Abstract
A steering input device according to the present disclosure includes a grip part, a lower shaft engaged to the grip part and configured to be rotated by a rotation of the grip part, a torsion bar, an end portion of which is connected to the lower shaft, wherein the torsion bar is at least partially disposed in the lower shaft, a connection shaft connected to the torsion bar and configured to accommodate at least a part of the torsion bar, the connection shaft being connected to the lower shaft, a sensor configured to detect a rotation angle of the lower shaft or the connection shaft, and a motor shaft connected to the connection shaft and configured to be rotated by a motor.
Claims19
A steering input device comprising:
- a grip part;
- a lower shaft engaged to the grip part and configured to be rotated by a rotation of the grip part;
- a torsion bar, an end portion of which is connected to the lower shaft, wherein the torsion bar is at least partially disposed in the lower shaft;
- an upper shaft connected to the torsion bar and accommodating at least a part of the torsion bar, the upper shaft being connected to the lower shaft;
- a sensor configured to detect a rotation angle of the lower shaft or the upper shaft;
- and
- a motor shaft connected to the upper shaft and coupled to a motor to be rotated by the motor.
A method of controlling an electronic control steering system comprising a steering input device, a steering part engaged to the steering input device, and a controller electrically and communicatively connected to the steering input device and the steering part, the method comprising:
- detecting, by a sensor electrically and communicatively connected to the controller, a speed of a vehicle;
- determining, by the controller, whether the detected speed of the vehicle is equal to or higher than a preset speed;
- and
- setting, by the controller, a total gear ratio value to a first value upon concluding that the detected speed of the vehicle is equal to or higher than the preset speed, and setting, by the controller, the total gear ratio value to a second value, which is larger than the first value, upon concluding that the detected speed of the vehicle is lower than the preset speed,
- wherein the total gear ratio value is a ratio of a tire steering angle to a rotation angle of a grip part of the steering input device.
A steering input device comprising:
- a grip part;
- a connection part engaged to the grip part and configured to be rotated by a rotation of the grip part;
- an input part housing accommodating the grip part and the connection part;
- and
- a reaction force generation part coupled to the input part housing and configured to generate a reaction force that varies depending on the rotation of the grip part,
- wherein the reaction force generation part comprises:
- a guide bushing being in contact with the grip part and configured to be moved by the rotation of the grip part;
- and
- a restriction pin configured to restrict a movement range of the guide bushing.
