Method and system for regulating a rear power lift of an agricultural production machine

A method for regulating a rear power lift of an agricultural production machine in an agricultural combination, wherein the agricultural combination has an agricultural production machine and an agricultural attachment, wherein the agricultural attachment is connected to the agricultural production machine via a rear power lift of the agricultural production machine, wherein the agricultural production machine has a driver assistance system which regulates one or more machine parameters of the rear power lift, wherein the driver assistance system regulates the one or more machine parameters of the rear power lift using one or both of a position regulation or a traction regulation on which a slip control is superimposed, the method comprising:

• accessing a characteristic diagram that includes dependencies between soil properties and tire properties and the slip;
• determining, by the driver assistance system using the characteristic diagram that includes dependencies between soil properties and tire properties and the slip, a target slip for slip regulation optimized for one or more of the position regulation, the traction regulation, or working depth regulation depending on at least one existing soil property and at least one existing tire property;
• and
• regulating the rear power lift to the target slip.
