Apparatus for controlling opening/closing body

A vehicle door control method includes operating a vehicle door handle to disengage a door lock device of a vehicle door, beginning to count time upon the operation of the door handle, if the vehicle door has moved from a fully closed position after the door lock device has been disengaged, operating a power assist mechanism to move the vehicle door in an opening direction, if the vehicle door has not moved from the fully closed position, operating the power assist mechanism to urge the vehicle door to move in the opening direction, if the vehicle door moves while being urged by the power assist mechanism, the operation of the power assist mechanism is continued to move the vehicle door in the opening direction, if the vehicle door does not move while being urged by the power assist mechanism, the power assist mechanism is operated in a direction which urges the vehicle door to move to the fully closed position.

Vehicle door control method and system therefor

An apparatus for controlling an opening/closing body for automatically opening/closing the opening/closing body. The apparatus includes a displacement body movable and displaced between movable regions including a closing region, a releasing region and a neutral region, a neutral detecting first switch configured to output a first detection signal in response to passage of the displacement body through a first boundary portion of the neutral region, a neutral detecting second switch configured to output a second detection signal in response to passage of the displacement body through a second boundary portion of the neutral region, and a control unit for effecting braking control for reducing the moving speed of the opening/closing body if neither the first detection signal nor the second detection signal are detected within a predetermined period after starting of a neutral returning movement which is effected after a latch closing movement of the opening/closing body.

A method for controlling a power slide door having an operable window for a vehicle for preventing an entrapment between the power slide door and a vehicle body by limiting a slidable range of the power slide door by portion of a stopper, which the stopper functions in a condition where the window is opened more than or equal to a certain range, the method comprising steps of judging if the entrapment is generated within a predetermined range in which the power slide door can be stopped by portion of the stopper in a condition where the entrapment with a foreign object is generated during an opening operation of the power slide door, performing a reverse operation of the power slide door in a closing direction by a certain distance in a condition where the entrapment is generated within the predetermined range, and stopping the power slide door.

Method for controlling door and door control system for vehicle

The rotating speed of an output shaft of a door opening and closing motor actuating a sliding door is monitored, and whether a fluctuation value of the rotating speed is equal to or more than a first determination threshold value is determined (step S). A second determination threshold value having a pinching detecting sensitivity that is higher than the first determination threshold value is set. When it is determined that the shift lever of the transmission is in a P position, or a foot brake is operating, or a parking brake is operating, whether the fluctuation value of the rotating speed is equal to or more than the second determination threshold value is determined (step S). If the fluctuation value of the rotating speed is equal to or more than each of the determination threshold values, the sliding door is actuated in an opening direction (step S).

Device for controlling opening/closing body for vehicle

An opening and closing body control device includes an actuation device for actuating an opening and closing body which operates relative to a body, a speed detection device for detecting moving speed of the opening and closing body, and a control device for driving the actuation device based on detected results from the speed detection device. The control device conducts anti-pinch transaction when an object is pinched between the opening and closing body and the body. The control device includes a speed difference calculation device for calculating speed difference between latest speed and speed at predetermined time earlier, a speed difference memory device for memorizing predetermined number of the speed differences, an accumulation device for calculating accumulation value by accumulating predetermined number of speed differences, and a pinch detection device for conducting anti-pinch transaction by comparing the accumulation value and reference value for occurrence of pinch.

Opening and closing body control device

In order to provide a vehicle door controlling apparatus, which even when the vehicle starts to move while doors of the vehicle are in closed operation, performs insertion detection accurately without reducing the sensitivity of insertion detection. In the present invention, speed adjustment is performed by an applied voltage and a vehicle door is driven by a motor by voltage driving. The speed during the movement of the vehicle door is detected by Hall elements, and the door speed during the movement of the vehicle door is obtained from the detected signal. A controller having an insertion detection function controls the door speed to be the predetermined target door speed. In this case, the controller detects stoppage or driving of the vehicle, and when the state of the vehicle is in the driving state while the vehicle door is in closing operation, the voltage applied to the motor is increased compared to the stop state.

Opening and closing member control apparatus

A vehicle door controlling apparatus comprises a connection locking mechanism between a swinging door and a sliding door for locking the two doors by connecting them to each other. The swinging door is capable of opening or closing the front side of a vehicle opening and the second door is capable of opening or closing the rear side of the opening. The vehicle door controlling apparatus further comprises an operating switch which requests the opening of the sliding door, a rotary switch which detects a lock state between the doors, and a latch switch and a pole switch which detect a lock state at the rear side of the sliding door. When the controller detects a request for opening the sliding door, a release actuator releases the lock state, electric current is applied to a sliding motor, and electrical operation of the sliding door starts.

A door is moved in an opening direction at a first speed until the door reaches a decelerating area. A moving speed of the door in the opening direction is decelerated from the first speed to a second speed being lower than the first speed while the door has been moved in the decelerating area. The movement of the door is stopped when the door is moved beyond the decelerating area, the door comes in contact with an obstacle, and the moving speed of the door becomes lower than a predetermined speed corresponding to an open position of the door by a predetermined threshold value.

Door apparatus for a vehicle

A vehicle is provided with an opening and closing device for opening and closing the vehicle door. A hook mechanism holds the door in an open condition, an electric releasing actuator is operatively connected to the hook mechanism to unhook the hook mechanism for permitting the door to be moved in the closing direction, an electric driving device is adapted to move the door in the closing direction, and an operation device generates a signal for directing that the door be moved in the closing direction. In addition, a control device controls the operation of the electric releasing actuator based upon the signal from the operation device, and controls the electric driving device to initiate driving operation of the electric driving device after initiation of the operation of the electric releasing actuator.
