Description

Technical Field

[0001] The present invention relates to the field of vehicle control, and in particular to a method and a device for operating a vibration mechanism of a vehicle seat. Background Art

[0002] In modern vehicles, more and more vehicle seats are equipped with vibration mechanisms, which include multiple vibration elements that can be activated individually. By activating one or more vibration elements, the seat massage function is realized. At present, the seat massage function of a vehicle usually has a fixed massage or vibration mode. For example, multiple massage modes are displayed on the display and control interface of the vehicle, wherein in each massage mode, which vibration element works with which vibration intensity is pre-set. By the user of the vehicle seat selecting the desired massage mode, the corresponding vibration element is activated to provide the user with the desired massage effect.

[0003] However, for modern vehicles with increasingly higher levels of intelligence, fixed massage or vibration modes are too rigid, and the vibration mechanism cannot actively and intelligently provide massage or vibration effects, especially cannot provide massage or vibration effects that match the vehicle's interior atmosphere or vehicle driving conditions. Therefore, there is a need to expand the seat massage function of vehicles. Summary of the invention

[0004] In view of this, the present invention provides a method and apparatus for operating a vibration mechanism of a vehicle seat, which expands the seat massage function and solves at least one of the above-mentioned defects.

[0005] To achieve the above object, according to one aspect of the present invention, a method for operating a vibration mechanism of a vehicle seat is provided, wherein the vibration mechanism comprises a plurality of vibration elements that can be activated individually, and the method comprises the following steps:

[0006] Acquire a first signal, where the first signal includes an audio signal of the vehicle and / or a current driving dynamic parameter of the vehicle;

[0007] Determining a vibration pattern from the first signal, the vibration pattern characterizing which vibration element or elements are activated and the respective vibration intensities of the activated vibration elements;

[0008] determining a control signal for controlling the vibration mechanism based at least on the vibration pattern;

[0009] Output a drive control signal to the vibration mechanism.

[0010] The vibration mechanism of the vehicle seat is arranged in the seating part and / or the backrest part of the vehicle seat and is used to realize the seat massage function. The vibration mechanism can be a mechanical massage mechanism or a pneumatic massage mechanism, but is not limited to these two implementation modes. As long as the vibration mechanism includes multiple vibration elements that can be activated separately, it can be applicable to the present invention.

[0011] The vibration pattern shows which vibration element or elements are activated, i.e. in which areas of the vehicle seat vibrations are generated to provide a massage or vibration effect. The vibration pattern also shows the respective vibration intensities of the activated vibration elements. Preferably, the respective vibration intensities of the activated vibration elements have default values, which correspond to vibration intensities that are acceptable to most users.

[0012] “Determining the actuation signal at least based on the vibration pattern” means that for determining how to actuate the vibration mechanism, it is sufficient to use the vibration pattern determined by the first signal according to the invention, and manual input by the user of the vehicle seat is dispensable.

[0013] According to the present invention, there is no need for the user of the vehicle seat to manually determine the massage mode of the vehicle seat. The vehicle seat can (automatically) provide a massage or vibration effect that matches the interior atmosphere of the vehicle or the driving status of the vehicle, which brings a completely new riding experience to the user.

[0014] In a preferred embodiment, the vibration pattern is determined by the frequency spectrum of the vehicle's audio signal. The audio signal is, for example, music played by the vehicle's audio system, which includes multiple frequency bands, each of which corresponds to a vibration element in an area of ​​the vehicle seat. The vibration intensity of the vibration element in each area is, for example, proportional to the sound intensity of the audio signal in that frequency band, and the vehicle seat will vibrate with the music. This provides the user with a full range of visual, auditory, tactile, and other senses, especially a tactile sense that is compatible with the music.

[0015] The above-mentioned vibration pattern design method is only exemplary, and those skilled in the art can conceive of equal or unequal frequency band division methods and other functional relationships between vibration intensity and sound intensity.

[0016] In a preferred embodiment, the first signal is a sound signal input by a microphone of the vehicle. For example, when the driver and / or the front passenger sings using the microphone of the vehicle, the vehicle seat will vibrate along with the singer's singing. Thus, the vehicle seat provides a tactile karaoke effect and enriches the entertainment needs of the user.

[0017] Alternatively, the first signal is a sound signal output by a speaker of the vehicle. For example, when the driver and / or the front passenger listens to music using a car radio or a car audio player, the vehicle seat provides a tactile sensation along with the melody or rhythm of the music.

[0018] In a preferred embodiment, it is provided that the control signal is output only after a predeterminable time period has expired after the determination of the control signal. This means that the synchronization between the control of the microphone and the vibration element is achieved by an adjustable delay. As a result, the effect of the tactile karaoke can be flexibly adjusted, making it lively and interesting for the user of the vehicle seat.

[0019] In a preferred embodiment, the first signal is at least one of the following parameters: vehicle speed, vehicle acceleration and engine speed. The driving dynamics parameter characterizes the driving state of the vehicle, such as acceleration, deceleration, turning, etc. The vehicle seat generates vibrations that match the driving state of the vehicle. As a result, a tactile sensation related to the vehicle dynamics is generated, thereby bringing a new driving / riding experience to the user of the vehicle seat.

[0020] In a preferred embodiment, it is provided that which vibration element or elements are activated depends on the direction of the vehicle acceleration. For example, when the vehicle accelerates, the vibration element of the backrest part is activated, when the vehicle brakes, the vibration element of the seat part is activated, and when the vehicle turns, the vibration element on the left or right side is activated. This creates a tactile sensation that matches the vehicle dynamics.

[0021] In a preferred embodiment, it is provided that the respective vibration intensity of the activated vibration elements depends on the value of the first signal, i.e. at least one of the values ​​of the vehicle acceleration, the engine speed and the vehicle speed. For example, when the vehicle accelerates suddenly, in addition to the push-back feeling, the vehicle seat will also give the driver an additional large vibration effect. The engine speed can also be taken into account, because during the acceleration phase of the vehicle, a higher engine speed often corresponds to a higher longitudinal acceleration. The vehicle speed can also be taken into account, i.e., different vibration effects are given to the driver depending on the vehicle speed, in particular, it can avoid the driver's speed perception deviation in the case of long-term cruise control (e.g. highway driving). As a result, a tactile experience that matches the vehicle dynamics is generated.

[0022] In a preferred embodiment, it is provided that the vibration pattern is determined only when the value of the first signal exceeds the starting threshold. For example, the starting threshold is related to the value of the vehicle acceleration. The vibration effect of the vehicle seat usually gives the user a feeling of tension and excitement, which is usually associated with intense driving and is unnecessary when driving at a constant speed or smoothly with a lower acceleration. Those skilled in the art can appropriately select the starting threshold so that the timing of introducing the tactile sensation of the vehicle seat is adapted to the current vehicle type. The starting threshold can also be related to the value of the engine speed and the value of the vehicle speed. As a result, a tactile sensation that matches the vehicle dynamics is generated.

[0023] In a preferred embodiment, the method further comprises the steps of:

[0024] acquiring a second signal, the second signal being predeterminable by a user of the vehicle seat;

[0025] determining an adjustment factor from the second signal, the adjustment factor being used to adjust the respective vibration intensity of the activated vibration elements;

[0026] Therein, a control signal for controlling the vibration mechanism is determined based on the vibration pattern and the adjustment factor.

[0027] The second signal corresponds to the manual setting of the vibration intensity by the user of the vehicle seat. The second signal is, for example, the setting of the equalizer of the vehicle audio system, thereby changing the vibration intensity of the vibration element in the corresponding area by changing the sound intensity of a certain frequency band of the audio signal. The second signal is, for example, the setting of the vehicle's driving mode (such as urban roads, highways, racetracks, off-road venues, etc.), thereby changing the vibration intensity of the vibration element by changing the intensity of driving. For example, urban roads correspond to low intensity, while racetracks correspond to high intensity. In this way, the vibration intensity of the vibration element can be set in an individualized manner.

[0028] According to one aspect of the present invention, there is provided a device for operating a vibration mechanism of a vehicle seat, the vibration mechanism comprising a plurality of individually activatable vibration elements, characterized in that the device comprises:

[0029] First input module: The first input module is used to obtain a first signal, the first signal including an audio signal of the vehicle and / or a current driving dynamic parameter of the vehicle;

[0031] Output module: The output module is used to output drive control signals to the vibration mechanism.

[0032] In a preferred embodiment, it is provided that the first input module comprises A 2 B bus interface and / or LIN / CAN bus interface. 2 The B-bus interface can acquire audio signals and the current driving dynamics parameters of the vehicle can be acquired via the LIN / CAN bus interface.

[0033] In a preferred embodiment, the device further comprises:

[0034] Second input module: The second input module is used to obtain a second signal, and the second signal can be predetermined by a user of the vehicle seat;

[0035] The calculation module is further used to determine an adjustment coefficient from the second signal, the adjustment coefficient is used to adjust the vibration intensity of each activated vibration element, and the calculation module is further used to determine a control signal for controlling the vibration mechanism based on the vibration pattern and the adjustment coefficient.

[0036] In a preferred embodiment, it is provided that the second input module comprises a LIN / CAN bus interface. A second signal which can be predetermined by a user of the vehicle seat can be acquired via the LIN / CAN bus interface, the second signal corresponding to a manual setting of the vibration intensity by the user of the vehicle seat.

[0049] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope of the present invention. Similarly, for the sake of clarity and simplicity, the description of well-known functions and structures is omitted in the following description.

[0050] Figure 1 The vehicle seat 10 according to the present invention is shown as a single seat. The vehicle seat 10 can be a driver's seat, a front passenger seat, or an independent seat in the rear row. The vehicle seat 10 can also be a seat in a rear seat column. The vehicle seat 10 is fixed to a floor (not shown) of the vehicle in a manner that it can move forward and backward and / or left and right.

[0051] The vehicle seat 10 includes a backrest portion 11 and a seating portion 12 , which are pivotally connected.

[0052] A vibration mechanism is arranged inside the backrest part 11 and the seating part 12, and the vibration mechanism includes eight vibration elements 1~8 that can be activated individually. The installation position of the vibration element that is not visible from the outside is shown by a dotted circle in the accompanying drawings. The vibration elements 1~8 can be mechanical vibration elements, which simulate the way of manual massage by reciprocating translational motion or rotational motion through mechanical parts such as massage heads and massage wheels. The vibration elements 1~8 can also be pneumatic vibration elements, which perform massage through pneumatic parts such as air bags and air bags to simulate the way of pressing and massaging by human hands. The necessary components of the above two vibration elements are well known to those skilled in the art and do not need to be described in detail here. What is important for the present invention is that each vibration element 1~8 can be driven and controlled individually to provide vibration with a certain vibration intensity.

[0053] The vehicle seat 10 further includes a vibration mechanism control device 20, which generates a control signal for controlling the vibration mechanism and transmits the control signal to the eight vibration elements 1 to 8. The vibration mechanism control device 20 may be arranged outside the vehicle seat 10 (e.g., Figure 1 As shown), it can also be arranged in, for example, the backrest part 11 or the seating part 12.

[0054] Figure 2 It is a vibration mechanism control device 20 according to the present invention.

[0055] The vibration mechanism control device 20 includes A 2 B bus interface 21 , LIN / CAN bus interface 22 , control unit 23 and output interface 24 .

[0056] A 2 The B bus interface 21 is used to acquire audio signals and transmit them to the control unit 23. The LIN / CAN bus interface 22 is used to acquire status signals related to vehicle driving dynamics and control signals related to vehicle functions and transmit them to the control unit 23. The control unit 23 is used to evaluate the acquired signals, generate and transmit drive signals to the output interface. The drive signal is used to drive the electric motor of the vibration elements 1 to 8 for driving the air pump or mechanical components, and is preferably a pulse width modulation (PWM) signal. The drive signal includes not only information about which vibration element or elements are activated, but also information about the respective vibration intensity of the activated vibration elements, and these two pieces of information together constitute a vibration pattern. The output interface 24 is used to output the drive signal.

[0057] Figure 3 This is the first use example of the vibration mechanism control device according to the present invention. 2The B bus interface 21 is connected to microphones installed at the driver and the co-pilot of the vehicle to obtain the sound signals input from the microphones. The LIN / CAN bus interface 22 is connected to the equalizer of the vehicle audio to obtain the setting parameters of the vehicle audio. The output interface 24 is connected to the vibration elements 1 to 8 of the vehicle seat 10.

[0058] When the driver and / or the front passenger sings, the control unit 23 evaluates the sound signal. For the sound signal dominated by low frequencies, the vibration elements 7, 8 on the seat part and the vibration elements 5, 6 on the lower part of the backrest are activated; for the sound signal dominated by medium frequencies, the middle vibration elements 3, 4 on the backrest are activated; for the sound signal dominated by high frequencies, the upper vibration elements 1, 2 on the backrest are activated. The vibration intensity of the vibration element is proportional to the sound intensity, and the greater the sound intensity, the stronger the tactile sensation.

[0059] An alternative to the vibration pattern is to generate vibration only for a specific frequency band, such as a sound signal in the low frequency range, or to generate vibration only when the overlap between the spectrum shape of the singer's sound signal and a predetermined spectrum shape reaches a predefined threshold. It is also conceivable that the vibration intensity is in a square function, a logarithmic function, or other functional relationship with the sound intensity.

[0060] By means of an equalizer, the sound intensity of, for example, high frequencies, medium frequencies, and low frequencies can be set. As a result, the vibration intensity of the vibration element in the corresponding area of ​​the vehicle seat can be changed, thereby additionally influencing the vibration pattern.

[0061] The synchronization between the microphone and the actuation of the vibration element is achieved by means of an adjustable delay, which gives the driver and / or front passenger an interesting tactile karaoke effect.

[0062] Also not shown is that A 2 The B bus interface 21 can also be connected to a vehicle audio system to obtain a voice signal output from the vehicle audio system. In this case, the vehicle seat 10 will vibrate along with the music played by the vehicle audio system.

[0063] Figure 4 This is a second example of using the vibration mechanism control device according to the present invention. 2 The B-bus interface 21 is not used, and the LIN / CAN bus interface 22 is connected to a superior vehicle controller 30 to obtain current driving dynamic parameters and user-set parameters of the vehicle.

[0064] The driving dynamic parameters include at least: vehicle speed, vehicle acceleration and engine speed, which can be obtained, for example, through the CAN bus data of the vehicle. In particular, the vehicle acceleration includes the longitudinal acceleration along the longitudinal direction of the vehicle and the lateral acceleration along the lateral direction of the vehicle. Preferably, the driving dynamic parameters are acquired in real time, which means that the vibration mechanism of the vehicle seat is operated according to the current driving dynamic parameters. The user-set parameters include driving modes, such as urban roads, highways, racetracks, off-road venues, etc.

[0065] For the positive longitudinal acceleration of the vehicle, i.e., the vehicle is accelerating, the body of the user of the vehicle seat will be close to the backrest part, and all vibration elements 1 to 8 will be activated. For the negative longitudinal acceleration of the vehicle, i.e., the vehicle is braking, the user's body will slightly lean forward and leave the backrest part due to inertia, and vibration elements 7 and 8 will be activated. For the lateral acceleration of the vehicle, i.e., the vehicle is turning, the user's body will slightly leave one side of the vehicle seat, and the vibration elements 1, 3, 5, 7 or vibration elements 2, 4, 6, 8 on the other side will be activated.

[0066] Preferably, the vibration pattern is determined only when the value of the acceleration exceeds a start threshold, for example 0.2 m / s². When the vibration pattern is determined, the vibration intensity increases with the increase of the engine speed, for example linearly. When the value of the acceleration is below the start threshold, the vibration pattern is no longer determined. Alternatively, a start threshold related to the value of the vehicle speed and the value of the engine speed can be set, and the influencing factor of the vibration intensity can also be the value of the vehicle acceleration and the value of the vehicle speed.

[0067] It is also preferred that, as the value of the longitudinal acceleration increases, the following four groups of vibration elements are activated in sequence from bottom to top: vibration elements 7 and 8, vibration elements 5 and 6, vibration elements 3 and 4, and vibration elements 1 and 2. Overlapping vibration patterns are also conceivable, for example, activating vibration elements 5 and 6 in advance before deactivating vibration elements 7 and 8. The acceleration values ​​of switching different groups of vibration elements can be linear, for example, 2m / s², 4 m / s² and 6 m / s², or non-linear. Those skilled in the art can appropriately select the switching point so that the timing of introducing the tactile sensation of the vehicle seat is adapted to the acceleration performance of the current vehicle.

[0068] Similar to the first use example, the user of the vehicle seat can additionally influence the vibration pattern. This is done by obtaining the set driving mode from the vehicle controller 30 via the LIN / CAN bus interface 22: urban roads, highways, racetracks, off-road venues, etc. Different driving modes correspond to different adjustment coefficients. The adjustment coefficient is presented, for example, in the form of a percentage, indicating whether the vibration intensity in the vibration pattern should be increased or decreased. For example, low-intensity driving such as urban roads requires a calm atmosphere, and the vibration intensity should be reduced, that is, an adjustment coefficient of less than 100% should be set, while high-intensity driving such as racetracks requires a dynamic atmosphere, and the vibration intensity should be increased, that is, an adjustment coefficient of more than 100% should be set.

[0069] The first use example and the second use example can be used separately or in combination with each other. For example, when the driver is cruising at a constant speed and playing music, the vehicle seat provides a "music tactile sensation". When the driver suddenly accelerates, the vehicle seat can interrupt the "music tactile sensation" and provide an "acceleration tactile sensation" instead, or provide "music tactile sensation" and "acceleration tactile sensation" in different areas of the seat at the same time. The above combination is only exemplary, and those skilled in the art can adaptively set the combination according to the number and distribution of vibration elements.

[0070] Figure 5 Schematic diagram of the main process of the method for operating the vibration mechanism of the vehicle seat according to the present invention. The method comprises the following steps:

[0071] Step S1: Acquire a first signal, where the first signal includes an audio signal of the vehicle and / or current driving dynamic parameters of the vehicle.

[0072] Preferably, the vibration pattern is determined by the frequency spectrum of an audio signal of the vehicle. Preferably, the first signal is a sound signal input by a microphone of the vehicle. Preferably, the control signal is output only when a predeterminable time period has expired after the control signal is determined. Preferably, the first signal is at least one of the following parameters: vehicle speed, vehicle acceleration and engine speed.

[0073] Step S2: Determine a vibration pattern from the first signal, wherein the vibration pattern indicates which vibration element or elements are activated and the respective vibration intensities of the activated vibration elements.

[0074] Preferably, the vibration pattern is determined by the frequency spectrum of the audio signal of the vehicle. In addition, it is preferred that: which vibration element or elements are activated depends on the direction of the vehicle acceleration; the respective vibration intensity of the activated vibration elements depends on the value of the first signal; and the vibration pattern is determined only when the value of the first signal exceeds the activation threshold.

[0075] Step S3: Acquire a second signal, which can be predetermined by a user of the vehicle seat.

[0076] Step S4: determining an adjustment coefficient based on the second signal, wherein the adjustment coefficient is used to adjust the respective vibration intensities of the activated vibration elements.

[0077] Step S5: determining a control signal for driving the vibration mechanism based on the vibration pattern and the adjustment coefficient.

[0078] Step S6: Outputting a driving control signal to the vibration mechanism.

[0079] According to the present invention, the vibration pattern is determined in step S2, which means that the respective vibration intensity of the activated vibration elements has been predetermined. Therefore, steps S3 and S4 are optional steps and can be omitted, and then in step S5, the control signal for driving the vibration mechanism is determined only based on the vibration pattern, or the adjustment factor is set to 100% (which means that the vibration intensity is not additionally affected).

[0080] The modules involved in the embodiments of the present invention may be implemented by software or hardware. The modules described may also be set in a processor, for example, it may be described as: a processor includes a first input module, a second input module, a calculation module and an output module. The names of these modules do not constitute a limitation on the modules themselves in some cases, for example, the first / second input module may also be described as a "first / second acquisition module".

The above computer-readable medium carries one or more programs, and when the above one or more programs are executed by a device, the device: obtains a first signal, the first signal includes an audio signal of the vehicle and / or the current driving dynamic parameters of the vehicle; determines a vibration pattern from the first signal, the vibration pattern characterizes which vibration element or elements are activated and the respective vibration intensities of the activated vibration elements; determines a drive signal for driving a vibration mechanism based at least on the vibration pattern; and outputs the drive signal to the vibration mechanism.

[0082] It should be noted that the computer-readable medium shown in the present invention may be a computer-readable signal medium or a computer-readable storage medium or any combination of the above two. The computer-readable storage medium may be, for example, but not limited to, an electrical, magnetic, optical, electromagnetic, infrared, or semiconductor system, device or device, or any combination of the above.

In the present invention, a computer-readable storage medium may be any tangible medium containing or storing a program that can be used by or in combination with an instruction execution system, device or device. In the present invention, a computer-readable signal medium may include a data signal propagated in a baseband or as part of a carrier wave, which carries a computer-readable program code. This propagated data signal may take a variety of forms, including but not limited to electromagnetic signals, optical signals, or any suitable combination of the above.
