The present subject matter relates to monitoring traction for a motor vehicle. A vehicle speed and a circumferential speed of the at least one driven wheel are sensed using sensors of the motor vehicle. A control deviation is determined based on a difference of a setpoint wheel slip and an actual wheel slip. The control deviation is input to the PID traction controller. A slip acceleration is determined based on a difference of a wheel acceleration of the at least one driven wheel and a vehicle acceleration determined from the sensed vehicle speed and a circumferential speed of the at least one driven wheel. Using the PID traction controller, a drive torque of the at least one driven wheel is determined from a sum of a P-component, an I-component, and a D-component of the PID traction controller. The drive torque back to the at least one driven wheel.
