[First Embodiment]
FIG. 1 shows a side view of the shift device 10 according to the first embodiment of the present invention as viewed from the left. In FIG. 1, the front of the shift device 10 is indicated by an arrow FR, and the upper part of the shift device 10 is indicated by an arrow UP.

The shift device 10 according to the present embodiment is installed in the vehicle, and the front, right and upper sides of the shift device 10 are directed to, for example, the front, right and upper sides of the vehicle, respectively.

As shown in FIG. 1, the shift device 10 is provided with a substantially rod-shaped lever 12 as a shift body, and a substantially cylindrical rotating shaft 12A as a rotating portion is integrally provided at the lower end of the lever 12. Has been done. The rotating shaft 12A is rotatably supported in one direction (direction of arrow A in FIG. 1) and another direction (direction of arrow B in FIG. 1) in a state where the axial directions are arranged parallel to the left-right direction. The lever 12 can be rotated (moved) within a predetermined range in one direction (front side) and the other direction (rear side) about the rotation shaft 12A. A rectangular columnar rotary protrusion 12B as a moving portion is integrally provided on the outer peripheral surface of the rotary shaft 12A, and the rotary protrusion 12B projects radially outward of the rotary shaft 12A.

The upper portion of the lever 12 extends into the passenger compartment, and the lever 12 can be rotated in one direction and the other direction while the upper end thereof is gripped by the vehicle occupant (particularly the driver). Has been done. Further, by rotating the lever 12 from one direction side to the other direction side, the shift position of the lever 12 becomes, for example, a "P" position (parking position) and a "R" position (reverse position) as predetermined positions. ), "N" position (neutral position) and "D" position (drive position) in this order.

A moderation mechanism 14 as an urging mechanism is mechanically connected to the lever 12, and the moderation mechanism 14 exerts an urging force on the lever 12 in the direction from the middle between the shift positions to each shift position. .. Therefore, when the lever 12 is arranged at each shift position, the lever 12 is held at each shift position by the urging force of the moderation mechanism 14. When the lever 12 is rotated to change the shift position of the lever 12, the moderation mechanism 14 exerts an urging force on the lever 12 in the direction opposite to the rotation direction between the shift positions. , A urging force is applied to the lever 12 in the rotation direction side.

The shift device 10 is provided with a shift detection device 16 as a shift detection unit, and the shift detection device 16 detects the rotation position of the lever 12 (rotation position of the rotation shaft 12A) and shifts the lever 12. Detect the position.

The shift detection device 16 is electrically connected to a control device 18 as a control unit of the vehicle, and an automatic transmission 20 (transmission) of the vehicle is electrically connected to the control device 18. When the lever 12 is rotated and the shift position of the lever 12 is changed (when the shift detection device 16 detects the change in the shift position of the lever 12), the automatic transmission 20 is controlled by the control device 18. The shift range of is changed to the shift range corresponding to the shift position of the lever 12.

The shift device 10 is provided with an operating mechanism 22.

The operating mechanism 22 is provided with a substantially cylindrical rotor cam 24 as a moving body, and the rotor cam 24 is provided in one direction and the other direction with the rotating shaft 12A of the lever 12 inserted coaxially inside. It is rotatably supported. A rectangular columnar working protrusion 24A as a moving portion is integrally provided on the inner peripheral surface of the rotor cam 24, and the working protrusion 24A protrudes inward in the radial direction of the rotor cam 24. The rotor cam 24 is arranged at a reference position (reference rotation position), and the operating protrusion 24A is arranged on the other side of the rotation protrusion 12B of the rotation shaft 12A so that the lever 12 is moved from the "P" position to "D". The rotating protrusion 12B is made inaccessible to the operating protrusion 24A when it is rotated within the range up to the position.

The operating mechanism 22 is provided with a motor 26 (DC motor) as a drive device, and a transmission gear 28 as a transmission member is coaxially fixed to the output shaft 26A of the motor 26. The transmission gear 28 is meshed with the outer circumference of the rotor cam 24, and when the operating mechanism 22 is operated and the motor 26 is driven, the transmission gear 28 is rotated and the rotor cam 24 is rotated. The motor 26 is electrically connected to the control device 18, and the operating mechanism 22 is operated by the control of the control device 18, and a current is supplied to the motor 26 to drive the motor 26.

A detection device 30 as a detection unit is electrically connected to the control device 18, and the detection device 30 detects the rotation position (for example, rotation angle position) of the rotor cam 24 and the rotation speed of the rotor cam 24 (for example). (Angular velocity) is detected. A first timer 32 as a first measurement unit and a second timer 34 as a second measurement unit are electrically connected to the control device 18, and the first timer 32 and the second timer 34 are respectively time T1. And the time T2 can be measured (see FIG. 2). Further, the control device 18 is electrically connected to the engine 36 of the vehicle.

Next, the operation of this embodiment will be described.

In the shift device 10 having the above configuration, when the lever 12 is arranged at each shift position, the lever 12 is held at each shift position by the urging force of the moderation mechanism 14. When the lever 12 is rotated to change the shift position of the lever 12, the moderation mechanism 14 exerts an urging force on the lever 12 in the direction opposite to the rotation direction between the shift positions. , A urging force is applied to the lever 12 in the rotation direction side.

By the way, at a predetermined opportunity (for example, when the engine 36 is stopped) when the lever 12 is arranged at a position other than the "P" position (for example, the "D" position), the automatic transmission is controlled by the control device 18. The shift range of the machine 20 is automatically changed to the "P" range (parking range).

Here, at a predetermined opportunity when the lever 12 is arranged at a position other than the "P" position, the operating mechanism 22 is operated by the control of the control device 18, and the motor 26 is positively driven. The transmission gear 28 is rotated and the rotor cam 24 is rotated in one direction. Therefore, the operating protrusion 24A of the rotor cam 24 is brought into contact with the rotating protrusion 12B of the rotating shaft 12A of the lever 12, and the rotating shaft 12A is rotated in one direction, so that the lever 12 is rotated in one direction. The lever 12 is rotated to the "P" position. As a result, the shift position of the lever 12 corresponds to the shift range of the automatic transmission 20.

Further, when the rotor cam 24 rotates the lever 12 in one direction, the moderation mechanism 14 exerts an urging force on the lever 12 on the other direction side (opposite the rotation direction) between the shift positions. After the rotation speed of the lever 12 and the rotation speed of the rotor cam 24 are reduced, the moderation mechanism 14 exerts a urging force on the lever 12 in one direction (rotation direction side) to cause the rotation speed of the lever 12 and the rotor cam. The rotation speed of 24 is increased.

When the lever 12 is rotated to the "P" position, the rotor cam 24 is rotated to the reaching position (the rotation position of the rotor cam 24 when the rotor cam 24 rotates the lever 12 to the "P" position). Is detected by the detection device 30, and the forward drive of the motor 26 is stopped and the motor 26 is reversely driven by the control of the control device 18. Therefore, the transmission gear 28 is rotated and the rotor cam 24 is rotated in the other direction, so that the rotor cam 24 is rotated (returned) to the reference position. Further, the detection device 30 detects that the rotor cam 24 has been rotated to the reference position, and the reverse drive of the motor 26 is stopped by the control of the control device 18.

Next, as described above, the processing of the control device 18 when the operating mechanism 22 is operated and the lever 12 is rotated to the “P” position by the positive drive of the motor 26 will be described (see FIG. 2).

First, in step 100, at a predetermined opportunity when the lever 12 is arranged at a position other than the "P" position, the current supply (energization) to the motor 26 is started, and the motor 26 starts the positive drive. At the same time, the measurement of the time T1 by the first timer 32 is started. Then, in step 102, the measurement of the time T2 by the second timer 34 is started.

Next, in step 104, it is determined whether or not the rotation speed of the rotor cam 24 is equal to or less than a preset predetermined speed. The predetermined speed is set to, for example, the rotation speed (may be 0) of the rotor cam 24 when the rotation of the lever 12 is substantially stopped by the occupant.

If it is determined in step 104 that the rotation speed of the rotor cam 24 is equal to or lower than the predetermined speed, the process proceeds to step 108.

When it is determined in step 104 that the rotation speed of the rotor cam 24 is higher than the predetermined speed, in step 106, the measurement of the time T2 by the second timer 34 is cleared, and the measurement of the time T2 by the second timer 34 is started from 0. After starting, the process proceeds to step 108.

In step 108, it is determined whether or not the time T1 measured by the first timer 32 is less than the first time-out time TO1 as the preset first time. The first time-out time TO1 is a time (for example, 10 seconds) longer than the time from when the current supply to the motor 26 is started until the lever 12 is rotated at a relatively low speed to reach the “P” position. Has been done.

When it is determined in step 108 that the time T1 measured by the first timer 32 is equal to or longer than the first timeout time TO1, the current supply to the motor 26 is stopped and the motor 26 stops the normal drive in step 114. To do.

When it is determined in step 108 that the time T1 measured by the first timer 32 is less than the first timeout time TO1, the time T2 measured by the second timer 34 is set to the preset second time and in step 110. It is determined whether or not the second timeout time TO2 as a predetermined time is less than. The second timeout time TO2 is set to a short time (for example, 0.15 seconds, which may be 0 seconds) which is at least less than the first timeout time TO1.

When it is determined in step 110 that the time T2 measured by the second timer 34 is less than the second timeout time TO2, it is determined in step 112 whether or not the rotor cam 24 has reached the arrival position.

If it is determined in step 112 that the rotor cam 24 has not reached the arrival position, the process of step 104 is performed again.

If it is determined in step 110 that the time T2 measured by the second timer 34 is equal to or longer than the second timeout time TO2, the current supply to the motor 26 is stopped and the motor 26 stops the normal drive in step 114. To do.

If it is determined in step 112 that the rotor cam 24 has reached the reaching position, in step 114, the current supply to the motor 26 is stopped, and the motor 26 stops the positive drive. Therefore, when the lever 12 reaches the "P" position, the positive drive of the motor 26 is stopped.

Here, according to step 100, step 108, step 112, and step 114, the motor 26 is in the normal driving state (the first operating state and the operating non-stop state of the operating mechanism 22) before the lever 12 reaches the “P” position. ) Is continued for the first time-out time TO1, the current supply to the motor 26 is stopped, and the normal drive of the motor 26 is stopped. Further, as described above, the first timeout time TO1 is longer than the time from when the current supply to the motor 26 is started until the lever 12 is rotated at a relatively low speed to reach the "P" position. Has been made. Therefore, even when the rotation speed of the lever 12 due to the positive drive of the motor 26 is relatively low due to, for example, mechanical deterioration of the operating mechanism 22, the motor 26 is before the lever 12 reaches the “P” position. It is possible to prevent the lever 12 from reaching the "P" position when the positive drive of the lever 12 is stopped.

Further, by step 102, step 104, step 106, step 110, step 112, and step 114, the rotation of the lever 12 is substantially stopped before the lever 12 reaches the “P” position (the first operation mechanism 22). When the second time-out time TO2 is continued (2 operating states), the current supply to the motor 26 is stopped. Further, as described above, the second timeout time TO2 is set to a short time that is at least less than the first timeout time TO1. Therefore, it is possible to suppress the continuation of the current supply to the motor 26 when the rotation of the lever 12 is substantially stopped (inhibited) and the rotation of the output shaft 26A of the motor 26 is substantially stopped (inhibited). It is possible to prevent the motor 26 from being damaged due to the stationary state in which the 26 generates heat, and the motor 26 can be protected.

Further, in step 104, the detection device 30 detects the rotation speed of the rotor cam 24. Therefore, before the operating protrusion 24A of the rotor cam 24 comes into contact with the rotating protrusion 12B of the lever 12, when the lever 12 is not rotated even if the rotor cam 24 is rotated, the detection device 30 rotates the lever 12. It is possible to suppress the detection of a substantially stop. As a result, even if the rotation of the lever 12 is substantially stopped, if the motor 26 does not enter a stationary state in which heat is generated, the current supply to the motor 26 is unnecessarily stopped and the lever 12 rotates to the "P" position. It can be suppressed that it is not done.

In the present embodiment, the current supply to the motor 26 is restarted after a specified time after the substantially stopped state of the rotation of the lever 12 is continued for the second timeout time TO2 and the current supply to the motor 26 is stopped. Further, after that, for example, when the substantially stopped state of the rotation of the lever 12 is continued for a time shorter than the second timeout time TO2, the current supply to the motor 26 may be stopped.

Further, in the present embodiment, the detection device 30 detects the rotation speed of the rotor cam 24. However, the detection device 30 may detect the moving speed of a moving body (for example, the output shaft 26A of the motor 26 or the transmission gear 28) that is constantly moved with the rotation of the rotor cam 24.

Further, in the present embodiment, a substantially stopped state of rotation of the lever 12 is detected based on the rotation speed of the rotor cam 24 detected by the detection device 30. However, the rotation of the lever 12 is substantially stopped based on the rotation speed of the lever 12 detected by the shift detection device 16 (detection unit) (the movement speed of the moving member that is always moved with the rotation of the lever 12 may be used). It may be detected. In this case, it is preferable that the substantially stopped state of the rotation of the lever 12 is detected based on the rotation speed of the lever 12 after the rotational power from the rotor cam 24 is applied.

[Second Embodiment]
The shift device 50 according to the present embodiment has substantially the same configuration as that of the first embodiment (see FIG. 1), but differs in the following points.

In the shift device 50 according to the present embodiment, the second timer 34 is capable of measuring the time T3 (see FIG. 4).

By the way, in general, an inrush current flows through the motor 26 immediately after the current supply to the motor 26 is started (see FIG. 3A). Further, since the winding resistance of the motor 26 has a temperature characteristic, the lower the temperature of the motor 26, the larger the current flowing through the motor 26, and the higher the temperature of the motor 26, the smaller the current flowing through the motor 26. Therefore, the inrush current to the motor 26 increases as the temperature of the motor 26 decreases, and decreases as the temperature of the motor 26 increases (see FIG. 3B).

Further, when the rotation of the output shaft 26A is substantially stopped (inhibited) while the motor 26 is being supplied with current, the current flowing through the motor 26 (stopping current, FIG. 3) occurs when the motor 26 is in a stopped state in which heat is generated. The stop current threshold IS, which is the minimum value of (see (A)), increases as the temperature of the motor 26 decreases, and decreases as the temperature of the motor 26 increases (see FIG. 3B). Further, the stop time threshold TS (including 0) as the second time, which is the time during which the state in which the stop current flows through the motor 26 can be continued until immediately before the stop state in which the motor 26 generates heat is reached, is the motor 26. The lower the temperature, the longer the length, and the higher the temperature of the motor 26, the shorter the length.

From the above, the temperature of the motor 26 can be estimated based on the inrush current to the motor 26, and the stop current threshold IS of the motor 26 and the stop time threshold TS of the motor 26 are estimated based on the estimated temperature of the motor 26. it can. Therefore, the temperature of the motor 26 can be estimated based on the inrush current to the motor 26, and the stop current threshold IS of the motor 26 and the stop time threshold TS of the motor 26 can be determined.

In the shift device 50 according to the present embodiment, when the operating mechanism 22 is operated and the lever 12 is rotated to the “P” position by the positive drive of the motor 26, the control device 18 performs the following processing (FIG. 4). reference).

First, in step 200, at a predetermined opportunity when the lever 12 is arranged at a position other than the "P" position, the current supply (energization) to the motor 26 is started, and the motor 26 starts the positive drive. At the same time, the measurement of the time T1 by the first timer 32 is started.

Then, in step 202, the maximum current flowing through the motor 26 during the period from the start of supplying the current to the motor 26 to the elapse of a specific time (for example, 0.5 seconds) is determined to be the inrush current to the motor 26 (FIG. 3 (FIG. 3). See A)). Further, in step 204, the temperature of the motor 26 is estimated based on the inrush current to the motor 26, the stop current threshold IS of the motor 26 is set, and in step 206, based on the inrush current to the motor 26. The temperature of the motor 26 is estimated, and the stop time threshold TS of the motor 26 is set.

Next, in step 208, it is determined whether or not the current I flowing through the motor 26 is equal to or greater than the stop current threshold value IS of the motor 26.

If it is determined in step 208 that the current I flowing through the motor 26 is less than the stop current threshold IS of the motor 26, after clearing the time T3 measured by the second timer 34 and setting it to 0 in step 210. In step 212, it is determined whether or not the time T1 measured by the first timer 32 is equal to or longer than the preset first timeout time TO1.

When it is determined in step 212 that the time T1 measured by the first timer 32 is equal to or longer than the first timeout time TO1, the current supply to the motor 26 is stopped and the motor 26 stops the normal drive in step 214. To do.

When it is determined in step 212 that the time T1 measured by the first timer 32 is less than the first timeout time TO1, it is determined in step 216 whether or not the rotor cam 24 has reached the arrival position.

When it is determined in step 216 that the rotor cam 24 has reached the reaching position, in step 214, the current supply to the motor 26 is stopped, and the motor 26 stops the positive drive. Therefore, when the lever 12 reaches the "P" position, the positive drive of the motor 26 is stopped.

If it is determined in step 216 that the rotor cam 24 has not reached the arrival position, the process of step 208 is performed again.

If it is determined in step 208 that the current I flowing through the motor 26 is equal to or greater than the stop current threshold IS of the motor 26, it is determined in step 218 whether or not the second timer 34 is measuring the time T3.

If it is determined in step 218 that the second timer 34 has not measured the time T3, in step 220, the measurement of the time T3 by the second timer 34 is started, and then the process proceeds to step 222.

If it is determined in step 218 that the second timer 34 is measuring the time T3, the process proceeds to step 222.

In step 222, it is determined whether or not the time T3 measured by the second timer 34 is less than the stop time threshold TS of the motor 26.

If it is determined in step 222 that the time T3 measured by the second timer 34 is less than the stop time threshold TS of the motor 26, the process proceeds to step 212.

If it is determined in step 222 that the time T3 measured by the second timer 34 is equal to or greater than the stop time threshold TS of the motor 26, the current supply to the motor 26 is stopped in step 214, and the motor 26 is positive. Stop driving.

Here, according to step 200, step 212, step 214, and step 216, the motor 26 is in the normal driving state (the first operating state and the operating non-stop state of the operating mechanism 22) before the lever 12 reaches the “P” position. ) Is continued for the first time-out time TO1, the current supply to the motor 26 is stopped, and the normal drive of the motor 26 is stopped. Further, the first time-out time TO1 is set to be longer than the time from when the current supply to the motor 26 is started until the lever 12 is rotated at a relatively low speed to reach the "P" position. .. Therefore, even when the rotation speed of the lever 12 due to the positive drive of the motor 26 is relatively low due to, for example, mechanical deterioration of the operating mechanism 22, the motor 26 is before the lever 12 reaches the “P” position. It is possible to prevent the lever 12 from reaching the "P" position when the positive drive of the lever 12 is stopped.

Further, by step 208, step 210, step 214, step 216, step 218, step 220 and step 222, the stop current (stop current threshold IS) is applied to the motor 26 before the lever 12 reaches the “P” position. When the state in which the above current) flows (the second operating state of the operating mechanism 22) continues for a time equal to or longer than the stop time threshold TS of the motor 26, the current supply to the motor 26 is stopped. Further, as described above, the stop time threshold TS of the motor 26 is set to a time during which the stop current can be continued to flow through the motor 26 until immediately before the stop state in which the motor 26 generates heat is reached. Therefore, the rotation of the lever 12 is substantially stopped (inhibited), and the rotation of the output shaft 26A of the motor 26 is substantially stopped (inhibited), so that the current to the motor 26 when the stationary current flows through the motor 26. It is possible to suppress the continuation of the supply, prevent the motor 26 from being damaged in a stationary state in which heat is generated, and protect the motor 26.

Further, in step 204, the temperature of the motor 26 is estimated based on the inrush current to the motor 26, and the stop current threshold IS of the motor 26 is set. Therefore, when the temperature of the motor 26 is low, the stop current threshold IS of the motor 26 is set to be small, so that the current to the motor 26 is unnecessary even though the motor 26 does not generate heat. It is possible to prevent the lever 12 from reaching the "P" position when the supply is stopped.

Moreover, in step 206, the temperature of the motor 26 is estimated based on the inrush current to the motor 26, and the stop time threshold TS of the motor 26 is set. Therefore, when the temperature of the motor 26 is low, the stop time threshold TS of the motor 26 is set short, so that the current to the motor 26 is unnecessary even though the motor 26 does not generate heat. It is possible to prevent the lever 12 from reaching the "P" position when the supply is stopped.

In the present embodiment, a state in which a current of the stop current threshold IS or more flows through the motor 26 continues for a time of the stop time threshold TS or more of the motor 26, and a predetermined time after the current supply to the motor 26 is stopped. , The current supply to the motor 26 may be restarted, and then, for example, when the state in which the current of the stop current threshold IS or more flows through the motor 26 continues for a time less than the stop time threshold TS of the motor 26. In addition, the current supply to the motor 26 may be stopped.

Further, in the present embodiment, the temperature of the motor 26 is estimated based on the inrush current to the motor 26, and the stop current threshold IS and the stop time threshold TS of the motor 26 are set.
