(Embodiment of the present invention)
The speed change operation device 1 according to the present embodiment includes a rotary knob type selector 2 shown in FIGS. 1 to 16, a first detection means 3, a shift range changeover switch 6 and a second switch as shown in FIGS. 17 and 18. The detection means 7 is provided. In addition to the above configuration, the transmission operating device 1 includes an actuator 4 and a control unit 5 as optional members.

  As shown in FIG. 1, the rotary knob type selector 2 has a desired shift range (for example, D (drive) range) and remote operation (for example, engine start / stop) instead of a conventional shift lever or shift column lever. It is a member used for selecting. The rotary knob type selector 2 is exposed from a cover 10 that covers other members, and is operated in a right or left rotation operation or a depression operation around a rotation shaft 8 that passes through the center in plan view. Allows selection.

  In the present embodiment, as shown in FIG. 1, for example, the rotary knob type selector 2 is set so that the neutral position (non-rotation position) of the rotary knob type selector 2 becomes the home position HP. Further, the state in which the rotation operation by the rotary knob type selector 2 is not performed is the selection of the N (neutral) range, the right rotation operation is the selection of the D (drive) range, the left rotation operation is the selection of the R (reverse) range, The pressing operation is set to select a P (parking) range.

  There are many shift range patterns, and all patterns can be adopted as long as they can be the shift range pattern of the rotary knob type selector 2. The shift range changeover switch 6 switches the shift range / pattern.

  The shift range changeover switch 6 is a member used for changing a shift range pattern that can be selected by the rotary knob type selector 2. The switching signal output from the shift range switch 6 is transmitted to the control unit 5 and an AT transmission (not shown). As a result, the shift operation is correctly performed.

  In the present embodiment, there are 18 shift range patterns that can be switched by the shift range changeover switch as shown in Table 1 as an example.

  In the first line of Table 1, “Pattern” indicates a shift range pattern. Further, “left rotation operation”, “right rotation operation”, and “pressing operation” indicate each operation of the rotary knob type selector, and “corresponding drawing” indicates a diagram number indicating each pattern.

  Further, in the second column “left rotation operation” and the third column “right rotation operation” in Table 1, “N → R” and “N → D” indicate the left rotation operation or the right rotation operation of the rotary knob type selector 2. In the figure, the middle of the operation is the N range, and the rest is the R range or the D range. “+” And “−” indicate a shift-up operation or a shift-down operation in the sequential D (drive) mode. “Invalid” indicates a state in which the operation of the rotary knob type selector 2 is permitted but the effect of the shift operation or the remote operation does not occur, and “non-movable” indicates a state in which the operation of the rotary knob type selector 2 is not permitted. ing.

  In addition, in the fourth column “pressing operation” in Table 1, “P / N” can select either the P range or the N range depending on the pressing operation, such as the difference between normal pressing and long pressing. It shows what you can do. On the other hand, “START / STOP” can be used only when “START” is used when the engine is off, and only “STOP” can be used when the engine is on. It shows what you can do.

  As described above, each shift range pattern is as shown in Table 1 and the corresponding drawing of each pattern. Among them, an eighth shift range pattern out of the fifth to eighth, a ninth shift range pattern, an eleventh shift range pattern out of the eleventh and twelfth, which require a special mechanism, The thirteenth shift range pattern of the thirteenth and fourteenth and the fifteenth shift range pattern of the fifteenth and sixteenth will be described in detail.

  As shown in FIG. 8, the eighth shift range pattern is an array of D range, N range, and R range in order from the right, like the first shift range pattern shown in FIG. The difference between them is the size of the N-range region. The range of the N range is set in a range where the rotation angle of the rotary knob type selector 2 is approximately −30 degrees to +30 degrees, with clockwise rotation as a positive rotation. Various methods can be cited as means for producing this difference. As an example, it can be realized by controlling the feeling of moderation by the actuator 4 described later and shown in FIG.

  The four shift range patterns 9A to 9D change the shift range pattern that can be selected thereafter depending on the selected position, and the positions that can be selected by right rotation, left rotation, and pressing change. The shift range pattern shown in FIG. 9A is a case where the P range is selected, and is set so that the D range is selected by right rotation and the N range is selected by left rotation. The shift range pattern shown in FIG. 9B is a case where the D range is selected, the N range is selected by left rotation, and the P range is selected by pressing. Note that the clockwise rotation operation is restricted and set to an immobile state. Further, the shift range pattern shown in FIG. 9C is a case where the R range is selected, and the N range is selected by rotating right, and the P range is selected by pressing. Note that the counterclockwise rotation operation is restricted and set to an immobile state. Further, the shift range pattern shown in FIG. 9D is a case where the N range is selected, and is set so that the D range is selected by the right rotation and the R range is selected by the left rotation.

  As shown in FIG. 11, the eleventh shift range pattern is a pattern when the sequential D (drive) mode, which is an accompanying mode of the D range, is selected. In this pattern, when the rotary knob type selector 2 is rotated to the right from its neutral position, a shift-up operation (+) is set. On the contrary, when the rotary knob type selector 2 is rotated counterclockwise from its neutral position, the shift down operation (−) is set.

  As shown in FIG. 13, the thirteenth shift range pattern is a pattern when the automatic travel mode that is an accompanying mode of the D range is selected. In this pattern, the electrical signal based on the rotation operation is not transmitted or interrupted so that the effect of the shift operation does not occur even if the rotary knob type selector 2 is rotated clockwise or counterclockwise from the neutral position. The rotation operation is set to be invalid.

  In the thirteenth shift range pattern, the pressing operation of the rotary knob type selector 2 is set to be invalid, but in the fourteenth shift range pattern, as shown in FIG. The operation is set so that a shift operation to the N range is possible.

  As shown in FIG. 15, the fifteenth shift range pattern is a pattern obtained when the automatic travel mode, which is an accompanying mode of the D range, is selected, like the thirteenth shift range pattern. In this pattern, the rotary knob type selector 2 is set in a non-moving state so as to limit the right rotation or the left rotation from the neutral position. This setting is realized by making the counter-operation force of the actuator 4 described later greater than the operation force of the operator.

  In the 15th shift range pattern, the pressing operation of the rotary knob type selector 2 is set so as not to move. This can be realized by a not-shown limiting member or the like that is interposed below the push rod 12 in the axial direction shown in FIGS. 17 and 18 to physically limit the movement thereof. On the other hand, as shown in FIG. 16, the sixteenth shift range pattern is set so that the shift operation to the N range is possible by the pressing operation.

  As shown in FIGS. 17 and 18, the first detection means 3 is a member that detects the rotational movement of the rotary knob type selector 2 and specifies a desired shift range. As the first detection means 3, various sensors can be adopted as long as the sensor can detect the rotational movement of the rotary knob type selector 2 such as a rotary encoder.

  As the first detection means 3 according to the present embodiment, as shown in FIG. 18, the substrate 9 is interposed between the lower end surface of the rotary shaft 8 of the rotary knob type selector 2 standing from the substrate 9 and the surface of the substrate 9. Magnetic sensors such as MR elements and Hall elements embedded in the magnetic field are used. In this case, a magnet (not shown) is embedded in the lower end surface of the rotating shaft 8. A plurality of magnets and magnetic sensors are preferably arranged along the lower end surface of the rotating shaft 8.

  The second detection means 7 is a member that detects a pressing operation of the rotary knob type selector 2. As the second detection means 7, various sensors can be adopted as long as the sensor can detect the pressing operation of the rotary knob type selector 2.

  As the second detection means 7 according to the present embodiment, a microswitch arranged on the surface of the substrate 9 and passing through the center of the rotating shaft 8 is used as shown in FIG. In this case, the microswitch is switched by the push rod 12 which is in contact with the lower surface of the rotary knob type selector 2 and passes through a hole provided in the center of the rotary shaft 8.

  The actuator 4 is a member that governs the rotational movement of the rotary knob type selector 2. Various actuators can be used as the actuator 4 as long as the rotary knob type selector 2 can be inhibited or supported. In the present embodiment, an electric motor that is provided coaxially with the rotating shaft 8 and connected via a gear 11 that is integrally formed with the rotating shaft 8 is used. Then, the rotary knob type selector such as prohibiting the rotational movement of the rotary knob type selector 2 or supporting the opposite by changing the rotation direction and the rotational force of the electric motor according to the state of the shift operation. The control governing the rotational motion of 2 is performed by an electric motor.

  Based on the information obtained from the first detection means 3, the control unit 5 performs actuator control as prevention, support, and response of the shift operation by a reaction force applying operation for the shift operation. The actuator 4 has a built-in rotation sensor that detects the rotation position by a rotary encoder or the like. The first detection means 3 is used to detect the rotation of the rotary encoder and the like, thereby detecting the rotation position. It is good. Here, the rotary knob type selector 2 generates a force in the rotation direction corresponding to the rotation of the knob as shown in FIGS. This rotational force can be applied to the rotary knob type selector 2 as an operation reaction force, and based on the information obtained from the first detection means 3, a reaction force application operation as a prevention, support, and response to a shift operation. Can be performed. For example, in order to prevent the shift operation from the D range to the R range during forward movement, the actuator 4 generates a force (reverse operation force) that inhibits the rotation of the rotary knob type selector 2 in the rotation direction for selecting the R range. The control of the unit 5 corresponds to this example.

  In the present embodiment, the “information obtained from the first detection means 3” is the rotation direction and shift range of the rotary knob type selector 2. Further, the prevention, support, and response of the above-described shift operation are specifically as shown in Table 2 and the following description.

  First, prevention of the shift operation will be described. As shown in Table 2, the control unit 5 performs a shift operation from the P range to another range that does not involve a brake operation (in Table 2, the D range during right rotation and the R range during left rotation), and the brake from the N range. Shift operation to the R range without operation (in Table 2, it is a left rotation operation), shift operation from the D range to the R range (in Table 2, it is a left rotation operation), or R In the shift operation from the range to the D range (in FIG. 2, the operation is a clockwise rotation), it is preferable that the actuator 4 performs a control for prohibiting the rotational movement of the rotary knob type selector 2 as a prevention of the shift operation. .

  The control in which the actuator 4 prohibits the rotational movement of the rotary knob type selector 2 is, for example, when the D range is selected, the first detection means 3 performs an operation of rotating the rotary knob type selector 2 to the left (that is, the R range). When a slight shift operation is detected, the electric motor serving as the actuator 4 performs control to prohibit its free rotation. As a result, a reverse operation force is generated in the rotary knob type selector 2 as a reaction force applying operation, so that the shift operation from the D range to the R range cannot be performed.

  Next, support for the shift operation will be described. When the control unit 5 performs a shift-up operation or a shift-down operation in the sequential D mode as shown in FIG. It is preferable to perform control to make it smaller.

  For example, as shown in FIG. 19, in the normal mode of the D range, when the rotary knob type selector 2 is rotated at a rotation rate of 100%, the rotary knob type selector 2 comes into contact with a rotation stopper (not shown). The rotation stops.

  On the other hand, as shown in FIG. 20, in the sequential D mode, for example, by rotating the rotary knob type selector 2 with a rotation rate of, for example, 50%, the electric motor serving as the actuator 4 can further rotate freely. Prohibit control. As a result, a reverse operation force is generated in the rotary knob type selector 2 as a reaction force applying operation at a predetermined rotation rate or higher, so that the rotation amount of the rotary knob type selector 2 is reduced and a quick shift up operation or shift down operation (ie, shift Operation support).

  Next, the response of the shift operation will be described. The control unit 5 is configured so that when a normal shift operation is performed, the actuator 4 performs control to give a sense of moderation to the rotary knob type selector 2 as a response to the shift operation by a reaction force applying operation. Preferably it is.

  For example, as shown in FIG. 21, in the case of a shift operation from the N range to the D range and the switching occurs, for example, at a rotation rate of 50% of the rotary knob type selector 2, the rotation rate of the rotary knob type selector 2 is 50%. Control is performed to increase the counter-operation force by the electric motor that becomes the actuator 4 so that the rotational force required for the rotational operation gradually increases until the time is reached. Then, when the rotation rate of the rotary knob type selector 2 is 50% and the rotational force of the rotary knob type selector 2 exceeds the counter operation force Fd, the actuator 4 performs control to weaken the counter operation force at once. As a result, moderation can be generated as the reaction force application operation, and the actuator 4 can impart moderation to the shift operation of the rotary knob type selector 2 to the D range.

  Further, as shown in FIG. 21, based on the above principle, a similar moderation feeling can be given to the rotary knob type selector 2 even in the shift operation from the N range to the R range. However, in order to prevent an unexpected sudden retreat, the rotation rate of the rotary knob type selector 2 required for switching from the N range to the R range is changed to the rotation rate of the rotary knob type selector 2 required for switching from the N range to the D range. It is preferable for safety to set a larger value. In the present embodiment, the rotation rate of the rotary knob type selector 2 required for switching from the N range to the R range is set to 80%, for example.

  For the same reason as described above, the counter-operation force Fr of the actuator 4 to the rotary knob type selector 2 in the shift operation to the R range is the counter-operation force of the actuator 4 to the rotary knob type selector 2 in the shift operation to the D range. It is preferable that it is set larger than Fd.

  Furthermore, when normal operations such as the shift operation from the N range to the D range and the shift operation from the N range to the R range are performed correctly, the operator is notified that the operation has been performed correctly. It is preferable to use and inform. Therefore, it is preferable to control the actuator 4 so as to vibrate the rotary knob type selector 2 by performing the control to quickly and alternately switch the rotation direction of the electric motor serving as the actuator 4.

  In addition, when providing the function to return the rotary knob type selector 2 to the home position HP, a torsion spring (not shown) may be used inside the rotary shaft 8. Further, the rotary knob type selector 2 may be forcibly rotated to the home position HP by the actuator 4. In this case, the position associated with the rotation of the actuator 4 can be detected by a rotation angle detecting means such as a rotary encoder, and based on the detection result, the position can be automatically returned to the origin (home position HP) of the rotary encoder. As a result, a momentary structure in which a so-called momentary operation is performed in which the operator automatically returns to the home position HP when the operator releases the rotary knob type selector 2.

(Operation of the speed change operation device according to the embodiment of the present invention)
As shown in FIG. 1, the shift operation device 1 of the present embodiment mainly includes a shift range changeover switch 6 that switches a shift range pattern that can be selected by the rotary knob type selector 2. As a result, even in the speed change operation device 1 employing the rotary knob type selector 2, it is possible to select a large number of shift range patterns as shown in Table 1 and FIGS.

  Further, the shift range patterns that can be switched by the shift range changeover switch 6 of the present embodiment are a large number of shift range patterns as shown in Table 1 and FIGS. 1 to 16. Thereby, an appropriate shift range and remote operation can be performed from the rotary knob type selector 2 according to various driving situations.

  In the present embodiment, as shown in FIGS. 17 and 18, the following can be considered based on the information obtained from the actuator 4 that controls the rotational movement of the rotary knob type selector 2 and the first detection means 3. And a control unit 5 that controls the actuator 4 in order to take preventive measures, support, response, and other measures.

  Thereby, since the actuator 4 can follow the shift operation performed by the operator of the rotary knob type selector 2, a safe and comfortable shift operation can be provided to the operator. Specifically, a great sense of security that an erroneous shift operation never occurs for the operator of the rotary knob type selector 2, and a comfortable feeling that a quick shift operation is possible for the operator of the rotary knob type selector 2. Can be given. In addition, since the actuator 4 can prompt the operator of the rotary knob type selector 2 to confirm the operation, the operator of the rotary knob type selector 2 can be given a sense of security that the shift operation has been performed reliably. .

  Further, as shown in Table 1 and FIGS. 15 and 16, the control unit 5 of the present embodiment allows the actuator 4 to be a rotary knob type selector when the D range is switched to the automatic travel mode by the shift range changeover switch 6. Control is performed so as to prohibit the rotation operation of No. 2. Thereby, an erroneous operation from the automatic travel mode to another shift range is prevented, and since the rotary knob type selector 2 is stationary, the operator can confirm by touch that the automatic travel mode is in the automatic travel mode.
