Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a shift device, and more particularly to a shift-by-wire type shift device.

[0002]

2. Description of the Related Art Conventionally, in an automobile equipped with an automatic transmission, a shift position of the automatic transmission is designated by operating a shift lever of the shift device. The shift lever protrudes into the vehicle interior so as to easily transmit a predetermined operating force using a lever.

The mechanism for locking the shift lever is such that the shift lever cannot be moved to another position unless the shift lever is locked in the parking position (parking position) and is operated by another operation, for example, a brake pedal operation. There was something to do. For example, in the shift lever device disclosed in JP-A-10-59132, the shift lever is provided so as to be able to reciprocate a linear shift gate, and a parking position (parking position) is assigned to one end of the shift gate. When the shift lever is located at the parking position, a lock pin driven by an actuator is applied to an engagement protrusion formed on the shift lever, and the shift lever is locked immovably from the parking position to another position. .

In recent years, as a shift device, a so-called shift-by-wire automatic transmission, in which a switching operation of a shift lever is converted into an electrical switching signal, an actuator is operated by the signal, and a manual shift valve is switched by the actuator. Machine is being developed. In a shift-by-wire automatic transmission, a shift lever can be operated with a light force to select a shift position, and the shift range can be easily switched by an electrical switching signal.

[0005]

However, since the shift lever of the shift-by-wire automatic transmission can be operated with a light force, even if there is no intention to operate the shift lever, the shift lever protruding into the space inside the vehicle can be operated by the occupant. There is a risk that the shift lever will be moved by a light touch of the body of the user, and a signal of the shift operation will be transmitted. For example, during forward running of the vehicle, there is a possibility that the shift lever is moved to the selected position indicating the retreat state, and a signal for switching to the retreat state is transmitted.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a shift device capable of reducing the amount of selection operation means protruding into the vehicle interior space and preventing malfunction.

[0007]

According to a first aspect of the present invention, there is provided a shift device having a selection operation means operated for an automatic transmission of a vehicle. The means comprises a generally dome-shaped knob, a part of the knob protruding from the case.
According to the present invention, the selection operation means is operated by operating the knob provided at the end. Since a part of the substantially dome-shaped knob is provided so as to protrude from the case, the amount of protrusion into the vehicle interior space is reduced, and malfunction of the selection operation means is prevented.

According to a second aspect of the present invention, in the first aspect of the present invention, the knob is provided with a push button, and the automatic operation is performed by a two-stage operation of the push button operation and the knob operation. The gist is that transmission changeover signals can be transmitted. According to the present invention, since the switching signal is transmitted by the two-step operation of pressing the push button and operating the knob, malfunction of the selection operation means is further prevented.

The transmission hydraulic actuator 34 is a component of an automatic transmission (hereinafter referred to as a transmission) 41 as an automatic transmission, and includes an electromagnetic control valve (not shown) operated by an electric signal, and is supplied from a hydraulic pump. The connection state of the gear train is switched by controlling the supply and discharge of the operating oil by each electromagnetic control valve. The connection state of the gear train is a neutral state (neutral) N,
The state is switched to a parking state (parking) P, a reverse state (reverse) R, and a traveling state (drive) D in the automatic transmission mode (a traveling state (manual) M in the manual transmission mode).

The range position detector 35 is provided in the housing of the transmission 41 and is connected to the gear train (N, N).
P, R, and D (M)) are separately detected, and the detection signal is transmitted to the SBW-ECU 31.

The SBW-ECU 31 includes a microcomputer (not shown), and executes a control program stored in advance to control the shift hydraulic actuator 34 to switch the connection state of the gear train. The SBW-ECU 31 selects the selection device 1
The shift hydraulic actuator 34 is controlled on the basis of an operation signal from the controller and a detection signal from the range position detector 35.

The manual shift up switch 38 transmits a signal to the SBW-ECU 31 to switch the transmission 41 to a higher connection state when the transmission 41 is operated when the connection state of the transmission 41 is the traveling state M in the manual transmission mode, Down switch 39 transmits to SBW-ECU 31 a signal for switching transmission 41 to the next lower connection state.

Next, the operation of the shift device will be described. When the hemispheric knob 2 is located at the selected position S1 (parking state P), the SBW-ECU 31 sends the solenoid driving circuit 3
7, the lock signal L is transmitted to the solenoid 7, and the solenoid 16 is de-energized. As shown in FIG.
5 is moved to the rear second position by the urging force of the spring 26. In this state, since the engaging pieces 2f and 2g are engaged with the upper surface of the stopper plate 15, the hemispherical knob 2 is locked (parking lock) so that it cannot tilt to the other selected positions S0 and S2 to S4.

When the brake pedal is depressed in this state, the transmission of the lock signal L is stopped, the solenoid 16 is excited by the solenoid drive circuit 37, and the plunger 16a is moved forward as shown in FIGS. The stopper plate 15 is moved to the first position and the hemispheric knob 2 is unlocked.

Next, when performing a shift operation, when the driver places his hand (left hand) on the hemispheric knob 2 in the state shown in FIG. 2 and presses the button portion 7e with the palm, the button member 7 moves downward. Then, the engagement between the engagement projection 7d and the engagement recess 15h is released, and the hemispheric knob 2 can be tilted to another selected position. Then, when the driver presses the button 7e, each of the holes 2c to 2c.

The hemisphere knob 2 is tilted. Hemisphere knob 2 is in selection position S1
When the pin 11 is tilted rearward (toward the driver) from the (parking state P), the pin 11 is disengaged from the concave portion corresponding to the selected position S1 of the detent portion 3d and is engaged with the next concave portion. Therefore, the hemispherical knob 2 is tilted to the selected position S0 (neutral state N), and the SBW-
The connection state of the gear train is set to the neutral state N by the ECU 31.
Is switched to. In this state, when the user releases the hand from the hemispherical knob 2 and stops pressing the button portion 7e, the button member 7 is moved upward by the urging force of the spring 21, and the engaging protrusion 7d and the engaging recess 15h are engaged. Hemisphere knob 2
Is held at the other selected positions S1 to S4 so as not to be tilted unless a tilt operation is performed in a state where the button portion 7e is pressed.

When the hand is again placed on the hemispherical knob 2 and the hemispherical knob 2 is further tilted rearward, the pin 11
Since the hemisphere knob 2 is engaged with the concave portion following d, the hemispheric knob 2 is tilted to the selected position S2 (retracted state R), and the connection state of the gear train is switched to the retracted state R. In this state, even if the user releases the hand from the hemispherical knob 2 and stops pressing the button portion 7e, the hemispherical knob 2 is held at the selected position S2 as described above.

Similarly, when the hemispheric knob 2 is tilted to the selected position S4, the driving state is switched to D. Here, the traveling state D is a connection state in the automatic traveling mode in which a connection state having a different gear ratio in the gear train is automatically selected.
In this automatic driving mode, the SBW-EC
Transmission electronic control unit (ECT-) connected to U31
The ECU 42 switches the connection state of the gear train based on the vehicle speed and the throttle opening with known control contents. When the vehicle is tilted to the selected position S3, the driving state is switched to the traveling state M in the manual shift mode, and the connection state of the gear train is switched by operating the manual shift up switch 38 and the manual shift down switch 39.

When the hemisphere knob 2 is shifted to the selected position S1 (parking state P) again, the connection state of the gear train is switched to the parking state P and the solenoid 1
6, the stopper plate 15 is moved to the second position, and the hemispherical knob 2 is locked (parking lock), as shown in FIG.

This embodiment has the following effects. (1) Since the substantially dome-shaped hemispheric knob 2 is provided so as to partially protrude from the upper wall 3a, the amount of protrusion into the vehicle interior space is reduced as compared with a conventional shift lever or the like, and the select device 1 Malfunction is prevented.

(2) Since the hemispherical knob 2 has a substantially dome shape, it is less likely to be caught by a hand than a conventional shift lever or the like, and the erroneous operation of the select device 1 can be further prevented. (3) Since the hemispheric knob 2 is operated by hooking a finger on the holes 2c to 2e, it can be easily operated even if the amount of protrusion into the vehicle interior space is small.

(4) When the button portion 7e is pressed, the engagement between the engaging projection 7d and the engaging recess 15h is released, and the hemispherical knob 2 can be tilted. It is operated by two actions (the operation of pressing the button portion 7e and the operation of the hemispherical knob 2 itself), and the malfunction of the selection device 1 can be further prevented.

(5) When the hemispheric knob 2 is tilted to the selected position S1 (parking state P), the solenoid 16 is de-energized, the stopper plate 15 is moved to the second position, and the engagement pieces 2f, 2g and other selected positions S0, S2
Operationally locked to S4. Therefore, hemispheric knob 2
Can be simplified.

The embodiment is not limited to the above, and may be modified as follows, for example. As shown in FIG. 7, a switch 2j as a push button is provided in any one of the holes 2c to 2e (for example, the hole 2c) of the hemispheric knob 2, and the switch 2j is operated, whereby the hemispheric knob is operated. The output signal for selecting the connection state of the gear train transmitted by the operation of Step 2
May be set to be determined to be valid. For example, five AND circuits are provided on the ECU board 13, signals of the respective hall elements 24 and the switch unit 2 j are input to the AND circuit, and output signals thereof are output to the SBW-ECU 31.
In this case, since the hemispheric knob 2 is operated by the operation of the three actions obtained by adding the operation of the switch portion 2j to the operation of the two actions, the malfunction of the selection device 1 can be further prevented.

In the above case, the switches 2j may be provided in all of the holes 2c to 2e, and the setting may be made such that when all the switches 2j are pressed, the output signal is determined to be valid. In this case, malfunction of the selection device 1 can be further prevented.

A button portion 7e is provided on the hemisphere knob 2,
Instead of providing a mechanical internal structure such as the selecting device 1, the hemispheric knob may be freely tilted to each selected position. For example, a support is attached to the bottom of the case, a recess is formed on the upper surface of the support,
A substantially spherical support portion is accommodated in the concave portion, and a hemispheric knob provided with a switch portion 2j is slidably supported on the support portion. Normally, the friction between the support and the support is much greater than the friction between the hemisphere knob and the support so that the support does not rotate relative to the support when the hemisphere knob is operated. It is configured to be large. A magnet is attached to the hemispheric knob 2 at the front, rear, left and right of the lower end, an annular protrusion surrounding the support is provided at the support, and a Hall element is mounted at a position facing each magnet of the annular protrusion. I have. Then, the output signal by the operation of the hemispheric knob may be determined to be valid by the operation of the two actions of the operation of the hemispheric knob and the operation of the switch unit 2j.

In the above case, a degree of freedom may be given to the initial setting of the hemispheric knob. For example, in the parking state P, the hemispherical knob is tilted to the front according to the driver's preference, and the tilted position can be newly set as the position of the parking state P. In this case, the hemispheric knob is provided with an engagement pin,
The support portion has an engagement recess at a position facing the engagement pin. Then, when changing the initial setting of the hemispheric knob, the engaging pin and the engaging concave portion are engaged, and by tilting the hemispheric knob, the support portion is also rotated to change the initial setting.

In the above embodiment, the shift device is of a stationary type. However, the shift device may be changed to a momentary type that returns to a reference position when the operating force is released.
In this case, the selected state is not assigned to the reference position with the selected position S0 as the reference position, and the neutral state N is assigned to the selected position S3 instead of the traveling state M in the manual traveling mode.
When the hemispheric knob 2 is operated from the reference position to each of the selected positions S1 to S4, a signal for switching the connection state of the transmission 41 is transmitted.

The locking of the hemispheric knob 2 is not limited to the method of engaging the stopper plate 15, but may be another method. For example, a locking recess is formed in the spherical portion 6a, and a locking pin attached to a plunger of a solenoid is fitted into the locking recess, whereby the shaft 6 and the hemispheric knob 2 are engaged.
May be locked. In this case, not only the parking lock but also other cases can be used. For example, based on a signal from a vehicle speed sensor, the vehicle may be locked when the vehicle speed is equal to or higher than a predetermined speed in the traveling state D or the reverse state R.

In the above embodiment, the selecting device 1 is provided on the floor console F, but may be provided on the column S (shown in FIG. 4D). Further, it may be provided on the instrument panel 51 (shown in FIG. 4D).
In these cases, it is preferable to omit the mechanical configuration in the select device 1 in order to reduce the amount of protrusion of the select device 1 itself into the vehicle interior space.

The hemispheric knob 2 may be operated linearly like a conventional shift lever. The position sensor constituting the selection state detecting means is not limited to the one constituted by the magnet 23 and the Hall element 24, but may be a sliding switch, a micro switch, an optical sensor, or the like.

Next, the technical ideas that can be grasped from the above embodiment will be additionally described below. (1) In the invention described in claim 1 or 2,
Locking means is provided for locking the tilt of the knob by engagement with a contact portion provided on the bottom surface of the knob.

(2) In the invention according to any one of the first, second and technical ideas (1), the knob is provided with a hole through which a finger can be engaged. (3) In the invention according to claim 2, the shift device includes a selection state detection unit that detects a selection state of the selection operation unit, and the selection state detection unit operates the push button. Thus, the selection state of the selection operation means can be detected.
