A vehicle opening and closing body control device includes: a control unit configured to control an opening and closing body drive device that drives an opening and closing body of a vehicle, and to cause the opening and closing body to open and close based on an operation request; a detection unit configured to detect an obstacle present around the opening and closing body based on a detection result of an obstacle sensor; and a setting unit configured to set a target stop position that is a position where the opening and closing body is near the obstacle based on a distance from the opening and closing body to the obstacle before operation of the opening and closing body is started. The control unit causes the opening and closing body to stop at the target stop position when the target stop position is set.

An adjustment assembly for use in a vehicle, including an adjustable part configured to move between an open position and a closed with respect to a vehicle body. The adjustable part may include an outer side and an inner side. At least a portion of the adjustable part may define an opening extending between the outer side and the inner side. The adjustment assembly may include an ultrasonic transmitter, disposed on either the adjustable part or the vehicle body and may be configured to emit a number of ultrasonic waves to an obstacle, and an ultrasonic receiver disposed on the inner side of the adjustable part and configured to receive the ultrasonic waves reflected from the obstacle through the opening.

A door safety system (3) for a door (2), having a safety component (10) arranged on a movable door element (4, 4a, 4b) of the door (2) and a supply component (11) arranged on a stationary door frame (5) of the door (2) for supplying energy to the safety component (10). The safety component (10) has an electric energy store (12) which is designed to autonomously supply electric energy to the safety component (10) when the door (2) is open, and the safety component (10) and the supply component (11) are designed to electrically charge the electric energy store (12) of the safety component (10) when the door (2) is closed.

Methods and apparatus to monitor and/or adjust operations of doors are disclosed. An apparatus includes processor circuitry to execute instructions to: monitor a position of a door panel associated with a door system; detect when a beam from a photo-eye sensor associated with the door system is in an unexpected non-triggered state based on the position of the door panel; and generate an alert or notification indicating a significance of the beam in the unexpected non-triggered state.

A vehicle includes a rear door, at least one sensor component proximate to the rear door, an alert system, a memory in which program instructions are stored, and a processor operably connected to the alert system, the at least one sensor component, and the memory. The processor executes the program instructions to detect an object within a detection zone of the at least one sensor component relative to the rear door. The processor further activates the alert system in response to the object being within a predefined protection zone of the detection zone when the rear door is not moving.

A system for adjusting a vehicle door relative to a vehicle body including an electromotive adjusting device, a control device configured to control the adjusting device and receive an operating command and control the adjusting device based on the receipt of the operating command for adjusting the vehicle door. A sensor device for detecting an object, the control device configured for collision protection monitoring, in order to recognize an object detected by the sensor device in a recognition area as a collision obstacle. The control device is configured to limit an adjustment of the vehicle door on recognition of a collision obstacle to an adjustment path dependent on the location of the collision obstacle, in that the control device determines a projection of the collision obstacle and defines the adjustment path in dependence on the projection.

A door sensor may include one or more emitters configured to emit an emission beam comprising IR light during an emitting phase. The door sensor may further include one or more receptors configured to receive a reception beam comprising the IR light reflected off of a surface during a listening phase and an interference beam from an adjacent door sensor. The door sensor may further include a controller operatively coupled to a memory storing computer-readable instructions that, when executed by the controller, cause the controller to: determine one or more of the frequency and phase of the interference beam; determine whether the door sensor should be primary or secondary to the adjacent door sensor; and adjust a timing of one or more of the emitting phase and the listening phase to reduce interference from the adjacent door sensor.
