Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a button type electronic type shift lever,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic shift lever of a vehicle and a control method thereof, and more particularly to a button-type electronic shift lever in which a currently selected gear range is displayed on a display unit and the remaining shift ranges are displayed on first to third buttons, And a control method.

Generally, a transmission is a device that transmits the power generated by an engine to a driving wheel by changing a rotational force and a speed so as to be suitable for a driving state of a vehicle, and is classified into a manual transmission and an automatic transmission.

The driver who operates the vehicle can change the speed change stage of the manual transmission or the automatic transmission to the desired speed change stage by operating the shift lever mounted on the console surface or the handle around the driver's seat.

The manual transmission is operated in such a manner that when a driver selects a gear corresponding to the running condition of the vehicle using a shift lever, the driver transmits a desired motion to the transmission through a cable or a rod. In the automatic transmission, if the driver moves the shift lever, The driver operates the inhibitor switch to transmit the desired motion to the transmission.

In particular, in recent years, an electronic shift lever has been increasingly used instead of a mechanical shift lever, in which a mechanical connection structure between a transmission and a shift lever is replaced with an electrical connection structure through an actuator and an ECU.

Unlike the mechanical shift lever, the electronic shift lever is not provided with a mechanical cable connection structure and has a disadvantage of having a position sensor portion for converting the shift position of the driver into an electronic signal. However, it has an excellent lever operation force and operation feeling, .

The electronic type shift lever includes a lever-type electronic shift lever that operates the electronic shift lever protruded on the console surface of the vehicle as a front and a back, a cylindrical electronic shift lever mounted on the console surface of the vehicle, Type electronic shift lever, a column-type electronic shift lever that operates the electronic shift lever mounted on the handle side of the vehicle up and down, and a button-type electronic shift lever that operates the button of the shift position of the vehicle by pressing the button.

Particularly, the conventional button type electronic type shift lever has an advantage of being simple and intuitive to operate. However, since the P-stage, R-stage, N-stage and D-stage buttons must be displayed in a limited space of the shift lever, There are disadvantages.

As a result, when the driver presses the button for changing the speed change stage, the two buttons are pressed at the same time frequently, and the driving stability of the vehicle is greatly reduced due to such erroneous operation.

In addition, when the interval between the buttons is widened to prevent the erroneous operation as described above, the space occupied by the shift lever becomes excessively large, which results in a problem of insufficient space for installing the storage space or another button performing a specific function.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems, and it is an object of the present invention to provide a speed change control apparatus and a control method thereof, in which a selected gear range is displayed on a display unit, And to provide a button-type electronic shift lever and a control method thereof that improve visibility and aesthetics inside the vehicle.

Further, since the number of the buttons is reduced by one compared to the conventional button-type electronic shift lever, the production cost of the vehicle is greatly reduced, and the size of the button can be configured in a limited space, thereby increasing the operability of the shift lever.

In addition, since the size of the button and the interval between the buttons are formed to be large and wide to clearly recognize the gear position, the visibility of the button is greatly improved. If the button is formed to have the same size as the conventional button, The size of the lever is reduced, so that it is possible to further enlarge the space in which the cup holder and the like can be housed.

Furthermore, the first to third buttons are sequentially displayed in the order of the P, R, N, and D gear stages excluding the gear stage indicated on the display unit, so that even if the gear stage is changed, The shift lever can be operated in the environment. That is, the buttons are always arranged in P-step, R-step, N-step and D-step so that the driver can clearly recognize the position of each gear position.
