The present application claims priority to Korean Patent Application No. 10-2023-0018749, filed Feb. 13, 2023, the entire contents of which is incorporated herein for all purposes by this reference.
The present disclosure relates to a column-type electronic shift control apparatus, and more particularly, to a column-type electronic shift control apparatus mounted in a rotation type on a steering column.
In general, in vehicles provided with an automatic transmission, hydraulic pressure is controlled within gear stages set for the speed of the vehicles so that gears of desired shifting stages may be automatically operated.
An automatic transmission generates gear ratios using a hydraulic circuit, a planetary gear set, and friction members to shift and a Transmission Control Unit (TCU) is in charge of control of these components.
A Shift-By-Wire (SBW) system, which is an electronic shift system for a vehicle, has no mechanical connection structure such as a cable between a transmission and a shift lever, unlike existing mechanical shift systems. In the SBW system, when a sensor value generated by operation of a shifter (a shift lever or a shift button or a shift dial) is transmitted to a Transmission Control Unit (TCU), shift control is electronically performed in response to an instruction signal from the TCU.
Accordingly, an automatic transmission based on SBW includes an advantage that shifting into a Driving (D)-stage, a Reverse (R)-stage, a Neutral (N)-stage (Nd-stage or Nr-stage), etc. is more easily performed by transmitting driver's intention to shift to a Transmission Control Unit (TCU) using an electrical signal by simply operating an electronic shifter, and has another advantage that because the shifter may be formed in a small size, a wide area may be secured between the driver seat and the passenger seat.
As a method of shifting using an electronic shift system, in a broad meaning, there are a lever type using a lever, a button type using a button, and a dial type using a dial.
The information included in this Background of the present disclosure is only for enhancement of understanding of the general background of the present disclosure and may not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
Various aspects of the present disclosure are directed to providing a column-type electronic shift control apparatus which is mounted in a rotation type on a steering column of a vehicle and in which a shifter is positioned to extend upward in a standby mode and is positioned to extend laterally in a use mode by rotating from the standby mode ahead of the steering wheel in the visual field of a driver so that high-tech images may be provided and the commercial value may be improved.
Various aspects of the present disclosure are to provide a column-type electronic shift control apparatus configured to be able to shift by operating a shifter even in a standby mode when the shifter cannot be rotated to a use mode from a standby mode due to breakdown so that safety in shifting may be further reinforced.

A column-type electronic shift control apparatus according to exemplary embodiments of the present disclosure is described hereafter in detail with reference to the accompanying drawings.
A column-type electronic shift control apparatus according to various exemplary embodiments of the present disclosure, as shown in
Various exemplary embodiments of the present disclosure includes a configuration in which the shifter 200 which is operated by a driver to shift is disposed at the steering wheel 10 in a vehicle, and includes an advantage that there is no demand for providing a specific space for mounting the shifter 200.
The present disclosure is characterized in that a rotation axis S1 of the shifter 200 and a rotation axis S2 of the steering wheel 10 are disposed substantially in parallel. That is, various exemplary embodiments of the present disclosure includes a structure in which a steering column 20 passes through both the housing 100 and the first end portion of the shifter 200, the housing 100 is fixed to the steering column 20 ahead of the steering wheel 10, and the shifter 200 is rotated on the steering column 20.
In the case in which the steering column 20 passes through the first end portion of the shifter 200 and the shifter 200 may be rotated with respect to the steering column 20, as described above, the rotation axis S1 of the shifter 200 and the rotation axis S2 of the steering wheel 10 are substantially the steering column 20, and in the instant case, the external size may be reduced.
As an exemplary embodiment of the present disclosure, a structure in which the steering column 20 does not pass through the first end portion of the shifter 200 and the shifter 200 is disposed outside the steering column 20 is possible. For example, the rotation axis S1 of the shifter 200 and the rotation axis S2 of the steering wheel 10 may be spaced apart and substantially parallel with each other, and the present case has an advantage that it is possible to increase the degree of free designing because the shifter 200 may be provided at various positions, when necessary.
When the power mechanism 300 is operated, the shifter 200 is rotated on the steering column 20 and may be switched to a standby mode and a use mode when rotating.
The standby mode may be defined as a position at which the shifter 200 extends upward ahead of the steering wheel 10 in the visual field of a driver and the use mode may be defined as a position at which the shifter 200 laterally extends by rotating from the standby mode.
For example, the standby mode may be a position at which the shifter 200 extends in the direction of twelve o'clock and the use mode may be a position at which the shifter 200 extends in the direction of two o'clock or the direction of ten o'clock.
The standby mode and the use mode of the shifter 200 may be switched by operation of the power mechanism, and switching from the standby mode to the use mode may be set at 90 degrees or less 90 degrees.
When switching from the standby mode to the use mode of the shifter 200 is set at 90 degree or more and the shifter 200 is positioned over the direction three o'clock or before the direction of nine o'clock in the use mode, a knee of a driver may be interfered with by coming in contact with the shifter 200 at the position of the use mode. Accordingly, switching from the standby mode to the use mode of the shifter 200 may be set at 90 degree or less.
The shifter 200 is switched to the use mode from the standby mode by rotating clockwise or counterclockwise by operation of the power mechanism 300 and is returned to the standby mode by rotating in the opposite direction from the use mode.
That is, when the power mechanism 300 is operated, the shifter 200 may be switched to the use mode in the direction of two o'clock by rotating clockwise from the position of the standby mode in which the shifter 200 extends in the direction of twelve o'clock, or when the power mechanism 300 is operated, the shifter 200 may be switched to the use mode in the direction of ten o'clock by rotating in the opposite direction from the position of the standby mode in the direction of twelve o'clock.
Furthermore, the shifter 200 in the use mode may be returned to the position of the standby mode in the direction of twelve o'clock by rotating in the opposite direction by operation of the power mechanism 300.
When the shifter 200 is positioned at the use mode by rotating clockwise from the standby mode, as in
The power mechanism 300 that rotates the shifter 200 includes: a motor 310 fixed to the housing 100: a gear member 320 that transmits power of the motor 310 to the shifter 200; and a Printed Circuit Board (PCB) 330 that is configured to control driving of the motor 310.
The motor 310 may be a bidirectional motor that can rotate the shifter 200 both clockwise and counterclockwise.
The gear member 320 includes a worm 321 connected to the motor 310, a worm wheel 322 engaged with the worm 321, and an intermediate gear 323 coaxially connected to the worm wheel 322, and the shifter 200 is characterized in that it is self-locked and its position is fixed in the standby mode and the use mode by engagement of the worm 321 and the work wheel 322.
Self-locking means that the position of the shifter 200 is fixed in the standby mode or the use mode by engagement of the worm 321 and the worm wheel 322 even though power which is transmitted to the motor 310 is cut, and accordingly, there is an advantage that there is no demand for a specific stopper for fixing the position of the shifter 200.
A gear portion 210 is formed on the external surface of the first end portion of the shifter 200, the intermediate gear 323 and the gear portion 210 are engaged with each other, and rotation of the intermediate gear 323 is transmitted to the gear portion 210, whereby the shifter 200 is rotated.
The intermediate gear 323 shares a shaft with the worm wheel 322 and may be a spur gear or a spiral gear.
In
The motor support 311 is provided to be fixed to the housing 100 and the motor 310 is coupled to be fixed to the motor support 311.
A first end portion of the gear shaft 340 is fixed to the housing cover 110 and a second end portion of the gear shaft 340 passes through the center portion of the worm wheel 322, and the worm wheel 322 is rotated on the gear shaft 340.
A permanent magnet 350 is fixed to the gear member 320, the PCB 330 includes a Hall sensor 360 which is configured to detect rotation of the shifter 200 based on variation of magnetic flux of the permanent magnet 350 due to rotation of the gear member 320, and the PCB 330 is configured to control driving of the motor 320 using a signal of the Hall sensor 360.
The PCB 330 detects the position of the shifter 200 using a signal of the Hall sensor 360, whereby it is possible to know whether the shifter 200 is correctly positioned at the position of the standby mode or the use mode.
Furthermore, the PCB 330 is configured to control rotation of the shifter 200 by controlling driving of the motor 310, whereby the shifter 200 may be rotated to the use mode from the standby mode or to the standby mode from the use mode.
Furthermore, the Hall sensor 360 may be used for fail safe (breakdown control) when the shifter 200 is not correctly positioned at the position of the standby mode or the use mode.
According to an exemplary embodiment of the present disclosure, the shifter 200 includes an indicator 400.
A visual information image 410 excluding gear stages may be displayed on the indicator 400 when the shifter 200 is positioned at the standby mode, as in
The gear stages 420 of a vehicle that are displayed on the indicator 400 may be a D-stage, an N-stage, an R-stage, and a P-stage, and the visual information image 410 excluding gear stages, as shown in
The welcome image 411 is an image which is visually displayed when a driver gets in a vehicle, the goodbye image 412 is an image which is displayed when a driver get off a vehicle, the autonomous driving activation image 413 is an image that visually shows an autonomous driving activation state, and the driving assistant system activation image is an image that visually shows an activation state of a driving assistant system such as an ADAS (Advanced Driver Assistance System).
As described above, the current condition of a vehicle is displayed as a visual image on the indicator 400 and is provided to a driver under various conditions, whereby a commercial value may be improved.
Because the standby mode is a mode at which the shifter 200 extends upward, the shifter 200 is positioned at the front that a driver looks at when the driver gets in a vehicle, so that the visual image 410 excluding gear stages may be easily transmitted to the driver and an aesthetic sense may be aroused.
Because the use mode is a mode at which the shifter 200 laterally extends, when the shifter 200 is positioned at the use mode, a driver can easily hold the shifter 200 by hand and can more easily change gear stages.
The PCB 330 according to an exemplary embodiment of the present disclosure is configured to control the motor 310 to open when a signal is input through an input unit 500 and the signal from the input unit 500 is any one of vehicle on- and off-signals, door open and close signals, door lock and unlock signals, an autonomous driving mode change signal, and a manual driving mode change signal.
The vehicle on-signal of the signals from the input unit 500 includes a drivable state (EV ready) when the vehicle is an electric vehicle, whereby a driver can clearly recognize whether the electric vehicle is in the on-state.
The shifter 200 is positioned at the standby mode when a vehicle is in the off-state, and is positioned at the use mode when a vehicle is in the on-state, so it is possible to clearly recognize whether an electric vehicle is in the on-state based on the position change of the shifter 200.
Furthermore, the shifter 200 is positioned at the standby mode when a vehicle is in an autonomous driving mode, and is positioned at the use mode when a vehicle is in a manual driving mode.
It is assumed that a vehicle is in the on-state in the situation of the autonomous driving mode or the manual driving mode of the vehicle.
In an autonomous driving mode, a vehicle is being driven but the shifter 200 is positioned at the standby mode in the direction of twelve o'clock, and in the instant case, the autonomous driving activation image 413 is displayed on the indicator 400, so recognizability of the autonomous driving mode is improved.
When a door open signal or a door unlock signal is generated, the shifter 200 is positioned at the standby mode and the welcome image 411 is displayed on the indicator 400.
In a door open condition, the welcome image 411 is displayed on the indicator 400, whereby a satisfactory aesthetic sense may be provided to a driver.
The shifter 200 should be switched between the use mode and the standby mode, depending on signals from the input unit 500, and for example, the shifter 200 may be positioned at the standby mode when a door open signal is generated, and may be positioned at the use mode when a door close signal is generated.
Furthermore, the shifter 200 may be positioned at the standby mode when a door unlock signal is generated, and may be positioned at the use mode when a door lock signal is generated.
When the shifter 200 is positioned at the use mode, a driver can change gear stages by operating the shifter 200, and when the shifter 200 is operated at the standby mode position, gear stages cannot be changed or an N-stage shifting signal may be output for only a predetermined time period immediately after a vehicle is turned off.
In a manual driving mode situation, the shifter 200 is positioned at the use mode and a driver can change gear stages by operating the shifter 200.
A vehicle is in the off-state or is in an autonomous driving mode situation when the shifter 200 is positioned at the standby mode, so, in the instant case, gear stages are not changed for safety even though a driver operates the shifter 200.
Exceptionally, to park a vehicle in the N-stage, it may be possible to output an N-stage shifting signal for only a predetermined time period immediately after a vehicle is turned off when the shifter 200 is operated.
When the shifter 200 is positioned at the use mode, as in
That is, when a driver turns the shift knob 220 forward (in the direction of an arrow R1), a D-stage or an R-stage is selected, when a driver turns the shift knob 220 backward (in the direction of an arrow R2), the R-stage or the D-stage is selected, and when a driver turns the shift knob 220 forward or backward and then releases the shift knob 220, the shift knob 220 is returned to the initial position by a restoring force of an elastic member such as a spring. The initial position, for example, may be a Null stage at which a specific signal is not generated.
As an exemplary embodiment of the present disclosure, it may be possible to change gear stages by rotating the shifter 200 itself in the use mode.
That is, when a driver rotates the shifter 200 itself upward (in the direction of an arrow R3), a D-stage or an R-stage is selected, when a driver rotates the shifter 200 itself downward (in the direction of an arrow R4), the R-stage or the D-stage is selected, and when a driver rotates the shifter 200 upward or downward and then releases the shifter 200, the shifter 200 is returned to the initial position by a restoring force of an elastic member such as a spring.
Furthermore, according to an exemplary embodiment of the present disclosure, a P-stage button 600 is separately disposed at the end portion of the shifter 200, so it is possible to park a vehicle by operating the P-stage button 600.
The shifter 200 according to an exemplary embodiment of the present disclosure may include a shift controller 700 that detects a change of gear stages by operation of the shifter.
The shift controller 700 is disposed and fixed in the shifter 200, the shift controller 700 and the PCB 330 are connected to each other to transmit and receive signals through a wiring 710, and the shift controller 700 can make the visual information image 410 excluding gear stages be displayed on the indicator 400 in the standby mode and can make the gear stages 420 of a vehicle be displayed on the indicator in the use mode in response to signals received from the PCB 330.
That is, when a driver operates the shift knob 220, the shift controller 770 detects a change of gear stages and transmits gear stage change information to the PCB 330 and the PCB 330 transmits the present information to a vehicle controller, whereby shifting is finished. Furthermore, the vehicle controller is configured to transmit a shift finishing signal to the PCB 330 in consideration of shift conditions, the PCB 330 transmits shift finishing information back to the shift controller 700, and finally, the information of a changed gear stage 420 is displayed on the indicator 400 by the shift controller 700.
It may be possible to define a configuration in which the PCB 330 in the housing 100 is a main PCB, the shift controller 700 in the shifter 200 is an assistant PCB, and the main PCB and the assistant PCB are electrically connected to each other through the wiring 710.
The present disclosure, which relates to a column-type electronic shift control apparatus which is mounted on a steering column 20 of a vehicle, is characterized by including: a shifter 200 selecting gear stages of a vehicle; and a power mechanism 300 transmitting power to rotate the shifter 200 in response to a signal from an input unit 500, and is characterized in that the shifter 200 is positioned at a standby mode which is a mode at which the shifter 200 extends upward or is positioned at a use mode which is a mode at which the shifter 200 laterally extends in the visual field of a driver ahead of a steering wheel 10, and the shifter 200 is switched to the use mode from the standby mode by rotating clockwise or counterclockwise and is returned to the standby mode from the use mode by rotating in the opposite direction by operation of the power mechanism 300 when signals are input from an input unit 500.
As described above, because the column-type electronic shift control apparatus according to an exemplary embodiment of the present disclosure is mounted in a rotation type on the steering wheel 20 of a vehicle so that the shifter 200 is positioned to extend upward in the standby mode and is positioned to extend laterally in the use mode by rotating from the standby mode in the visual field of a driver ahead of the steering wheel 10, high-tech images may be provided, so there is an advantage that the commercial value may be improved.
Furthermore, because the column-type electronic shift control apparatus is configured to be able to shift by operating the shifter 200 even in the standby mode when the shifter 200 cannot be rotated to a use mode from a standby mode due to breakdown, there is an advantage that safety in shifting may be further reinforced.
