[0002] Air compressors are a common device used in almost every industry. They are the core equipment of pneumatic systems, converting the mechanical energy of the prime mover (usually an electric motor or diesel engine) into gas pressure energy and providing air power for other equipment.
[0003] Air compressors primarily provide compressed air for braking systems, seats, and other components. Currently, automotive air compressors are driven by the engine's gear system, causing the piston inside the compressor to reciprocate, delivering compressed air to the braking system. As vehicle comfort and economy requirements increase, braking systems become increasingly complex, placing greater demands on air compressor displacement. This, in turn, increases the power consumption of air compressor accessories, which account for a significant portion of engine power. Accurately calculating this power is crucial for throttle response, AMT shifting smoothness, and EBS braking safety.

[0033] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention, as detailed in the appended claims.
[0034] Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. Some of the blocks shown in the drawings are functional entities that do not necessarily correspond to physically or logically separate entities.
[0035] The embodiments of the present application provide a method, device, equipment and storage medium for calculating the accessory work of a vehicle air compressor. By accurately calculating the accessory work of the air compressor, it is possible to respond to the throttle in a timely manner, reduce the vibration, jerking and abnormal noise of the transmission, thereby making the transmission shift smoother, and improve the braking force distribution control and braking comfort, providing higher safety for users.
[0036] It's important to note that engine accessory work is a crucial component of torque path calculation, with the air compressor accessory work accounting for a significant portion. Accurately calculating this component ensures timely throttle response, reduces jerking, jerking, and unusual noise in the AMT, and improves brake force distribution control in the EBS, enhancing braking comfort and safety. Therefore, it plays a crucial role in throttle response, AMT shifting smoothness, and EBS braking safety.
[0037] To achieve the above technical effects, the general ideas of this application are as follows:
[0038] A method for calculating the accessory work of a vehicle air compressor, the method comprising the steps of:
[0039] S101: According to the pressure of the vehicle's air tank, it is determined whether the vehicle's air compressor is currently in an inflation state or an unloading state.
[0040] S102: Calculating the accessory work in the inflated state or the unloaded state, and determining the accessory work of the vehicle air compressor based on the accessory work in the inflated state or the unloaded state.
[0041] The embodiments of the present application are further described in detail below with reference to the accompanying drawings.
[0042] Reference Figure 1 , Figure 1 The figure shows a flow chart of a method for calculating the auxiliary work of a vehicle air compressor provided by the present invention. Figure 1 As shown, the method includes the steps of:
[0043] Step S101: According to the pressure of the vehicle's air tank, determine whether the vehicle's air compressor is currently in an inflation state or an unloading state.
[0044] Specifically, the vehicle's air tank pressure is obtained through the air tank pressure sensor, and the current working state of the vehicle's air compressor is judged based on the obtained air tank pressure. When the vehicle's air tank pressure signal continues to increase within a preset time or the air tank pressure signal is less than the set threshold, it is judged that the vehicle's air compressor is in the inflation state.
[0045] When the vehicle air tank pressure signal continues to decrease within a preset time or the air tank pressure signal is greater than a set threshold, it is determined that the vehicle air compressor is in an unloading state.
[0046] For ease of understanding, an example illustrates this. In one embodiment, the air compressor does not emit signals for its inflation and unloading states, requiring state identification based on the air tank pressure. If the air tank pressure signal value increases continuously over a certain period of time or is less than 960 kPa, the air compressor is in the inflation state. If the air tank pressure signal value decreases continuously over a certain period of time or is greater than 960 kPa, the air compressor is in the unloading state. It should be noted that the "certain period of time" can be understood as at least two cycles, with each cycle consisting of ten collected air tank pressure signal values.
[0047] In one embodiment, the state of the vehicle's air compressor is determined based on the signal values of the air tank pressure sensor during any two consecutive cycles. If, during any two consecutive cycles, the average value of all signal values in the latter cycle is greater than the average value of all signal values in the former cycle, the vehicle's air compressor is determined to be in the inflating state during the two consecutive cycles.
[0048] Optionally, when in any two consecutive cycles, the average value of all signal values in the latter cycle is less than the average value of all signal values in the former cycle, it is determined that the air compressor of the vehicle is in the unloading state in the two consecutive cycles. For easier understanding, an example is given:
[0049] In one embodiment, all signal values of the gas tank pressure sensor within "one cycle for every 10 times" are collected and the average value of all signal values is calculated. Then, a moving average is performed on the signals within two consecutive "one cycle for every 10 times". For ease of understanding, an example is given.
[0050] Calculate the average value P(1) of the signal value in the first "every 10 times as a cycle", calculate the average value P(2) of the signal value in the second "every 10 times as a cycle", and calculate the average value P(1, 2) = P(1) + P(2) / 2 of the signal value in two consecutive cycles.
[0051] Optionally, the average value P(3) of the signal value in the third "every 10 times as a cycle" is calculated, and the average value P(2, 3)=P(2)+P(3) / 2 of the signal value in two consecutive cycles is calculated.
[0052] Optionally, the average value of the signal in the i-th and j-th periods is calculated, P(i, j) = P(i) + P(j) / 2, and the average value of the signal in the j-th and k-th periods is calculated, P(j, k) = P(j) + P(k) / 2.
[0053] When P(j, k)>P(i, j), it is considered that the vehicle air compressor is in the pumping state during the two consecutive cycles.
[0054] When P(j, k) < P(i, j), it is considered that the vehicle air compressor is in an unloading state during the two consecutive cycles.
[0055] It should be noted that the vehicle air compressor has been repeating the cycle of inflation and unloading in the vehicle braking system. When the air compressor fills the air tank to the required working pressure, the air compressor enters the unloading state, which is usually measured in time, that is, the air compressor reaches 75% of the unloading time ratio, and at least 50% of the unloading time ratio.
[0056] Step S102: Calculate the accessory work in the inflated state or the unloaded state, and determine the accessory work of the vehicle air compressor based on the accessory work in the inflated state or the unloaded state.
[0057] In one embodiment, an inflation power consumption curve of the vehicle air compressor is obtained according to the vehicle air tank pressure and the engine speed, and the accessory power of the air compressor in the inflation state is determined by the inflation power consumption curve.
[0058] An unload power consumption curve of the vehicle air compressor is obtained according to the vehicle engine speed and torque, and the accessory work of the air compressor in the unloaded state is determined through the unload power consumption curve.
[0059] After determining whether the vehicle air compressor is currently in the inflating state or the unloading state based on the air tank pressure, if it is in the inflating state, the air compressor accessory work in the inflating state is obtained by checking the air tank pressure and the engine speed. The air compressor accessory work in the inflating state is then used to determine the final accessory work of the vehicle air compressor in the inflating state.
[0060] Because the air compressor has two states (inflated state and unloaded state), if it is not in the inflated state, it means it is in the unloaded state. The power consumption curve of the unloaded state is checked through the engine speed and torque to obtain the air compressor accessory work in the unloaded state. The final accessory work of the vehicle air compressor in the unloaded state is determined through the air compressor accessory work in the unloaded state.
[0061] It should be noted that the accessory work of the air compressor differs significantly between the inflated and unloaded states. Therefore, the calculation of the air compressor accessory work needs to be divided into two types according to the different states: the inflated state and the unloaded state. The inflated state's accessory work is related to the speed and air tank pressure, while the unloaded state's accessory work is related to the speed and torque.
[0062] Reference Figure 2 , Figure 2 FIG. 1 is a schematic diagram of a vehicle air compressor accessory work calculation device provided by the present invention, as shown in FIG. Figure 2 As shown, the device includes:
[0063] The judgment module 201 is used to judge whether the vehicle air compressor is currently in the inflation state or the unloading state according to the pressure of the vehicle air tank.
[0064] The determination module 202 is configured to calculate the accessory work in the inflated state or the unloaded state, and determine the accessory work of the vehicle air compressor based on the accessory work in the inflated state or the unloaded state.

[0066] When the pressure value of the vehicle's air tank continues to decrease within a preset time or is greater than a set threshold, it is determined that the vehicle's air compressor is currently in an unloading state.
[0067] Furthermore, in a possible implementation, the judgment module 201 is further configured to, when in any two consecutive cycles, the average value of all signal values in the latter cycle is greater than the average value of all signal values in the former cycle, determine that the air compressor of the vehicle is in the inflating state in the two consecutive cycles;
[0068] When, in any two consecutive cycles, the average value of all signal values in the latter cycle is less than the average value of all signal values in the former cycle, it is determined that the air compressor of the vehicle is in an unloading state in the two consecutive cycles.
[0069] Furthermore, in a possible implementation manner, the set threshold is 960 kPa;
[0070] Every 10 times the pressure signal value of the gas storage tank is collected is one cycle.
[0071] Furthermore, in a possible implementation, the determination module 202 is further configured to obtain an air-inflating power consumption curve of the vehicle air compressor according to the vehicle air tank pressure and the engine speed, and determine the accessory power of the air compressor in the inflating state through the air-inflating power consumption curve;
[0072] An unload power consumption curve of the vehicle air compressor is obtained according to the vehicle engine speed and torque, and the accessory work of the air compressor in the unloaded state is determined through the unload power consumption curve.
