[0037] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems are described in detail below with specific embodiments.

[0038] The embodiment of the present application provides a vehicle air conditioning system 100, a structural schematic diagram of the vehicle air conditioning system 100 is as shown in Figure 1 The vehicle air conditioning system 100 comprises a compressor 110, an air intake amount sensor 130 and a controller 120.

[0039] The compressor 110 is used for adjusting an indoor environment temperature.

[0040] The air intake amount sensor 130 is arranged at an air inlet end of the compressor 110, and is used for collecting a current actual air intake amount of the compressor 110.

[0044] In some possible implementation manners, as shown in Figure 1 The vehicle air conditioning system 100 provided in the embodiment of the present application further comprises a temperature sensor 140.

[0045] The temperature sensor 140 is in communication connection with the controller 120, and is used for collecting a real-time indoor environment temperature.

[0046] Based on the same inventive concept, this application provides a vehicle, which includes: a vehicle body, and an in-vehicle air conditioning system 100 as provided in any of the above embodiments.

[0047] The vehicle body has an interior space that can be isolated from the outside world.

[0048] The compressor 110 of the vehicle air conditioning system 100 is fixedly connected to the vehicle body, and the exhaust end of the compressor 110 is connected to the interior space of the vehicle.

[0049] In the vehicle provided in this embodiment, since the controller 120 in the vehicle air conditioning system 100 can execute the vehicle air conditioning control method provided in this application embodiment, the vehicle air conditioning system 100 can improve the accuracy of the compressor 110's air intake, effectively improve the heating and cooling efficiency of the air conditioning, and greatly reduce the probability of accidents such as fires.

[0050] The control methods for vehicle air conditioning described in the above embodiments are detailed below.

[0051] This application provides a method for controlling a vehicle air conditioner, the flowchart of which is shown below. Figure 2 As shown, the method includes at least one control loop, and any control loop includes steps S101-S106:

[0052] S101: Obtain the current initial intake volume control signal and the current variable control signal of the compressor.

[0053] Optionally, the controller 120 acquires the current initial intake volume control signal and the current variable control signal of the compressor 110.

[0054] S102: Determine the current target inhalation volume control signal based on the current initial inhalation volume control signal and the current variable control signal.

[0055] Optionally, the controller 120 determines the current target inhalation volume control signal based on the current initial inhalation volume control signal and the current variable control signal.

[0056] S103: Determine the current ideal intake volume of the compressor based on the current target intake volume control signal.

[0057] Optionally, the controller 120 determines the current ideal intake volume of the compressor 110 based on the current target intake volume control signal.

[0058] S104: Drive the compressor to work according to the current target intake volume control signal, and obtain the current actual intake volume of the compressor.

[0059] Optionally, the controller 120 drives the compressor to work according to the current target intake volume control signal, and the intake volume sensor 130 obtains the current actual intake volume of the compressor 110.

[0060] S105: Determine the difference between the current actual inhalation volume and the current ideal inhalation volume.

[0061] Optionally, the controller 120 determines the current inspiratory volume difference between the current actual inspiratory volume and the current ideal inspiratory volume.

[0062] S106: If the current inhalation volume difference does not fall within the error range, then at least a new variable control signal will be obtained before entering the next control cycle, until the current inhalation volume difference falls within the error range.

[0063] In this embodiment, a vehicle air conditioner control method employs at least one control cycle including the above steps S101-S106, which can improve the accuracy of the compressor 110's intake volume, effectively improve the heating and cooling efficiency of the air conditioner, and greatly reduce the probability of accidents such as fires.

[0064] Specifically, the control method of the vehicle air conditioner obtains the current actual intake volume of the compressor 110 through actual measurement, determines the corresponding current ideal intake volume of the compressor 110 based on the current target intake volume control signal, and then determines whether the current actual intake volume difference between the current actual intake volume and the current ideal intake volume is within the error value range to determine whether the current actual operating condition of the compressor 110 matches the ideal operating condition corresponding to the current target intake volume control signal. If they do not match, the current target intake volume control signal can be adjusted and the aforementioned judgment can be performed again until the current intake volume difference is within the error value range, thereby improving the intake volume accuracy of the compressor 110.

[0065] Moreover, in the control method of the vehicle air conditioner, the current target intake volume control signal is determined by the current initial intake volume control signal and the current variable control signal. That is, the current target intake volume control signal is determined based on the current initial intake volume control signal and the current variable control signal. This can effectively reduce the distortion probability or distortion amplitude of the current target intake volume control signal, thereby improving the intake volume accuracy of the compressor 110.

[0066] Based on the same inventive concept, this application provides another method for controlling a vehicle air conditioner, the flowchart of which is shown below. Figure 3 As shown, the steps include S201-S210 or S201-S209, S211:

[0067] S201: Obtain the current initial intake volume of the compressor.

[0068] Optionally, the current initial intake volume in this step can be obtained in real time by an intake volume sensor located at the intake end of the compressor.

[0069] S202: Determine the current initial inspiratory volume control signal based on the current initial inspiratory volume. Then proceed to step S205.

[0070] Optionally, the current initial inhalation volume control signal P1(t) in this step can be obtained by the controller 120 by looking up the corresponding value in the program parameters based on the obtained current initial inhalation volume.

[0071] S203: Obtain the current ambient temperature inside the vehicle and the current target temperature inside the vehicle, and determine the current temperature difference between the current target temperature inside the vehicle and the current ambient temperature inside the vehicle.

[0072] Optionally, in this step, the current in-vehicle ambient temperature T2(t) can be obtained in real time by a temperature sensor 140 placed inside the vehicle. The current target in-vehicle temperature T1(t) can be set by the driver and passengers through the human-machine interface of the vehicle's air conditioning system. This human-machine interface can be a physical button on the air conditioning unit, an audio command receiver, etc. The current temperature difference ΔT(t) can be calculated by the controller: ΔT(t) = T1(t) - T2(t).

[0073] S204: Determine the current variable control signal based on the current temperature difference.

[0074] Optionally, in this step, determining the current variable control signal based on the current temperature difference may include: determining the proportional correction factor Kf and the integral correction factor Kp using a PID (Proportion Integral Differential) algorithm and empirical formulas; and determining the current variable control signal P(t) using a PID algorithm based on the current temperature difference ΔT(t), the proportional correction factor Kf, and the integral correction factor Kp. Specifically, and -1 <P<1。

[0075] S205: Obtain the current initial intake volume control signal P1(t) and the current variable control signal P(t) of the compressor.

[0076] S206: Determine the current target inspiratory volume control signal based on the current initial inspiratory volume control signal and the current variable control signal.

[0077] Optionally, in this step, the current target inhalation volume control signal Pi(t) can be the sum of the current initial inhalation volume control signal and the current variable control signal, i.e., Pi(t) = P1(t) + P(t).

[0078] S207: Determine the current ideal intake volume of the compressor based on the current target intake volume control signal.

[0079] Optionally, in this step, the controller 120 can find the current ideal intake volume S1(t) of the compressor 110 in the program parameters according to the current target intake volume control signal Pi(t).

[0080] S208: Drive the compressor to work according to the current target intake volume control signal, and obtain the current actual intake volume of the compressor.

[0081] Optionally, in this step, the controller 120 drives the compressor 110 to work with the current target intake volume control signal. At the same time, the intake volume sensor 130 located at the intake end of the compressor 110 collects the current actual intake volume S(t) of the compressor 110 in real time.

[0082] S209: Determine the difference between the current actual inspiratory volume and the current ideal inspiratory volume. Then proceed to step S210, or step S211.

[0083] In this step, the current inhalation volume difference Es(t) can be obtained by the controller 120 based on the difference between the current actual inhalation volume and the current ideal inhalation volume, that is, Es(t) = S1(t) - S(t).

[0084] S210: If the current intake volume difference Es(t) does not belong to the error value interval Q, then drive the compressor to work with the current initial intake volume control signal P1(t), issue a warning signal, and enter the next control cycle after at least acquiring a new variable control signal, until the current intake volume difference belongs to the error value interval.

[0085] S211: If the current intake volume difference Es(t) belongs to the preset error value range Q, then the compressor will continue to be driven by the current target intake volume control signal Pi(t).

[0086] In this embodiment, another vehicle air conditioning control method employs at least one control cycle including the above steps, including steps S201-S210 or S201-S209, S211, which can improve the accuracy of the compressor 110's intake volume, effectively improve the heating and cooling efficiency of the air conditioner, and greatly reduce the probability of accidents such as fires.

[0087] The specific implementation principle is the same as the vehicle air conditioning control method provided in the above embodiment, the difference being that: the current initial intake volume in step S201 can be obtained in real time by the intake volume sensor 130 installed at the intake end of the compressor 110; the current initial intake volume control signal in step S202 can be obtained by the controller 120 by looking up the corresponding value in the program parameters based on the obtained current initial intake volume. This can effectively reduce the distortion probability or distortion amplitude of the current target intake volume control signal, thereby improving the intake volume accuracy of the compressor 110.

[0088] The difference lies in the fact that the current variable control signal is obtained through steps S203 and S204. Specifically, the current variable control signal is determined based on the temperature difference between the current ambient temperature inside the vehicle, which is collected in real-time by the temperature sensor 140 located inside the vehicle, and the current target temperature inside the vehicle, set by the occupants through the vehicle's air conditioning human-machine interface. This results in a more accurate current variable control signal determined based on the ambient temperature and the set temperature, leading to greater comfort for the occupants.

[0089] Based on the same inventive concept, this application provides a vehicle air conditioning control device 200, the structural framework of which is shown in the schematic diagram below. Figure 4 As shown, it includes: a compressor suction volume acquisition module 210 and a control module 220.

[0090] The compressor suction volume acquisition module 210 is used to acquire the current actual suction volume of the compressor.

[0091] The control module 220 is used to acquire the current initial suction volume control signal and the current variable control signal of the compressor; determine the current target suction volume control signal based on the current initial suction volume control signal and the current variable control signal; drive the compressor to work according to the current target suction volume control signal; determine the current suction volume difference between the current actual suction volume and the current ideal suction volume; if the current suction volume difference does not belong to the preset error value range, stop driving the compressor to work with the current target suction volume control signal, and enter the next control cycle after acquiring at least a new variable control signal; if the current suction volume difference belongs to the preset error value range, continue driving the compressor to work with the current target suction volume control signal.

[0092] The vehicle air conditioning control device in this embodiment can execute any of the vehicle air conditioning control methods provided in this application embodiment. Their implementation principles are similar and will not be described in detail here.

[0093] In some possible implementations, such as Figure 4 As shown, the vehicle air conditioning control device 200 also includes a temperature acquisition module 230.

[0094] The temperature acquisition module 230 is used to acquire the current ambient temperature inside the vehicle and the current target temperature inside the vehicle.

[0095] The compressor suction volume acquisition module 210 is also used to acquire the current initial suction volume of the compressor.

[0096] The control module 220 is also used to determine the current initial intake volume control signal based on the current initial intake volume; and to determine the current temperature difference between the current target temperature inside the vehicle and the current ambient temperature inside the vehicle; and to determine the current variable control signal based on the current temperature difference.

[0097] Based on the same inventive concept, embodiments of this application provide a computer-readable storage medium storing a computer program, which, when executed by an electronic device, implements the vehicle air conditioning control method provided in any of the foregoing embodiments.

[0098] The computer-readable storage media provided in this embodiment include, but are not limited to, any type of disk (including floppy disk, hard disk, optical disk, CD-ROM, and magneto-optical disk), ROM, RAM, EPROM (Erasable Programmable Read-Only Memory), EEPROM, flash memory, magnetic cards, or optical cards.

[0100] By applying the embodiments of this application, at least the following beneficial effects can be achieved:

[0101] 1. The actual current intake volume of the compressor is obtained through actual measurement. Based on the current target intake volume control signal, the corresponding current ideal intake volume of the compressor is determined. Then, by judging whether the difference between the current actual intake volume and the current ideal intake volume is within the error range, it is determined whether the current actual operating condition of the compressor matches the ideal operating condition corresponding to the current target intake volume control signal. If they do not match, the current target intake volume control signal can be adjusted and the above judgment can be performed again until the difference between the current intake volumes is within the error range, thereby improving the intake volume accuracy of the compressor.

[0102] 2. The current target intake volume control signal is determined by the current initial intake volume control signal and the current variable control signal. That is, the current target intake volume control signal is determined based on the current initial intake volume control signal and the current variable control signal. This can effectively reduce the distortion probability or distortion amplitude of the current target intake volume control signal, thereby improving the intake volume accuracy of the compressor.

[0103] 3. The current initial intake volume can be acquired in real time by an intake volume sensor located at the compressor's intake end; the current initial intake volume control signal can be obtained by the controller by looking up the corresponding value in the program parameters based on the acquired current initial intake volume. This can effectively reduce the probability or amplitude of distortion in the current target intake volume control signal, thereby improving the compressor's intake volume accuracy.

[0104] 4. The current variable control signal is determined based on the temperature difference between the current ambient temperature inside the vehicle, which is collected in real time by a temperature sensor placed inside the vehicle, and the current target temperature inside the vehicle, which is set by the driver and passengers through the human-machine interface of the vehicle's air conditioning system. In this way, the current variable control signal determined based on the ambient temperature and the set temperature is more accurate, and the driver and passengers inside the vehicle will be more comfortable.

[0105] 5. Improving the accuracy of the compressor's air intake can effectively improve the heating and cooling efficiency of the air conditioner and greatly reduce the probability of accidents such as fires.
