[0023] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0024] The following describes the air compressor control method, device, vehicle, storage medium and program product of the embodiment of the present application with reference to the accompanying drawings. In view of the problem that the heavy truck braking system mentioned in the above background technology cannot adjust the air pressure according to the empty or full-load state of the vehicle, resulting in unnecessary high air pressure when idling and consuming extra energy, and the waste of compressed air may be caused by the high air pressure triggering ABS, etc., the present application provides an air compressor control method, in which the load coefficient of the vehicle is obtained, and the air pressure stop threshold of the air compressor is calculated according to the load coefficient of the vehicle, and the air compressor is controlled to supply air to the braking system of the vehicle according to the air pressure stop threshold. By introducing the vehicle load information, the system pressure of the vehicle is different when the vehicle is in different load states, and the smaller the exhaust pressure, the higher the efficiency of the air compressor and the lower the energy consumption. Thus, the problem that the heavy truck braking system cannot adjust the air pressure according to the empty or full-load state of the vehicle, resulting in unnecessary high air pressure when idling and consuming extra energy, and the waste of compressed air may be caused by the high air pressure triggering ABS, etc. is solved.

[0025] Specifically, Figure 1 A flow chart of an air compressor control method provided in an embodiment of the present application.

[0026] like Figure 1As shown in the figure, the air compressor control method includes the following steps:

[0027] In step S101, obtain the load factor of the vehicle.

[0028] Among them, the load factor of the vehicle needs to be calculated based on the data obtained by devices such as axle load sensors. Specifically, in the embodiments of the present application, obtaining the load factor of the vehicle includes: obtaining the vehicle's overall axle load data; calculating the load factor of the vehicle based on the overall axle load data.

[0029] Among them, the overall axle load data refers to the weight distribution borne by each axle of the vehicle, and can be obtained by monitoring the force on each axle in real time through axle load sensors installed on the suspension system or axles.

[0030] It can be understood that in the embodiments of the present application, the overall axle load data of the vehicle is measured by devices such as axle load sensors installed on the axles, and the load factor of the vehicle is calculated based on the overall axle load data, so as to evaluate the current load status of the vehicle.

[0031] In step S102, calculate the air pressure stop threshold of the air compressor according to the load factor of the vehicle.

[0032] It can be understood that in the embodiments of the present application, the air pressure stop threshold of the air compressor is calculated according to the load factor of the vehicle, that is, the load factor is used to evaluate the required air pressure level for current braking, so as to achieve the purpose of energy conservation and emission reduction. Specifically, as follows:

[0033] In the embodiments of the present application, calculating the air pressure stop threshold of the air compressor according to the load factor of the vehicle includes: obtaining the model of the vehicle; determining the curve graph of the load factor and the air pressure stop threshold according to the model of the vehicle; determining the air pressure stop threshold corresponding to the load factor of the vehicle based on the curve graph.

[0034] Among them, since different vehicle models have different design standards and parameters, which will affect how to match the load factor with the corresponding air pressure requirements, it is necessary to determine the curve graph of the load factor and the air pressure stop threshold according to the model of the vehicle. The drawing method of this curve graph will be described in detail below and will not be elaborated here.

[0035] It can be understood that in the embodiments of the present application, by obtaining the specific model of the target vehicle, determining the relationship curve graph between its unique load factor and the air pressure stop threshold, and finding the corresponding point on the curve graph based on the real-time monitored vehicle load factor, the most suitable air pressure stop threshold at this time can be determined. Thus, the operation of the air compressor is accurately adjusted according to the current actual loading situation of the vehicle, achieving the purpose of energy conservation and emission reduction.

[0036] In the embodiments of the present application, before determining the curve graph of the load coefficient and the air pressure stop threshold according to the vehicle model, it further includes: obtaining the braking experiment data of different model vehicles under different loads; extracting the target braking force required by different model vehicles under different loads from the braking experiment data; calculating the air pressure stop threshold of the air compressor for different model vehicles under different loads according to the target braking force, and generating a curve graph based on the air pressure stop threshold of the air compressor for different model vehicles under different loads.

[0037] It can be understood that to generate the curve graph of the load coefficient and the air pressure stop threshold in the embodiments of the present application, it is necessary to obtain the braking experiment data of different model vehicles under different load conditions through a series of braking experiments. These data include but are not limited to parameters such as braking distance, response time, and stability of the vehicle under different load conditions. Calculate the target braking force required by each vehicle model under different loads from these experimental data, and further determine the minimum air pressure stop threshold that the air compressor needs to maintain in the corresponding situation according to the calculated target braking force. Finally, use the obtained data to draw the curve graph between the load coefficient and the air pressure stop threshold for each vehicle model.

[0038] In step S103, control the air compressor to supply air to the braking system of the vehicle according to the air pressure stop threshold.

[0039] It can be understood that the air pressure stop threshold required for the current load of the vehicle obtained by the embodiments of the present application through the above steps is used to control the air compressor to supply air to the braking system of the vehicle, so as to achieve the braking effect and save energy. Specifically as follows:

[0040] In the embodiments of the present application, controlling the air compressor to supply air to the braking system of the vehicle according to the air pressure stop threshold includes: obtaining the current pressure of the braking system; if the current pressure is greater than the air pressure start threshold of the air compressor, control the air compressor to start, and the air compressor starts to supply air to the braking system; if the current pressure is less than the air pressure stop threshold, control the air compressor to stop supplying air.

[0041] Among them, the current pressure of the braking system refers to the real-time pressure level in the vehicle braking system, and this value will change according to the usage of the system, such as braking operations and the working state of the air compressor; the air pressure start threshold is specifically set according to actual needs and is not specifically limited here. When the pressure of the braking system is lower than this set value, the air compressor will automatically start to increase the pressure in the system to ensure that the braking system always has sufficient pressure to cope with possible braking requirements.

[0042] It can be understood that in the embodiments of the present application, the current pressure value of the vehicle braking system is first obtained, and then it is compared with the air pressure start threshold and the air pressure stop threshold. If the current pressure is lower than the air pressure start threshold, it indicates that the braking system needs to supplement gas to maintain sufficient braking force. At this time, the control system will command the air compressor to start and begin to supply gas to the braking system; on the contrary, if the current pressure reaches or exceeds the air pressure stop threshold, it indicates that the braking system already has sufficient air pressure reserve and no further inflation is required. At this time, the control system will instruct the air compressor to stop working, thereby avoiding waste and additional energy consumption caused by excessive air compression, effectively managing the working cycle of the air compressor, ensuring driving safety, and achieving effective utilization of energy.

[0043] In the embodiments of the present application, before controlling the air compressor to supply gas to the braking system of the vehicle according to the air pressure stop threshold, it further includes: obtaining the unloading pressure of the dryer of the vehicle; correcting the air pressure stop threshold according to the unloading pressure of the dryer.

[0044] Among them, the air dryer in the vehicle braking system is used to remove moisture in the compressed air to prevent pipeline corrosion and freezing. After the air compressor stops working, in order to prevent the air pressure in the system from being too high or to facilitate the next start, the dryer will release a part of the pressure gas, and the pressure value when the gas starts to be released is the unloading pressure of the dryer.

[0045] It can be understood that in the embodiments of the present application, before controlling the air compressor to supply gas to the braking system, in addition to determining the air pressure stop threshold according to the current load state, it is also necessary to obtain the unloading pressure parameter of the vehicle dryer. Since the dryer will automatically exhaust gas at a certain air pressure to protect the safe operation of itself and the system, this exhaust behavior will affect the actual available air pressure level of the braking system. Therefore, it is necessary to correct the originally calculated air pressure stop threshold according to the unloading pressure of the dryer. For example, if the unloading pressure of the dryer is lower than the original air pressure stop threshold, the air pressure stop threshold needs to be appropriately reduced to ensure that the air compressor can effectively supply gas to the system before the dryer starts to unload, and to avoid frequent start and stop caused by air pressure fluctuations. Through this correction process, the working state of the air compressor can be more precisely controlled, and the system efficiency and stability can be improved.

[0046] According to the air compressor control method proposed by the embodiments of the present application, by obtaining the load coefficient of the vehicle, calculating the air pressure stop threshold of the air compressor according to the load coefficient of the vehicle, and controlling the air compressor to supply gas to the braking system of the vehicle according to the air pressure stop threshold, by introducing vehicle load information, the pressure provided by the air compressor is different when the vehicle is in different load states. Since providing high pressure will cause low efficiency of the air compressor, when the vehicle load is small, the air compressor provides an appropriate smaller pressure, so that the higher the power of the air compressor, the lower the energy consumption, realizing more precise control of the working state of the air compressor and improving the system efficiency and stability.

[0047] The air compressor control method will be further described below through a specific embodiment. As Figure 2 shown, the dashed line represents the transmission of control information, and the solid line represents the transmission of compressed air. It includes an air compressor, a gas supply module controller, an electronic control processing unit, an air storage tank 1, an air storage tank 2, and a vehicle axle load sensor.

[0048] Specifically, the gas supply module controller obtains information such as the real-time collected current vehicle axle load by the axle load sensor, determines the vehicle load coefficient, and compares it with the MAP of the load coefficient and air pressure pre-stored in the controller module, as Figure 3 shown, to determine the air pressure corresponding to the current vehicle load coefficient.

[0049] The air pressure information corresponding to the current load state of the vehicle is given to the air compressor, and the air compressor supplies air to the braking system as required. On the basis of detecting the original air storage tank pressure information, the vehicle load information is introduced, so that the system pressure is different when the vehicle is in different load states. Since providing high pressure will cause low efficiency of the air compressor, when the vehicle load is small, the air compressor provides an appropriate smaller pressure, making the air compressor more efficient and consuming less energy. It realizes more precise control of the working state of the air compressor and improves the system efficiency and stability.

[0050] Next, the air compressor control device according to the embodiment of the present application will be described with reference to the accompanying drawings.

[0053] Among them, the acquisition module 201 is used to acquire the load coefficient of the vehicle; the calculation module 202 is used to calculate the air pressure stop threshold of the air compressor according to the load coefficient of the vehicle; the control module 203 is used to control the air compressor to supply air to the braking system of the vehicle according to the air pressure stop threshold.

[0054] In the embodiment of the present application, the calculation module 202 is further used to: obtain the model of the vehicle; determine the curve graph of the load coefficient and the air pressure stop threshold according to the model of the vehicle; and determine the air pressure stop threshold corresponding to the load coefficient of the vehicle based on the curve graph.

[0055] In an embodiment of the present application, a generation module is further included. The generation module is further configured to: before determining a curve graph of a load coefficient and a pneumatic stop threshold according to the vehicle model, obtain braking experiment data of different vehicle models under different loads; extract the target braking force required by different vehicle models under different loads from the braking experiment data; calculate the pneumatic stop threshold of the air compressor for different vehicle models under different loads according to the target braking force, and generate a curve graph according to the pneumatic stop threshold of the air compressor for different vehicle models under different loads.

[0056] In an embodiment of the present application, the control module 203 is further configured to: obtain the current pressure of the braking system; if the current pressure is greater than the pneumatic start threshold of the air compressor, control the air compressor to start, and the air compressor starts to supply air to the braking system; if the current pressure is less than the pneumatic stop threshold, control the air compressor to stop supplying air.

[0057] In an embodiment of the present application, a correction module is further included. The correction module is further configured to: before controlling the air compressor to supply air to the braking system of the vehicle according to the pneumatic stop threshold, obtain the unloading pressure of the dryer of the vehicle; correct the pneumatic stop threshold according to the unloading pressure of the dryer.
