An operation detection device for a vehicle including a camera that captures an image of a periphery of an opening portion of a vehicle body includes a position determination unit configured to determine whether a first body part and a second body part of a user in the image captured by the camera are present in a user determination area set in the image, a gesture determination unit configured to determine, based on the image captured after it is determined that the first body part and the second body part are present in the user determination area, whether at least one of a first gesture using the first body part and a second gesture using the second body part is made, and an output unit configured to output the trigger signal when it is determined that at least one of the first gesture and the second gesture is made.

A system for adjusting a vehicle door relative to a vehicle body including an adjusting device, a control device for controlling the adjusting device. The control device is configured to receive an operating command and control the adjusting device based on receiving the operating command, and a sensor device for detecting an object. The control device is configured to evaluate for the purpose of collision protection monitoring whether an operating command is received in a near area relative to the vehicle door via an operating device. For collision protection monitoring, the control device is configured to use a first recognition area in a first operating mode upon receiving an operating command via an operating device in the near area, and in a second operating mode to use a second recognition area different from the first recognition area when an operating command is not received in the near area.

The disclosure relates to a method for activating a motorized closure element assembly of a vehicle, wherein the closure element assembly comprises a closure element, a control assembly, and a sensor assembly. The measured values of the sensor assembly are monitored by the control assembly to determine whether a triggering operating situation, defined by an operating-situation condition, is present, and an activation of the closure element assembly is triggered by the control assembly upon detection of the triggering operating situation. It is proposed that an operating-situation condition of the triggering operating situation is defined by the orientation of at least one body part of the operator about the vertical axis lying within a predetermined permitted orientation range, and whether the orientation of the body part lies within the permitted orientation range is detected by the sensor assembly and, depending thereon, the activation of the closure element assembly is triggered.

Provided is a refrigerator. While a user is holding an object in both hands, a door may be automatically and additionally opened using another part of a body other than hands.

An access control system for a vehicle includes a rear closure and a system that controls movement of the rear closure between closed and open positions. The control system including a controller and a wireless communication module having a wireless interface configured for short range wireless communication. The controller receives an actuation signal requesting transition of the rear closure to an open position from a mobile communication device carried by a vehicle user. The controller then determines when the user enters authentication and actuation zones proximate the vehicle via communication between the wireless communication module and a short range wireless communication device carried by the user. One the user is within the actuation zone, the controller generates a rear closure control signal configured to cause the rear closure to move from the closed position to the open position.

A method for activating a closure element arrangement of a motor vehicle, wherein the closure element arrangement has a closure element, a drive arrangement assigned to the closure element, and a control arrangement. In the context of operator control event monitoring by the control arrangement, monitoring is carried out to ascertain whether a predetermined operator control event is present. An activation of the drive arrangement is performed depending on the result of the operator control event monitoring. With assumed freedom of collision of the closure element from the motor vehicle surroundings, the occurrence of various special conditions does not permit the operator control event monitoring, or permits it only to a restricted extent. The control arrangement detects the occurrence of predetermined special conditions and the activation of the closure element arrangement is deactivated depending on the respectively detected special condition.

A detector includes a plurality of sensors and is configured to detect a user in preliminarily set detection areas. The sensors are arrayed horizontally at a rear portion of a vehicle such that the detection areas of the adjacent sensors overlap with each other. If any one of the sensors detects the user and outputs a detection signal (first detection signal), a threshold for a detection signal of one of the sensors adjacent to the sensor (second detection signal) is raised and the first and second detection signals are converted to first and second binary signals, respectively. A rear door is opened if the second binary signal has an output period that is contained in an output period of the first binary signal.

A sensor (1) which consists of a first electrode (3a), a ferroelectric layer (2) and a second electrode (3b) is described. The second electrode (3b) is connected to ground and the ferroelectric layer (2) is arranged between the first and second electrodes (3a, 3b).

An opening and closing body controller for controlling an opening and closing body that opens and closes an opening of a vehicle body includes driving means that drives the opening and closing body to open and close, user detection means that detects whether a predetermined motion is performed by a user when a distance between the user and the opening and closing body is within a predetermined range, and control means. The control means is configured to, when the user detection means detects the predetermined motion of the user, control the driving means so that the opening and closing body opens and closes at a first speed if the distance between the user and the opening and closing body is within the predetermined range, and so that the opening and closing body opens and closes at a second speed if the distance is out of the predetermined range.

A motion detection device includes an attached member on a vehicle body side, a sensor electrode configured to detect capacitance, and a sensor bracket. The sensor bracket has a sensor holding portion holding the sensor electrode and is attached to an inner surface of the attached member. The sensor holding portion includes a holding piece that extends from a side away from an inner surface of the attached member to a side approaching the inner surface and holds the sensor electrode, and the holding piece holds the sensor electrode at a position at which an axis of the sensor electrode is separated from the inner surface of the attached member by at least 15 mm or more.
