Method for controlling an electronic slip-controllable braking system for a motor vehicle

A method for controlling an electronic slip-controllable braking system for a motor vehicle, the braking system being equipped with an actuating unit for specifying a braking intention by a driver of the motor vehicle, and includes multiple braking devices controllable independently of one another by an electronic control unit, a first braking device of the braking devices includes a wheel brake, onto which a drivable pressure generator is able to apply a pressure medium, which is under braking pressure, and which is equipped with a supply line, via which the pressure generator is contactable with a pressure medium reservoir, and a second braking device of the braking devices is configured to convert kinetic energy of the motor vehicle into electric energy and is equipped with a drivable electric machine, the braking devices jointly generating a braking power of the braking system, and respective proportions of the braking devices in a braking power of the braking system being variably settable by the electronic control unit, the method comprising:

• providing a connection, through which pressure medium is able to flow, between the wheel brake and the pressure medium reservoir when the second braking device by itself is able to generate the braking power.
