Abstract: The purpose of the present invention is to solve fundamentally a problem by avoiding a situation in which a workable solution is not found except for a method for attaching a door cushion with excellent elasticity, resilience, mechanical strength, and transparency or making drivers pay attention in order to reduce damage caused by scratching or stamping (hereinafter referred to as dinge) the door of an adjacent car while a car is parked. By using the power held in the car as a power source, a distance sensor installed on each door of the car measures the distance to an adjacent vehicle or obstacle, and a detected signal is sent to a control box installed in the door of the car. The control box transmits a predetermined electrical control signal corresponding to the input signal to a stepping motor set installed inside the door of the car by an internal operation using the input data. Then, the operation of the stepping motor causes an arm coupled to the shaft of the motor to connect to the groove of a rod attached to the car body, so that the door of the car is opened and closed at the maximum angle on the basis of the hinge of the car body while the distance from the door to the adjacent car or obstacle is maintained to the extent that a door dinge does not occur. Therefore, as the door of the car is opened in consideration of the distance to the adjacent vehicle or obstacle, a door dinge occurring during parking even when the driver is too careful can be fundamentally prevented.
