Abstract

A steering and driving interface device mounted in a vehicle includes a rail part fixed in the vehicle and elongated in a first direction, and a driving part coupled to the rail part. The driving part is configured to move in the first direction and control an acceleration and deceleration of the vehicle. The steering and driving interface device also includes: a steering part disposed in the rail part and configured to rotate about an axis parallel to the first direction; and a manipulation lever coupled to the steering part and the driving part and extending upward. The manipulation lever is configured to control the acceleration and deceleration of the vehicle by operating the driving part or control a rotation of the vehicle by operating the steering part.

First claim

What is claimed is:

1 . A steering and driving interface device mounted in a vehicle, the steering and driving interface device comprising:
a rail part fixed in the vehicle and elongated in a first direction; a driving part coupled to the rail part, wherein the driving part is configured to move in the first direction and control an acceleration and deceleration of the vehicle; a steering part disposed in the rail part and configured to rotate about an axis parallel to the first direction; and a manipulation lever coupled to the steering part and the driving part and configured to extend upward, wherein the manipulation lever is configured to:
control the acceleration and deceleration of the vehicle by operating the driving part, or
control a rotation of the vehicle by operating the steering part.

2 . The steering and driving interface device of claim 1 , wherein the manipulation lever comprises:
an upper stick part having a shape in which a pair of bars extending upward meet together and are connected to each other at lower ends thereof; and a lower stick part having one end connected to a lower end of the upper stick part, and another end coupled to the steering part.

3 . The steering and driving interface device of claim 2 , wherein the manipulation lever further comprises a hinge member provided between the upper stick part and the lower stick part and configured to be bent in the first direction.

4 . The steering and driving interface device of claim 1 , wherein the driving part comprises:
a sliding block coupled to the rail part and configured to reciprocate in the first direction; and a sliding sensing part disposed on the rail part or the sliding block and configured to sense a motion of the sliding block.

5 . The steering and driving interface device of claim 4 , wherein the driving part further comprises a sliding assistance part comprising:
a sliding worm wheel fixed to the sliding block; a sliding gear fixed to the rail part and coupled to the sliding worm wheel; and a sliding motor having a driving shaft coupled to a rotary shaft of the sliding gear.

6 . The steering and driving interface device of claim 4 , wherein the sliding sensing part comprises:
a sliding sensing rack disposed at an upper end of the rail part; and a sliding sensing wheel disposed on the sliding block and configured to rotate while coming into contact with the sliding sensing rack in accordance with a movement of the sliding block.

7 . The steering and driving interface device of claim 4 , wherein:
the rail part comprises support ends extending from an upper end of the rail part in a direction in which the support ends face each other, and the sliding block comprises sliding bearing pins provided on portions facing lower surfaces of the support ends.

8 . The steering and driving interface device of claim 4 , wherein:
the steering part is disposed in the sliding block, one end of the manipulation lever is coupled to a rotary shaft of the steering part, and another end of the manipulation lever protrudes upward from the sliding block.

9 . The steering and driving interface device of claim 8 , wherein:
the sliding block has a slit extending in a second direction intersecting the first direction, and the slit is formed in an upper surface of the sliding block from which the manipulation lever protrudes.

10 . The steering and driving interface device of claim 1 , wherein the steering part further comprises a steering torque angle sensor connected to a steering rotary shaft and configured to detect a rotational torque.

11 . The steering and driving interface device of claim 1 , wherein the steering part further comprises a steering assistance part comprising:
a steering worm wheel fixed to a steering rotary shaft; and a steering motor including a driving shaft coupled to the steering worm wheel.

12 . The steering and driving interface device of claim 1 , further comprising:
a controller configured to generate an instruction for operating the vehicle by receiving a driving signal in accordance with a motion of the manipulation lever, wherein the controller comprises:
a steering angle instruction generation part configured to generate a steering angle instruction by receiving a steering torque measured by a steering part; and
a road wheel actuator control part configured to turn a road wheel by receiving the steering angle instruction.

13 . The steering and driving interface device of claim 12 , wherein the controller further comprises a manipulation lever position control part configured to receive feedback of a steering angle value of the road wheel and transmit an instruction to the steering part.

14 . The steering and driving interface device of claim 1 , further comprising:
a controller configured to generate an instruction for operating the vehicle by receiving a driving signal in accordance with a motion of the manipulation lever, wherein the controller comprises:
a speed instruction generation part configured to generate a vehicle speed instruction by receiving a sliding stroke measured by a driving part; and
a vehicle speed control part configured to control a vehicle speed by receiving the vehicle speed instruction.

15 . The steering and driving interface device of claim 14 , wherein the controller further comprises a manipulation lever position control part configured to receive feedback of the vehicle speed and transmit an instruction to the driving part.

16 . A vehicle comprising:
a steering and driving interface device mounted in the vehicle, wherein the steering and driving interface device includes: a rail part fixed in the vehicle and elongated in a first direction; a driving part coupled to the rail part, wherein the driving part is configured to move in the first direction and control an acceleration and deceleration of the vehicle; a steering part disposed in the rail part and configured to rotate about an axis parallel to the first direction; and a manipulation lever coupled to the steering part and the driving part and configured to extend upward, and wherein the manipulation lever is configured to:
control the acceleration and deceleration of the vehicle by operating the driving part, or
control a rotation of the vehicle by operating the steering part.
