Description

Technical Field

[0001] The invention relates to the field of damping control technology, and in particular to a damping control system combining sensing technology with intelligent algorithms. Background Art

[0002] Its damping control is mainly achieved by suppressing the vibration of the vehicle during driving; for example, in the vehicle suspension system, the damping force is like a "regulator". When the wheels encounter bumps or potholes on the road, or when the vehicle accelerates, brakes, turns, etc., different degrees of vibration and impact will be generated, and the damping device will intervene; it uses the internal mechanical structure, hydraulic or pneumatic system, and electromagnetic effect to generate resistance in the opposite direction of the vibration, that is, the damping force, to reduce the vibration amplitude and prevent excessive shaking and bumps.

[0003] The application with publication number CN105082920B discloses a coordinated control system and method for an interconnected air suspension with adjustable damping and vehicle height, including a sensor module, a road roughness identification module, a driver command acquisition module, a coordination controller, an interconnected state controller, an interconnected state control actuator, a damping controller, a damping control actuator, a vehicle height controller and a vehicle height control actuator. First, interconnected state control, vehicle height control and damping control strategies are formulated; then a coordination controller is established to allocate the working order of each controller according to the current driving condition, and specific control statements are corrected. The vehicle height control is corrected according to the interconnected state and the damping coefficient, and the interconnected state control and the damping control are corrected according to the correction coefficient provided by the coordination controller; the present invention can effectively coordinate the operation of the interconnected state control system, the vehicle height control system and the damping control system, and significantly improve the comprehensive performance of the interconnected air suspension with adjustable damping and vehicle height.

[0004] During the damping control process of the vehicle body, precise damping control is generally performed based on the amplitude changes of the vehicle body itself, so that the vehicle body can be effectively cushioned. However, in the actual control process, the impact of the oil movement or aging of the damper is not numerically confirmed, resulting in a specific difference between the controlled damping force and the damping force actually required by the vehicle body. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a damping control system that combines sensing technology and intelligent algorithms, which solves the problem of failure to numerically confirm the impact of the oil movement or aging of the damper.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a damping control system combining sensing technology and intelligent algorithm, comprising:

[0007] The instantaneous speed monitoring end monitors the instantaneous spring-up speed and the instantaneous displacement vector of the wheel, and transmits the monitored instantaneous spring-up speed to the instantaneous elastic force confirmation end;

[0008] The instantaneous elastic force confirmation end confirms the instantaneous elastic force generated by the current wheel based on the monitored instantaneous spring-up speed and instantaneous displacement vector, and transmits the confirmed instantaneous elastic force to the damping force locking end, specifically in the following manner:

[0009] Based on the monitored instantaneous bounce speed, the instantaneous acceleration in the corresponding unit is confirmed. There are two groups of instantaneous bounce speeds. The confirmed instantaneous acceleration is calibrated as A, where A = |difference between the two groups of instantaneous bounce speeds| ÷ time difference between the two groups of instantaneous bounce speeds. Based on the instantaneous acceleration A and the vehicle mass m, where m is a preset value, the characteristic force is confirmed, and the characteristic force = m×A;

[0010] Based on the confirmed instantaneous displacement vector, the angle JJ between the instantaneous displacement vector and the vertical direction is confirmed, and the instantaneous elastic force generated by the wheel at the current moment is confirmed using: instantaneous elastic force = characteristic force × CosJJ;

[0011] The damping force locking end allocates the damping force and the spring force based on the instantaneous elastic force confirmed at the current moment, and then confirms the reverse force based on the allocated spring force, identifies the standard ratio between the reverse force and the damping force, and confirms the standard ratios associated with different combinations through multiple combinations, selects the combination associated with the best standard ratio, and confirms the damping force. The specific method is as follows:

[0012] The instantaneous elastic force confirmed at the current moment is calibrated as TL, and the damping force and the spring elastic force are randomly distributed to TL, the sum of the distributed damping force and the spring force is TL, and the distributed different damping forces and spring forces are used as different distribution combinations;

[0013] Confirm the standard ratio for different distribution combinations: calibrate the damping force associated with this distribution combination as ZN i , and the associated spring force is calibrated as DL i , where i represents different allocation combinations, using FX i =DL i ×C1 confirms the reverse force associated with this spring force, where C1 is the preset fixed coefficient factor, using: B i =FX i ÷ZN i Confirm the standard ratio B associated with the corresponding opposing force in the corresponding distribution combination i ;

[0014] Different standard ratios B associated with different allocation combinations iVerify with the set standard Y1, where Y1 is the preset value, using PD i =|B i -Y1|Determine the evaluation value, from the different evaluation values ​​PD associated with different allocation combinations i In the PD i The distribution combination associated with min is used as the execution combination, and the damping force confirmed in the execution combination is transmitted to the control center;

[0015] The control center regulates the hydraulic damping of the hydraulic system in the suspension according to the confirmed damping force, so that the hydraulic damping is adjusted to the same value as the damping force;

[0016] After the control center completes the corresponding damping force control process, it generates a control signal and transmits it to the error confirmation end, which confirms the vibration height of the vehicle body, confirms the first set of vibration amplitudes generated by the vehicle body based on the displacement sensor set in the vehicle body, and then identifies whether the vibration amplitude of the vehicle body meets the standard;

[0017] The damping calibration center, based on the received error signal, rechecks the determined vibration amplitude and the preset error standard interval to determine the high and low trends of the vibration amplitude, and then locks the calibration trend of the damping force based on the determined high and low trends, and performs preliminary calibration. Then, based on the amplitude change associated with the preliminary calibration, the calibration value of this stage is confirmed, and the confirmed calibration value is transmitted to the control center. The specific method is as follows:

[0018] Based on the received error signal, confirm the vibration amplitude ZD and the error interval associated with the error signal. If ZD>error interval, it means that the vibration amplitude is in a high trend. If ZD<error interval, it means that the vibration amplitude is in a low trend.

[0019] If the vibration amplitude is in a high trend, a damping high calibration is performed, the confirmed preliminary calibration value is "+1", and the error value is determined, the error value = ZD-the maximum value of the error standard interval, and the confirmed preliminary calibration value is transmitted to the control center; if the vibration amplitude is in a low trend, a damping low calibration is performed, the confirmed preliminary calibration value is "-1", and the error value is determined, the error value = the minimum value of the error standard interval-ZD, and the confirmed preliminary calibration value is transmitted to the control center;

[0020] After completing the preliminary calibration, the damping calibration center reconfirms the calibrated oscillation amplitude, and uses the same method as above to confirm the vibration amplitude and the error value between the error standards, calibrates the error value determined this time as the secondary value, and calibrates the error value associated with the previous error signal as the primary value, and uses: primary value - secondary value = change value to determine the change value associated with the preliminary damping calibration;

[0021] Then use: secondary value ÷ change value = G, if G is not a positive integer, round it up, if G is a positive integer, do nothing;

[0022] Confirm the calibration value G associated with this error signal, transmit the confirmed calibration value G to the control center, and then the control center adjusts the damping force ZN based on the determined calibration value G. i If the vibration amplitude is high during the initial calibration, adjust the controlled damping force to (ZN i +G), if the vibration amplitude is low during the initial calibration, the controlled damping force is adjusted to (ZN i -G).

[0023] Preferably, the instantaneous spring-up speed is monitored and collected by an instantaneous sensor, and its instantaneous displacement vector is monitored and collected by a displacement sensor arranged in the wheel.

[0024] Preferably, the specific method of the error confirmation end for identifying whether the vibration amplitude of the vehicle body meets the standard is:

[0025] The first group of vibration amplitudes of the vehicle body monitored by the displacement sensor is calibrated as ZD, and the monitored vibration amplitude ZD is compared with the set error standard interval, and the error standard interval is a preset value interval. If If ZD∈error standard interval, an error signal is generated and transmitted to the damping calibration center; if ZD∈error standard interval, no processing is performed, and the body vibration amplitude associated with the subsequent control signal is monitored and analyzed.

[0026] The present invention provides a damping control system that combines sensing technology and intelligent algorithms. Compared with the prior art, it has the following beneficial effects:

[0027] The instantaneous bounce speed and displacement vector of the wheel are accurately collected by using the instantaneous sensor and displacement sensor, and the instantaneous elastic force is accurately calculated by comprehensively considering multiple factors. Compared with the traditional method of estimating only a single characteristic force, the accuracy of instantaneous elastic force confirmation is greatly improved, laying a solid foundation for subsequent precise damping control.

[0028] By confirming multiple combinations in sequence, comparing the standard ratios of the reverse force and the damping force under different combinations, the damping force corresponding to the best combination is selected to ensure that the buffering and shock absorption performance of the suspension system can be optimized under various driving conditions, effectively improving driving comfort and reducing vehicle bumps.

[0029] The damping calibration center intelligently calibrates the damping force according to the high and low trends of the vibration amplitude. The calibration process is not a simple one-time adjustment, but a gradual optimization of the damping force through rigorous error value calculation and change value analysis, ensuring that the damper always maintains good performance under long-term use or complex working conditions, further improving the stability and reliability of the driving experience.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] First embodiment

[0034] See also Figure 1 , the present application provides a damping control system combining sensing technology and intelligent algorithm, including an instantaneous speed monitoring terminal, an instantaneous elastic force confirmation terminal, a damping force locking terminal, a control center, an error confirmation terminal and a damping calibration center, wherein the instantaneous speed monitoring terminal is electrically connected to an input node of the instantaneous elastic force confirmation terminal, and the instantaneous elastic force confirmation terminal is electrically connected to an input node of the damping force locking terminal, and the damping force locking terminal is electrically connected to an input node of the control center, and the control center, the error confirmation terminal and the damping calibration center are electrically connected from the output node to the input node in sequence;

[0035] The instantaneous speed monitoring end monitors the instantaneous bounce speed and instantaneous displacement vector of the wheel, and transmits the monitored instantaneous bounce speed to the instantaneous elastic force confirmation end. The instantaneous bounce speed is monitored and collected by the instantaneous sensor, and the instantaneous displacement vector is monitored and collected by the displacement sensor arranged in the wheel. Specifically, according to the monitored instantaneous bounce speed, the corresponding instantaneous acceleration can be locked, and based on the corresponding displacement vector, the direction of the corresponding resistance is confirmed to lock the corresponding instantaneous elastic force.

[0036] The instantaneous elastic force confirmation end confirms the instantaneous elastic force generated by the current wheel based on the monitored instantaneous spring-up speed and instantaneous displacement vector, and transmits the confirmed instantaneous elastic force to the damping force locking end, wherein the specific method of confirming the instantaneous elastic force is:

[0037] Based on the monitored instantaneous bounce speed, the instantaneous acceleration in the corresponding unit is confirmed. There are two groups of instantaneous bounce speeds. The confirmed instantaneous acceleration is calibrated as A, where A = |difference between the two groups of instantaneous bounce speeds| ÷ time difference between the two groups of instantaneous bounce speeds. Based on this instantaneous acceleration A and the vehicle mass m, where m is a preset value, which is prepared in advance by relevant operators based on experience, the characteristic force is confirmed, and the characteristic force = m×A;

[0038] Combination Figure 2 , based on the confirmed instantaneous displacement vector, confirm the angle JJ between the instantaneous displacement vector and the vertical direction, and use: instantaneous elastic force = characteristic force × CosJJ (based on trigonometric functions, confirm the elastic force in the vertical direction) to confirm the instantaneous elastic force generated by the wheel at the current moment;

[0039] Specifically, this method of adding displacement confirmation can make the confirmed instantaneous elastic force more accurate. In the prior art, the confirmed characteristic force is generally used as the instantaneous elastic force, but this confirmation method will have a certain force deviation. By adopting this method, the determined force value can be effectively made more accurate, and the accuracy is higher.

[0040] Among them, the damping force locking end allocates the damping force and the spring force based on the instantaneous elastic force confirmed at the current moment, and then confirms the reverse force based on the allocated spring force, identifies the standard ratio between the reverse force and the damping force, confirms the standard ratios associated with different combinations through multiple combinations, selects the combination associated with the best standard ratio, confirms the damping force, and transmits the confirmed damping force to the control center;

[0041] The instantaneous elastic force confirmed at the current moment is calibrated as TL, and the damping force and spring elastic force are randomly distributed to TL. The sum of the distributed damping force and elastic force is TL, and the distributed different damping forces and elastic forces are used as different distribution combinations (the damping force is used to buffer the force first, and the remaining force after buffering is buffered by the spring elastic force, so the elastic force value of the corresponding spring can be confirmed);

[0042] Confirm the standard ratio for different distribution combinations: calibrate the damping force associated with this distribution combination as ZN i , and the associated spring force is calibrated as DL i , where i represents different allocation combinations, using FX i =DL i ×C1 confirms the reverse force associated with this spring force (the so-called reverse force is that the damping spring will rebound after being compressed, and this reverse force is the elastic force generated during the rebound). C1 is a preset fixed coefficient factor, and its specific value is determined by the operator based on experience, using: B i =FX i ÷ZN iConfirm the standard ratio B associated with the corresponding opposing force in the corresponding distribution combination i ;

[0043] Different standard ratios B associated with different allocation combinations i Verify with the set standard Y1, where Y1 is the preset value, and its specific value is determined by the relevant operators based on experience, using PD i =|B i -Y1|Determine the evaluation value, from the different evaluation values ​​PD associated with different allocation combinations i In the PD i min is used as the execution combination, and the damping force confirmed in the execution combination is transmitted to the control center.

[0044] Its control center regulates the hydraulic damping of the hydraulic system in the suspension according to the confirmed damping force, so that the hydraulic damping is adjusted to the same value as the damping force.

[0045] Specifically, this is the preliminary control process of damping. Based on the determined instantaneous elastic force, the damping force and the spring force are specifically distributed. From the specific distribution process, the different reverse forces associated with different spring forces are confirmed. Based on the correlation ratio between the corresponding reverse force and the corresponding damping force, the optimal damping force is selected. Based on the selected optimal damping force, the hydraulic damping is adjusted to enable the current vehicle to achieve better buffering and shock absorption effects and enhance the driving experience of its drivers and passengers.

[0046] Second embodiment

[0047] In the specific implementation process of this embodiment, compared with the above embodiment, this embodiment mainly focuses on the secondary control process of the damping force, and the corresponding error confirmation end and the damping calibration center perform calibration confirmation;

[0048] After the control center completes the corresponding damping force control process, it generates a control signal and transmits it to the error confirmation end. The error confirmation end confirms the vibration height of the vehicle body, and based on the displacement sensor set in the vehicle body, confirms the first set of vibration amplitudes (that is, displacement) generated by the vehicle body, and then identifies whether the vibration amplitude of the vehicle body meets the standard. The specific method of identification is:

[0049] The first group of vibration amplitudes of the vehicle body monitored by the displacement sensor is calibrated as ZD, and the monitored vibration amplitude ZD is checked with the set error standard interval. The error standard interval is a preset numerical interval, which is formulated by relevant operators based on experience. If ZD∈error standard interval, no processing is performed, and the vehicle body vibration amplitude associated with the subsequent control signal is monitored and analyzed. If If the error is within the standard range, an error signal is generated, and the generated error signal is transmitted to the damping calibration center;

[0050] When the vibration amplitude of the vehicle body belongs to the corresponding error standard range, it means that after setting the corresponding damping force, when the vibration amplitude of the vehicle body itself is in a normal state, the vibration amplitude generated will belong to the corresponding error standard range. If the vibration amplitude of the vehicle body itself is not in a normal state, the vibration amplitude generated will not belong to the corresponding error standard range. After the damping force is set, but the error is still too large, it means that the corresponding damper is aging, resulting in the inability to meet the corresponding damping requirements after the damping force is set. Therefore, it is necessary to use the corresponding damping calibration center to perform damping calibration to further improve the damping effect of the damper;

[0051] The damping calibration center, based on the received error signal, rechecks the determined vibration amplitude and the preset error standard interval to determine the high and low trends of the vibration amplitude, and then locks the calibration trend of the damping force based on the determined high and low trends, and performs preliminary calibration, and then confirms the calibration value of this stage according to the amplitude change associated with the preliminary calibration, and transmits the confirmed calibration value to the control center, wherein the specific method of determining the calibration value is:

[0052] Based on the received error signal, confirm the vibration amplitude ZD and the error interval associated with the error signal. If ZD>error interval, it means that the vibration amplitude is in a high trend. If ZD<error interval, it means that the vibration amplitude is in a low trend.

[0053] If the vibration amplitude is in a high trend, a damping high calibration is performed, the confirmed preliminary calibration value is "+1", and the error value is determined, and the error value = ZD-the maximum value of the error standard interval, and the confirmed preliminary calibration value is transmitted to the control center. If the vibration amplitude is in a low trend, a damping low calibration is performed, the confirmed preliminary calibration value is "-1", and the error value is determined, and the error value = the minimum value of the error standard interval-ZD, and the confirmed preliminary calibration value is transmitted to the control center. Specifically, if the damping force received by the control center in the next stage is 50, then after calibration, the control center will be directly adjusted to 51 or 49;

[0054] After completing the preliminary calibration, the damping calibration center reconfirms the calibrated oscillation amplitude, and uses the same method as above to confirm the vibration amplitude and the error value between the error standards, calibrates the error value determined this time as the secondary value, and calibrates the error value associated with the previous error signal as the primary value, and uses: primary value - secondary value = change value to determine the change value associated with the preliminary damping calibration;

[0055] Then use: secondary value ÷ change value = G, if G is not a positive integer, round it up, if G is a positive integer, do nothing;

[0056] Confirm the calibration value G associated with this error signal, transmit the confirmed calibration value G to the control center, and then the control center adjusts the damping force ZN based on the determined calibration value G. i If the vibration amplitude is high during the initial calibration, adjust the controlled damping force to (ZN i +G), if the vibration amplitude is low during the initial calibration, the controlled damping force is adjusted to (ZN i -G);

[0057] Each different processing stage requires the execution of a corresponding calibration process. That is, after the error signal is generated, the subsequent error signal will be generated and calibrated again only after the damping force calibration process of this processing stage is completed. Under normal circumstances, multiple calibrations are not required and generally will not occur in a short period of time. Therefore, the time span of the calibration process in each stage will be very large.

[0058] Specifically, after calibrating the damping force, the corresponding control process can be effectively controlled more accurately, thereby improving the overall effect of the damping control.

[0059] Some of the data in the above formulas are numerically calculated by removing their dimensions. Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0060] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
