[0057] The road feeling simulation device 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0058] Reference Figure 1-Figure 8As shown, the road feeling simulation device 100 according to the embodiment of the present invention may include: a first road feeling simulation module and a steering wheel 30 .

[0059] Specifically, the first road feel simulation module is connected to the steering wheel 30 , and the first road feel simulation module is suitable for providing a circumferential rotation damping force for the steering wheel 30 , so that the driver can experience a more realistic driving feeling during the steering process, thereby improving the driving experience.

[0060] The inventors of the present application discovered that in the related art, during the steering process of a vehicle, the road feel feedback only simulates the damping of the steering wheel rotation during the steering process of the vehicle. The simulation result is relatively smooth and cannot provide the driver with the required road feel information. In addition, the road feel feedback with only the steering damping feeling is not easy to judge the vehicle status and corresponding operations during the driving process, which can easily affect the driving safety of the vehicle.

[0061] Therefore, in the present invention, if Figure 2-Figure 5 As shown, the road feeling simulation device 100 further includes a second road feeling simulation module 10, which is connected to the steering wheel 30, and is suitable for providing vibration damping force for the steering wheel 30. Therefore, during the driving process of the vehicle, the vibration generated by the road surface excitation can be simulated by the second road feeling simulation module 10 and transmitted to the steering wheel 30, so that multi-angle road feeling simulation can be realized during the driving process of the vehicle, and more realistic road feeling feedback of the steering wheel 30 during the driving process can be realized, so as to meet the driving needs of different drivers, facilitate the driver to judge the vehicle state, determine the cornering angle and vehicle speed, judge the grip of the wheel, etc., meet the required driving feedback needs, and ensure the driving safety and comfort of the vehicle.

[0062] The road feel simulation device 100 according to the embodiment of the present invention is connected to the steering wheel 30 via the first road feel simulation module, and is suitable for providing circumferential rotation damping force for the steering wheel 30. The second road feel simulation module 10 is connected to the steering wheel 30, and is suitable for providing vibration damping force for the steering wheel 30. It can realize multi-angle road feel simulation during vehicle driving, realize more realistic road feel feedback of the steering wheel 30 during driving, meet the driving needs of different drivers, facilitate the driver to judge the vehicle status, meet the required driving feedback needs, and ensure the driving safety and comfort of the vehicle.

[0063] In some embodiments of the present invention, the second road feel simulation module 10 provides axial vibration damping force and / or circumferential vibration damping force for the steering wheel 30, that is, the second road feel simulation module 10 can provide axial vibration damping force for the steering wheel 30, or the second road feel simulation module 10 can provide circumferential vibration damping force for the steering wheel 30, or the second road feel simulation module 10 can provide axial vibration damping force and circumferential vibration damping force for the steering wheel 30, to meet the required road excitation feedback requirements, achieve more realistic road feel feedback of the steering wheel 30 during driving, meet the different needs of different drivers during driving, facilitate the driver to judge the vehicle status, and ensure the driving safety and comfort of the vehicle.

[0064] According to some embodiments of the present invention, Figure 4-Figure 8 As shown, the second road feel simulation module 10 includes a vibration generating component 11, which includes a shell 111 and a baffle component 112. The shell 111 has a accommodating cavity 113, and the baffle component 112 is arranged in the accommodating cavity 113. The accommodating cavity 113 can accommodate liquid. The baffle component 112 includes a baffle body 20, which is connected to the shell 111, and can realize the connection between the baffle component 112 and the shell 111, ensuring that the baffle component 112 is fixed in the shell 111.

[0065] The steering wheel 30 is located at one end of the housing 111 in the length direction (eg Figure 4 The steering wheel 30 is connected to at least one of the baffle assembly 112 and the shell 111, that is, the steering wheel 30 can be connected to the baffle assembly 112, or the steering wheel 30 can be connected to the baffle assembly 112, or the steering wheel 30 can be connected to the baffle assembly 112 and the shell 111, all of which can meet the connection requirements of the steering wheel 30 and the vibration generating assembly 11.

[0066] At the same time, if Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the second road sense simulation module 10 further includes a driving assembly 12, and the baffle assembly 112 further includes a first baffle 21, which is disposed on the baffle body 20, and the first baffle 21 is connected to the housing 111 in the length direction (for example Figure 4), the driving component 12 can drive the liquid in the accommodating chamber 113 to flow, and the liquid flows in the accommodating chamber 113, for example, the driving component 12 controls the directional and constant speed flow of the liquid, so that the liquid can hit the first baffle 21, and the axial vibration generated by the liquid hitting the first baffle 21 can be transmitted to the steering wheel 30, so that the second road sense simulation module 10 provides the steering wheel 30 with an axial vibration damping force, realizes the required road excitation feedback, and realizes a more realistic road sense feedback of the steering wheel 30 during driving. By controlling the driving component 12, the road sense simulation device 100 can generate a vibration movement with controllable direction, controllable force, and controllable frequency, so as to meet the different needs of different drivers during driving. For example, when the vehicle is driving in a straight line, the road excitation required for road sense can be provided through axial vibration.

[0067] In addition, compared with the related art that realizes road feel feedback through mechanical structure, the second road feel simulation module 10 of the present invention has the advantages of simple control and rapid response, and can simulate small vibrations to make the vibration feel more realistic, ensuring the authenticity of the feedback, thereby ensuring the driving safety of the vehicle.

[0068] It should be noted that, for the convenience of description, the directions such as “upper” and “lower” in the present invention are based on the directions shown in the accompanying drawings, and are not limitations on the directions in actual application.

[0069] In some embodiments of the present invention, Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the baffle assembly 112 also includes a second baffle 22, which is arranged on the baffle body 20 and extends along the length direction of the shell 111, and the second baffle 22 is parallel to the length direction of the shell 111. The driving assembly 12 can also drive the liquid in the accommodating chamber 113 to flow. The liquid flows in the accommodating chamber 113, for example, the driving assembly 12 controls the directional and constant speed flow of the liquid, so that the liquid can hit the second baffle 22, and the tangential vibration generated by the liquid hitting the second baffle 22 can be transmitted to the steering wheel 30, so that the second road sense simulation module 10 provides a circumferential vibration damping force for the steering wheel 30, and realizes the road excitation feedback required by the vehicle during the steering process, and realizes a more realistic road sense feedback of the steering wheel 30 during driving. By controlling the driving assembly 12, the road sense simulation device 100 can generate a vibration movement with controllable direction, controllable force and controllable frequency, which meets the different needs of different drivers during driving, and can simulate small vibrations, so that the vibration sense is more realistic, and the feedback is realistic, thereby ensuring the driving safety of the vehicle.

[0070] In some embodiments, when the control drive assembly 12 drives the liquid in the accommodating chamber 113 to flow so as to hit the second baffle 22, the circumferential rotation of the liquid in the accommodating chamber 113 can be in the same direction as the basic damping force, and the speed of the liquid rotation can correspond to different vibration amplitudes, thereby effectively characterizing the characteristic road feel during the steering process and making the feedback more realistic.

[0071] In some embodiments, the vehicle's steer-by-wire system can realize intelligent driving of the vehicle, realize a modular structure, have the characteristics of adjustable system parameters, and improve the flexibility of vehicle dynamics system design. Since the steer-by-wire system removes the mechanical connection between the steering wheel 30 and the steering execution module, the road feeling information generated by the contact between the vehicle's wheels and the road surface cannot be directly fed back to the driver, affecting the driver's driving feeling and thus affecting the safety of vehicle driving.

[0072] In the related technology, by increasing the damping feeling when the steering wheel is turned, the driver can experience a more realistic driving feeling during the steering process. However, the road feel feedback of the steering damping feeling is not easy to judge the vehicle state and corresponding operations during the driving process. In addition, due to individual differences and state fluctuations among drivers, a single road feel feedback mode is not easy to meet the driving needs of different drivers, affecting the driving experience.

[0073] Therefore, in some embodiments, the road feel simulation device 100 of the present invention is applied to a steer-by-wire system, and can simulate the road feel required in the steer-by-wire system. Specifically, the axial vibration generated by the liquid hitting the first baffle 21 is transmitted to the steering wheel 30, and the road excitation feedback of the vehicle during straight-line driving can be realized. The tangential vibration generated by the liquid hitting the second baffle 22 is transmitted to the steering wheel 30, and the road excitation feedback of the vehicle during the steering process can be realized, and a more realistic road feel feedback of the steering wheel 30 during driving can be realized, which can meet the driving needs of different drivers and realize the advantages of multiple modes, realistic feedback, and adjustable magnitude.

[0074] Therefore, during vehicle driving, the first road feel simulation module can provide circumferential rotation damping force for the steering wheel 30, and the second road feel simulation module 10 can provide axial vibration damping force and circumferential vibration damping force for the steering wheel 30, which is convenient for the driver to judge the vehicle status, determine the cornering angle and vehicle speed, judge the grip of the wheel, etc., to meet the required driving feedback needs and ensure the driving safety and comfort of the vehicle.

[0075] According to some embodiments of the present invention, Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, the baffle body 20 extends along the length direction of the shell 111 , and both ends of the baffle body 20 in the length direction are respectively connected to the shell 111 , which can meet the connection requirements of the baffle assembly 112 and the shell 111 .

[0076] In addition, if Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, there are multiple second baffles 22, and the multiple second baffles 22 are spaced apart along the circumferential direction of the baffle body 20. One end of each second baffle 22 in the width direction is connected to the baffle body 20, and the other end of each second baffle 22 in the width direction extends radially outwardly along the baffle body 20, which can reduce the space occupied by the second baffle 22 in the circumferential direction of the baffle body 20, ensure a compact structure, and facilitate the impact of the liquid on the second baffle 22. In addition, the multiple second baffles 22 can increase the probability of the liquid colliding with the second baffle 22, ensuring a more uniform impact, so that the road feel simulation device 100 can perform a more accurate and reliable road feel simulation.

[0077] At the same time, if Figure 5 , Figure 7 and Figure 8 As shown, a first baffle 21 is provided between at least two adjacent second baffles 22 to facilitate the impact of liquid on the first baffle 21 and meet the impact requirements of the liquid with the first baffle 21 and the second baffle 22. The baffle assembly 112 has a simple structure and is easy to process and manufacture.

[0078] In the embodiment of the present invention, the number of the second baffles 22 can be flexibly set according to actual conditions. For example, the second baffles 22 can be Figure 8 Eight are shown, but two, three, four, five, six, seven, nine or more may also be provided, all of which are within the scope of protection of the present invention.

[0079] In some embodiments, there may be eight second baffles 22 , and the eight second baffles 22 can be roughly formed into a “M” shape, ensuring that the multiple first baffles 21 are compactly structured on the baffle body 20 , making the impact more uniform.

[0080] In some embodiments of the present invention, Figure 8 As shown, there are multiple first baffles 21 between at least two partially adjacent second baffles 22, and the multiple first baffles 21 are arranged at intervals along the length direction of the shell 111. The multiple first baffles 21 can increase the structural strength of the second baffle 22 to avoid deformation caused by the collision between the liquid and the second baffle 22. At the same time, the multiple first baffles 21 can increase the probability of collision between the liquid and the first baffle 21, ensuring a more uniform collision, so that the road feel simulation device 100 can perform a more accurate and reliable road feel simulation.

[0081] In the embodiment of the present invention, the number of the first baffles 21 between at least two adjacent second baffles 22 can be flexibly set according to actual conditions. For example, the first baffles 21 between at least two adjacent second baffles 22 can be as follows: Figure 8 Three are shown, but two, four, five, six or more may also be provided, all of which are within the protection scope of the present invention.

[0082] According to some embodiments of the present invention, the total area of ​​the two surfaces of all the first baffles 21 in the thickness direction is smaller than the total area of ​​the two surfaces of all the second baffles 22 in the thickness direction, so that the axial vibration amplitude generated by the liquid hitting the first baffles 21 is smaller than the tangential vibration amplitude generated by the liquid hitting the second baffles 22, thereby reducing the tangential vibration generated by the road feel simulation device 100. While being able to provide the required road feel feedback, it is able to ensure the vibration isolation comfort of the wire-controlled steering and ensure the driver's driving experience.

[0083] In some embodiments, there are multiple second baffles 22 and multiple first baffles 21, and the total area of ​​the two surfaces in the thickness direction of the multiple first baffles 21 is smaller than the total area of ​​the two surfaces in the thickness direction of the multiple second baffles 22, so that the axial vibration amplitude generated by the liquid hitting the multiple first baffles 21 is smaller than the tangential vibration amplitude generated by the liquid hitting the multiple second baffles 22, thereby reducing the tangential vibration generated by the road feel simulation device 100, while being able to provide the required road feel feedback, and ensuring the comfort of wire-controlled steering vibration isolation, ensuring the driver's driving experience.

[0084] In some embodiments of the present invention, Figure 8 As shown, there are multiple (greater than or equal to two) first baffles 21, and the multiple first baffles 21 are spaced apart along the length direction of the baffle body 20. The multiple first baffles 21 can increase the probability of collision between the liquid and the first baffle 21, ensuring a more uniform collision, so that the road feel simulation device 100 can perform a more accurate and reliable road feel simulation.

[0085] According to some embodiments of the present invention, a plurality of (greater than or equal to two) impact particles are provided in the accommodating chamber 113. When the driving component 12 drives the liquid in the accommodating chamber 113 to flow to impact the first baffle 21, the liquid can drive the impact particles mixed in the liquid to move, thereby causing the impact particles to collide with the first baffle 21. This can make the generated vibration more realistic and the simulated vibration of the road feel simulation device 100 more reliable, thereby achieving more realistic road feel feedback during vehicle driving.

[0086] In some embodiments where the baffle assembly 112 includes the second baffle 22, when the driving assembly 12 drives the liquid in the accommodating chamber 113 to flow to impact the second baffle 22, the liquid can drive the impact particles mixed in the liquid to move, so that the impact particles collide with the second baffle 22, which can make the generated vibration more realistic and the simulated vibration of the road feel simulation device 100 more reliable, thereby achieving more realistic road feel feedback during vehicle driving.

[0087] In some embodiments of the present invention, Figure 4 and Figure 8 As shown, the baffle body 20 extends along the length direction of the housing 111, and the baffle body 20 is provided with a flow channel 201 and a flow hole 202. The flow channel 201 extends along the length direction of the baffle body 20, and the flow hole 202 is connected with the flow channel 201 and the accommodating cavity 113. The flow hole 202 is located at one end of the baffle body 20 away from the steering wheel 30 (for example Figure 8 ), so that the liquid can flow between the flow channel 201 and the accommodating chamber 113 through the flow hole 202.

[0088] At the same time, if Figure 8 As shown, the second road feel simulation module 10 further includes a first drive pump 40, which is disposed in the accommodating cavity 113 and is located at one end of the baffle body 20 close to the steering wheel 30 (eg Figure 8 The inlet of the first driving pump 40 is connected to an end of the flow channel 201 close to the steering wheel 30.

[0089] The first driving pump 40 can drive the liquid and the impact particles to enter the flow channel 201 through the flow hole 202, and then flow from the flow channel 201 to the accommodating chamber 113 through the outlet of the first driving pump 40, so as to realize the flow of the liquid between the flow channel 201 and the accommodating chamber 113, and realize the reciprocating circulation of the liquid, so that the impact particles can move under the driving action of the first driving pump 40, avoiding the problem of uneven distribution of the impact particles in the liquid under the action of gravity, ensuring that the impact particles are evenly distributed in the liquid, ensuring reliable impact on the first baffle 21, and meeting the required road sense feedback requirements. For example, the first driving pump 40 can be a liquid circulation pump.

[0090] In some embodiments, in the working gap between two adjacent times when the driving component 12 drives the liquid in the accommodating chamber 113 to flow and impact the first baffle 21, the first driving pump 40 drives the liquid and the impact particles to enter the flow channel 201 through the flow hole 202 and then flow to the accommodating chamber 113, thereby preventing the driving component 12 and the first driving pump 40 from working at the same time and affecting the operation of the vibration generating component 11, thereby ensuring that the road feel simulation device 100 simulates the vibration more accurately.

[0091] In some embodiments, the first driving pump 40 can be fixed to the baffle body 20 by fasteners, ensuring that the first driving pump 40 is reliably fixed to the baffle body 20 and is easy to assemble and disassemble. For example, the fasteners can be bolts or the like.

[0092] In some embodiments, there may be multiple flow holes 202, which are spaced apart along the circumferential direction of the baffle body 20. The multiple flow holes 202 can increase the amount of liquid entering the flow channel 201, facilitate the flow of liquid in the flow channel 201 and the accommodating cavity 113, and ensure smooth flow of liquid.

[0093] In the embodiment of the present invention, the number of the flow holes 202 can be flexibly set according to actual conditions. For example, the flow holes 202 can be as follows: Figure 8 Four are shown, but there may be two, three, five, six or more, all of which are within the protection scope of the present invention.

[0094] In some embodiments, there may be four flow holes 202 , which are arranged in a 90° array on the baffle body 20 , so as to facilitate the processing and manufacturing of the flow holes 202 and ensure smooth flow of liquid.

[0095] According to some embodiments of the present invention, Figure 4-Figure 7 As shown, the housing 111 includes a housing body 50, a first connecting section 51 and a second connecting section 52. The housing body 50 has a first cavity 501. The first connecting section 51 and the second connecting section 52 are respectively connected to the housing body 50 in the length direction (for example Figure 4 The first connecting section 51 and the second connecting section 52 respectively have a second cavity 511 and a third cavity 521, and the second cavity 511 and the third cavity 521 are both connected to the first cavity 501, so that the first cavity 501, the second cavity 511 and the third cavity 521 together form a accommodating cavity 113, which can realize the accommodating cavity 113 to accommodate liquid, and the structure of the shell 111 is simple, which is convenient for processing and manufacturing.

[0096] In addition, if Figure 4-Figure 7 As shown, the cross-sectional areas of the first cavity 501 and the second cavity 511 gradually decrease in the direction away from each other, so that the first cavity 501 and the second cavity 511 can be roughly formed into a conical cavity, and the liquid can smoothly transition in the first cavity 501 and the second cavity 511, which is convenient for liquid reflux, and can avoid the problem of excess feedback vibration caused by liquid flowing toward the bend and affecting normal feedback, thereby ensuring that the road feel simulation device 100 simulates vibration more accurately.

[0097] In some embodiments, the housing 111 may be a nylon piece, so that the housing 111 has good structural strength, is easy to process, and can avoid noise and other problems caused by collision between the liquid and the housing 111. For example, the housing 111 may be a hard nylon piece.

[0098] In some embodiments, the shell body 50 and the first connecting section 51 and the second connecting section 52 can be connected by gluing to ensure that the shell body 50, the first connecting section 51 and the second connecting section 52 are reliably connected, the structure is simple, and it is easy to process, manufacture and assemble, and can meet the required sealing requirements to avoid leakage and other problems.

[0099] In some embodiments, Figure 4 As shown, the two ends of the baffle body 20 in the length direction can be connected to the first connecting section 51 and the second connecting section 52 respectively to ensure that the baffle assembly 112 is reliably fixed in the accommodating cavity 113 and avoid problems such as the baffle assembly 112 being skewed in the accommodating cavity 113.

[0100] In some embodiments, the two ends of the baffle body 20 in the length direction are connected to the first connecting section 51 and the second connecting section 52 by gluing to ensure a reliable connection, facilitate assembly, and meet the required sealing requirements to avoid leakage and other problems.

[0101] In some embodiments of the present invention, Figure 2-Figure 4 As shown, the second road feel simulation module 10 also includes a housing 60, and the vibration generating component 11 and the driving component 12 are arranged in the housing 60. The housing 60 can protect the vibration generating component 11 and the driving component 12 to avoid damage caused by exposure of the vibration generating component 11 and the driving component 12, which is beneficial to prolonging the service life of the vibration generating component 11 and the driving component 12.

[0102] According to some embodiments of the present invention, Figure 4 As shown, the road feeling simulation device 100 further includes a connecting support 70, the length direction of the connecting support 70 (for example Figure 4 One end of the connecting support 70 in the up and down direction shown in the figure is connected to at least one of the baffle assembly 112 and the shell 111, that is, one end of the connecting support 70 in the length direction can be connected to the baffle assembly 112, or one end of the connecting support 70 in the length direction can be connected to the shell 111, or one end of the connecting support 70 in the length direction can be connected to the baffle assembly 112 and the shell 111, and the other end of the connecting support 70 in the length direction is connected to the steering wheel 30, which can realize the connection between the connecting support 70 and the second road feel simulation module 10 and the steering wheel 30, so that the steering wheel 30 can be connected to the second road feel simulation module 10 through the connecting support 70, ensuring a reliable connection, and a simple structure, which is convenient for processing, manufacturing and assembly.

[0103] In some embodiments, the connecting bracket 70 can be connected to at least one of the baffle assembly 112 and the shell 111 by threads, that is, the connecting bracket 70 can be connected to the baffle assembly 112 by threads, or the connecting bracket 70 can be connected to the shell 111 by threads, or the connecting bracket 70 can be connected to the baffle assembly 112 and the shell 111 by threads, to ensure reliable connection and facilitate assembly and disassembly.

[0104] In some embodiments, the baffle body 20 is provided with a flow channel 201 extending along the length direction of the baffle body 20, such as Figure 4 As shown, the flow channel 201 is formed as a through hole extending along the length direction of the baffle body 20, and one end of the connecting support 70 in the length direction can extend into the flow channel 201 to realize the connection between the connecting support 70 and the baffle assembly 112. At the same time, the flow channel 201 can be blocked by the connecting support 70 to avoid problems such as liquid leakage, and the structure is simple, which is convenient for processing, manufacturing and assembly.

[0105] In some embodiments of the present invention, Figure 2 and Figure 4 As shown, the first road feeling simulation module is an encoder 80, a mounting hole 31 is provided on the steering wheel 30, one end of the connecting support 70 extends into the mounting hole 31, and an encoder 80 is provided between the outer peripheral wall of the connecting support 70 and the hole wall of the mounting hole 31, so as to facilitate the connection between the connecting support 70 and the steering wheel 30. At the same time, the encoder 80 can realize the basic damping force feedback when the steering wheel 30 is turned and the output of the wire control steering signal such as the rotation angle and the rotation speed, so as to meet the signal transmission requirements and the required basic damping force requirements, so that the driver can experience a more realistic driving feeling during the steering process. For example, the encoder 80 can be a ring damping encoder 80.

[0106] In some embodiments where the baffle assembly 112 further includes a second baffle 22, such as Figure 4 As shown, the axial vibration generated by the liquid hitting the first baffle 21 is transmitted to the steering wheel 30, which can realize the road excitation feedback of the vehicle during straight-line driving. The tangential vibration generated by the liquid hitting the second baffle 22 is transmitted to the steering wheel 30, which can realize the road excitation feedback of the vehicle during the steering process. At the same time, the basic damping force feedback when the steering wheel 30 is turned can be realized through the encoder 80, so as to realize more realistic road feel feedback of the steering wheel 30 during driving, which can meet the driving needs of different drivers.

[0107] In some embodiments, the encoder 80 includes an outer ring and an inner ring, the inner ring is arranged inside the outer ring, the hole wall of the mounting hole 31 is in contact with the outer peripheral wall of the outer ring, and the inner peripheral wall of the inner ring is in contact with the outer peripheral wall of the connecting support 70, thereby realizing the connection between the encoder 80 and the steering wheel 30 and the connecting support 70, ensuring that the encoder 80 is reliably fixed between the steering wheel 30 and the connecting support 70, and facilitating the transmission of vibrations on the connecting support 70 to the steering wheel 30 through the encoder 80.

[0108] In some embodiments, the hole wall of the mounting hole 31 and the outer peripheral wall of the outer ring can be connected by interference fit and / or gluing, so as to ensure that the outer ring and the steering wheel 30 are reliably connected and easy to assemble.

[0109] In some embodiments, the inner circumferential wall of the inner ring and the outer circumferential wall of the connecting support 70 can be connected by interference fit and / or gluing to ensure that the inner ring and the connecting support 70 are reliably connected and easy to assemble.

[0110] According to some embodiments of the present invention, Figure 4 As shown, the connecting support 70 is provided with an abutment portion 71, which extends along the circumferential direction of the connecting support 70. The abutment portion 71 is located on the side of the steering wheel 30 facing the housing 111 (for example, Figure 4 ), and the abutting portion 71 abuts against the steering wheel 30. Thus, the abutting portion 71 can limit the position of the steering wheel 30, thereby preventing the steering wheel 30 from moving on the connecting support 70, and facilitates the transmission of the axial vibration generated by the second road feeling simulation module 10 to the steering wheel 30 through the abutting portion 71, thereby ensuring more accurate vibration transmission.

[0111] In some embodiments of the present invention, Figure 4 As shown, the side of the housing 60 close to the steering wheel 30 (eg Figure 4 The upper side shown in FIG. 1 has an open opening 61, a centering bushing 62 is arranged in the open opening 61, and the connecting support 70 is passed through the centering bushing 62, so that the centering bushing 62 can limit the position of the connecting support 70 to prevent the connecting support 70 from moving. At the same time, when the vibration generating component 11 generates axial vibration, the centering bushing 62 can prevent the connecting support 70 from axial movement, thereby limiting the position of the vibration generating component 11 and ensuring that the position of the vibration generating component 11 is reliable.

[0112] In some embodiments, the connecting support 70 and the centering bushing 62 can be fixed by interference fit and / or vulcanization to ensure that the connecting support 70 and the centering bushing 62 are securely fixed, avoid displacement, and facilitate assembly.

[0113] In some embodiments, the housing 60 and the centering bushing 62 may be fixed by wedging and / or gluing to ensure that the housing 60 and the centering bushing 62 are securely fixed, avoid displacement, and facilitate assembly.

[0114] According to some embodiments of the present invention, Figure 4 As shown, a weakening hole 63 is provided on the centering bushing 62, and the weakening hole 63 and the connecting support 70 are arranged at intervals. The weakening hole 63 can be used to weaken the structure of the centering bushing 62, thereby reducing the attenuation effect of the centering bushing 62 on vibration. While ensuring that the centering bushing 62 is fixed to the connecting support 70, it can ensure that the vibration transmission is more reliable.

[0115] In the embodiment of the present invention, the specific structure of the driving assembly 12 can be set according to actual conditions.

[0116] For example, in some embodiments, Figure 4 and Figure 5 As shown, the liquid contained in the accommodating chamber 113 may be a magnetorheological fluid, which is a fluid with controllable fluidity. The magnetorheological fluid can produce different degrees of changes in physical properties (such as viscosity, fluidity, etc.) under the action of a magnetic field. Therefore, the driving component 12 may include an electromagnet 121, which is arranged in the housing 60 and outside the housing 111. The electromagnet 121 is arranged around the housing 111, and the electromagnet 121 is located in the length direction of the housing 111 (for example Figure 4 The end portion of the upper and lower directions shown in FIG.

[0117] By energizing the electromagnet 121, the electromagnet 121 can generate a magnetic field. By utilizing the physical properties of the magnetorheological fluid under the action of the magnetic field, the magnetic field will control the flow of the magnetorheological fluid, thereby driving the magnetorheological fluid to collide with the first baffle 21, making the control simple and the response quick. By controlling the magnetic field, different magnetic fields will control the different fluidities of the magnetorheological fluid, thereby achieving control of the magnetorheological fluid and being able to generate vibrations with controllable direction, controllable force, and controllable frequency to meet the different vibration requirements.

[0118] In some embodiments, Figure 4 and Figure 5 As shown, the electromagnet 121 includes an iron core 122 and a coil 123. The iron core 122 is arranged around the housing 111, and the coil 123 is wound around the iron core 122. When the coil 123 is energized, the electromagnet 121 can generate a magnetic field, so that the structure of the electromagnet 121 is simple, which is conducive to reducing production costs. For example, the coil 123 can be a copper part, and the iron core 122 can be made of silicon steel.

[0119] For example, when the electromagnet 121 is located at the upper end of the shell 111, when axial vibration from bottom to top is required, the coil 123 passes a sinusoidal current to make the electromagnet 121 magnetic, so that the electromagnet 121 can attract the magnetic particles in the magnetorheological fluid to move toward the electromagnet 121, thereby making the magnetorheological fluid flow upward, so that the liquid can hit the first baffle 21, and generate the required axial vibration.

[0120] In the embodiment of the present invention, the number of turns of the coil 123 can be set according to actual conditions. For example, the number of turns of the coil 123 can be changed according to the requirements of the magnetic field strength to meet different usage requirements.

[0121] In some embodiments, the baffle assembly 112 may be a nylon member. The nylon baffle assembly 112 can avoid being affected by the magnetic field, ensure that the magnetorheological fluid can reliably impact the first baffle 21, and avoid problems such as abnormal sound caused by the magnetorheological fluid impacting the baffle assembly 112, thereby effectively reducing noise. For example, the baffle assembly 112 may be a single-layer hard nylon member.

[0122] In some embodiments where a plurality of impact particles are provided in the accommodating cavity 113, the impact particles may be nylon parts, and the impact particles of the nylon parts can avoid being affected by the magnetic field, ensuring that the impact particles impact the first baffle 21 under the drive of the magnetorheological fluid, ensuring more accurate vibration generation, and avoiding problems such as abnormal sound caused by the impact particles impacting the baffle assembly 112, thereby effectively reducing noise. For example, the impact particles may be hard nylon parts.

[0123] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, there may be two electromagnets 121, and the two electromagnets 121 are spaced apart in the length direction of the shell 111, and the two electromagnets 121 are respectively located at the two ends of the length direction of the shell 111. The two electromagnets 121 can further accelerate the driving of the magnetorheological fluid, so that the flow effect of the magnetorheological fluid is better, ensuring more accurate driving of the magnetorheological fluid, thereby ensuring more precise vibration.

[0124] According to some embodiments of the present invention, Figure 4 and Figure 5 As shown, a fixing seat 64 is provided on the inner wall surface of the housing 60, and the second road sense simulation module 10 also includes a fixing member 65, which is connected to the fixing seat 64 and the electromagnet 121, so that the electromagnet 121 can be connected to the fixing seat 64 through the fixing member 65, ensuring that the electromagnet 121 is reliably fixed on the housing 60, avoiding problems such as movement, and facilitating assembly.

[0125] In some embodiments, the fixing member 65 and the fixing seat 64 are connected by fasteners to ensure that the fixing member 65 and the fixing seat 64 are reliably connected and are easy to assemble and disassemble.

[0126] In some embodiments, the fixing member 65 may be a nylon member, so that the fixing member 65 has good structural strength, is easy to process, and avoids affecting the magnetic field. For example, the fixing member 65 may be a hard nylon member.

[0127] In some embodiments, the fixing seat 64 may be a nylon piece, so that the fixing seat 64 can have good structural strength, be easy to process, and avoid affecting the magnetic field. For example, the fixing seat 64 may be a hard nylon piece.

[0128] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the end of the vibration generating assembly 11 away from the steering wheel 30 (eg Figure 4 The lower end of the vibration generating assembly 11 (shown in FIG. 1 ) is connected to the housing 60 through a fixed bushing 66, ensuring that the vibration generating assembly 11 is fixed reliably on the housing 60, and can limit the end of the vibration generating assembly 11 away from the steering wheel 30 to prevent the vibration generating assembly 11 from moving and other problems. At the same time, when the vibration generating assembly 11 generates vibration, the fixed bushing 66 can absorb the vibration to prevent the vibration from being transmitted to the housing 60, ensuring that the road feel simulation device 100 is fixed reliably. For example, the fixed bushing 66 can be a rubber member.

[0130] In addition, if Figure 4 and Figure 5 As shown, the side of the second fixing base 642 facing the vibration generating component 11 (for example Figure 4 A fixed bushing 66 is provided on the upper side (as shown in the figure), and the end of the vibration generating component 11 away from the steering wheel 30 is connected to the fixed bushing 66, which facilitates the connection between the vibration generating component 11 and the fixed bushing 66, and makes the structure of the shell 111 simple, which is convenient for processing and manufacturing, and is conducive to reducing production costs.

[0131] In some embodiments, the end of the vibration generating assembly 11 away from the steering wheel 30 is connected to the fixed bushing 66 by a thread, so as to ensure that the vibration generating assembly 11 and the fixed bushing 66 are reliably connected and easy to assemble and disassemble.

[0132] In some embodiments, the second fixing seat 642 and the fixing bushing 66 can be connected by gluing to ensure that the second fixing seat 642 and the fixing bushing 66 are reliably fixed, and the structure is simple and easy to assemble, which is conducive to improving assembly efficiency.

[0133] In some embodiments, Figure 5 As shown, there may be a plurality of first fixing seats 641, and the plurality of first fixing seats 641 are spaced apart along the circumferential direction of the shell 111. The plurality of first fixing seats 641 can support and fix a plurality of different positions of the electromagnet 121 located at one end of the shell 111 close to the steering wheel 30, thereby ensuring that the position of the electromagnet 121 located at one end of the shell 111 close to the steering wheel 30 is reliably fixed and avoiding problems such as skewing.

[0134] In the embodiment of the present invention, the number of the first fixing seats 641 can be flexibly set according to actual conditions. For example, the first fixing seats 641 can be Figure 5 Four are shown, but there may be two, three, five, six or more, all of which are within the protection scope of the present invention.

[0135] In some embodiments, Figure 5 As shown, there may be a plurality of second fixing seats 642, and the plurality of second fixing seats 642 are spaced apart along the circumferential direction of the shell 111. The plurality of second fixing seats 642 can support and fix the electromagnet 121 at a plurality of different positions located at the end of the shell 111 away from the steering wheel 30, thereby ensuring that the position of the electromagnet 121 at the end of the shell 111 away from the steering wheel 30 is reliably fixed and avoiding problems such as skewing.

[0136] In the embodiment of the present invention, the number of the second fixing seats 642 can be flexibly set according to actual conditions.

Thus, the second drive pump and the nozzle can drive the liquid to flow in the accommodating chamber 113, so that the liquid can collide with the first baffle 21. The drive assembly 12 has a simple structure and is easy to control, which is conducive to reducing production costs. At the same time, by controlling the duration and strength of the nozzle, the effect of controlling the directional and constant speed flow of the liquid in the accommodating chamber 113 can be achieved, meeting the requirements of different vibrations.

The first baffle 21 is arranged on the baffle body 20 and is perpendicular to the length direction of the housing 111. The second baffle 22 is arranged on the baffle body 20 and extends along the length direction of the housing 111. The second baffle 22 is parallel to the length direction of the housing 111. A plurality of impact particles are arranged in the accommodating cavity 113. Two electromagnets 121 are symmetrically arranged in the length direction of the housing 111. The electromagnet 121 includes a coil 123 and an iron core 122. After the coil 123 is energized, the direction, magnitude and action time of the magnetic field are controlled by the current in the coil 123.

[0149] When counterclockwise tangential vibration is required, the current passing through the coil 123 is a sinusoidal current, the electromagnet 121 located at the end of the shell 111 away from the steering wheel 30 is energized first, and the electromagnet 121 located at the end of the shell 111 close to the steering wheel 30 is energized later, and the phase difference between the two sets of current waveforms is N·π / 2.

[0150] When the electromagnet 121 at the end of the shell 111 away from the steering wheel 30 is magnetic, the electromagnet 121 at the end of the shell 111 close to the steering wheel 30 is non-magnetic, and the magnetorheological fluid in the accommodating cavity 113 is squeezed toward the cavity wall of the accommodating cavity 113 under the combined force of its own gravity and the axial magnetic force, so that the magnetorheological fluid can flow approximately tangentially along the cavity wall of the accommodating cavity 113; then, when the electromagnet 121 at the end of the shell 111 away from the steering wheel 30 is non-magnetic, the magnetorheological fluid in the accommodating cavity 113 is squeezed toward the cavity wall of the accommodating cavity 113 under the combined force of its own gravity and the axial magnetic force, so that the magnetorheological fluid can flow approximately tangentially along the cavity wall of the accommodating cavity 113; The electromagnetic force at one end of 111 close to the steering wheel 30 is magnetic, and the direction of the magnetic force is reversed, so that the flow of the magnetorheological fluid that is blocked by the cavity wall of the accommodating cavity 113 is strengthened, and the magnetorheological fluid flows more rapidly along the cavity wall of the accommodating cavity 113 in an approximately tangential direction, and while the magnetorheological fluid flows, the impact particles can move with the flow of the magnetorheological fluid, that is, the impact particles will produce a movement in the same direction as the flow of the magnetorheological fluid, so that the impact particles will collide with the second baffle 22, generating the required tangential vibration. In addition, when the N value of the phase difference N·π / 2 is larger, the tangential flow rate of the magnetorheological fluid is faster, which can meet different control requirements.

[0151] When it is necessary to generate axial vibration from bottom to top, the current passing through the coil 123 is a sinusoidal current, and the electromagnet 121 located at the end of the shell 111 close to the steering wheel 30 is energized first, and the electromagnet 121 located at the end of the shell 111 away from the steering wheel 30 is energized later, and the phase difference between the two sets of current waveforms is -N·π, so that the magnetic field directions generated by the electromagnet 121 located at the end of the shell 111 close to the steering wheel 30 and the electromagnet 121 located at the end of the shell 111 away from the steering wheel 30 are opposite.

[0152] When the electromagnet 121 at the end of the shell 111 close to the steering wheel 30 is magnetic, the electromagnet 121 at the end of the shell 111 close to the steering wheel 30 can attract the magnetic particles in the magnetorheological fluid, so that the magnetorheological fluid can flow in the direction close to the steering wheel 30, and make these magnetic particles carry the charge opposite to the magnetic field; then, after -N·π cycles, when the electromagnet 121 at the end of the shell 111 away from the steering wheel 30 is magnetic, the charge of the magnetic particles in the magnetorheological fluid is opposite to that of the electromagnet 121 at the end of the shell 111 close to the steering wheel 30. The magnetic field of the electromagnet 121 at the end of the housing 111 away from the steering wheel 30 is the same. Since like charges repel each other, the combined force of the magnetorheological fluid will overcome gravity and flow toward the direction close to the steering wheel 30. The magnetorheological fluid flows faster toward the direction close to the steering wheel 30, and while the magnetorheological fluid flows, the impact particles can move with the flow of the magnetorheological fluid, that is, the impact particles will produce a movement in the same direction as the flow of the magnetorheological fluid, so that the impact particles will collide with the first baffle 21, generating the required axial vibration. In addition, when the N value of the phase difference -N·π is larger, the axial flow rate of the magnetorheological fluid is faster, which can meet different control requirements.

[0153] In some embodiments, based on the driver's test of the road feel feedback characteristic action, by controlling the electromagnet, different vibration directions of the road feel feedback characteristics can be achieved, different feedback requirements can be met, and the driver's driving experience can be improved.

[0154] In some embodiments where the road feel simulation device 100 further includes a first drive pump 40, when the road feel simulation device 100 simulates a road feel feedback feature, multiple tangential vibrations or multiple axial vibrations are required to meet the simulation requirements of the required road feel feedback feature, and between two adjacent tangential vibrations or two adjacent axial vibrations, the first drive pump 40 drives the liquid and impact particles from the flow hole 202 into the flow channel 201 and then flows to the containing chamber 113, which can make the impact particles more uniform in the containing chamber 113, facilitate the next tangential vibration or axial vibration, and ensure that the road feel simulation device 100 simulates the vibration more accurately.

[0155] In some embodiments, Figure 1 As shown, the vehicle also includes a front windshield 91 and a cabin floor 94. The front windshield 91 is located in front of the center console 90. The center console 90 is located above the cabin floor 94. The center console 90 and the cabin floor 94 define a cabin foot space 93. By tilting the second road feel simulation module 10 on the center console 90, it is possible to avoid the second road feel simulation module 10 occupying the cabin foot space 93, and the size of the cabin foot space 93 can be increased, which is beneficial to improving the driver's driving experience.

[0156] In addition, if Figure 1 As shown, a dashboard 92 is also provided on the center console 90, through which the working status of the vehicle can be reflected, so that the driver can monitor the vehicle status at any time, control the vehicle conveniently, and ensure driving safety.
