Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0028] Example 1

[0029] Figure 1This is a flow chart of an air compressor control method provided according to the first embodiment of the present invention. This embodiment is applicable to the case of controlling the operating state of an air compressor. The method can be executed by an air compressor control device. The air compressor control device can be implemented in the form of hardware and / or software. The air compressor control device can be configured in a controller. The controller is connected to the air compressor. The air compressor and the controller are integrated in a vehicle. The controller can be a microcontroller, an embedded processor, etc. Figure 1 As shown, the method includes:

[0030] S110 : When the pressure inside the air compressor meets the use requirements of the vehicle, determine the temperature signal, working time, and air compressor speed corresponding to the air compressor.

[0031] The temperature signal includes the ambient temperature of the air compressor, and the air compressor speed indicates the amount of air exchanged between the air compressor and the outside world.

[0032] In this embodiment, the temperature signal can be understood as the ambient temperature around the air compressor, and the ambient temperature can be approximated as the compressor temperature signal. The operating time can be understood as the time from the compressor's shutdown state to this moment. The compressor speed can be understood as the frequency at which the compressor operates, indicating the amount of air exchanged with the outside world.

[0033] Specifically, when the pressure inside the air compressor meets the vehicle's operating requirements, the controller receives data such as the air compressor's temperature signal, operating time, and air compressor speed. The temperature signal can be collected by an ambient temperature sensor and transmitted to the controller via a bus. The air compressor speed can be collected by a pressure sensor and transmitted to the controller via a bus.

[0034] For example, Figure 2 Schematic diagram of the working state of an air compressor provided according to the first embodiment of the present invention. Figure 2 As shown, the vehicle controller is the overall vehicle controller, while the anti-emulsification controller MCU is the controller that controls the air compressor. The two controllers can interact with each other. After the relay provides high voltage to the air compressor, the ambient temperature sensor collects the temperature signal and transmits it to the vehicle controller. The vehicle controller then transmits this temperature signal to the anti-emulsification controller MCU.

[0035] S120: Input the temperature signal, the working time, and the air compressor speed into a water content model to obtain the water content of the air compressor oil.

[0036] The water content of the air compressor oil indicates the water content of the oil in the air compressor.

[0037] In this embodiment, the water content model can be understood as a model for calculating the water content of the air compressor oil. The water content model can be integrated into the controller. The water content of the air compressor oil indicates the water content of the oil in the air compressor. The water content of the air compressor oil can also indicate the degree of emulsification of the air compressor oil.

[0038] Specifically, in the moisture content model, the humidity at the compressor's intake and exhaust ends can be determined based on the ambient temperature signals at those ends. The moisture content of the compressor oil can be determined by integrating the values corresponding to the humidity and compressor speed over the operating time.

[0039] For example, the water content model can be integrated into the anti-emulsification controller MCU, which can sample the temperature signal once every 100 ms and calculate the water content of the air compressor oil.

[0040] S130: Control the operating state of the air compressor according to the water content of the air compressor oil.

[0041] In this embodiment, the operating state indicates the state of the air compressor exchanging air with the outside. The air compressor can discharge air to the outside, stop working, or absorb air from the outside.

[0042] Specifically, when the water content of the air compressor oil is high, it means that there is too much water in the air compressor oil and the water needs to be evaporated, so the operating state can be set to the state of exhausting air. When the water content of the air compressor oil is low, it means that there is less water in the air compressor oil and the air compressor no longer needs to work, so the operating state can be set to stop.

[0043] The technical solution of the embodiment of the present invention determines the temperature signal, operating time, and compressor speed corresponding to the air compressor when the pressure inside the air compressor meets the vehicle's usage requirements. The temperature signal includes the ambient temperature of the air compressor, and the compressor speed indicates the amount of air exchanged between the air compressor and the outside world. The temperature signal, operating time, and compressor speed are input into a water content model to obtain the water content of the air compressor oil. The water content of the air compressor oil indicates the water content of the oil in the air compressor. The operating state of the air compressor is controlled based on the water content of the air compressor oil. By inputting the temperature signal, operating time, and compressor speed into the water content model to calculate the water content of the air compressor oil, the air compressor oil water content is monitored in real time and the operating state of the air compressor is controlled based on the water content of the air compressor oil. This solves the problem of the existing technology that the water content of the air compressor oil cannot be actively controlled, solves the problem of oil emulsification during operation of the air compressor, and reduces resource waste.

[0044] Based on the above embodiment, a modified embodiment of the above embodiment is proposed. It should be noted that, in order to simplify the description, only the differences from the above embodiment are described in the modified embodiment.

[0045] In one embodiment, determining the temperature signal corresponding to the air compressor includes:

[0046] Obtaining an intake temperature and an exhaust temperature corresponding to the air compressor, wherein the intake temperature includes the ambient temperature at the location of the intake end of the air compressor, and the exhaust temperature includes the ambient temperature at the location of the exhaust end of the air compressor. The intake end includes a port for inputting air into the air compressor, and the exhaust end includes a port for exhausting air from the air compressor.

[0047] The intake air temperature and the exhaust air temperature are used as temperature signals corresponding to the air compressor.

[0048] In this embodiment, the air compressor includes an intake end and an exhaust end. The intake end can be used to receive air from the outside, and the exhaust end can be used to discharge air to the outside. Therefore, the temperature signal includes intake temperature and exhaust temperature. The intake temperature can be understood as the temperature around the air compressor intake end and can be collected by an intake temperature sensor. Similarly, the exhaust temperature can be understood as the temperature around the air compressor exhaust end and can be collected by an exhaust temperature sensor.

[0049] Specifically, the intake air temperature obtained by the intake air temperature sensor and the exhaust air temperature obtained by the exhaust air temperature sensor are transmitted to the controller via the bus. The controller receives the intake air temperature and the exhaust air temperature as temperature signals of the air compressor and inputs them into the moisture content model.

[0050] In one embodiment, controlling the operating state of the air compressor according to the water content of the air compressor oil includes:

[0051] When the water content of the air compressor oil is greater than a set threshold, the operating state of the air compressor is controlled to be an idling state, and the idling state indicates that the air compressor is in a state of discharging air outwards;

[0052] When the water content of the air compressor oil is less than or equal to a set threshold, the operating state of the air compressor is controlled to be a shutdown state, and the shutdown state indicates that the air compressor is in a stopped state.

[0053] In this embodiment, the set threshold value may be understood as a threshold value set for the air compressor to indicate the water content of the air compressor oil.

[0054] For example, the threshold value can be set to 0. When the water content of the compressor oil is greater than the set threshold value, that is, when CDW>0, it indicates that the water content of the oil inside the compressor is high and needs to be evaporated. Therefore, the operating state of the compressor is controlled to be idling. In the idling state, the temperature inside the compressor rises, which can evaporate the water. Finally, the water content CDW of the compressor oil is stored in the electrically erasable programmable read-only memory (EEPROM). When the water content of the compressor oil is less than or equal to the set threshold value, that is, when CDW≤0, it indicates that the water content of the oil inside the compressor is low and does not need to be evaporated. Therefore, the operating state of the compressor is controlled to be stopped and the compressor is controlled to be shut down.

[0055] Optionally, after controlling the operating state of the air compressor to be a shutdown state, the method further includes:

[0056] Initialize the water content of the air compressor oil, and when the air compressor starts working again, update the temperature signal, working time and air compressor speed corresponding to the air compressor.

[0057] Specifically, after the air compressor is controlled to be in a shutdown state and the air compressor is shut down, the water content of the air compressor oil is initialized. When the air compressor is operating again, the corresponding temperature signal, air compressor speed, and operating time of the air compressor are re-collected. These re-collected data are input into the water content model to calculate the new water content of the air compressor oil.

[0058] For example, after the air compressor is controlled to stop, the water content in the compressor oil CDW is initialized to 0. When the air compressor is operated next time, the water content in the compressor oil CDW is recalculated.

[0059] In one embodiment, the air compressor control method further includes:

[0060] When the pressure inside the air compressor does not meet the use requirements of the vehicle, the operating state of the air compressor is controlled to be a pumping state, and the pumping state indicates that the air compressor is in a state of absorbing air from the outside.

[0061] Specifically, if the pressure inside the air compressor doesn't meet the vehicle's operating requirements—that is, if the vehicle's system pressure is insufficient—the air compressor needs to draw air from the outside to increase the internal pressure. Therefore, the air compressor's operating state is set to pumping air to meet the vehicle's operating requirements. Once the internal pressure meets the vehicle's requirements, the compressor's operating state can be controlled to idle or shut down, based on the water content in the compressor oil.

[0062] Example 2

[0063] Figure 3This is a flow chart of a method for determining water content according to the second embodiment of the present invention. This embodiment is based on the method for determining water content in the air compressor oil according to the above embodiment. The temperature signal includes the intake temperature and the exhaust temperature. Figure 3 As shown, the method includes:

[0064] S210 : When the pressure inside the air compressor meets the use requirements of the vehicle, determine the temperature signal, working time, and air compressor speed corresponding to the air compressor.

[0065] S220: Look up a table according to the air compressor speed to obtain the air compressor displacement.

[0066] In this embodiment, the air compressor displacement can be understood as the volume of compressed air discharged by the air compressor per unit time.

[0067] For example, according to the air compressor speed, a corresponding table of the air compressor speed signal and the air compressor displacement is obtained, and the air compressor displacement FAD is obtained by looking up the corresponding table.

[0068] S230: Input the working time, the air compressor displacement, the intake temperature, and the exhaust temperature into the water content model for calculation to obtain the water content of the air compressor oil.

[0069] For example, the operating time T, compressor displacement FAD, intake air temperature, and exhaust air temperature are input into the moisture content model. Based on the intake air temperature, the intake air absolute humidity d1 is calculated, and based on the exhaust air temperature, the exhaust air saturation humidity d2 is calculated. The intake air absolute humidity indicates the humidity at the compressor intake end, while the exhaust air saturation humidity indicates the humidity at the compressor exhaust end. Based on the operating time T, compressor displacement FAD, intake air absolute humidity d1, and exhaust air saturation humidity d2, the moisture content (CDW) of the compressor oil is calculated in the moisture content model.

[0070] Optionally, the step of inputting the operating time, the air compressor displacement, the intake temperature, and the exhaust temperature into the water content model for calculation to obtain the water content of the air compressor oil includes:

[0071] The moisture model performs the following operations:

[0072] The absolute humidity of the intake air is calculated based on the intake air temperature, and the saturated humidity of the exhaust air is calculated based on the exhaust air temperature;

[0073] Determining the difference between the intake air absolute humidity and the exhaust air temperature saturation humidity to obtain a humidity difference;

[0074] determining a moisture accumulation rate by multiplying the humidity difference by the air compressor displacement, the moisture accumulation rate indicating the weight of water accumulated in the air compressor;

[0075] The moisture accumulation rate is integrated according to the working time to obtain the water content of the air compressor oil.

[0076] In this embodiment, the humidity difference can be understood as the humidity difference between the air compressor intake end and the exhaust end. The moisture accumulation rate can be understood as the weight of water accumulated in the oil in the air compressor, and the moisture accumulation rate indicates the weight of water in the air compressor oil.

[0077] Exemplarily, the moisture content model performs the following operations: Using a table lookup, the intake air absolute humidity d1 can be calculated based on the intake air temperature, and the exhaust air saturation humidity d2 can be calculated based on the exhaust air temperature. The humidity difference d3 is calculated as = intake air absolute humidity d1 - exhaust air saturation humidity d2. The moisture accumulation rate D3 is calculated as = humidity difference d3 * compressor displacement FAD. The moisture accumulation rate D3 is integrated over the operating time T to obtain the compressor oil water content CDW.

[0078] S240: Control the operating state of the air compressor according to the water content of the air compressor oil.

[0079] The technical solution of the embodiment of the present invention uses a table lookup based on the compressor speed to obtain the compressor displacement; the operating time, the compressor displacement, the intake temperature, and the exhaust temperature are input into the moisture content model for calculation to obtain the water content of the compressor oil. By inputting the compressor temperature signal, operating time, and compressor speed into the moisture content model to calculate the water content of the compressor oil, accurate calculation of the water content of the compressor oil is achieved, solving the resource waste problem caused by regular oil changes, installation of an oil-water separator, or increased compressor operating time in the prior art.

The temperature signal, the operating time, and the air compressor speed are input into a water content model to obtain the water content of the air compressor oil, which indicates the water content of the oil in the air compressor. The operating state of the air compressor is controlled based on the water content of the air compressor oil. By inputting the temperature signal, working time and speed of the air compressor into the water content model, the water content of the air compressor oil is calculated, thereby realizing real-time monitoring of the water content of the air compressor oil. The operating state of the air compressor is controlled by the water content of the air compressor oil, thus solving the problem that the existing technology cannot actively control the water content of the air compressor oil, solving the problem of oil emulsification during the operation of the air compressor, and reducing resource waste.
