Description
Technical Field
The invention relates to the technical field of automobile air conditioners, in particular to a control method of an automobile air conditioner compressor.
Background
With the development of the automobile industry, the high-efficiency air conditioner gradually adopts a variable displacement compressor, and for the variable displacement compressor, no matter an internal control variable displacement form or an external control variable displacement form, for the control of the displacement of the compressor, the angle of a swash plate in the compressor is mainly controlled by the change of suction pressure and exhaust pressure, so that the stroke and the displacement of the compressor are controlled.
In addition to the influence of the variation of the air suction pressure and the air discharge pressure of the compressor, the heat dissipation of the condenser is also an important factor influencing the air discharge of the compressor, and during the running of the automobile, the working state of a heat dissipation fan (namely the heat dissipation and air suction quantity of the condenser), the running speed of the automobile (namely the heat dissipation and air inlet quantity of the condenser), the environment temperature of the automobile (namely the heat dissipation and air inlet temperature of the condenser) and the like all influence the compressor through the condenser.
In addition, for air conditioning compressors that use an externally controlled variable displacement version, the air conditioning controller adjusts the compressor displacement according to its own internal algorithm by adjusting the current to a displacement adjustment solenoid valve located between suction and discharge within the compressor cavity. The displacement of the compressor is different, so that the engine torque required by the compressor is different, the air conditioner controller calculates the torque requirement and sends the calculated torque requirement to the engine ECM, and the engine ECM carries out torque compensation on the compressor according to the received torque requirement and the speed ratio between the engine and the compressor, so that the normal work of the compressor is realized. When the heat load of the air conditioner is small or the temperature in the carriage is balanced, the displacement demand of the compressor is reduced, the torque demand is also reduced, and the engine ECM can adjust the fuel injection quantity to achieve the aim of saving fuel for the engine.
At present, although the existing air conditioner compressor in the external control variable displacement mode can realize the service function which the air conditioner compressor should have, the practical application still has some defects. For example, since the compressor is not used for a long time, corrosion of a clutch of the compressor and reduction of the sealing performance of a main shaft of the compressor are likely to occur. When the voltage of the whole vehicle exceeds the voltage range of the control valve of the external control variable displacement compressor, the displacement adjustment of the compressor is easy to be out of control, and when the rotating speed of the engine is higher, the compressor can work at full displacement, and the service life of the compressor can be influenced. In addition, for the PID control of the displacement adjustment of the compressor, the influence of the vehicle speed, the ambient temperature and the like on the exhaust pressure is not considered, the displacement adjustment is easy to be distorted, and the expected displacement adjustment effect is difficult to achieve. In addition, the fluctuation of the engine speed is easily caused in the opening and closing process of the compressor, and the running stability of the engine is influenced.

When the control current of the displacement regulating electromagnetic valve is low, the preset current threshold value is adopted to obtain the torque compensation value of the compressor, so that the impact on the engine torque when the compressor works can be avoided.

In the control method of the embodiment, as one aspect thereof, the control method comprises the step of controlling the compressor to be started when the compressor is not used for a long time, so as to avoid corrosion of a clutch of the compressor caused by the long-time non-use of the compressor and reduction of tightness of a main shaft of the compressor, and the service life of the compressor is prolonged.
At this time, in combination with the method shown in fig. 1, the control method of the present embodiment includes that when the compressor is not started in n consecutive engine ignition cycles, and the current compressor is in a stopped state, the engine is running, and the engine has run for a first preset time threshold, and the rotation speed q of the currently running engine exceeds the first preset rotation speed threshold, the air-conditioning controller controls the compressor to start, and makes the compressor run for a second preset time threshold.
In the above control method, specifically, the engine is turned off from on to off as an ignition cycle of the engine, and in the implementation, the number n of ignition cycles of the engine is selected to be a value greater than or equal to 1 according to design requirements and the like. In addition, the first predetermined time threshold may be, for example, 5min, the first predetermined rotational speed threshold may be, for example, 2000r, and the second predetermined time threshold may be generally set to 5 s. Meanwhile, the air conditioner controller can control the starting of the compressor by adopting the existing control strategy.
In addition to the above control of the compressor being not used for a long time, as another aspect of the control method of the present embodiment, the method further includes cutting off the control current of the displacement regulating solenoid valve in the compressor, that is, regulating the control current to 0A, and turning off the compressor when the vehicle voltage of the vehicle exceeds a preset voltage threshold interval. And when the voltage of the whole vehicle is abnormally disappeared, the control on the displacement adjusting electromagnetic valve can be restored.
At this time, the preset voltage threshold interval may be generally set to 8.5V to 16.5V, and in this embodiment, the compressor is also protected by turning off the compressor when the voltage of the entire vehicle exceeds the preset voltage threshold interval, so as to avoid damage caused by abnormal voltage of the entire vehicle.
In addition, as another aspect of the control method of this embodiment, the control method further includes adopting a rotation speed protection strategy for the compressor, and is combined with that shown in fig. 2, which is specifically:

(2) When the rotating speed q of the engine meets a second preset rotating speed threshold value which is more than q and less than or equal to a third preset rotating speed threshold value, the air conditioner controller controls the upper limit value i of the control current of the displacement adjusting electromagnetic valveLimit ofSatisfy iLimit of═ [ (second preset rotation speed threshold-first preset current threshold)/(third preset rotation speed threshold-second preset rotation speed threshold)]Q, wherein the second preset rotational speed threshold is less than the first preset current threshold.
(3) When the rotating speed q of the engine meets a third preset rotating speed threshold value which is less than or equal to a fourth preset rotating speed threshold value, the air conditioner controller controls the upper limit value i of the control current of the displacement adjusting electromagnetic valveLimit ofIs the second predetermined current threshold.
(4) And when the rotating speed q of the engine meets q which is larger than a fourth preset rotating speed threshold value, the air conditioner controller controls the compressor to be closed.
In the above control method, the second preset rotation speed threshold, the third preset rotation speed threshold and the fourth preset rotation speed threshold may be generally set to 3660r, 4882r and 5500r, respectively, and the first preset rotation speed threshold and the second preset current threshold may be set to 0.8A and 0.5A, respectively.
It should be noted that when the engine speed q is greater than 5500r and the engine speed q is decreased to 4500r, the compressor can be controlled to be turned on again, and the upper limit value i of the control current of the displacement regulating solenoid valve can be controlled according to the methodLimit ofAnd controlling.
Meanwhile, in the embodiment, the upper limit value of the control current of the displacement regulating electromagnetic valve of the compressor is set when the engine speeds are different, and the compressor is closed when the engine speed exceeds a certain value, so that the rotation speed protection of the compressor can be realized, and the compressor is prevented from being damaged.
Further, as another aspect of the control method of the present embodiment, the control methodThe method further comprises the step that when the air conditioner controller calculates the control current i of the displacement regulating electromagnetic valve in the compressor, the control current i of the displacement regulating electromagnetic valve is also equal to iComputing+iRevisionWherein i isComputingAdjusting the control current i of the electromagnetic valve for the air conditioner controller according to the calculated displacement of the air conditionerRevisionA preset control current revision value, and iRevisionGreater than 0.
Through making the control current of displacement control solenoid valve increase revision value, this embodiment also just can reduce the speed of a motor vehicle, ambient temperature to the carminative influence of compressor, and then can avoid causing the big discharge capacity of compressor demand, the problem of actual little discharge capacity to can make the discharge capacity grow of compressor, and be favorable to improving the cooling effect in the carriage when air conditioner refrigeration.
In addition, as another aspect of the control method of the embodiment, the control method further includes a strategy for controlling the on and off of the compressor, and specifically, when the compressor needs to be turned on, first, the rotation speed q of the engine needs to be greater than a fifth preset rotation speed threshold, and the fifth preset rotation speed threshold may be generally set to 500 r.
Further, after the compressor is started, the compressor needs the engine to perform torque compensation to drive the compressor to operate reliably, and at this time, the calculation of the torque compensation value needed by the compressor includes a process that a control current i from the start of the compressor to the displacement regulating electromagnetic valve in the compressor reaches a third preset current threshold. The air conditioner controller obtains a torque compensation value of the compressor according to a preset fourth preset current threshold value, the rotating speed of the compressor and the exhaust pressure.
In this case, the third preset current threshold may be set to be 0.26A, the fourth preset current threshold may be set to be 0.3A, and the torque compensation value of the compressor is obtained by using the fourth preset current threshold, the rotation speed of the compressor and the discharge pressure, specifically, by using a table look-up. The lookup table corresponding to the torque compensation value of the compressor and the fourth preset current threshold, the rotating speed of the compressor and the exhaust pressure of the compressor is generally the same as the conventional acquisition mode, namely, the lookup table is obtained by setting a plurality of parameter values in the design process of the whole vehicle, and fitting after testing, and the obtained lookup table is stored in the compressor controller for query.
After the torque compensation value of the compressor is obtained, the air conditioner controller may multiply the obtained torque compensation value by a speed ratio, which is a ratio between a rotation speed q of the engine and a rotation speed of the compressor, and then send the multiplied torque compensation value to the engine. Therefore, the engine can carry out torque compensation on the compressor according to the obtained torque compensation value.
In this embodiment, when the control current i of the displacement adjustment solenoid valve is greater than a third preset current threshold, the air conditioner controller obtains a torque compensation value of the compressor according to the current control current i of the displacement adjustment solenoid valve, and the rotating speed and the exhaust pressure of the compressor. In this case, the torque compensation value of the compressor is also obtained by looking up a table, and after the torque compensation value of the compressor is obtained, the air conditioner controller multiplies the obtained torque compensation value by a speed ratio and sends the multiplied value to the engine.
In the embodiment, when the control current of the displacement regulating electromagnetic valve is low, the preset current threshold value is adopted to obtain the torque compensation value of the compressor, so that the impact on the torque of the engine during the operation of the compressor can be avoided, and after the control current exceeds the third preset current threshold value, the torque compensation value is obtained according to the actual control current, so that the torque compensation provided by the engine can meet the working requirement of the compressor, and the working efficiency of the compressor can be ensured.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
