Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift control device, and more particularly to a shift control device for shifting an automatic transmission or a semi-automatic transmission.

[0002]

2. Description of the Related Art A vehicle is provided with an automatic transmission, a semi-automatic transmission or a manual transmission in order to convert the driving force of a mounted engine as required in accordance with running conditions and to extract the driving force. A shift control device for shifting the speed of the machine is provided.

In an automatic or semi-automatic transmission,
In recent years, there is a structure in which a shift lever can be operated and a manual operation can be performed to shift up and down during forward running, and in this case, as shown in FIG. Operation panel 1
At 06, a pattern groove 108A for automatic transmission, a pattern groove 108B for switching, and a pattern groove 108C for manual transmission are continuously formed. Thereby, the shift lever 104
Performs a turning operation for automatic shifting in the front-rear direction of the vehicle in the automatic shifting pattern groove 108A, and temporarily shifts in the switching pattern groove 108B with the rotating direction for automatic shifting in the manual operation. The vehicle is rotated in the right and left direction at right angles, and thereafter, in the manual transmission pattern groove 108C, a rotation operation for manual transmission is performed in the front-rear direction parallel to the rotation for automatic transmission.

The shift control device 102 includes a parking (parking) position (P), a reverse running (reverse) position (R), a neutral (neutral) position (N) as each position of the shift lever 104.
The forward running position (D), the upshift position (+), and the downshift position (-) are detected,
The signal of each position is output to the control means (not shown). In such a shift control device 102,
When detecting each position of the shift lever 104,
Broadly speaking, first, a structure in which each position is detected by a shift switch attached to the automatic transmission by a shift cable that mechanically operates a parking mechanism on the automatic transmission side in response to the operation of the shift lever 104, and In addition, all positions of the shift lever 104 are
There is a structure that detects on the side.

[0005] Further, as such a shift control device,
For example, JP-A-11-25806 and JP-A-61-25806
157855 and JP-A-2000-108707. Japanese Unexamined Patent Application Publication No. 11-25806 discloses a switch contact structure for detecting a position of a shift lever on a first lever route and a switch for detecting a position of a shift lever on a second lever route. Is constructed on the same container to reduce the number of parts. JP-A-61-15
Japanese Patent Application Publication No. 7855 discloses a manual transmission for an automatic transmission, in which a shift lever is separated from a manual valve and operably mounted along a left and right pattern connected to a linear pattern. The position is set, and each switch operated at the arrival of the shift lever is provided at this speed position, and the selection of the friction element is performed so that the corresponding speed can be obtained by the signal from these switches, and the driver performs the operation. The gear can be manually switched to a desired gear. JP 2000-10870A
The shift described in Japanese Patent Application Laid-Open Publication No. 7-37107 allows a shift operation to be performed in at least three positions in one of the width direction and the front-rear direction of the vehicle, and allows the shift operation to be performed in the other direction in the width direction and the front-rear direction of the vehicle at the three positions. Even in a shift lever device having a complicated shift pattern, such as a lever device, all the required detection positions are detected by a minimum of three switches including a first link switch group and a second link switch group.

[0006]

However, conventionally, in a conventional shift control device, in a case where all the positions of the above-described second shift lever are detected on the shift control device side, the shift lever is not operated during manual operation. Since it turns right and left and falls, it is difficult to detect the signal for manual shifting.In addition, a special manual shifting detecting mechanism is required, which increases the number of parts and complicates the structure. In addition, there has been a disadvantage that it is expensive.

[0007]

SUMMARY OF THE INVENTION Therefore, in order to eliminate the above-mentioned disadvantages, the present invention provides a rotation for automatic transmission and a rotation for manual transmission parallel to the rotation direction for automatic transmission. In a shift control device provided with an operable shift lever,
When the shift lever is in a rotation position for automatic shifting, a position detection unit that detects a position of the shift lever and outputs a signal is provided, and the shift lever is in a rotation position for manual shifting. A rotation detection unit for detecting rotation of the shift lever and outputting a signal; providing the position detection unit and the rotation detection unit on the same position detection switch body; A rotation position detection switch for determining whether the rotation position is a moving position or a rotation position for manual shifting; and an operation lever that presses and operates the rotation position detection switch is provided on the shift lever. When the switch determines that the shift lever is in the rotation position for automatic shifting, the signal from the rotation detection unit is invalidated, and the rotation position detection switch causes the signal to be invalidated. Shift lever is when it is determined that the rotational position for manual shifting, characterized in that a control means for the shifting operation as a valid signal from the rotation detection unit.

[0008]

6, when the shift lever 4 is determined to be in the rotation position for automatic shifting, the signal from the rotation detection unit 76 is invalidated.
Is determined to be the rotation position for manual shifting, the signal from the rotation detecting section 76 is made effective to perform the shifting operation.

Next, the operation of the first embodiment will be described.

In the case of automatic shifting, when the shift lever 4 is rotated linearly in the front-rear direction within the automatic transmission pattern groove 12A, the positioning operation lever 52 is rotated in the front-rear direction, and the slide pin 94 is arcuate. By moving in an arc shape in the long hole 84 and the contact electrode 90 being in contact with any one of the contacts 86, the signal output from the position detection unit 74 is output to the control means 92.

On the other hand, in the case of manual operation,
Once the shift lever 4 is turned in the left and right direction within the switching pattern groove 12B, the shift lever 4 is tilted in the left and right direction, so that the turning position detection switch 96 determines the turning position of the manual shift, and When the lever 4 is rotated back and forth in the manual transmission pattern groove 12C, the contact electrode 9
When 0 is in contact with one of the shift-up contact 86M-1 and the shift-down contact 86M-2, a signal at that position is output to the control means 92.

When the rotation position detecting switch 96 determines that the shift lever 4 is in the rotation position for automatic shifting, the control means 92 invalidates the signal from the rotation detecting section 76 and detects the rotation position. When the switch 96 determines that the shift lever 4 is in the rotation position for manual shifting, the signal from the rotation detection unit 76 is validated and the transmission is shifted.

In the first embodiment, the position detection unit 74 and the rotation detection unit 76 are provided on the same position detection switch body 78, and the shift lever 4 is turned to the automatic transmission rotation position or to the manual transmission. A rotation position detection switch 96 for determining whether the rotation position is the rotation position is provided, and a manual switch operation lever 96 as an operation lever for pressing the rotation position detection switch 98 is connected to the shift lever 4 and provided. When the detection switch 96 determines that the shift lever 4 is at the rotation position for automatic shifting, the signal from the rotation detection unit 76 is invalidated. When it is determined that the shift lever 4 is in the ON position, the control means 92 for making the signal from the rotation detecting section 76 effective and performing the gear shifting operation is provided. The rotation position for gear shifting and the rotation position for manual gear shifting can be detected by one position detection switch body 78, thereby facilitating detection of a signal for manual gear shifting during manual operation, In addition, a special manual gear detection mechanism is not required, so that the number of parts can be reduced, the structure can be simplified, and the cost can be reduced.

In the position detecting section 74,
Since the shift-up contact 86M-1, which is a rotation detection contact for manual shifting, is provided between the neutral detection contact 86N and the forward shift position detection contact 86D, the arrangement of the position detection contacts of the shift lever 4 is arranged.

Parts can be integrated, productivity and assemblability can be improved, and costs can be reduced.

Further, the position switch actuating lever 52 for actuating the position detecting section 74 moves in an arc without interlocking with the tilting of the shift lever 4 in the left-right direction during manual operation. Since the position detecting section 74 is operated by the operation of the slide pin 52 and the slide pin 94, all the positions can be detected by one position detecting switch body 78. Therefore, the configuration is simple and the cost is low.
Weight can be reduced.

Further, the manual switch operating lever 96
Since the rotation detecting section 76 can be energized at all times during the operation to the shift-up position and the shift-down position, the neutral position can be substituted for the shift-up position, and the functionality is excellent and the cost is low. be able to.

FIG. 13 shows a second embodiment of the present invention.

In the following embodiments, portions that perform the same functions as those of the above-described first embodiment will be described with the same reference numerals.

The features of the second embodiment are as follows. That is, the neutral detection contact 86N of the position detection unit 74 also serves as a shift-up contact (M +) as a rotation detection contact for manual shifting.

According to the configuration of the second embodiment, by changing the software in the control means 92, as shown in FIG. 12, only when the signal of the manual operation is detected, the electrode at the neutral position is substituted as the + side signal. It is possible to reduce the number of contacts for detecting the position of the shift lever 4, simplify the arrangement thereof, and facilitate the manufacture thereof.
