Description

TECHNICAL FIELD

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

[0002] It is well known that occupants of a vehicle like to listen to music during a journey. In order to combat feelings of tiredness or fatigue and to stimulate the brain, the driver often plays music through a car stereo system. The stereo system in a car is usually embedded within a panel of the vehicle (for example in a door panel) to effectively propagate sound within the vehicle. The music played can cause a feeling of excitement or relaxation, depending on the type, rhythm, etc. of the music.

[0003] Research has shown that sound vibrations emitted, for example, from a stereo loudspeaker can be used for a type of therapy known as vibrational acoustic therapy (VAT). Vibrational acoustic therapy is generally defined as a therapy that uses low frequency vibrations (any frequency in the range of 20 Hz to 200 Hz) to stimulate a patient to produce a massaging effect, and thereby increase general blood circulation. Particular frequencies within this range can be used for localised areas of the body, for example the lower back or shoulders. The vibrations emitted during vibrational acoustic therapy are different to mechanical vibrations (for example, vibrations caused by driving on rough road surfaces) as mechanical vibrations cause numbness, muscle contractions and fatigue, whereas the vibrations used in vibrational acoustic therapy do not. The benefits of vibrational acoustic therapy are believed to include muscle relaxation, pain suppression, improved cognitive ability and enhanced well-being.

[0004] It is an object of the invention to improve the comfort and well-being of an occupant of a vehicle. SUMMARY

[0005] According to an aspect of the invention, there is provided a vehicle haptics system for vibrating a body part of an occupant of a vehicle, the vehicle haptics system comprising:

[0006] at least one audio loudspeaker for converting an audio signal into sound waves;

[0007] at least one haptics transducer for generating vibrations in accordance with a haptics signal;

[0008] a memory storing at least one media track, the at least one media track comprising:

[0009] at least one audio signal for driving the at least one audio loudspeaker; and

[0010] at least one haptics signal for driving the at least one haptics transducer;

[0011] a control system in communication with the at least one audio speaker and the at least one haptic transducer and configured to cause the at least one audio speaker to convert the at least one audio signal into sound waves and the at least one haptic transducer to vibrate in accordance with the at least one haptic signal.

[0012] Advantageously, providing both audio and haptic stimulation to a user of a vehicle enables the benefits of vibroacoustic therapy to be realised within a vehicle, including muscle relaxation, pain suppression, improved cognitive ability and enhanced well-being.

[0013] In embodiments, the at least one haptic signal of the at least one media track comprises at least one repeating pattern of at least one pulse.

[0014] Advantageously, it has been found that the use of at least one repeating pattern of non-static pulses within a haptic signal enables a user to be stimulated without the user being distracted. That is, the use of a repeating pattern (rather than a single, regular, repeating pulse) provides variation which avoids monotony and induces boredom. However, the use of repetition ensures that the user is not distracted. Thus, the occupant receives an improved audio and massage experience without compromising the attention or cognitive ability of the occupant.

[0015] In embodiments, the at least one haptic signal of the at least one media track comprises a first repeating pattern of at least one pulse followed by a second repeating pattern of at least one pulse.

[0016] Advantageously, it has been found that the use of multiple repeating patterns helps to ensure that the media track does not feel too repetitive or monotonous to the user. That is, the change from a first repeating pattern to another provides additional stimulation to the user which can be beneficial when the user’s interest in the first repeating pattern is waning.

[0017] In embodiments, the first repeating pattern of at least one pulse is different to the second repeating pattern of at least one pulse in at least one of:

[0018] the shape of the at least one pulse;

[0019] the frequency of the at least one pulse;

[0020] the amplitude of the at least one pulse;

[0021] the timing of the at least one pulse; and

[0022] the time between consecutive pulses.

[0023] In embodiments, the rhythm of the at least one audio signal of the at least one media track is the same as, or is associated with, the rhythm of the at least one haptic signal of the at least one media track.

[0024] Advantageously, it has been found that the similarity of the signal characteristics (e.g. rhythm, cadence, beat) of the audio and haptic signals helps to ensure that the audio and haptic stimuli work in tandem. That is, the haptic sensation complements the audio stimuli, such that the media track provides a single but multi-faceted experience to the user. This ensures that the media track does not distract the user’s attention, but rather makes them feel immersed within the track.

[0025] In embodiments, the at least one audio signal of each media track corresponds to a music track.

[0026] In embodiments, the at least one haptic signal of the at least one media track comprises a first haptic signal for driving a first haptic transducer of the at least one haptic transducer and a second haptic signal for driving a second haptic transducer of the at least one haptic transducer.

[0027] In embodiments, the first haptic signal comprises a frequency range of 60 Hz to 150 Hz and the second haptic signal comprises a frequency range of 25 Hz to 70 Hz.

[0028] Advantageously, it has been found that the spine of the occupant is particularly susceptible to vibrations in the frequency range of 60 Hz to 150 Hz, thereby maximising the massage sensation. Advantageously, it has been found that the kidneys of the occupant are particularly susceptible to vibrations in the frequency range of 25 Hz to 70 Hz, thereby maximising the massage sensation.

[0029] In embodiments, the first haptic signal comprises at least one repetition pattern of at least one pulse and wherein the second haptic signal comprises at least one repetition pattern of at least one pulse, wherein at a corresponding time for each of the first haptic signal and the second haptic signal, the at least one repetition pattern of at least one pulse of the first haptic signal differs from the at least one repetition pattern of at least one pulse of the second haptic signal in at least one of:

[0030] a shape of the at least one pulse;

[0031] a frequency of the at least one pulse;

[0032] an amplitude of the at least one pulse;

[0033] a timing of the at least one pulse; and

[0034] The interval between successive pulses.

[0040] The user physiological parameter is informed to the control system or the user, so that the track or the features of a specific track can be selected based on the needs of the user.

[0041] In an embodiment, the vehicle haptics system comprises at least one of a lighting system and a fragrance system, wherein each media track comprises at least one actuation signal, and wherein the control system is configured to actuate the at least one of the lighting system and the fragrance system in accordance with the at least one actuation signal of each media track.

[0043] Advantageously, a library of tracks is provided to the user, each track can elicit a different physiological response through the generated stimuli. Thus, the user can choose to change or enhance their state or mood.

[0044] In embodiments, a first media track of the plurality of media tracks comprises a first tempo, and a second media track of the plurality of media tracks comprises a second tempo.

[0045] Advantageously, tracks with a faster tempo can be used to invigorate the user, while tracks with a slower tempo can be used to relax the user. In this sense, the mood of the user can be changed or enhanced in accordance with the selected track.

[0046] In embodiments, upon receiving an input signal from the input device, the control system is configured to adjust the at least one audio signal and / or the at least one haptic signal. Advantageously, this allows the user to adjust the output of the media track to suit personal preferences.

[0077] Figure 12 An example control system for a vehicle haptic system is shown. Detailed Implementation

[0078] A vehicle tactile system according to an embodiment of the present invention is described herein with reference to the accompanying drawings.

[0079] First go to Figure 1 The image illustrates a vehicle haptic system 100. The vehicle haptic system 100 includes at least one audio speaker 310 for converting an audio signal 405 into sound waves 415. The at least one audio speaker 310 may include a megaphone, headphones, earphones, or other types of audio speakers known in the art. For example, the audio speaker 310 may be disposed within a door panel or within a vehicle seat. When disposed within a vehicle seat, the audio speaker 310 may be fixed to a mounting frame. Figure 1 In one example, at least one audio speaker includes a single audio speaker 310. However, in other examples, any number of audio speakers may be present within the vehicle haptic system 10, such as two, three, or more audio speakers.

[0080] The vehicle tactile system 100 includes at least one tactile transducer for generating vibrations based on tactile signals. Figure 1 In one example, at least one tactile transducer includes two tactile transducers 305a, 305b. However, in other examples, any number of tactile transducers may be present, such as one, three, or more. The tactile transducers 305a, 305b may include, for example, vibrators or rockers configured to generate vibrations in response to a tactile signal. Multiple tactile transducers 305a, 305b are configured to generate low-frequency or bass-frequency vibrations, typically in the range of 20 Hz to 200 Hz. The vibrations generated by the tactile transducers 305a, 305b in response to a tactile signal may also be referred to as tactile vibrations or haptic vibrations. As will be further explained below, the vehicle tactile system 100 is configured such that the vibrations generated by the multiple tactile transducers 305a, 305b provide tactile feedback or haptic feedback to the occupant 2000.

[0081] The vehicle haptic system 100 includes a control system 315 and a memory 316 storing at least one media track 317.

[0082] exist Figure 1 In one example, the memory 316 is separate from or outside the control system 315, such as an external storage device or a cloud storage device. In such an example, the control system 315 communicates with the memory 316. Communication can be via an Internet connection or a physical wired connection. In other examples, the memory 316 can be an internal storage device within the control system 315, such as... Figure 12 As shown in the example.

[0083] Referring to a single media track 317, media track 317 includes at least one audio signal 405 for driving audio speaker 310. Audio signal 405 may include, for example, a music track. A music track may include any number of musical instruments and musical elements, such as one or more synthesizers, bass, drums, percussion instruments, natural or everyday sounds, etc.

[0084] Media track 317 also includes tactile signals 410a, 410b for driving each tactile transducer 305a, 305b. As used herein, the tactile signals are signals generated for the purpose of actuating the tactile transducers (tactile transducers 305a, 305b in this example).

[0085] The control system 315 communicates with the audio speaker 310 and the tactile transducers 305a and 305b. This communication can be a physical or wireless coupling, either directly or indirectly, in any manner known in the art.

[0086] The control system 315 is configured to cause the audio speaker 310 to convert the audio signal 405 into sound waves 415, for example, so that one or more occupants of the vehicle can hear it. The control system 315 is also configured to cause haptic transducers 305a, 305b to vibrate in response to haptic signals 410a, 410b. The control system 315 may be located near the center console, dashboard, media player, or navigation system of the vehicle 1000. Alternatively, the control system 315 may be located within at least one vehicle seat 105. The control system 315 may be directly or indirectly coupled to the audio speaker 310 and the haptic transducers 305a, 305b in any manner known in the art.

[0087] In use, for example, in response to input from a user of the vehicle's haptic system 100 to play media track 317, the control system 315 retrieves the media track from the memory 316 and sends an audio signal 405 to the audio speaker 310, and haptic signals 410a and 410b to the haptic transducers 305a and 305b. The audio speaker 310 converts the audio signal 405 into sound waves 415, while the haptic transducers 305a and 305b convert the haptic signals 410a and 410b into vibrations. That is, the signals are played together to output the media track as a whole at a given time (i.e., all signals of the media track are output).

[0088] Advantageously, providing users of the vehicle's tactile system with both audio and tactile stimulation allows for the realization of the benefits of vibroacoustic therapy within the vehicle, including improved cognitive function and enhanced health. Improved cognitive function is particularly beneficial for the vehicle's driver.

[0089] In some embodiments, the tactile signals 410a, 410b of the media track 317 include at least one repetitive pattern of at least one pulse. That is, the tactile signals 410a, 410b may include a repetitive pattern of varying signal amplitude, which causes the corresponding tactile transducers 305a, 305b to output a repetitive pattern of vibration. By way of example, Figure 2 Six example tactile signals (i) to (vi) are shown, each tactile signal including at least one repeating pattern of at least one pulse.

[0090] The repetition pattern can include any number or type of pulses. For example, Figure 2 (i) shows a pattern 411 consisting of regularly repeating pulses. Figure 2 (iv) and Figure 2 (v) also illustrates a pattern involving regularly repeating pulses. In such examples, the envelope or shape of a single pulse is non-static. That is, the initiation, decay, sustaining, and release of the pulse are chosen to provide variation within the pulse itself.

[0091] In other examples, the repetition pattern may include two pulses with different amplitudes and / or frequencies or shapes, such as Figure 2 (ii) and Figure 2 (iii) Variations in pulse shape, amplitude, frequency, or interval may exist within the repetitive pattern of the pulse. For example, Figure 2 The tactile signal in (i) clearly shows a repetitive pattern of pulses with a slow onset, significant sustaining, and slow release amplitude envelope, while Figure 2 The tactile signals in (iv) clearly show a repetitive pattern that essentially appears to be a percussion instrument (rapid start and medium-long release). At least one pulse within the repetitive pattern can be non-static.

[0092] Advantageously, it has been found that using a repetitive pattern of at least one non-static pulse within the tactile signal can stimulate the user without causing distraction. That is, using a repetitive pattern with varying amplitudes, frequencies, and timings (rather than a single static pulse repeated at regular intervals) provides variation that avoids monotony. However, the repetitive use ensures that the user is not distracted. Therefore, the occupant receives an improved audio and massage experience without impairing their attention or cognitive abilities.

[0093] The pulse pattern can be repeated throughout the entire duration of the media track. However, for some haptic signals, the haptic signal may include a first repeating pattern of pulses, followed by a second repeating pattern of pulses, and optionally a third, fourth, or fifth repeating pattern of pulses. For example, Figure 2 The tactile signal (vi) comprises three distinct segments 412, 413, and 414, each segment including a repeating pattern of pulses. That is, the tactile signal (vi) includes: segment 412 containing a first repeating pattern, followed by another segment 413 and segment 414, each of which includes a different repeating pattern.

[0094] Each repetition pattern of a pulse may differ from other repetition patterns of a pulse, or at least may differ from previous and subsequent pulse patterns in at least one aspect of the pulse’s frequency content and shape, pulse amplitude, pulse timing, and time between pulses.

[0095] Advantageously, it has been found that using multiple repetition patterns helps ensure that media tracks do not feel too repetitive or monotonous to the user. In other words, the change from one repetition pattern to another provides the user with additional stimulation, which can be beneficial when the user's interest in the first repetition pattern diminishes.

[0096] In some embodiments, the tactile signals 410a, 410b and the audio signal 405 are configured such that the vibrations 425 emitted from the tactile transducers 305a, 305b are complementary to the sound waves 415 emitted from the audio speaker 310. For example, the rhythm of the audio signal 405 of the media track 317 may be the same as, or associated with, the rhythm of the tactile signals 410a, 410b of the media track 317. For example, for an audio signal having a fast tempo, i.e., having a beat per minute equal to or greater than 120 bpm, the rhythm of the tactile signals 410a, 410b may also have a tempo of 120 bpm. As used herein, the “tempo” of an audio or tactile signal refers to the speed at which the signal is played through the audio speaker 310 or the tactile transducers 305a, 305b. For example, at least one of the frequency content and shape of the pulses in each tactile signal, the timing of the pulses, and the time between pulses may have been selected, such that the rhythm of the tactile signals 410a, 410b matches the rhythm of the audio signal 405.

[0097] Alternatively or otherwise, the rhythm or beat of the audio signal 405 of media track 317 may be the same as, or associated with, the rhythm or beat of the tactile signals 410a, 410b of media track 317. As used herein, the “rhythm” of an audio or tactile signal refers to the temporal rhythmic pattern of the signal when played through the audio speaker 310 and the tactile transducers 305a, 305b. Similarly, the “beat” of an audio or tactile signal refers to the general sense of rhythm when the signal is played through the audio speaker 310 and the tactile transducers 305a, 305b. It will be understood that “rhythm,” “beat,” and “rhythm” are closely related terms.

[0098] For example, at least one of the frequency content and shape of the pulses, the amplitude of the pulses, the timing of the pulses, and the time between pulses in each tactile signal can be selected such that the pattern or general rhythm of the tactile signals 410a and 410b matches or is consistent with the pattern or general rhythm of the audio signal 405. As an example, at least a portion of the tactile signals 410a and 410b can be in sync with the audio signal 405. As an example, at least a portion of the tactile signals 410a and 410b can be temporally synchronized with the audio signal 405. As an example, for at least a portion of the tactile signals 410a and 410b, a relative change in pulse frequency and / or amplitude and / or interval can correspond to (i.e., occur simultaneously with) a relative change in pulse frequency and / or amplitude and / or interval of the audio signal 405.

[0099] Advantageously, it has been found that the similarity of the signal characteristics (e.g., rhythm, tempo, beat) providing audio and tactile signals helps ensure that audio and tactile stimuli work synergistically. That is, tactile sensation complements audio stimuli, allowing the media track to provide the user with a single yet multifaceted experience. This ensures that the media track does not distract the user but rather makes them feel immersed in it.

[0100] It will be understood that tactile signals 410a and 410b can be identical. For example, Figure 11 A set of four tactile signals is shown, each used to drive a separate tactile transducer. Each signal is largely identical. However, in other examples (such as those described below)... Figure 9 and Figure 10 In the example shown, each tactile transducer can be driven by a different tactile signal.

[0101] In some embodiments, the vehicle haptic system 100 includes an input device 325 for receiving input from a user of the vehicle haptic system 100. The input device 325 may include a user interface suitable for an occupant 2000 to input instructions, such that the instructions form input. The input device 325 communicates with a control system 315. Upon receiving input from a user of the vehicle haptic system 100, the input device 325 is configured to send an input signal 420 to the control system 315.

[0102] In some implementations, upon receiving an input signal 420 from the input device 325, the control system 315 is configured to adjust the audio signal 405 and / or the haptic signals 410a, 410b. Advantageously, this allows the user to adjust the output of the media track to suit personal preferences.

[0103] For example, one or both of the tactile signals 410a and 410b can be adjusted in amplitude or intensity. Furthermore, one or both of the tactile signals 410a and 410b can be paused, weakened, or stopped. Similarly, the audio signal 405 can be adjusted in amplitude or intensity. Furthermore, the audio signal 405 can be paused, weakened, or stopped. The tactile signals 410a and 410b and the audio signal 405 can be adjusted together. The memory 316 can also store instructions on how to adjust the tactile signals 410a and 410b and / or the audio signal 405, such that adjustments made to the tactile signals 410a and 410b and / or the audio signal 405 are retained between ignition cycles of the vehicle 1000.

[0104] In some embodiments, a plurality of media tracks 317 are stored in memory 316, each of the plurality of media tracks 317 including an audio signal 405 for driving an audio speaker 310 and tactile signals 410a, 410b for driving tactile transducers 305a, 305b.

[0105] When the input signal 420 received from the input device 325 relates to the selection of a media track among a plurality of media tracks, the control system 315 is configured to retrieve the selected media track from the memory 316.

[0106] In response, the control system 315 then causes the audio speaker 310 to convert the audio signal of the selected media track into sound waves, and causes the tactile transducers 305a, 305b to vibrate according to the tactile signal of the selected media track.

[0107] In other words, memory 316 stores a library of media tracks from which a user can select a specific media track. Each media track 317 can have different characteristics. For example, each media track 317 can have a different tempo. For instance, the first track can have a tempo of approximately 60 bpm to 65 bpm, the second track can have a tempo of approximately 85 bpm to 100 bpm, and the third track can have a tempo of approximately 120 bpm to 140 bpm. Other characteristics of the tracks can also vary from track to track.

[0108] Therefore, a library of tracks is provided to users, each capable of evoking different physiological and cognitive responses to the stimuli it produces. For example, a faster-paced track can be used to excite the user, while a slower-paced track can be used to relax them. In this sense, the user's emotions can be altered or amplified based on the selected track.

[0109] Figure 3 A vehicle haptic system 100 installed in a vehicle 1000 is shown. In this example, the vehicle haptic system 100 includes at least one vehicle seat 105. Two vehicle seats 105a and 105b are located in... Figure 3 It is obvious that the vehicle haptic system 100 may include any number of vehicle seats 105, such as one, two, three or more vehicle seats 105. The vehicle 1000 in this embodiment is an automobile, such as a wheeled vehicle, but it will be understood that the vehicle haptic system 100 may be used for other types of vehicles.

[0110] Reference Figure 4 and Figure 5 The vehicle seat 105 includes a backrest portion 110 for supporting an occupant 2000 (and more specifically, for supporting the back of the occupant 2000). The occupant 2000 may be the driver of the vehicle 1000 or a passenger of the vehicle 1000. The vehicle seat 105 includes a base portion 120 for further supporting the buttocks and legs of the occupant 2000. The base portion 120 engages with the backrest portion 110 at an angle of approximately 90 degrees; however, this angle may be configured by the occupant 2000.

[0111] Reference Figure 5 , Figure 6 and Figure 7 The tactile transducers 305a and 305b are disposed on the backrest portion 110 of the vehicle seat 105 or inside the backrest portion 110 of the vehicle seat 105.

[0112] In this example, at least one tactile transducer includes at least two sets of tactile transducers, namely, a first set of at least one tactile transducer 305a and a second set of at least one tactile transducer 305b. In the illustrated example, each of the first and second sets includes two tactile transducers. However, in other examples, the first set of tactile transducers 305a and the second set of tactile transducers 305b may include one, three, or more tactile transducers.

[0113] The backrest portion 110 includes a central longitudinal axis 115 that divides or equally divides the backrest portion 110 into two substantially equal longitudinal segments, namely a first segment and a second segment. The first segment can be laterally offset from the central longitudinal axis 115 in a first direction, and the second segment can be laterally offset from the central longitudinal axis 115 in a second direction opposite to the first direction.

[0114] The first group of tactile transducers 305a is disposed along the central longitudinal axis 115 of the backrest 110. The tactile transducers 305a can be disposed at any position along the central longitudinal axis 115 of the backrest portion 110. For example, the first group may include a first tactile transducer 305a disposed in the upper section of the backrest portion 110 and a second tactile transducer 305a disposed in the lower section of the backrest portion 110, wherein both tactile transducers 305a are disposed along the central longitudinal axis 115. Suitably, the first tactile transducers 305a and the second tactile transducers 305a of the first group may be longitudinally offset along the central longitudinal axis 115 of the backrest portion 110 by a distance ranging from 100 mm to 200 mm, suitably from 120 mm to 140 mm.

[0115] like Figure 4As shown, when occupant 2000 is seated in vehicle seat 105, the central longitudinal axis 115 of the backrest portion 110 is aligned with the spinal region 205 of occupant 2000. As used herein, the spinal region 205 of occupant 2000 refers to the region located along the central longitudinal axis of the back of occupant 2000. Therefore, when actuated, the first set of tactile transducers 305a is positioned to vibrate at least the spinal region 205 of occupant 2000 in use. In doing so, the vibrations emitted by the first set of tactile transducers 305a provide tactile feedback or a massage sensation to the spinal region 205 of occupant 2000. Positioning the tactile transducers 305a in this manner is advantageous because the spinal region 205 of occupant 2000 is particularly sensitive to vibration. Therefore, the perception of low frequencies emitted by the first set of tactile transducers 305a by occupant 2000 is maximized.

[0116] The second group of tactile transducers 305b are each disposed at a position laterally offset relative to the central longitudinal axis 115 of the backrest portion 110. As used herein, the lateral offset position of the central longitudinal axis 115 of the backrest portion 110 refers to a position offset in a direction substantially to the left or right of the central longitudinal axis 115. That is, as described above, the second group of tactile transducers 305b is positioned in either the first or second segment of the backrest portion 110. In the illustrated example, the second group of tactile transducers 305b is disposed on either side (i.e., the left and right) of the central longitudinal axis 115. That is, the second group includes a first tactile transducer 305b laterally offset relative to the central longitudinal axis 115 of the backrest portion 110 in a first direction, and a second tactile transducer 305b laterally offset relative to the central longitudinal axis 115 of the backrest portion in a second direction opposite to the first direction. The second group of tactile transducers 305b are positioned at the same height along the central longitudinal axis 115 of the backrest portion 110, such that the tactile transducers 305b are mirror images of each other when viewed relative to the central longitudinal axis 115 of the backrest portion 110. Furthermore, the second group of tactile transducers 305b can be positioned at equidistant distances from the central longitudinal axis 115 in both a first and a second direction. Suitablely, the first and second tactile transducers 305b of the second group can be laterally offset from the central longitudinal axis 115 of the backrest portion 110 in both the first and second directions by a distance ranging from 80 mm to 100 mm. The backrest portion 110 also includes a base 125 and a lateral axis 130. The base 125 of the backrest portion 110 is located at the intersection of the backrest portion 110 and the base portion 120. A transverse axis 130 bisects the backrest portion 110, dividing it into a substantially upper and lower section. In this example, a second set of tactile transducers 305b is positioned between the base 125 of the backrest portion 110 and the transverse axis 130 bisecting the backrest portion 110, i.e., in the lower section of the backrest portion 110. Using this position, at least one tactile transducer 305b of the second set is positioned to vibrate the kidney region 210 of an occupant 2000 of at least one vehicle seat 105 during use. That is, when the occupant 2000 is seated in at least one vehicle seat 105, the second set of tactile transducers 305b is generally aligned with or adjacent to the corresponding kidney region 210 of the occupant 2000 of at least one vehicle seat 105. As used herein, the kidney region 210 of the occupant 2000 refers to the region located in the lower back region of the occupant 2000, more specifically, the side of the lower back region. Thus, the second set of tactile transducers 305b is positioned to vibrate the kidney region 210 of at least one occupant 2000 of a vehicle seat 105 during use.The vibrations emitted by the second set of tactile transducers 305b are configured to provide tactile feedback or a massage sensation to the kidney region 210 of the occupant 2000. Positioning the tactile transducers 305b in this manner is advantageous because the kidney region 210 of the occupant 2000 is particularly sensitive to vibrations. This maximizes the occupant 2000's perception of the low-frequency frequencies emitted by the second set of tactile transducers 305b.

[0117] Suitablely, the second set of tactile transducers 305b can be disposed at a distance ranging from 20 mm to 40 mm above the base 125 of the backrest portion 110. Furthermore, suitablely, the first set of second tactile transducers 305a can be disposed at a distance ranging from 100 mm to 140 mm above the base 125 of the backrest portion 110.

[0118] Figure 5 , Figure 6 and Figure 7 An example assembly is shown, including a backrest portion 110, a first set of tactile sensors 305a, and a second set of tactile sensors 305b. Figure 6 The frame structure of the backrest portion 110 is shown in the diagram. The backrest portion 110 includes a mounting frame 340 positioned within the frame structure of the backrest portion 110. A first set of tactile transducers 305a and a second set of tactile transducers 305b are mounted on the mounting frame 340. The tactile transducers 305a and 305b can be mounted on the mounting frame 340 in any suitable manner. In this example, the mounting frame 340 includes recesses for receiving each tactile transducer 305a and 305b. Other components of the vehicle tactile system 100 described herein, such as an amplifier 320 or an audio speaker 310, may also be mounted to the mounting frame 340. The mounting frame 340 can be securely attached to the frame structure of the backrest portion 110 by screws or other fasteners. Advantageously, the mounting frame 340 provides a single attachment point to the backrest portion 110 for multiple components (e.g., the first set of haptic transducers 305a and the second set of haptic transducers 305b), thereby improving the efficiency of assembling the vehicle haptic system 100.

[0119] In this example, the control system 315 is configured to independently control the first group of tactile transducers 305a and the second group of tactile transducers 305b. That is, a separate signal can be sent to each group of transducers. Furthermore, the control system 315 can be configured to deliver individual tactile signals to the tactile transducers within each group.

[0120] As described above, each media track 317 may include a first tactile signal 410a for driving a first tactile transducer 305a and a second tactile signal 410b for driving a second tactile transducer 305b. In this example, the first tactile signal 410a is used to drive the first group of tactile transducers 305a, and the second tactile signal 410b is used to drive the second group of tactile transducers 305b.

[0121] In some implementations, each media track may include a separate tactile signal for each tactile transducer in each of the first and second groups. Advantageously, emitting different vibrations from the tactile transducers within each group can provide the occupants 2000 with a more immediate experience.

[0122] By providing different tactile signals to each of the first and second sets of tactile transducers, the spinal region 205 and the kidney region 210 can be activated differently by the tactile transducers. That is, a tactile signal can be sent to the first set of tactile transducers 305a, causing the spinal region 205 to vibrate at a frequency, amplitude, or rhythm to which the spinal region 205 is particularly sensitive. Similarly, the kidney region 210 can be vibrated at a frequency, amplitude, or rhythm to which the kidney region 210 is particularly sensitive. For example, the first tactile signal can produce a vibration with a waveform that is substantially sharper or more transient than the second signal. The first tactile signal can include frequencies in the range of 60 Hz to 200 Hz, suitably in the range of 60 Hz to 150 Hz. The second tactile signal can include frequencies in the range of 20 Hz to 70 Hz (suitably 25 Hz to 70 Hz).

[0123] Advantageously, at least one vehicle seat 105 can transmit vibrations generated by the second set of tactile transducers 305b from the backrest portion 110 to the base portion 120. Thus, in addition to the kidney region 210 of the occupant 2000 in at least one vehicle seat 105, at least one tactile transducer 305b of the second set vibrates the buttocks and legs of the occupant 2000 during use. Therefore, the vehicle tactile system 100 thus does not require additional tactile transducers to vibrate the buttocks and legs of the occupant 2000. Advantageously, frequencies to which the kidney region 210 is particularly sensitive can also be transmitted to the base portion 120.

[0124] The backrest portion 110 of the vehicle seat 105 includes a dispersion plate, such as a vibrating tactile membrane 300. A first set of tactile transducers 305a and a second set of tactile transducers 305b are attached to the vibrating tactile membrane 300. That is, the first set of tactile transducers 305a and the second set of tactile transducers 305b are in direct contact with the vibrating tactile membrane 300. The vibrating tactile membrane 300 covers the first set of tactile transducers 305a and the second set of tactile transducers 305b. The vibrating tactile membrane 300 extends beyond the location of each of the tactile transducers 305a, 305b to provide a surface for propagating vibrations emitted from the tactile transducers 305a, 305b to the backrest portion 110 and further to the surface of the occupant 2000. The vehicle seat 105 includes a front surface 135 facing at least one occupant 2000 when in use, and a rear surface 140 facing away from the occupant 2000 when in use. The vibrating tactile diaphragm 300 is positioned substantially facing the front surface 135 of the vehicle seat 105, wherein a first set of tactile transducers 305a and a second set of tactile transducers 305b are fixed to the back of the vibrating tactile diaphragm 300, i.e., the rear surface 140 facing the vehicle seat 105. The vibrating tactile diaphragm 300 is then secured to the mounting frame 340 by screws or other fastening components.

[0125] The vibrating tactile membrane 300 can be made of a polymer material, such as polyurethane (PU) foam. The polyurethane (PU) foam can, for example, have a density of approximately 320 kgm³. -3 High-density closed-cell polyurethane (PU) foam. The vibration-sensitive membrane 300 can have a thickness of approximately 3 mm.

[0126] Advantageously, the vibrations generated by the tactile transducers 305a and 305b are transmitted to the backrest portion 110, ensuring that the vehicle tactile system 100 is suitable for occupants 2000 of different body sizes. That is, even if the transducers 305a and 305b are not precisely aligned with the spinal region 205 and the kidney region 210, the spinal region 205 and the kidney region 210 can still be activated. Additionally, the vibrating tactile membrane 300 is used to transmit (to a certain extent) the localized vibrations felt in regions 205 and 210 to provide a more uniform sensation to the occupant 2000.

[0127] At least one vehicle seat 105 may include one or more insulating members disposed around at least one of the tactile transducers 305a, 305b. The insulating members may be disposed around substantially all surfaces of the tactile transducers 305a, 305b (except the surface facing the back of the occupant 2000). The insulating members may include an insulating layer covering the surface of each tactile transducer 305a, 305b facing the rear surface 140 of the vehicle seat 105. In the example, separate insulating layers are included for the first group of tactile transducers 305a and the second group of tactile transducers 305b.

[0128] Advantageously, when in use, the insulating components can prevent vibration loss by guiding vibrations emitted from the tactile transducers 305a and 305b toward the back of the occupant 2000. This improves efficiency and prevents damage to other components that may not be suitable for receiving such vibrations.

[0129] The insulating member may include a recess for receiving each tactile transducer 305a, 305b. The insulating member may be made of a polymeric material (e.g., polyurethane (PU) foam) or any insulating material known in the art. Preferably, the polyurethane (PU) foam is low-density (approximately 49 kgm³). -3 The insulating member is a closed-cell polyurethane (PU) foam. At the location in contact with one of the tactile transducers 305a and 305b, the thickness of the insulating member is at least 10 mm, and at the location not in contact with one of the tactile transducers 305a and 305b, the thickness of the insulating member is 5 mm. The insulating member can be fixed to the vibrating tactile membrane 300 by adhesive tape, screws, or other means known in the art.

[0130] The backrest portion 110 includes a material covering or padding disposed between the vibrating tactile membrane 300 and the occupant 2000, such that the first set of tactile transducers 305a and the second set of tactile transducers 305b indirectly contact the occupant 2000 through the material covering or padding.

[0131] The material covering may include cushioning material for comfort and a covering or lining providing the exterior of the backrest portion 110. The cushioning material may be foam. The foam thickness may be from 40 mm to 80 mm, suitably from 50 mm to 70 mm, and suitably from 55 mm to 60 mm. Providing foam of this thickness ensures that the haptic transducers 305a, 305b do not affect the comfort of the occupant 2000; the thickness is significantly greater than that used in conventional vehicle kits (typically between 20 mm and 25 mm). It will be understood that the foam thickness may not be uniform across the entire backrest portion 110. Instead, the foam thickness may be greater in the areas covering the haptic transducers 305a, 305b.

[0132] Figure 8 An example of a vehicle haptic system 100 implemented within a vehicle 1000 is shown. The vehicle haptic system 100 has a... Figure 1 The similarity of the vehicle tactile systems shown is illustrated, where corresponding features have the same reference numerals.

[0133] exist Figure 8 In the diagram, system 100 is shown with both a first vehicle seat 105a and a second vehicle seat 105b, each with separate hardware, i.e., each vehicle seat has haptic transducers 305a and 305b and an audio speaker 310. However, it will be noted that shared hardware may exist between vehicle seats 105a and 105b. For example, the audio speaker 310 may be shared by both vehicle seats 105a and 105b. The occupants of each vehicle seat 105a and 105b can each choose to experience different media tracks 317, for example, one using headphones as the audio speaker 310 and the other using the main vehicle audio speaker as the audio speaker 310.

[0134] Figure 8 The vehicle tactile system 100 shown also includes at least one pressure sensor 335, such as a pressure sensor 335 for each vehicle seat 105a, 105b.

[0135] At least one pressure sensor may be disposed on the backrest portion 110 and / or base portion 120 of the vehicle seat 105. The at least one pressure sensor is configured to measure the pressure applied to the vehicle seat 105 and generate a pressure signal 430. In use, the pressure applied to at least one vehicle seat 105 is generated by an occupant 2000 sitting on the base portion 120 and / or supported by the backrest portion 110.

[0136] The vehicle haptic system 100 can be configured such that haptic transducers 305a and 305b cannot be actuated or stop actuation when the pressure signal is below a lower limit. A pressure signal below the limit can instruct occupants 2000 to no longer sit on the base portion 120 or recline forward relative to the backrest portion 110, so that they will no longer benefit from the actuation of haptic transducers 305a and 305b. The lower limit can be equal to the minimum weight of an occupant 2000 expected to be seated in or supported by at least one vehicle seat 105; therefore, when there is no occupant 2000 in at least one vehicle seat 105, at least one haptic transducer 305a of the first group and at least one haptic transducer 305b of the second group are not actuated. In this way, the vehicle haptic system 100 can advantageously save power when occupants 2000 are not seated in or supported by at least one vehicle seat 105, thereby improving the efficiency of operating the vehicle haptic system 100. Additionally, the experience of other vehicle occupants 2000 can be improved by removing background "noise" from haptic transducers 305a and 305b when they are not needed.

[0137] Alternatively, the vehicle haptic system 100 may be configured such that the haptic transducers 305a, 305b cannot be actuated or are de-actuated when other sensing devices detect that the occupant 2000 is not seated on the base portion 120 and / or not supported by the backrest portion 110 of at least one vehicle seat 105. Other sensing devices may include the use of camera devices, motion sensors, or other devices known in the art.

[0138] exist Figure 8 In the example, the vehicle haptic system 100 also includes an amplifier 320 for amplifying the haptic signals 410a, 410b and the audio signal 405. It will be understood that more than one amplifier may be present, for example, an amplifier for each vehicle seat 105a, 105b and / or an amplifier for each signal of the media track.

[0139] The control system 315 is coupled to the haptic transducers 305a, 305b and the audio speaker 310 via amplifier 320 in any manner described above or known in the art. Amplifier 320 may be located on at least one vehicle seat 105, or in another location within the vehicle 1000, such as the center console of the vehicle 1000. Amplifier 320 may amplify signals from media tracks to make them suitable for reception by the corresponding haptic transducers or audio speakers.

[0140] The vehicle haptic system 100 may include at least one sensor arrangement 336 configured to measure physiological parameters relating to a user of the vehicle haptic system 100 and generate sensor signals 431. The sensor arrangement may include one or more heart rate sensors and electrodermal response sensors. Figure 8 As shown, the sensor arrangement 336 communicates with the control system 315, such that the control system 315 is configured to receive sensor signals 431 from at least one sensor arrangement 336.

[0141] In response to sensor signal 431 indicating that the user's physiological parameters of the vehicle's haptic system 100 are above an upper threshold or below a lower threshold, control system 315 can be configured to adjust the audio signal 405 and / or haptic signals 410a, 410b of the currently playing media track. For example, if the measured physiological parameters indicate that the user is drowsy (e.g., their heart rate has dropped below a threshold), control system 315 can adjust the signals to make the user more focused and alert. For example, the signal strength can be increased or the tempo can be sped up. Similarly, if the measured physiological parameters indicate that the user is anxious (e.g., their heart rate has risen above a threshold), control system 315 can adjust the signals to make the user more relaxed.

[0142] In response to sensor signal 431 indicating that the user's physiological parameters of the vehicle haptic system 100 are above an upper threshold or below a lower threshold, control system 315 is configured to retrieve another media track from a plurality of media tracks in memory. For example, if the user's physiological parameters indicate anxiety, control system 315 may be configured to select a more relaxing media track. Control system 315 may change media track 317 without user input, or control system 315 may send a notification signal to the user interface of vehicle haptic system 100 suggesting the selection of another media track from a plurality of media tracks in memory 316.

[0143] Figures 9 to 11 An example of tactile signals used in a vehicle tactile system is shown. Specifically, Figures 9 to 11 Each of the examples shows a group of four tactile signals, each tactile signal used to drive a corresponding tactile transducer, such as tactile transducers 305a in the first group and tactile transducers 305b in the second group. For Figure 9 and Figure 10The tactile signals are four distinct tactile signals. However, it will be understood that the same tactile signal can be sent to each tactile transducer in the first group, and the same tactile signal can be sent to each tactile transducer in the second group. The repetition patterns of the pulses of the different tactile signals can differ in at least one of the following aspects: the frequency components and shape of the pulses, the amplitude of the pulses, the timing of the pulses, and the frequency of the pulses (i.e., the interval between pulses).

[0144] Figure 12 An example control system is shown, such as control system 315 as described above. In this example, control system 315 includes a controller 3151, but it will be understood that this is merely illustrative. Controller 3151 includes a processing device 3152 and a memory device 3153. Processing device 3152 may be one or more electronic processing devices 3152 capable of executing computer-readable instructions. Memory device 3153 may be one or more memory devices 3153. Memory device 3153 is electrically coupled to processing device 3152. Memory device 3153 is configured to store instructions. Memory device 3153 may also store one or more media tracks including audio signals and haptic signals in the manner described above. Processing device 3152 is configured to access memory device 3153 and execute instructions stored thereon.

[0145] The controller 3151 includes an input device 3154 and an output device 3155. The input device 3154 may include an electrical input 3154 of the controller 3151. The output device 3155 may include an electrical output 3155 of the controller 3151. The input 3154 is arranged to receive any of the signals described above, such as the signal forming the media track, the input signal 420, or the pressure signal 430. The output 3155 is arranged to output any of the signals described above, such as the audio signal 405 or the tactile signal 410.

[0146] The method of controlling the vehicle haptic system 100 in any of the above-described manner can be provided by Figure 12 The control system 315 shown is used to execute this. In particular, the memory 3153 may include computer-readable instructions that, when executed by the processor 3152, perform the method according to an embodiment of the invention.

[0147] It will be understood that various changes and modifications can be made to the present invention without departing from the scope of this application. For example, it will be understood that the vehicle haptic system 100 will still be operable without the vibrating haptic membrane 300. Furthermore, [details omitted]. Figure 8 The vehicle haptic system 100 described herein includes various aspects such as input device 325, pressure sensor 335, sensor arrangement 336, amplifier 320, or vehicle seat.

[0148] In some examples, the vehicle haptic system 100 may include at least one of a lighting system and a fragrance system. Each media track may include an actuation signal for each of these systems, such that the control system is configured to actuate the lighting system or the fragrance system according to the actuation signal of each media track. Lighting and fragrance can complement the intended effect of the media track on the user. For example, soft lighting and specific fragrances can be used to enhance the relaxing effect of a slow-paced media track on the user.

[0149] In some examples, at least one tactile transducer may be located in the base portion 120 of the vehicle 105. In some examples, at least one tactile transducer may be located in or part of a foot tactile module in the foot pedal or floor portion of the vehicle.

[0150] For example, at least one tactile transducer may include a first group of at least one tactile transducer and a second group of at least one tactile transducer, the first group of at least one tactile transducer being used to vibrate a first foot of a user of the vehicle tactile system, and the second group of at least one tactile transducer being used to vibrate a second foot of the user of the vehicle tactile system. The foot tactile module may have a profile having a length and a width, wherein the first group of at least one tactile transducer is offset from the second group of at least one tactile transducer along the length and / or width of the profile of the at least one foot tactile module.

[0151] In some examples, at least one tactile transducer may include a tactile transducer in one or more of the backrest portion 110, the base portion 120, and the foot tactile module.
