[0002] A car amplifier is an audio power amplifier in a car's audio and video system. A power amplifier, also known as a PA, selects and pre-processes the audio input signal before amplifying it, ensuring the signal has the power to drive the speakers. With the advancement of various electric vehicle technologies, high-end electric vehicles are increasingly appearing on the market, and high-power audio designs are increasingly appearing in mass-produced vehicles. However, high-power amplifier configurations, if their power consumption is not properly controlled during use, can increase the vehicle's energy loss and, to a certain extent, reduce the vehicle's range. When using the car's audio system, the power amplifier's functional modules do not need to operate at maximum power at all times.

[0051] The above and other features of the present invention will become apparent with reference to the accompanying drawings. It will be readily understood by those skilled in the art that these drawings are for illustrative purposes only and are not intended to limit the scope of protection of the present application. In addition, similar numbers in the drawings represent similar components, wherein:

[0052] FIG1 is a schematic flow chart showing a power consumption control method according to an embodiment of the present invention;

[0053] FIG2 shows a module diagram of a power consumption control system according to an embodiment of another aspect of the present invention. DETAILED DESCRIPTION

[0054] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0055] The terms "up," "down," "left," "right," "front," "back," "front," "back," "top," and "bottom" mentioned or potentially mentioned in this specification are defined relative to the configurations shown in the accompanying drawings. These are relative concepts and may vary depending on the location or usage of the device. Therefore, these or other directional terms should not be construed as restrictive. Furthermore, the terms "first," "second," "third," and similar expressions are used solely for descriptive and distinguishing purposes and should not be construed as indicating or implying the relative importance of the corresponding components or the order or sequence of their assembly.

[0056] Car audio refers to the audio system installed in a vehicle. It generally consists of six components: software and media, audio source, pre-stage signal control, power amplifier, speakers, and transmission. The power amplifier, also known as the power amplifier, connects the head unit and speakers. Its function is to select and pre-process the audio input signal, then amplify it to ensure that the electrical signal has the power to drive the speakers. A power amplifier is an essential component of a good audio system. The power amplifier included with the head unit often cannot truly amplify the sound current, so installing an additional power amplifier is essential for a good musical experience in a vehicle. Generally speaking, the power of the power amplifier should be greater than that of the speakers. A subwoofer amplifier can increase the reserve power, reduce noise interference, and minimize distortion.

[0057] Currently, many high-end electric vehicles use high-power power amplifiers to provide good sound effects, reduce noise interference, and thus improve the user experience. Many current high-power power amplifiers include functional modules such as PA chips, DSP chips, Boost chips, and A2B chips for processing and controlling various electrical and audio signals. However, for vehicles equipped with high-power power amplifiers, the power amplifier consumes a lot of energy when the audio system is in use, reducing the vehicle's range and potentially affecting the user experience. Audio equipment does not always require all functional modules of the power amplifier to operate at their maximum power. For many sound states and sound types of audio equipment, the perfect solution can be achieved by combining the operation of some functional modules. In this case, it is possible to consider appropriately reducing the power consumption of other functional modules.

[0058] Referring to Figure 1, a flowchart of a power consumption control method according to one embodiment of the present invention is shown. The power consumption control method controls the power consumption of a power amplifier by matching the sound state of the speaker with an appropriate power consumption atomization control type, and includes the following steps:

[0059] Acquire audio data from the vehicle audio bus and vehicle status data from the CAN bus;

[0060] determining a sounding state of the vehicle audio system based on the audio data and the vehicle status data;

[0061] According to the sound state, one or more control types for the functional modules of the power amplifier are selected from the preset power consumption atomization control set for execution;

[0062] determining a control mode of a control type to be executed based on the vehicle state data;

[0063] The preset power consumption atomic control set includes multiple independent power reduction controls for single functional modules of the power amplifier.

[0064] Here, we first define the concept of "atomic control". "Atomic control" refers to the independent control of a single functional module. The atomic control of the single functional module can be carried out in parallel with the atomic control of another functional module, but the two controls are independent of each other and do not affect each other. For the system, the atomic control of a single functional module can be called separately, which does not affect the system's atomic control of one or more other functional modules. For example, if an atomic control set includes three types of atomic controls, then these three atomic controls can be executed separately or in any combination, and there may be no time sequence relationship between them. The above-mentioned "power consumption atomic control set" includes one or more control types for the functional modules of the power amplifier, especially power consumption reduction control, which can be executed separately or in any combination. Through this atomic control form, each functional module of the power amplifier can be controlled independently and flexibly. When power consumption needs to be saved, it is not simply to reduce the efficiency of the power amplifier as a whole, resulting in a reduction in the sound effect of its output. Instead, the functional modules that are not currently in use can be selected to reduce power consumption, thereby achieving power consumption savings without affecting the current main working efficiency of the power amplifier. In this way, while saving power consumption, the function of the power amplifier is guaranteed to be realized without affecting the overall sound effect of the audio.

[0065] In one embodiment of the present invention, the power consumption atomic control set includes at least one of the following control types, especially includes at least three of the following control types, and preferably includes all of the following control types: PA (Power Amplifier) ​​chip power reduction control, DSP (Digital Signal Processing) chip power reduction control, Boost (boost) chip power reduction control, A2B (Automotive Audio Bus) chip power reduction control, peripheral circuit power reduction control. These five atomic controls are respectively used to reduce the power consumption required to enhance the input signal strength, the power consumption required for digital signal processing, the power consumption required for boosting, the power consumption required for the control and processing unit, and the power consumption required for the peripheral circuit. It should be understood that, depending on the structural form and actual application of the power amplifier, the power consumption atomic control set may also include atomic controls for other functional modules of the power amplifier in addition to the above five atomic controls.

[0066] It should be understood that each control type in the above-mentioned power reduction control can be implemented by adopting different control methods for a single functional module. In other words, the power reduction control of a single functional module is not actually the end point of atomic control. It can also be subdivided into more specific control methods for some of its algorithms or sub-functional modules. Taking the DSP chip power reduction control as an example, after determining the atomic control type for DSP chip power reduction, you can consider turning off one of the DSP dual cores to reduce the DSP chip power, or you can consider calling the accelerator dynamic switch to reduce the DSP chip power. These are all specific control methods of the DSP chip power reduction control type.

[0067] In one embodiment of the present invention, audio data includes data directly representing the theoretical sound state of the vehicle audio system, such as the volume and sound frequency, from the vehicle audio bus. Vehicle status data includes one or more of in-vehicle volume data, in-vehicle player playback status data, vehicle gear status data, vehicle door and window status data, and seat status data. Generally, the theoretical sound state of the vehicle audio system can be determined based solely on the audio data, but the actual sound state of the audio system is also affected by different vehicle states, such as the ambient noise level, the opening and closing status of the vehicle doors and windows, and the seating status of the seats. Taking the vehicle status data into account when determining the actual sound state of the audio system allows for a more accurate determination of the actual sound state of the vehicle audio system while taking into account external factors influencing the vehicle audio system. Furthermore, the vehicle status data allows for personalized matching of the power consumption atomization control method and adjustment of the degree and duration of the atomization control based on different vehicle states or in-vehicle seating conditions. This allows the power amplifier power consumption control method to be combined with other influencing factors besides the audio system, thereby improving the user experience when using the audio system. For example, the vehicle status data can be used to determine the occupancy status of different seats in the vehicle, and the power consumption of the DSP chip can be reduced by not loading the noise reduction algorithm in unoccupied seats.

[0068] In one embodiment of the present invention, the sounding state in the above power consumption control method is defined as two states, namely sounding or not sounding, which optionally corresponds to two characteristic values, such as 1 and 0. In this embodiment, "selecting one or more control types for functional modules of the power amplifier from a preset power consumption atomization control set according to the sounding state" includes the following steps:

[0069] Determine whether the audio system is emitting sound, and if not (i.e., a feature value of 0 is obtained based on the audio data and the vehicle status data), execute all controls in the power consumption atomization control set;

[0070] If so (i.e., a characteristic value of 1 is obtained based on the audio data and the vehicle status data), the sound type of the audio is determined based on the audio data, and corresponding controls are partially selected from the power consumption atomization control set for execution based on the sound type.

[0071] When the speaker is silent, all controls in the power consumption atomization control set are executed. This allows the power consumption of all functional modules to be safely reduced, or even some modules to be completely shut down. When the speaker is sounding, the corresponding atomization control can be selected based on the sound type.

[0072] In one embodiment of the present invention, the sound type of a speaker is defined as the different sounding modes of the speaker when it emits sound. In this embodiment, for example, it includes two sound types: a continuous sound type and an intermittent sound type. In an embodiment not shown, the sound type can also be classified as a sound state, in which case the sound state includes more than two sound states, such as a continuous sound state and an intermittent sound state. In this embodiment, if the speaker is determined to be emitting sound, the audio data is used to determine whether the speaker is in the continuous sound type or the intermittent sound type. If the speaker is in the intermittent sound type, the PA chip power reduction control, the DSP chip power reduction control, the Boost chip power reduction control, and the peripheral circuit power reduction control are executed. In other words, the power of all chips except the A2B chip can be appropriately reduced. If the speaker is in the continuous sound type, a control type is selected from the power consumption atomization control set based on the user's usage characteristics of the speaker at that time. It should be understood that the sound type can also include more than two sound types, which can be determined based on the configuration and function of the speaker and the user's requirements for control sensitivity and accuracy.

[0073] In one embodiment of the present invention, the above-mentioned usage characteristics refer to the audio usage mode (such as noise reduction, super theater mode, etc.) and usage parameters (such as volume, etc.) selected by the user. Through the audio usage mode or usage parameters selected by the user, it can be determined what kind of in-vehicle sound algorithm is loaded on the audio at this time. For example, if the user selects the noise reduction mode, it can be determined that the audio is loaded with the noise reduction algorithm at this time. The in-vehicle sound algorithm can process the output sound of the audio, for example, it can achieve effects such as echo elimination and noise reduction. The in-vehicle sound algorithm includes, for example, RNC (Road Noise Control), Upmix algorithm, sound wave algorithm, etc. In the case where the audio is loaded with a specific in-vehicle sound algorithm, it generally requires the support of high-power operation of the corresponding functional module.

[0074] Therefore, in this embodiment, “if the speaker is in the continuous sounding type, selecting the control type according to the user's usage characteristics of the speaker at this time” includes the following steps:

[0075] Determine the type of algorithm loaded by the speaker based on usage characteristics;

[0076] If the speaker is loaded with all algorithm types, only the Boost chip power reduction control is executed;

[0077] If the speaker has only some of the algorithm types loaded, a control type is selected from the power consumption atomization control set according to the unloaded algorithm types.

[0078] When all algorithm types are loaded, only the Boost chip does not need to run at high power, so you can consider reducing the power of the Boost chip. If the audio system has some algorithm types loaded, you can select the corresponding atomic control based on the unloaded algorithm types. This is because in the operation of general vehicle audio systems, there is a tendency not to save power and to load as many algorithms as possible to ensure the sound quality of the audio system, so as to always maintain a high standard of sound quality. In this case, the number of unloaded algorithms is usually less than the number of loaded algorithms, so determining the unloaded algorithms is more convenient than determining the loaded algorithms, and the computational complexity is also smaller.

[0079] In one embodiment of the present invention, “if the audio system has only some algorithm types loaded, selecting a control type from the power consumption atomization control set according to the unloaded algorithm types” includes the following steps:

[0080] If the unloaded algorithm type includes an upmixing algorithm, at least the Boost chip power reduction control and the DSP chip power reduction control are executed;

[0081] If the unloaded algorithm type includes a noise reduction algorithm, at least PA chip power reduction control, DSP chip power reduction control, and Boost chip power reduction control are executed.

[0082] Upmixing and noise reduction algorithms are the two primary types of algorithms loaded into automotive power amplifiers. Upmixing algorithms are used to blend two independent sound signals, making them sound more realistic and natural. Noise reduction algorithms used in automotive power amplifiers primarily include ANC (active noise cancellation) for the engine and RNC (active noise cancellation) for road noise. In automotive power amplifiers, upmixing and noise reduction algorithms are primarily run through the DSP. Therefore, even when neither upmixing nor noise reduction algorithms are loaded, DSP chip power reduction control can be implemented.

[0083] It should be understood that in the above-described power consumption control method, the atomic power reduction control performed on each functional module is implemented on the premise of ensuring the normal operation of the audio system and the audio quality of the audio system meets user requirements. The power reduction of the functional modules in this power consumption control method only affects the audio performance that exceeds the user's requirements or is excessively high, and does not affect the normal use of the audio system or the user's normal listening experience.

[0084] The power consumption control method of the present invention uses atomic control to reduce the power of each power module of the vehicle audio power amplifier, so that the power consumption of the power amplifier is reasonably reduced and the vehicle's cruising range is improved in response to different sound states, sound types and different user usage characteristics of the audio, while ensuring the normal operation of the audio and meeting the user's auditory needs.

[0085] Another aspect of the present invention provides a power consumption control system for a vehicle audio power amplifier. Referring to FIG2 , a block diagram of a power consumption control system according to an embodiment of another aspect of the present invention is shown. The power consumption control system 100 includes:

[0087] a calculation module 2, which determines the sound state of the vehicle audio according to the audio data and the vehicle state data;

[0088] a control module 3, which selects one or more control types for the functional modules of the power amplifier from a preset power consumption atomization control set according to the sound emission state, and determines a control mode for the control type to be executed according to the vehicle state data;

[0089] The preset power consumption atomic control set includes multiple independent power reduction controls for single functional modules of the power amplifier.

[0090] In one embodiment of another aspect of the present invention, the power consumption atomization control set includes at least one of the following control types: PA chip power reduction control, DSP chip power reduction control, Boost chip power reduction control, A2B chip power reduction control, and peripheral circuit power reduction control.

[0091] In an embodiment of another aspect of the present invention, the vehicle status data includes one or more of volume data, vehicle player playback status data, vehicle gear position data, vehicle door and window status data, and seat status data.

[0092] In an embodiment of another aspect of the present invention, the control module 3 selects a control type according to the sound state in the following manner:

[0093] Determine whether the speaker is making sound, and if not, execute all controls in the power consumption atomization control set;

[0094] If so, the sound type of the audio is determined based on the audio data, and corresponding controls are partially selected from the power consumption atomization control set for execution based on the sound type.

[0095] In an embodiment of another aspect of the present invention, if the control module 3 determines that the speaker is making sound, it determines whether the speaker is in a continuous sounding type or an intermittent sounding type based on the audio data; if the speaker is in an intermittent sounding type, the control module 3 executes PA chip power reduction control, DSP chip power reduction control, Boost chip power reduction control and peripheral circuit power reduction control; if the speaker is in a continuous sounding type, the control module 3 selects a control type from the power consumption atomization control set based on the user's usage characteristics of the speaker at this time.

[0096] In an embodiment of another aspect of the present invention, when the speaker is in the continuous sounding type, the control module 3 selects a control type from the power consumption atomization control set in the following manner:

[0097] determining the type of algorithm loaded by the speaker based on the usage characteristics;

[0098] If the speaker is loaded with all algorithm types, only the Boost chip power reduction control is executed;

[0099] If the speaker has only some of the algorithm types loaded, a control type is selected from the power consumption atomization control set according to the unloaded algorithm types.

[0100] In an embodiment of another aspect of the present invention, when the audio system has only some algorithm types loaded, the control module 3 selects a control type from the power consumption atomization control set in the following manner:

[0101] If the unloaded algorithm type includes an upmixing algorithm, at least the Boost chip power reduction control and the DSP chip power reduction control are executed;

[0102] If the unloaded algorithm type includes a noise reduction algorithm, at least PA chip power reduction control, DSP chip power reduction control, and Boost chip power reduction control are performed.
