Abstract
An actuator for a side door of a motor vehicle is described, which brings about automatic opening or closing of the side door depending on a signal and has a device for holding the side door in any open position. The holding device is realized by a function of the electric motor itself, according to which function the control device initiates a short-circuit function of the motor phases when the motor is activated, which causes a high current flow and thus a high torque for holding the side door open. By short-circuiting the motor phases, no additional components are required, since this is a special activation function of the motor.
Claims5
An actuator for a side door of a motor vehicle, which brings about automatic opening or closing of the side door depending on a signal, comprising:
- a transmission;
- an electric motor which is activated by the signal via a control device and which, depending on said signal, generates a first torque which acts on a hinge of the side door via the transmission;
- and
- a holding device for holding the side door in an open position, the holding device further comprising:
- a short-circuit function of the electric motor;
- wherein according to the function, the control device initiates the short-circuit function of the electric motor phases when the electric motor is activated, which causes a high current flow and thus a second torque, holding the side door open, the second torque being higher than the first torque.
