For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0057] Reference below Figure 1-Figure 11 The control method of the vehicle audio according to the embodiment of the present invention is described, which can increase driving entertainment and improve driving safety.

[0058] like Figure 1-Figure 11 As shown, the vehicle audio control method according to an embodiment of the present invention includes:

[0059] A100, detecting the actual position where the user's limbs contact the steering wheel 1;

[0060] A200, detecting the contact force between the user's limbs and the steering wheel 1;

[0061] A300, obtaining image information of contact between the user's limbs and the steering wheel 1;

[0062] A400, generates target audio according to actual position, force and image information;

[0063] A500, control audio actuator 2 to play target audio.

[0064] The steering wheel 1 is a wheel-shaped device for controlling the driving direction of a car, ship, airplane, etc. The function of the steering wheel 1 is to convert the force applied by the driver to the edge of the steering wheel into torque and then transmit it to the steering shaft. It is mainly composed of a frame, foaming, and mounting buckles or screw holes corresponding to the main driver airbag DAB, etc., and the existing steering wheel 1 can be provided with a horn button, a music playback control button, etc. to meet more usage requirements.

[0065] Specifically, when driving a vehicle, the user needs to contact the steering wheel 1 with his or her limbs, such as hands, and a sensor 4 is provided on the steering wheel 1 to obtain the contact position between the user's limbs and the steering wheel 1, and the force exerted by the user's limbs on the steering wheel 1 can be detected by the sensor 4. At the same time, a camera 3 and other devices can be provided inside the vehicle to obtain image information when the user contacts the steering wheel 1, and then the corresponding target audio can be generated through the contact position information, force and contact image of the user and the steering wheel 1, and an audio actuator 2 is provided on the vehicle. The target audio generated through the contact position, force and contact image of the user and the steering wheel 1 can be played through the audio actuator 2, and the audio actuator 2 can also only play music.

[0066] Furthermore, when the user is driving, his limbs will come into contact with different positions of the steering wheel 1, thereby generating different contact position information and image information at the time of contact with the steering wheel 1, and different forces of action will be generated during the contact. Different of the above information corresponds to different target audio. Different information of the user's limbs at the steering wheel 1 can affect the audio actuator 2. Different target audio is generated according to different information of the user's contact with the steering wheel 1, so that the audio actuator 2 can play different audio accordingly. When the user contacts different positions of the steering wheel 1, the audio actuator 2 can be controlled to play different target audio, thereby increasing the entertainment during driving, avoiding driving fatigue and the like, and improving driving safety.

[0067] According to the in-vehicle audio control method of an embodiment of the present invention, the audio actuator 2 is controlled to play the target audio through the actual position of the contact between the user's limbs and the steering wheel 1, the force of action, and the image information of the contact between the user's limbs and the steering wheel 1, thereby increasing driving entertainment, ensuring driving safety, and having better use effects and a wider range of applications.

[0068] Among them, the sensor 4 arranged on the steering wheel 1 can be set as a pressure sensor 4, or can be set as an elastic wave sensor 4, etc. It should be noted that elastic wave is a kind of stress wave, which is the form of stress and strain caused by disturbance or external force in the elastic medium. There are elastic forces interacting between particles in the elastic medium, that is, after a particle leaves the equilibrium position due to disturbance or external force, the elastic restoring force causes the particle to vibrate, thereby causing displacement and vibration of surrounding particles, so the vibration propagates in the elastic medium, accompanied by energy transfer, and stress and strain will change where the vibration reaches. The elastic wave signal on the steering wheel 1 is the pressure applied by the user when contacting the steering wheel 1, and the position of the user's limbs on the steering wheel 1 and the magnitude of the force can be judged by the pressure.

[0069] In some embodiments, Figure 2 As shown, before controlling the audio actuator 2 to play the target audio, it also includes:

[0070] A600, obtain the running status of audio executor 2;

[0071] A700. After the audio actuator 2 is turned on, a target audio that matches the audio actuator 2 is generated according to the actual position, force and image information.

[0072] Specifically, the audio actuator 2 has different states, and the user can adjust the operating state of the audio actuator 2 to turn on or off the audio actuator 2. When the user is driving, his limbs will contact different positions of the steering wheel 1, thereby generating different contact positions and image information at the time of contact with the steering wheel 1, and different forces of action will be generated during the contact. Different of the above information corresponds to different target audio.

[0073] Among them, when the user turns off the audio actuator 2, the contact position information generated between the user's limbs and the steering wheel 1, the image information during contact, and the different forces generated during contact will not affect the audio actuator 2. When the user turns on the audio actuator 2, the different contact position information, image information during contact, and the different forces generated during contact between the user's limbs and the steering wheel 1 can generate different target audios, and then different target audios can be played through the audio actuator 2, so that when the user contacts different positions of the steering wheel 1, the audio actuator 2 can be controlled to play different audios, thereby increasing the entertainment during driving, avoiding driving fatigue and the like, and improving driving safety.

[0074] In some embodiments, Figure 3-Figure 4 As shown, the control method of the vehicle audio includes:

[0075] A610, get the opening status of the hollow drum;

[0076] A620, after the hollow drum is turned on, generate the target audio that matches the hollow drum;

[0077] A630, and control the hollow drum to play the target audio;

[0078] Or, A640, get the start status of the metronome;

[0079] A650, after the metronome is turned on, generates target audio that matches the metronome;

[0080] A660, and controls the metronome to play the target audio.

[0081] Specifically, the vehicle is provided with an audio actuator 2, and the user can adjust the operating state of the audio actuator 2 to turn on or off the audio actuator 2. At the same time, the audio actuator 2 includes a metronome option or a hollow drum option, that is, the user can turn the metronome on or off, and can also turn the hollow drum on or off.

[0082] Furthermore, when the hollow drum option in the audio actuator 2 is in the off state, the different position information, image information and force generated between the user and the steering wheel 1 cannot generate the target audio matching the hollow drum. When the hollow drum in the audio actuator 2 is in the on state, the different position information, image information and force generated between the user and the steering wheel 1 can generate the target audio matching the hollow drum.

[0083] When the metronome option in the audio actuator 2 is in the off state, the different position information, image information, and force generated between the user and the steering wheel 1 cannot generate a target audio that matches the metronome. When the metronome in the audio actuator 2 is in the on state, the different position information, image information, and force generated between the user and the steering wheel 1 can generate a target audio that matches the metronome.

[0084] At the same time, the metronome and the hollow drum in the audio actuator 2 can also be set to the on state. The different position information, image information and force generated between the user and the steering wheel 1 can respectively generate a target audio matching the metronome or a target audio matching the hollow drum, thereby increasing the fun. When the human brain beats the rhythm, the auditory cortex, motor cortex, subcortical basal ganglia and cerebellum areas will be activated. The metronome can train the sense of rhythm and speed, and can effectively relax the nerves and strengthen the body.

[0085] In some embodiments, Figure 5 As shown, before controlling the audio actuator 2 to play the target audio, it also includes:

[0086] A800, get the status of custom touch settings;

[0087] A900, after the custom touch settings are turned on, the target audio that matches the custom touch settings is generated based on the actual position, force, and image information.

[0088] Specifically, when driving a vehicle, the user can obtain different position information, image information, and forces generated between the user and the steering wheel 1 through devices such as the sensor 4 provided on the steering wheel 1 and the camera 3 provided inside the vehicle, and the user can set customized touch corresponding to different position information, image information, and forces, making the vehicle more convenient to use.

[0089] Furthermore, the user can set custom touch and control the activation state of custom touch, that is, the user can turn on custom touch or turn off custom touch. When the user turns off custom touch, the user will not trigger the custom touch when using the steering wheel 1. When the user turns on custom touch, the different position information, image information and force generated between the user and the steering wheel 1 can correspond to the execution of custom touch, thereby generating a target audio that matches the custom touch setting, and the target audio can be played through the audio actuator 2.

[0090] In actual use, the vehicle's central control display screen can provide a visual interface, and users can set the functions of different touch areas on the steering wheel 1. For example, tapping the central control screen in the left area of ​​the steering wheel 1 will display the left rearview mirror adjustment page, and tapping the central control screen in the right area of ​​the steering wheel 1 will display the right rearview mirror adjustment page, making operation more convenient and more interactive.

[0091] In some embodiments, before obtaining the state of the custom touch setting, the method further includes: actively inputting a custom touch action.

[0092] Specifically, when driving a vehicle, the user can obtain different position information, image information, and forces generated between the user and the steering wheel 1 through devices such as the sensor 4 provided on the steering wheel 1 and the camera 3 provided inside the vehicle, and the user can actively input customized touch actions corresponding to different position information, image information, and forces, making the vehicle more convenient to use.

[0093] Furthermore, the user can actively input customized touch actions corresponding to different position information, image information, and forces, and when the user turns on customized touch, the different position information, image information, and forces generated between the user and the steering wheel 1 can correspond to the user's customized touch actions, that is, the user can achieve customized touch through different touch methods and touch frequencies such as tapping, squeezing, and patting, and then generate target audio that matches the customized touch settings, and the target audio can be played through the audio actuator 2.

[0094] In some embodiments, generating target audio according to the actual position, force and image information includes: when it is determined that the number of times the user continuously and forcefully slaps the steering wheel 1 is within a first set range based on the actual position, force and image information, generating and playing soothing persuasive words.

[0095] Specifically, when the user is driving a vehicle, different position information, image information, force information, etc. will be generated between the user and the steering wheel 1, and the above information can reflect the user's emotional state at this time. The user can use the palm or fingers to slap or tap on different positions of the steering wheel 1 in sequence or simultaneously to generate different position information, image information, force information, etc., and when the number of times the user slaps or taps the steering wheel 1 per unit time is greater than the set value, it can be determined that the user is continuously and forcefully slapping the steering wheel 1.

[0096] Furthermore, a first range can be set according to the number of times the user slaps or knocks the steering wheel 1 in a unit time. When the number of times the user continuously and forcefully slaps the steering wheel 1 is within the first range, the audio actuator 2 can play soothing advice, such as "If you feel irritated, try taking a deep breath", etc., thereby soothing the user's emotions and improving driving safety.

[0097] In some embodiments, the method for controlling the in-vehicle audio further includes: when it is determined based on the actual position, force and image information that the number of times the user continuously and forcefully slaps the steering wheel 1 is within a second set range, generating persuasive words to remind the user to be alert to road rage and pay attention to safety, as well as music to ease emotions; wherein the number of times within the second set range is greater than the number within the first set range.

[0098] Specifically, based on the different position information, image information, force information and other information generated by the user at the steering wheel 1, it is determined that when the user continuously and vigorously hits the steering wheel 1, the audio actuator 2 plays a prompt sound, and the difference in the above information makes the prompt sound played by the audio actuator 2 also different.

[0099] Furthermore, a second range can be set according to the number of times the user slaps or knocks the steering wheel 1 in a unit time, and the number of times in the second range is greater than the number in the first range. When the number of times the user continuously and forcefully slaps the steering wheel 1 is within the second range, the audio actuator 2 plays a warning message to remind the user to be alert to road rage and pay attention to safety, and the audio actuator 2 simultaneously plays soothing music, thereby soothing the user's emotions and improving driving safety. The number of times within the first set range is, for example, 2 times, 3 times, etc., and the number of times within the second set range is, for example, 4 times, 5 times, etc.

[0100] In some embodiments, Figure 6As shown, generating target audio according to actual position, force and image information includes:

[0101] A410, obtaining the actual frequency and actual time of the user's contact with the steering wheel 1 according to the image information;

[0102] A420, and jointly generates target audio according to the actual position, force, actual frequency and actual time.

[0103] Specifically, when the user is driving the vehicle, the sensor 4 can be used to detect the force of the user's limbs on the steering wheel 1. At the same time, a camera 3 and other equipment can be set inside the vehicle to obtain image information when the user contacts the steering wheel 1. The image information can reflect the contact frequency and contact time of the user when contacting the steering wheel 1, and then the corresponding target audio can be generated through the actual position information, force, actual frequency and actual time of the user's contact with the steering wheel 1. An audio actuator 2 is provided on the vehicle. The target audio generated by the contact position, force and contact image of the user and the steering wheel 1 can be played through the audio actuator 2, and the audio actuator 2 can also only play music.

[0104] Furthermore, when the user is driving, his limbs will come into contact with different positions of the steering wheel 1, thereby generating different contact position information and image information of the contact with the steering wheel 1. The image information can reflect the contact frequency and contact time of the user when contacting the steering wheel 1, and different forces will be generated when contacting. Different of the above information corresponds to different target audio. Different information of the user's limbs at the steering wheel 1 can affect the audio actuator 2. Different target audio is generated according to different information of the user's contact with the steering wheel 1, so that the audio actuator 2 can play different audio accordingly. When the user contacts different positions of the steering wheel 1, the audio actuator 2 can be controlled to play different target audio, thereby increasing the entertainment during driving, avoiding driving fatigue and the like, and improving driving safety.

[0105] The invention also provides a vehicle-mounted audio control device.

[0106] The in-vehicle audio control device according to the embodiment of the present invention is applicable to any of the in-vehicle audio control methods described above, and includes: a detection module, an analysis module and a control module.

[0107] Specifically, the detection module is provided with a sensor 4, a camera 3, etc. The detection module can detect the actual position where the user's limbs contact the steering wheel 1, detect the force of contact between the user's limbs and the steering wheel 1, and obtain image information of contact between the user's limbs and the steering wheel 1, etc. The analysis module is used to generate target audio according to the actual position, force and image information, and the control module is used to control the audio actuator 2 to play the target audio.

[0108] According to the control device of the vehicle audio of the embodiment of the present invention, the audio actuator 2 is controlled to play the target audio through the actual position of the contact between the user's limbs and the steering wheel 1, the force of action, and the image information of the contact between the user's limbs and the steering wheel 1, thereby increasing driving entertainment, ensuring driving safety, and having better use effect and a wider range of applications.

[0109] The present invention also provides a vehicle.

[0110] A vehicle according to an embodiment of the present invention is provided with the above-mentioned vehicle audio control device.

[0111] According to the vehicle of the embodiment of the present invention, the vehicle is provided with a control device for in-vehicle audio, and the control device for in-vehicle audio controls the audio actuator 2 to play the target audio through the actual position of the contact between the user's limbs and the steering wheel 1, the force of action, and the image information of the contact between the user's limbs and the steering wheel 1, thereby increasing driving entertainment, ensuring driving safety, and achieving better use effect and a wider range of applications.

[0112] Reference below Figure 8-11 As shown in the figure, a method for controlling vehicle audio according to some specific embodiments of the present invention and implementation steps of the method for controlling vehicle audio are described.

[0113] By setting the control method of the vehicle audio, there are multiple implementation modes, such as a metronome music mode, an ethereal drum music mode, a complaint venting mode and a custom mode.

[0114] like Figure 8 As shown, the specific steps of the metronome music mode are: the detection module is provided with a sensor 4, a camera 3, etc., and the detection module detects the actual position where the user's limbs contact the steering wheel 1, detects the contact force of the user's limbs and the steering wheel 1, and obtains the image information of the contact between the user's limbs and the steering wheel 1, etc. The analysis module generates a target audio matching the metronome according to the actual position, the contact force and the image information, and the control module obtains the operating status of the audio actuator 2. When the metronome in the audio actuator 2 is turned off, the audio actuator 2 only plays music. When the metronome in the audio actuator 2 is turned on, the control module controls the audio actuator 2 to play the target audio matching the metronome generated by the analysis module.

[0115] like Fig. 9As shown, the specific steps of the hollow drum music mode are: the detection module is provided with a sensor 4, a camera 3, etc., and the detection module detects the actual position where the user's limbs contact the steering wheel 1, detects the contact force of the user's limbs and the steering wheel 1, and obtains the image information of the contact between the user's limbs and the steering wheel 1, etc. The analysis module generates a target audio matching the hollow drum according to the actual position, the contact force and the image information, and the control module obtains the operating status of the audio actuator 2. When the metronome in the audio actuator 2 is turned off, the audio actuator 2 only plays music. When the metronome in the audio actuator 2 is turned on, the control module controls the audio actuator 2 to play the target audio matching the hollow drum generated by the analysis module.

[0116] like Fig.10 As shown, the specific steps of the complaining venting method are: the detection module is provided with a sensor 4, a camera 3, etc., and the detection module detects the actual position where the user's limbs contact the steering wheel 1, detects the force of the contact between the user's limbs and the steering wheel 1, and obtains image information of the contact between the user's limbs and the steering wheel 1.

[0117] When the detection module does not obtain the actual position, force and image information of the user tapping the steering wheel 1, the analysis module and the control module do not respond;

[0118] When the detection module obtains the force of the user tapping the steering wheel 1, and the analysis module analyzes that the force is less than the set value, the control module does not respond;

[0119] When the detection module obtains the force of the user tapping the steering wheel 1, and the analysis module analyzes that the force meets the set value, but the contact frequency and contact time reflected by the image information are less than the set value, the control module does not respond;

[0120] When the detection module obtains the touch force of the user tapping the steering wheel 1, and the analysis module analyzes that the touch force meets the set value, and at the same time, the contact frequency with the steering wheel 1 reflected by the image information meets two to three consecutive times, the analysis module generates soothing persuasive words, and the control module controls the audio actuator 2 to play the soothing persuasive words;

[0121] When the detection module obtains the touch force of the user tapping the steering wheel 1, and the analysis module analyzes that the action force meets the set value, and at the same time, when the contact frequency with the steering wheel 1 reflected by the image information meets the requirements of more than four consecutive times, the analysis module generates persuasive words to remind the user to be vigilant against road rage and pay attention to safety, and the control module controls the audio actuator 2 to play persuasive words to remind the user to be vigilant against road rage and pay attention to safety, as well as music to ease emotions.

[0122] like Fig.11As shown, the specific steps of the customization method are: the user actively sets the custom action by typing or handwriting, and the user touches the steering wheel 1. The sensor 4 provided on the steering wheel 1 and the camera 3 provided inside the vehicle can obtain the actual position, force and image information of the user when contacting the steering wheel 1 at this time. The analysis module analyzes the above information and then generates a target audio that matches the custom touch setting. The analysis module determines whether the trigger information meets the custom action trigger condition. If not, the control module does not respond.
