Description

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

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a button type electronic transmission system, and more particularly, to a button type electronic transmission system capable of mode conversion in an automatic mode and a manual mode.

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, and D stages). However, since the number of buttons is large in each of the speed change stages , The operation is inconvenient, and the layout is disadvantageous in particular due to a large number of buttons.

In addition, a general button type electronic speed change system has a disadvantage of high possibility of erroneous operation of the shift button due to operation of the same shift button in the automatic mode and the manual mode.

For example, the R-speed change button, N-shift button and D-shift button operated in the auto mode are used as the 1-speed shift button, the 2-speed shift button and the 3-shift button, respectively, in the manual mode, There is a disadvantage that the driver is likely to erroneously operate the shift button at the time of operation.

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.

Two manual mode switches 50c and 50d are disposed between the two auto mode switches 50a and 50b along the circumferential direction of the main housing 10 so that adjacent switches are arranged at regular intervals.

3, the shift button 40 rotates in the vertical direction with respect to the axis L1 of the hinge shaft 32. At this time, only the auto mode switches 50a and 50b are operated and the manual mode If the signals of the manual mode switches 50c and 50d are transmitted to the PCB 60 in the case of the auto mode, the PCB 60 can not recognize the abnormal situation at this time It is determined that there is no further shifting and the warning device is controlled to operate at the same time.

10, the shift button 40 is rotated in the left-right direction with respect to the axis L1 of the hinge shaft 32. At this time, only the manual mode switches 50c and 50d are operated and the automatic mode If the signals of the auto mode switches 50a and 50b are transmitted to the PCB 60 in the manual mode, the PCB 60 can not detect the abnormality at this time, It is determined that there is no further shifting and the warning device is controlled to operate at the same time.

[ And a return spring 54 for providing a return force to the upper cover 52 by the elastic force accumulated at both ends while being supported by the lower cover 51 and the upper cover 52.

When the shift button 40 is rotated with respect to the axis L1 of the hinge shaft 32 by the operation of the driver, the shift button 40 presses the upper cover 52, When the upper cover 52 is brought into contact with the speed change sensor 53, the speed change speed signal is outputted and the output speed change speed signal is outputted to the PCB 51. In this case, (60).

The shift sensor 53 is preferably a pressure sensor capable of outputting a signal upon contact with the upper cover 52, but is not limited thereto.

On the other hand, one of the two auto mode switches 50a and 50b is a switch for outputting the P-stage and R-stage signals, and the other is a switch for outputting the N-stage and D-stage signals.

For example, the auto mode switch 50a located on the upper side of the axis L1 of the hinge axis 32 in FIG. 3 is a switch for outputting the P stage and R stage signals, and the auto mode switch 50b Is a switch for outputting the N-stage and D-stage signals.

The auto mode switches 50a and 50b output an R-stage signal or an N-stage signal when the upper cover 52 momentarily contacts the speed change sensor 53. When the R-stage signal or the N- If the time for which the upper cover 52 is in contact with the speed change sensor 53 is long, a P-stage signal or a D-stage signal is output.

In contrast, when the upper cover 52 momentarily contacts the speed change sensor 53, the upper cover 52 outputs a P-stage signal or a D-stage signal, It may be configured to output the R-stage signal or the N-stage signal when the contact time with the sensor 53 is long.

One of the two manual mode switches 50c and 50d is a switch for outputting an UP SHIFT signal and the other is a switch for outputting a DOWN SHIFT signal.

For example, the manual mode switch 50c located on the left side of the axis L1 of the hinge shaft 32 in FIG. 10 is a switch for outputting an upshift signal, and the manual mode switch 50d located on the opposite right side A switch for outputting a downshift signal.

Conversely, the manual mode switch 50c located on the left side outputs the downshift signal, and the manual mode switch 50d located on the right side outputs the upshift signal.

A plurality of guide rods 11 formed in a flat plate shape protrude toward the center of the main housing 10 on the inner surface of the main housing 10, Two rod coupling grooves 51b are formed in which the rod 11 is fitted.

The guide rods 11 are composed of eight in total, and two pairs are arranged at intervals of 90 degrees.

In addition, the two rod-engaging grooves 51b are formed on the outer circumferential surface of the lower cover 51 so as to face each other at an interval of 180 degrees.

    Wherein when the speed change step signal is generated from the switch that does not match the axis among the auto mode switch and the manual mode switch, the change of the speed change stage is not progressed by the control of the PCB.
  16. 14. The method of claim 13,
    A step motor is fixedly installed on the main housing;
    Wherein the shift button receives the power of the step motor and rotates in the circumferential direction with respect to the main housing.
