[0094] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0095] Based on the problems mentioned in the above background technology, in the related art, the semi-active stabilizer bar system adjusts the hydraulic damping through the solenoid valve, but this method can only achieve the damping adjustment of the stabilizer bar, resulting in a monotonous function of the stabilizer bar.

[0096] To address the aforementioned issues, embodiments of the present application provide a stabilizer bar power generation system, control method, device, medium, product, and vehicle. The stabilizer bar power generation system provided in embodiments of the present application includes a stabilizer bar, which, when moved, drives fluid to flow within a fluid conduit; a fluid conduit equipped with an opening regulating valve for regulating the flow of fluid within the conduit; and a power generation module, connected to the fluid conduit, that generates electricity based on the flow of fluid within the conduit. Energy from the stabilizer bar can be recovered, enabling the stabilizer bar's power generation function.

[0097] Specifically, the stabilizer bar power generation system of the present application can be installed on a vehicle or other equipment and can be connected to the vehicle's suspension to maintain vehicle stability. The following uses the stabilizer bar power generation system installed on a vehicle as an example to describe various embodiments in detail.

[0098] This application provides a stabilizer bar power generation system 100, please refer to Figure 1 The stabilizer bar power generation system provided in the embodiment of the present application includes:

[0099] A stabilizing rod 10, wherein the stabilizing rod 10 drives the fluid to flow in the fluid conduit when the stabilizing rod 10 is in motion;

[0100] A fluid pipeline 20 is provided with an opening regulating valve 21 , and the opening regulating valve 21 is used to regulate the flow of the fluid in the fluid pipeline 20 ;

[0101] The power generation module 30 is in communication with the fluid pipeline 20 , and generates electricity based on the flow of fluid in the fluid pipeline 20 .

[0102] In this embodiment, the stabilizer bar 10 is connected to the vehicle's suspension. When the vehicle turns, centrifugal force causes the vehicle body to roll. For example, when the vehicle turns left, the right side of the vehicle body lifts up, while the left side tilts down. The stabilizer bar is connected to the suspension via connecting rods at both ends. When the vehicle body rolls, the suspension on one side moves upward, while the suspension on the other side moves downward. This movement of the stabilizer bar reduces vehicle body roll during cornering, improving vehicle handling stability and ride comfort.

[0103] In this embodiment, the stabilizer bar power generation system 100 also includes a fluid pipeline 20. The structure between the fluid pipeline 20 and the stabilizer bar 10 can enable the stabilizer bar 10 and the fluid in the fluid pipeline 20 to be linked. When the stabilizer bar 10 moves, it will drive the fluid to flow in the fluid pipeline 20, thereby generating hydraulic energy and providing damping for the movement of the stabilizer bar 10.

[0104] In this embodiment, an opening regulating valve 21 is provided on the fluid pipeline 20. The opening of the opening regulating valve 21 can be adjusted by automatic, manual or other control operations. The opening regulating valve 21 can be a solenoid valve, such as a proportional solenoid valve, etc., and its opening can be changed by a control signal, so as to limit the flow in the fluid pipeline 20, change the hydraulic pressure, flow rate, etc. in the fluid pipeline 20, so that the damping of the stabilizer bar can be adjusted through the opening regulating valve 21, and the damping control of the stabilizer bar 10 is realized, so that the stabilizer bar 10 can better adapt to the driving environment of the vehicle and further improve the vehicle comfort.

[0105] In this embodiment, the stabilizer bar power generation system 100 also includes a power generation module, a power generation module 30. The power generation module 30 is connected to the fluid pipeline 20. The flow of fluid in the fluid pipeline 20 generates hydraulic energy, which can drive the power generation module 30. The power generation module 30 generates electricity based on the flow of fluid in the fluid pipeline 20 to recover the energy of the stabilizer bar 10 when it is active, thereby realizing the power generation function based on the drive of the stabilizer bar 10, and the opening regulating valve 21 set on the fluid pipeline 20 can adjust the flow of fluid in the fluid pipeline 20, thereby adjusting the hydraulic energy that can be provided to the power generation module 30 to adjust the power generation power of the power generation module 30.

[0106] Since power generation requires continuous fluid flow, while damping regulation requires flow rate restriction, the two are generally difficult to coordinate. Therefore, damping control and power generation control are generally relatively separated, and the damping and power generation of the stabilizer bar are adjusted independently, resulting in response delays and energy losses. This problem is overcome by the embodiments of the present application. The system provided by the embodiments of the present application can coordinate damping regulation and power generation regulation, reducing response delays and energy losses.

[0107] In one embodiment, the power generation module 30 includes a hydraulic motor 31 and a generator connected to the hydraulic motor 31; the hydraulic motor 31 is connected in series in the fluid pipeline 20, and drives the generator to generate electricity based on the flow of fluid in the fluid pipeline 20.

[0108] In an embodiment, the power generation module 30 includes a hydraulic motor 31 and a generator (not shown in the figure) connected to the hydraulic motor 31. The hydraulic motor 31 is connected in series in the fluid pipeline 20, so that the power generation module 30 is connected to the fluid pipeline 20. When the fluid in the fluid pipeline 20 flows through the hydraulic motor 31, the hydraulic motor 31 converts the hydraulic energy of the fluid flow into mechanical energy, and drives the generator connected to the hydraulic motor 31 to generate electricity, thereby recovering the energy of the stabilizer bar 10 driving the fluid flow, thereby realizing the power generation function.

[0109] In one embodiment, the stabilizer bar power generation system 100 further includes:

[0110] The cylinder body 40 has a liquid cavity therein, a piston 41 is provided in the liquid cavity, the fluid pipeline 20 is connected to the liquid cavity, and the piston 41 is connected to the stabilizing rod 10. When the stabilizing rod 10 moves, it drives the piston 41 to move in the liquid cavity, so that the fluid flows in the liquid cavity and the fluid pipeline 20.

[0111] In this embodiment, the stabilizer bar power generation system 100 also includes a cylinder 40. The cylinder 40 is hollow, forming a cavity that can accommodate a fluid, that is, a liquid chamber within the cylinder 40. The fluid can be an incompressible fluid, such as oil, commonly found on vehicles, which can provide hydraulic pressure to achieve damping and power generation. A fluid conduit 20 is connected to the liquid chamber, and a piston 41 is also disposed within the liquid chamber. The piston 41 is directly or indirectly connected to the stabilizer bar 10. In some embodiments, the stabilizer bar 10 can be a rigid pair of arms on either side of the piston, or can be connected to the piston 41 via rigid arms on either side of the piston, so that when the stabilizer bar 10 moves, it drives the piston 41 to move within the liquid chamber. The movement of the piston 41 can drive the fluid in the liquid chamber to flow into the fluid conduit 20, thereby allowing the fluid to flow within the liquid chamber and the fluid conduit 20. This simple power generation oil circuit structure eliminates the need for an external power source. The movement of the stabilizer bar 10 drives the piston 41 to directly drive the fluid flow for power generation, thereby improving power generation efficiency and reducing system costs.

[0112] In one embodiment, the piston 41 divides the liquid chamber into a first chamber 42 and a second chamber 43 , wherein the first chamber 42 is connected to one end of the fluid conduit 20 , and the second chamber 43 is connected to the other end of the fluid conduit 20 .

[0113] In this embodiment, the piston 41 can divide the liquid chamber into a first chamber 42 and a second chamber 43. The fluid pipeline 20 has at least two ports. The first chamber 42 is connected to one end of the at least two ports of the fluid pipeline 20, and the second chamber 43 is connected to the other end of the at least two ports of the fluid pipeline 20, so that the first chamber 42 and the second chamber 43 are respectively connected to different ports of the fluid pipeline 20, so that a hydraulic circuit can be formed, and the piston 41 can move in both directions in the liquid chamber. In this way, when the stabilizer bar 10 drives the piston 41 to move in any direction, it can cause the fluid to flow in the liquid chamber and the fluid pipeline 20, thereby achieving damping in different directions and further improving the power generation efficiency.

[0114] In one embodiment, the first cavity 42 is provided with a first pressure sensor 44 , and the second cavity 43 is provided with a second pressure sensor 45 .

[0115] In this embodiment, the first cavity 42 is provided with a first pressure sensor 44 for collecting the hydraulic pressure in the first cavity 42, and the second cavity 43 is provided with a second pressure sensor 45 for collecting the hydraulic pressure in the second cavity 43, which can be used for subsequent specific control and adjustment.

[0116] In one embodiment, the first pressure sensor 44 is used to collect the hydraulic pressure of the first cavity 42 , and the second pressure sensor 45 is used to collect the hydraulic pressure of the second cavity 43 to determine the hydraulic pressure difference on both sides of the hydraulic motor 31 and / or the hydraulic pressure difference on both sides of the piston 41 .

[0117] In this embodiment, the hydraulic pressure of the first chamber 42 collected by the first pressure sensor 44 and the hydraulic pressure of the second chamber 43 collected by the second pressure sensor 45 can be used to determine the hydraulic pressure difference on both sides of the hydraulic motor 31 and / or the hydraulic pressure difference on both sides of the piston 41 for subsequent specific control and adjustment.

[0118] In some embodiments, due to the connectivity of the fluid channel, the hydraulic difference between the hydraulic pressure of the first chamber 42 and the hydraulic pressure of the second chamber 43 can be used as the hydraulic pressure difference on both sides of the hydraulic motor 31 and the hydraulic pressure difference on both sides of the piston 41, that is, the hydraulic pressure difference on both sides of the hydraulic motor 31 and the hydraulic pressure difference on both sides of the piston 41 can be the same.

[0119] In one embodiment, the fluid pipeline 20 includes a first pipeline segment 1, a second pipeline segment 2, and a third pipeline segment 3. The first end of the first pipeline segment 1 is connected to the first cavity 42, and the first end of the second pipeline segment 2 is connected to the second cavity 43.

The second end of the third pipe segment 3 is connected to the first cavity 42 and the second cavity 43 respectively.

[0121] In this embodiment, the fluid pipeline 20 includes a first pipeline segment 1, a second pipeline segment 2, and a third pipeline segment 3. The first end of the first pipeline segment 1 communicates with the first cavity 42, and the first end of the second pipeline segment 2 communicates with the second cavity 43, such that the first cavity 42 communicates with one end of the fluid pipeline 20, and the second cavity 43 communicates with the other end of the fluid pipeline 20. The second ends of the first pipeline segment 1, the second ends of the second pipeline segment 2, and the first end of the third pipeline segment 3 are interconnected. The opening regulating valve 21 is disposed on the third pipeline segment 3, and the hydraulic motor 31 is connected in series to the third pipeline segment 3. The second end of the third pipeline segment 3 communicates with the first cavity 42 and the second cavity 43, respectively, and the second end of the third pipeline segment 3 communicates with the first cavity 42 and the second cavity 43, respectively. This ensures that when the stabilizer bar 10 drives the piston 41 in bidirectional motion, fluid can return to both the first cavity 42 and the second cavity 43 through the third pipeline segment 3, thereby driving the hydraulic motor 31 to generate electricity.

[0122] In one embodiment, a first one-way valve 6 is provided on the first pipe section 1 so that the fluid in the first cavity 42 can flow to the third pipe section 3 through the first one-way valve 6;

[0123] A second one-way valve 7 is provided on the second pipeline section 2 , so that the fluid in the second cavity 43 can flow to the third pipeline section 3 through the second one-way valve 7 .

[0134] In one embodiment, a plurality of the opening regulating valves 21 are provided in the third pipeline section 3 .

[0135] In this embodiment, there can be multiple opening regulating valves 21 in the system. Multiple opening regulating valves 21 can be set on the third pipeline section 3 to prevent the failure of one opening regulating valve 21 from causing system regulation failure, thereby improving system stability.

[0146] In one embodiment, the stabilizer bar power generation system 100 further includes:

[0147] A controller is connected to the opening regulating valve 21 and is used to regulate the opening regulating valve 21 .

[0148] In this embodiment, the system also includes a controller (not shown in the figure), which can be connected to the opening regulating valve 21 to adjust the opening regulating valve 21 to achieve coordinated adjustment of damping and power generation, so that the damping of the stabilizer bar 10 and the power generation of the stabilizer bar 10 can adapt to the operation of the vehicle under complex working conditions.

[0149] In one embodiment, the controller is further connected to the generator of the generator for regulating the generator.

[0150] In this embodiment, the controller is also connected to the generator of the generator for adjusting the generator so that the power generation performance of the generator can adapt to the changes in the fluid flow in the fluid pipeline 20, efficiently utilize the fluid energy in the fluid pipeline 20, and further improve the energy recovery rate.

[0151] This embodiment also provides a control method for a stabilizer bar power generation system, which can be applied to any controller provided in the embodiments of this application. Figure 2 The control method of the stabilizer bar power generation system provided in the embodiment of the present application includes:

[0152] Step S10 , adjusting the opening regulating valve in the stabilizer bar power generation system according to vehicle information.

[0153] In this embodiment, a stabilizer bar power generation system can be installed in a vehicle. The stabilizer bar in the stabilizer bar power generation system is connected to the vehicle's suspension. By adjusting the stabilizer bar's damping, the stabilizer bar can adapt to complex vehicle operating conditions, thereby better maintaining vehicle stability. Damping control for the stabilizer bar requires flow restriction, while power generation control for the stabilizer bar requires continuous fluid flow. Vehicle information can be obtained for the vehicle in which the stabilizer bar power generation system is installed. Vehicle information is relevant information during vehicle operation, such as vehicle speed, steering wheel angle, lateral acceleration, and road conditions. This information can characterize the vehicle's operating conditions, thereby determining whether the vehicle currently requires damping control or power generation control. The opening control valve in the stabilizer bar power generation system is adjusted based on this vehicle information. This allows for appropriate adjustment of the opening control valve, adaptively restricting fluid flow within the fluid conduit, and synergistically adjusting the stabilizer bar's damping and power generation. This results in improved power generation efficiency and stabilizer bar damping adjustment accuracy for the stabilizer bar power generation system, enabling the stabilizer bar power generation system to achieve excellent performance even under complex operating conditions.

[0154] In one embodiment, adjusting the opening regulating valve according to vehicle information includes:

[0155] determining a target opening of the opening regulating valve according to the vehicle information;

[0156] The opening regulating valve is adjusted according to the target opening.

[0157] In this embodiment, the required stabilizer bar performance can be determined based on vehicle information. When the vehicle information indicates instability, a lower target opening is selected, limiting the flow rate to increase stabilizer bar damping and prioritize vehicle stability. When the vehicle information indicates stability, a higher target opening is selected, increasing the flow rate to prioritize power generation based on the stabilizer bar. This method of determining the target opening of the regulating valve based on vehicle information allows for more precise coordinated control of damping and power generation.

[0158] In one embodiment, determining the target opening of the opening regulating valve according to the vehicle information includes:

[0159] determining control weight information between damping control and power generation control of the stabilizer bar power generation system based on the vehicle information;

[0160] The target opening of the opening regulating valve is determined according to the control weight information.

[0161] In this embodiment, vehicle information can characterize the operating condition of the vehicle, thereby determining the control weight information of the stabilizer bar power generation system on the vehicle that should perform damping control and power generation control on the stabilizer bar. The control weight information can characterize the current need to tend towards damping control to improve vehicle stability, or tend towards power generation control to improve power generation efficiency, thereby determining the appropriate target opening of the opening control valve based on the control weight information for opening adjustment.

[0162] In one embodiment, the control weight information includes a damping weight coefficient corresponding to the damping control, and determining the target opening of the opening regulating valve according to the control weight information includes:

[0163] The target opening of the opening regulating valve is determined according to the damping weight coefficient, the target damping torque of the damping control, and the hydraulic pressure difference between the two sides of the piston.

[0164] In this embodiment, the control weight information includes a damping weight coefficient corresponding to the damping control. The damping weight coefficient represents the degree of tendency toward damping control. The larger the damping weight coefficient, the greater the degree of damping control, and the larger the target opening should be. The target opening of the opening regulating valve is then determined based on the damping weight coefficient, the target damping torque of the damping control, and the hydraulic pressure difference on both sides of the piston. The target damping torque of the damping control can be the maximum damping torque that can be achieved when performing damping control, which is the torque with the strongest damping effect. The hydraulic pressure difference on both sides of the piston can be determined based on the hydraulic pressure collected by the first pressure sensor in the first cavity on both sides of the piston and the second pressure sensor in the second cavity. The specific formula for calculating the target opening can be as follows:

[0165]

[0166] in, is the target opening, is the valve flow coefficient, is the hydraulic pressure difference on both sides of the piston, is the target damping torque, is the damping weight coefficient.

[0167] Through the above formula, the maximum opening degree can be limited based on the damping weight coefficient to achieve the target damping torque, and the target opening degree can be calculated independently to improve the adjustment accuracy and efficiency.

[0168] In some embodiments, based on adjusting the opening control valve, the generator can also be synchronously adjusted to make it more adaptable to the flow rate changes caused by adjusting the opening control valve, thereby improving the power generation efficiency of the generator.

[0169] In one embodiment, the method further comprises:

[0170] determining a target load of a generator in the stabilizer bar power generation system according to the control weight information;

[0171] When the opening control valve is adjusted according to the target opening, the generator is simultaneously adjusted according to the target load.

[0172] In this embodiment, the opening regulating valve and the generator can be adjusted synchronously. The target opening of the opening regulating valve in the stabilizer bar power generation system can be determined according to the control weight information, and the target load of the generator in the stabilizer bar power generation system can also be determined. When the opening regulating valve is adjusted according to the target opening, the generator can be adjusted synchronously according to the target load. Since both are determined based on the control weight information, the coordination between the opening regulating valve and the generator can be improved, so that damping control and generator control can be reasonably performed, and it can be applicable to various complex working conditions of the vehicle.

[0173] In one embodiment, the control weight information includes a power generation weight coefficient corresponding to the power generation control, and determining the target load of the generator in the stabilizer bar power generation system according to the control weight information includes:

[0174] A target load of the generator is determined based on the power generation weight coefficient, the target power generation power of the power generation control, and the power generation voltage of the generator.

[0175] In this embodiment, the control weight information includes a power generation weight coefficient corresponding to the power generation control. The power generation weight coefficient represents the degree of tendency towards power generation control. The larger the power generation weight coefficient, the greater the degree of power generation control, and the smaller the target opening should be. At the same time, in order to adapt to the reduced flow rate, the load of the generator can also be increased to match the hydraulic energy that the system can provide, thereby improving power generation efficiency. The target load of the generator is then determined based on the power generation weight coefficient, the target power generation power of the power generation control, and the power generation voltage of the generator. The target power generation power of the power generation control can be the maximum power generation power that can be achieved when power generation control is performed, and the power generation voltage can be the rated voltage set for the generator. The formula for calculating the target load of the generator can be as follows:

[0176]

[0177] Among them, R load is the target load, P gen is the target power generation, V gen is the power generation voltage, and β is the power generation weight coefficient.

[0178] Through the above formula, the load corresponding to the target power generation can be restricted based on the power generation weight coefficient, the target load can be calculated independently, the adjustment accuracy and efficiency can be improved, and coordinated control based on the target load and target opening can be achieved. While achieving damping control, further power generation can be achieved, reducing energy loss.

[0179] In one example, a controller can output a PWM signal (e.g., frequency 1-10 kHz, duty cycle 20%-80%) to a control valve to adjust the flow rate of oil in a fluid pipeline. For example, a 50% duty cycle corresponds to a 50% opening of the control valve, allowing an oil flow rate of 25 L / min. The controller controls the generator's converter and adjusts the generator's load impedance based on the target load, e.g., 0.5-20 Ω, to match the current power demand.

[0180] This allows the control valve to receive currents corresponding to different duty cycles and achieve the corresponding target opening. Different openings correspond to different stabilizer bar damping, enabling adjustment of the stabilizer bar damping. The generator converter receives commands from the controller and adjusts the load to match the generated power.

[0181] In one embodiment, determining control weight information between damping control and power generation control of the stabilizer bar power generation system based on the vehicle information includes:

[0182] Fuzzy calculation is performed based on the vehicle information to determine control weight information between damping control and power generation control of the stabilizer bar power generation system.

[0183] In this embodiment, fuzzy calculation can be performed based on vehicle information to determine the control weight information between the damping control and power generation control of the stabilizer bar power generation system under the current vehicle information, thereby realizing dynamic decoupling and dynamically determining the control weight information according to the vehicle information, thereby improving the accuracy of the coordinated regulation of power generation and damping.

[0184] In one embodiment, performing fuzzy calculation based on the vehicle information to determine control weight information between damping control and power generation control of the stabilizer bar power generation system includes:

[0185] For at least one target vehicle information in the vehicle information, determining a matching degree between the target vehicle information and a plurality of fuzzy rules;

[0186] The control weight information is determined according to the matching degree corresponding to each of the fuzzy rules and the reference weight information corresponding to each of the fuzzy rules.

[0187] In this embodiment, during the fuzzy calculation process, at least one target vehicle information within the vehicle information can be used for fuzzy calculation. During the fuzzy calculation process, the degree of match between this target vehicle information and multiple fuzzy rules must be determined. Different fuzzy rules include reference weight information set based on different preset classification results of the vehicle information. Each fuzzy rule has corresponding preset reference weight information to indicate the degree to which the corresponding fuzzy rule favors power generation or damping control. By fusing the matching degrees corresponding to each fuzzy rule and the reference weight information corresponding to each fuzzy rule, more refined control weight information can be determined.

[0188] In one embodiment, the reference weight information includes a reference damping weight coefficient and / or a reference power generation weight coefficient.

[0189] In this embodiment, the reference weight information corresponding to each fuzzy rule may include a reference damping weight coefficient and / or a reference power generation weight coefficient. These two parameters are damping weight coefficients or power generation weight coefficients set in advance for the fuzzy rules to characterize the degree to which different fuzzy rules tend to power generation control or damping control.

[0190] In one embodiment, when the reference weight information includes a reference damping weight coefficient, determining the control weight information according to the matching degree corresponding to each fuzzy rule and the reference weight information corresponding to each fuzzy rule includes:

[0191] The center of gravity is calculated based on the matching degree corresponding to each fuzzy rule and the reference damping weight coefficient in the reference weight information corresponding to each fuzzy rule to obtain the damping weight coefficient, so as to obtain the control weight information.

[0192] In this embodiment, the reference weight information may include a reference damping weight coefficient, and the center of gravity calculation is performed based on the matching degree corresponding to each fuzzy rule and the reference damping weight coefficient in the reference weight information corresponding to each fuzzy rule. The center of gravity calculation is based on the matching degree corresponding to each fuzzy rule and the reference damping weight coefficient in the reference weight information corresponding to each fuzzy rule. After weighted summation, the result is compared with the sum of the reference damping weight coefficients in the reference weight information corresponding to each fuzzy rule, so as to realize the defuzzification of the fuzzy rules, thereby obtaining an accurate and appropriate damping weight coefficient to obtain the control weight information. The control weight information may also include a power generation weight coefficient. The power generation weight coefficient can be determined by subtracting the damping weight coefficient after the center of gravity calculation from a preset unit value (generally 1), and can also be used as control weight information to participate in collaborative control.

[0193] In one embodiment, when the reference weight information includes a reference power generation weight coefficient, determining the control weight information according to the matching degree corresponding to each fuzzy rule and the reference weight information corresponding to each fuzzy rule includes:

[0194] The center of gravity is calculated based on the matching degree corresponding to each fuzzy rule and the reference power generation weight coefficient in the reference weight information corresponding to each fuzzy rule to obtain the power generation weight coefficient and thus obtain the control weight information.

[0195] In this embodiment, the reference weight information may include a reference power generation weight coefficient, and the center of gravity calculation is performed based on the matching degree corresponding to each fuzzy rule and the reference power generation weight coefficient in the reference weight information corresponding to each fuzzy rule. The center of gravity calculation is based on the matching degree corresponding to each fuzzy rule and the reference power generation weight coefficient in the reference weight information corresponding to each fuzzy rule. After weighted summation, the result is compared with the sum of the reference power generation weight coefficients in the reference weight information corresponding to each fuzzy rule, so as to realize the defuzzification of the fuzzy rules, thereby obtaining an accurate and appropriate power generation weight coefficient to obtain the control weight information. The control weight information may also include a damping weight coefficient. The damping weight coefficient can be determined by subtracting the power generation weight coefficient after the center of gravity calculation from a preset unit value (generally 1), and can also be used as control weight information to participate in collaborative control.

[0196] In one embodiment, determining the matching degree between at least one target vehicle information in the vehicle information and a plurality of fuzzy rules includes:

[0197] For at least one type of target vehicle information in the vehicle information, determining a degree of membership of the target vehicle information under corresponding multiple preset classification results;

[0198] Based on the membership of the target vehicle information under the corresponding multiple preset classification results and the preset classification results configured in each of the fuzzy rules, the matching degree of the target vehicle information and each of the fuzzy rules is determined.

[0199] In this embodiment, at least one target vehicle information in the vehicle information is first fuzzified. Based on a predefined membership function, the membership of each target vehicle information under the corresponding multiple preset classification results can be determined. According to the membership of various target vehicle information under the corresponding multiple preset classification results, and the preset classification results configured for different vehicle information in each fuzzy rule are synthesized, so that the matching degree of these target vehicle information and each fuzzy rule can be determined.

[0200] In one example, the steps for determining the control weight information are as follows:

[0201] Step 1: Fuzzify the input parameters through the membership function, that is, fuzzify the target vehicle information;

[0202] The membership function is defined (using vehicle speed V as an example): Low speed (0-40 km / h): triangular function with a peak at 20 km / h; medium speed (30-70 km / h): trapezoidal function with a plateau between 40 and 60 km / h; high speed (60-120 km / h): Gaussian function with a mean of 90 km / h and a standard deviation of 15 km / h. The fuzzification process, when V = 35 km / h, yields membership of 0.8 for low speed, 0.2 for medium speed, and 0.0 for high speed.

[0203] Step 2: fuzzy rule reasoning;

[0204] Fuzzy rule base:

[0205]

[0206] Step 3: Rule triggering and weight synthesis;

[0207] When V = 35 km / h (low-speed membership is 0.8, medium-speed membership is 0.2) and the steering wheel angle θ = 8 (small-angle membership is 0.9, medium-angle membership is 0.1), fuzzy rules 1 and 3 are triggered. The matching calculation results of fuzzy rules 1 and 3 are: the proportion of rule 1 = 0.8 × 0.9 = 0.72; the proportion of rule 3 = 0.2 × 0.1 = 0.02.

[0208] Step 4: Defuzzify the output

[0209] Calculate the exact damping weight coefficient α and power generation weight coefficient β through the center of gravity:

[0210]

[0211] β=1-α=0.21

[0212] Among them, u i is the matching degree of the i-th rule, α i is the reference damping weight coefficient in the i-th rule.

[0213] Through the above fuzzy calculation, the accurate damping weight coefficient α and power generation weight coefficient β can be determined to determine the control weight information for coordinated control of the opening regulating valve and the generator.

[0214] In one embodiment, the method further comprises:

[0215] When the vehicle information satisfies the first preset condition of the balance control mode, control weight information between the damping control and the power generation control of the stabilizer bar power generation system is determined according to the vehicle information, and the target opening of the opening regulating valve is determined according to the control weight information.

[0216] In this embodiment, vehicle information may be information related to vehicle operation, including vehicle operating information and road condition information. The vehicle operating condition is evaluated based on the vehicle information, thereby switching the control mode of the stabilizer bar power generation system, such as a high damping control mode, a high power generation control mode, and a balanced control mode. The high damping control mode maintains a low fixed valve opening and a small generator load to ensure sufficient damping and low-power power generation. The high power generation control mode maintains a high fixed valve opening and a large generator load to provide less damping and ensure sufficient power generation. The balanced control mode allocates power generation weight coefficients and damping weight coefficients based on the operating conditions represented by the vehicle information. Fuzzy calculations can be used to allocate weights and calculate the target opening Kv, or the target opening Kv and the target generator load Rload, in real time. This allows for precise real-time adjustment of the opening control valve and generator in the system to achieve coordinated control.

[0217] In one example, if Figure 3 As shown in the figure, in the balancing mode, the vehicle information collected in real time is used as the variable input, and the membership degree of each type of vehicle information under the corresponding multiple preset categories is calculated to fuzzify the input variables. The matching degree is calculated through the defined fuzzy rule base, and then the fuzzification is performed through the center of gravity calculation to determine the target opening Kv and target load Rload, and the corresponding control signals are output to the opening control valve and generator for adjustment.

[0218] In one embodiment, the first preset condition includes: the vehicle information does not meet the second preset condition of the high power generation control mode, and the vehicle information does not meet the third preset condition of the high damping control mode.

[0219] In this embodiment, when the vehicle information neither meets the second preset condition of the high power generation control mode nor the third preset condition of the vehicle information high damping control mode, the stabilizer bar power generation system can perform a balanced control mode and determine the control weight information based on the real-time vehicle information to determine the target opening, or adjust the target opening and target load to achieve coordinated adjustment of power generation and damping.

[0220] In one embodiment, the vehicle information includes at least one of vehicle speed, steering wheel angle, and lateral acceleration. In some embodiments, the vehicle information may also include road condition information of the road on which the vehicle is traveling.

[0221] In one embodiment, the second preset condition includes: a steering wheel angle less than or equal to a preset angle, or the lateral acceleration less than a first lateral acceleration. When the steering wheel angle is less than or equal to the preset angle, or the lateral acceleration is less than the first lateral acceleration, it indicates that the vehicle is traveling in a straight line and is in a relatively stable state. In this case, damping requirements are low, and the stabilizer bar power generation system can operate in a high-power generation control mode, achieving high power generation and low damping operation, thereby improving the system's power generation efficiency under these conditions.

[0222] In one embodiment, the third preset condition includes: the vehicle speed being greater than a preset speed, or the lateral acceleration being greater than a second lateral acceleration. If the vehicle speed is greater than the preset speed, or the lateral acceleration is greater than the second lateral acceleration, it indicates that the vehicle is unstable. The stabilizer bar power generation system may then operate in a high-damping control mode, achieving low power generation and high-damping operation. This improves the stability of the system and the vehicle in which it is installed, thereby enhancing driving safety under these conditions.

[0223] In one embodiment, the method further comprises:

[0224] In a case where the vehicle information satisfies a second preset condition of the high power generation control mode, determining a first preset opening as the target opening; and / or,

[0225] When the vehicle information satisfies a third preset condition of the high damping control mode, a second preset opening degree is determined as the target opening degree, wherein the first preset opening degree is greater than the second preset opening degree.

[0226] In this embodiment, when the vehicle information meets the second preset condition of the high power generation control mode and the high power generation control mode is required, the first preset opening can be determined as the target opening. When the vehicle information meets the third preset condition of the high damping control mode and the high damping control mode is required, the second preset opening can be determined as the target opening. The first preset opening is greater than the second preset opening, so that the flow rate of the high damping control mode is less than the flow rate of the high power generation control mode, thereby achieving corresponding damping or power generation.

[0227] In one embodiment, in the high power generation control mode, the load of the generator is a first preset load, and in the high damping control mode, the load of the generator is a second preset load, and the first preset load is greater than the second preset load.

[0228] In this embodiment, in the high power generation control mode, the load adjusted for the load of the generator is the first preset load, and in the high damping control mode, the load adjusted for the load of the generator is the first preset load, thereby improving the power generation efficiency in the high power generation control mode and the high damping control mode.

[0229] In one embodiment, after adjusting the opening regulating valve in the stabilizer bar power generation system according to vehicle information, the method further includes:

[0230] The generator in the stabilizer bar power generation system is adjusted according to the flow rate of the fluid pipeline in the stabilizer bar power generation system and the hydraulic pressure difference between the two sides of the hydraulic motor of the stabilizer bar power generation system.

[0231] In some embodiments, when determining the target opening based on vehicle information, the target load of the generator can also be synchronously determined based on the control weight information determined based on the vehicle information, thereby achieving synchronous adjustment of the opening control valve and the generator, thereby improving response efficiency.

[0232] In this embodiment, a target opening can be determined based on vehicle information and adjusted accordingly. A first pressure sensor within the first chamber and a second pressure sensor within the second chamber measure the hydraulic pressure difference across the hydraulic motor of the stabilizer bar power generation system in real time. A flow sensor within the fluid pipeline measures the flow rate within the stabilizer bar power generation system. This data indicates the strength of the hydraulic energy, enabling precise, real-time adjustment of the generator to improve power generation efficiency.

[0233] In one embodiment, adjusting the generator in the stabilizer bar power generation system according to the flow rate of the fluid pipeline in the stabilizer bar power generation system and the hydraulic pressure difference between two sides of the hydraulic motor of the stabilizer bar power generation system includes:

[0234] determining available power generation according to the flow rate of the fluid pipeline and the hydraulic pressure difference between the two sides of the hydraulic motor;

[0235] The generator is regulated according to the available generated power.

[0236] In this embodiment, the available power generation provided by the hydraulic pressure can be calculated in real time based on the flow rate of the fluid pipeline and the hydraulic pressure difference on both sides of the hydraulic motor and the following formula:

[0237] Pgen'=η·Δp2·Q

[0238] Where Pgen' is the available power generation, η is the overall system efficiency, with a typical value of 0.75, Δp2 is the hydraulic pressure difference on both sides of the hydraulic motor, and Q is the flow rate of the fluid pipeline.

[0239] The generator is then adjusted according to the available power generation so that the generator can adapt to the fluid flow in the fluid pipeline and improve the power generation efficiency.

[0240] In one embodiment, adjusting the generator according to the available generated power includes:

[0241] determining a target load of the generator according to the available generated power and the generated voltage of the generator;

[0242] The generator is regulated according to the target load.

[0243] In this embodiment, the target load of the generator can be determined based on the available power and the generator voltage, as well as the following calculation formula, so that the generator can be accurately adjusted according to the target load:

[0244]

[0245] In one example, if Figure 4 As shown in the figure, the control process of the stabilizer bar power generation system includes three parts:

[0246] Perception part: includes the inertial measurement unit (IMU), the oil sensing system in the stabilizer bar power generation system, the power domain, etc.

[0247] The IMU collects the vehicle's linear and angular accelerations along the X, Y, and Z axes, and transmits the lateral acceleration to the controller via a serial peripheral interface (SPI). The oil sensing system uses turbine flowmeters and pressure sensors to obtain flow rate Q and hydraulic pressure P. In the power domain, the vehicle's current speed and gear position are transmitted to the controller via CAN communication. The controller reads the CAN signals to obtain vehicle information such as speed, gear position, and steering wheel angle.

[0248] Decision-making part: The controller mainly includes input signal processing module, working condition judgment module, dynamic decoupling module, and output signal processing module.

[0249] Among them, the input signal processing module converts the input signals of various communication modes to determine the vehicle information and outputs it to the working condition judgment module and the dynamic decoupling module.

[0250] The working condition judgment module can be divided into three modes based on vehicle information such as speed, steering angle, and lateral acceleration:

[0251] High power generation control mode (judgment conditions: steering wheel angle = 0° or lateral acceleration < 0.2g):

[0252] Control objective: Maximize power generation and increase the opening Kv of the control valve to 80%.

[0253] High damping control mode (judgment conditions: vehicle speed > 120km / h or lateral acceleration > 0.5g):

[0254] Control objective: Prioritize damping accuracy, and limit the opening Kv of the opening control valve to 20%.

[0255] Balanced Control Mode: (Judgment condition: High Power Generation Control Mode and High Power Generation Control Mode conditions are not met): The damping weight coefficients α and β for damping control are dynamically adjusted to ensure a balance between power generation and damping. The target opening and target load are determined based on α and β. Based on the target opening, the controller outputs a PWM signal (frequency 1-10kHz, duty cycle 20%-80%) to the opening control valve, driving it to output different currents to adjust the fluid flow. For example, a 50% duty cycle corresponds to a 50% opening of the solenoid valve, allowing an oil flow of 25 L / min. Based on the target load, the controller adjusts the generator's converter to adjust the load impedance, for example, from 0.5 to 20Ω, to match the current power demand.

[0256] In one example, the sensing component first transmits information such as a lateral acceleration of 0.1g, a vehicle speed of 60km / h, a steering wheel angle of 50°, and a pressure difference of 0.6MPa to the operating condition judgment module. The operating condition judgment module selects the high power generation mode based on the judgment condition that the acceleration is less than 0.2g. At this time, the target opening is fixed at 80%, corresponding to an 80% duty cycle. At this time, the allowed oil flow rate is 40L / min, and the generated power can be calculated as 320W. The target load of the generator is calculated according to the formula to obtain a load impedance of 7.2Ω. The PWM signal corresponding to the duty cycle and the load impedance signal are output to the corresponding opening control valve and generator, thereby controlling the proportional valve to open 80% and maintaining the generated power at 320W.
