overrun operation of the drive unit and the overrun braking of the vehicle and activating the regenerative braking so as to achieve a setpoint total regeneration torque. The regenerative braking is activated only after a limit value for a difference between an actual overrun regeneration torque by the overrun braking and a setpoint overrun regeneration torque is undershot.
