And N range lamps 33, the lamps in the range where the switch is ON are turned on.

In this case, since the speed change control is not performed, the 2AT lamps 36, 3 are set in steps S9 to S11.
At the same time, the AT lamps 37 are turned off, and the value of the target shift speed G used in the shift control is set to the value 3 as the home position. When the operation is performed in the R range, the control unit 60 sets a target so as to realize the reverse speed.

On the other hand, if it is determined in step S2 that the D range switch is ON, the process proceeds to step S12.
After turning on the D range lamp 34 in step S13, it is determined whether or not the shift limiter switch 18 has been turned ON in step S13, and if so, the shift mode is set to the 3AT mode or the 2AT mode according to the number of times of operation. . At this time, when the 3AT mode is set, the shift limit flag F13 is set to 1, and
When the 2AT mode is set, the shift limit flag F12 is set to 1.

Further, the shift limiter switch 18 is turned on.
If it has been operated, then in step S14, it is determined whether or not the cancel switch 19 has been turned ON. If it has not been operated, that is, if any of the shift modes has been set, step S15 is performed. Then, the value of the shift limit flag F13 is determined. And 2A
If T mode is set, F13 = 0, so
Next, step S16 is executed, and F12 = 1, F13 =
It is set to 0, and if it is set to the 3AT mode, in step S17, F12 = 0 and F13 = 1 are set. If it is determined in step S14 that the cancel switch 19 has been turned ON, the shift mode returns to the normal automatic shift mode between the first gear and the fourth gear. Therefore, in step S18, the shift limit flag F13,
Set both F12 to 0.

Next, the control unit 60 determines in steps S19 and S20 that the shift limit flag F1

Further, when F12 and F13 are both 0, in steps S27 to S29, both the 2AT lamp 37 and the 3AT lamp 36 are turned off and the target gear G
Is set according to the vehicle speed and the throttle opening from all the first to fourth speeds, and a signal is output to the hydraulic control circuit 63 so that the speed is realized. This gives D
In the range, the shift speed is switched according to the shift mode set by operating or not operating the shift limiter switch 18 and the cancel switch 19.

On the other hand, when the shift lever 3 is operated to the M range and the M range switch 15 shown in FIG. 2 is turned on, the control unit 60 executes steps S1 to S30 and executes the shift shown in FIG. It is determined whether or not the up switch 16 has been turned ON. And
By operating the shift lever 3 forward in the M range,
When the upshift switch 16 is turned on, it is determined in step S31 whether or not the value of the target gear G that matches the current actual gear is 4 or not.
If it is not 4, upshifting is possible, so step S
At 32, the target gear G is increased by one.

If the shift-up switch 16 has not been turned ON, it is determined in step S33 whether the shift-down switch 17 has been turned ON, and the shift lever 3 is operated backward in the M range. Accordingly, when the downshift switch 17 is turned on, it is determined in step S34 whether or not the value of the target shift speed G is 1, and if G = 1, the downshift is possible.
In step S35, the target gear G is decremented by one.

Then, a signal is output to the hydraulic control circuit 63 so that the target gear set in this way is realized, and at step S36, the M range lamp 35 is turned on.

On the other hand, when displaying the current gear position on the above-mentioned gear position indicator 38, the shift speed is determined based on the number of ON-OFF operations of the shift-up switch or the shift-down switch by the shift lever operated to the M range. When the gear is displayed on the gear display 38, when the lever is operated quickly and continuously by the lever, the ON / OFF count of the upshift switch 16 or the downshift switch 17 and the current gear position May not match.

However, the target shift stage G is determined by the shift control section 60a of the control unit 60 in accordance with the operation of the shift-up switch 16 and the shift-down switch 17.
If the target gear stage G is displayed on the gear stage indicator 38 as the current gear stage based on the signal from the shift control unit 60a, the shift up switch 16 or the shift down switch 17 of the shift lever 3 can be displayed. ON-O
The gear position based on the number of FFs is not displayed on the gear position indicator 38, but the current gear position in the automatic transmission is always accurately displayed.
