Abstract
In a method for monitoring the hitch of at least one trailer, which is pitchable to a tow vehicle, the tow vehicle having a steering system with which a steering angle is settable, the following steps are performed: a) detecting yaw oscillations of the tow vehicle over a certain period of time, e.g., 1 second to 3 seconds, at a constant or almost constant steering angle and above a predefinable speed of the tow vehicle without brake intervention, and b) evaluating the detected yaw oscillations for whether the amplitudes of the yaw oscillations do not fall below a predefinable amplitude threshold.

11. A method for monitoring a hitch of at least one trailer hitched to a tow vehicle having a steering for setting a steering angle, comprising:
-
detecting yaw oscillations of the tow vehicle over a predefined time period ranging from 1 to 3 seconds, at a substantially constant steering angle and above a predefined speed of the tow vehicle without brake intervention, and evaluating the detected yaw oscillations to determine whether the amplitudes of the detected yaw oscillations do not fall below a predefined amplitude threshold value. - View Dependent Claims (12, 13, 14, 15, 16, 17)
