[0040] With the development of vehicle technology, more and more users are installing parking air conditioners on their cars to make up for the defects of the original car air conditioners during use. However, whether it is the original car air conditioner or the parking air conditioner, the user needs to manually operate it according to his or her own temperature feeling to turn it on or off, which increases the complexity of user operation and cannot meet the current user's demand for intelligent operation.

[0041] In addition, the use of car refrigerators is becoming more and more popular. The use of car refrigerators makes the parking air conditioner, car refrigerator and original car air conditioner form the refrigeration system of the whole car. The three are independent electrical appliances, which are currently installed separately according to the needs of the car owner without interconnection logic. The present invention hopes to connect the refrigeration system of the whole car to the CAN (Controller Area Network) protocol of the vehicle through a set of refrigerant circulation system and electronic control logic to achieve connection operation and realize integrated control, giving the car owner a better experience.

[0042] Based on the above ideas, an embodiment of the present invention provides a vehicle refrigeration system control method, wherein the vehicle includes a power source; the refrigeration system includes: an original vehicle air conditioner and a parking air conditioner. Figure 2 As shown, the vehicle refrigeration system control method described in this embodiment includes step S101 and step S102. The specific contents of these steps are described in detail below:

[0043] Step S101, when receiving predetermined information, obtaining current state information of the power source and current cabin temperature of the vehicle;

[0044] In this embodiment, the predetermined information may be: information that the user / owner has opened the door, information that there is someone in the car / cabin, information that the person in the car / cabin is the owner or a predetermined user, etc. The power source may be a device such as an engine or an electric motor that provides power to the vehicle. The current state information of the power source may include: information that the power source is in a started state, information that the power source is in a shut-down state, etc.

[0045] Specifically, when the system detects that the user opens the car door, it automatically obtains the current status information of the power source and the current cabin temperature; or, when the system detects that there is someone in the cabin, it automatically obtains the current status information of the power source and the current cabin temperature; or, when the system detects that there is someone in the cabin and that person is the car owner or the intended user, it automatically obtains the current status information of the power source and the current cabin temperature, thereby providing a data basis for the subsequent control of the start and stop of the original vehicle air conditioner and / or the parking air conditioner.

[0046] Step S102, based on the current state information of the power source and the current cabin temperature, controlling the start and stop of the original vehicle air conditioner and / or the parking air conditioner.

[0047] In this embodiment, the original vehicle air conditioner refers to the air conditioning system that comes with the vehicle when it leaves the factory, and it is powered by the power source of the vehicle. For example, for a vehicle using an engine, the original vehicle air conditioner is powered by the operation of the engine; for a vehicle using an electric motor, the original vehicle air conditioner is powered directly by the electric motor. The parking air conditioner refers to the air conditioning system installed by the user on the vehicle, and it is powered by the battery of the vehicle.

[0048] As described above, the current state information of the power source includes: information that the power source is in the startup state. In order to more accurately control the start and stop of the original vehicle air conditioner and / or the parking air conditioner to meet the actual needs of users, the control of the start and stop of the original vehicle air conditioner and / or the parking air conditioner based on the current state information of the power source and the current cabin temperature described in this embodiment includes: when the power source is in the startup state, based on the comparison result of the current cabin temperature with the first preset temperature, selectively executing the first control mode or the second control mode or the third control mode; wherein, the first control mode includes: controlling both the original vehicle air conditioner and the parking air conditioner to be turned on; the second control mode includes: controlling the original vehicle air conditioner to be turned on and the parking air conditioner to be turned off; the third control mode includes: controlling both the original vehicle air conditioner and the parking air conditioner to be turned off.

[0049] Furthermore, in one embodiment, in order to further accurately control the start and stop of the original vehicle air conditioner and / or the parking air conditioner, the first preset temperature described in this embodiment includes a temperature upper limit value and a temperature lower limit value. Under this premise, the selective execution of the first control mode, the second control mode, or the third control mode based on the comparison result between the current cabin temperature and the first preset temperature described in this embodiment includes: when the current cabin temperature is greater than or equal to the temperature upper limit value, the first control mode is executed; when the current cabin temperature is less than the temperature upper limit value and greater than the temperature lower limit value, the second control mode is executed; when the current cabin temperature is less than or equal to the temperature lower limit value, the third control mode is executed.

[0050] That is, in this embodiment, under the premise that the system receives any of the predetermined information described above and the power source is in the starting state, when the current cabin temperature is greater than or equal to the upper temperature limit, the original vehicle air conditioner and the parking air conditioner are both controlled to be turned on; when the current cabin temperature is less than the upper temperature limit and greater than the lower temperature limit, the original vehicle air conditioner is controlled to be turned on and the parking air conditioner is controlled to be turned off; when the current cabin temperature is less than or equal to the lower temperature limit, the original vehicle air conditioner and the parking air conditioner are both controlled to be turned off.

[0051] In one embodiment, the temperature upper limit is set to 35°C, the temperature lower limit is set to 24°C; the power source is the engine; the predetermined information is the status information of someone in the cabin. Then, when the system detects that there is someone in the cabin and the engine is in the starting state, regardless of whether the vehicle is in the driving state at this time, the system will automatically detect the current cabin temperature. When the current cabin temperature is greater than or equal to 35°C, it indicates that the cabin temperature is very high at this time, and the user / owner will feel very hot. At this time, the system will automatically turn on the original car air conditioner and the parking air conditioner to quickly cool down the cabin; when the current cabin temperature is less than 35°C and greater than 24°C, it indicates that the cabin temperature is slightly high at this time, and only one air conditioner needs to be turned on to cool down. In order to reduce the impact of the battery voltage fluctuation on the parking air conditioner, the original car air conditioner is used to cool down, that is, the original car air conditioner is turned on and the parking air conditioner is turned off at this time; when the current cabin temperature is less than or equal to 24°C, it indicates that the cabin temperature is low at this time, and the user / owner will feel cooler. At this time, the system will automatically turn off the original car air conditioner and the parking air conditioner to make the user feel more comfortable.

[0052] Of course, the above-mentioned temperature upper limit value and temperature lower limit value may also be set to other temperature values ​​according to actual needs, and this embodiment does not impose any specific limitation on this.

[0053] As described above, the current state information of the power source described in this embodiment also includes: information that the power source is in the off state. In order to more accurately control the start and stop of the original vehicle air conditioner and / or the parking air conditioner to meet the actual needs of the user, the current state information of the power source and the current cabin temperature described in this embodiment control the start and stop of the original vehicle air conditioner and / or the parking air conditioner, including: when the power source is in the off state, judging the magnitude relationship between the current cabin temperature and the second preset temperature; when the current cabin temperature is greater than or equal to the second preset temperature, controlling the parking air conditioner to turn on; when the current cabin temperature is less than the second preset temperature, controlling the parking air conditioner to turn off.

[0054] In this embodiment, since the operation of the original vehicle air conditioner requires the drive of a power source, when the power source is in an off state, the original vehicle air conditioner will automatically stop running. At this time, the system can only control the opening and closing of the parking air conditioner.

[0055] That is, in this embodiment, when the system receives any of the predetermined information described above and the power source is in the off state, when the current cabin temperature is greater than or equal to the second preset temperature, the parking air conditioner is controlled to turn on; when the current cabin temperature is lower than the second preset temperature, the parking air conditioner is controlled to turn off.

[0056] In one embodiment, the second preset temperature is set to 30°C, the power source is the engine, and the predetermined information is the status information of someone in the cabin. Then, when the system detects that there is someone in the cabin and the engine is in the off state, the system will automatically detect the current cabin temperature. When the current cabin temperature is greater than or equal to 30°C, it indicates that the cabin temperature is high at this time, and the user / owner will feel hot. At this time, the system will automatically turn on the parking air conditioner to cool down. In this process, once the system detects that the current cabin temperature is less than 30°C, it will automatically turn off the parking air conditioner to keep the cabin temperature at a comfortable state for the user.

[0057] Furthermore, in one embodiment, the refrigeration system further includes: a vehicle refrigerator; the vehicle refrigerator includes a refrigerator body. In order to automatically control the opening and closing of the vehicle refrigerator and further improve the user experience, the method described in this embodiment further includes: obtaining the placement information in the refrigerator body; and controlling the opening and closing of the vehicle refrigerator based on the placement information.

[0058] Furthermore, in one embodiment, in order to more accurately control the opening and closing of the vehicle refrigerator and better meet the actual needs of users, the placement information described in this embodiment includes: whether there are items placed in the refrigerator box. Under this premise, the control of the opening and closing of the vehicle refrigerator based on the placement information described in this embodiment includes: when there are items placed in the refrigerator box, controlling the vehicle refrigerator to start running; when there are no items placed in the refrigerator box, controlling the vehicle refrigerator to stop running.

[0059] Specifically, a gravity sensor is installed in the refrigerator body, and the gravity sensor is used to detect whether there are items placed in the refrigerator body. When it is detected that there are items placed in the refrigerator body, a signal "1" is output to the system; when it is detected that there are no items placed in the refrigerator body, a signal "2" is output to the system. When the system receives the signal "1", the vehicle refrigerator is controlled to open, that is, the vehicle refrigerator is controlled to start cooling, thereby realizing the refrigeration function of the items; when the system receives the signal "2", the vehicle refrigerator is controlled to close, that is, the vehicle refrigerator is controlled to stop cooling, thereby realizing the function of automatically opening and closing the vehicle refrigerator according to user needs.

[0060] Figure 4 The following is a schematic diagram of the control logic of the original vehicle air conditioner, the parking air conditioner and the vehicle refrigerator according to an embodiment of the present invention. It should be noted that the figure only shows part of the control logic, but does not list all the control logic. Figure 4In order to make the diagram more concise, some technical terms are abbreviated. Among them, "electromagnetic" refers to the electromagnetic clutch, "electromagnetic open" refers to the electromagnetic clutch opening / power on, and "electromagnetic close" refers to the electromagnetic clutch closing / power off. "External unit" refers to the external compressor, that is, the compressor shared by the car refrigerator and the parking air conditioner, and "external unit stop" means that the external compressor stops running.

[0061] Specifically, as mentioned above, a gravity sensor is installed in the refrigerator to detect whether there are items in the refrigerator. When there are items, the signal is "1", and when there are no items, the signal is "2". By default, the refrigerator starts to refrigerate when there are items, thereby realizing the refrigeration function of the items, and the refrigerator stops refrigerating when there are no items. A temperature sensor is installed in the vehicle's cab to detect the cabin temperature in real time; a speed sensor is installed on the engine crankshaft to detect whether the engine is in the starting state. When the owner enters the cab and starts the engine, the temperature sensor in the cab / cabin monitors the temperature. Let the current cabin temperature be T, the upper temperature limit be T0, and the lower temperature limit be T1. When T≥T0, the signal is A, and both the original car air conditioner and the parking air conditioner are turned on to achieve rapid cooling; when T1<T<T0, the signal is B, and the speed sensor detects the engine crankshaft speed. If the engine crankshaft speed>0, the signal is α, and the original car air conditioner is controlled to run. In order to reduce the impact of battery voltage fluctuations on the parking air conditioner, the parking air conditioner is turned off at this time, and only the original car air conditioner is running; if the engine crankshaft speed=0, the signal is β, and the original car air conditioner stops running by default when the engine is turned off. In order not to reduce the cooling effect, the parking air conditioner continues to run at this time; when T≤T1, the signal is C, and the parking air conditioner and the original car air conditioner are all stopped. Through the above control logic, the interconnection control of the whole vehicle refrigeration system is realized.

[0062] Furthermore, in one embodiment, the vehicle refrigerator also includes: a compressor, a condenser and a drying filter connected in sequence; a first evaporator is arranged in the refrigerator body; the output port of the drying filter is also connected to the input port of the first evaporator; the output port of the first evaporator is also connected to the input port of the compressor; the parking air conditioner includes: the compressor, the condenser, the drying filter and the air conditioner indoor unit; a second evaporator is arranged in the air conditioner indoor unit; the output port of the drying filter is also connected to the input port of the second evaporator; the output port of the second evaporator is also connected to the input port of the compressor; the refrigeration system also includes: a multi-channel solenoid valve; the multi-channel solenoid valve is arranged at the output port of the drying filter, and is used to control the refrigerant after passing through the compressor, the condenser and the drying filter to flow to the first evaporator and / or the second evaporator.

[0063] Furthermore, in one embodiment, the output port of the filter drier is connected to the input port of the first evaporator by a first capillary tube; the output port of the filter drier is connected to the input port of the second evaporator by a second capillary tube. In order to make the cooling temperature of the vehicle refrigerator lower than the cooling temperature of the parking air conditioner, the length of the first capillary tube is greater than the length of the second capillary tube.

[0064] That is, in this embodiment, the vehicle refrigerator and the parking air conditioner share a set of compressors, condensers and drying filters. Among them, the compressor is an external compressor, which is different from the original compressor of the original vehicle air conditioner. The external compressor is used to compress the refrigerant into a high-temperature and high-pressure gas, which releases heat after entering the condenser and becomes a high-pressure liquid at room temperature, and then enters the drying filter to remove moisture and impurities. After that, it enters the first evaporator or the second evaporator, and the first evaporator or the second evaporator absorbs heat to reduce the temperature of the surrounding air. The refrigerant circulates in the above-mentioned external compressor, condenser, drying filter and first evaporator to realize the refrigeration function of the vehicle refrigerator; the refrigerant circulates in the above-mentioned external compressor, condenser, drying filter and second evaporator to realize the refrigeration function of the parking air conditioner.

[0065] Specifically, when the power source of the vehicle is the engine, the original vehicle air conditioner is driven by the engine crankshaft. When the engine stops, the original vehicle air conditioner will also stop running. Therefore, the refrigerant system of the original vehicle air conditioner is regarded as an independent system. The vehicle's ECU (Electronic Control Unit) controls the operating state of the original vehicle air conditioner by controlling the electromagnetic clutch, that is, it drives the compressor of the original vehicle air conditioner to operate by controlling the electromagnetic clutch. In this embodiment, the parking air conditioner and the car refrigerator are connected to a refrigerant system and share a set of compressors, so they are not affected by the operating state of the engine. The throttling of the refrigerant is achieved through multiple channels to enable the parking air conditioner and the car refrigerator to reach different temperatures.

[0066] like Figure 3As shown, after the refrigerant passes through the drying filter to remove moisture and impurities, it enters the three groups of channels controlled by the multi-channel solenoid valve. When the multi-channel solenoid valve opens channel 1, channels 2 and 3 are in a closed state, and the refrigerant flows through channel 1 to the first evaporator in the refrigerator body and the second evaporator in the air conditioner, so as to realize the simultaneous refrigeration of the vehicle refrigerator and the parking air conditioner; when the multi-channel solenoid valve opens channel 2, channels 1 and 3 are in a closed state, and the refrigerant can only flow through channel 2 to the first evaporator in the refrigerator body, so as to realize the separate refrigeration of the vehicle refrigerator; when the multi-channel solenoid valve opens channel 3, channels 1 and 2 are in a closed state, and the refrigerant can only flow through channel 3 to the second evaporator in the air conditioner, so as to realize the separate refrigeration of the parking air conditioner. The three groups of channels are all composed of capillaries, and the capillary connected from the solenoid valve to the first evaporator is longer than the capillary connected from the solenoid valve to the second evaporator. Since the longer the capillary, the stronger the refrigeration effect, the refrigeration temperature of the vehicle refrigerator should be lower than the refrigeration temperature of the parking air conditioner to meet the user's temperature usage requirements for the vehicle refrigerator. In this way, the original vehicle air conditioner, parking air conditioner and car refrigerator can operate independently or work together.

[0067] In this embodiment, Figure 3 As shown, sensors (such as temperature sensors, gravity sensors, speed sensors, etc.) transmit the detected data to the ECU, and the ECU controls the action of the electromagnetic clutch and / or electromagnetic valve through the CAN bus to achieve joint control of the original vehicle air conditioner, parking air conditioner and car refrigerator. Figure 4 Taking one of the states shown as an example, when the gravity sensor detects that there are items in the refrigerator box, the speed sensor detects that the engine is in the starting state, and the temperature sensor detects that the current cabin temperature exceeds the upper temperature limit, the ECU controls the electromagnetic clutch to energize through the CAN bus, thereby controlling the original vehicle air conditioner to turn on. At the same time, the ECU controls the solenoid valve to open channel 1 through the CAN bus, so that the refrigerant can flow through channel 1 to the first evaporator in the refrigerator box and the second evaporator in the air conditioner, thereby enabling the vehicle refrigerator and the parking air conditioner to start cooling, that is, controlling the vehicle refrigerator and the parking air conditioner to turn on. The control method for other states is similar to this and will not be repeated here.

[0068] The vehicle refrigeration system control method provided by the embodiment of the present invention obtains the current state information of the power source and the current cabin temperature of the vehicle when receiving the predetermined information, and controls the start and stop of the original vehicle air conditioner and / or the parking air conditioner based on the current state information of the power source and the current cabin temperature, so that the present invention can automatically control the start and stop of the original vehicle air conditioner and / or the parking air conditioner according to the current power source state information and the cabin temperature. Since the original vehicle air conditioner and the parking air conditioner can be automatically turned on or off, the cabin temperature can be automatically adjusted, avoiding the user from performing manual operations according to their own temperature sensation, thereby greatly improving the user experience.

[0069] The present invention integrates the original vehicle air conditioner, parking air conditioner and vehicle refrigerator into an integrated interconnection, realizing integrated control. The refrigerant is shunted through the channel controlled by the vehicle ECU, thereby realizing the functions of the original vehicle air conditioner, parking air conditioner and vehicle refrigerator being able to cool independently and together, meeting the needs of the car owner. After connecting the above three devices, the control logic is designed to realize the automatic control of the system, bringing a convenient and high-end experience to the car owner.

[0070] Corresponding to the above method embodiment, the present invention also provides a vehicle refrigeration system control device, wherein the vehicle includes a power source; the refrigeration system includes: an original vehicle air conditioner and a parking air conditioner. Figure 5 As shown, the device described in this embodiment includes:

[0071] A first acquisition unit 11 is used to acquire current state information of the power source and current cabin temperature of the vehicle when receiving predetermined information;

[0072] The control unit 12 is used to control the start and stop of the original vehicle air conditioner and / or the parking air conditioner based on the current state information of the power source and the current cabin temperature.
