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 in which an operation mode is changed for each shift button, Button type electronic transmission system.

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 (P, R, N, D), it is possible to prevent the passengers from injuring the passengers by avoiding contact with the passenger's body when an accident occurs. However, There is a disadvantage that an erroneous operation may occur in a situation in which the driver operates the shift button without directly looking at the shift button.

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.
