Description

Vehicle door opening and closing control device {CONTROLL APPARATUS FOR OPENING AND CLOSING OF VEHICLE DOOR}

The present invention relates to a vehicle door opening and closing control device, and more particularly, to a vehicle door opening and closing control device for automatically opening and closing a vehicle door.

In general, a vehicle includes a vehicle body having an interior space in which a user can ride, and a vehicle door having a structure that is rotatably coupled to the vehicle body and is rotatable depending on whether or not it is locked with the vehicle body. The vehicle door opens and closes the interior space by pivoting around the hinge according to the user's external force that is pushed or pulled while the vehicle door is unlocked from the vehicle body.

However, such a manual opening/closing method has difficulty in opening/closing operation when a user has difficulty using hands. Recently, a control device that receives an operation signal from a user through a button and opens and closes a vehicle door by operating a drive unit according to the received signal has been developed, but there is still a limitation in that the button operation using a hand is essential.

Accordingly, there is a demand for a vehicle door opening and closing control device that senses the state of the vehicle door through a sensor and opens and closes the vehicle door according to the detected state.
