Method for operating an adjustment device for at least one vehicle part of a vehicle that can be adjusted by means of an electrical drive, said adjustment device having a central control unit and at least one local control unit

A method for operating an adjustment device for at least one vehicle part of a vehicle that can be adjusted by means of an electrical drive, said adjustment device having a central control unit and at least one local control unit, wherein a respective local control unit acts directly on the electrical drive assigned thereto and is connected via a communication interface to the central control unit,

• wherein during an adjustment process carried out by means of the adjustment device, at least one operating variable of the vehicle part that can be adjusted is detected by means of at least one sensor,
• wherein each local control unit activates the electrical drive assigned thereto in a context of a pinch protection function for stopping or reversing an adjustment process if when a specified pinching criterion is met,
• wherein the central control unit transmits at least one triggering threshold value for the at least one operating variable to a respective local control unit via the communication interface with an adjustment request for the vehicle part that can be adjusted, and a reaction to be triggered upon reaching the triggering threshold value,
• wherein the central control unit if, when necessary, transmits at least one of a new triggering threshold value, a new reaction, and a new adjustment request to the respective local control unit during the adjustment process, and
• wherein a respective local control unit compares the determined values of the at least one operating variable to the current triggering threshold value(s) and independently triggers the reaction transmitted from the central control unit if when at least one operating variable exceeds or falls below the assigned current triggering threshold value.
