Description

Technical Field

[0001] The present application relates to the field of stabilizer bar position detection, and in particular to an active stabilizer bar position detection mechanism and a detection method thereof. Background Art

[0002] At present, the automotive stabilizer bar system plays a vital role in modern vehicles, mainly used to adjust the vehicle roll angle and improve driving stability. The traditional passive stabilizer bar system relies on the stiffness and deformation characteristics of the physical structure to achieve this function, but its response speed is slow and difficult to control accurately. In recent years, with the development of electronic technology and mechatronics technology, active stabilizer bar systems have gradually become a research hotspot. This type of system can quickly adjust the position of the stabilizer bar in a short time by introducing electromagnetic coil drive, thereby more effectively improving the dynamic performance of the vehicle.

[0003] Existing active stabilizer bar systems usually use various sensors to detect the position of the stabilizer bar, including Hall sensors, photoelectric sensors, etc. These sensors can monitor the position changes of the stabilizer bar in real time and feed the data back to the control system. For example, the Hall sensor determines the position of the metal part by the change of the magnetic field, while the photoelectric sensor uses the blocking or reflection of the light beam to achieve position detection.

[0004] However, the sensors in the prior art are susceptible to magnetic field interference and mechanical vibration, resulting in reduced detection accuracy. Especially under complex road conditions, this interference is more obvious, which greatly reduces the robustness and reliability of the system. Therefore, how to achieve high-precision and high-reliability stabilizer bar position detection under complex working conditions is a technical problem that needs to be solved urgently. Summary of the invention

[0005] In order to improve the accuracy and reliability of stabilizer bar position detection, the present invention provides an active stabilizer bar position detection mechanism and a detection method thereof.

[0006] The present invention provides an active stabilizer bar position detection mechanism, which adopts the following technical solution: An active stabilizer bar position detection mechanism, comprising: A position loop, connected to the stabilizing rod, for generating a level signal; A level detection device, arranged near the position ring, for detecting a level signal of the current position of the position ring; A driving device, connected to the position ring, and used to drive the position ring to move; The controller is electrically connected to the driving device and the level detection device respectively, and is used to control the action of the driving device and receive the detection result of the level detection device.

[0007] By adopting the above technical solution, during the driving process of the vehicle, the controller controls the connection and disconnection of the stabilizer bar by controlling the driving voltage. At the same time, the driving device is responsible for driving the position ring to move and cooperate with the action instructions of the controller. Since different positions of the position ring generate different level signals, the system can accurately identify the position of the stabilizer bar, and the level signal of the current position of the position ring is detected in real time by the level detection device, thereby realizing accurate and real-time detection of the position state of the active stabilizer bar. The controller receives the detection results of the level detection device to realize closed-loop control and ensure the stability and reliability of the system. In general, this technical solution simplifies the complexity of traditional sensor detection methods, reduces system costs, improves the reliability and accuracy of position detection, and provides strong support for the stability and controllability of the vehicle during driving.

[0008] Preferably, the outer surface of the position ring is provided with a plurality of grooves and planes, wherein the level signal at the groove position is a low level 0, and the level signal at the plane position is a high level 1.

[0009] By adopting the above technical solution, the design of the groove and the plane makes the change of the level signal more obvious, thereby improving the detection accuracy. The setting of low level 0 and high level 1 simplifies the hardware requirements of the level detection device and reduces the complexity and cost of the system. In different positions, different combinations of level signals can clearly distinguish the specific state of the stabilizer bar and enhance the reliability of the system. This design not only improves the accuracy of position detection, but also can effectively identify the stuck state of the stabilizer bar under various working conditions, thereby improving the robustness of the system.

[0010] The present invention also provides an active stabilizer bar position detection mechanism, comprising the following steps: 1) Start the controller and apply a driving voltage to the stabilizing rod to change the position of the stabilizing rod, and at the same time, the driving device drives the position ring to move; the level detection device collects the level signal during the movement of the position ring; according to the change of the level signal collected by the level detection device, the position of the stabilizing rod is determined; 2) Turn off the controller and remove the driving voltage of the stabilizing rod, so that the position of the stabilizing rod changes, and at the same time, the driving device drives the position ring to move; the level detection device collects the level signal during the movement of the position ring; according to the change of the level signal collected by the level detection device, the position of the stabilizing rod is determined.

[0011] By adopting the above technical solution, accurate and real-time detection of the position of the active stabilizer bar is achieved. Specifically: 1. When the controller is started and the driving voltage is applied to the stabilizer bar, the level detection device can collect the level signal changes generated during the movement of the position ring in real time, so as to accurately judge the position state of the stabilizer bar, including the connection position, window position and disconnection position. 2. After the driving voltage is removed, the level detection device can also further confirm the position state of the stabilizer bar by collecting the changes in the level signal. This two-way detection mechanism not only improves the reliability of the detection, but also can timely feedback the actual position of the stabilizer bar under different working conditions, ensuring the stability and safety of the system.

[0012] Preferably, the level signal generated by the position loop is set to low level, high level, low level, high level in sequence, and the positions of the stabilizing rod corresponding to them are connection position, window position, transition position, and disconnection position in sequence.

[0013] By adopting the above technical solution, the accurate division of the position state of the active stabilizer bar is achieved. Specifically, by setting the specific level signal distribution on the position loop, the level state corresponding to different positions is clear and definite, so that when the controller detects the corresponding level change, the specific position of the stabilizer bar can be accurately determined. This method not only improves the reliability of position detection, but also simplifies the complexity of the system and reduces costs. At the same time, this level signal design method enhances the robustness of the system, reduces the possibility of misjudgment, and further improves the stability and safety of the vehicle during driving.

[0014] Preferably, the controller is started, and before the driving voltage is applied to the stabilizing bar for the first time, if the level collected by the level detection device is a low level, the stabilizing bar is in the connection position; If the level detected by the level detection device is a high level, the stabilizing rod is in the window position or the disconnected position.

[0015] By adopting the above technical solution, the initial position state of the stabilizer bar can be determined when the controller is powered on for the first time. Specifically: when the level detection device collects a low level, it means that the stabilizer bar has returned to the connected position, and the system can directly enter the normal working mode. When the level detection device collects a high level, it means that the stabilizer bar may be in the window position or the disconnected position. In these two cases, the specific position of the stabilizer bar needs to be further confirmed to ensure the safety and reliability of subsequent operations. This design effectively reduces the risk of misjudgment caused by uncertainty in the initial position and improves the robustness and safety of the system.

[0016] Preferably, if the initial position of the stabilizing bar is at the connection position, the controller is started and a driving voltage is applied to the stabilizing bar, then the position of the stabilizing bar includes: 1) If the level detection device collects zero upper edge interrupts and zero lower edge interrupts, the stabilizing bar is in a stuck state at the connection position; 2) If the level detection device collects one upper edge interruption and zero lower edge interruptions, the stabilizing bar is in a stuck state at the window position; 3) If the level detection device collects two upper edge interrupts and one lower edge interrupt, the stabilizing bar is in the disconnected position; Among them, the level state from high to low is a lower edge interrupt, and the level state from low to high is an upper edge interrupt.

[0017] By adopting the above technical solution, when the initial position of the stabilizer bar is at the connection position, the controller is started and the driving voltage is applied to the stabilizer bar, so that the specific position state of the stabilizer bar can be accurately determined. Specifically: 1. If the level detection device collects zero upper edge interruptions and zero lower edge interruptions, it means that the stabilizer bar is stuck in the connection position due to friction or other reasons and fails to be successfully pulled open. In this case, the system can timely identify the stuck state, avoid invalid continuous driving, reduce energy consumption and potential equipment damage risks. 2. If the level detection device collects one upper edge interruption and zero lower edge interruptions, it means that the stabilizer bar has moved from the connection position to the window position, but is stuck in this position due to some reasons (such as friction). This information helps the system to take further measures, such as increasing the driving voltage or extending the driving time, to ensure that the stabilizer bar reaches the target position smoothly. 3. If the level detection device collects two upper edge interruptions and one lower edge interruption, it means that the stabilizer bar has successfully moved from the connection position to the disconnection position. This state confirmation mechanism improves the reliability of the system and ensures that the vehicle can accurately adjust the position of the stabilizer bar when needed, thereby improving driving safety and comfort.

[0018] Preferably, if the initial position of the stabilizer bar is in the disconnected position, the controller is turned off, and the driving voltage of the stabilizer bar is removed, then the position of the stabilizer bar includes: 1) If the level detection device collects zero-order lower edge interruption and zero-order lower edge interruption, the stabilizing bar is in a stuck state in the disconnected position; 2) If the level detection device collects one lower edge interrupt and one upper edge interrupt, the stabilizing bar is in the window position; 3) If the level detection device collects two lower edge interrupts and one upper edge interrupt, the stabilizing bar is in the connected position; Among them, the level state from high to low is a lower edge interrupt, and the level state from low to high is an upper edge interrupt.

[0019] By adopting the above technical solution, the position state of the active stabilizer bar can be accurately and in real time detected. Specifically: 1. When the initial position of the stabilizer bar is in the disconnected position, after the controller is turned off and the driving voltage is removed, if the level detection device collects zero lower edge interrupts and zero upper edge interrupts, it means that the stabilizer bar is in a stuck state in the disconnected position. In this case, the system can promptly identify that the stabilizer bar cannot be reset normally, so as to take corresponding measures to avoid further damage. 2. If the level detection device collects one lower edge interrupt and one upper edge interrupt, it means that the stabilizer bar has moved from the disconnected position to the window position. In this process, the system accurately judges the position change of the stabilizer bar through the change of the level signal, ensuring the robustness and reliability of the system. 3. If the level detection device collects two lower edge interrupts and one upper edge interrupt, it means that the stabilizer bar has moved smoothly from the disconnected position to the connected position. This process also relies on the accurate detection of the level signal, ensuring that the stabilizer bar can quickly return to the connected state when needed, thereby improving the driving stability and safety of the vehicle.

[0020] In summary, this technical solution effectively solves the problems of low position detection accuracy and poor robustness in the prior art by accurately detecting the level signal, thereby improving the reliability and performance of the active stabilizer bar system.

[0021] Preferably, if the initial position of the stabilizer bar is at the window position, the controller is turned off, and the driving voltage of the stabilizer bar is removed, then the position of the stabilizer bar includes: 1) If the level detection device collects zero lower edge interrupts, the stabilizing bar is in a stuck state at the window position; 2) If the level detection device collects a lower edge interrupt, the stabilizing bar is in the connected position; If the initial position of the stabilizer bar is at the window position, the controller is started and a driving voltage is applied to the stabilizer bar, then the position of the stabilizer bar includes: 1) If the level detection device collects zero down edge interruption and zero down edge interruption, the stabilizing bar is in a stuck state at the window position; 2) If the level detection device collects one down-edge interrupt and one down-edge interrupt, the stabilizing bar is in the disconnected position; Among them, the level state from high to low is a lower edge interrupt, and the level state from low to high is an upper edge interrupt.

[0022] By adopting the above technical solution, when the stabilizing bar is in the window position, the specific position state of the stabilizing bar can be accurately determined by analyzing the number of lower edge interruptions collected by the level detection device. Specifically: 1. When the initial position is at the window position, the controller is turned off and the driving voltage is removed: if the lower edge interruption is not detected, it means that the stabilizing bar is stuck in the window position due to friction or other reasons and cannot return to the connection position normally; if a lower edge interruption is detected, it means that the stabilizing bar has successfully returned to the connection position. 2. When the initial position is at the window position, the controller is started and the driving voltage is applied to the stabilizing bar: if the lower edge interruption is not detected, it means that the stabilizing bar is stuck in the window position due to friction or other reasons and cannot be disconnected normally; if a lower edge interruption is detected, it means that the stabilizing bar has successfully reached the disconnection position.

[0023] Preferably, a time module is further included, and the time module includes a driving time and a waiting time, the driving time is used to apply a driving voltage to the stabilizing bar for T seconds, and the waiting time is used to remove the driving voltage of the stabilizing bar and then wait for t seconds.

[0024] By adopting the above technical solution, the introduction of the time module significantly improves the robustness and reliability of the active stabilizer bar position detection. The specific effects are as follows: By setting the drive time to T seconds, the problem of electromagnetic coil heating caused by long-term high-voltage drive is avoided, and the service life of the system is extended. The setting of the waiting time of t seconds allows the system to further confirm the position status of the stabilizer bar after the drive voltage is removed, reducing the possibility of misjudgment, especially in the stuck state, ensuring the accuracy of position detection.

[0025] Preferably, the steps of using the time module in the detection method of the active stabilizer bar position detection mechanism include: Step A: when the stabilizing bar is in the connection position or the window position, the controller is started to apply a driving voltage to the stabilizing bar for a second until the stabilizing bar reaches the disconnection position or reaches T seconds; If the stabilizer bar reaches the disconnected position, the controller switches to a voltage-maintaining mode; If the end position of the stabilizer bar is at the connection position or the window position after the driving voltage is applied to the stabilizer bar for T seconds, the controller is turned off, the driving voltage of the stabilizer bar is withdrawn, and the waiting time is entered. After the waiting time is over, it is determined whether the vehicle speed is greater than 0: ① If the vehicle speed is greater than zero, return to step A; ②If the vehicle speed is 0, wait until the vehicle speed is greater than 0 and enter step ①.

[0026] By adopting the above technical solution, the jamming problem caused by friction and abnormal angles can be effectively avoided during the driving process of the stabilizer bar, thereby improving the robustness and reliability of the system. Specifically: by setting the time module, the system can better judge the true position of the stabilizer bar and reduce misjudgment caused by environmental noise and mechanical vibration. In the process of applying the driving voltage, if the stabilizer bar fails to complete the action within the specified time, the system will stop the power supply in time, thereby avoiding the heating problem caused by long-term high-voltage driving. Only when the stabilizer bar is indeed in the disconnected position will the system switch to the voltage maintenance mode to ensure the safe driving of the vehicle. Through the continuously circulating time module mechanism, the system can restore the normal working state of the stabilizer bar in the shortest time, improving the response speed and efficiency of the entire system.

[0027] In summary, the present invention has the following beneficial effects: During vehicle driving, the controller controls the connection and disconnection of the stabilizer bar by controlling the driving voltage. At the same time, the driving device is responsible for driving the position ring to move and cooperate with the action instructions of the controller. Since different positions of the position ring generate different level signals, the system can accurately identify the position of the stabilizer bar. The level signal of the current position of the position ring is detected in real time by the level detection device, thereby realizing accurate and real-time detection of the position state of the active stabilizer bar. The controller receives the detection results of the level detection device to realize closed-loop control and ensure the stability and reliability of the system. In general, this technical solution simplifies the complexity of traditional sensor detection methods, reduces system costs, improves the reliability and accuracy of position detection, and provides strong support for the stability and controllability of the vehicle during driving.

[0036] Example 1 An active stabilizer bar position detection mechanism, referring to Figure 1 , including a position ring 2, a level detection device 3, a drive device 4 and a controller 5. The position ring 2 is connected to the stabilizing rod 1 and is used to generate a level signal. The level detection device 3 is arranged near the position ring 2 and is used to detect the level signal of the current position of the position ring 2. The drive device 4 is connected to the position ring 2 and is used to drive the position ring 2 to move. The drive device 4 and the level detection device 3 are both electrically connected to the controller 5, and the controller 5 is used to control the action of the drive device 4 and receive the detection result of the level detection device 3.

[0037] Reference Figure 2 The outer surface of the position ring 2 is provided with a plurality of grooves and planes, wherein the level signal at the groove position is a low level 0, and the level signal at the plane position is a high level 1.

[0038] Reference Figure 1 The driving device 4 is capable of driving the position ring 2 to move, which is a prior art and therefore will not be described in detail in this embodiment.

[0039] Reference Figure 1The stabilizing bar 1 is provided with a driving coil 6 and a spring 7. When the controller 5 applies a driving voltage to the driving coil 6, the stabilizing bar 1 can be disconnected. When the controller 5 removes the driving voltage, the spring 7 can drive the stabilizing bar 1 to reset, so that the stabilizing bar 1 is restored to the connected state.

[0040] The working principle of this embodiment is as follows: accurate and real-time detection of the position state of the active stabilizer bar 1 is achieved through a simplified level input method. The groove and plane design on the position ring 2 make the level signal change with the position of the stabilizer bar 1, and the level detection device 3 can efficiently capture these changes. The controller 5 can accurately determine the position of the stabilizer bar 1 by analyzing the changes in the level signal. This method not only reduces the complexity and cost of the system, but also improves the reliability and accuracy of position detection, providing strong support for improving the stability and controllability of the vehicle during driving.

[0041] Example 2 A detection method for an active stabilizer bar position detection mechanism, referring to Figure 3 , including the following steps: 1) Start the controller 5, apply a driving voltage to the stabilizing rod 1, so that the position of the stabilizing rod 1 changes, and at the same time, the driving device 4 drives the position ring 2 to move; the level detection device 3 collects the level signal during the movement of the position ring 2; according to the change of the level signal collected by the level detection device 3, the position of the stabilizing rod 1 is determined; 2) Turn off the controller 5 and remove the driving voltage of the stabilizing rod 1, so that the position of the stabilizing rod 1 changes, and at the same time, the driving device 4 drives the position ring 2 to move; the level detection device 3 collects the level signal during the movement of the position ring 2; according to the change of the level signal collected by the level detection device 3, the position of the stabilizing rod 1 is determined.

[0042] When the controller 5 is started and a driving voltage is applied to the stabilizer bar 1, the level detection device 3 can collect the level signal changes generated during the movement of the position ring 2 in real time, so as to accurately determine the position state of the stabilizer bar 1, including the connection position, window position and disconnection position. After the driving voltage is removed, the level detection device 3 can also further confirm the position state of the stabilizer bar 1 by collecting the changes in the level signal. This two-way detection mechanism not only improves the reliability of the detection, but also can timely feedback the actual position of the stabilizer bar 1 under different working conditions, ensuring the stability and safety of the system.

[0043] Reference Figure 2 and Figure 3 The level signal generated by the position ring 2 is set to low level, high level, low level, and high level in sequence, and the positions of the stabilizing rod 1 corresponding to the connection position, window position, transition position, and disconnection position in sequence.

[0044] The window position is a connection state of an optimal angle when the stabilizer bar 1 is connected. The transition position is used to separate the level states of the window position and the disconnection position.

[0045] By setting the specific level signal distribution on the position ring 2, the level states corresponding to different positions are clear and definite, so that when the controller 5 detects the corresponding level change, the specific position of the stabilizer bar 1 can be accurately determined. This method not only improves the reliability of position detection, but also simplifies the complexity of the system and reduces costs.

[0046] Reference Figure 2 and Figure 3 , the level state from high to low is a falling edge interrupt, and the level state from low to high is an rising edge interrupt.

[0047] Reference Figure 2 and Figure 3 , start the controller 5, before applying the driving voltage to the stabilizing bar 1 for the first time, if the level collected by the level detection device 3 is a low level, the stabilizing bar 1 is in the connection position; If the level collected by the level detection device 3 is a high level, the stabilizing rod 1 is in the window position or the disconnected position.

[0048] Reference Figure 2 and Figure 3 If the initial position of the stabilizer bar 1 is at the connection position, the controller 5 is started to apply a driving voltage to the stabilizer bar 1, and the position of the stabilizer bar 1 includes: 1) If the level detection device 3 collects zero upper edge interruptions and zero lower edge interruptions, the stabilizing rod 1 is in a stuck state at the connection position; 2) If the level detection device 3 collects one upper edge interruption and zero lower edge interruptions, the stabilizing rod 1 is in a stuck state at the window position; 3) If the level detection device 3 collects two upper edge interruptions and one lower edge interruption, the stabilizing rod 1 is in the disconnected position.

[0049] Reference Figure 2 and Figure 3 If the initial position of the stabilizer bar 1 is at the disconnected position, the controller 5 is turned off, and the driving voltage of the stabilizer bar 1 is removed, then the position of the stabilizer bar 1 includes: 1) If the level detection device 3 collects zero-order lower edge interruption and zero-order lower edge interruption, the stabilizing rod 1 is in a stuck state of the disconnected position; 2) If the level detection device 3 collects one lower edge interrupt and one upper edge interrupt, the stabilizing bar 1 is in the window position; 3) If the level detection device 3 detects two lower edge interruptions and one upper edge interruption, the stabilizing rod 1 is in the connection position.

[0050] Reference Figure 2 and Figure 3 If the initial position of the stabilizer bar 1 is at the window position, the controller 5 is turned off and the driving voltage of the stabilizer bar 1 is removed, then the position of the stabilizer bar 1 includes: 1) If the level detection device 3 collects zero lower edge interrupts, the stabilizing rod 1 is in a stuck state at the window position; 2) If the level detection device 3 detects a lower edge interrupt, the stabilizing bar 1 is in the connection position.

[0051] Reference Figure 2 and Figure 3 If the initial position of the stabilizer bar 1 is at the window position, the controller 5 is started to apply a driving voltage to the stabilizer bar 1, and the position of the stabilizer bar 1 includes: 1) If the level detection device 3 collects zero-order lower edge interruption and zero-order lower edge interruption, the stabilizing rod 1 is in a stuck state at the window position; 2) If the level detection device 3 collects one down edge interrupt and one down edge interrupt, the stabilizing bar 1 is in the disconnected position.

[0052] Reference Figure 4 The detection method of the active stabilizer bar position detection mechanism is further provided with a time module, which includes a driving time and a waiting time. The driving time is used to apply a driving voltage to the stabilizer bar 1 for T seconds. The waiting time is used to remove the driving voltage of the stabilizer bar 1 and then wait for t seconds.

[0053] Reference Figure 4 The steps of using the time module in the detection method of the active stabilizer bar position detection mechanism include: Step A: When the stabilizing bar 1 is in the connection position or the window position, the controller 5 is started to apply a driving voltage to the stabilizing bar 1 for a second until the stabilizing bar 1 reaches the disconnection position or reaches T seconds; If the stabilizer bar 1 reaches the disconnected position, the controller 5 switches to the voltage holding mode; If the end position of the stabilizer bar 1 is at the connection position or the window position after the driving voltage is applied to the stabilizer bar 1 for T seconds, the controller 5 is turned off, the driving voltage of the stabilizer bar 1 is withdrawn, and the waiting time begins. After the waiting time ends, it is determined whether the vehicle speed is greater than 0: ① If the vehicle speed is greater than zero, return to step A; ②If the vehicle speed is 0, wait until the vehicle speed is greater than 0 and enter step ①.

[0054] The operating principle of the present application is as follows: based on the information of the initial position, combined with the level detection device 3 received by the controller 5, the level signal changes generated during the movement of the position ring 2 are collected in real time, so as to accurately judge the position state of the stabilizing rod 1, including the connection position, window position and disconnection position.

[0055] By introducing the time module, the problem of the stabilizer bar 1 being stuck due to friction or other factors is effectively solved. The design of the time module can not only confirm the authenticity of the position change, but also prevent overheating under high-voltage driving. This design improves the robustness and reliability of the entire system and ensures the safety and stability of vehicle driving.
