It is a longitudinal cross-sectional view which shows an example of the change lever unit provided with an example of embodiment of the change lever locking device which concerns on this invention, and passes along the center of a shift rotation axis | shaft. It is a longitudinal cross-sectional view which passes along the center of the selection rotation axis | shaft in the change lever unit of the example shown in FIG. (A) is a figure explaining operation of a change lever, (b) is a figure which shows the shift pattern of a change lever unit. It is a block diagram which shows the change lever lock control apparatus of a change lever lock apparatus. It is a figure explaining change lever lock control by a change lever lock control device. It is a figure which shows the flow of the change lever lock control method.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
FIG. 1 shows an example of a change lever unit including an example of an embodiment of a change lever locking device according to the present invention, a longitudinal sectional view passing through the center of a shift rotation shaft, and FIG. 2 shows a selection of the change lever unit of this example. It is a longitudinal cross-sectional view which passes along the center of a rotating shaft.

As shown in FIGS. 1 and 2, a change lever unit (CLU) 1 of the transmission of this example includes a unit main body 2 and an upper end opening of the unit main body 2 so as to close the upper end opening. And a case 3 detachably attached to the upper end.

  A shift rotation shaft 4 is provided in the unit main body 2 so as to be rotatable around its central axis. The shift rotation shaft 4 is provided with a select rotation shaft 5 penetrating the shift rotation shaft 4 so as to be orthogonal to the shift rotation shaft 4. Further, one end of a change lever 6 is rotatably attached to the select rotation shaft 5. Therefore, the change lever 6 can be rotated about the shift rotation shaft 4 and can be rotated about the select rotation shaft 5.

  As shown in FIGS. 3A and 3B, the shift pattern 7 of the CLU 1 in this example includes two first shift trains Si1 and second shift trains Si2 arranged in parallel with each other at a predetermined interval. And one select column Se. In that case, the first and second shift columns Si1, Si2 and the select column Se are orthogonal to each other.

  In the first shift column Si1, three ranges of parking (P), neutral (N), and reverse (R) are arranged in a line in this order. In the second shift column Si2, three ranges of drive (D), shift-up (UP), and shift-down (DOWN) are arranged in a line in this order. Further, in the select column Se, three ranges of neutral (N), drive (D) and drive holding (A / M) are arranged in a line in this order. The N range of the first shift column Si1 is the same as the N range of the select column Se, and the D range of the second shift column Si2 is the same as the D range of the select column Se.

As shown in FIG. 3A, a shift pattern hole 8 through which the change lever 6 passes is provided at the upper end portion of the case 3. The shift pattern hole 8 is a passage through which the change lever 6 passes when the change lever 6 is operated. The shift pattern hole 8 is formed in a shape corresponding to the first and second shift columns Si1, Si2 and the select column Se.

As shown in FIGS. 1 and 2, a parking lever 9 is disposed next to the change lever 6 on the shift rotation shaft 4. The parking lever 9 rotates in conjunction with the movement of the change lever 6 when the change lever 6 is operated in the first shift train Si1. Although not shown, the parking lever 9 is connected to a transmission locking means for mechanically locking a transmission (TM) such as an automatic transmission via a parking cable. When the change lever 6 is set to the P range, the parking lever 9 is rotated in conjunction with the movement of the change lever 6 to the P range, whereby the transmission lock means is operated via the parking cable, and The machine is mechanically locked.

  The parking lever 9 is separated from the change lever 6 when the change lever 6 moves from the N range of the first shift train Si1 to the D range of the second shift train Si2. Therefore, the change lever 6 is not interlocked with the movement of the change lever 6 when operated outside the first shift train Si1. Further, when the parking lever 9 is separated from the change lever 6, the parking lever 9 is locked so as to be held at the separated position by the parking lever locking means 10. When the parking lever 9 is locked by the parking lever locking means 10, the locking member 10 b operated by the solenoid 10 a enters the parking lever locking means 10 into the locking hole of the parking lever 9 and engages the parking lever 9 in the rotational direction. (The locked state of the parking lever 9 by the lock member 10b is shown by a two-dot chain line in FIG. 1).

  As shown in FIG. 1, a magnet 11 is provided at the lower end of the change lever 6 (the end of the change lever 6 on the unit body 2 side). In the unit body 2, the hall element 12 is provided so that the magnet 11 can be opposed thereto. In that case, the Hall element 12 is provided so that the center thereof is positioned on a straight line passing through the center of the select rotation shaft 5 and orthogonal to the shift rotation shaft 4. When the change lever 6 is at a position orthogonal to the shift rotation shaft 4, the center of the magnet 11 faces the center of the Hall element 12. These magnet 11 and hall element 12 constitute a change lever position detection device 13.

  The Hall element 12 in this example is a 3D Hall IC. Therefore, in the change lever position detection device 13 of the CLU 1, the Hall element 12 detects the magnetism of the magnet 11 that changes in accordance with the position of the change lever 6, and an electrical select position signal and a signal corresponding to the detected magnetism. An electrical shift position signal is output. At this time, the magnetism of the magnet 11 detected by the Hall element 12 has a certain width in each range. Therefore, in the change lever position detection device 13 of this example, a range position determination region for determining the range of the change lever 6 is set for each range in both the shift direction and the select direction. And between each range position determination area | region in an adjacent range, the range position non-determination area | region is provided so that these range position determination areas may not overlap. As the electrical select position signal and the electrical shift position signal, a voltage signal, a PWM signal, a serial communication signal, or the like is used. Therefore, the signal output from the change lever position detection device 13 is the change lever position signal of the present invention.

As schematically shown in FIG. 3A, a change lever lock device 14 is provided in the CLU 1 of this example. The change lever lock device 14 includes a solenoid 14a (corresponding to the lock member operating member of the present invention) and a change lever lock member 14b (corresponding to the lock member of the present invention) operated by the solenoid 14a. When the change lever 6 is in the P range, the solenoid 14a is de-energized, and the change lever lock member 14b locks the change lever 6 to prevent the change lever 6 from moving to other ranges than the P range. Further, when the solenoid 14a is excited by depressing the brake pedal, the change lever lock member 14b is actuated to unlock the change lever 6, and the change lever 6 can be moved to a range other than the P range. Become. The change lever locking device 14 can lock the change lever 6 by the change lever locking member 14b even in the N range of the change lever 6. The change lever lock device 14 is the same as the change lever lock device 14 known in the art, including the change lever lock device 14 described in Patent Document 2 described above. It should be noted that the solenoid 10a of the parking lever locking means 10 described above can also serve as the solenoid 14a of the change lever locking device 14. Accordingly, it is not necessary to provide a dedicated solenoid for the solenoid 13a of the parking lever locking means 10, and the increase in the number of parts can be suppressed, and the parking lever locking means 10 can be reduced in size and weight.

FIG. 4 is a block diagram showing a change lever lock control device of the change lever lock device.
As shown in FIG. 4, the change lever lock control device 15 includes a change lever position detection device 13, a brake switch 16, and an electronic control unit 17 (corresponding to the control unit of the present invention). The electronic control unit 17 in this example includes a transmission control unit (TCU: Transmission Control Unit) 19 that controls the transmission (TM) 18. The brake switch 16 includes a brake switch that turns on a brake lamp when a brake is actuated by depressing the brake pedal, and is a change lever movement permission member. Therefore, the signal output from the brake switch 16 is the change lever movement permission signal of the present invention. The change lever movement permission member is not limited to the brake switch 16 and may be any other member that outputs a signal permitting movement to another range (a range other than the P range) of the change lever 6 in the P range. Any change lever movement permission member can be used.

FIG. 5 is a diagram for explaining change lever lock control by the change lever lock control device.
As shown in FIG. 5, when the engine is stopped and the vehicle is parked, the change lever 6 is in the P range. Further, in the parking state of the vehicle, the brake switch is turned off, the solenoid 14a of the change lever lock control device 14 is de-energized, and the lock member 14b locks the change lever 6 in the P range. . Accordingly, the change lever 6 is not permitted to move to any other range than the P range (impossible to move).

  In driving the vehicle, the driver depresses the brake pedal to operate the brake in order to move the change lever 6 from the P range to the N range. Then, the brake switch 16 is turned on, and when the brake switch 16 is turned on, the solenoid 14a is excited and the lock member 14b unlocks the change lever 6. Thereby, the change lever 6 is allowed to move to a range other than the P range (movable). After unlocking the change lever 6, the driver moves the change lever 6 toward the N range.

  At this time, it is assumed that the driver moves the change lever 6 from the P range to the N range at a shift operation speed faster than the normal shift operation speed. Then, the change lever 6 moves along a straight line α shown by a solid line in FIG. When the change lever position detection device 13 detects that the change lever 6 has left (passed through) the P range position determination region, the electronic control unit 17 de-energizes the solenoid 14a again. As a result, before the change lever 6 reaches the N range position determination region, the change lever lock control device 14 enters the lockable state of the change lever 6 (shown as locked in FIG. 5).

  When the change lever 6 further moves toward the N range and reaches a predetermined position in the N range position determination region by the change lever position detection device 13, that is, the N range position, the change lever position where the change lever 6 is in a lockable state. The change lever 6 is locked by the detection device 13 and cannot move, and stops. Thereby, even if the change lever 6 is operated at a shift operation speed faster than usual as described above, the change lever 6 is held in the N range and does not move directly toward the R range.

Further, when the timer 17a of the electronic control unit 17 counts from the de-energization of the solenoid 14 and a certain time (for example, 0.5 sec) has elapsed since the solenoid 14a of the change lever lock control device 14 is de-energized, the electronic control The part 17 excites the solenoid 14a to bring the change lever lock control device 14 into the unlocked state in which the change lever 6 is not locked. As a result, the change lever 6 can move to a range other than the N range. When the driver operates the change lever 6 from the N range to the R range, for example, the change lever 6 is moved to the R range as shown by the solid line in FIG. Set to range. Thus, in the change lever lock control device 15 of this example, the change lever 6 is included in the N range position determination region (that is, while the change lever 6 is shifted from the P range to the N range). The change lever lock member 14b of the change lever lock control device 14 is brought into a lockable state of the change lever 6 for the time. Note that the predetermined time can be set so that the change lever 6 can be locked when the change lever 6 is shifted at a normal shift operation speed.

  It is assumed that the driver has moved the change lever 6 from the P range to the N range at a shift operation speed much slower than the normal shift operation speed. Then, the change lever 6 moves along a straight line β shown by a two-dot chain line in FIG. Then, after the change lever 6 is locked for the same fixed time as described above, the change lever 6 is unlocked again. At this time, it is conceivable that a predetermined time elapses before the change lever 6 enters the N-range position determination region, and the change lever 6 is unlocked. However, in this case, since the shift operation speed of the change lever 6 is slow, the change lever 6 stops even if it is not locked within the N range position determination region. Therefore, the change lever 6 hardly shifts to the R range at a stretch through the N range.

FIG. 6 is a diagram illustrating a flow of the change lever lock control method.
When the engine is driven to start the operation of the vehicle and the change lever 6 in the P range is shifted from the P range to another range, as shown in FIG. In step S1, it is determined whether or not the brake switch 16 is turned on. If it is determined that the brake switch 16 is not turned on, the process of step S1 is repeated as it is.

  If it is determined that the brake switch 16 is turned on in step S1, the solenoid 14a of the change lever lock control device 14 is excited in step S2. Thereby, the lock of the change lever 6 is released and the change lever 6 can be moved. Next, in step S3, the change lever 6 is shifted from the P range to the N range. Next, in step S4, it is determined whether or not the change lever 6 has passed the P range position determination region. If it is determined that the change lever 6 has not passed the P range position determination region, the process of step S4 is repeated as it is.

  If it is determined in step S4 that the change lever 6 has passed the P range position determination region, the solenoid 14a of the change lever lock control device 14 is de-energized in step S5. As a result, the change lever lock control device 14 is brought into a lockable state of the change lever 6. Next, when the change lever 6 reaches the N range position, the change lever 6 is locked to the N range by the lock member 14b. Next, in step S7, it is determined whether or not a fixed time has elapsed since the solenoid 14a was not excited in step S5. If it is determined that the predetermined time has not elapsed, the process of step S7 is repeated as it is. If it is determined in step S7 that the predetermined time has elapsed, the solenoid 14a of the change lever locking device 14 is energized again in step S8. Thereby, the lock of the change lever 6 by the change lever locking device 14 is released again.

  According to the change lever lock control device 14, the CLU1, and the change lever lock control method of this example, in the shift pattern in which the P range, the N range, and the R range are arranged in this order in one shift train Si1, the vehicle starts. Therefore, when the change lever 6 is shifted from the P range to the N range, the change lever 6 is locked by the change lever locking device 14 before the change lever 6 passes the N range. As a result, when the vehicle is started forward, even when the change lever 6 is operated at a shift operation speed faster than the normal shift operation speed, the change lever 6 passes through the N range and is shifted to the R range all at once. Can be prevented. Therefore, the shift operation of the change lever 6 from the P range to the D range can be simplified, and a good shift operation feeling can be obtained.

  Further, when the change lever 6 is shifted from the P range to the R range, the change lever 6 is temporarily stopped at the N range, so that the driver can recognize the position of the change lever, and from the P range to the R range. The shift operation of the change lever 6 can be performed stably and reliably.

  In addition, the change lever lock control apparatus of this invention is not limited to the above-mentioned example, A various design change is possible. For example, in the above-described example, when the change lever 6 shifts from the P range to the N range, the change lever 6 sets the P range position determination region for a certain time during which the change lever lock control device 14 locks the change lever 6. Although the time is measured from the time of separation (passing), the certain time can also be timed from the time when the change lever 6 enters the N range position determination region.

  In addition, the change lever lock control device of the present invention is any change lever lock control device as long as it has a shift pattern in which the P range, the N range, and the R range are arranged in one shift row in this order. It can also be applied to. In short, various design changes are possible within the scope of the technical matters described in the claims.

  The present invention is suitably used for a change lever lock control device that locks and controls a change lever operated to perform shift control of a transmission of a vehicle according to the present invention, a change lever unit including the change lever lock control method, and a change lever lock control method. Is possible.
