Abstract:
1. A method for reducing the influence of temperature-dependent changes in the mechanical properties of a closing part of a motor vehicle able to be moved by a direct current motor, on an anti-trap algorithm executed by a microcomputer of the motor vehicle, comprising: determining the mechanical properties of the movable closing part during production of the motor vehicle during a closing process of the movable closing part at a first ambient temperature, storing the determined mechanical properties in the form of a first reference characteristic in a memory of the motor vehicle in a non-volatile manner, comparing the stored first reference characteristic to a characteristic calculated by the microcomputer while the motor-vehicle is running, and while the motor-vehicle is running, the microcomputer adaptively determining a second reference characteristic by: storing the second reference characteristic in the memory of the motor vehicle in a non-volatile manner, wherein the second reference characteristic defines mechanical properties of the movable closing part during a closing process of the movable closing part at a different ambient temperature.
