A method for braking a motor vehicle having an electric traction motor TM at a first axle; a first piston-cylinder unit (2; fig. 1a) actuated by means of a brake pedal (4, fig. 1); and an electrohydraulic brake system EHB. The method involves operating in a first mode or in a second mode. In the first mode, in the context of a maximum deceleration (e.g. re fig. 4a), braking is performed by the traction motor TM and the electrohydraulic brake system EHB, with the braking action determined as the sum atotal of a deceleration torque aTM of the traction motor TM and a deceleration torque aEHB of the electrohydraulic brake system EHB. A vehicle model is taken into consideration to distribute the maximum deceleration between the traction motor and the electrohydraulic brake system, the vehicle model replicating a weight distribution and a friction coefficient between a roadway and the vehicle tires. In the second mode (e.g. re fig. 4b, 0-50ms), braking is performed only by means of the traction motor TM, and the recuperation of the motor vehicle is simultaneously maximized.
