Recuperative brake on a vehicle

A method for recuperation-based braking of a vehicle, comprising:

• generating electrical energy with a first electric machine of the vehicle during a braking process;
• operating with the electrical energy generated by the first electric machine a second electric machine in a zero slip mode in which a rotary field of a stator of the second electric machine synchronously follows a movement of a rotor of the second electric machine, so that no-load losses of the second electric machine are used to decrease the electrical energy generated by the first electric machine to thereby prevent overcharging of a traction battery of the vehicle;
• and
• performing the zero slip mode operation for a predetermined period of time or up to a predetermined threshold value of a state of charge of the traction battery of the vehicle until a driver requests a torque from the first electric machine or the second electric machine.
