During normal driving, when the driver changes speed from the current reduction ratio to a desired reduction ratio (for example, from 1st to 2nd speed), the electronic control unit uses the negative pressure sensor 6, shift lever position signals 81, 21, and shift knob signal 83 [7 is flow rate control 4
, *@-ji! iunie, 5o1□, 6u8. Yo 1
Shifting is accomplished by releasing and engaging reclutch 130.

22- Table 1 A> Engagement→Release When the driver shifts from 1st speed (1) to 2nd speed (2), he applies his hand to the shift lever mechanism 8 of the automatic clutch transmission and applies force in the pulling direction. In addition, the shift knob signal 83 is as shown in Table 1.
Then, the pull direction is turned OFF as shown in FIG. 5(A), and the electronic control device 1 controls the flow rate control valve 4 and the atmospheric/negative pressure switching valve 5 as shown in FIGS. 5(T) and (G). Therefore, negative pressure is introduced to the negative pressure chamber 221 of the negative pressure servo 2 as follows. By applying current to the flow rate control valve 4 to increase the flow rate of the negative pressure side piping 12a to 112c and turning on the atmospheric/negative pressure switching valve 5, the negative pressure of the intake manifold 11b is increased to connect the negative pressure side piping 12c and the negative pressure side piping 12e. is led to the negative pressure chamber 221 of the negative pressure servo 2. Since a force is applied to the shift lever 10 in the pulling direction, the shift lever position signal 81 becomes OFF as shown in FIG. 5(A) when the shift lever 10 deviates from the first speed position. When the negative pressure servo 2 pulls the diaphragm 212 of the negative pressure servo 2 to the left in the drawing due to the pressure difference between the negative pressure servo 2 and the atmospheric chamber 222, the release rod 191 releases 61111 as shown in FIG. 5(E).
The release rod 191 has a release rod load of 72 kg or more as shown in FIG. 5(1).

At this time, the negative pressure sensor 6 detects the negative pressure chamber 221 of the negative pressure servo 2.
In order to convert the negative pressure level into an electric signal as shown in FIG. 7, a signal shown in FIG. 5 (power) is output to the electronic control device 1.

After performing such an operation, the clutch 130 is released.

5) Release → Engagement When the driver shifts the shift lever 10 to 2nd speed (2), the shift lever position signal 81 turns ON as shown in FIG. Pressure switching valve 5
As shown in FIG. At this time, the negative pressure level of the negative pressure servo 2 is set by the negative pressure sensor 6 in order to correspond to the load of the release rod 1 mo 1 as shown in FIG. 5 (1).
The output of is shown in Figure 5 (force). When the driver releases the shift knob 9, the shift knob signal 83 turns ON as shown in FIG. 5(A). The electronic control device 7 constantly checks the output value of the negative pressure sensor 6, and as shown in FIG. 5 (force), the trend of the output value changes from increasing to decreasing and increases again at point B (point A in FIG. 6). ) is considered the half-clutch point, and the area after that point is determined to be the half-clutch region. The electronic control device 1 reduces the current flowing through the flow control valve 4 as shown in FIG. 5(g), and reduces the stroke speed of the release rod 191 as shown in FIG. 5(e).

In this way, the half-clutch point is detected from the value and tendency of the negative pressure level of the negative pressure servo 2, and the subsequent engagement speed is slowed down, so that the clutch 130 can be adjusted regardless of wear of the clutch 130 or variations between parts. This reduces the shock of engagement and allows for smooth engagement.

26- The speed traces other than 1st speed (2) and 2nd speed (2) operate in the same way.
