METHOD FOR CONTROLLING A LIFTGATE OF A MOTOR VEHICLE, CONTROL DEVICE FOR A LIFTGATE ASSEMBLY, LIFTGATE ASSEMBLY AND MOTOR VEHICLE

摘要

The invention relates to a method for controlling a liftgate (11) of a motor vehicle in order to automatically move the liftgate (11) from a closed position into an open position or from the open position into the closed position, wherein a first and a second drive unit (14a, 14b), which each couple the liftgate (11) to a motor vehicle component (13) relative to which the liftgate (11) is moved, are activated in order to move the liftgate (11), and a braking operation is started if a drive force (FML, FMR) required for moving the liftgate (11) exceeds a predefined limit value, in which braking operation the first and second drive units (14a, 14b) are activated in such a way that the first drive unit (14a) exerts a force (FML) directed in a first direction on the liftgate (11) in order to move the liftgate (11) and the second drive unit (14b) exerts a braking force (FMR) at least partially opposite to the first direction on the liftgate (11).
