The proposed solution in particular relates to a method for adjusting an adjusting part (1) on a vehicle (F), wherein an adjustment of the adjusting part (1) is controlled by using an electronic detection device (2) which detects a potential obstacle in an adjustment path of the adjusting part (1) on the basis of at least one first measured value and generates at least one control signal (r(t)) for controlling the adjustment of the adjusting part (1). At least over a defined time period, a curve of the control signal (r(t)) and/or of the first measured value as well as a curve of at least one second measured value (a(t), i(t), v(t)) changing significantly on collision of the adjusting part (1) with an obstacle are stored so as to be read out and correlated with each other for a subsequent plausibility check.

A safety device (200) is provided for a movable barrier system ((100). The safety device comprises a position sensor (210) mountable, in use, to or adjacent a barrier (110). A target (220) is mountable to the other of the barrier, such that movement of the barrier causes relative movement between the position sensor and the target. A controller (240) can communicate with the position sensor. The position sensor can detect movement of the target relative to the position sensor and output a signal to the controller. The controller can receive the output signal from the position sensor, determine one or more signal characteristics from the output signal, and compare the one or more determined signal characteristics with one or more predetermined signal characteristics to determine if the relative movement between the target and the position sensor is within a predefined range. A movement detection method is also provided.

A sensor unit includes a garage door sensor, a frame configured to be secured at one side of an opening for a garage door, and a cover. The garage door sensor is connected to said frame. The cover is configured to accommodate at least a portion of said garage door sensor. The cover is removably secured to said garage door sensor, such as for periodic cleaning.

The present invention relates to a sectional lifting door system. When the system is in normal operation, a door operator drives a cable drum to wind or unwind a cable for lifting or lowering slats. During a process of lowering the slats, if the slats is stopped or slowed unexpectedly (e.g. the slats hit an obstacle below), the door operator is disconnected from a shaft automatically. At this time, even if the door operator is still activated, the shaft does not rotate, the cable drum does not unwind the cable so that a certain tension force can be maintained on the cable and that the cable is prevented from loosening from the drum, thereby preventing the slats from falling off. Also, it can avoid the situation that the weight of the slats is completely applied to the obstacle because the cable drum continuously unwinds the cable.

A monitoring system is configured to prevent a door of a vehicle from contacting an object in a travel path of the door. The monitoring system includes an alarm device and a structured light assembly that has at least one optical projector and at least one image capturing module configured to detect an object in the travel path of the door. A control system is configured to generate a notification, with the alarm device, upon the detected presence of the object in the travel path of the door.

A device for controlling a door of a vehicle includes a drive unit that pivots the door between closed and open positions, wherein the closed and open positions define a pivoting range of the door. The device includes a control unit to control the drive unit. The device also includes a sensor unit that monitors the pivoting range. The sensor unit transmits a collision signal when an object is in the pivoting range while the drive unit is pivoting the door. The control unit transmits a switch-off signal to the drive unit if the control unit receives the collision signal.

A door ECU includes a non-detection field calculation unit calculating a non-detection field of an obstacle with reference to a location of a proximity sensor arranged in a vehicle, a travel path calculation unit calculating a travel path until the vehicle comes to a stopped state, a non-detection field movement path calculation unit calculating a movement path of the non-detection field associated with the travel path of the vehicle, a door opening operation path calculation unit calculating an opening operation path of the vehicle door when the vehicle is in the stopped state, and a door opening restriction calculation unit generating a control signal of a door check device in order to restrict the opening operation angle of the vehicle door if the vehicle door may operate to open beyond the movement path of the non-detection field.

The invention relates, among other things, to a door sensor device (20) for mounting on a door element (10), more particularly a swing door, which can be rotated about an axis of rotation (D), having at least one transmission device (21) for generating at least one monitoring beam (S) in the direction of the floor, said beam being oriented at an angle to the door leaf plane (E) of the door element (10), at least one receiving device (22) for receiving reflected or back-scattered radiation, and an evaluation device (23) for evaluating the radiation received by the receiving device (22) and generating an object detection signal. According to the invention, the evaluation device (23) is designed such that it checks whether a predefined exclusion condition is met, wherein the exclusion condition is dependent on at least three values, specifically an angle value specifying the rotational angle of the door element (10), a maximum value predefined for the evaluation device (23), said maximum value specifying a fixed, maximum permitted rotational angle of the door element (10), and a measuring-point-specific advance angle value, which specifies the angle between a section which is bounded by the measuring point (M1-Mn) formed by the monitoring beam (S) on the floor and the axis of rotation (D) of the door element (10), and the door leaf plane (E).

An opening and closing body control device for a vehicle includes: a control unit configured to control an opening and closing body drive device driving an opening and closing body of a vehicle to open and close the opening and closing body based on an operation request; and a detection unit configured to detect an obstacle present around the opening and closing body based on a detection result of an obstacle sensor. The control unit sets an operation speed of the opening and closing body to a first speed when the obstacle is not detected during an operation of the opening and closing body, and sets the operation speed to a second speed or less and causes the opening and closing body to stop at a position where the opening and closing body is close to the obstacle, when the obstacle is detected during the operation.

A door control device stops a door such that the door does not come into contact with an obstacle existing in a rotation range of the door. The door control device includes: a distance calculation unit configured to calculate a distance from the door to the obstacle; a speed calculation unit configured to calculate an actual speed of the door; a braking force setting unit configured to set a braking condition indicating transition of a braking force applied to the door; a speed estimation unit configured to estimate transition of an estimated speed of the door from start of braking until the door stops; and a braking force correction unit configured, during braking, to correct a braking force such that the braking force is increased, or reduced, when a time gradient of the actual speed is gentler than, or steeper than, that of the estimated speed.
