[0070] Specifically, as shown in Figure 1 The vehicle control method provided by the embodiment of the present disclosure mainly includes steps S101-S103.

[0071] S101, in response to receiving a mode switching instruction, control the vehicle to work in a sleep mode.

[0072] In the embodiment of the present disclosure, the sleep mode can be understood as a mode in which the vehicle enters a leisure state after parking. The leisure state is mainly used to provide a user with a leisure, entertainment, sleep, or the like. In the sleep mode, the user can not only listen to music and watch videos, but also can place a mattress inside the vehicle cabin, and the user can rest or sleep on the mattress.

[0073] In one embodiment of the present disclosure, in response to receiving a vehicle mode switching instruction, the vehicle mode is switched from a non-sleep mode to a sleep mode, and the vehicle is controlled to work in the sleep mode. The non-sleep mode can be a normal use mode, a KTV mode, or the like.

[0074] In the embodiment of the present disclosure, after the vehicle is switched from a driving state to a parking state, it is detected whether a vehicle mode switching instruction input by a user is received. The vehicle mode switching instruction can be input by the user in a clicking manner, in a voice manner, or in a gesture manner. For example, the user inputs a voice "please switch the mode to the sleep mode", and at this time, the vehicle mode switching instruction is successfully input.

[0075] In one specific embodiment, the vehicle mode switching instruction can be an instruction input by a user through a central display screen of the vehicle. Specifically, the user can call up a mode switching interface through clicking, sliding or voice, and display the interface on the central display screen, and then input the mode switching instruction through the displayed interface. After the vehicle receives the mode switching instruction, it can perform a mode switching operation accordingly.

[0076] In one possible embodiment, the vehicle mode switching instruction can also be input by the user through a specified terminal connected to the vehicle. Specifically, the vehicle and the specified terminal can be connected through Bluetooth. When the terminal receives a program starting instruction input by the user, it starts the specified application program and displays the interface of the specified application program. The specified application program can be an application program specially used for managing the vehicle. After displaying the interface of the specified application program on the terminal, the terminal can receive a vehicle mode switching instruction input by the user through the interface of the application program. Finally, the terminal can send the received vehicle mode switching instruction to the vehicle and instruct the vehicle to perform a mode switching operation according to the mode switching instruction.

[0077] In one embodiment of the present disclosure, the response to receiving the mode switching instruction includes detecting whether a vehicle seat in the vehicle cabin is in a first state, wherein the first state refers to an included angle between the seat back and the seat cushion being within a first angle range. When the vehicle seat is in the first state, the response to receiving the mode switching instruction is performed.

[0078] In the embodiment of the present disclosure, the first state refers to a state in which the seat back is laid back. The first angle range can be set according to actual conditions, and preferably, the first angle range is 160-180 degrees. As shown in FIG. 1, when the included angle between the seat cushion and the seat back is 180 degrees, i.e., the seat cushion and the seat back are on the same horizontal plane, the loudspeaker at the back of the seat can be seen to be blocked, and at this time, the mode switching instruction is received. When the included angle between the seat cushion and the seat back is not within the first angle range, i.e., the seat in the vehicle cabin is not in the first state, no operation is performed. Figure 2b Figure 2a As shown in FIG. 2, when the included angle between the seat cushion and the seat back is 90 degrees, i.e., the seat cushion and the seat back are in a vertical state, the loudspeaker at the back of the seat can be seen to be not blocked, and at this time, no operation is performed.

[0079] ​It should be noted that in the embodiments of the present disclosure, the adjustment mode of the seat inside the vehicle can be that the user adjusts through a mechanical handle, or the seat is adjusted according to the seat adjustment instruction input by the user. In the embodiments of the present disclosure, the adjustment mode is not limited specifically.

[0080] Further, the detection mode of the angle between the seat back and the seat cushion can be detection according to an angle sensor. In the embodiments of the present disclosure, the detection mode is not limited specifically.

[0081] In an embodiment of the present disclosure, the control of the vehicle to work in the sleep mode includes: adjusting the light device inside the vehicle to a preset brightness; and / or adjusting the output temperature and air volume of the vehicle air conditioner; and / or closing the setting function of the vehicle seat.

[0082] In the embodiments of the present disclosure, when the vehicle enters the sleep mode, the user wants to take a rest, and at this time, it can be necessary to adjust the brightness of the vehicle light to a preset brightness, wherein the preset brightness can be set according to actual conditions. In the embodiments of the present disclosure, the preset brightness is not limited specifically. Preferably, the brightness of the light device inside the vehicle is adjusted to be low, or the light device inside the vehicle is turned off.

[0083] In the embodiments of the present disclosure, the step of automatically adjusting the output temperature and air volume of the vehicle air conditioner includes adjusting the output temperature and air volume of the vehicle air conditioner to a preset temperature value and a preset air volume, respectively; collecting the heart rate and body surface temperature of the user in real time; and adjusting the output temperature and air volume of the vehicle air conditioner in real time according to the heart rate and body surface temperature of the user.

[0084] In the embodiments of the present disclosure, in order to remind the driver when an emergency or danger is encountered, the vehicle seat can be provided with a vibration function. When the vehicle is in the sleep mode, the vehicle is in a stationary state, and the probability of encountering an emergency is very low, and the user can not want to be disturbed when sleeping, and therefore, the vibration function of the vehicle seat is turned off to bring a more comfortable sleeping experience to the user.

[0085] S102, when the vehicle works in the sleep mode, the position of the head of the user is obtained by recognizing the collected image, wherein the collected image includes the head image of the user.

[0086] In the embodiments of the present disclosure, the image is collected by the camera inside the vehicle cabin, and the position of the head of the user is obtained by recognizing the collected image.

[0087] In the embodiments of the present disclosure, the position of the head of the user can be recognized by a pre-trained human head recognition model.

[0088] S103, query the position and the playing parameter corresponding relationship based on the user head position, and obtain a target playing parameter, wherein the target playing parameter comprises a loudspeaker identifier and a target audio parameter.

[0089] The position and the playing parameter corresponding relationship comprises: position-loudspeaker identifier-audio parameter. The loudspeaker identifier is used to indicate the loudspeaker that needs to be adjusted. Further, the position-loudspeaker identifier-audio parameter can be understood as the loudspeaker identifier of the loudspeaker that needs to be adjusted and the playing parameter of the loudspeaker that needs to be adjusted when the user head is in the position. The above corresponding relationship can be obtained by the designer after multiple tests before the vehicle is shipped.

[0090] In the embodiment of the present disclosure, the loudspeaker identifier-audio parameter obtained by querying the position-loudspeaker identifier-audio parameter corresponding relationship based on the user head position is used as the target playing parameter, that is, the loudspeaker identifier that needs to be adjusted and the audio parameter that each loudspeaker needs to be adjusted to.

[0091] S104, control the loudspeaker corresponding to the loudspeaker identifier to be adjusted from the current audio parameter to the target audio parameter, so that the audio focus of the multiple loudspeakers is in the preset range of the head position.

[0092] In an embodiment of the present disclosure, the audio parameter comprises a reverberation parameter, a delay parameter and / or a loudness parameter of the loudspeaker. Further, the playing parameter of each loudspeaker in the vehicle cabin can be adjusted, or only the parameter of one or part of the loudspeakers can be adjusted. The above preset range can be set according to the actual situation, which will not be described in detail in the embodiment of the present disclosure.

[0093] Specifically, the current audio parameter can be understood as the playing parameter corresponding to the current playing mode of the loudspeaker. For example, the target audio parameter a corresponding to the loudspeaker identifier 1, and the current audio parameter b of the loudspeaker corresponding to the loudspeaker identifier 1, so as to control the audio parameter of the loudspeaker identifier 1 to be adjusted from the current audio parameter b to the target audio parameter a.

[0094] In an embodiment of the present disclosure, controlling the target loudspeaker to be adjusted from the current audio parameter to the target audio parameter comprises: controlling the target loudspeaker to be adjusted from the current reverberation parameter to the target reverberation parameter; and / or controlling the target loudspeaker to be adjusted from the current delay parameter to the target delay parameter; and / or controlling the target loudspeaker to be adjusted from the current loudness parameter to the target loudness parameter.

[0095] Specifically, if the target audio parameter includes a target reverberation parameter, the target reverberation parameter is adjusted, and if the target audio parameter does not include the target reverberation parameter, the reverberation parameter can not be adjusted. That is, which parameters are included in the target audio parameter, that is, the parameters corresponding to the loudspeaker can be adjusted.

[0096] The vehicle control method provided in the embodiments of the present disclosure includes: in response to receiving a mode switching instruction, controlling the vehicle to work in a sleep mode; when the vehicle works in the sleep mode, obtaining a user head position by identifying a collected image, wherein the collected image includes a head image of the user; querying the user head position in a position and playing parameter correspondence relationship to obtain a target playing parameter, wherein the target playing parameter includes a loudspeaker identifier and a target audio parameter; and controlling a loudspeaker corresponding to the loudspeaker identifier to be adjusted from a current audio parameter to the target audio parameter, so that audio focus points of multiple loudspeakers are within a preset range of the head position. The embodiments of the present disclosure take the position of the user's head as the audio focus point in the sleep mode, adjust the audio parameter of the loudspeaker, and focus the sound near the user's head, thereby improving the listening effect of the user.

[0097] On the basis of the above-mentioned embodiments, the vehicle control method is further optimized in the embodiments of the present disclosure, and the optimized vehicle control method mainly includes the following steps:

[0098] S201, detecting whether a loudspeaker at a set position in the vehicle cabin is blocked.

[0099] In the embodiments of the present disclosure, the loudspeaker at the set position refers to a loudspeaker installed at the rear side of the seat, i.e., below the seat backrest, as shown in Figure 2a In the above-mentioned embodiments, the position of the loudspeaker is installed below the seat backrest. Figure 2a As shown in the state of FIG. 6, the loudspeaker is not blocked,As shown in the state of FIG. 7, the loudspeaker is blocked. Figure 2b

[0100] In one embodiment of the present disclosure, whether the loudspeaker is blocked is determined according to the state of the seat. When the seat backrest and the seat cushion are in the first state, it is determined that the loudspeaker at the set position is blocked, and when the seat backrest and the seat cushion are not in the first state, it is determined that the loudspeaker at the set position is not blocked.

[0101] In one embodiment of the present disclosure, the detecting whether the speaker at the set position inside the vehicle cabin is blocked comprises: during the speaker playing audio, collecting the audio played by the speaker by an audio collection device to obtain collected audio; analyzing and processing the collected audio to obtain collected audio parameters corresponding to the collected audio; and determining that the speaker inside the vehicle cabin is blocked when the collected audio parameters satisfy an audio blocking condition.

[0102] The collected audio parameters can include any one or more of output impedance, audio harmonic frequency, output power, etc., and the audio blocking condition refers to a range of audio parameters collected when the speaker is blocked.

[0103] In the embodiment of the present disclosure, the collected audio is analyzed and processed to obtain audio parameters, and it is determined whether the audio parameters are within an audio parameter range. If the collected audio is within the audio parameter range, it is determined that the collected audio parameters satisfy the audio blocking condition. If the collected audio is not within the audio parameter range, it is determined that the collected audio parameters do not satisfy the audio blocking condition.

[0104] In one specific embodiment, if the audio parameter is audio impedance, when the collected audio impedance is greater than a preset audio impedance, it is determined that the speaker is blocked. When the collected audio impedance is less than the preset impedance, it is determined that the speaker is not blocked.

[0105] S202, when the speaker is blocked, in response to receiving a mode switching instruction, controlling the vehicle to work in a sleep mode.

[0106] S203, when the vehicle works in the sleep mode, obtaining a user head position by identifying a collected image, wherein the collected image includes a head image of the user.

[0107] In the embodiment of the present disclosure, steps S202-S203 are the same as the specific manners of steps S101-S102 in the above-described embodiments, and can be described in the above-described embodiments. The present embodiment will not be described again.

[0108] S204, querying the target playing parameters based on the user head position in a position and playing parameter correspondence relationship, wherein the target playing parameters include a speaker identifier and a target audio parameter.

[0109] In the embodiment of the present disclosure, steps S202-S204 are the same as the specific manners of steps S101-S103 in the above-described embodiments, and can be described in the above-described embodiments. The present embodiment will not be described again.

[0110] S205. For the blocked speaker, turn off the blocked speaker; for one or more unblocked speakers, adjust the current audio parameters of the unblocked speakers to the target audio parameters, so that the audio focus of the unblocked speakers is within a preset range of the head position.

[0111] In this embodiment of the disclosure, since the sound heard by the user may be distorted when the speaker is blocked, in order to avoid the user hearing distorted sound and affecting the user experience, the blocked speaker can be turned off and only the parameters of the unblocked speaker can be adjusted.

[0112] In this embodiment of the disclosure, the audio parameters of the unobstructed speaker are adjusted from the current audio parameters to the target audio parameters. For example, if the unobstructed speaker is speaker 1, and the target audio parameters for speaker 1 are the target reverberation parameter and the target delay parameter, then the speaker's reverberation parameter is adjusted from the current reverberation parameter to the target reverberation parameter, and the speaker's delay parameter is adjusted from the current delay parameter to the target delay parameter.

[0113] In this embodiment of the disclosure, the sleep mode is determined by whether the speaker at the set position is blocked. After entering the sleep mode, the target playback parameters are determined according to the user's head position and the preset correspondence. The audio parameters of the speaker are adjusted from the current audio parameters to the target audio parameters so that the speaker's focus can be focused near the user's head, thereby improving the user's listening experience.
