Description

Button type electronic transmission system {BUTTON TYPE ELECTRONIC SHIFT LEVER SYSTEM}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a button-type electronic speed-change system, and more particularly to a button-type electronic speed-change system that prevents a repeated operation of a button at the same speed- System technology.

Generally, a vehicle equipped with an automatic transmission controls a hydraulic pressure in a shift range set according to the running speed of the vehicle, so that the transmission of the target shift range is automatically operated.

Automatic transmissions use a hydraulic circuit, planetary gears and friction elements to create gear ratios to perform shifting, and control of these components is handled by a Transmission Control Unit (TCU).

Unlike a conventional mechanical transmission system, the Shift By Wire (SBW) system, which is an electronic transmission system for a vehicle, is an electronic transmission system having no mechanical connection structure such as a cable between a transmission and a shift lever, Or the sensor value generated when the button is operated is transmitted to the shift control unit TCU, the solenoid or the electric motor is operated by the electronic signal commanded by the TCU, and the hydraulic circuit of each shift range is operated by the solenoid or the electric motor, And the electronic control is performed electronically.

Therefore, the automatic transmission based on the SBW can transmit forward (D) and reverse (R), neutral (N), and parking (P) by transmitting the driver's shift intention to the TCU as an electric signal through a simple operation of the electronic shift lever or button. ) Range. Further, the shift lever can be downsized and a large space can be secured between the driver's seat and the passenger's seat.

On the other hand, in a lever type in which a shifting operation is performed by a lever in an electronic transmission system, the operation mode of the shift lever is similar to that of a mechanical type shift lever and there is no great advantage in comparison with a mechanical type. Further, space occupied by the console is still large, There is a disadvantage in that it may be injured by the contact of the passenger's body when an accident occurs due to the protruding lever.

In addition, the button type electronic transmission system that performs the shifting operation with the button is easier to shift than the lever type, and the installation position (centafascia) can be changed to a position other than the console, so that the console space can be utilized effectively , It is possible to eliminate the contact with the body of the passenger in the event of an accident, so that the passenger can be prevented from being injured.

However, in a button-type electronic shift system that operates the shift button individually for each of the speed change stages (P, R, N, D), when the driver operates the shift select button without looking directly at the eye, In this case, the driver is mistaken for not changing the speed change stages (P, R, N, and D stages), which causes a disconcerting feeling of the driver.

It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as an admission that the prior art is known to those skilled in the art.

The rotary plate 20 is formed as a circular plate and has a structure in which an area of more than a half circle is positioned outdoors with respect to the center fascia 2 so as to be obscured by the center fascia 2.

When the rotary plate 20 is formed of a circular plate, the rotary radius of the rotary plate 20 can be reduced compared to other rotary plates of a triangular shape or a rectangular or polygonal shape, thereby making it possible to construct a compact package.

When the rotary plate 20 is installed so as to be covered by the center fascia 2 in the outward direction with respect to the center fascia 2 in the outward direction with respect to the center fascia 2, It is possible to minimize the area of the rotary plate 20 exposed to the room when the rotary plate 20 is installed so as to be eccentrically positioned in the outdoor direction with respect to the vehicle body 2, It is possible to further improve it.

At least one window of the pair of windows 21 and 22 formed on the rotary plate 20 is positioned in the interior direction with respect to the center fascia 2 and is exposed to the outside when the rotary plate 20 rotates .

That is, since the shift button 10 is provided on the console surface 1 so as to be located in the indoor direction with respect to the center pedestal 2, when the driver operates the shift button 10 through the windows 21 and 22 At least one window must be located indoors with respect to the center fascia 2 at the time of rotation of the rotary plate 20 and a structure in which some of the transmission buttons 10 are exposed to the outside through a window positioned indoors .
