Description

TECHNICAL FIELD

[0001] The present disclosure relates to a vehicle haptics system. Aspects of the invention relate to a vehicle haptics system. BACKGROUND

[0002] Vehicles can include massage systems that massage the back or feet of a user. Where massage systems are employed in vehicles, these systems typically include pneumatic systems, such as inflatable airbags. These systems are typically not suitable for being disposed in the footwell or floor portion of a vehicle. For example, it has been found that the use of pneumatic systems is ineffective in delivering a massage sensation when the massage system is not in direct contact with the user or in close proximity to the user. This limitation therefore restricts the location of the system and the choice of soft goods material in the corresponding area of the vehicle. By way of example, the use of known foot massage systems relies on the user removing their footwear, which can be uncomfortable for some users. Additionally, pneumatic systems are typically too large to be positioned within the footwell or floor portion of a vehicle. As a result, known foot massage systems can instead be disposed in a seat in front of the user. This presents a range of disadvantages. For example, in order to receive a massage sensation, the user of the massage system must raise their feet in order to come into contact with the massage system. Raising the feet of a user can be difficult for users with limited mobility and restricts use to when the vehicle is stationary, to avoid potential injury when moving. Furthermore, as the massage system is disposed in a seat opposite to the user, only passengers in the rear vehicle seats can experience the massage sensation.

[0003] It is an object of the present invention to address one or more of the disadvantages associated with the prior art. SUMMARY

[0004] Aspects and embodiments of the invention provide a vehicle haptics system, a footwell or floor portion of a vehicle and a vehicle as claimed in the appended claims.

[0005] According to an aspect of the invention, there is provided a vehicle haptics system for vibrating at least one foot of an occupant of a vehicle, the vehicle haptics system comprising at least one foot haptics module for positioning in a footwell or floor portion of the vehicle, the at least one foot haptics module comprising at least one haptics transducer, wherein the at least one haptics transducer is configured to receive a haptics signal and generate a vibration in accordance with the haptics signal.

[0006] Advantageously, the haptic transducer allows the vehicle haptics system to be more compact than known vehicle haptics systems that instead use, for example, pneumatic systems as massaging devices. Thus, the more compact system can be positioned within the footwell or floor portion of the vehicle and thus be more accessible to more occupants of the vehicle. Additionally, surprisingly, the use of haptic transducers is more effective in providing a massaging sensation through the typical vehicle floor than known massaging devices, similarly allowing the vehicle haptics system to be positioned within the footwell or floor portion of the vehicle.

[0007] In embodiments, the vehicle haptics system comprises a control system coupled to the at least one haptic transducer, wherein the control system is configured to output a haptic signal to actuate the at least one haptic transducer.

[0008] In embodiments, the at least one haptic transducer comprises a plurality of haptic transducers. Advantageously, the plurality of haptic transducers can vibrate different feet and / or different parts of the feet of a user of the vehicle haptics system.

[0009] In embodiments, a first haptic transducer of the plurality of haptic transducers is configured to receive a first haptic signal and generate vibrations according to the first haptic signal, and wherein a second haptic transducer of the plurality of haptic transducers is configured to receive a second haptic signal different from the first haptic signal and generate vibrations according to the second haptic signal. That is, the vibrations communicated from the first haptic transducer and the second haptic transducer, and the massaging sensation communicated thereby, are different from one another. Advantageously, this allows targeted haptic signals to be sent to different feet and / or different parts of the feet of a user of the vehicle haptics system for targeted activation.

[0010] In embodiments, the at least one foot haptics module comprises a profile having a length and a width, wherein each haptic transducer of the plurality of haptic transducers is offset relative to other haptic transducers of the plurality of haptic transducers along the length and / or width of the profile of the at least one foot haptics module. That is, the haptic transducers are spaced apart to target different feet and / or different parts of the feet of a user. Advantageously, each haptic transducer can provide a different massaging sensation to different feet and / or different parts of the feet of a user of the vehicle haptics system.

[0011] In one embodiment, the at least one foot tactile module is configured to be positioned within the foot pedal or floor portion of the vehicle, such that the length of its profile extends laterally in the forward viewing direction of the user of the vehicle tactile system. That is, the at least one foot tactile module is sized to fit within the foot pedal or floor portion of the vehicle. Therefore, the vehicle tactile system overcomes the disadvantages of known systems because it can be utilized by more vehicle occupants, who do not need to raise their legs to operate the system, and it can be used while the vehicle is in motion.

[0012] In one embodiment, the plurality of tactile transducers include: a first group of at least one tactile transducer for vibrating a first foot of a user of the vehicle's tactile system; and a second group of at least one tactile transducer for vibrating a second foot of the user of the vehicle's tactile system. Advantageously, individual vibrations, and thus the massage sensation, can be transmitted to the first and second feet of the user of the vehicle's tactile system. This allows targeted vibrations to be sent to, for example, each foot, to achieve a spatial tactile effect, wherein the vibration or vibration pattern “moves” from one foot to the other.

[0013] In one implementation, the control system is configured to independently control at least one tactile transducer in the first group and at least one tactile transducer in the second group. Advantageously, individual tactile signals can be sent to at least one tactile transducer in the first group and at least one tactile transducer in the second group to individually activate each foot when needed.

[0014] In one embodiment, the at least one tactile transducer of the first group is offset relative to the at least one tactile transducer of the second group along the length of the outline of the at least one foot tactile module. That is, the first and second groups are spaced laterally in the user's forward viewing direction, such that the tactile transducers in each group correspond to or are close to the corresponding foot.

[0015] In one embodiment, the first group of at least one tactile transducer and the second group of at least one tactile transducer each include a front tactile transducer positioned close to the user's forefoot of the vehicle's tactile system. That is, each group includes a front tactile transducer positioned to target the user's forefoot. Advantageously, the user's forefoot can be activated by vibration, and thereby activated using a massage sensation specifically targeting or best suited to the forefoot area.

[0016] In one embodiment, the first group of at least one tactile transducer and the second group of at least one tactile transducer each include a rear tactile transducer positioned close to the user's rear foot in relation to the vehicle's tactile system. That is, each group includes a rear tactile transducer positioned to target the user's rear foot. Advantageously, the user's rear foot can be activated by vibration, and thereby activated using a massage sensation specifically targeting or best suited to the rear foot area.

[0017] In one embodiment, the front and rear tactile transducers of each of the first group of at least one tactile transducer and the second group of at least one tactile transducer are offset along the width of at least one foot tactile module.

[0018] In this embodiment, the control system is configured to output a first tactile signal to actuate the front tactile transducers of the first and second groups, and to output a second tactile signal to actuate the rear tactile transducers of the first and second groups. That is, the front and rear tactile transducers of both the first and second groups can be controlled independently of each other. Advantageously, each of the forefoot and hindfoot regions can be individually and specifically subjected to vibrations best suited to each region.

[0019] In this implementation, the control system is configured to independently control the front tactile transducer and the rear tactile transducer.

[0020] In one embodiment, the control system is configured to actuate the first and second groups of front tactile transducers at a frequency of 60 Hz to 150 Hz based on a first tactile signal. Advantageously, it has been found that the occupant's forefeet are particularly receptive to vibrations in the frequency range of 60 Hz to 150 Hz, thereby maximizing the massage sensation.

[0021] In this implementation, the control system is configured to actuate the first and second sets of rear tactile transducers at a frequency of 25 Hz to 60 Hz based on a second tactile signal. Advantageously, it has been found that the occupant's hind feet are particularly receptive to vibrations in the frequency range of 20 Hz to 60 Hz, as the tactile feedback is transmitted from the hind feet through the legs to the occupant's calves and thighs, thus providing a more complete lower body massage sensation.

[0022] In one embodiment, the control system includes an input for receiving an audio signal from an audio source, and after receiving the audio signal from the audio source, the control system is configured to output a first tactile signal to actuate a first group and a second group of front tactile transducers, and to output a second tactile signal to actuate a first group and a second group of rear tactile transducers.

[0023] In one implementation, the control system is configured to generate a first tactile signal and a second tactile signal based on an audio signal. Advantageously, the first and second tactile signals generated by the control system can be complementary to the audio signal.

[0024] In one embodiment, the at least one foot tactile module includes a sealing unit. Advantageously, the sealing unit protects the at least one foot tactile module from damage caused by the ingress of fluids (water, oil, etc.).

[0025] In one embodiment, the at least one foot tactile module includes an insulating member disposed around the at least one tactile transducer. Advantageously, the insulating member helps ensure that vibrations emitted from the at least one transducer are directed toward the occupant's feet, thereby mitigating vibrations undesirably transmitted to other components of the vehicle's tactile system.

[0026] In one embodiment, the at least one foot tactile module includes a vibrating tactile membrane, to which the at least one tactile transducer is attached. Advantageously, the vibrating tactile membrane diffuses vibrations emitted from the at least one transducer throughout the at least one foot tactile module, enabling occupants with feet of various sizes to effectively use the vehicle's tactile system.

[0027] In one embodiment, the vehicle haptic system includes an input device for receiving input signals from vehicle occupants, wherein the control system is configured to adjust the haptic signals transmitted to the at least one haptic transducer in response to the input signals. Advantageously, occupants can adjust the haptic signals transmitted to the at least one haptic transducer according to their personal preferences.

[0028] In one embodiment, the vehicle tactile system includes an amplifier for amplifying tactile signals, wherein the control system is coupled to the at least one tactile transducer via the amplifier.

[0029] In one embodiment, the at least one tactile module of the vehicle tactile system is located below at least the surface layer of the foot pedal or floor portion. Advantageously, since the at least one tactile transducer of the vehicle tactile system is more efficient in transmitting massage sensations compared to known massage systems, the vehicle tactile system can be covered by soft-pack materials or the like, and thus hidden within the foot pedal or floor portion and not visible.

[0030] In one embodiment, the vehicle's foot pedal or floor portion includes a vehicle tactile system as described herein.

[0031] In some embodiments, the vehicle includes foot pedals or floor panels as described herein.

[0042] Figure 9 This illustrates another schematic representation of a vehicle's haptic system;

[0043] Figure 10 An example control system for a vehicle haptic system is shown. Detailed Implementation

[0044] This article refers to the appendix Figures 1 to 10 A vehicle tactile system 100 according to an embodiment of the present invention is described.

[0045] likeFigure 1 As shown, the vehicle haptic system 100 is installed in the vehicle 1000. The vehicle 1000 in this embodiment is an automobile, such as a wheeled vehicle, but it should be understood that the vehicle haptic system 100 can be used in other types of vehicles.

[0046] Reference Figure 2 The vehicle 1000 includes a floor portion 105 for supporting the feet 205a, 205b of an occupant 2000. The back, hips, and legs of the occupant 2000 can be supported by a vehicle seat (not shown) of the vehicle 1000. The occupant 2000 can be the driver or a passenger of the vehicle 1000. The floor portion 105 can be tilted at an angle or substantially flat.

[0047] exist Figure 2 While it is obvious that there is only one floor portion 105, the vehicle 1000 may include multiple floor portions 105, such as two, three, or more. In particular, the vehicle 1000 may include a floor portion 105 for each occupant 2000 of the vehicle 1000. The floor portion 105 may be located in the footrest space of the vehicle 1000.

[0048] The base plate portion 105 can have any suitable construction. For example, the base plate portion 105 may include an underlying frame or support member. The base plate portion 105 may include a surface layer 110. When the occupant 2000 is present, the feet 205a, 205b of the occupant 2000 typically come into direct contact with the surface layer 110. The surface layer 110 may be made of a polymer such as polyester or another low-density material. The surface layer 110 may have a thickness of approximately 10 mm.

[0049] The vehicle haptic system 100 includes at least one foot haptic module 3000 for positioning in a floor portion 105. In a vehicle 1000 including a plurality of floor portions 105 for supporting feet 205a, 205b, the foot haptic module 3000 may be positioned within each floor portion 105.

[0050] like Figure 3 , Figure 4 and Figure 5 As shown, the foot haptic module 3000 has a profile or shape with a length of 335 and a width of 330. The profile of the foot haptic module 3000 may be substantially rectangular, such that the length 335 of the foot haptic module 3000 is greater than the width 330. In use, the foot haptic module 3000 is positioned in the base plate portion 105a such that the length 335 of the foot haptic module 3000 extends laterally to the forward viewing direction of the user of the vehicle haptic system 100. The forward direction of the user of the vehicle haptic system can be understood as the forward direction of the vehicle 1000's movement.

[0051] In the example shown, the foot tactile module 3000 is located below the surface layer 110 of the base plate portion 105. Advantageously, positioning the foot tactile module 3000 below the surface layer 110 of the base plate portion 105 protects the foot tactile module 3000 from damage, such as impact damage or water ingress.

[0052] Reference Figure 3 , Figure 4 and Figure 5 The foot haptic module 3000 includes at least one haptic transducer 320. The haptic transducer 320 may include, for example, a vibrator or rocker, configured to receive haptic signals and generate vibrations based on the haptic signals. As used herein, the haptic signal is a signal generated for the purpose of actuating the haptic transducer. The haptic transducer 320 is configured to generate vibrations at low or low frequencies, typically in the range of 20 Hz to 200 Hz. The vibrations generated by the haptic transducer in response to the haptic signals may be referred to as haptic vibrations or tactile vibrations.

[0053] As will be further explained below, the vehicle haptic system 100 is configured to provide tactile or tactile feedback to the user through vibrations generated by the haptic transducer 320.

[0054] Using at least one haptic transducer 320 to provide tactile or sensory feedback to the user's feet, instead of other vibration methods such as inflatable airbag systems, ensures that the vehicle haptic system 100 is compact. The resulting system is compact enough to be positioned within the vehicle's footwell. Surprisingly, the use of haptic transducers is more effective at providing a massaging sensation through a typical vehicle floor compared to known inflatable airbag systems. Again, this allows the system to be positioned within the vehicle's footwell.

[0055] In the example shown, the foot haptic module 3000 includes a plurality of haptic transducers 320. Each of the plurality of haptic transducers 320 is offset relative to the other haptic transducers 320 along a length 335 and / or width 330 of the outline of the foot haptic module 3000. In this way, haptic feedback can be provided to different locations, such as a location corresponding to the user's foot or different locations on each of the user's feet.

[0056] Multiple tactile transducers 320 include at least two sets of tactile transducers. For example... Figure 3 As shown, at least two sets of tactile transducers 320 include a first set of tactile transducers 320a and a second set of tactile transducers 320b. Figure 3 , Figure 4 and Figure 5In the example shown, each of the first group 320a and the second group 320b includes two tactile transducers 320. However, in other examples, the first group 320a and the second group 320b may include one, three or more tactile transducers.

[0057] The tactile transducers 320 of the first group 320a are positioned to vibrate or provide a targeted vibration to the first foot of the user of the vehicle tactile system 100 when the system is in use. Similarly, the tactile transducers 320 of the second group 320b are positioned to vibrate or provide a targeted vibration to the second foot of the user of the vehicle tactile system 100. The tactile transducers 320 of the first group 320a are offset relative to the tactile transducers of the second group 320b along the length 335 of the foot tactile module 3000. That is, as Figure 5 As shown, when a user is seated in a vehicle seat adjacent to the floor portion 105 in a typical seating position, the user's first foot 205a engages the floor portion 105 at a position substantially covering or adjacent to the tactile transducers of the first group 320a. The user's second foot 205b engages the floor portion 105 at a position substantially covering or adjacent to the tactile transducers of the second group 320b. The tactile transducers 320 of the first group 320a may be offset by 200 mm to 300 mm relative to the tactile transducers 320 of the second group 320b along the length 335 of the foot tactile module 3000.

[0058] like Figure 4 As shown, the first group 320a and the second group 320b each include a front tactile transducer 325a. The first group 320a and the second group 320b also each include a rear tactile transducer 325b. The front tactile transducers 325a of the first group 320a and the second group 320b are positioned close to the forefoot of the user of the vehicle tactile system 100. The rear tactile transducers 325b of the first group 320a and the second group 320b are positioned close to the rearfoot of the user of the vehicle tactile system 100.

[0059] In other words, such as Figure 5As shown, when a user is seated in a vehicle seat adjacent to the floor portion 105 in a typical seating position, the forefoot area of ​​each of the user's feet 205a, 205b engages the floor portion 105 at a position substantially covering or adjacent to the forefoot tactile transducer 325a. The hindfoot area of ​​each foot 205b engages the floor portion 105 at a position substantially covering or adjacent to the rearfoot tactile transducer 325b. The forefoot tactile transducers 325a and 325b of each of the first group 320a and the second group 320b are offset along the width 330 of the foot tactile module. The forefoot tactile transducers 325a and 325b of each of the first group 320a and the second group 320b may be offset by 100 mm to 200 mm along the width 330 of the foot tactile module.

[0060] As used herein, the forefoot region of a user refers to the part of the foot including the phalanges and metatarsals, the ball of the foot, and the portion of the sole beneath these. As used herein, the hindfoot of a user refers to the part of the foot including the heel and ankle, and the portion of the sole beneath these. It should be understood that the forefoot region of a user is separated from the midfoot region, which includes the arch of the foot.

[0061] Positioning the tactile transducers 325a and 325b in this manner is advantageous because the forefoot and hindfoot regions are particularly sensitive to vibration, where these regions provide maximum contact between the foot and the underlying surface.

[0062] The vehicle haptic system 100 is arranged such that the front haptic transducers 325a of the first group 320a and the second group 320b are configured or arranged to receive a first haptic signal and generate vibrations based on the first haptic signal. The rear haptic transducers 325b of the first group 320a and the second group 320b are configured or arranged to receive a second haptic signal different from the first haptic signal and generate vibrations based on the second haptic signal. The first haptic signal and the second haptic signal can be distinguished by channel, frequency, amplitude, rhythm, or any other audio characteristic known in the art.

[0063] By providing different tactile signals to the forward tactile transducer 325a and the rear tactile transducer 325b, the forefoot and hindfoot regions can be activated differently. That is, a tactile signal can be sent to the forward tactile transducer 325a, causing the forefoot region of each foot to vibrate at a frequency, amplitude, or rhythm to which it is particularly sensitive. Similarly, the hindfoot region can vibrate at a frequency, amplitude, or rhythm to which it is particularly sensitive. For example, the first tactile signal can produce a vibration with a waveform that is significantly sharper or more transient than the second signal. The first tactile signal can include frequencies in the range of 60 Hz to 200 Hz, appropriately, in the range of 60 Hz to 150 Hz. The second tactile signal can include frequencies in the range of 20 Hz to 60 Hz. When applied to the hindfoot region, lower frequencies in the range of 20 Hz to 60 Hz are particularly effective because the resulting tactile feedback is more easily transmitted through the leg to the calf and thigh regions, providing a more complete tactile sensation of the lower body.

[0064] Reference Figure 2 , Figure 6 and Figure 7 The foot tactile module 3000 can be formed as a sealed unit. That is, the foot tactile module 3000 may include a sealed housing 305. The housing 305 houses the tactile transducer 320 and other additional components, such as those described below. The housing 305, any openings or connections thereof, may be sealed by waterproof seals, screws, or other sealing methods known in the art. Advantageously, the sealed unit protects the tactile transducer 320 from damage, such as water ingress or impact damage.

[0065] The foot tactile module 3000 includes a diffuser plate, such as a vibrating tactile membrane 315. A tactile transducer 320 is attached to the vibrating tactile membrane 315. That is, the tactile transducer 320 is in direct contact with the vibrating tactile membrane 315. The vibrating tactile membrane 315 covers the tactile transducers 320. The vibrating tactile membrane 315 extends beyond each of the tactile transducers 320 to provide a means for diffusing vibrations emitted from the tactile transducers 320 over the base plate portion 105 and further to the user's surface.

[0066] The foot tactile module 3000 includes an upper portion of the feet 205a and 205b facing the user during use, and a lower portion of the feet 205a and 205b facing away from the user during use. A vibrating tactile diaphragm 315 is positioned substantially facing the upper part of the foot tactile module 3000, with a tactile transducer 320 attached to the back side of the vibrating tactile diaphragm 315, i.e., the lower side facing the foot tactile module 3000. The vibrating tactile diaphragm 315 is then attached to the foot tactile module 3000 by adhesive tape, screws, or other fastening components. The vibrating tactile diaphragm 315 can be made of a polymer material such as polyurethane (PU) foam. The polyurethane (PU) foam can be high-density (approximately 320 kgm³). -3 Closed-cell polyurethane (PU) foam. Vibration-sensitive membrane 315 can have a thickness of approximately 3 mm.

[0067] Advantageously, the vibrations generated by the haptic transducer 320 are diffused throughout the floor portion 315 to ensure that the vehicle haptic system 100 is suitable for occupants 2000 of different body sizes. That is, the forefoot 210a and hindfoot 210b areas of the user's feet 205a, 205b can still be activated even if the haptic transducer 320 is not precisely aligned with these areas 205a, 205b. Additionally, the vibrating haptic membrane 315 is used to diffuse (to a certain extent) the localized vibrations felt in areas 205a, 205b to provide the user with a more uniform sensation.

[0068] The foot tactile module 3000 includes one or more insulating members 310 disposed around at least one of the tactile transducers 320. The insulating members 310 may be disposed around substantially all surfaces of the tactile transducers 320, except for the upper surface facing the foot tactile module 3000. The insulating members 310 may include an insulating layer covering the underside of each tactile transducer 320. In this example, separate insulating layers are included for the tactile transducers of the first group 320a and the second group 320b.

[0069] The insulating member 310 may include a recess for receiving each tactile transducer 320. The insulating member 310 may be made of a polymeric material such as polyurethane (PU) foam or any insulating material known in the art. Preferably, the polyurethane (PU) foam is low-density (about 49 kgm³). -3 The insulating member 310 is a closed-cell polyurethane (PU) foam. When in contact with one of the tactile transducers 320, the thickness of the insulating member 310 is at least 10 mm, and when not in contact with one of the tactile transducers 320, the thickness of the insulating member 310 is 5 mm. The insulating member 310 can be attached to the vibrating tactile membrane 315 by adhesive tape, screws, or other means known in the art.

[0070] Advantageously, when in use, the insulating member 310 can prevent vibration loss by directing vibrations emitted from the tactile transducer 320 toward the user's feet 205a, 205b. This improves efficiency and prevents damage to other components that may not be suitable for receiving such vibrations.

[0071] Figure 8 An example implementation of the vehicle haptic system 100 described above is shown. In this example, the vehicle haptic system 100 includes a control system 510. The control system 510 may be located near the center console, dashboard, media player, or navigation system of the vehicle 1000. Alternatively, the control system 510 may be located within the foot haptic module 3000.

[0072] The control system 510 is directly or indirectly coupled to the tactile transducer 320. The control system 510 may be directly or indirectly coupled to the tactile transducer 320 via any of the above-described or known in the art. The control system 510 is configured to transmit or output a tactile signal 410 to the tactile transducer 320 to actuate the tactile transducer 320 to generate vibration 425. More specifically, the control system 510 is configured to transmit a first tactile signal 410a to the front tactile transducers 325a of the first group 320a and the second group 320b, and to transmit a second tactile signal 410b to the tactile transducers 325b of the first group 320a and the second group 320b. Therefore, the control system 510 is configured to independently control the front tactile transducers 325a of the first group 320a and the rear tactile transducers 325b of the first group 320a and the second group 320b via the first tactile signal 410a and the second tactile signal 410b, respectively. Furthermore, the control system 510 can be configured to transmit individual tactile signals to each front tactile transducer 325a, and can be configured to transmit individual tactile signals to each rear tactile transducer 325b. For example, separate left and right channels of the first or second tactile signal can be sent to the tactile transducers in the first group 320a and the second group 320b, respectively.

[0073] The first tactile signal 410a and the second tactile signal 410b may be stored in the memory (e.g., internal storage device, external storage device) of the control system 510. Alternatively, the first tactile signal 410a and the second tactile signal 410b may be streamed to the control system 510 from an external source (e.g., cloud storage) via an Internet connection or other devices known in the art.

[0074] Figure 9 Another example implementation of the vehicle haptic system 100 described above is shown.

[0075] and Figure 8 Compared to the implementation method, Figure 9The vehicle haptic system 100 also includes an audio source 525. The control system 510 is coupled directly or indirectly to the audio source 525 via a wired connection, a wireless connection, or any means known in the art. The audio source 525 can be an internal source within the vehicle 1000 (e.g., a radio system) or an external source (e.g., an MP3 player or a mobile phone). The audio source 525 generates an audio signal 405 suitable for reception by the control system 510. The audio signal 405 can include, for example, an audio channel of music tracks, podcasts, or visual media (e.g., movies, television programs). The audio signal 405 can be stored in or generated from the memory of the audio source 525, for example, as a streaming signal.

[0076] Figure 9 The vehicle haptic system 100 also includes at least one audio speaker 505 for converting the audio signal 405 into sound waves 415. The at least one audio speaker 505 may include a loudspeaker, headphones, earphones, or other types of audio speakers known in the art. For example, the audio speaker 505 may be located within a door panel or a vehicle seat. In the case where at least one audio speaker 505 includes headphones or earphones, the control system 510 may be configured to detect different types of headphones or earphones and adjust any latency in the audio signal 405 accordingly.

[0077] The control system 510 is coupled to at least one audio speaker 505. The control system 510 can be coupled directly or indirectly to at least one audio speaker 505 via any means described above or known in the art. The control system 510 can be coupled to at least one audio speaker 505 via an audio amplifier for amplifying the audio signal 405. After receiving the audio signal 405 from the audio source 525, the control system 510 is configured to instruct at least one audio speaker 505 to convert the audio signal 405 into sound waves 415 so that the sound waves 415 are audible to one or more occupants 2000 of the vehicle 1000. In the case where the audio speaker 505 is, for example, a headset, the sound waves 415 may be audible to only one occupant 2000 of the vehicle 1000. Advantageously, the occupant 2000 may be able to listen to the audio signal 405 privately. In contrast, in the case where the audio speaker 505 is, for example, a loudspeaker, the sound waves may be audible to more than one occupant 2000 of the vehicle 1000.

[0078] Advantageously, the vibrations 425 emitted from the tactile transducers 325a, 325b can be complementary to the sound waves 415 emitted from at least one audio speaker 505. That is, the tactile signals (multiples) 410 can be based on the audio signal 405 in terms of frequency, amplitude, rhythm, or any other audio characteristics known in the art. In this way, the complementary tactile sensation enhances the entertainment value of listening to the audio signal 405 using the vehicle tactile system 100. For example, the complementary tactile sensation emphasizes the bass frequencies of the audio signal 405, thus satisfying occupants 2000 who require a superior audio experience with enhanced bass response while avoiding disturbing other occupants of the vehicle, as well as those with hearing impairments. This reduces the required specifications for the at least one audio speaker 505 regarding bass output. The control system 510 can be configured to generate the tactile signals (multiples) 410 based on the audio signal 405 received from the audio source 525. That is, the control system 510 can receive the audio signal 405 and can use one or more processors implementing computer-readable instructions to generate corresponding tactile signals 410.

[0079] The vehicle haptic system 100 also includes an input device 520 for receiving an input signal 420 from an occupant 2000 of at least one vehicle seat. The input device 520 may include a user interface adapted for the occupant 2000 to input instructions, such that the instructions form the input signal 420. The control system 510 is configured to adjust a first haptic signal 410a and / or a second haptic signal 410b in response to the input signal 420. The frequency, amplitude, rhythm, or any other audio characteristics known in the art of the first haptic signal 410a and / or the second haptic signal 410b may be adjusted. The first haptic signal 410a and / or the second haptic signal 410b may be paused, mute, or stopped. The control system 510 is also configured to adjust an audio signal 405 in response to the input signal 420. The frequency, amplitude, rhythm, or any other audio characteristics known in the art of the audio signal 405 may be adjusted. The audio signal 405 may be paused, mute, or stopped. The user interface of input device 520 can alert vehicle occupants 2000 that adjustments have been made to tactile signal 410 and / or audio signal 405. Control system 510 can also store instructions in memory on how to adjust tactile signal 410 and / or audio signal 405 for each vehicle seat, such that adjustments to tactile signal 410 and / or audio signal 405 are retained between ignition cycles of vehicle 1000. Upon first use of vehicle tactile system 100, tactile signal 410 and / or audio signal 405 can be adjusted to predetermined factory settings for any given frequency, amplitude, rhythm, or any other audio characteristic known in the art.

[0080] Advantageously, the tactile signal 410 and / or the audio signal 405 can be adjusted to suit the preferences of at least one occupant 2000 of a vehicle seat. The first tactile signal 410a and / or the second tactile signal 410b and / or the audio signal 405 can be adjusted such that the corresponding waveform characteristics of the first tactile signal 410a and / or the second tactile signal 410b and / or the audio signal 405 are adjusted together. For example, the rhythm of the first tactile signal 410a and / or the second tactile signal 410b and / or the audio signal 405 is adjusted. Alternatively, the first tactile signal 410a and / or the second tactile signal 410b and the audio signal 405 can be adjusted such that only one of the waveform characteristics of the first tactile signal 410a and / or the second tactile signal 410b and / or the audio signal 405 is adjusted. For example, only the intensity of the first tactile signal 410a is adjusted.

[0081] The vehicle haptic system 100 also includes an amplifier 340 for amplifying the haptic signal 410. The control system 510 is coupled to the haptic transducers 325a, 325b via the amplifier 340 through any of the above-described or known in the art means. The amplifier 340 may be located in the foot haptic module 3000, or in another location within the vehicle 1000, such as in the center console of the vehicle 1000. Advantageously, the amplifier 340 may be positioned between the first group 320a and the second group 320b (e.g., ...). Figure 7 (as shown), so as to make use of unused space in other ways and avoid the need for an external amplifier for the foot haptic module 3000.

[0082] Advantageously, the tactile signal 410 is amplified such that the tactile signal 410 is suitable for reception by the tactile transducers of the first group 320a and the second group 320b.

[0083] exist Figure 9In the diagram, system 100 is shown having a first foot tactile module 3000a and a second foot tactile module 3000b. The tactile signals sent to each foot tactile module 3000a, 3000b can be different. Similarly, the tactile signals 410 sent to each foot tactile module 3000a, 3000b can be independently controlled by the respective user. Alternatively, the tactile signals 410 sent to each foot tactile module 3000a, 3000b can be controlled only by the user of the first tactile module 3000a. Therefore, users of the first foot tactile module 3000a and the second foot tactile module 3000b can receive different vibrations 425. The vehicle tactile system 100 can be configured to disable the foot tactile modules 3000a, 3000b, such that the tactile transducer 320 is prevented from generating vibrations 425. In other embodiments, the vehicle tactile system 100 may also be configured to correspond the tactile signal 410 sent to the second foot tactile module 3000b with the tactile signal 410 sent to the first foot tactile module 3000a.

[0084] In addition, Figure 9 In the example shown, at least one audio speaker 505 includes a first audio speaker 505a and a second audio speaker 505b. The first audio speaker 505a corresponds to a first foot haptic module 3000a, and the second audio speaker 505b corresponds to a second foot haptic module 3000b. Therefore, the user of the first foot haptic module 3000a (e.g., an occupant of a first vehicle seat) and the user of the second haptic module 3000b (e.g., an occupant of a second vehicle seat) can advantageously listen to sound waves generated from individual audio signals 405a, 405b. The individual audio signal 405a can be generated by a single audio source 525 or by a first audio source and another audio source (e.g., an external source (e.g., an MP3 player)).

[0085] In cases where the audio signal 405 includes a spoken word track (e.g., an audiobook, a podcast) rather than a music track (e.g., a song), the control system 510 is configured to detect that the audio signal 405 includes a spoken word track and adjust the tactile signal 410 accordingly. The frequency, amplitude, rhythm, or any other audio characteristics known in the art can be adjusted for the first tactile signal 410a and / or the second tactile signal 410b.

[0086] If the control system 510 detects a fault in the vehicle's haptic system 100, the control system 315 is configured to instruct the haptic transducer 320 to prevent the generation of vibration 425. The fault may include, but is not limited to, a loss of connection to the audio source 525, or the detection of damage to the haptic transducer 320.

[0087] In the event that an occupant 2000 in at least one vehicle seat receives a telephone call, the control system 510 is configured to detect the telephone call and instruct the tactile transducer 320 to stop generating vibration 425. When the telephone call ends, the control system 510 is also configured to instruct the tactile transducer 320 to resume generating vibration 425.

[0088] Vehicle 1000 may include a "low power" mode, wherein, when activated, the vehicle haptic system 100 is disabled. When disabled, the haptic transducer 320 of the vehicle haptic system 100 is prevented from generating vibration 425. Similarly, vehicle 1000 may include an "economy power" mode, wherein, when activated, the vehicle haptic system 100 is adjusted. When adjusted, the frequency, amplitude, rhythm, or any other audio characteristics known in the art of the first haptic signal 410a and / or the second haptic signal 410b can be adjusted to conserve power to vehicle 1000.

[0089] Vehicle 1000 may include leg rests for supporting the lower legs of occupants 2000 in one or more vehicle seats. The leg rests have a retracted position and an extended position. In the retracted position, the occupant's legs are either not supported by the leg rest or supported by the leg rest while still engaged with the vehicle floor. In the extended position, the occupant's legs are supported by the leg rest in an elevated position. That is, the occupant's legs can extend from the vehicle floor and be raised. When the leg rests are in the extended position, the vehicle tactile system 100 is configured to disable the tactile transducer 320, thereby preventing the tactile transducer 320 from generating vibrations 425.

Processing device 5102 may be one or more electronic processing devices 5102 capable of executing computer-readable instructions. Memory device 5103 may be one or more memory devices 5103. Memory device 5103 is electrically coupled to processing device 5102. Memory device 5103 is configured to store instructions. Memory device 5103 may also store one or more audio signals, tactile signals, or means for generating tactile signals based on or corresponding to audio signals in the manner described above. Processing device 5102 is configured to access memory device 5103 and execute instructions stored on memory device 5103.

[0091] The controller 5101 includes an input device 5104 and an output device 5105. The input device 5104 may include an electrical input 5104 of the controller 5101. The output device 5105 may include an electrical output 5105 of the controller 5101. The input 5104 is arranged to receive either the audio signal 405 or the input signal 420 as described above. The output 5105 is arranged to output either the audio signal 405 or the tactile signal 410 as described above.

[0092] The method of controlling the vehicle haptic system 100 in any of the above-described manner can be provided by Figure 10 The control system 510 shown is used to execute this. In particular, the memory 5103 may include computer-readable instructions that, when executed by the processor 5102, perform the method according to an embodiment of the invention.

[0093] It should be understood that various changes and modifications can be made to the invention without departing from the scope of this application. For example, it should be understood that the vehicle haptic system 100 will be operable without the vibrating haptic membrane 315 and / or the insulating member 310.

[0094] It can be omitted Figure 9 Various aspects of the vehicle haptic system 100, such as input devices, amplifiers, or audio speakers.
