BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram of an apparatus for controlling the opening angle of a vehicle door according to an embodiment of the present invention;
Fig. 2 is a schematic cross-sectional view showing the opening angle control apparatus of the vehicle door shown in Fig. 1,
FIGS. 3 to 4 are conceptual views showing the operating states of the distance sensors,
5 to 6 are operational state diagrams of the opening angle control device of the vehicle door shown in Fig.

1 to 6, an apparatus for controlling the opening angle of a vehicle door according to an embodiment of the present invention includes a distance sensor 11 for detecting a distance to an object adjacent to a door in a state where the vehicle is stationary, An opening angle calculating section 12 for calculating an angle of opening of the door based on the distance from the object detected by the opening angle calculating section 12, a door stopping means 20 for operating the door by an opening angle calculated by the opening angle calculating section 12, And door releasing means (50) for releasing the stopping operation of the door stopping means when an external force larger than the set value is applied to the door in the opening direction.

The distance sensor 11 detects the distance d between the door and the object by detecting an object adjacent to the door, as shown in FIG. 3 and 4, when the distance sensor 11 is provided at the front end of the door, the distance sensor 11 can continuously detect the distance s from the object even when the door is opened . The object adjacent to the door can be moved while the door is opened. The distance sensor 11 continuously measures the distance (s) to the object while the door is opened, thereby rapidly changing the opening angle of the door due to the movement of the object It becomes possible to control.

For example, when the object moves away from the door, the door stopping means 20 changes the opening angle of the door to a larger value than the opening angle of the door set at the beginning. On the contrary, when the object approaches the door, . If the opening angle is changed rapidly in real time during the short time in which the door is opened, it is possible to facilitate the getting off of the passenger without limiting the opening angle of the door unnecessarily. In addition, it is possible to prevent damage to the door even when the object suddenly approaches. Hereinafter, a case where the distance sensor 11 is provided at the front end of the door will be described on the premise.

The opening angle calculator 12 receives the information on the distance between the door and the object from the distance sensor 11 and calculates the opening angle? Of the door. The opening angle (?) Of the door is the maximum angle at which the door does not hit the object. The opening angle calculating section 12 sends the calculated maximum opening angle? Of the door to the door stopping means 20 to mechanically control the door.

The door stopping means 20 includes a latching portion 21 provided on the hinge portion 41 of the door, a stopper 22 for limiting the moving distance of the latching portion 21, And a driving unit 30 for varying the position of the stopper 22 and restricting the opening angle? Of the door based on information on the opening angle? Of the door.

The hinge portion 41 of the door pivots about the hinge shaft 43 to turn the door. A stopper groove 42 for receiving the stopper 22 is formed on the outer peripheral surface of the hinge portion 41 of the door and a latching portion 21 is formed at the tip of the stopper groove 42.

The stopper 22 is movably provided in the stopper groove 42 of the hinge portion 41 along the door turning direction. A guide member 44 for guiding the stopper 22 is provided on the opposite side of the hinge portion 41. The guide member 44 is provided with a guide slit 45 fixedly coupled to the vehicle body and guiding the stopper 22 in a slidable manner. The stopper 22 is formed with a hinge bracket 23, which is linked with the driving unit 30. The guide slit 45 is formed to be narrower than the thickness of the stopper 22 and larger than the hinge bracket 23 so that the stopper 22 can slide along the outer circumferential surface of the guide slit 45.

The driving unit 30 includes a link member 31 linked to the hinge bracket 23, a push rod 32 slidably coupled to the link member 31, a ball screw 33, a feed nut 34, and a feed motor 34 for driving the feed nut 34.

The push rod 32 is formed in an elbow shape and one end thereof is slidably coupled to the link member 31. [ The ball screw 33 is provided at the other end of the push rod 32 and is linearly reciprocated by the feed nut 34. A feed nut 34 is rotatably coupled to the drive shaft of the drive motor 35 and the ball screw 33 is linearly moved while the feed nut 34 is rotated by driving of the drive motor 35. The push rod 32 moves together with the ball screw 33 and the stopper 22 connected to the link member 31 is moved.

On the other hand, in the case of a door that is automatically opened, it is also possible to output a control signal directly to an actuator that opens and closes the door. For example, in the case of the electric type, the opening angle? Of the door can be limited by controlling the driving time of the actuator through the increase or decrease of the current value.

The door releasing means 50 includes a load sensor 51 for detecting an external force applied by the occupant in the opening direction of the door, a drive control unit for outputting a command for releasing the stop operation to the driving unit 30 of the door stopping means 20 And an input unit 53 for outputting a canceling command of the stopping operation to the driving unit 30 of the door stopping means 20 by the operation of the occupant.

The load sensor 51 measures a force applied to the front end of the stopper 22 when the stopper 22 hits against the latching portion 21 of the door stopping means 20 and sends out the detected external force to the drive control portion 52 .

The drive control unit 52 receives an external force applied to the stopper 22 from the load sensor 51 and compares the external force with a predetermined value and outputs a release command to the drive unit 30 of the door stopping means 20. [ It is determined that the occupant has a desire to open the door when the external force detected by the load sensor 51 is equal to or larger than the set value, and the drive control unit 52 determines that the drive unit 30 of the door stop means 20 has stopped And outputs the release command. At this time, the driving unit 30 drives the driving motor 35 to rotate the ball screw 33 to extend the push rod 32 to move the stopper 22 backward. As a result, the stopping operation of the stopper 22, which stopped the movement of the latching portion 21, is released and the opening angle of the door can be increased.

The load sensor 51 can be mounted at a position capable of detecting an external force applied to the door in addition to the stopper 22. [ For example, the hinge bracket 23 may be provided on the hinge pin to which the hinge bracket 23 of the driving unit 30 is linked with the link member 31, or may be provided on one side of the push rod 32. Further, it can be provided on one side of the vehicle body within the turning radius of the door.

The input unit 53 is provided on the indoor side of the door by a button-type switch. For example, it can be mounted on an open handle or mounted adjacent to it. When the occupant presses the button-type input unit 53 when the door is to be forcibly opened, a command for retracting the stopper 22, that is, a command for releasing the stopping operation, is transmitted to the driving unit 30 of the door stopping means 20.

The operating state of the door stopping means 20 will be described in detail with reference to FIG. 2, FIG. 5 and FIG. Fig. 2 shows a state in which the stopper 22 is located a maximum distance from the engagement portion 21, and Fig. 5 shows a state in which the stopper 22 has moved toward the engagement portion 21. As shown in Fig. Fig. 6 shows a state in which the door is maximally opened in a state where the stopper 22 is stopped at the position shown in Fig.

First, the initial position of the stopper 22 is the maximum distance from the latching portion 21 in the state shown in Fig. When the distance sensor 11 fails to detect an object within the set distance, the door opening angle? Is maximally allowed. Therefore, the stopper 22 is stopped at the position shown in FIG. 2 and the driving unit 30 is operated . At this time, as shown in FIG. 6, the occupant can open the door at the maximum. The opening angle? Of the door becomes the maximum at the position of the stopper 22 in Fig.

3, when the distance sensor 11 detects an object within the set distance, the open angle calculating unit 12 calculates the open angle? Of the door and outputs an operation command to the drive unit 30 do. At this time, the driving unit 30 drives the driving motor 35 by the received opening angle? To move the stopper 22 toward the engaging portion 21 as shown in Fig. When the passenger opens the door in this state, the stopper 22 hits the stopper 22 at the position where the stopper 22 moves, and the door is no longer opened, thereby limiting the opening angle? Of the door.
