Method for monitoring a coupling connection between vehicle parts of a vehicle combination, and vehicle combination

A method for monitoring a coupling connection between vehicle parts of a vehicle combination, the vehicle parts of the vehicle combination being at least one tractor vehicle and at least one trailer, the method comprising:

• reading of a load change time at which a load change at least one of is initiated at the tractor vehicle and takes place at the tractor vehicle, wherein a tractor vehicle acceleration changes as a result of the load change;
• monitoring of a jerk value after the load change time, wherein the jerk value characterizes at least one of a tractor vehicle jerk of the tractor vehicle and a trailer jerk of the trailer;
• determining whether at least one of a tractor vehicle jerk occurs at the tractor vehicle and a trailer jerk occurs at the trailer on account of a preceding load change at a jerk time;
• and,
• identifying a degree of wear of the coupling connection between the vehicle parts in a manner dependent upon at least one of the jerk time, a time delay between the load change time and the jerk time, and the jerk value at the jerk time.
