Accordingly, the rotary switch movable block 3250 has a lower surface of the rotary switch movable block 3250 and the rotary switch housing body 3220 by an elastic force applied by the rotary switch movable block detent elastic part of the rotary switch movable block detent part. The rotary switch stopper 3291 is disposed to abut and at the same time accommodated in the rotary switch stopper counterpart 3293 to prevent rotation of the rotary switch movable block, and ultimately the rotary knob.

On the other hand, when an external force by the user is applied to the rotary knob, the rotary switch movable block is moved toward the rotary switch housing cover side, thereby disengaging the engagement between the rotary switch stopper 3291 and the rotary switch stopper counterpart 3293, and allowing the user to rotate the rotary knob ( 3100) can be rotated. Through such a structure, it is possible to prevent an unwanted rotary knob rotation operation by the user.

The rotary switch stopper 3291 is engaged with the rotary switch stopper counterpart 3293 by the elastic force exerted therein, thereby preventing unwanted rotation of the rotary knob. Although shown here to provide the rotary switch movable block detent elastic part with the axial elastic force applied to the rotary knob, it is apparent from the above that the configuration may further be provided with a separate elastic member.

Then, when the user wants to rotate the rotary knob, as shown in FIGS. 18 and 19, the rotary knob 3100 acts in a direction away from the rotary switch 3200, whereby the rotary The rotary switch movable block 3250 connected to the knob 3100 is moved toward the rotary knob 3100, thereby releasing the engagement structure between the rotary switch stopper 3291 and the rotary switch stopper counterpart 3253. Therefore, at the same time, the user can rotate the rotary knob 3100 to the rotary knob 3100, and the rotary switch sensing counterpart and the rotary switch disposed on the rotary switch movable block 3250 connected to the rotary knob 3100. By changing the electrical signal is generated through the rotary switch detection sensor disposed on the substrate it is possible to perform a predetermined shift range switching function. In this process, the rotary switch movable block holder may be operated to maintain a constant distance between the rotary switch detection counterpart and the rotary switch detection sensor, thereby preventing occurrence of a measurement error due to a change in a predetermined detection function. In addition, at this time, the user may provide a sense of theft by performing a predetermined detent function through the rotary switch movable block detent unit. Then, when the in-output of the rotary knob 3100 applied by the user is removed, the rotary knob 3100 moves downward by the elastic restoring force of the rotary knob switch movable block detent elastic part 3263 and the rotary switch stopper. The engagement between the rotary switch stopper counterparts may be achieved again.

In addition, in some cases, the control unit 30 may be in electrical communication with the storage unit 50 and may perform a storage function for buffering a signal sensed by each sensing unit and transmitted to the control unit 30. Various variations are possible.

On the other hand, as an example of the rotary switch 3200 of the present invention is provided with a Wheatstone bridge sensor circuit and using the output from the shift range change due to the operation of the rotary knob that is not clear by the user due to the prevention of malfunction or sudden shift It is also possible to prevent vehicle transmission damage from occurring.

The rotary substrate 3300 includes a rotary switch detection sensor 3283 at a position corresponding to the rotary switch detection counterpart 3231 on one surface of the rotary switch 3200 toward the rotary switch movable block part 3240. As shown in Fig. 26, the rotary switch detecting sensor 3283 includes two adjacent Wheatstone bridge sensor circuits 3283a and 3283b, each of which is composed of a plurality of Hall elements. Taking the same circuit configuration with 315, the orientations of the two Wheatstone bridge sensor circuits 3283a and 3283b are arranged to have a 45 ° orientation angle difference with respect to each other. Here, Vcc1 and Vcc2 represent supply voltages applied to respective Wheatstone bridge sensor circuits, GND1 and GND2 represent ground voltages for respective circuits, and +/- Vo1 and Vo2 represent respective Wheatstone bridge sensor circuits. Positive / negative output voltage.

The intersection angle between the diagonal lines is 45 °. Accordingly, when the rotary switch detection counterpart 3231 disposed in the rotary switch movable block 3240 of the rotary switch 3200 disposed facing the whistle bridge sensor circuits 3283a and 3283b performs a rotary motion, FIG. Two sensor measurement signals (X, Y) are detected by the positive / negative output voltage of 26.

Figure 112009079847008-pat00004

Figure 112009079847008-pat00005

Here, when the influence on the temperature T is significantly smaller than the influence on the angle θ, the relationship can be expressed as follows.

Figure 112009079847008-pat00006

Figure 112009079847008-pat00007

When the rotation angle θ of the rotary switch sensing counterpart 3331 is calculated from the relations, it may be expressed as the following relationship.

Figure 112009079847008-pat00008

Accordingly, the rotation angle θ of the rotary switch detection counterpart 3231, and ultimately, the rotary knob 3100, may be calculated through the two signals of the measured rotary switch detection sensor 3283.

When the driver rotates the rotary knob 3100 of the rotary unit included in the vehicle shift range switching device of the present invention, the shift control process by the signal from the rotary switch detection sensor 3283 may be configured as follows.

First, the rotation angle, and ultimately the shift range, selected by the rotation of the rotary knob 3100 by the driver is sensed by the rotary switch detector 3280 and determined by the controller 30. The shift range according to the embodiment of the present invention includes DM, D, N, R, and RM, D represents a forward traveling shift range, N represents a neutral shift range, R represents a reverse shift range, and D and R The shift range disposed on the side of the speed range represents a low speed forward traveling speed range and a low speed reverse speed range, and the selection of the speed range is just an example of the present invention, but the configuration of the speed change range of the present invention is not limited thereto. However, in the shift range determination according to an embodiment of the present invention, gray zone shift ranges (gray DM, gray DM-D, gray DN, gray) are located between and side portions of shift ranges such as DM, D, N, R, and RM. NR, gray R-RM, and gray RM) are disposed, and the gray zone shift range is a buffer area to prevent damage due to a sudden load change in the vehicle transmission due to a sudden shift range change. That is, the shift range corresponding to the rotation angle of the rotary knob 3100 adjusted by the user does not directly indicate the DM, D, N, R, or RM corresponding to the shift range of the actual vehicle, and the respective DM, D, N , When it is disposed between R and RM, the current shift range is determined from the shift range and the shift range table preset in the storage unit 50 before the signal for the rotation angle of the rotary knob for selecting a new shift range is input. By calculating and transferring the vehicle to the vehicle transmission to form a predetermined shift state, it is possible to prevent a problem of deterioration in riding comfort due to load weighting or shift shock due to a sudden shift range change.

First, as illustrated in FIG. 31, a signal output step in which the rotary switch detection sensor 310 detects a signal and outputs a signal to the signal processor 20 is performed (S210). That is, two voltages as a sensor measurement signal for detecting a signal caused by the magnetic field of the rotary switch detection counter 3328 and the two Wheatstone bridge sensor circuits 3283a and 3283b of the rotary switch detection sensor 310 have a constant phase difference. The signal is output to the signal processor 20 through the connector 320.

Thereafter, the signal processor 20 amplifies the two sensor measurement signals input through the amplifier x and digitizes them using an AD converter to allow processing by the controller or the like (S220). That is, if the maximum potential level of the sensor measurement signal is about several hundred microseconds, it is amplified to several V through an amplifier, and the amplified several V sensor measurement signal has an amplification potential level maximum / 256 resolution through an 8-bit A / D converter. Is converted into a digital signal.

Thereafter, the rotary switch sensing counterpart calculation rotation angle θc is calculated through the signal processed two sensor measurement signals (S230). The calculating step may include a conversion step and an angle calculation step. That is, if the two sensor signals processed by the signal can be converted into the measured voltage values by multiplying the corresponding resolutions, and the converted measured voltage values are X and Y, respectively, the operation rotation angle θc of the rotary switch sensing counterpart is It is calculated through the following relationship.

Figure 112009079847008-pat00009

Thereafter, a calculation step of calculating the rotary switch sensing counterpart actual rotation angle θa is performed by comparing the rotary switch sensing counterpart operational rotation angle θc with the rotary switch sensing counterpart zero angle θz (S240). . That is, the calculating step includes an angle comparison step and an angle setting step. In the angle comparison step, the controller 30 stores the rotary switch sensing counterpart zero z and the rotary switch sensing counterpart calculated by the calculator 40 in advance. Compare When the rotary switch sensing counterpart operating rotation angle θc is equal to or greater than the rotary switch sensing counterpart zero angle θz, the control unit 30 uses the calculation unit 40 according to the following equation and the actual rotary angle of the rotary switch sensing counterpart ( An angle setting step of calculating and calculating θa) is performed.

Figure 112009079847008-pat00010

In addition, when the rotary switch sensing counterpart calculation rotation angle θc is smaller than the rotary switch sensing counterpart zero angle θz, the control unit 30 uses the calculation unit 40 according to the following relational expression to actually operate the rotary switch sensing counterpart. An angle setting step of calculating and calculating the rotation angle θa is performed.

Figure 112009079847008-pat00011

Then, the set rotary switch sensing counterpart actual rotation angle θa is transmitted to the controller 30, and the controller 30 rotates the rotary switch sensing counterpart actual rotation angle θa and the preset rotation stored in the storage unit 50. A range step of determining, calculating and outputting a shift range from the angle table is performed (S250). As shown in FIG. 32, the shift range determination output step S250 includes a current input shift range calculation step S251, a shift range determination step S253, and a shift range output step S254. In the current input shift range calculation step S251, the control unit 30 receives the actual rotation angle θa and the signals of the rotation angle table from the operation unit 40 and the storage unit 40, respectively, and compares them. By comparing the actual rotation angle θa of the rotary switch detection counterpart with the rotation angle table value to calculate which of the shift ranges set in the rotation angle table is obtained by the shift operation selected by the driver. do. The shift range set in the rotation angle table includes the above-described DM, D, N, R, and RM in this embodiment, and the gray zone shift range is disposed between and the sides of each shift range. 28 and 29 are views of the range of the shift range corresponding to the actual rotation angle of the rotary knob to the rotary switch sensing counterpart of the present invention, the angle range of each shift range may vary according to design specifications. The shift ranges as buffer regions of the gray zone DM, the gray zone DM-D, the gray zone D-N, the gray zone N-R, the gray zone R-RM, and the gray RM are arranged between and on the sides of the DM, D, N, R, and RM. A predetermined current input shift range is calculated from the rotation angle table and the actual rotation angle of the rotary switch sensing counterpart. In this case, the gray zone shift range is a buffer area that determines what is the currently selected shift range in consideration of the shift range of the previous stage, taking into account the current state when it is not clear what the current shift range is from the signal output. It means an area in which a shift range disposed on both sides and sides of the gray zone shift range can be selected. For example, in the case of the gray zone D-N shift range, the shift range may be output as the D shift range or N shift range depending on the driving condition.

Then, the controller 30 executes a shift range determination step of determining which shift range is currently selected in step S253. The storage unit 50 is provided with a shift range table which is preset and stored, and the controller 30 determines the shift range selected by the user using the shift range table and the current input shift range. 34 is a shift range table according to an embodiment of the present invention. In the shift range table, a plurality of shift ranges corresponding to rotation of the rotary knob 310 and respective gray zone shift ranges disposed between the shift ranges are set, and the current shift range and the newly input current shift range are set. The comparison consists of a chart for a given new shift range, where 1 is the full-speed shift range, 3 is the DM shift range, 4 is the D shift range, 5 is the N shift range, 6 is the R shift range and 7 The RM shift range is shown, and the gray zone shift range in the previous stage represents the shift range actually output in the previous stage in the corresponding gray zone shift range. That is, in the gray level DN shift range of the previous stage, D denotes a case in which the previous stage shift range is actually output according to driving conditions and conditions, and N denotes a case in which the previous stage shift range is actually output and set according to the driving conditions and conditions. The case is shown.

35 shows a detailed configuration of the shift range determination step S235. The shift range determination step S235 includes an adjacent identical determination step S2531, and the control unit 30 includes a current input shift range and a previous step obtained by rotating the rotary knob or the rotary switch detection counterpart in the adjacent identical determination step S2531. It is determined whether or not it is the same by comparing adjacent shift ranges which are shift ranges adjacent to the shift range. The previous shift range is a shift range maintained before the current input shift range is input. The shift range is set and stored in the storage unit 50. For example, the shift range selected by the user in the previous step is present in the gray zone DN shift range. When the output shift range was N, the adjacent shift ranges that can be actually output to the vehicle transmission range are D and R shift ranges, and the controller 30 compares and determines whether the current input shift range and the adjacent shift range are the same.

When it is determined in step S2531 that the current input shift range and the previous step shift range are the same, the control unit 30 executes the shift range update step S2537. In the shift range update step S2537, the current shift range is the current input shift range. Is updated to the adjacent shift range. For example, if the shift range selected by the user in the previous step was in the gray zone DN shift range but the output shift range was N, the adjacent shift ranges that can be actually output to the vehicle transmission are D and R shift ranges. When the selected current input shift range is the D shift range, the current shift range is updated to the adjacent shift range D.

On the other hand, if it is determined in step S2531 that the current input shift range and the previous step shift range are not the same, the controller 30 executes the adjacent gray zone equal determination step S2533. The controller 30 compares the current input shift range obtained by the rotation of the rotary knob to the rotary switch detection counterpart and the adjacent gray zone shift range adjacent to the previous shift range in the same determination step (S2533) to determine whether the same is the same. . Here, the adjacent gray zone shift range indicates a shift range disposed between the adjacent actual outputable adjacent shift range and the previous shift range of the previous shift range. For example, if the shift range selected by the user in the previous step is in the gray zone DN shift range but the output shift range is N, the adjacent shift ranges are D and R shift ranges, and the gray zone DN shift range between them. And the gray zone NR shift range, where the gray zone DN shift range and the gray zone NR shift range are adjacent gray zone shift ranges. The controller 30 compares and determines whether the current input shift range and the adjacent gray zone shift range are the same.

If it is determined in step S2533 that the current input shift range and the adjacent gray zone shift range are the same, the control unit 30 executes the shift range maintenance step S2539. In the shift range maintenance step S2597, the current shift range is shifted to the previous step. The range is still maintained. For example, if the shift range selected by the user in the previous step was in the gray zone DN shift range but the output shift range was N, the adjacent shift ranges that can be actually output to the vehicle transmission are D and R shift ranges. If the selected current input range is the DN shift range between the D and N shift ranges, the previous shift range N is maintained as the current shift range.

On the other hand, when it is determined in step S2533 that the current input shift range and the adjacent gray zone shift range are not the same, the controller 30 executes the spaced gray zone equal determination step S2535. The control unit 30 compares the current input shift range obtained by the rotation of the rotary knob to the rotary switch detection counterpart in the same grayscale determination step (S2535) and the spaced gray zone shift range adjacent to the adjacent shift range adjacent to the previous shift range. Determine whether it is the same. FIG. 33 is a schematic diagram for explaining a spaced gray zone shift range. A shift range that is directly adjacent to the previous shift range and actually output to a vehicle transmission is called an adjacent shift range, and an adjacent shift range and a shearing crab. When the area disposed between the shift ranges is called the adjacent gray zone shift range, the adjacent shift range is disposed between the spaced gray zone shift range and the adjacent gray zone shift range.

For example, if the shift range selected by the user in the previous step was in the gray zone DN shift range but the output shift range was N, the adjacent shift ranges are D and R shift ranges, and adjacent grays disposed between them. The zone shift ranges are the Grayzone DN shift range and the Grayzone NR shift range, with the Grayzone DN shift range and the Grayzone NR shift range being spaced apart between the D and R shift ranges. -D shift range and Grayzone R-RM shift range (see FIG. 29). The controller 30 compares and determines whether the current input shift range and the adjacent gray zone shift range are the same.

If it is determined in step S2535 that the current input shift range and the spaced apart gray zone shift range are the same, the controller 30 executes the shift range update step S2538. In the shift range update step S2538, the current shift range is the adjacent shift. The range is updated. For example, if the shift range selected by the user in the previous step was in the gray zone DN shift range but the output shift range was N, the adjacent shift ranges that can be actually output to the vehicle transmission are D and R shift ranges, and are separated from each other. The zone shift range is a gray zone DM-D shift range and a gray zone R-RM shift range. When the current input shift range selected by the user is a gray zone DM-D shift range, which is a separate gray zone shift range, the current input shift range Is set to the D shift range, which is an adjacent shift range that is disposed between the gray-zone DM-D shift range, which is the spaced gray zone shift range, and the N shift range, which is the actually output previous stage shift range.

On the other hand, when it is determined in step S2535 that the current input shift range and the spaced apart gray zone shift range are not the same, the control unit 30 executes the shift range maintenance step S2539, and in the shift range maintenance step S2597. The range is maintained even though the previous shift range is maintained. For example, if the shift range selected by the user in the previous step was in the gray zone DN shift range but the output shift range was N, the adjacent shift ranges that can be actually output to the vehicle transmission are D and R shift ranges, and are separated from each other. The zone shift range is a gray zone DM-D shift range and a gray zone R-RM shift range. When the current input shift range selected by the user is a DM, gray zone DM, RM, or gray zone RM shift range, the current input shift range Is set to the N shift range, which is the actual previous shift range, to prevent a sudden shift range change.

Meanwhile, the method for controlling a shift range switch device for a vehicle according to the present invention may include an initialization step in which a rotary switch detection counterpart zero point (θz), which is preset and stored in the storage unit 50, is initialized and reset as shown in FIG. 30. It may be further provided before step S210. The rotary switch detection counterpart of the rotary switch of the vehicle shift range switching device 10 has a zero point angle other than zero. That is, the controller 30 resets the zero angle angle θc of the rotary switch detection counterpart stored in the storage unit 50 (S110). Then, when the rotary knob 3100 is rotated and positioned at a reference range, for example, P range, the rotary switch detecting sensor detects a magnetic field by the rotary switch detecting counterpart and outputs a voltage signal to the signal processor 20. The signal output unit 20 amplifies and converts two sensor unit zero measurement signals as voltage signals to process the signal (S120).

Thereafter, the sensor-processed zero measurement signal, which has been processed, is transmitted to the controller 30, and the controller 30 outputs the signal to the calculator 40. The calculation unit 40 calculates the rotary zero point detection counterpart calculation zero angle θzc from the input sensor unit zero measurement signal, and the calculation method is the same as described in the above-described embodiment (S130).

Then, these rotary switch sensing counterpart calculation zero angles θzc are transmitted to the control unit 30, and the control unit 30 uses the calculated rotary switch sensing counterpart calculation zero angles θzc as a new reference point. Calculation and setting to the negative zero angle (θza = θz) (S140), may be stored in the storage unit (50) (S150), various modifications are possible depending on the design specifications.

This control method prevents a sudden shift range change when the rotary knob is rotated, and if a subtle shift operation occurs in the middle of the shift range actually output to the vehicle transmission, it prevents frequent shifts through the shift range of the previous stage. It can also provide a good ride comfort.
