- the driver makes the shift operation of the shift lever 21 invalid by notifying a warning sound.
- the manual shift control means 51 invalidates the upshift from the eighth forward speed (highest shift speed) and the downshift from the first forward speed (lowest speed).
- the manual shift control means 51 is used when it is not desirable to maintain the gear position as it is, for example, when the driver does not shift the shift lever 21 and the vehicle speed decreases and there is a concern about engine stoppage. For example, a warning sound is notified to the driver's seat, and the gear is forcibly changed to a gear stage that is in a preferable state.
- the manual transmission mode that is the main part of the present invention will be described.
- the first embodiment is in the manual shift mode (Mmode) and only the jump shift mode 52 is set. Therefore, in FIG. 1, the normal transmission mode 53 and the switching means 55 are not required in the first embodiment.
- the automatic transmission 3 has eight forward speeds in the automatic transmission mode.
- the jump transmission mode 52 is an automatic transmission mode (Amode) with respect to downshifting.
- the number of gears is set to be smaller than the number of gears.
- the downshift of the manual transmission mode jump transmission mode 52 is a combination of 7th speed, 8th speed, 5th speed, 6th speed, 3rd speed and 4th speed in one shift stage, and 2nd speed and 1st speed are independent shifts. Set as a stage. This is because the gear ratio is different, but the map is set so that the gear is a gear such as the fifth forward speed.
- the up-shift is applied to the eighth forward speed step by step as in the normal shift mode.

- the shift lever 21 is down-shifted, specifically, operated once to the “ ⁇ ” position (S1).
- the shift gear position from the current gear stage (shift stage) is determined by the map of the jump shift mode 52 ( S2). For example, if the operation of the shift lever 21 is performed at the eighth speed and the seventh speed in the automatic transmission mode, the sixth speed is selected in any case.
- the gear stage is set from 6th gear to 4th gear according to the jump shift map, and when the driver further operates downshift side once, shifts to 2nd gear. If it is set and operated once more on the downshift side, it is set to the first speed. Therefore, in the full-flight shift mode 52, for example, if manual down is to be performed from the 8th speed to the 1st speed, the operation of the shift lever 21 of 6 speeds ⁇ 4th speed ⁇ 2nd speed ⁇ 1st speed is sufficient. As a result, the driver can quickly perform a downshift operation to a desired gear position. Then, when the shift lever 21 is operated from the M position to the D position, the manual shift mode control, and thus the jump shift mode, is completed.
- the upshift operation is performed by one speed step every time the shift lever 21 is operated to the upshift side once according to the shift step (eight speed forward) of the automatic transmission mechanism.

- the 8th speed, the 7th speed, and the 6th speed may be set to 1 group
- the 3rd speed may be set to 1 group
- the 1st speed may be set to 1 group, and may be set to the 3rd speed stage.
- the downshift is executed from the third speed to the first speed.
- the above-described jump shift mode 52 and the normal one-step normal shift mode 53 are switched by the switching means 55.
- the switching means is switched by a switching switch signal 61 from the manual switching switch 28 by the driver, an accelerator opening speed 62, a road gradient determination 63, and the like.
- the change-over switch 28 may be a dedicated switch for switching between the jump shift mode 52 and the normal shift mode 53, or may be based on the driving orientation of the driver such as a power mode and an economy mode.
- the accelerator release speed (accelerator release speed) is obtained by the accelerator opening by the accelerator opening sensor 25 and the clock means, and when the driver performs a manual downshift operation within a specified time after the accelerator is fully closed, The accelerator opening speed at a time point a predetermined time before the accelerator fully closed is read to calculate the accelerator release speed.
- the driver's intention to decelerate is determined based on whether the driver needs to rapidly decelerate and quickly opens the accelerator, or slowly releases the accelerator without requiring too much deceleration.
- the road gradient determination 63 calculates the running resistance of the vehicle from time to time based on the accelerator opening detected by the accelerator opening sensor 25 and the vehicle speed detected by the output shaft rotation speed (vehicle speed) sensor 27.
- the slope value of the road that is currently running is determined from the running resistance as needed.
- the road gradient determination 63 may determine the road gradient from road information from the navigation or the like. Alternatively, the road gradient may be determined more accurately by combining these.
- the jump gear shift mode is not required, and the normal gear shift mode with one step is sufficient.
- the driver performs a manual downshift operation, if the slope is greater than or equal to a predetermined gradient on the uphill road, the torque is insufficient in the first downshift, and the jump shift mode is required. Further, if the slope is equal to or greater than a predetermined gradient on the downhill road, the engine brake is not sufficient in one-stage downshift, and the jump shift mode is required.
- the shift lever 21 When the shift lever 21 is operated once to the downshift side (S11), if the accelerator release speed (accelerator release speed) 62 is equal to or higher than a predetermined value, that is, if the driver intends a quick deceleration, the jump The transmission mode 52 is selected (S12). If the road gradient is greater than or equal to a predetermined gradient on the uphill side, there is a risk of torque shortage in one-stage deceleration, and the jump transmission mode is selected (S12). If the road gradient is greater than or equal to a predetermined gradient on the downhill side, the engine braking force is not sufficient for one-stage deceleration, and the jump transmission mode is selected (S12).
- the jump shift mode is also selected by the driver's manual operation of the changeover switch (S12).
- Switching of the switching means 55 by the switch signal 61, the accelerator opening speed 62, and the road gradient determination 63 is switched by any one, and is not limited to these signals and determinations, and may be switched by other determinations or the like. Of course.
- step S12 If the jump transmission mode 52 is selected in step S12, the same steps S15 and S16 as in the above-described jump transmission mode flow (S2 and S3 in FIG. 4), for example, when the speed is 7th or 8th, A downshift with a predetermined number of gears is executed such as 4th speed ⁇ 2nd speed ⁇ 1st speed.
- step S12 When the normal shift mode 53 is selected in step S12, a shift (gear) that is one step lower than the current shift (gear) at which the manual downshift is operated is selected (S13), and the selected shift (gear) is selected. Stage) downshift (S14). Thus, the downshift control is completed by one downshift operation of the shift lever 21 (S17).

- the first downshift operation of the shift lever was performed in the jump shift mode
- the second downshift operation that is, the second downshift operation was performed within a relatively short time continuously from the first time.
- it may be configured to switch to the normal transmission mode after the second time. Accordingly, it is possible to prevent a driver who does not know that the jump shift mode is inadvertently entering the jump shift mode and performing a downshift operation excessively suddenly.
- the present invention is applied to an automatic transmission mounted on an automobile, particularly suitable for an automatic transmission having a large number of gears, and is used for an automatic transmission capable of manual shift operation.
