Description

Shift control device for electronic shift system {SHIFT CONTROL APPARATUS FOR ELECTRONIC SHIFT SYSTEM}

The present invention relates to a shift control device for an electronic shift system, and more particularly, to a shift control device for an electronic shift system in which a button type and a lever type are combined.

In general, a vehicle equipped with an automatic transmission controls a hydraulic pressure within a shift range set according to a driving speed of the vehicle so that a transmission gear in a target shift stage range can be automatically operated.

An automatic transmission creates a gear ratio using a hydraulic circuit, a planetary gear, and friction elements to perform shifting, and a transmission control unit (TCU) is responsible for controlling these components.

The Shift By Wire (hereinafter referred to as SBW) system, an electronic shifting system for vehicles, is an electronic shifting system that does not have a mechanical connection structure such as a cable between the transmission and the shift lever, unlike conventional mechanical shift systems. Alternatively, when the sensor value generated when the button is operated is transmitted to the shift controller (TCU), the solenoid or electric motor is operated by the electronic signal commanded by the TCU, and the hydraulic pressure is applied to the hydraulic circuit for each gear shift by the operation of the solenoid or electric motor. This is a system in which shift control is performed electronically by being applied or blocked.

Therefore, the SBW-based automatic transmission transmits the driver's will to shift as an electrical signal to the TCU through simple manipulation of the electronic shift lever or button, thereby forward (D) and reverse (R), neutral (N) and parking (P). ) has the advantage of being able to operate the gear shift more easily with the range, etc., and also has the advantage of securing a wide space between the driver's seat and the front passenger's seat because the shift lever can be miniaturized.

On the other hand, in the electronic shift system, the lever type in which the shift operation is performed by the lever is similar to the mechanical shift lever, so it does not have a great advantage compared to the mechanical shift lever, and the space occupied by the console is still large, so the space for peripheral parts such as cup holders is still large. There is a disadvantage in that it is relatively small, and in particular, there is a disadvantage in that the body of a passenger may be injured when an accident occurs due to the protruding lever.

In addition, the button-type electronic shift system, in which the shift operation is performed with a button, is easier to operate than the lever type, and the console space can be usefully utilized as the installation location (centa fascia) can be changed to a location other than the console. , In the event of an accident, contact with the body of the passenger can be eliminated, which has the advantage of preventing injury to the passenger, but the number of buttons is large and the number of buttons is configured to operate different buttons for each shift stage (P, R, N, D). , It is inconvenient to operate, and there is a risk of misoperation due to the large number of buttons.

The matters described as the background art above are only for improving understanding of the background of the present invention, and should not be taken as an admission that they correspond to prior art already known to those skilled in the art.
