が知られている。2. Description of the Related Art As a conventional automotive air conditioner, for example, an air conditioner using an oscillating variable displacement compressor is known. In this type of oscillating variable displacement compressor, a pressure control valve is disposed between a communication passage between a crank chamber in which an oscillating plate is accommodated and a suction chamber, and the pressure in the crank chamber is adjusted by the pressure control valve. Thus, the tilt angle of the rocking plate is changed, whereby the piston stroke is changed, and the discharge capacity is controlled. Here, the swing type variable displacement compressor has an external variable type in which the pressure control valve is operated by an external signal and an internal variable type in which the suction pressure is automatically controlled to a predetermined characteristic substantially by the pressure balance in the compressor. The type is known.

【発明が解決しようとする課題】前述した揺動式可変容

揺動板の傾斜角が吐出容量増加側に変化し，その結果，
吸入圧力が低下して異常振動が発生し，吐出容量の制御
が不能になり，圧縮機が破損に至る虞がある。In an automotive air conditioner using an oscillating variable displacement compressor as described above, for example, when the compressor rotation speed enters a high rotation range under a high heat load condition, the rotation of the compressor does not increase. As the moment due to the balance increases, the tilt angle of the oscillating plate changes to the side where the discharge capacity increases, and as a result,
Abnormal vibration occurs due to a decrease in the suction pressure, the control of the discharge capacity becomes impossible, and the compressor may be damaged.

方がより高い回転数まで安定な制御が可能となる。FIG. 8 is a diagram showing an abnormal vibration generation region at a rotation speed of a conventional oscillating variable displacement compressor. As shown in FIG. 8, the rotation speed at which abnormal vibration occurs varies depending on the discharge pressure, and the lower the discharge pressure, that is, the smaller the cooling load, the more stable the control to the higher rotation speed.

る。FIG. 9 is a diagram showing the relationship between the amount of air blown to an evaporator of a refrigerating circuit including a conventional oscillating variable capacity compressor and the discharge pressure of the compressor. As shown in FIG. 9, as a means for changing the cooling load, it is advantageous to change the amount of air blown to the evaporator of the refrigeration circuit. As the amount of air blows smaller, the discharge amount decreases, and the discharge pressure also increases. Lower accordingly.

る欠点がある。Here, as a countermeasure against the above-mentioned abnormal vibration, there has been known a method in which the discharge capacity of a compressor is reduced by an external signal (Japanese Patent Laid-Open No. 3-986).
A so-called internal variable type variable displacement compressor cannot control the discharge capacity from the outside, and cannot cope with the above problem. Also,
As another measure against abnormal vibration, it has been proposed to stop the operation of the compressor, but in this case, there is a disadvantage that air conditioning in the vehicle compartment is sacrificed.

リシス（α）を設けている。Next, at step 12, a comparison is made between the applied voltage Vc and the reference voltage Vs. In the comparison judgment, as shown in FIG. 3, if the reference voltage Vs is larger than the reference voltage Vs, the output is ON, and if it is smaller than the reference voltage Vs, the output is OFF.

れば制御動作を終了する。If the output is ON in step 12, the process proceeds to step 13, where the rotational speed judging means compares the rotational speed Ne from the rotational speed detecting means 1 with the reference rotational speed Ns. As shown in FIG. 4, the comparison judgment is an ON output if the rotation speed Ne is higher than the reference rotation speed Ns, and an OFF output if the rotation speed Ne is smaller than the reference rotation speed Ns. However, a hysteresis (β) is provided to stabilize the judgment. Further, it is turned on in step 13.
When the output is obtained, it is determined that the vehicle is in the abnormal vibration generation area. Therefore, in step 14, the blower application voltage is limited to Vs and output. As a result, the discharge pressure is reduced, and it is possible to escape from the abnormal vibration generation area. Step 12
Alternatively, if the output is OFF at step 13, it is determined that the output is outside the abnormal vibration occurrence area.
The calculated value Vc is output as it is as the blower applied voltage. If the blower is not turned off in step 16, the process returns to step 11, and the above operation is repeated. If the blower is turned off, the control operation ends.

The difference from the operation of the control device of FIG. 2 is that the applied voltage determination step of step 12 in FIG. A step of comparing and judging the discharge pressure (step 23) is added to the step of judging. As shown in FIG. 7, in step 23, if the discharge pressure Pd is higher than the reference pressure Pds, the output becomes ON, and if the discharge pressure Pd is lower, the output becomes OFF. However, hysteresis (γ) is provided for stabilizing the determination.

If both steps 24 and 24 are determined to be ON, it is determined that the vehicle is in the abnormal vibration occurrence area.
In step 5, the blower applied voltage is limited to Vs and output. As a result, the discharge pressure is reduced, and it is possible to escape from the abnormal vibration generation area. If any of steps 22, 23 and 24 is determined to be OFF,
Since it is determined that it is outside the abnormal vibration occurrence region, the calculated value Vc is output as it is as the blower applied voltage in step 26.
