An assembly for adjusting an adjustment element relative to a stationary portion of a vehicle, in particular of a vehicle door relative to a vehicle body comprises a drive motor for electromotively adjusting the adjustment element and an electrically actuatable locking device for locking the adjustment element with the stationary portion of the vehicle in a closed position, wherein the locking device has a locked condition in which the locking device is locked relative to the stationary portion for blocking the adjustment element in the closed position, and an unlocked condition in which the locking device is unlocked for adjusting the adjustment element relative to the stationary portion. A control device serves for controlling the drive motor and the locking device. It is provided that the control device is formed to actuate the drive motor for executing a diagnostic routine, while the locking device is in the locked condition.

A vehicle door controller is disclosed. The vehicle door controller is in communication with an actuator configured to control a door and is further in communication with a temperature sensing device. The controller is configured to receive a temperature signal from the temperature sensing device. Based on the temperature signal, the controller is configured to identify an actuator condition. In response to the actuator condition, the controller is configured to control the actuator to move the door to a resting position.

A door assembly includes a first door skin and a second door skin spaced apart from the first door skin. The assembly also includes an energy sensor generating an energy signature signal and a memory storing a door component operating signature. A controller is coupled to the accelerometer and forms a comparison of the energy signature signal to the door component operating signature and generates a door component operation status signal in response to the comparison.

A touch pad for operating an e-latch assembly of a motor vehicle entry system that includes a control circuit with a backup energy source and method of operating the entry system are provided. The touch pad includes a touch pad controller in communication with the control circuit of the e-latch assembly. The touch pad also includes at least one entry input sensor coupled to the touch pad controller for outputting a signal indicative of a touch to operate the e-latch assembly. The touch pad further includes a mechanical emergency switch assembly adjacent the at least one entry input sensor and including a plurality of pins electrically coupled to the control circuit for operating the e-latch assembly when the at least one input sensor is not operable due to one of a power loss and malfunction of the at least one input sensor.

An entrance system (1) comprises a swing door member (10) having a door leaf (12), and a sensor unit (S1; S) mounted to the door leaf (12), the sensor unit comprising a door angle sensor (S1). The entrance system (1) further comprises an automatic door operator (30) having a motor (34) capable of causing movement of the door member (10), a controller (31) for controlling operation of the motor (34), and a linkage (40) connected to the automatic door operator (30) and the door leaf (12) for transferring torque generated by the motor (34) to the door leaf (12). The automatic door operator (30) is operable in a learn mode (60) and an operational mode (70). The controller (31) is configured, in the learn mode (60), to automatically establish a linkage reduction curve (65) by determining, for a movement of said door member (10) between a shut closed position (18) of said door leaf and a swung open position (19) of said door leaf, the torque required by said motor (34) to cause movement of said door leaf (12) at different door leaf angles (α), the different door leaf angles being determined from measurement readings of said door angle sensor (S1). The controller (31) is configured, in the operational mode (70), to compensate for a non-linear torque transfer characteristic of the linkage (40) by applying the linkage reduction curve (65) when controlling said motor (34) to cause the door member (10) to swing open.

A door assembly includes a first door skin and a second door skin spaced apart from the first door skin. The assembly also includes an energy sensor generating an energy signature signal and a memory storing a door component operating signature. A controller is coupled to the accelerometer and forms a comparison of the energy signature signal to the door component operating signature and generates a door component operation status signal in response to the comparison.

A sensing edge is made in segments that can be used to determine at which point along the edge an obstruction occurred. Data collected can be used to determine a point in a process that the fault occurred by addressing each segment individually or as a whole. A programmable controller can be operatively coupled to the sensing edge, and can include logic to control the door and/or other equipment using data collected from the sensing edge.

During operation of the door system one or more sensors may be utilized in order to monitor the operation of the door assembly (e.g., door system, door, frame, etc.), review the operating parameters, troubleshoot potential issues, schedule and monitor service requests, review and take actions for potential security threats, and/or the like. Consequently, users may determine if the door system operates the door in accordance with the desired operating parameters by reviewing the movement, vibration, speed, acceleration, force, or the like based on the sensor information captured and use the information to adjust the door assembly. Notifications regarding the operation of the door systems may be sent automatically and/or in response to requests from users. The users may utilize one or more applications and interfaces thereof to remotely connect to the door systems in order to review and analyze the sensor information and take the desired actions.
