Abstract:
In an opening/closing body control device, catching determination part (15) determines whether or not a catching in an opening/closing body has occurred based on a value of current that flows in a motor; a plurality of sensors (51 to 53) disposed to be shifted by predetermined electrical angles detect positions of magnetic poles of the motor (40); a counterclockwise pattern storage unit (14) stores a counterclockwise pattern which is a pattern corresponding to outputs of the plurality of sensors (51 to 53) and a predetermined shift in the electrical angles; and drive command part (16) controls the drive circuit (30) using a clockwise pattern or the counterclockwise pattern based on the outputs of the plurality of sensors (51 to 53), and in a case where the catching determination part (15) determines that a catching has occurred, controlling the drive circuit (30) in a predetermined pattern for eliminating the catching.

Abstract:
An apparatus for automatic movement of sliding windows in a motor vehicle, comprising a d.c. electric motor that moves a window (F) so that it slides along guides, including an electronic control module for controlling the d.c. electric motor, in particular a microprocessor. The electronic control module measures a current (I) of the motor and a position (X) of the window (F), and drives reversal of operation of the electric motor if it is verified that the current (I) is higher than a threshold current (Ith) and the position (X) of the window (F) falls within a given zone (APZ) of a path (P) of movement of the window (F). The anti-pinch circuit device measures a back electromotive force (E; Em) of the motor, and the electronic control module calculates the position of the window (F) as a function of the back electromotive force (E; Em) of the motor.
Abstract:
A drive device for pivoting a leaf, in particular a door leaf or window leaf, about a leaf axis, the drive device having a motor-transmission module, the motor-transmission module including an electric machine having a machine axis as well as a transmission having an output shaft that is mounted to be rotatable about an output axis. The electric machine is at least partially, in particular entirely, arranged in a mounting space between the leaf axis and the output axis.
Abstract:
Embodiments of a system for controlling a vehicle power tailgate are described. The system includes a motor operably connectible to a tailgate to open and close the tailgate, a processor, and a memory communicably coupled to the processor. The memory stores a tailgate control module including instructions that when executed by the processor cause the processor to, responsive to a value of a motor speed parameter being above a predetermined motor speed threshold and a value of a motor acceleration parameter being above a predetermined motor acceleration threshold during opening of a tailgate, control operation of the motor to apply a braking force to the tailgate.
Abstract:
A controller for controlling a motor of a closure and/or blind in a vehicle body is configured to determine a reference state signal comprising speed and/or current measurements, repeatedly estimate motor model parameters of the motor, determine an estimated state signal based on an input signal comprising measurements or estimates of a voltage, the estimated motor model parameters, the reference state signal and an error signal, the error signal representing a difference between the reference state signal and the estimated state signal, determine a disturbance observer signal from the error signal, compute a first derivative of the disturbance observer signal at a present moment, and reverse the motor upon determining that the first derivative of the disturbance observer signal exceeds a threshold.
Abstract:
A control device at an opening/closing section of a vehicle and a method for controlling the opening/closing section of the vehicle control a motor so that a pinch at the opening/closing section is determined accurately. The control device includes a pinch determination device that is mounted to the motor for opening/closing the opening/closing section of the vehicle and determines a pinch of a foreign object based on a change in the rotation number of the motor, and demagnetization pulse applying device for supplying power with reverse polarity to the motor in a pulse-like manner at the completion of the opening/closing.
