The invention relates to a braking torque control device for a motor vehicle, wherein the motor vehicle comprises a first brake device and a second brake device. The first brake device is configured to apply a frictional braking torque to at least one wheel of the motor vehicle. The second brake device is configured to apply a regenerative braking torque to at least one wheel of the motor vehicle. The braking torque control device comprises an interface and a processing device. The interface receives information relating to a driving state of the motor vehicle. The processing device determines a setpoint value for the regenerative braking torque, wherein said processing device takes into consideration the received information relating to the driving state of the motor vehicle, a maximum axle braking torque that can be transmitted via the respective drive axles of the motor vehicle to an underlying surface taking into consideration a normal force acting on each of the drive axles owing to the pitching behaviour of the vehicle, and dynamics of a drivetrain of the respectively driven axles of the motor vehicle. The processing device is furthermore configured to actuate the second brake device via the interface such that the applied regenerative braking torque is adjusted by control to the setpoint value determined by the processing device.
