DOOR DRIVE DEVICE

EGUCHI TAKAFUMI / STEINER DANIEL / VOGT SEBASTIAN

A door drive device (2) for adjusting and/or locking a vehicle door (11) relative to a vehicle body (10) comprises an adjustment member (20), a drive element (23) operatively coupled to the adjustment member (20) such that the adjustment member (20) is movable with respect to the drive element (23) for moving the vehicle door (11) relative to the vehicle body (10), a sensor device (27) for measuring a measuring quantity indicative of a movement of the vehicle door (11) to provide a sensor signal, a brake device (21) operatively connected to the drive element (23) for braking a movement of the vehicle door (11) with respect to the vehicle body (10), and a control device (28) for controlling operation of the door drive device (2). The control device (28) is configured to compute, from said sensor signal obtained from the sensor device (27), an acceleration value indicative of an acceleration of the vehicle door (11), wherein the control device (28) is further configured to evaluate said acceleration value to distinguish a moving of the vehicle door (11) caused by a gravity force and a moving of the vehicle door (11) caused by a user action.

一种用于相对于车身(10)调节并且/或者锁定车门(11)的门驱动装置(2)，包括：调节构件(20)；驱动元件(23)，其在操作上联接到所述调节构件(20)，使得所述调节构件(20)能够相对于所述驱动元件(23)移动，以相对于所述车身(10)移动所述车门(11)；传感器装置(27)，其用于测量指示所述车门(11)的运动的测量量，从而提供传感器信号；制动装置(21)，其在操作上连接到所述驱动元件(23)，以制动所述车门(11)相对于所述车身(10)的运动；以及控制装置(28)，其用于控制所述门驱动装置(2)的操作。所述控制装置(28)被配置用以根据从所述传感器装置(27)获得的所述传感器信号计算指示所述车门(11)的加速度的加速度值，其中，所述控制装置(28)进一步被配置用以评估所述加速度值，以区分由重力引起的所述车门(11)的移动和由用户动作引起的所述车门(11)的移动。
