Method for monitoring traction for a motor vehicle

A PID drive slip controller for controlling a drive slip K of at least one driven wheel of a single-track motor vehicle, comprising:

• a vehicle speed sensor to measure a vehicle speed vFZG;
• a circumferential speed sensor to measure a wheel circumferential speed vAR;
• and
• a target slip controller to ascertain a longitudinal force potential Fx,max, which represents a maximum transmittable longitudinal force of a tire of the at least one driven wheel under current operating conditions, and is determined using an I component MAR,I of the PID drive slip controller, wherein
• a target wheel slip Ksoll input variable of the PID drive slip controller is determined by the target slip controller using the ascertained longitudinal force potential Fx,max, and
• wherein the PID drive slip controller determines a wheel drive torque MAR,PID, and controls a motor torque applied to the at least one driven wheel according to the wheel drive torque MAR,PID.
