Description

TECHNICAL FIELD

[0001] The present disclosure relates to a ball-type shift control device for an electronic shift system, and more particularly, to a ball-type shift control device including a shift operation unit provided on a first hemisphere of the shift control device and a design unit for indirect illumination provided on a second hemisphere of the shift control device, wherein the shift operation unit and the design unit are configured to change positions by 180 degrees of rotation. BACKGROUND

[0002] Generally, a vehicle equipped with an automatic transmission controls hydraulic pressure within a preset shift range according to a driving speed of the vehicle, thereby enabling the transmission to automatically shift to a target gear.

[0003] An automatic transmission uses a hydraulic circuit, a planetary gear, and a friction element to provide a gear ratio for shifting, and these components are controlled by a transmission control unit (TCU).

[0004] Unlike existing mechanical shift systems, a shift by wire (hereinafter referred to as "SBW") system, which is an electronic shift system of a vehicle, is a type of electronic shift system in which there is no mechanical connection structure such as a cable between a transmission and a shift control device (e.g., a lever, a button, or a knob). The shift by wire system electronically performs shift control in such a manner that, when a signal generated upon operating the shift control device is transmitted to a transmission control unit (TCU), a transmission actuator (e.g., a shift cable motor or a select cable motor) operates in response to an electronic signal commanded by the TCU to apply or block hydraulic pressure to a hydraulic circuit for each gear.

[0005] Accordingly, an advantage of an SBW-based automatic transmission is that a shift intention of a driver is transmitted to the TCU as an electric signal by simply operating an electronic shift control device, thereby more easily shifting to a D range, an R range, a neutral (Nd or Nr) range, etc. In addition, an advantage of the SBW-based automatic transmission is that it is possible to miniaturize the shift control device and secure a spacious space between a driver's seat and a front passenger's seat.

[0006] The above is only for helping to understand the background of the present disclosure and does not mean that the present disclosure falls within the scope of the prior art known to those skilled in the art. SUMMARY

[0042] Hereinafter, a ball-type shift control device for an electronic shift system according to a preferred embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

[0043] As Figures 1 to 9As illustrated in the accompanying drawings, a ball-type shift control device for an electronic shift system according to the present disclosure includes a housing 10, a ball mechanism 20 rotatably coupled to the housing 10, and a power mechanism 30 that provides rotational power to rotate the ball mechanism 20 relative to the housing 10.

[0044] The housing 10 is located around a driver's seat and is fixedly installed to a console, a center fascia, etc. that the driver's hands can reach.

[0045] The ball mechanism 20 has a rotation shaft 40 coupled through the center of the ball mechanism 20 and is rotatable relative to the housing 10.

[0046] Accordingly, when the rotation shaft 40 is rotated, the ball mechanism 20 also rotates together relative to the housing 10, in which case the first hemisphere of the ball mechanism 20 is exposed to the vehicle interior through the housing 10, while the second hemisphere of the ball mechanism 20 remains in a state of being hidden in the housing 10.

[0047] The ball mechanism 20 includes a shift operation unit 50 provided on the first hemisphere of the ball mechanism 20 and a design unit 60 provided on the second hemisphere of the ball mechanism 20.

[0048] When the ball mechanism 20 is rotated relative to the housing 10, the shift operation unit 50 or the design unit 60 is exposed to the vehicle interior, while the other remains in a state of being hidden in the housing 10.

[0049] The shift operation unit 50 is provided with a shift mechanism 70 configured to be operated by a driver (i.e., a person) of the vehicle to shift gears. The shift mechanism 70 can be a shift knob 71 as illustrated in Figures 1 to 4 , a shift button 72 as illustrated in Figure 5 , or a shift lever 73 as illustrated in Figure 6 .

[0050] Here, when the shift mechanism 70 is the shift knob 71 or the shift lever 73, a separate P range button 74 can be provided on the shift mechanism 70.

[0051] One of the R range, the N range, and the D range can be selected by operating the shift knob 71, and the P range can be selected by pressing the separate P range button 74.

[0052] The shift button 72 can be operated in a manner that the driver selects and presses one of the P range button, the R range button, the N range button, and the D range button.

[0053] The driver can select one of the R range, the N range, and the D range by rotating the shift lever 73, and select the P range by pressing the separate P range button 74.

[0054] In an embodiment of the disclosure, the ball-type shift control device can further include a first printed circuit board (PCB) 90 that receives an operation signal from the shift mechanism 70 and outputs a control signal to a transmission control unit (TCU) 80. The first PCB 90 can be fixedly installed in the ball mechanism 20 to face the shift mechanism 70.

[0055] When receiving the operation signal from the shift mechanism 70, the first PCB 90 transmits the signal to the transmission control unit 80 so that the transmission actuator operates in response to the signal commanded by the transmission control unit (TCU) to apply or block hydraulic pressure to the hydraulic circuit of each gear, thereby electronically performing shift control.

[0056] The design unit 60 includes a light source 100 coupled to the first PCB 90 and turned on / off by control of the first PCB 90, and an illumination window 110 having a specific shape pattern 111 formed on a surface of the illumination window 110 to achieve indirect illumination when the light source 100 is turned on.

[0057] The light source 100 mounted on the first PCB 90 is an LED light source. When the light source 100 is turned on, the light source 100 can achieve indirect illumination (ambience light, ambient light), and in particular, the light source 100 can provide a welcome function in response to a user's gesture.

[0058] The illumination window 110 can be made of a semi-spherical tempered glass, and can be a transparent window or a translucent window that transmits light from the light source 100.

[0059] The design unit 60 can further include a scattering member 120 for scattering light from the light source 100. The scattering member 120 can be coupled to the illumination window 110 to face the light source 100, and as an example, the scattering member 120 can be a prism.

[0060] As shown in Figure 8 The design unit 60 can further include a display 130 that transmits a specific image through the illumination window 110.

[0061] Since an image set by a user is transmitted through the display 130, visibility can be further increased.

[0062] The display 130 can be fixedly installed in the illumination window 110 or the scattering member 120, and the operation of the display 130 can be controlled by the first PCB 90.

[0063] The power mechanism 30 includes a motor 31 fixedly installed in the housing 10, a plurality of gear members 32 interconnecting the motor 31 and the rotation shaft 40 to transmit power from the motor 31 to the rotation shaft 40, and a second PCB 33 fixed to the housing 10 to control the operation of the motor 31.

[0064] When receiving a signal from the input unit 140, the second PCB 33 controls to drive the motor 31. The signal from the input unit 140 can be one of a vehicle start switch on / off signal, a vehicle door open / close signal, a vehicle door unlock / lock signal, a driving mode change signal (automatic driving mode and manual driving mode change signal), and an operation switch on / off signal.

[0065] When receiving a signal from the input unit 140, the second PCB 33 controls to drive the motor 31, and power from the motor 31 is transmitted to the rotation shaft 40 through the gear members 32, so that the rotation shaft 40 rotates with respect to the housing 10 and the spherical mechanism 20 also rotates with the rotation shaft 40.

[0066] The spherical mechanism 20 is configured such that the rotation shaft 40 rotates 180 degrees when the power mechanism 30 is operated once. Therefore, when the spherical mechanism 20 rotates, the shift operation unit 50 is exposed to the vehicle interior through the opening of the housing 10, as shown in Figures 1 to 6 or the design unit 60 is exposed to the vehicle interior through the opening of the housing 10, as shown in Figure 7 and Figure 8

[0067] The second PCB 33 is provided with a Hall sensor 150 for detecting the rotation of the rotation shaft 40. Therefore, the second PCB 33 can more accurately control the driving of the motor 31 based on a signal from the Hall sensor 150.

[0068] That is, the first gear 161 is integrally coupled to one end of the rotation shaft 40, the first gear 161 is connected to the second gear 162 in an external engagement form, a central shaft of the second gear 162 is fixedly installed in the housing 10, the second gear 162 is coupled with a permanent magnet 163, and the Hall sensor 150 is provided in the second PCB 33 to face the permanent magnet 163.

[0069] ​Accordingly, when the first gear 161 and the second gear 162 rotate as the rotation shaft 40 rotates and the position of the permanent magnet 163 is changed by the rotation of the second gear 162, the Hall sensor 150 can detect a change in the magnetic field strength according to a change in the rotational position of the permanent magnet 163, and the second PCB 33 can control the motor 31 to terminate the driving of the motor 31 based on a signal from the Hall sensor 150.

[0070] Figure 9 A ball-type shift control device including a spherical mechanism formed to have three planes according to another embodiment of the disclosure is illustrated.

[0071] That is, the ball-type shift control device includes a spherical mechanism 520 having a rotation shaft 510 coupled through the center of the spherical mechanism 520, and a housing 530 to which the spherical mechanism 520 is rotatably coupled by the rotation shaft 510.

[0072] The spherical mechanism 520 has a first plane 521, a second plane 522, and a third plane 523 formed on the surface of the spherical mechanism 520, and the first plane 521 to the third plane 523 are continuously connected to each other to form a triangle. The spherical mechanism 520 is disposed such that the first plane 521 is provided with a shift mechanism 540 configured to be operated by a driver to shift, the second plane 522 is provided with a light source 550 that implements indirect illumination, and the third plane 523 is provided with a display 580 that transmits a specific image through an illumination window 570.

[0073] The ball-type shift control device further includes a first PCB 590 that receives an operation signal from the shift mechanism 540 and outputs a control signal to a transmission control unit (TCU), and a second PCB 600 that controls the light source 550 to turn on / off and controls the operation of the display 580.

[0074] The first PCB 590 and the second PCB 600 are both fixedly coupled to the spherical mechanism 520.

[0075] The spherical mechanism 520 can be rotated by using a power mechanism of the same motor as described above. To this end, the ball-type shift control device further includes a motor 610 fixed to the housing 530 and connected to the rotation shaft 510 to rotate the rotation shaft 510. The driving of the motor 610 can be controlled by the first PCB 590 or the second PCB 600.

[0076] As another example, the spherical mechanism 520 can be rotated about the rotation shaft 510 by manual operation of the driver.

[0077] The shift mechanism 540 can be one of a shift knob, a shift button, and a shift lever.

[0078] In the ball-type shift control device having the above-described structure, the ball mechanism 520 rotates 120 degrees around the rotation shaft 510. Therefore, when the ball mechanism 520 rotates, only one of the shift mechanism 540 provided on the first plane 521, the light source 550 provided on the second plane 522, and the display 580 provided on the third plane 523 is exposed to the vehicle interior through the opening of the housing 530, while the other two remain hidden in the housing 530.

[0079] As described above, the ball-type shift control device according to the present disclosure is provided such that the shift operation unit 50 configured to be operated by the driver to shift is provided at one hemisphere (e.g., the first hemisphere) of the ball mechanism 20 and the design unit 60 for indirect illumination and image transfer is provided at the other hemisphere (e.g., the second hemisphere). The ball-type shift control device is advantageous in that, by rotating the ball mechanism 20, when shift operation is required, only the shift operation unit 50 is exposed to the vehicle interior through the opening of the housing 10, while when shift operation is not required, only the design unit 60 is exposed to the vehicle interior through the opening of the housing 10, so that stability can be improved by improving visual recognition and marketability can be improved by high-tech imaging.

[0080] Although the preferred embodiments of the present disclosure have been described for illustrative purposes, those skilled in the art will recognize that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the present disclosure disclosed in the appended claims.
