A door opening and closing device includes: a door drive unit capable of opening and closing a door; a detection means for detecting a subject present in an approach area; a measurement unit that measures a distance from the detection means to the subject; a determination unit that determines whether the subject has stopped in the approach area; a setting unit that sets a trigger zone in the approach area a; and a control means for starting control to drive the door drive unit when the subject is determined to have moved into the trigger zone. The setting unit sets the trigger zone to drive the door drive unit on the basis of the separation distance from the detection means to a stopped position.

Provided are a motion determination device and a motion determination method capable of correctly determining a kicking motion performed by a user about to open or close a rear gate or the like of a vehicle. The motion determination device includes two or more sensors respectively mounted on positions which are spaced apart from each other and have a relative vertical relationship in a vehicle, and detecting approach of an object, and a determination device. The determination device determines that the predetermined kicking motion has been performed, when each of the detection values shows a pattern in which the detection value becomes equal to or more than a first threshold value and then equal to or more than a second threshold value greater than the first threshold value, and thereafter becomes less than the second threshold value and then less than the first threshold value, a time until each of the detection values becomes less than the first threshold value after it becomes equal to or more than the first threshold value is within a predetermined time, and a ratio of a maximum value of the detection value by a first sensor among the two or more sensors and a maximum value of the detection value by a second sensor different from the first sensor among the two or more sensors is within a predetermined range.

The invention relates to a capacitive sensor arrangement for a motor vehicle, comprising an elongate, flat measuring electrode and at least one fastening element for fastening the measuring electrode on a support component. It is provided that the fastening element has a retaining tongue, which can be elastically deflected out of a rest position, and the uninstalled measuring electrode can be slid, for the fastening thereof, underneath the retaining tongue via a flat side in an installation motion, which elastically deflects the retaining tongue.

A lower structure of a vehicle includes a rear bumper cover, a rear floor cover serving as an under cover that is provided at a lower side, in an up-and-down direction of the vehicle, than a floor panel of the vehicle and at a front side of the vehicle relative to the rear bumper cover, and a kick sensor having a signal line which extends in a width direction of the vehicle and a sensor part placed on the signal line. The kick sensor is placed inside a closed cross-section space surrounded by a connected structure of the rear bumper cover and the under cover and formed on the side of the floor panel, isolated from an outside of the vehicle.

A device for actuating a door of a vehicle in a contact-free manner includes a capacitive proximity sensor. The proximity sensor has at least one sensor electrode for emitting an electric detection field in a detection area in front of the sensor electrode. An insulated electric conductor is arranged in front of the sensor electrode for shaping the detection field.

A radar detection system for activation of a powered closure member of a vehicle and corresponding method are provided. The system includes a radar sensor assembly having a radar transmit antenna for transmitting radar waves and a radar receive antenna for receiving the radar waves after reflection from an object in a detection zone. The radar sensor assembly outputs a sensor signal corresponding to the motion of the object in the detection zone. An electronic control unit is coupled to the radar sensor assembly and includes a data acquisition module to receive the sensor signal and a plurality of analysis modules to analyze the sensor signal to detect extracted features and determine whether extracted features are within predetermined thresholds representing a valid activation gesture. The electronic control unit initiates movement of the closure member in response to the extracted features being within the predetermined thresholds representing the valid activation gesture.

A vehicle including a number of adjustable parts each configured to be adjusted by a motor, a sensor configured to detect a first gesture performed by a first person in a first sensor area indicative of a number of operating events, and a controller configured to, responsive to receiving the first gesture from the sensor, provide the first person a first operating event option and a second operating event option to select either a first operating event or a second operating event, and responsive to receiving a second gesture indicative of a selection of the first operating event, command a first motor to adjust a first adjustable part of the number of adjustable parts.

A message is received that a mobile device is in proximity to a vehicle. For example, a cloud system may receive a message that the mobile device is in proximity to the car of a specific person. Based on the mobile device being in proximity to the vehicle, sensor information is received from one or more sensors on the vehicle. For example, an array of cameras on the vehicle may be used to detect a gesture. The received information from the one or more sensors on the vehicle is processed to identify one or more actions to implement on the vehicle. One or more commands are then sent to implement one or more actions on the vehicle. For example, the one or more commands may be to open a specific door on the vehicle and to turn on a specific heating system in the vehicle.
