Definitions
- the present invention relates to an actuator for a side door of a motor vehicle, which causes the side door to open or close automatically as a function of a signal, with an electric motor controlled by the signal via a control device which, as a function thereof, has a gearbox a hinge of the side door generated acting torque, and a device for holding the side door in any open position.
- Motor vehicle doors that are not provided with an actuator are opened or closed by actuating the door handle and applying pressure against the door.
- the door In the open position, in addition to an end position, the door assumes certain holding (latching) positions in which the door movement is stopped and a corresponding resistance has to be overcome for further movement.
- the door opening and closing mechanism is provided with certain additional devices, such as brakes, blocking devices and the like. The arrangement of such devices is correspondingly complex.
- doors of motor vehicles which are provided with appropriate actuators.
- Such an actuator for a side door of a motor vehicle is described at the beginning. It causes the side door to be opened and closed automatically when the signal is activated by actuating the door handle, a push button on the dashboard or by radio control, etc.
- an electric motor of an actuator is controlled by the signal via a control device, which depending on this, a a gear generates torque acting on a hinge of the side door.
- the door is opened or closed in this way, it being possible for this to be carried out in any position, for example an end position or any intermediate position.
- a suitable sensor device can, for example, specify the door position to be reached.
- Even with such doors that are provided with an actuator it is known to generate certain stops to hold the door open, including, for example, additional braking devices, etc. are provided, which can be provided in addition to the actuator or within the actuator.
- the present invention is based on the object of providing an actuator of the type described above, the hold mode of which can be activated particularly easily.
- this object is achieved in an actuator of the specified type in that the holding device is implemented by a function of the electric motor itself, according to which the control device initiates a short-circuit function of the motor phases when driving the motor, which causes a high current flow and thus a high torque to keep the side door open.
- the door hold function is implemented by short-circuiting motor phases via the control device (control electronics). This means that a short-circuit function is implemented in the associated software.
- the motor can hold the doors in the desired open position when the torque is high, and no additional energy is required for this.
- the short circuit induces a current in the motor phases, which generates the motor's torque.
- an active short circuit between the individual phases of the motor is initiated according to the invention via the control device.
- This short circuit leads to a high current flow and thus to a high torque of the motor.
- the motor moves a short distance and is then held. This holding torque is greater than the force applied to the door that causes the door to move.
- Certain holding positions of the door can therefore be reached and maintained without special additional devices such as braking devices, blocking devices and the like having to be provided in the actuator or in addition to the actuator.
- the actuator designed according to the invention therefore has no additional device that fixes a holding position of the door, but the electric motor itself fixes this holding position by exerting a correspondingly high holding torque through phase short-circuiting.
- the door can therefore not easily move further and, as in the prior art described at the beginning, assumes a latching position.
- the actuator designed according to the invention is attached to the vehicle body in the area of the door hinge and outputs the torque of its electric motor via a suitable gear to the door hinge to rotate it.
- a suitable gear to the door hinge to rotate it.
- a bolt in the door hinge is turned so that the door is opened or closed.
- the door can be opened up to a maximum angle of, for example, 70 °.
- Corresponding holding positions of the door can correspond to fixed holding positions or else holding positions determined by a corresponding sensor system.
- the electric motor is designed as a three-phase motor, in particular special as a brushless DC motor.
- the cogging torque of the electric motor plays no role or only a subordinate role, so that the electric motor preferably has a minimized detent torque, since its holding effect should not affect the corresponding short-circuit function.
- a certain holding positions of the side door can be provided predetermined sensor device, via the signal of which the holding function is initiated in a certain open position of the door.
- the sensor device detects an obstacle and thereby effects a corresponding initiation of the stop position by short-circuiting by sending a signal to the control device.
- the torque exerted by the motor after short-circuiting can be transformed into a corresponding holding torque for the door via a corresponding gearbox of the actuator.
- the transmission can preferably be designed in such a way that the corresponding torque of the electric motor is increased and results in an increased holding torque.
- FIG. 1 shows an exemplary embodiment of an actuator which is installed in a motor vehicle
- FIG. 2 is a highly schematic side view of the actuator
- FIG. 3 shows a highly schematic plan view of the actuator in the closed position of the door
- FIG. 4 shows a highly schematic plan view of the actuator in the open state of the door.
- FIG. 5 is a diagram showing the increase in torque when the motor is short-circuited.
- the exemplary embodiment described here is about an actuator for a side door of a motor vehicle which, as a function of a signal, causes the side door to open or close automatically.
- the actuator has an electric motor controlled by the signal via a control device, which, as a function of the signal, generates a torque acting on a hinge of the side door via a gear.
- Figure 1 shows the actuator 1 installed on the A-pillar of a motor vehicle.
- Figure 2 shows the actuator 1 in a highly schematic side view.
- the actuator 1 has an electric motor (not specifically shown) which has an upwardly extending drive shaft 2 in the figure, which exerts a corresponding torque.
- the shaft 2 actuates a rotary arm 6 gela gela on a sliding element 3, which is fixed in a vehicle door.
- the corresponding mechanism is held by an arm 7 which is attached to the A-pillar of a motor vehicle, as shown at 4.
- a rotation of the motor shaft 2 thus causes the rotary arm 6 to pivot and thus the vehicle door to be opened or closed.
- FIGS. 3 and 4 each show a schematic plan view of the actuator 1 with a corresponding actuating mechanism (gear) for the vehicle door, FIG. 3 showing the arm 6 with the door closed and FIG. 4 showing the arm 6 with the door open.
- the actuator 1 shown and described here also has a device for folding the vehicle side door in any open position, which is implemented by a function of the electric motor itself.
- the electric motor and the control device are designed so that the door-holding function is implemented by short-circuiting the motor phases via the control device (control electronics).
- the engine control thus has a short-circuit function.
- Such a short circuit is deliberately brought about, whereby the motor with a high torque can hold the door in the desired position.
- the short circuit induces a current in the motor phases, which generates the corresponding torque of the motor, which is used here as a holding torque, possibly amplified via a gearbox.
- FIG. 5 shows in a diagram the increase in the torque with a short-circuited motor, the corresponding short-circuit torque on the one hand and the corresponding short-circuit current on the other hand being shown. It can be seen that the short-circuiting of motor phases results in a significant increase in the motor torque, which ensures the corresponding holding function of the door.
