Next, the routine of the shift range / gear position setting control will be described with reference to flowcharts shown in FIGS. In the figure, Si (i = 1, 2, 3,.
...) show each step. When this control is started upon turning on the ignition switch, necessary initial settings are first executed (S1), and a vehicle speed signal, a throttle opening signal, a shift position signal, switch signals of the switches 30 to 33, and the like are read (S2). It is determined whether the selected range is the P range, the R range, or the N range (S3). If Yes, the hydraulic circuit 41 of the automatic transmission is controlled according to the selected range (S4). If the selected range is not the P range, the R range, or the N range, that is, if the D range is selected, S5 and subsequent steps are executed. First, it is determined whether or not the first detection switch is ON (S5).
When the operation is made to the reference position of the range (the position at the rear end of the main gate), the hold flag HF is reset (S
6) In S4, automatic shift control of the hydraulic circuit 41 in the D range is executed.

When the first detection switch 31 is OFF, that is, when the select lever 5 is operated to the sub-gate 13, it is determined whether the hold switch 30 is ON (S7). Hold switch 3
It waits until 0 is turned off (S8), and when it is turned off, it moves to S9. In S9, it is determined whether or not the hold flag HF has been set. If the hold flag HF has been set, it is reset (S10), and if it has been reset, it is set (S11). That is, each time the hold switch 30 is operated, the setting / resetting of the hold flag HF is alternately switched. Next, the hold flag HF
Is determined (S12), and if it is set, the first position P1 or the second position P of the select lever 5 is determined in S13 to S24.
By performing the operation to 2, the gear position setting control for shifting the gear position by one step up or down by one step is executed, and if the gear position is reset, the first position P1 or the second position Position P2
The shift range setting control for increasing or decreasing the shift range is executed by the operation of.

The gear position setting control will be described with reference to the flowchart shown in FIG. 7 and FIG. Whether the second detection switch 32 is ON, that is, the select lever 5
It is determined whether the operation has been performed to the position P1 (S1).
3) In the case of Yes, the selector lever 5 returns to the neutral position and waits until the second detection switch 32 is turned off (S14). It is determined (S15) that if I = 5, it cannot be further shifted up, so that I = 5 is set (S16). If not I = 5, the shift speed I is shifted up by one stage. (S17). For example, if the current gear I is the third gear, the gear is switched to the fourth gear.

When the second detection switch 32 is OFF, it is determined whether the third detection switch 33 is ON, that is, whether the select lever 5 has been operated to the second position P2 (S18), and Yes. In this case, the select lever 5 is returned to the neutral position, and the third detection switch 33 is
It waits until the FF operation is performed (S19). When the FF operation is performed, it is determined whether or not the current gear I is I = 1 (S2).
0), if I = 1, no further downshift is possible, so I = 1 is set (S21). If I = 1, the gear I is shifted down by one step (S22). For example, if the current gear I is the third gear, the gear is switched to the second gear. When the second detection switch 32 and the third detection switch 33 are OFF, that is, when the select lever 5 is held at the neutral position, the current gear I is set as the next gear I (S23). . When the shift speed I is set in this way, the hydraulic circuit 41 of the automatic transmission is controlled so as to attain the shift speed I set in S24.

Next, regarding the shift range setting control,
This will be described with reference to the flowchart shown in FIG. 8 and FIG. It is determined whether or not the second detection switch 32 is ON, that is, whether or not the select lever 5 has been operated to the first position P1 (S25). In the case of Yes, the select lever 5 is returned to the neutral position. It waits until the second detection switch 32 is turned off (S26). When the second detection switch 32 is turned off, it is determined whether or not the current gear stage I is I = 5 (S27).
In the case of 5, the shift range R that can be shifted cannot be set larger than this, so that the shift range R is set to R = 1 to 5 (S28), and if not I = 5, the shift range R is expanded. R = 1 to (I + 1) is set (S2
9). For example, when the current gear stage I is the third speed, the automatic shift control of the gear stage can be performed in the range from the first gear to the fourth gear.

If the second detection switch 32 is OFF, it is determined whether the third detection switch 33 is ON, that is, whether the select lever 5 has been operated to the second position P2 (S30), and Yes. In this case, the select lever 5 is returned to the neutral position, and the third detection switch 33 is
It waits until the FF operation is performed (S31), and when the FF operation is performed, it is determined whether or not the current gear stage I is I = 1 (S3).
1) In the case of I = 1, the shift range R that can be shifted cannot be set any smaller, so the shift range R is set to R = 1 (S32). R = 1 to (I-1) is set for reduction (S33). For example, when the current gear I is the third gear, the automatic gear can be controlled between the first gear and the second gear.

When the second detection switch 32 and the third detection switch 33 are OFF, that is, when the select lever 5 is held at the neutral position, the current shift range R is set as the next shift range R. (S34). When the shift range R is set in this manner, the shift speed is set according to the operating state and the like within the shift range R by the automatic shift control, and the hydraulic circuit 41 of the automatic transmission is controlled (S3).
5).

-Eight lamps 53 provided corresponding to each of the characters 4 and 5 are provided, and these eight lamps 53 are connected to the control unit 40. The display plate 52
Of the characters P, R, and N indicate the range of the automatic transmission.
Is operated, the corresponding lamp 53 is lit and the current range is displayed. The characters 1 to 5 indicate the gear positions of the automatic transmission. The lamps 53 corresponding to the gears that can be switched in the range, that is, five characters of the first to fifth speeds, are turned on.

On the other hand, if the select lever 5 is operated to the neutral position while the shift range selection mode is set, D
As in the case of the range, the lamps 53 corresponding to the characters 1 to 5 are turned on, and when the neutral position is operated to the first position P1 or the second position P2, the shift range R is set.
At this time, the lamp 53 of the changeable gear is turned on.
When the gear position selection mode is set at the neutral position, the ramp 5 corresponding to the current gear position in the D range is set.
3 is turned on and the select lever 5 is moved to the first position P1.
Alternatively, when the gear is switched by operating to the second position P2, the lamp 53 corresponding to the set gear is turned on. As a result, the shift range or the shift speed selected by the select lever 5 can be easily confirmed.

Next, the operation of the operation device 1 will be described. By rotating the select lever 5 in the front-rear direction along the main gate 12, the automatic transmission is mechanically operated via the lever member 8 and the push-pull wire 9, and the shift range of the automatic shift is PR. Set to the desired range of ND On the other hand, when the select lever 5 is rotated from the D range to the neutral position via the guide portion 13a,
The engagement between the notches 6a and 7a and the restricting portion 4b is released,
The mechanical connection between the operating device 1 and the automatic transmission is released. If the hold switch 30 is not operated in the neutral position, the shift range selection mode is set and the D range is maintained. In this state, the select lever 5 is moved from the neutral position to the first position P1 or the second position P2. Is operated, the shift range R is switched.
On the other hand, when the shift position selection mode is set by operating the hold switch 30 in the neutral position, the first position P
The current gear is set to 1 by operating the select lever 5 to 1.
The current gear is shifted down by one step by operating the select lever 5 to the second position P2.

As described above, since the selection of the shift speed and the selection of the shift range can be performed by the common sub-gate 13, the range positions such as the first and second ranges set along the main gate 12 can be omitted. The required space for the sub-gate 12 and the sub-gate 13 can be reduced, and the entire operation device 1 can be made compact. When the guide portion 13a is in the first position P1 (the second detection switch 3) from the D range.
2nd position P from D range rather than the operation to 2)
Since the operation to the second (third detection switch 33) is configured to be easier to operate, a downshift operation such as an engine brake can be easily performed. Select lever 5 is D
When the shift lever is moved to a position corresponding to the range, the first detection switch 31 is turned ON to cancel the gear position selection mode, so that the hold switch 30 is erroneously operated while the select lever 5 is located in the main gate 12. Is operated to set the gear position selection mode, the first detection switch 31 is operated to cancel the gear position selection mode when the select lever 5 is operated from the D range to the sub-gate 13. That is, only when the select lever 5 is in the sub-gate 13, the shift range selection mode or the speed selection mode can be set by operating the mode selection switch, so that erroneous operation of mode selection can be reliably prevented.
