[0030] Example 1
[0031] Figure 1A This is a flowchart of a braking system optimization method provided in Embodiment 1 of the present invention. This embodiment is applicable to optimizing the braking system of pure electric vehicles. The method can be executed by a braking system optimization device, which can be implemented in hardware and / or software. This device can be configured in an electronic device, which can be a software simulation platform, such as the AMESim simulation platform. Figure 1AAs shown, the method includes:
[0032] S101. Create a virtual braking system based on the component connection relationships of the actual braking system of the target pure electric vehicle.
[0033] The target pure electric vehicle refers to a real pure electric vehicle whose braking system component parameters require adjustment. The real braking system refers to the actual braking system of the target pure electric vehicle. Components refer to the parts that make up the real braking system of the target pure electric vehicle, and may include compressors, air tanks, pressure sensors, compressor pumps, air supply lines, or control lines, etc. Component connection relationships refer to the connection relationships between components in the real braking system. The virtual braking system refers to a virtual braking system obtained by simulating the real braking system.
[0034] Optionally, the components of a virtual braking system can be constructed based on the components of the actual braking system of the target pure electric vehicle, and the connection relationships between the components in the virtual braking system can be drawn according to the connection relationships of the components in the actual braking system of the target pure electric vehicle. For example, a virtual braking system can be created based on the component connection relationships of the actual braking system of the pure electric vehicle using a software simulation platform. The software simulation platform is specifically designed to simulate real computer software and can be the AMESim simulation platform. The AMESim simulation platform is used for complex system modeling and simulation in multidisciplinary fields.
[0035] Specifically, based on the components of a real braking system provided by the AMESim software simulation platform, the components of a virtual braking system can be constructed. Then, following the connection relationships of the components in the real braking system, the connection relationships between the components in the virtual braking system can be drawn. For example, such as... Figure 1B As shown, outside air 1 is connected to compressor pump 2. Compressor pump 2 is connected to air storage tank 3 and pressure sensor 4 respectively. Air storage tank 3 is connected to pressure sensor 4. Pressure sensor 4 is connected to brake pedal and control signal input 5. Brake pedal and control signal input 5 is connected to brake pedal and control signal input 6. Brake pedal and control signal input 6 is connected to brake chamber system.
[0036] S102. Based on the working logic of the air pump in the real braking system, the working process of the virtual braking system is simulated to obtain the target air pressure change in the virtual air tank of the virtual braking system.
[0037] The air pump's operating logic controls its operation based on the actual pressure value within the air reservoir. Specifically, if the real-time pressure value in the air pump is less than a first pressure value, the air pump operates; if the real-time pressure value is greater than a second pressure value, the air pump does not operate. The first and second pressure values can be set according to actual conditions; for example, the first pressure value could be 0.7 MPa, and the second pressure value could be 1 MPa.
[0038] Among them, the change in target air pressure refers to the increase or decrease in target air pressure in the virtual air storage tank after the virtual braking system brakes.
[0039] Specifically, based on the working logic of the air pump in a real braking system, the working process of the virtual braking system is simulated. That is, based on the AMESim simulation platform, the virtual braking system simulates the working principle of the air pump in the real braking system of a pure electric vehicle, supplying air into a virtual air reservoir. The air pump's operation is controlled by changing the target air pressure within the virtual air reservoir. When the air pump is working, the target air pressure within the reservoir will rise or fall accordingly. At this time, the change curve of the target air pressure within the virtual air reservoir can be plotted on the AMESim simulation platform to obtain the target air pressure variation within the virtual air reservoir.
[0040] S103. Based on the changes in target air pressure, verify the component parameters of the actual braking system.
[0041] Here, component parameters refer to the relevant information marked on the components in the actual braking system. For example, a compressor might have parameters such as compressor displacement and compressor model.
[0042] Specifically, the target number of braking operations can be determined based on the target air pressure changes, and the component parameters in the actual braking system can be checked based on the target number of braking operations. For example, the target number of braking operations can be determined based on the number of times the target air pressure change curve decreases; based on the target number of braking operations, it can be determined whether the component parameters in the actual braking system are appropriate.
[0043] The technical solution of this invention first creates a virtual braking system based on the component connection relationships of the actual braking system of the target pure electric vehicle. Then, based on the working logic of the air pump in the actual braking system, the working process of the virtual braking system is simulated to obtain the target air pressure changes within the virtual air reservoir. Finally, based on these target air pressure changes, the component parameters in the actual braking system are checked. Compared to existing methods based on empirical estimation for selecting braking system components, this invention, through the simulation of the actual braking system and its working process of a pure electric vehicle, more closely resembles real-world operating conditions and improves the accuracy of component selection and matching in the actual braking system.
[0044] Based on the above embodiments, as an optional embodiment of the present invention, after creating a virtual braking system according to the component connection relationship of the real braking system of the target pure electric vehicle, the component parameters of the virtual braking system can also be configured according to the component parameters of the real braking system.
[0045] The component parameters refer to the configuration parameters of the components in the actual braking system, which may include at least one of the following: air reservoir pressure, air reservoir volume, compressor pump speed, and compressor displacement. Specifically, air reservoir pressure refers to the pressure of the gas inside the air reservoir; compressor pump speed refers to the number of revolutions the compressor pump makes around the center of a circle per unit time; and compressor displacement refers to the amount of gas continuously delivered by the compressor.
[0046] Specifically, the component parameters of the virtual braking system can be configured accordingly based on the component parameters of the real braking system.
[0047] The above technical solution ensures a one-to-one correspondence between the virtual braking system and the real braking system of the target pure electric vehicle, realizing the simulation of the real braking system and its working process of the pure electric vehicle.
[0048] Example 2
[0049] Figure 2A This is a flowchart of a braking system optimization method provided in Embodiment 2 of the present invention. Based on the above embodiments, this embodiment further optimizes the step of "simulating the working process of a virtual braking system according to the working logic of the air pump in a real braking system, and obtaining the target air pressure change in the virtual air reservoir of the virtual braking system," providing an optional implementation scheme. For example... Figure 2A As shown, the method includes:
[0050] S201. Create a virtual braking system based on the component connection relationships of the actual braking system of the target pure electric vehicle.
[0051] S202. Simulate the real external air input value and input the external air input value into the compressor air pump of the virtual braking system.
[0052] The external air input value refers to the simulated actual air input value of the compressor pump.
[0053] Specifically, the system simulates real external air input values and inputs these values into the compressor pump of the virtual braking system, thus simulating real operating conditions and inputting air into the compressor pump. After processing by the compressor pump, the processed air values are input into the air storage tank of the virtual braking system, thus sending air into the air storage tank. The pressure sensor in the virtual braking system collects the air pressure value of the air storage tank.
[0054] S203. Based on the working logic of the air pump in the real braking system, the working process of the virtual braking system is simulated to obtain the target air pressure change in the virtual air tank of the virtual braking system.
[0055] Specifically, according to the operating logic of the compressor air pump in the actual braking system, if the pressure value in the compressor air pump is less than a first pressure value, the air pump operates; if the pressure value in the compressor air pump is greater than a second pressure value, the air pump does not operate. The first and second pressure values can be set according to actual conditions; for example, the first pressure value could be 0.7 MPa, and the second pressure value could be 1 MPa.
[0056] S204. Based on the changes in target air pressure, verify the component parameters of the actual braking system.
[0057] The technical solution of this invention creates a virtual braking system based on the component connection relationships of the actual braking system of a target pure electric vehicle. Then, it simulates the actual external air input value and inputs this value into the compressor pump of the virtual braking system. Subsequently, based on the pump's operating logic in the actual braking system, it simulates the operation of the virtual braking system to obtain the target air pressure changes within the virtual air reservoir. Finally, based on these target air pressure changes, it verifies the component parameters of the actual braking system. This technical solution, by further simulating the external air input value of the actual braking system, further improves the accuracy of simulating the actual braking system and its operation process of a pure electric vehicle.
[0058] Based on the above embodiments, as an optional aspect of the present invention, the component parameters of the actual braking system are checked according to the target air pressure change. This can be achieved by: determining the virtual actual number of braking operations based on the target air pressure change; and checking the component parameters of the actual braking system based on the actual number of braking operations and the theoretical number of braking operations.
[0059] Here, "actual braking count" refers to the number of braking maneuvers a virtual target pure electric vehicle can achieve under actual operating conditions, as determined by the virtual braking system. For example, such as... Figure 2B As shown, when the target air pressure does not meet the braking conditions, i.e. Figure 2B Between the points where the target air pressure transitions from decreasing to gradually increasing, the number of virtual actual braking operations can be determined by counting the number of times the target air pressure decreases between these points. Each decrease in target air pressure between these points represents one braking operation by the virtual system. Figure 2B In the meantime, the target air pressure dropped a total of 12 times between that point, which means the virtual actual braking number was 12.
[0060] The theoretical number of braking cycles refers to the maximum number of braking cycles that the target pure electric vehicle can theoretically achieve. For example, it can be obtained through the following formula.
[0061]
[0062] Where n represents the number of consecutive braking cycles (the state where the air pump stops working), P1 represents the lowest absolute pressure of air in the air reservoir, P represents the highest absolute pressure of air in the air reservoir, and V s V represents the volume of the air chamber filled with air. g 1 represents the total volume of the gas supply pipeline, V g 2 represents the total volume of the control pipeline, V c This indicates the total volume of the gas storage tank.
[0063] Specifically, the actual number of braking actions can be compared with the theoretical number of braking actions. Based on the comparison results, it can be determined whether the component parameters in the actual braking system are accurate. For example, if the actual number of braking actions is greater than the theoretical number of braking actions, it indicates that the component parameters in the actual braking system are not compatible, which may be due to an insufficient air reservoir volume.
[0064] Understandably, by comparing the actual number of braking operations with the theoretical number of braking operations, the parameters of the components in the real braking system can be checked, and it can be verified whether the parameters of the components in the real braking system are appropriate.
[0065] Based on the above embodiments, as an optional embodiment of the present invention, after verifying the component parameters in the actual braking system according to the target air pressure change, the components in the actual braking system can also be adjusted according to the verification results.
[0066] Specifically, if the actual number of braking actions equals the theoretical number of braking actions in the verification results, it means that the model of the components selected for the actual braking system is appropriate and no adjustment of the components is required; if the actual number of braking actions is greater than or less than the theoretical number of braking actions, it means that the model of the components selected for the actual braking system is inappropriate and the model of the components needs to be adjusted, such as by changing the model of the components.
[0067] The above technical solution, after verifying the component parameters in the actual braking system based on the target air pressure change, adds adjustments to the components in the actual braking system based on the verification results, making the entire verification process more complete and providing specific solutions after verification. While simulating the actual working conditions of pure electric vehicles, it further improves the accuracy of component selection and matching in the actual braking system.
