Method and device for detecting potential pinches
A method for detecting potential pinches caused by at least one powered movable panel between a closed position and an open position, using a round including measuring a physical quantity, representative of a panel movement, when the panel is moved towards the closed position, determining if there is a lack of steadiness in said physical quantity relative to a previous round and, if not, starting a new round, determining if said lack of steadiness was already present during the previous round and, if not, storing at least one current parameter specific to the panel movement as a reference value, and starting a new round, and detecting a potential pinch if a second difference between the current parameter and the reference value is greater than or equal to a pinching threshold value, otherwise starting a new round.
Opening/closing member control device
An opening-closing member control device includes a motor that opens and closes an opening-closing member of a vehicle, and a control unit configured to stop the motor when determining that a foreign object has been entrapped by the opening-closing member and reverse the motor when a delay time elapses after stopping the motor. When the control unit determines that entrapment has occurred upon operation of a remote operation switch that is separated from the vehicle, the control unit reverses the motor after the delay time that is shorter than when determining that entrapment has occurred upon operation of a vehicle operation switch that is arranged in the vehicle.
Opening-closing body controller
An opening-closing body controller includes a motor body that opens and closes an open-close body, a control unit that controls and drives the motor body, and an inner temperature detector that detects an inner temperature of the motor body. The control unit performs an entrapment detection process in a section excluding a mask section that is set from a fully closed position of the open-close body to a preset position in an opening direction of the open-close body. The control unit corrects the mask section in accordance with the inner temperature of the motor body detected by the inner temperature detector.
Method for controlling a drive arrangement for a flap of a motor vehicle
The disclosure relates to a method for controlling a drive arrangement for a flap of a motor vehicle by a control arrangement, wherein the drive arrangement comprises a first electric drive and a second electric drive that are coupled in each case to the flap in terms of providing a drive, wherein in a determining routine current values that occur during the motorized adjustment of the flap are determined for the drives, wherein in an anti-trap protection routine the determined current values of the two drives are monitored to establish if at least one a predetermined trapping event criterion exists that represents a trapping event and wherein in the event that a trapping event criterion has occurred a trapping event routine is performed. It is proposed that a trapping event criterion is defined by virtue of the fact that a predetermined relationship of the current value of the first drive to the current value of the second drive exceeds or is below a trapping event threshold.
OPEN/CLOSE CONTROL DEVICE, OPEN/CLOSE CONTROL SYSTEM, OPEN/CLOSE CONTROL METHOD, AND PROGRAM
An open/close control device which detects pinching by an open/close body due to driving of a motor, includes a computing unit configured to compute an acceleration term based on a change in a rotational period of the motor, and a load applied to the motor based on the acceleration term, based on a signal indicating the rotation period of the motor, a determination unit configured to determine that the pinching by the open/close body occurred, when the load computed by the computing unit exceeds a predetermined determination value, and a determination value adjusting unit configured to increase the determination value when a local maximum value of the acceleration term exceeds a predetermined threshold value, or the acceleration term becomes less than or equal to a predetermined reference value, or the acceleration term decrease by a predetermined value or more, during a certain period after starting the motor.
Anti-Pinch Motor Control
A motor control system configured to detect a pinch condition of a structure actuated by a motor includes a pinch detection module configured to receive a current signal indicative of a motor current, determine a rate of change of current based on the current signal, and generate a pinch signal indicative of the pinch condition in response to either one of the motor current being greater than a current threshold and the rate of change of current being greater than a rate of change threshold. The motor control system further includes a position control module configured to control the motor to actuate the structure in response to an input and at least one of stop and reverse the motor in response to the pinch signal.
METHOD FOR DETECTING AN OBSTACLE IN AN ACCESS DEVICE
A method for state-based maintenance of an access device of a vehicle, in particular of a public transport vehicle, wherein the access device includes a moveable element and an electric drive for moving the moveable element and is attached to the vehicle. The drive is controlled with control signals, wherein actual state signals for describing the state are generated based on a detected state of the access device. The control signals are applied to a physical simulation model for computationally simulating the access device and determining expected target state signals and wherein based on a comparison between the actual state signals and associated target state signals, a maintenance state of the access device is determined. The simulation model is adjusted based on the comparison between the actual state signals and the associated target state signals.
Door monitoring system
A door assembly includes a first door skin and a second door skin spaced apart from the first door skin. The assembly also includes an energy sensor generating an energy signature signal and a memory storing a door component operating signature. A controller is coupled to the accelerometer and forms a comparison of the energy signature signal to the door component operating signature and generates a door component operation status signal in response to the comparison.
ANIMAL ENCLOSURE SAFE DOOR SYSTEM AND METHOD
An animal enclosure safe door system may include a door which may be moved between an open position and a closed position via an actuator. A controller unit may operate the actuator to move the door between the open and closed position. The controller unit may comprise a sensor engine which may be configured to detect the presence of an obstruction object which may prevent the door from moving into the closed position. If an obstruction object is detected, the controller unit may stop and/or reverse the movement of the door. A method of an animal enclosure safe door system may include: motivating the door from an open position into the closed position; detecting the presence of an obstruction object in the path of the door to the closed position; stopping the movement of the door for a period of time; and motivating the door into the closed position.
DRIVE DEVICE FOR INNER SWINGING DOOR
An inward-swing door driving device, including a motor, a worm wheel and worm reducer driven by the motor, a positive clutch, an unlocking cylinder and an unlocking connecting mechanism. The positive clutch includes an inner tooth, an outer tooth and an elastic element. The inner tooth is in transmission connection with the worm wheel and worm reducer, and the outer tooth is in coaxial transmission with a door shaft of an inward-swing door. The unlocking cylinder includes a cylinder push rod. One end of the unlocking connecting mechanism is in contact with the end portion of the cylinder push rod, and the other end of the unlocking connecting mechanism is connected with the inner tooth.
