Description

Technical Field

[0001] The present invention relates to an electronic shift control device, and more specifically, to an electronic shift control device that can prevent misoperation when the driver shifts gears and minimize vibration transmitted from the tactile motor to the main housing by transmitting tactile signals (tactile sensation signals) to the driver when the driver shifts to a specific shift gear by rotating the shift dial. Background Technology

[0002] Typically, in vehicles equipped with automatic transmissions, the gears for the desired gear shift are operated automatically by controlling hydraulic pressure within the shift gears set for the vehicle speed.

[0003] Automatic transmissions use hydraulic circuits, planetary gear sets, and friction components to generate gear ratios for shifting, and these components are controlled by the transmission control unit (TCU).

[0004] Unlike existing mechanical shifting systems, the Shift-by-Wire (SBW) system, which is an electronic shifting system in vehicles, does not have a mechanical connection structure such as a cable between the transmission and the shift lever. In an SBW system, when sensor values ​​generated by the operation of the electronic shift control device (shift lever or shift button) are transmitted to the TCU, electronic signals from the TCU operate solenoid valves or electric motors, applying or de-applying hydraulic pressure to the hydraulic circuit of each gear, thereby electronically controlling the shifting.

[0005] Therefore, automatic transmissions based on the SBW system have the following advantages: they can easily switch to D (driving), R (rear), and N (Nd or Nr) gears by simply operating the electronic shift control device (shift lever, button, or dial) to transmit the driver's shifting intention to the transmission control unit (TCU) using electrical signals; and they have another advantage, namely, since the shift control device can be formed in a small size, a wide area can be ensured between the driver's seat and the passenger seat.

[0006] There are three main types of gear shifting methods using electronic shifting systems: shift lever type (using a shift lever), button type (using a button), and dial type (using a dial).

[0007] The information disclosed in the background section of this invention is only for enhancing the understanding of the general background of this invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0008] Various aspects of the present invention aim to provide an electronic shift control device having a shift dial operated by the driver to select R, N (Nd or Nr) and D gears; and a P (Park) button operated by the driver to select P (Park) gear. The object of the present invention is to improve safety by transmitting a tactile signal to the driver when shifting to a specific gear by rotating the shift dial.

[0009] Various aspects of the present invention are designed to increase the intensity of the tactile signal transmitted to the shift paddle, thereby allowing the driver to more clearly identify the tactile signal by minimizing vibrations transmitted from the tactile motor to the main housing.

[0010] To achieve the objectives of this invention, an electronic shift control device includes: a shift dial rotatable relative to a main housing for selecting one of the vehicle's shift gears during rotation; a rotating body connected to the shift dial to rotate with it; a slotted plate connected to the rotating body to rotate with it; a printed circuit board (PCB) fixed to the main housing and outputting a shift gear signal selected by the shift dial to a transmission control unit (TCU) electrically connected to the PCB; and a tactile motor assembly fixed to the main housing, connected to the slotted plate, controlled by the PCB for operation, and generating a tactile signal during operation.

[0011] The tactile signals generated by the tactile motor assembly can be transmitted to the driver's hand operating the shift dial via the slot plate, rotating body, and shift dial.

[0012] When operating the shift dial, the selected gear can be any of R, N, or D.

[0013] The electronic shift control device may further include: a sensing gear rotatably coupled to the main housing and engaged with a rotating body; and a magnet engaged with the sensing gear, wherein the PCB can output a shift position signal of any one of R, N, and D gears based on the change in magnetic flux caused by the change in the position of the magnet when the shift dial is rotated.

[0014] The electronic shift control may further include a P-gear button, which is located in the center of the shift dial and is movable up and down relative to the shift dial in response to a driver pressing it, wherein the PCB can recognize the contact of the P-gear button and generate a P-gear signal when the P-gear button is operated.

[0015] The haptic motor assembly may include: a motor housing fixed to a main housing; a haptic motor inserted into and fixed within the motor housing, electrically connected to a PCB and controlled by the PCB for operation; and a roller rotatably coupled to the motor housing and in contact with a slot plate.

[0016] The PCB can only operate the tactile motor when the shift signal selected when operating the shift dial matches the actual shift signal of the transmission fed back by the TCU.

[0017] When the shift dial is operated and the R position is selected, the haptic motor can be controlled by the PCB to operate and generate haptic signals.

[0018] The tactile signals generated by the tactile motor can be transmitted to the shift dial through the motor housing, rollers, slotted plate and rotating body, and the tactile signals transmitted to the shift dial can be transmitted to the driver's hand that operates the shift dial.

[0019] An elastic protrusion protruding in one direction can be integrally formed on the motor housing, and the motor housing can make line contact or point contact with the main housing through the elastic protrusion.

[0020] The elastic protrusion can protrude in the opposite direction of the roller, and when the elastic protrusion contacts the main housing, the elasticity of the elastic protrusion can apply a force to the motor housing to move the motor housing toward the slot plate, thereby maintaining the contact force between the roller and the slot plate.

[0021] The housing cover can be attached to the bottom of the motor housing, the vibration isolation pad can be attached to the housing cover, and the motor housing can be connected to the main housing via the vibration isolation pad.

[0022] The shell ribs can protrude from the main shell, and the vibration isolation pads can contact the shell ribs.

[0023] Haptic motors can be applied to all electronic shift control devices, including shift lever type which allows users to shift gears by operating a shift lever; button type which allows users to shift gears by operating a shift button; column type where the shift lever is mounted on the steering column; and toggle type which allows users to shift gears by operating a toggle switch.

[0024] An electronic shift control device according to various exemplary embodiments of the present invention includes a shift dial operated by a driver to select R, N (Nd and Nr) and D gears; a P gear button operated to select P gear; and a tactile motor that generates a tactile signal. Therefore, when the driver shifts to a specific gear (R) of the vehicle by operating the shift dial, the tactile motor is activated and a tactile signal (tactile sensation signal) is transmitted to the driver, thereby preventing accidental operation by the driver during gear shifting. Thus, it has the effect of improving safety.

[0025] Furthermore, since the vibration of the tactile motor transmitted to the main housing can be minimized by the vibration isolation pads disposed between the main housing and the motor housing, the strength of the tactile signal transmitted to the shift paddle can be increased. Therefore, this allows the driver to more clearly recognize the tactile signal.

[0044] The following describes in detail, with reference to the accompanying drawings, an electronic shift control device according to an exemplary embodiment of the present invention.

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown in Figures 7A, 7B, 8A, and 8B, an electronic shift control device according to various exemplary embodiments of the present invention includes: a main housing 10 fixed inside a vehicle; a shift dial 20 operated by a driver to rotate relative to the main housing 10 and to select any of the vehicle's shift gears during rotation; a rotating body 30 coupled to the shift dial 20 to rotate together; a slotted plate 40 coupled to the rotating body 30 to rotate together; a printed circuit board (PCB) 50 fixed to the main housing 10 and outputting a signal indicating the shift gear selected by the shift dial 20; and a tactile motor assembly 60 fixed to the main housing 10, connected to the slotted plate 40, controlled by the PCB 50 to operate, and generating a tactile signal during operation.

[0046] The main housing 10 can be fixed to the vehicle body near the driver's seat, such as the console, central dashboard, etc., but the installation position can be changed if necessary.

[0047] The shift dial 20 is configured as an integrated assembly of an upper dial 21 and a lower dial 22. The upper dial 21 includes light-transmitting glass, and light emitted from light-emitting diodes (LEDs) is exposed to the outside through the glass upper dial 21, thereby making the electronic shift control device more aesthetically pleasing.

[0048] In the electronic shift control device according to various exemplary embodiments of the present invention, the LED is electrically connected to the PCB 50, such that the LED is controlled by the PCB 50 to turn on or off.

[0049] The rotating body 30 is integrally connected to the bottom of the shift dial 20 and extends downward from the shift dial 20. When the driver operates the shift dial 20, the shift dial 20 and the rotating body 30 rotate together clockwise or counterclockwise relative to the main housing 10.

[0050] The rotating body 30 is connected to the lower dial 22 of the shift dial 20.

[0051] The groove plate 40 is annular in shape and has an arc-shaped groove formed circumferentially on its outer surface. It is integrally connected to the rotating body 30 and rotates together with the rotating body 30.

[0052] The PCB 50 is located below the slot plate 40, fixed to the main housing 10, and electrically connected to the vehicle's power source (battery) to be powered.

[0053] PCB 50 is configured to output the shift gear signal selected when the shift dial 20 is operated to the transmission control unit (TCU) 70, and its function of controlling the operation of the haptic motor 62 will be described below. The frequency, intensity, and number of vibrations generated by the haptic motor 62 can be controlled and varied by PCB 50.

[0054] According to various exemplary embodiments of the present invention, the tactile signal generated by the tactile motor assembly 60 is transmitted to the shift dial 20 via the slot plate 40 and the rotating body 30, and ultimately to the driver's hand operating the shift dial 20. Therefore, the driver receives the tactile signal (tactile sensation signal), thereby maximizing the driver's recognition of gear shifting.

[0055] When the shift dial 20 is operated according to various aspects of the present invention, the selected vehicle shift gear is one of R, N (Nd and Nr) and D.

[0056] The slot plate 40 is connected to the rotating body 30 to rotate together. The slot of the slot plate 40 contacts the detent assembly 80 with a leaf spring, and the detent assembly 80 is fixed to the main housing 10.

[0057] When the shift dial 20 rotates, an operating sensation is generated through the contact between the slot plate 40 and the stop assembly 80. When the operating force applied by the driver is removed from the rotating shift dial 20, the rotating shift dial 20 returns to its initial position due to the elasticity of the stop assembly 80.

[0058] That is, when the shift dial 20 is rotated clockwise from neutral, the D gear (after Nd) is selected. When the shift dial 20 is rotated counterclockwise, the R gear (after Nr) is selected. When the operating force is removed, the shift dial 20 returns from D or R to neutral due to the elasticity of the slot plate 40 and the stop assembly 80.

[0059] The electronic shift control device according to various exemplary embodiments of the present invention further includes a sensing gear 90 rotatably coupled to the main housing 10 and engaging with the rotating body 30 in an external gear manner; and a magnet 100 engaged with the sensing gear 90.

[0060] A gear portion 31 of predetermined length is circumferentially formed on the outer surface of the rotating body 30. The gear portion 31 of the rotating body 30 engages with the sensing gear 90 in an external gear configuration. The magnet 100 is fixed to the sensing gear 90 to face the PCB 50.

[0061] When the shift dial 20 is rotated by the driver, causing a position change, the rotating body 30 and the sensing gear 90 rotate. When the sensing gear 90 rotates, the PCB 50 identifies the shift position signal of any one of the R, N (Nd and Nr) and D gears based on the change in magnetic flux caused by the position change of the magnet 10, and outputs the shift position signal to the TCU 70.

[0062] The shift-by-wire (SBW) system, as an electronic shift system, has no mechanical connection structure such as a cable between the shift dial 20 and the vehicle's transmission. When the driver operates the shift dial 20 and selects any of the shift gears R, N (Nd and Nr), and D, the PCB 50 transmits the selected shift signal to the TCU 70. The transmission actuator 110 operates in response to the signal provided from the TCU 70, and the operation of the transmission actuator 110 applies or cuts off hydraulic pressure to the hydraulic circuit of each shift gear in the transmission 120, thereby enabling the transmission 120 to perform the shift electronically.

[0063] The electronic shift control device according to various exemplary embodiments of the present invention further includes a P-gear button 130, which is disposed in the center portion of the shift dial 20 to be movable up and down and configured to be pressed by the driver. When the P-gear button 130 is activated, the PCB 50 recognizes the contact of the P-gear button 130 and generates a P-gear signal, which is transmitted to the TCU 70.

[0064] When the driver presses the P gear button 120, the switch rubber located below the P gear button 130 is elastically compressed and comes into contact with the PCB 50. When the P gear button 130 is operated, the PCB 50 recognizes the contact of the P gear button 130 and generates a P gear signal, which is then transmitted to the TCU 70.

[0065] When the driver releases the P gear button 130, the downward-moving P gear button is restored to its initial position by the elasticity of the switch rubber.

[0066] The haptic motor assembly 60 according to various exemplary embodiments of the present invention may include a motor housing 61 fixed to a main housing 10; a haptic motor 62 inserted into and fixed within the motor housing 61, electrically connected to a PCB 50 and controlled by the PCB 50 for operation; and a roller 63 rotatably coupled to the motor housing 61 and in contact with a slot plate 40.

[0067] PCB 50 operates haptic motor 62 only when the shift signal selected when operating shift dial 20 matches the actual shift signal of transmission 120 fed back by TCU 70.

[0068] That is, when the shift signal selected when operating the shift dial 20 is transmitted to the PCB 50, the PCB 50 transmits the selected shift signal to the TCU 70. The transmission actuator 110 is controlled by the TCU 70 to operate and perform the actual shift in the transmission 120. The actual shift signal of the transmission 120 is fed back to the PCB 50 through the TCU 70. The PCB 50 only operates the haptic motor 62 when the shift signal selected when operating the shift dial 20 is consistent with the actual shift signal of the transmission 120 fed back by the TCU 70.

[0069] When the shift dial 20 is operated and reverse gear (R) is selected, the PCB 50 controls the haptic motor 62 to operate and generate a haptic signal. This haptic signal is transmitted to the shift dial 20 with minimal loss via the haptic motor housing 61, roller 63, slot plate 40, and rotating body 30, and ultimately to the driver's hand operating the shift dial 20. Therefore, the driver receives the haptic signal due to the vibration of the haptic motor 62, thereby maximizing the driver's recognition of the shift dial operation.

[0070] Since the driver receives tactile signals through the shift dial 20, accidents caused by incorrect gear selection can be prevented, thereby further improving safety during gear shifting.

[0071] According to various exemplary embodiments of the present invention, an elastic protrusion 64 protruding in one direction is integrally formed on the motor housing 61, and the motor housing 61 is in linear or point contact with the main housing 10 through the elastic protrusion 64.

[0072] When the motor housing 61 is positioned to contact the surface of the main housing 10, most of the vibrations generated by the tactile motor 62 are transmitted to the main housing 10, which is in contact with the surface of the motor housing 61, and a small amount of vibration is transmitted to the shift dial 20 held by the driver. Therefore, the driver cannot clearly identify the tactile signals (tactile feedback signals) and may select the wrong gear when shifting gears.

[0073] Therefore, according to various exemplary embodiments of the present invention, the motor housing 61 and the main housing 10 are in line contact or point contact with each other through the elastic protrusion 64 of the motor housing 61, thereby minimizing the vibration of the tactile motor 62 transmitted to the main housing 10 and increasing the intensity of the tactile signal transmitted to the shift dial 20. Thus, the driver can more clearly identify the tactile signal, thereby preventing the selection of the wrong shift gear.

[0074] Since the elastic protrusion 64 protrudes in the opposite direction to the roller 63 in various exemplary embodiments of the present invention, when the elastic protrusion 64 contacts the main housing 10, the force that moves the motor housing 61 toward the slot plate 40 is applied to the motor housing 61 by the elastic force of the elastic protrusion 64. Therefore, the contact force between the roller 63 and the slot plate 40 can be reliably maintained.

[0075] According to various exemplary embodiments of the present invention, since the rotating roller 63 is in contact with the slot plate 40, the rotating roller 63 helps the shift dial 20 to rotate smoothly, while preventing the shift dial 20 from getting stuck when it rotates.

[0076] According to various exemplary embodiments of the present invention, the housing cover 65 is connected to the bottom of the motor housing 61, the vibration isolation pad 66 is connected to the housing cover 65, and the motor housing 61 is connected to the main housing 10 through the vibration isolation pad 66.

[0077] The vibration damping pad 66 absorbs the vibration of the haptic motor 62, thereby minimizing the vibration transmitted to the main housing 10. Therefore, most of the vibration of the haptic motor 62 is transmitted to the shift paddle 20, so the driver can more clearly recognize the haptic signals.

[0078] In order to minimize the contact portion between the main housing 10 and the motor housing 61 via the vibration isolation pad 66, the housing rib 11 protrudes from the main housing 10 and the vibration isolation pad 66 is configured to contact the housing rib 11.

[0079] The haptic motor 62 is electrically connected to the PCB 50 via wiring 141 and connector 142, and the haptic motor 62 can be configured to make direct contact with the PCB 50 without wiring if needed.

[0080] Figure 1 and Figure 2 The reference numeral "150" in the diagram indicates cover 150. Cover 150 improves the appearance aesthetically by covering most of the electronic shift control unit, including the main housing 10. Shift dial 20 and P (Park) button 130 protrude to be exposed on cover 150. The symbols R, N, and D indicating shift positions are provided on cover 150.

[0081] The tactile motor 62 according to various exemplary embodiments of the present invention can be applied to and used in all electronic shift control devices, which are shift lever type, enabling the user to shift gears by operating a shift lever; button type, enabling the user to shift gears by operating a shift button; column type, wherein the shift lever is disposed on the steering column; and toggle type, enabling the user to shift gears by operating a toggle switch.

[0082] As described above, the electronic shift control device according to various exemplary embodiments of the present invention includes a shift dial 20 operated by the driver to select R, N (Nd and Nr) and D gears; a P gear button 130 operated to select P gear; and a tactile motor 62 that generates tactile signals. Therefore, when the driver shifts to a specific gear (R) of the vehicle by operating the shift dial 20, the tactile motor 62 is activated and a tactile signal (tactile sensation signal) is transmitted to the driver, thereby preventing accidental operation by the driver during gear shifting. Thus, it has the advantage of improved safety.

[0083] Furthermore, since the vibration transmitted to the tactile motor 62 of the main housing 10 can be minimized by the vibration isolation pad 66 disposed between the main housing 10 and the motor housing 61, the intensity of the tactile signal transmitted to the shift dial 20 can be increased. Therefore, it has the advantage that the driver can more clearly identify the tactile signal.

[0084] In an exemplary embodiment of the present invention, PCB 50 may include a memory and at least one processor configured to execute one or more steps interpreted as an algorithmic structure. The memory stores the algorithmic steps, and the processor executes the algorithmic steps to perform one or more processes of a method according to various exemplary embodiments of the present invention. A control device according to an exemplary embodiment of the present invention may be implemented using a non-volatile memory and a processor configured to store algorithms for controlling the operation of various components of a vehicle or data regarding software commands for executing the algorithms, and the processor configured to execute the operations described above using the data stored in the memory. The memory and processor may be separate chips. Alternatively, the memory and processor may be integrated into a single chip. The processor may be implemented as one or more processors. The processor may include various logic circuits and arithmetic circuits, capable of processing data according to a program provided by the memory, and capable of generating control signals based on the processing results.
