Abstract

Provided is an apparatus for controlling a vehicle door, including a storage unit stores a speed profile corresponding to a plurality of directions and angles of various slopes depending on a specific vehicle model. A slope measure unit measures the direction and angle of slope of the vehicle, and an opening and closing detection unit detects when a door of the vehicle is opened or closed. A controller determines the direction and angle measured by the slope measure unit when the opening and closing detection unit detects whether the door is opened or closed, and controls a door drive unit to control an opening and closing speed of the door based on the speed profile corresponding the detected direction and angle of the slope stored in the storage unit. As a result, a door drive unit opens or closes the door under the control of the controller.

Claims

1. An apparatus for controlling a vehicle door, the apparatus comprising:

a storage unit configured to store a speed profile corresponding to a direction and angle of slope depending on a specific vehicle model;

a slope measure unit configured to measure a direction and angle of slope of a vehicle stopped on an inclination;

an opening and closing detection unit configured to detect whether a door of the vehicle is being opened or closed;

a controller configured to receive the direction and angle measured by the slope measure unit based upon whether the opening and closing detection unit detects that a door is being opened or closed, and wherein the controller is further configured to control a door drive unit to control an opening and closing speed of the door based on a corresponding speed profile stored in the storage unit; and

the door drive unit configured to open or close the door under the control of the controller.

2. The apparatus of claim 1, further comprising:

a stop determination unit configured to determine whether the vehicle is stopped.

3. The apparatus of claim 2, wherein the controller is configured to set a stop determination value of the stop determination unit to a first value for controlling the door drive unit.

4. The apparatus of claim 2, wherein the stop determination unit is configured to determine whether the vehicle is stopped based on at least one or more elements selected from a group consisting of a speed of the vehicle, a transmission mode, a braking state, and an ignition on-off state, as determination information.

5. The apparatus of claim 4, wherein the stop determination unit is configured to obtain the determination information from an electronic control unit (ECU) equipped in the vehicle.

6. The apparatus of claim 1, further comprising:

an object detection unit configured to detect a nearby object surrounding the vehicle.

7. The apparatus of claim 6, wherein the controller is configured to control the door drive unit so that the door of the vehicle does not come in contact with a detected object.

8. The apparatus of claim 1, wherein the direction of the slope is configured to contain at least one or more selected from a group consisting of a front facing slope, backward facing slope, left slope, and right slope.

9. A method for controlling a vehicle door, the method comprising:

storing a speed profile corresponding to a direction and angle of slope depending on a specific vehicle model, by a storage unit;

detecting whether a door of a vehicle is opened or closed, by an opening and closing detection unit;

measuring the direction and angle of slope of the vehicle, by a slope measure unit; and

controlling an opening and closing speed of the door based on the speed profile stored in the storage unit, by a door drive unit under the control of a controller.

10. The method of claim 9, wherein controlling the opening and closing speed of the door comprises controlling the opening and closing speed of the door when the vehicle is stopped.

11. The method of claim 10, wherein the stop state of the vehicle is determined by at least one selected from a group consisting of a speed, a transmission mode, a brake state, and an ignition on-off.

12. The method of claim 9, further comprising:

controlling the door not to come in contact with a nearby object surrounding the vehicle, by the door drive unit under the control of the controller.

14. The non-transitory computer readable medium of claim 9, wherein the program instruction that control the opening and closing speed of the door include program instructions that control the opening and closing speed of the door when the vehicle is stopped.

15. The non-transitory computer readable medium of claim 14, wherein the stop state of the vehicle is determined by at least one selected from a group consisting of a speed, a transmission mode, a brake state, and an ignition on-off.

13. A non-transitory computer readable medium containing program instructions executed by a controller, the computer readable medium comprising:

program instructions that store a speed profile corresponding to a direction and angle of slope depending on a specific vehicle model;

program instructions that interpret data indicating whether a door of a vehicle is opened or closed based upon detection from an opening and closing detection unit;

program instructions that interpret data indicating the direction and angle of slope of the vehicle measured by a slope measure unit; and

program instructions control opening and closing speed of the door based on the speed profile stored in the storage unit, by a door drive unit under the control of a controller.

16. The non-transitory computer readable medium of claim 13, further comprising:

program instruction that control the door not to come in contact with a nearby object surrounding the vehicle, by the door drive unit under the control of the controller.
