A system for closing a door of a vehicle is disclosed. The system includes: at least one sensor configured to detect a velocity and a position of the door; a brake configured to decrease the velocity of the door; an actuator configured to move the door to a closed position; and a controller configured to control operation of the at least one sensor, the brake, and the actuator.

An exemplary armature assembly is configured for use with a door closer comprising a pinion, and generally includes a first arm configured for rotational coupling with the pinion, a second arm pivotably coupled to the first arm at a pivot joint, and a hold-open mechanism. The hold-open mechanism generally includes a clutch having a decoupling and a coupling state, and an electromechanical driver operable to transition the clutch between the coupling state and the decoupling state. With the clutch in the decoupling state, a first torque is operable to cause relative pivoting of the arms. With the clutch in the coupling state, the first torque is inoperable to cause relative pivoting of the arms, and a second torque greater than the first torque is operable to cause relative pivoting of the arms.

A door control system is provided. The control system includes a controller configured to control a door via a motor. The motor is powered by a battery and bypasses the controller via relays and/or switches when power to the controller is disconnected.

A vehicle roof assembly comprises an electronic control circuitry and at least one sensor operatively coupled to the electronic control circuitry. An output of the sensor exhibits hysteresis. A method of operating the vehicle roof assembly comprises performing a sensor power-down sequence. The sensor power-down sequence of steps comprises switching off the sensor; switching on the sensor; detecting the output of the sensor; storing the output of the sensor in a memory; and switching off the sensor. The method prevents inadvertent position drift due to hysteresis effects during a power toggle.

A door closer assembly includes a door closer without a powered drive for closing a door. The door closer includes an energy accumulator, wherein the energy accumulator is chargeable by manually opening the door and wherein the energy accumulator discharges for closing the door. A sensor unit is also included for detecting an angle information with regard to the opening angle of the door.

A system for determining a door condition includes a hinge including a first portion coupled with a door and a second portion coupled with a vehicle frame and rotatably coupled with the first portion. The system further includes a sensor outputting a signal related to a position of the first portion relative to the second portion and a controller receiving the signal and determining whether the signal corresponds to a door closed condition or a door open condition.

Disclosed is an access control apparatus according to the present invention. The access control apparatus includes: a body located on a passage and having a plurality of support frames; an opening and closing part detachably attached between the plurality of support frames to open and close the passage; and a driving part coupled to the body and the opening and closing part to control an operation of the opening and closing part and having an angle control module for adjusting an opening and closing angle of the opening and closing part and a speed control module for setting an opening and closing speed of the opening and closing part, wherein the driving part controls the opening and closing part so that the opening and closing part is stopped from closing at a given angle through the angle control module.

An obstacle detecting device for detecting an obstacle around a vehicle includes a sensor, a notifying unit, an operation detecting unit, and a control unit. The sensor is installed at a fixed portion of the vehicle to detect an obstacle within a predetermined detection range with an origin corresponding to a position where the sensor is installed. The notifying unit provides a notification based on a signal output from the sensor. The operation detecting unit detects an operation of a movable portion of the vehicle moving within the detection range of the sensor. The control unit is enabled to inhibit a notifying operation of the notifying unit when the operation detecting unit detects the operation of the movable portion.

A vehicle door control system is provided, and includes a body hinge member connected to the vehicle body, a door hinge member connected to the door, a brake and a control system. The brake includes a plate pack that includes a plurality of body brake plates connected to the body hinge member, and interleaved with a plurality of door brake plates connected to the door hinge member. The plate pack is positionable in a braking state in which the body brake plates and the door brake plates are frictionally engaged with one another to provide a first resistance to relative rotation therebetween so as to hold the vehicle door in a selected position, and a release state in which the body brake plates and the door brake plates provide a second resistance to relative rotation therebetween that is less than the first resistance.

A control apparatus controlling an opening and closing member for a vehicle includes a drive control unit operating an opening and closing member of the vehicle by a motor serving as a drive source, and a catch detection unit detecting a catch of a foreign object caught by the opening and closing member in response to a current value of the motor. The drive control unit includes a motor control signal output unit outputting a motor control signal for supplying a drive power to the motor, and an advance-angle value setting unit setting an advance-angle value for advancing a phase of the motor control signal. The advance-angle value setting unit includes an advance-angle value increase prohibition unit prohibiting increase setting of the advance-angle value in a case where the current value of the motor reaches an advance-angle value increase prohibition current value.
