Detailed Implementation

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0023] According to an embodiment of this application, an embodiment of a valve control method in a vehicle is provided. The steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0024] Currently, most air pressure braking systems use an air handling unit (mechanical type). The air pressure in the air tank (also known as an air reservoir) controls the opening and closing of the unloading valve and regeneration valve of the air handling unit. Therefore, in this structure, the unloading pressure and regeneration amount are fixed and cannot be adjusted according to the vehicle characteristics.

[0025] Some vehicle models have begun to adopt electronically controlled air handling units (ETUs), which can control unloading and regeneration as needed. However, even in models using ETUs, the systems are not tailored to specific scenarios. For example, while the system's unloading and regeneration can be controlled by solenoid valves, achieving electronic control, the unloading and regeneration operations are only performed based on air pressure signals, without defining different operating modes for specific scenarios.

[0026] In related technologies, using electronically controlled air compressors to control intermittent air supply according to different operating modes can achieve energy-saving effects. However, the unloading and regeneration processes during air compressor operation are not defined, thus posing a technical problem of high energy consumption in the air supply system.

[0027] To address the aforementioned issues, in this embodiment, an electronically controlled air handling unit performs unloading and regeneration control based on the vehicle's operating status, maximizing the use of engine running time for energy storage and regeneration, reducing the frequency of air compressor (located on the hybrid vehicle's engine, starting or stopping synchronously with the engine) startup, and decreasing air consumption in pure electric mode, thereby achieving energy conservation.

[0028] Optionally, the embodiment proposes a valve control method in a vehicle. When the vehicle is powered on, the method determines the start / stop status of the engine and the gas filtration rate of the dryer. Based on the start / stop status and gas filtration rate, the operating mode of the air supply system is determined. Different operating modes are matched with different judgment conditions. Based on the judgment conditions, the current air supply system is judged to obtain the corresponding control strategy for the air supply system. This achieves the goal of improving the utilization rate of high-pressure air, avoiding frequent engine starts in hybrid vehicles and high energy consumption of the air supply system, thereby achieving the technical effect of reducing the energy consumption of the air supply system and solving the technical problem of high energy consumption of the air supply system.

[0029] Figure 1 This is a flowchart of a valve control method in a vehicle according to an embodiment of this application. Figure 1 As shown, the method may include the following steps: Step S102: In response to the vehicle being powered on, determine the start / stop status of the engine in the vehicle and the gas filtration capacity of the dryer canister in the vehicle, wherein the dryer canister is deployed in the vehicle's air supply system, and the operating status of the air compressor in the air supply system is the same as the operating status of the engine.

[0030] In the technical solution provided in step S102 of this application, the gas filtration capacity can be represented by N, which can be a characterizing the humidity of the dryer or the amount of gas filtered by the dryer. The calculation of N can be performed within a controller of the vehicle. When the air tank is filled with gas, the value of N increases; during regeneration, the value of N decreases; when neither filling nor regeneration occurs, the value of N remains unchanged. The aforementioned air supply system can be a pneumatic braking system, also known as a pneumatic braking air supply system, and can consist of an air compressor, an air handling unit, and an air tank. It should be noted that this is merely an example, and no specific limitations are placed on the composition and structure of the air supply system.

[0031] Optionally, the aforementioned gas filtration capacity can be an indicator used to characterize the humidity of the dryer can or the amount of gas filtered by the dryer can. This value can be determined within a controller in the vehicle and can reflect the dryness of the air inside the dryer can or its operational status. When the air supply system fills the air tank, the N value increases, meaning the dryer can process more air, and the humidity inside the dryer can potentially rise. Conversely, when the air supply system performs regeneration, the N value decreases, indicating that the humidity of the dryer can be reduced and its drying capacity restored. In a stable state without filling or regeneration, the N value remains unchanged. By monitoring and controlling the N value, the regeneration strategy of the air handling unit can be adjusted to optimize the performance and energy efficiency of the pneumatic braking system.

[0032] Optionally, the air compressor in the air supply system is located on the vehicle's engine. The air compressor starts when the engine starts and stops when the engine stops. The air compressor is connected to an air handling unit (ALU), which in turn connects to an air tank. When the air compressor is working, it generates high-pressure air, which flows through the ALU and into the air tank for storage. The ALU contains a dryer, whose function is to dry the air. When the pressure in the air tank reaches the set unloading pressure, the unloading solenoid valve of the ALU opens. If the vehicle requires the engine to continue running (i.e., the air compressor continues to work), the air compressor will continue to generate high-pressure air, but it will no longer flow into the air tank; instead, it will be discharged into the atmosphere through the unloading valve of the ALU. If the vehicle no longer needs to run the engine, the air compressor will stop. When the unloading solenoid valve is open, the regeneration solenoid valve of the ALU can be optionally opened. If opened, the high-pressure air in the air tank will flow back through the ALU, carrying away moisture from the dryer and thus maintaining the dryer's drying capacity.

[0033] Hybrid electric vehicles can operate in three modes: pure electric drive mode, engine drive mode, and a combined pure electric and engine drive mode (some models may not have this mode). In pure electric drive mode, when the air tank pressure is too low and needs to be refilled, the engine needs to start, consuming additional energy. In engine drive mode (or combined pure electric and engine drive mode), the air compressor continuously generates high-pressure air as the engine runs, so refilling the air tank does not require additional energy. Therefore, generating high-pressure air in pure electric drive mode consumes more energy, while generating high-pressure air in engine drive mode (or combined pure electric and engine drive mode) consumes less energy. The core idea of ​​this patent is to minimize high-pressure air consumption in pure electric mode and shift air usage to engine mode (or combined pure electric and engine drive mode), while storing more high-pressure air in engine mode to reduce energy consumption.

[0034] Step S104: Determine the operating mode of the gas supply system based on the start / stop status and gas filtration volume.

[0035] In the technical solution provided in step S104 of this application, different start / stop states and different working modes of the gas supply system corresponding to different gas filtration rates can be preset. Therefore, after determining the start / stop state and gas filtration rate, the working mode of the gas supply system can be determined based on the start / stop state and gas filtration rate. The aforementioned working modes may include, but are not limited to: the first working mode (Mode A), the second working mode (Mode B), the third working mode (Mode C), the fourth working mode (Mode D), the fifth working mode (Mode E), the sixth working mode (Mode F), and the sixth working mode (Mode G). It should be noted that the types of working modes here are only illustrative and are not specifically limited; working modes can be deleted or added according to actual needs.

[0036] Step S106: In response to the gas pressure value of the gas storage tank in the gas supply system, if the judgment condition associated with the working mode is met, a control strategy matching the working mode is determined. The judgment condition is used to determine the opening and closing state of at least one valve in the gas supply system, and the control strategy is used to represent the rules for controlling the opening and closing of at least one valve.

[0037] In the technical solution provided in step S106 of this application, different operating modes are associated with different judgment conditions. Therefore, after determining the operating mode, the judgment conditions associated with the current operating mode can be determined. Based on the judgment conditions, the gas pressure value of the gas storage tank is judged. Based on the judgment result, a control strategy matching the current operating mode can be determined. The control strategy represents the rules for controlling the opening and closing of at least one valve. The aforementioned judgment conditions are used to determine the open / closed state that at least one valve in the gas supply system should be in.

[0038] Optionally, the operating mode of the gas supply system is first determined based on the start / stop status and gas filtration rate. After determining the operating mode, different judgment conditions are corresponding to different operating modes. Based on these judgment conditions, the gas pressure value is judged, thereby determining whether at least one valve should be closed or opened, to obtain the corresponding control strategy for that operating mode and that gas pressure value.

[0039] For example, if the gas supply system is operating in mode C, the pre-set condition for mode C is that the gas pressure value is greater than the target value Y2. Therefore, the current gas pressure value of the storage tank is assessed using this condition. If the result indicates that the gas pressure value of the storage tank in the gas supply system meets the condition associated with the operating mode (i.e., the gas pressure value is greater than the target value Y2), then the corresponding control strategy is determined to be: opening both the regeneration solenoid valve and the unloading solenoid valve in the gas supply system. It should be noted that the operating mode and condition described here are merely illustrative and are not subject to specific limitations.

[0040] Step S108: According to the control strategy, control the opening and closing of at least one valve to control the working process of the drying tank.

[0041] In the technical solution provided in step S108 of this application, the opening and closing of at least one valve in the vehicle can be controlled according to a control strategy. By controlling the opening and closing of the valve, the working process of the dryer can be controlled. This working process may include, but is not limited to, the regeneration process of the dryer pipe, the exhaust process, and the intake process. It should be noted that this is only an example and does not impose specific limitations on the working process.

[0042] Through steps S102 to S108 of this application, in response to the vehicle being powered on, the start / stop state of the engine in the vehicle and the gas filtration rate of the dryer can in the vehicle are determined, wherein the dryer can be deployed in the vehicle's air supply system, and the working state of the air compressor in the air supply system is the same as the working state of the engine; based on the start / stop state and the gas filtration rate, the operating mode of the air supply system is determined; in response to the gas pressure value of the air tank in the air supply system, if the judgment condition associated with the operating mode is met, a control strategy matching the operating mode is determined, wherein the judgment condition is used to determine the opening / closing state of at least one valve in the air supply system, and the control strategy is used to represent the rule for controlling the opening and closing of at least one valve; according to the control strategy, the opening and closing of at least one valve is controlled to control the working process of the dryer can. That is, in the embodiments of this application, when the vehicle is powered on, the start-stop state of the engine in the vehicle and the gas filtration amount of the dryer are determined. Based on the start-stop state and the gas filtration amount, the working mode of the gas supply system is determined. Different working modes are matched with different judgment conditions. Based on the judgment conditions, the current gas supply system is judged to obtain the corresponding control strategy of the gas supply system, thereby achieving the technical effect of reducing the energy consumption of the gas supply system and solving the technical problem of high energy consumption of the gas supply system.

[0043] The method described in this embodiment will be further described below.

[0044] As an optional implementation, step S104, based on the start / stop state and the gas filtration rate, determines the operating mode of the gas supply system, including: in response to the start / stop state being in a stopped state and the gas filtration rate being within a first threshold range, determining the operating mode as a first operating mode; in response to the start / stop state being in a stopped state and the gas filtration rate being greater than the maximum value in the first threshold range, determining the operating mode as a second operating mode, wherein the first operating mode and the second operating mode are different.

[0045] In this embodiment, the first working mode can be mode A, or a preset mode, without specific limitations. The second working mode can be mode B. The threshold range can be a preset range. The first threshold range can be between 0 and c1, where c1 can be a preset value or a value determined experimentally, without specific limitations on the value of c1.

[0046] Optionally, this embodiment proposes a control method for a pneumatic braking air supply system. Based on two states—engine shutdown and engine operation—the air supply system mainly operates in two modes: when the engine is shut down, it operates in either the first mode (Mode A) or the second mode (Mode B); when the engine is running, it operates in either the third mode (Mode C), the fourth mode (Mode D), or the fifth mode (Mode E). In Mode A, regeneration only occurs when the N value is high, and the maximum regeneration time is limited. When the N value is particularly high, it enters Mode B, where regeneration occurs every time the load is unloaded until the N value drops below a set value or the air tank pressure becomes too low.

[0047] Optionally, the air supply system operates in function modes A and B only when the vehicle is in pure electric drive mode. The purpose of the above strategy is to perform only the regeneration necessary to ensure the normal operation of the braking system in function modes A and B (vehicle in pure electric state) to ensure that the brake lines are dry, and to avoid unnecessary regeneration.

[0048] Optionally, when already in mode B, even if N decreases to less than c1, it will not switch to mode A until N is less than d1, at which point it will switch to mode A.

[0049] For example, when the start / stop state is stopped and the gas filtration rate is between 0 and c1, the operating mode can be determined to be the first operating mode, where c1 can be a preset value. When the start / stop state is stopped and the gas filtration rate is greater than c1, the operating mode can be determined to be the second operating mode, where the first operating mode and the second operating mode are different.

[0050] As an optional implementation, in response to the gas pressure value of the gas storage tank in the gas supply system, and satisfying the judgment condition associated with the working mode, a control strategy matching the working mode is determined, including: in response to the working mode being a first working mode, determining the judgment condition as a first judgment condition, wherein the first judgment condition is that the gas pressure value is greater than a first target value; in response to the gas pressure value satisfying the first judgment condition and the gas filtration rate being within a second threshold range, determining the control strategy as a first control strategy, wherein the first control strategy is used to control the opening of the regeneration solenoid valve in the gas supply system and to control the opening of the unloading solenoid valve in the gas supply system, the first threshold range including the second threshold range; in response to the gas filtration rate being less than the lower limit of the second threshold range, determining the control strategy as a second control strategy, wherein the second control strategy is used to control the closing of the regeneration solenoid valve in the gas supply system and to control the opening of the unloading solenoid valve in the gas supply system.

[0051] In this embodiment, if the operating mode is the first operating mode, the determination condition is the first determination condition, which is that the gas pressure value is greater than the first target value (Y1). If the gas pressure value meets the first determination condition, it is determined whether the gas filtration amount is within the second threshold range (e1 to c1). If the gas filtration amount is within the second threshold range, the control strategy is determined to be the first control strategy, wherein the first control strategy is used to control the opening of the regeneration solenoid valve in the gas supply system and to control the opening of the unloading solenoid valve in the gas supply system. If the gas filtration amount is less than the minimum value of the second threshold range, that is, the lower limit value (e1), the control strategy is determined to be the second control strategy, wherein the second control strategy is used to control the closing of the regeneration solenoid valve in the gas supply system and to control the opening of the unloading solenoid valve in the gas supply system, wherein e1 can be a preset value.

[0052] Optionally, after the vehicle is powered on, it defaults to Function A mode. In Function A mode, the air supply pressure of the air supply system is X1, and the unloading pressure is Y1. When the air pressure in the air tank is lower than X1, both the unloading solenoid valve and the regeneration solenoid valve of the air handling unit are closed, and air is started to fill the air tank. When the air pressure in the air tank is higher than Y1 (that is, the air pressure value is greater than the first target value), it is determined that the air pressure value meets the first judgment condition. At this time, the unloading solenoid valve opens, and air filling to the air tank stops. Further, according to the value of N at the unloading time, the regeneration solenoid valve has two working states: when e1≤N<c1 (that is, the gas filtration rate is within the second threshold range), the regeneration solenoid valve opens to regenerate the dryer until N≤f1 or the maximum regeneration time t1 is reached or the air tank pressure is lower than X1; when N<e1 (that is, the gas filtration rate is less than the minimum value of the threshold range), the regeneration solenoid valve closes and no regeneration is performed. Here, e1 can be a value determined in advance based on experiments or tests, and the magnitude of e1 is not specifically limited here.

[0053] Optionally, in response to the air pressure value not satisfying the first judgment condition, control the unloading solenoid valve to close and the regeneration solenoid valve to close.

[0054] As an optional implementation manner, in response to the air pressure value of the air storage tank in the air supply system satisfying the judgment condition associated with the working mode, determine the control strategy matching the working mode, including: in response to the working mode being the second working mode, determine the judgment condition as the first judgment condition; in response to the air pressure value satisfying the first judgment condition, determine the control strategy as the first control strategy.

[0055] In this embodiment, in the A function mode, when N≥c1, enter the B function mode.

[0056] Optionally, in the B function mode, the supply air pressure is X1, and the unloading pressure is Y1. When the air pressure in the air storage tank is lower than X1, both the unloading solenoid valve and the regeneration solenoid valve of the air treatment unit are closed, and inflation starts for the air storage tank. When the air pressure in the air storage tank is higher than Y1, it can be determined that the air pressure value satisfies the first judgment condition. At this time, the control strategy can be determined as the first control strategy: control the unloading solenoid valve to open, stop inflating the air storage tank, and at the same time, control the regeneration solenoid valve to open, and the system performs regeneration until N≤d1 or the air storage tank pressure is lower than X1 (at this time, the maximum regeneration time is no longer restricted), where f1<e1<d1<c1 and X1<Y1. It should be noted that the magnitudes of f1, e1, d1, c1, X1, and Y1 can be set according to actual requirements, and no specific restrictions are imposed on the magnitudes of the above parameters here.

[0057] As an optional implementation manner, based on the start-stop state and the gas filtration volume, determine the working mode of the air supply system, including: in response to the start-stop state being the start state and the gas filtration volume being less than or equal to the second target value, obtain the vehicle speed and the engine speed, where the second target value is less than the maximum value in the first threshold range; in response to the vehicle speed being less than or equal to the third target value and the speed being less than or equal to the fourth target value, determine the working mode as the third working mode, where the third working mode is different from the first working mode; in response to the vehicle speed being greater than the third target value or the speed being greater than the fourth target value, determine the working mode as the fourth working mode, where the fourth working mode is different from the third working mode; in response to the start-stop state being the start state and the gas filtration volume being greater than the second target value, determine the working mode as the fifth working mode, where the fifth working mode is different from the fourth working mode.

[0058] In this embodiment, when the engine is running, it operates in the C, D, and E modes. Among them, the above second target value can be represented by c2, which can be a value determined in advance through experiments or tests, and c2 is less than c1. No specific restrictions are imposed on the magnitude of c2 here.

[0059] Optionally, when the vehicle speed and engine speed are low, it operates in the third working mode (Mode C). In Mode C, regeneration occurs with each unloading until the N value drops very low, the air tank pressure is too low, or the regeneration time reaches the set maximum regeneration time. When the vehicle speed or engine speed is high, it operates in the fourth working mode (Mode D). In Mode D, regeneration occurs with each unloading until the N value drops very low, the air tank pressure is too low, or the regeneration time reaches the set longer maximum regeneration time. When the N value is high (regardless of vehicle speed or engine speed), it operates in the fifth working mode (Mode E). In Mode E, regeneration occurs with each unloading until the N value drops very low, or the air tank pressure is too low. If the vehicle speed or engine speed signal fails or is lost, it defaults to operating in Mode C. When the vehicle is powered off and the air tank pressure is sufficient, regeneration is performed for a fixed period of time to keep the dryer canister dry when the vehicle is parked for a long time, thus improving the lifespan of the dryer canister. When the system pressure signal fails, a "charge-unloading regeneration-unloading" cycle is performed to ensure basic air supply and air drying.

[0060] Optionally, if the engine is running and the gas filtration rate is less than or equal to the second target value (c2), then the system can operate in either the third or fourth operating mode. Further judgment can be made based on vehicle speed and engine speed. If the vehicle speed is less than or equal to the third target value (a) and the engine speed is less than or equal to the fourth target value (b), the operating mode is determined to be the third operating mode (mode C), which differs from the first operating mode. If the vehicle speed is greater than the third target value or the engine speed is greater than the fourth target value, the operating mode is determined to be the fourth operating mode (mode D), which differs from the third operating mode. If the start-stop system is running and the gas filtration rate is greater than the second target value (c2), then the operating mode is determined to be the fifth operating mode (mode E), which differs from the fourth operating mode.

[0061] Optionally, in function E mode, when N is less than or equal to d2, the system will enter function C or D mode based on vehicle speed and engine speed. Here, d2 can be a preset value or a value set according to testing or actual needs.

[0062] As an optional implementation, in response to the gas pressure value of the gas storage tank in the gas supply system, and satisfying the judgment condition associated with the working mode, a control strategy matching the working mode is determined, including: in response to the working mode being a third working mode, determining the judgment condition as a second judgment condition, wherein the second judgment condition is that the gas pressure value is greater than a sixth target value, and the sixth target value is greater than or equal to a first target value; in response to the gas pressure value satisfying the second judgment condition, determining the control strategy as a third control strategy, wherein the third control strategy is used to control the opening of the regeneration solenoid valve in the gas supply system, and to control the opening of the unloading solenoid valve in the gas supply system.

[0063] In this embodiment, when the engine is started, it defaults to the C function mode. In this function mode, the vehicle speed is less than or equal to the third target value, the rotational speed is less than or equal to the fourth target value, and the gas filtration amount is less than or equal to the second target value. In the C function mode, the system supply pressure is X2, and the unloading pressure is Y2. When the air pressure in the gas storage tank is lower than X2, the unloading solenoid valve and the regeneration solenoid valve of the air treatment unit are both closed, and inflation of the gas storage tank starts. When the air pressure in the gas storage tank is higher than the sixth target value (Y2), it can be determined that the air pressure value meets the second judgment condition, and then it can be determined that the control strategy is the third control strategy, which can be: the unloading solenoid valve is opened, inflation of the gas storage tank stops, and at the same time the regeneration solenoid valve is opened, and the system performs regeneration until N≤f2 or the maximum regeneration time t2 is reached or the air pressure in the gas storage tank is lower than X2. Here, Y2>X2, X2>X1, Y2≥Y1, the purpose is to store as much high-pressure air as possible when the engine starts. f2<f1, the purpose is to make the regeneration as complete as possible when the engine starts and reduce the gas consumption during regeneration in pure electric drive. It should be noted that the magnitudes of Y2, X2, X1, and Y1 can be set according to actual requirements and are not specifically limited here.

[0064] Optionally, in the C function mode, when the vehicle speed > a or the engine rotational speed > b, it enters the D function mode. In the C function mode, when N>c2, it enters the E function mode. Here, c2<c1, the purpose is to make the regeneration as complete as possible when the engine starts. The priority of the E function mode is higher than that of the D function mode.

[0065] As an optional implementation manner, in response to the air pressure value in the gas storage tank of the air supply system meeting the judgment condition associated with the working mode, determining the control strategy matching the working mode includes: in response to the working mode being the fourth working mode, determining that the judgment condition is the second judgment condition; in response to the air pressure value meeting the second judgment condition, determining that the control strategy is the third control strategy.

[0066] In this embodiment, in the D function mode, the system supply pressure is X2, and the unloading pressure is Y2. When the air pressure in the gas storage tank is lower than X2, the unloading solenoid valve and the regeneration solenoid valve of the air treatment unit are both closed, and inflation of the gas storage tank starts. When the air pressure in the gas storage tank is higher than Y2, the unloading solenoid valve is opened, inflation of the gas storage tank stops, and at the same time the regeneration solenoid valve is opened, and the system performs regeneration until N≤f2 or the air pressure in the gas storage tank is lower than X2 or the maximum regeneration time t3 is reached. Here, t3>t2 and t3>t1. In the D function mode, when the vehicle speed < a and the engine rotational speed < b, it enters the C function mode. In the D function mode, when N>c2, it enters the E function mode.

[0067] As an optional implementation, in response to the air pressure value of the air storage tank in the air supply system satisfying the judgment condition associated with the working mode, a control strategy matching the working mode is determined, including: in response to the working mode being the fifth working mode, determining the judgment condition as the second judgment condition; in response to the air pressure value satisfying the second judgment condition, determining the control strategy as the third control strategy.

[0068] In this embodiment, in the E function mode, the system air supply pressure is X2, and the unloading pressure is Y2. When the air pressure in the air storage tank is lower than X2, the unloading solenoid valve and the regeneration solenoid valve of the air handling unit are both closed, and air filling into the air storage tank starts. When the air pressure in the air storage tank is higher than Y2, the control strategy is determined as the third control strategy: the unloading solenoid valve is opened, air filling into the air storage tank stops, and at the same time the regeneration solenoid valve is opened, and the system regenerates until N≤f2 or the air storage tank pressure is lower than X2 (the maximum regeneration time is no longer restricted).

[0069] Optionally, entering the E function mode does not require vehicle speed or engine speed limitation. In the E function mode, when N≤d2, enter the C or D function mode according to the vehicle speed and engine speed conditions.

[0070] Optionally, in any of the A, B, C, D, and E modes, when the vehicle is powered off and the air storage tank pressure > X3, enter the F function mode. Here, X3 < X1. In the F function mode, the unloading solenoid valve and the regeneration solenoid valve of the air handling unit are opened until the set time t7 is reached. Among them, t7 can be the same as t2 or different from t2.

[0071] Optionally, in any of the A, B, C, D, and E modes, when a system pressure signal fails (at this time, it is impossible to judge which mode to enter), enter the G function mode. In the G function mode, work in a cycle of "the unloading solenoid valve and the regeneration solenoid valve are both closed for t4 - the unloading solenoid valve and the regeneration solenoid valve are both opened for t5 - the unloading solenoid valve is opened and the regeneration solenoid valve is closed for t6" to ensure the basic air supply function of the system.

[0072] Figure 2 It is a schematic diagram of a control logic of an air pressure braking air supply system according to an embodiment of the present application, as Figure 2 shown, according to the two states of engine shutdown and engine operation, the air supply system is divided into 2 major working modes.

[0073] Optionally, as Figure 2 shown, when the engine is shutdown and the N value is not particularly high (less than or equal to d1), it operates in the A mode (which can also be called the default mode), and regeneration is only performed when the N value accumulates to a relatively high level, and the maximum regeneration time is restricted; when the N value is particularly high (greater than or equal to c1), enter the B mode (which can also be called the regeneration mode - pure electric), and regeneration is performed every time unloading occurs in the B mode until the N value drops below the set value or the air storage tank pressure is too low.

[0074] Optionally, as Figure 2 shown, when the engine is running, the vehicle speed is low (less than a) and the engine speed is low (less than b), it operates in mode C. In mode C, regeneration is performed every time there is a load unloading until the value of N drops to a very low level, or the pressure in the air storage tank is too low, or the regeneration time reaches the set maximum regeneration time. When the vehicle speed is relatively high (greater than or equal to a) or the engine speed is relatively high (greater than or equal to b), it operates in mode D. In mode D (which can also be called the energy storage mode), regeneration is performed every time there is a load unloading until the value of N drops to a very low level, or the pressure in the air storage tank is too low, or the regeneration time reaches the set longer maximum regeneration time. When the value of N is relatively high (regardless of the vehicle speed and engine speed status), it operates in mode E (which can also be called the regeneration mode - engine). In mode E, regeneration is performed every time there is a load unloading until the value of N drops to a very low level, or the pressure in the air storage tank is too low. When the vehicle speed and engine speed signals are faulty or lost, it defaults to operating in mode C.

[0075] Optionally, when N ≥ c2, the operating mode is determined to be mode E. In the E function mode, when N is less than or equal to d2, it enters the C or D function mode according to the vehicle speed and engine speed conditions.

[0076] Optionally, in the A function mode, when N ≥ c1, it enters the B function mode. In mode B, when N ≤ d1, it enters mode A.

[0077] Optionally, when the vehicle is powered off and the pressure in the air storage tank is sufficient, regeneration is performed for a fixed period of time.

[0078] Optionally, as Figure 2 shown, in any of the A, B, C, D, E modes, when the vehicle is powered off and the pressure in the air storage tank > X3, it enters the F function mode (flameout regeneration). Here, X3 < X1. In the F function mode, the load unloading solenoid valve and regeneration solenoid valve of the air handling unit are opened until the set time t7 is reached.

[0079] Optionally, as Figure 2 shown, the vehicle's fault information is judged. When the system pressure signal is faulty, the operating condition at this time is a special operating condition, which is the G function mode (which can also be called the safety mode). In this mode, the cycle of "inflation - load unloading and regeneration - load unloading" works.

[0080] Optionally, this embodiment can be slightly modified according to vehicle requirements, such as modifying the X and Y values of a certain mode, combining modes D and E into one, deleting a certain judgment condition of a certain mode, etc.

[0081] In this embodiment, when the vehicle is powered on, the start / stop status of the engine and the gas filtration rate of the dryer are determined. Based on the start / stop status and the gas filtration rate, the operating mode of the gas supply system is determined. Different operating modes are matched with different judgment conditions. Based on the judgment conditions, the current gas supply system is judged to obtain the corresponding control strategy for the gas supply system, thereby achieving the technical effect of reducing the energy consumption of the gas supply system and solving the technical problem of high energy consumption of the gas supply system.
