In the test equipment, the rotational speed of the specimen with an automatic transmission function is controlled at a constant level, and the load torque on the output shaft side of the specimen is controlled at a constant level, so that the ll:l:rii4 vehicle of the specimen is uniformly controlled.

供試体１を回転させるために、車速設５１１器８で設定

御信号Ｎ４は偏差信号Ｎ３が増幅されてＡ・（Ｎ２
Ｎｌ） となり、定常運転時には速度信号Ｎ１が速度
制御信号Ｎ４の値に一致しＮ４−Ｎ。At the time of starting, the speed signal N1 is not given to the subtracter 7 because the specimen 1 is not rotating. Therefore, the deviation signal N3 given from the subtracter 7 to the PI amplifier 9 is the vehicle speed signal N2.
and is amplified by the PI amplifier 9. Next, this amplified speed control signal N4 is given to the speed control circuit 10. At this time, there is no feedback signal from the first speed detector 3, and only the speed control signal N4 is given to the speed control circuit 0, and the tail #1 machine 2 starts rotating due to the output of the speed control circuit 10. Then, the specimen 1 also begins to rotate, and the second speed detector 5 detects a speed increase of +3 proportional to the rotational speed of the output shaft 1b.
Nl is emitted. Furthermore, this causes the deviation signal N
3 is the difference between the vehicle speed signal N2 and the speed signal Nl and is applied to the PI intensifier 9. Then, the deviation signal N3 is determined by the response speed of the integrating circuit included in the PI amplifier 91.
is amplified, and when the speed signal N substantially matches the value of the speed control signal N4, the rotation of the output shaft 11 enters a steady state of operation. That is, if the amplification degree of the PI amplifier 9 is A, and the gear ratio between the input shaft 1a and the output r+Hb of the specimen 1 is 1=1, the deviation signal N3 given to the PIQ amplifier 9 is (N
2 Nl) Sanaru. Further, the speed control signal N4 from the PI amplifier 9 is amplified by the deviation signal N3 and becomes A.(N2
Nl), and during steady operation, the speed signal N1 matches the value of the speed control signal N4, resulting in N4-N.

の一巡伝達特性は変わらない。Note that this favorable speed signal Nl is slightly lower than the vehicle speed signal N2. This means that if the amplification degree A is made infinitely large from the closed-loop gain characteristics of the PI amplifier 9, the speed control signal N4, that is, the speed signal N, will match the value of the vehicle speed signal N2 set in the PI amplifier 9. It takes a very long time for this coincidence to occur, which is caused by the fact that the response time is somewhat fixed from the input value of the deviation signal N3 by the integrating circuit included in the P1 amplifier 9. Therefore, in order to obtain the desired vehicle speed, the value of the speed signal N1 is adjusted by the vehicle speed setter 8 without looking at the value of the speed signal N1. Also, at this time, the deviation signal N
3, the rotation of the output shaft 1b changes A, but the loop transfer characteristic of the control system does not change.

一回転となる。For example, the tooth TJj ratio between the input shaft 1a and the output Hib is 1:
1 to 1: μI is changed from 1 to 1. At the first moment, the speed signal N1 decreases to approximately becomes larger, and as a result, speed control No. 43 N4 becomes larger than before the gear ratio change, increasing the rotational speed of drive mode 2 to F!+
It increases. Then, the speed signal Nl gradually increases, and when it approaches the maximum value of the speed control signal N4, the rotation of the output shaft 1b ceases to operate at a steady state. That is, II'I amplifier 9i
Here, (N2 Nl) is given as the deviation signal N3. Furthermore, the speed control signal N4 from the PI amplifier 9 is A·(N
2 Nl) Table f, f, gear ratio is 1:16 to 2N4
=N17 Then the speed signal N1 during steady operation is A-Nz
/(A+2). Further, since the vehicle speed signal N2 remains unchanged, the rotational speed of the input shaft 1a side of the specimen J increases, but the rotational speed of the output shaft Ib side of the specimen 1 remains almost the same as before the gear ratio was changed.

When the speed signal N remains unchanged and the speed is less than speed 1f (17, which is almost equal to the value of the control signal N4), steady operation occurs.
