AI Technical Summary
In existing electronic shifting systems, haptic motors are prone to vibration and noise during operation, which can lead to component damage, and there is a lack of effective haptic feedback mechanisms to prevent misoperation.
An air gap is set around the haptic motor, and vibration and noise are absorbed by the pad component. The haptic motor only runs when the shift signal is consistent, generating a haptic signal to prevent misoperation.
The vibration and noise transmission during the operation of the haptic motor are effectively reduced. The air gap G1 between the fixed bracket 20 and the haptic motor 80 prevents the transmission of vibration and noise during the operation of the haptic motor 80, thereby improving the durability and safety of the system.

Description
TECHNICAL FIELD
[0001] The present disclosure relates to an electronic shift control apparatus, and more particularly, to an electronic shift control apparatus configured to prevent misoperation by transmitting a haptic signal to a driver when the driver shifts to a specific shift range, which can minimize unnecessary vibration and noise transmission from a haptic motor to other parts by applying an air gap around the haptic motor, and using the air gap, damage to the haptic motor when the haptic motor operates can be prevented. BACKGROUND
[0002] Generally, in a vehicle equipped with an automatic transmission, a gear of a desired shift stage is automatically operated by controlling hydraulic pressure within a shift range set for a vehicle speed.
[0003] An automatic transmission generates a gear ratio using a hydraulic circuit, a planetary gear set, and a friction member to shift, and these components are controlled by a Transmission Control Unit (TCU).
[0004] Unlike the existing mechanical shift system, a Shift-By-Wire (SBW) system, which is a vehicle electronic shift system, does not have a mechanical connection structure such as a cable between a transmission and a shift lever. In the SBW system, when a sensor value generated by operating an electronic shift control apparatus (shift lever or shift button) is transmitted to the TCU, a solenoid or a motor operates by an electronic signal from the TCU, and hydraulic pressure is selectively applied to a hydraulic circuit of each gear stage, thereby electronically controlling shifting.
[0005] Accordingly, an automatic transmission based on the SBW system has the following advantages: by simply operating an electronic shift control apparatus (shift lever, button, or dial), a driver's shift intention is transmitted to the TCU using an electric signal, shifting to a D (Drive)-range, an R (Reverse)-range, and an N-range (Nd-range or Nr-range) is easily achieved, and has the following another advantage: because the shift control apparatus can be formed in a small size, a spacious area can be secured between a driver's seat and a passenger's seat.
[0006] As a shift method using an electronic shift system, generally, there are a lever type using a lever, a button type using a button, and a dial type using a dial.
[0007] The above description provided as related art of the present disclosure is only for the purpose of helping to understand the background of the present disclosure, and should not be understood as including the related art known to those skilled in the art. SUMMARY
[0008] The present disclosure relates to an electronic shift control device having a shift dial operated by a driver to select R-gear, N-gear (Nd-gear and Nr-gear), and D-gear, and a P-gear button operated to select P (parking)-gear, and an object of the present disclosure is to provide an electronic shift control device that can prevent misoperation and improve safety by transmitting a haptic signal to the driver when the driver shifts to a specific shift gear, and in particular, that can minimize unnecessary vibration and noise transmission from a haptic motor to other parts by applying an air gap around the haptic motor, and using the air gap, damage to the haptic motor when the haptic motor is operated can be prevented.
[0009] To achieve the object of the present disclosure, an electronic shift control device includes a fixing bracket fixed to a main housing, a rotator installed to be rotatable with respect to the main housing, a shift dial coupled to the rotator, the shift dial being configured to be rotated by the driver with the rotator to select any shift gear of a vehicle when rotated, a main printed circuit board (PCB) fixed to the main housing and outputting a shift gear signal of any one of R-gear, N-gear, or D-gear selected by the shift dial to a transmission control unit (TCU), and a haptic motor fixed to the fixing bracket, the haptic motor being operated under control of the main PCB to generate a haptic signal when operated.
[0010] The shift gear of the vehicle selected when the shift dial is operated can be any one of R-gear, N-gear, or D-gear.
[0011] The electronic shift control device can further include a sensing gear rotatably coupled to the main housing and engaged with the rotator of the external gear type, and a magnet combined with the sensing gear, wherein the main PCB can output the shift gear signal of any one of R-gear, N-gear, or D-gear based on a change in magnetic flux caused by a change in position of the magnet when the shift dial is rotated.
[0012] The haptic motor can be inserted and installed in a mounting groove formed at the fixing bracket, a bottom of the haptic motor can be coupled to a bottom of the mounting groove by an adhesive member, and a front surface, a rear surface, a left surface, and a right surface of the haptic motor can be spaced apart from the mounting groove such that an air gap exists between the haptic motor and the mounting groove.
[0013] The mounting groove can be upwardly open, and a mouth of the mounting groove can have an inclined surface such that a cross-sectional area thereof gradually increases upward.
[0014] The electronic shift control device can further include a pad member coupled to a top of the haptic motor and absorbing vibration and noise generated when the haptic motor operates.
[0015] The electronic shift control device can further include a pad member coupled to a top and a bottom of the haptic motor and absorbing vibration and noise generated when the haptic motor operates.
[0016] The electronic shift control device can further include a support PCB coupled to hook protrusions protruding more upward than the fixing bracket, fixing a position of the haptic motor in an up-down direction by pressing a top of the pad member and connected to the main PCB through a wire, and a P-range button disposed to be movable up and down at a center of the shift dial and configured to be pressed by a driver, wherein the support PCB can generate and deliver a P-range signal to the main PCB when contact with the P-range button occurs.
[0017] Vibration and noise generated when the haptic motor operates can be absorbed by the pad member and not delivered to the support PCB.
[0018] The main PCB can operate the haptic motor only when a shift signal selected while operating the shift dial or the P-range button and an actual shift signal of the transmission fed back through the TCU are consistent with each other.
[0019] The haptic motor can operate and generate a haptic signal under control of the main PCB when the shift dial is operated and R-range is selected.

[0024] The rotator can be rotated by a bearing provided between the main housing and the rotator or between the fixing bracket and the rotator.
[0025] The electronic shift control device according to the present disclosure includes a shift dial operated by a driver to select R-gear, N-gear (Nd-gear and Nr-gear), and D-gear, and a P-gear button operated to select P-gear. Accordingly, when the driver shifts to a specific shift gear (R-gear or P-gear) by operating the shift dial or the P-gear button, the haptic motor operates, and a haptic signal (tactile signal) is configured to be delivered to the driver, so that the driver can be prevented from misoperation while shifting. Accordingly, an effect that safety is improved is obtained.
[0026] Further, since an air gap is formed around the haptic motor that generates a haptic signal in the present disclosure, unnecessary transmission of vibration and noise generated by the haptic motor to other parts is minimized, so that durability of the parts can be improved.
[0027] Further, since the fixing bracket and the haptic motor can be spaced apart from each other by the air gap in the present disclosure, an effect that damage of the haptic motor by the fixing bracket when the haptic motor operates is prevented is obtained. BRIEF DESCRIPTION OF DRAWINGS

[0048] The electronic shift control device according to an exemplary embodiment of the present disclosure will now be described in detail with reference to the accompanying drawings.
[0049] like Figures 1 to 9 As shown, the electronic shift control device according to this disclosure includes: a main housing fixed inside the vehicle; a mounting bracket 20 fixed to the main housing 10; a rotator 40 mounted to be rotatable relative to the main housing 10; a shift dial 50 coupled to the rotator 40, the shift dial 50 being configured to be rotated by the driver using the rotator 40 to select any shift gear of the vehicle during rotation; a main printed circuit board (PBC) 70 fixed to the main housing 10 and outputting a shift gear signal selected by the shift dial 50 to a transmission control unit (TCU) 60; and a tactile motor 80 fixed to the mounting bracket 20, the tactile motor 80 operating under the control of the main PCB 70 to generate tactile signals during operation.
[0050] The main housing 10 can be fixed to the vehicle body, such as the console near the driver's seat, the center fascia, etc., but the mounting location can be changed if needed.
[0051] The mounting bracket 20 can be fixed to the main housing 10 by means of connecting members 90 such as bolts or screws.
[0052] The bearing 30 is disposed between the main housing 10 and the rotator 40, so the rotator 40 can rotate relative to the main housing 10 via the bearing 30.
[0053] As another example, the bearing 30 is provided between the rotator 40 and the fixed bracket 20 fixed to the main housing 10 through the coupling member 90, and thus the rotator 40 can be rotated with respect to the main housing 10 and the fixed bracket 20 through the bearing 30.
[0054] The bearing 30 includes an inner ring coupled to the main housing 10 or the fixed bracket 20, an outer ring coupled to the rotator 40, and a plurality of balls provided between the inner ring and the outer ring. Thus, the rotator 40 can be rotated clockwise or counterclockwise with respect to the main housing 10 and the fixed bracket 20 through the bearing 30.
[0055] The rotator 40 is integrally coupled to the bottom of the shift knob 50 and extends downward from the shift knob 50. When the driver operates the shift knob 50, the shift knob 20 and the rotator 40 are rotated clockwise or counterclockwise together with respect to the main housing 10 and the fixed bracket 20.
[0056] The main PCB 70 is provided below the rotator 40, is fixed to the main housing 10, and is electrically connected to a power source (a battery) of the vehicle to be able to obtain power supply.
[0057] The main PCB 70 has a function of outputting a shift range signal selected when the shift knob 50 is operated to the TCU 70, and a function of controlling the operation of the haptic motor 80. The frequency, intensity, and number of vibrations generated by the haptic motor 80 can be changed under the control of the main PCB 70.
[0058] The shift range of the vehicle selected when the shift knob 50 is operated is one of an R-range, an N-range (an Nd-range and an Nr-range), or a D-range.
[0059] The rotator 40 has a groove protruding outward, the groove contacts a detent assembly having elasticity, and the detent assembly is fixed to the main housing 10.
[0060] When the shift knob 50 is rotated, the contact between the groove and the detent assembly generates an operation feeling. When the driver releases the rotated shift knob 50, the rotated shift knob 50 returns to an initial position by the elasticity of the detent assembly.
[0061] That is, when the shift dial 50 is rotated one stage clockwise from the Null-range, the Nd-range is selected, and when the shift dial 50 is further rotated one stage clockwise from the Nd-range, the D-range is selected. Also, when the shift dial 50 is rotated one stage counterclockwise from the Null-range, the Nr-range is selected, and when the shift dial 50 is further rotated one stage counterclockwise from the Nr-range, the R-range is selected. When the operation force is removed after operating the shift dial 50, the shift dial 50 returns to the Null-range from the D-range or the R-range by the elasticity of the pawl assembly in contact with the groove.
[0062] The electronic shift control device according to the present disclosure further includes a sensing gear 100 rotatably coupled to the main housing 10 and engaged with the external gear type rotator 40, and a magnet 110 combined with the sensing gear 100.
[0063] A gear part 41 having a predetermined length is formed circumferentially on the outer surface of the rotator 40. The gear part 41 of the rotator 40 is engaged with the external gear type sensing gear 100. The magnet 110 is fixed to the sensing gear 100, facing the main PCB 70.
[0064] When the driver rotates the shift dial 50, then the rotator 40 and the sensing gear 100 rotate. When the sensing gear 100 rotates, the main PCB 70 recognizes the shift range signal of any one of the R-range, the N-range (the Nd-range and the Nr-range), or the D-range based on the change in magnetic flux caused by the change in position of the magnet 110, and outputs the shift range signal to the TCU 60.
[0065] The shift-by-wire (SBW) system, which is an electronic shift system, does not have a mechanical connection structure such as a cable between the shift dial 50 and the transmission of the vehicle. When the driver operates the shift dial 50 and selects any one of the shift ranges of the R-range, the N-range (the Nd-range and the Nr-range), and the D-range, the main PCB 70 transmits the selected shift signal to the TCU 60, the transmission actuator 120 is operated in response to the signal given from the TCU 60, and by the operation of the transmission actuator 120, hydraulic pressure is applied or cut off to the hydraulic circuit of each shift range of the transmission 130, so that the transmission 130 electronically performs the shift.
[0066] A mounting groove 21 having a predetermined size is formed at the fixing bracket 20, and the haptic motor 80 is inserted and mounted in the mounting groove 21 of the fixing bracket 20.
[0067] An adhesive member 140 such as a double-sided tape is coupled to the bottom of the haptic motor 80 to fix the haptic motor 80, so the haptic motor 80 is fixed to the bottom of the mounting groove 21 by the adhesive member 140.
[0068] When the haptic motor 80 is inserted and installed in the installation groove 21 of the fixing bracket 20, the front surface, the rear surface, the left surface, and the right surface of the haptic motor 80 are spaced apart from the installation groove 21, such that an air gap G1 is formed between the haptic motor 80 and the installation groove 21.
[0069] The air gap G1 is a space existing between the haptic motor 80 and the installation groove 21, which prevents or minimizes the vibration and noise generated by the haptic motor 80 from being unnecessarily transmitted to surrounding parts.
[0070] The installation groove 21 formed at the fixing bracket 20 is upwardly open, and the mouth portion (a cross section of the installation groove from the middle portion to the top portion in the up-and-down direction) of the installation groove 21 is formed such that the cross-sectional area thereof is gradually increased upward, so that the haptic motor 80 can be easily inserted into the installation groove 21. To this end, the mouth portion of the installation groove 21 can have an inclined surface 22.
[0071] A pad member 150 made of rubber is fixed to the top portion of the haptic motor 80 inserted and installed in the installation groove 21, and a support PCB 160 is fixed above the pad member 150.
[0072] The pad member 150 is coupled to the top portion of the haptic motor 80 by an adhesive member, and the upper portion of the pad member 150 is partially exposed outside the installation groove 21 when the haptic motor 80 is inserted and installed in the installation groove 21.
[0073] A plurality of hook-shaped protrusions 170 protruding more upward than the fixing bracket 20 are formed around the installation groove 21, and the support PCB 160 is held and fixed by the hook-shaped protrusions 170. When the support PCB 160 is held and fixed by the hook-shaped protrusions 170, the bottom portion of the support PCB 160 presses the top portion of the pad member 150.
[0074] When the support PCB 160 is held and fixed by the hook-shaped protrusions 170, the rotation of the support PCB 160 is prevented by the hook-shaped protrusions 170. Also, since the support PCB 160 presses the top portion of the pad member 150, the position of the haptic motor 80 can be fixed in the up-and-down direction.
[0075] The vibration and noise generated when the haptic motor 80 operates are mostly absorbed by the pad member 150, and thus they are not or minimally transmitted to the support PCB 160. Accordingly, it is possible to prevent damage to the support PCB 160 caused by the vibration of the haptic motor 80.
[0076] The support PCB 160 is disposed above the main PCB 70, and the main PCB 70 and the support PCB 160 are connected to each other by a wire 180, so as to be supplied with power and transmit / receive signals.
[0077] The LED 190 responsible for lighting is electrically connected to the support PCB 160, so the LED is turned on and off under the control of the support PCB 160.
[0078] As another example of the present disclosure, the pad member 150 can be coupled to the top and bottom of the haptic motor 80, whereby the effect of reducing the vibration and noise generated by the haptic motor 80 can be further improved.
[0079] The electronic shift control device according to the present disclosure further includes a P-range button 200 disposed to be moved up and down at the center of the shift dial 50 and configured to be pressed by the driver. Upon occurrence of contact with the P-range button 200, the support PCB 160 generates and transmits a P-range signal to the main PCB 70 through the wiring 180.
[0080] When the driver presses the P-range button 200, the switch rubber 210 disposed below the P-range button 200 is elastically compressed to come into contact with the support PCB 160, the support PCB 160 recognizes a P-range signal generated when the P-range button 200 is operated, and transmits the P-range signal to the main PCB 70 through the wiring 180. When the driver releases the P-range button 200, the P-range button 200 moved downward returns upward to the initial position by the restoring force of the switch rubber 210.
[0081] The main PCB 70 operates the haptic motor 80 only when the shift signal selected when the shift dial 50 or the P-range button 200 is operated coincides with the actual shift signal of the transmission 130 fed back through the TCU 60.
[0082] That is, when the shift signal selected when the shift dial 50 or the P-range button 200 is operated is transmitted to the main PCB 70, the main PCB 70 transmits the selected shift signal to the TCU 60, the transmission actuator 110 is controlled to be operated by the TCU 60, and the actual shift is performed in the transmission 130, the actual shift signal of the transmission 130 is fed back to the main PCB 70 through the TCU 60, and the main PCB 70 operates the haptic motor 80 only when the shift signal selected when the shift dial 50 or the P-range button 200 is operated coincides with the actual shift signal of the transmission 130 fed back through the TCU 60.
[0083] When the shift dial 50 is operated and the R-gear is selected, the haptic motor 80 operates and generates a haptic signal under the control of the main PCB 70. The haptic signal is transmitted to the shift dial 50 through the fixed bracket 20, the bearing 30, and the rotator 40 with the least loss and is finally transmitted to the hand of the driver who operates the shift dial 50. Accordingly, the driver receives the haptic signal due to the vibration of the haptic motor 80, so that the recognition of the driver who operates the shift dial can be maximized.
[0084] Since the driver receives the haptic signal through the shift dial 50, accidents caused by the erroneous selection of the shift gear can be prevented, so that the safety at the time of shifting can be further improved.
[0085] When the P-gear button 200 is operated and the P-gear is selected, the haptic motor 80 can operate and generate a haptic signal under the control of the main PCB 70. The haptic signal generated in this case is transmitted to the P-gear button 200 through the fixed bracket 20, the dial guide 220, the dial bezel 230, the dial glass 240, and the dial gasket 250 and is finally transmitted to the hand of the driver who operates the P-gear button 200. Accordingly, the driver can receive the haptic signal due to the vibration of the haptic motor 80.
[0086] The support PCB 160 is coupled to the fixed bracket 20, the dial guide 220 is coupled to the fixed bracket 20 to cover the support PCB 160, the dial bezel 230, the dial glass 240, and the dial gasket 250 are combined to cover the dial guide 220, and the P-gear button 200 is disposed at the center of the dial gasket 250.
[0087] The light generated by the LED 190 is exposed to the outside through the dial glass 240, so that the aesthetic appearance of the electronic shift control device can be further improved in terms of aesthetics.
[0088] The configuration in which the haptic motor 80 operates and generates a haptic signal when the P-gear button 200 is operated is an optional manner, and the haptic motor 80 can not operate and can not generate a haptic signal when the P-gear button 200 is operated.
[0089] The haptic motor 80 according to the present disclosure can be applied to and used for other shift control devices of a lever type in which shifting is performed by operating a shift lever, a button type in which shifting is performed by operating a shift button, a column type in which a shift lever is disposed on a steering column, and a dial type in which shifting is performed by operating a dial switch.
[0090] As described above, the electronic shift control device according to the present disclosure includes a shift dial 50 that is operated by a driver to select an R-gear, an N-gear (an Nd-gear and an Nr-gear), and a D-gear, a P-gear button 200 that is operated to select a P-gear, and a haptic motor 80 that generates a haptic signal. Thus, when the driver shifts the vehicle to a specific gear (R-gear or P-gear) by operating the shift dial 50 or the P-gear button, the haptic motor 80 is operated, and a haptic signal (tactile signal) can be transmitted to the driver, so that the driver can be prevented from misoperation at the time of shifting. Thus, it has an advantage in that safety is improved.
[0091] Further, since the air gap G1 is formed around the haptic motor 80 that generates the haptic signal in the present disclosure, it is possible to minimize unnecessary transmission of vibration and noise generated by the haptic motor 80 to other parts, so that the durability of the parts can be improved.
[0092] Further, since the fixing bracket 20 and the haptic motor 80 can be spaced apart from each other by the air gap G1 in the present disclosure, it is possible to prevent damage to the haptic motor 80 by the fixing bracket 20 when the haptic motor 80 is operated.
[0093] If there is no air gap between the fixing bracket 20 and the haptic motor 80, the fixing bracket 20 can be violently vibrated when the haptic motor 80 is operated, and any vibration of the fixing bracket 20 is transmitted back to the haptic motor 80, so that the haptic motor 80 can be damaged. Thus, according to the present disclosure, by the air gap G1 between the fixing bracket 20 and the haptic motor 80, it is possible to prevent damage to the haptic motor 80 by the fixing bracket 20 when the haptic motor 80 is operated.
[0094] Although the present disclosure is described with reference to specific embodiments shown in the drawings, it will be apparent to those skilled in the art that the present disclosure can be varied and modified in various ways without departing from the scope of the present disclosure described in the appended claims.
