DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift operating device for an automatic transmission for a vehicle, and more particularly, to a shift operating device capable of switching a normal shift range and manually selecting a speed.

[0002]

2. Description of the Related Art Conventionally, an automatic transmission for a vehicle has a mechanical switching of a manual valve provided in a hydraulic servo control circuit for operating a frictional engagement element thereof, thereby switching a range and electronically controlling the hydraulic pressure. The solenoid valve in the servo control circuit is operated in accordance with the vehicle speed and the throttle opening to perform gear shifting by two combinations of a speed selection for selecting a specific speed stage within the predetermined range. . Then, in the D range or the lower speed range (for example, S, L range) corresponding to the forward traveling range, speed selection in each range is automatically performed. In such a shift operation device that switches a manual valve of an automatic transmission, a detent mechanism that generates an operation resistance includes a manual valve, a shift operation mechanism, and a detent mechanism that causes the driver to confirm a change in the range position with a sense of moderation during the operation. Is attached to the interlocking mechanism.

[0003] Recently, in order to realize a travel more suited to human sensibility, intentional selection of a specific speed stage is considered in consideration of the aggressive reflection of the driver's intention in the travel and the fun of driving. A shift operation device to which a manual selection mechanism for enabling a shift is added has been proposed or developed.
157855, JP-A-2-8545). All of these devices release the mechanical connection between the shift operation device and the manual valve at the time of manual selection, and use a switch to change the position or displacement of the shift lever on the gate with the position of the manual valve fixed at a certain position. It is configured to electrically detect and control the solenoid valve with the detection signal to fix the solenoid valve to a selected specific speed stage.

[0004]

However, in the above-mentioned conventional apparatus, the shift lever and the interlocking mechanism are separated at the time of manual selection, so that the detent mechanism cannot give a sense of moderation to the operation of the shift lever. Therefore, in order for these devices to exhibit a sense of moderation even at the time of manual selection, a separate detent mechanism must be added to the shift operation device. The arrangement of such a separate mechanism,
Due to the complexity of the interlocking mechanism, the size of the transmission is increased and the weight is increased.

In view of such circumstances, the present invention uses a conventional detent mechanism interposed in an interlocking mechanism between a shift operation device of an automatic transmission and a manual valve as it is, to provide a complicated special mechanism. It is an object of the present invention to provide a shift operation device that can provide the same moderation as that at the time of a range switching operation to the operation of a shift lever even at the time of manual selection without necessity.

[0006]

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a shift lever and a forward drive range.
Automatic transmission gate including the area, parallel to the automatic transmission gate
Manual selection with multiple gear positions
Intersects with both gates, and connects both gates to each other.
An automatic transmission gate, comprising:
And operation of the shift lever at the manual selection gate.
Therefore, in the shift operation device of the automatic transmission for a vehicle in which the manual valve of the automatic transmission is switched via an interlocking mechanism including a detent mechanism, each change of the manual selection gate is performed.
The speed position is arranged within a region of the forward traveling range in the automatic transmission gate . Said
In the configuration of the above, in the region of the forward travel range,
A third forward travel range is arranged, and the manual selection
One of the gear positions is in the first forward travel range position.
And the automatic transmission gate of the communication gate and
The crossing position with the manual selection gate is determined by the second forward traveling.
The other position of the manual selection gate coincides with the range position.
The gear position coincides with the third forward travel range position.
It is effective to adopt a configuration arranged at each position.

[0007]

In the shift operation device for a vehicle automatic transmission according to the present invention having such a configuration, the gate for manual selection and the gate for automatic transmission are arranged in parallel , and each of the gates for manual selection is Since the gear position is within the forward travel range of the automatic shifting gate, the shift at the manual selecting gate is not possible.
By operating the shift lever, the forward travel
Interlocking mechanism similar to the operation of the shift lever in the
Since the movement occurs, the shift of the hydraulic pressure by the manual valve through the interlocking mechanism is always performed by the operation of the shift lever during manual selection , similar to the switching of the forward travel range during automatic shifting.
And the detent mechanism also operates. The operation of the detent mechanism gives a sense of moderation to the operation of the shift lever.

Therefore, according to the present invention, a complicated special mechanism is required by using the detent mechanism conventionally provided in the interlocking mechanism between the shift operating device of the automatic transmission and the manual valve as it is. In addition, even at the time of manual selection of each shift speed, it is possible to bring the same sense of moderation to the operation of the shift lever as at the time of the range switching operation. Also, by operating the shift lever at the manual selection gate,
Since the manual valve is also switched , hydraulic control for shifting is possible even at the time of manual selection, and vehicle traveling at any speed stage in the forward traveling range is possible. Further, a common use of the interlocking mechanism and the hydraulic control device can be achieved with a transmission that does not have a manual selection mechanism.
