A door assist system for a vehicle is disclosed. The system comprises an actuator configured to control a position of the door about a hinge assembly. An interference sensor forms a portion of a door opening seal and is configured to detect an obstruction in a plurality of detection regions. The system further comprises a controller configured to control the actuator in response to a detection signal from the interference sensor.

An entrance system is disclosed which has a movable door member having a door leaf with a first vertical edge and a second vertical edge. A sensor unit monitors a zone at or near the door leaf for presence or activity of a person or object, and captures an image of an external object at the first vertical edge of the door leaf, and processing the captured image to identify an optical code and recognize a learning mode trigger instruction encoded therein. Triggered by the recognizing of the learning mode trigger instruction, a learning mode of the sensor unit is automatically entered into, in which a distance between the sensor unit and the external object at the first vertical edge is automatically measured and a field width parameter value of the sensor unit is set based on the measured distance.

A system and method for self-learning operation of gate paddles is disclosed. Opening and closing of the gate paddles requires timing and other settings to avoid injury and fare evasion. Self-learning allows a machine learning model to adapt to new data dynamically. The new data captured at a fare gate improves the machine learning model, which can be shared the other similar fare gates within a transit system so that learning disseminates.

Laser scanner monitors region in front of an opening. Monitoring region is delimited by a frame, in front of which an edge region is located. Propagation time sensing means determines position of an object in the monitoring region by a propagation time measurement of laser pulse, an evaluation unit being provided, by means of which first object information is produced, whether an object was sensed by the propagation time measurement. An intensity sensing means evaluating received laser pulse with respect to the intensity thereof and the sensed intensity is compared with a reference intensity stored in a memory unit. Second object information being provided in the event of deviation beyond a certain threshold value, whether an object is located in the hazard edge region on the basis of the intensity deviation. A “safety signal” generated by the evaluation unit if first or second object information is positive.

A vehicle includes a body and a door coupled to the body. The door is operable between opened and closed positions. A cinch assembly is operably coupled to the door. A door seal is positioned along at least a portion of a door opening, wherein the door seal includes a first conductor and a second conductor positioned therein. The first and second conductors are dielectrically isolated and cooperate to generate a capacitive signal. A controller is configured to monitor the capacitive signal and control the cinch assembly in response to the capacitive signal.

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 sensor assembly for a liftgate opening system for a rear liftgate of a motor vehicle is provided. The rear liftgate includes a door frame, a stationary window, a lock device, and an actuator for moving the lock device between locked and unlocked states. The sensor assembly includes a housing attached to the stationary window and a substrate disposed within the housing. The sensor assembly further includes a capacitive touch sensor engaging a target portion of the stationary window and configured to generate a touch signal, in response to a user touching the target portion of the stationary window. The sensor assembly further includes a proximity sensor generating a proximity signal, in response to the user being disposed within a predetermined distance of the proximity sensor.

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.
