A dial transmission lever device according to an exemplary embodiment of the present invention includes a dial knob, a button guide unit, a plurality of button units, a rubber unit, and a board unit. The dial knob is rotatable from a predetermined reference position and includes a first hole that penetrates the dial knob from one end to the other end of the dial knob. The button guide unit is disposed in the dial knob. The plurality of button units is disposed in the button guide unit. The rubber unit is disposed below the button guide unit and includes protruding portions disposed below the plurality of button units, respectively. The board unit is disposed below the rubber unit. In addition, the dial knob further includes a rotary member disposed in the first hole, coupled to the dial knob, and configured to rotate together with the dial knob.

A transmission for a vehicle includes a knob configured to be rotated to select one of a plurality of shift stages; a driving unit for controlling rotation of the knob; and a shift controller for applying an electrical current to generate a torque in the driving unit. The driving unit comprises: a magnetic field generator; a magnetization unit including a plurality of magnetic bodies arranged at regular intervals along a circumference of the magnetic field generator; and a magnet unit including at least one pair of magnetic poles arranged along a circumference of the magnetization unit, wherein the magnetization unit or the magnetization unit is coupled with the knob and rotates integrally with the knob. A first mode allows the rotation of the knob and a second mode prevents the rotation of the knob depending on an intensity of a magnetic field generated by the magnetic field generator.

A vehicle transmission includes a shift lever including a receiving unit formed therein, a bullet in which at least a portion thereof is inserted and disposed within the receiving unit of the shift lever, and a detent groove unit which allows the bullet to advance or retreat depending on a profile of a contact surface in contact with the bullet as the shift lever rotates. The bullet includes a guide aperture formed longitudinally along an advancement-retreat direction of the bullet, and a fixing pin having at least one end thereof fixed to the receiving unit is inserted into the guide aperture.

The present invention improves fuel efficiency of a vehicle and decreases a noise, by decreasing a margin value of a hydraulic pressure supplied to a hydraulic pressure control target and decreasing the hydraulic pressure supplied to the hydraulic pressure control target, when the vehicle is driven automatically. In a hydraulic pressure control device 1 for a vehicle that controls a line pressure or an operation pressure (hydraulic pressure) supplied to a clutch 40 or a transmission 41 (hydraulic pressure control target) provided in the vehicle, the hydraulic pressure control device 1 includes an operation pressure control unit 10 (hydraulic pressure setting device) that sets margin values 1 and 2 of the operation pressure (line pressure) supplied to hydraulic circuits 31 and 31 of the clutch 40 or the transmission 41, on the basis of a predetermined driving plan (refer to FIG. 2) in the case of driving the vehicle automatically.

An actively restorable gear shifting device and a gear shifting method using the same are provided. The gear shifting device includes a gear shifting lever unit that is moved from an initial position to an operating position by external operating force and is connected to a restoring mechanism to be restored to the initial position when the operating force is eliminated. A driving gear is connected to the gear shifting lever unit to be rotated by a motion of the gear shifting lever unit. A driven gear engages with an outer tooth portion of the driving gear, connects to a gear shifting cable, and implements gear shifting by pushing or pulling the gear shifting cable by a rotation of the driving gear. The gear shifting lever unit is connected to the driving gear by a pawl, and the pawl has a first joining position and a second joining position.

A selector apparatus comprises a shift lever operably supported on a base for movement between gear positions, and a feel positioner mechanism with offset detent members, where a first detent engages first undulations for biasing the shift lever toward a center of a selected gear position from a first direction, and a second detent engages second undulations for biasing the selector lever toward the center of the selected gear position from a different second direction to the common center point. By the arrangement, the first and second undulations define opposing angled slopes toward the common center point. This allows the undulations to be designed to provide any desired level of biasing force toward the center point without the limitations of a single undulation defining the center point.

In a shift device, a lever is able to slide in a front-rear direction relative to a housing, and an FFC electrically connects a sensor substrate of the housing to an operating substrate of the lever. Here, the lever is moved slidingly in the front-rear direction, which is on a perpendicular direction side relative to a width direction of the FFC. Because of this, a reduction in the durability of the FFC can be inhibited.

In a shift device, as a result of lower sliding projections of a lever moving slidingly against lower sliding plates of soft materials, the slidability of the lever is improved. Moreover, as a result of restricting projections of the lever being abutted against stoppers of the soft materials, noise generated when a sliding motion of the lever is restricted is reduced. Additionally, because the lower sliding plates and the stoppers are formed integrally with each other, the structure can be simplified.
