Embodiment Construction

[0023] The exemplary embodiments described here relate to an actuator for a side door of a motor vehicle which, depending on a signal, brings about an automatic opening or closing of the side door. The actuator has an electric motor which is actuated via a signal via the control unit and which, depending on the signal, generates a torque which is applied via a transmission to the hinge of the side door.

[0024] figure 1 The actuator 1 is shown mounted on an A-pillar of a motor vehicle.

[0025] figure 2 The actuator 1 is shown in a strongly schematic side view. The actuator 1 has an electric motor (not specifically shown) with a drive shaft 2 extending upward in the figure, which exerts a corresponding torque. The shaft 2 actuates a pivot arm 6 which is mounted on the slide element 3 and which is fixed in the vehicle door. The corresponding mechanism is held by the arm 7, which is fixed on the A-pillar of the motor vehicle, as in Figure 4 shown in .

Abstract

The invention relates to an actuator for a side door of a motor vehicle, which causes an automatic opening or closing of the side door as a function of a signal, having a device for holding the side door in any open position. The holding device is implemented by the function of the motor itself, according to which the control device initiates a short-circuit function of the motor phase when actuating the motor, which short-circuit function causes a high current and thus a high torque for holding the opening of the side door. The short circuit of the motor phase does not require additional components because it relates to a special control function of the motor.

Description

technical field [0001] The invention relates to an actuator for a side door of a motor vehicle, which causes the automatic opening or closing of the side door according to a signal, the actuator having an electric motor actuated by the signal via a control unit and for holding the side door at any desired opening The device in the position, the motor generates a torque acting on the hinge of the side door via the transmission mechanism according to the signal. Background technique [0002] Opens or closes a motor vehicle door without an actuator by manipulating the door handle and applying pressure to the door. In the open position, next to the end position, the door assumes a specific holding (stop) position in which the door movement is stopped and a corresponding resistance has to be overcome in order to continue the movement. In order to achieve these holding positions, the door opening and closing mechanism is equipped with specific auxiliary devices, such as brakes, l...
