[0002] Hybrid vehicles are vehicles that are powered by both an engine and a battery. The energy requirements of a hybrid vehicle, which consists of a chassis and a superstructure, differ significantly between normal driving conditions and superstructure operation conditions. Therefore, it is necessary to coordinate the energy of the chassis and superstructure of a hybrid vehicle.

[0003] Traditional methods for coordinating energy distribution between the chassis and superstructure of a hybrid vehicle first require obtaining the energy usage of the superstructure and chassis. The chassis energy usage can be obtained through the CAN network within the hybrid vehicle, while the superstructure energy usage is often obtained by adding a current measuring device to obtain the superstructure current value. The superstructure current value is then used for calculation, and energy is then coordinated and distributed based on the energy usage of the superstructure and chassis.

[0020] The power generation of the engine is obtained based on the proportional coefficient and the average power consumption of the superstructure, wherein the average power consumption is equal to the energy consumption value divided by the preset duration.

[0021] In one embodiment, obtaining the engine's power generation capacity based on the proportionality coefficient and the average power consumption of the superstructure includes:

[0022] The power generation capacity of the engine is obtained by multiplying the proportional coefficient by the average power consumption of the superstructure.

[0026] The first determining module is used to determine the second current value of the upper device based on the total current value and the first current value;

[0027] The second determining module is used to determine the energy consumption value of the upper device within a preset time period based on the second current value.

[0028] Thirdly, this application also provides a computer device. The computer device includes a memory and a processor, the memory storing a computer program, and the processor executing the computer program to implement the steps of any of the methods described above.

[0039] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0040] In this embodiment, a method for obtaining energy from the superstructure of a hybrid vehicle is provided. This embodiment uses the application of this method to a computer device as an example for illustration. It can be understood that this method can also be applied to a server, and can also be applied to a system including a computer device and a server, and can be implemented through the interaction between the computer device and the server.

[0041] Figure 1 This is a flowchart illustrating the energy harvesting method for a hybrid vehicle's superstructure provided in this application embodiment. The method is applied to a computer device or server. In one embodiment, such as... Figure 1 As shown, it includes the following steps:

[0042] S101, obtain the total current value of the hybrid vehicle, wherein the total current value is the current value obtained by using the same power battery to power the superstructure and chassis of the hybrid vehicle.

[0043] Hybrid vehicles refer to vehicles whose drive systems consist of two or more individual drive systems that can operate simultaneously. The vehicle's driving power is provided individually or jointly by the individual drive systems depending on the actual driving conditions. Hybrid vehicles can be gasoline-electric hybrid vehicles, which use an engine (diesel or gasoline engine) and a power battery as power sources. Some engines are modified to use other alternative fuels, such as compressed natural gas, propane, and ethanol fuel. The superstructure refers to other assemblies installed on hybrid vehicles, such as the tank body of a tank mixer truck or the cargo box of a van. The chassis refers to the combination of the transmission system, running system, steering system, and braking system on a hybrid vehicle.

[0044] The hybrid vehicle in this embodiment includes, but is not limited to, sweepers, water trucks, and vehicles with hybrid power and a superstructure. The hybrid vehicle has a CAN network, which is used in computer equipment or servers. The CAN network can obtain the total current value, chassis current value, and state of charge of the power battery.

[0045] S102, obtain the first current value of the chassis.

[0046] In this embodiment, the same power battery is used to power the superstructure and chassis of the hybrid vehicle. Specifically, it can be done according to... Figure 2 The power distribution method shown is as follows: Figure 2 This is a schematic diagram of power distribution in a hybrid vehicle provided in this embodiment. Figure 2 The PDU in this context refers to the power distribution unit, which distributes the electricity generated by the power battery to the chassis and superstructure. The electricity generated by the power battery is distributed to the superstructure and chassis. The chassis power supply includes low-voltage and high-voltage power. Low-voltage power supply includes the power supply of various controllers on the chassis, the various parts of the low-voltage power supply on the chassis, and the headlight power supply. High-voltage power supply includes the power supply of the drive motor, the air conditioning, and other high-voltage power supplies on the chassis. In other words, all the power supply that belongs to the chassis components belongs to the chassis power supply, and all the power supply that belongs to the superstructure components belongs to the superstructure power supply.

[0047] S103, determine the second current value of the upper device based on the total current value and the first current value.

[0048] In this embodiment, the second current value of the upper device can be determined based on the total current value and the first current value in the following manner:

[0049] The second current value of the upper device can be achieved by multiplying the difference between the total current value and the first current value by a preset error coefficient, or by multiplying the first current value by a preset current coefficient to obtain the current result, and then using the difference between the total current value and the current result as the second current value of the upper device.

[0050] S104, determine the energy consumption value of the upper device within a preset time period based on the second current value.

[0051] In this embodiment, the energy consumption value of the upper device within a preset time period can be determined based on the second current value in the following manner:

[0052] It can obtain the instantaneous power of the device at a certain moment within a preset time period, and then use the instantaneous power multiplied by the preset time period to obtain the energy consumption value of the device.

[0053] The aforementioned method for harvesting energy from the superstructure of a hybrid vehicle supplies power to both the superstructure and chassis using the same battery. It obtains the total current value of the hybrid vehicle and a first current value from the chassis. Based on these two values, a second current value for the superstructure is determined, and then the energy consumption of the superstructure within a preset time period is determined based on this second current value. Traditional methods require additional current measuring equipment to obtain the superstructure's current value, and then use that current value to calculate the energy consumption. However, this embodiment directly obtains the second current value from the total current value and the first current value from the chassis, eliminating the need for additional current measuring equipment and thus solving the problem of the complex process involved in obtaining the superstructure's energy value.

[0054] In an embodiment of this application, step S103 includes:

[0055] The difference between the total current value and the first current value is used as the second current value of the upper device.

[0056] In this embodiment, the second current value of the superstructure is obtained by formula (1), which is shown below:

[0057] I 上 =I 总 -I 底 =I 总 -(I1+I2+I3+…+I n (1)

[0058] Among them, I 上 Indicates the second current value of the upper device, I 总 I represents the total current value of a hybrid vehicle. 底 This represents the first current value of the chassis, which is equal to the sum of the electrical consumption of all parts of the chassis, I1, I2, I3, ..., I... n This indicates the power consumption of each part of the chassis.

[0059] In this embodiment, the total current value and the current values ​​of each part of the chassis can be obtained through the CAN network or through the controllers installed on the chassis, thereby obtaining the current value of the superstructure. There is no need to add current measuring equipment, which can reduce costs and is applicable to all hybrid vehicles.

[0060] In another embodiment, step S103 further includes:

[0061] The difference between the total current value and the first current value is multiplied by a preset error coefficient to obtain the second current value of the upper device.

[0062] Similarly, using the method in this embodiment to obtain the second current value of the superstructure can reduce costs, improve accuracy, and is applicable to all hybrid vehicles.

[0063] In the embodiments of this application, step S104 can be implemented in the following manner:

[0064] The energy consumption value of the upper device is obtained by integrating the second current value over a preset duration.

[0065] In this embodiment, the energy consumption value of the superstructure is obtained through formula (2), which is shown below:

[0066]

[0067] Among them, W 上 P represents the energy consumption value of the superstructure. 上 Indicates the power of the superstructure, I 上 R represents the second current value of the upper device. 上 The resistance value of the upper component can be obtained via the CAN network. (U) 上 The voltage value of the superstructure is equal to the voltage value of the power battery and the voltage value of the chassis. It can be obtained through the CAN network. t1 represents the start time of the preset duration, and t2 represents the end time of the preset duration.

[0068] In this embodiment, the integral value of the power of the upper device within a preset time period is used instead of the instantaneous power at a certain moment. This avoids sudden changes in the power signal and cancels out the error of the current signal in the time dimension, ensuring the accuracy of the energy consumption value of the upper device. This improves the accuracy of the calculation and avoids the impact of sudden changes in the power value of the upper device.

[0069] In one embodiment, after determining the energy consumption value of the upper device within a preset time period based on the second current value in S104 above, the following steps may also be included:

[0070] If the energy consumption value is greater than the preset energy consumption threshold, the engine's power generation is determined so that the engine can use the power generation to supply power to the power battery. The preset energy consumption threshold is a threshold determined based on the current state of charge of the power battery.

[0071] In this embodiment, the reason why the engine supplies power to the battery is to ensure that the state of charge of the battery is always kept within a healthy range, such as keeping the SOC value of the battery at 60%-70%. This can avoid overcharging and over-discharging of the battery and help extend its service life.

[0072] The preset energy consumption threshold is determined based on the current state of charge of the power battery. The higher the current state of charge of the power battery, the higher the preset energy consumption threshold; the lower the current state of charge of the power battery, the lower the preset energy consumption threshold.

[0073] Specifically, the preset energy consumption threshold can be determined in the following ways: Figure 3 As shown, Figure 3 This is a schematic diagram illustrating the correspondence between a preset energy consumption threshold determination method provided in an embodiment of this application. Figure 3 The horizontal axis represents the SOC value, which is the state of charge of the power battery, and the vertical axis represents the P value. 平均 That is, the average power, with a preset energy consumption threshold equal to P. 平均 Multiply by the preset duration, from Figure 3 It is not difficult to see that as the state of charge (SOC) of the power battery decreases, the average power P... 平均 The lower the threshold, the more energy needs to be replenished because a lower state of charge of the power battery means a lower state of charge. Therefore, the threshold should be lowered to ensure that the power battery can be compensated. Figure 3 In the middle, when the state of charge of the power battery is 70%, P 平均 The value is selected from 1.8KW to 2.1KW. For example, if 2KW is selected, multiplying 2KW by the preset duration of 1 hour equals the preset energy consumption threshold of 2KWh. When the state of charge of the power battery is 30%, P 平均 The value can be selected from 0.3KW to 0.6KW. For example, if we select 0.5KW, multiplying 0.5KW by the preset duration of 1 hour will equal the preset energy consumption threshold of 0.5KWh.

[0074] The SOC value indicates the amount of remaining power in the battery. A higher SOC value means more remaining power, while a lower SOC value means less remaining power.

[0075] Figure 4 This is a flowchart illustrating a method for determining the power generation capacity of an engine provided in an embodiment of this application. (Refer to...) Figure 4 This embodiment relates to one method for determining the engine's power generation capacity to compensate for the power battery's charge. Based on the above embodiment, determining the engine's power generation capacity includes the following steps:

[0076] S401 determines the current state of charge of the power battery.

[0077] In this embodiment, the current state of charge (SOC) of the power battery can be obtained through the CAN network within the hybrid vehicle.

[0078] S402, determine the proportional coefficient corresponding to the current state of charge based on the preset correspondence and the current state of charge. The preset correspondence includes the correspondence between different states of charge of the power battery and different preset proportional coefficient ranges.

[0079] In this embodiment, the method for determining the scaling factor can be as follows: Figure 5 As shown, Figure 5 This is a schematic diagram illustrating the correspondence of a proportional coefficient determination provided in an embodiment of this application. Figure 5 The horizontal axis represents the SOC value, which is the current state of charge of the power battery, and the vertical axis represents K, which is the proportional coefficient. Figure 5 It is not difficult to see that as the SOC value increases, the proportional coefficient becomes smaller. This is because an increase in the SOC value means that there is more remaining charge in the power battery, so less charge needs to be replenished by the engine. Therefore, a smaller proportional coefficient is needed to keep the SOC value stable within the ideal range, such as 60% to 70%. Keeping the SOC value of the power battery stable within the ideal range helps to extend the service life of the power battery. Figure 5 In this context, when the state of charge of the power battery is 30%, the proportional coefficient ranges from 4.9 to 5.1; when the state of charge of the power battery is 70%, the proportional coefficient ranges from 1.4 to 1.8.

[0080] S403, the engine's power generation is obtained based on the proportional coefficient and the average power consumption of the superstructure, where the average power consumption is equal to the energy consumption value divided by the preset duration.

[0081] In this embodiment, the engine's power generation is determined so that the engine can use the power generation to supply power to the power battery. The proportional coefficient is dynamically adjusted according to the power battery's SOC value. The engine's power generation is obtained based on the proportional coefficient and the average power consumption of the superstructure. This enables dynamic energy compensation for the power battery, improves the power battery's lifespan, and further ensures the performance of the hybrid vehicle.

[0082] In the embodiments of this application, step S403, obtaining the engine's power generation capacity based on the proportional coefficient and the average power consumption of the superstructure, can be achieved in the following way:

[0083] Multiply the proportional coefficient by the average power consumption of the above-mentioned equipment to obtain the engine's power generation capacity.

[0084] In this embodiment, the power generation of the engine is obtained by formula (3), which is shown below:

[0085]

[0086] Among them, P 发电 Where P is the generator output power of the engine, K is the proportional coefficient, and P is the generator output power of the engine. 上平均 This represents the average power consumption of the upper structure.

[0087] In another embodiment, step S403, obtaining the engine's power generation capacity based on the proportional coefficient and the average power consumption of the superstructure, can also be achieved in the following way:

[0088] The generator output power is obtained by multiplying the proportional coefficient by the average power consumption of the above-mentioned equipment and adding the result to the preset correction constant.

[0089] It should be noted that, as can be seen from the above formula (3), in P 上平均 Under certain conditions, the smaller the proportional coefficient, the smaller the power generation of the engine. Therefore, when a smaller proportional coefficient is needed to keep the SOC value stable in the ideal range, it is not only beneficial to extend the service life of the power battery, but also to save fuel resources required for the engine to generate electricity.
