In this embodiment, the adaptive vehicle sound adjusting method includes the following steps:
step S10: and acquiring current driving information.
It should be understood that the main body of the method of the present embodiment may be a vehicle sound adaptive adjusting device with data processing, network communication and program running functions, such as a vehicle computer or a vehicle controller, or other devices or devices capable of implementing the same or similar functions, and the following is given by taking the sound adaptive adjusting device as an example, which is not limited in this embodiment.
It should be noted that the current driving information may be driving information during driving of the vehicle, for example, the current driving information may be information of current vibration, current noise, current environment, current time, current temperature, current road condition, engine operating state, or current vehicle speed.
Step S20: and determining a vehicle sound mode according to the current driving information.
It should be noted that the vehicle sound mode may be a mode containing different sound adjustment strategies, for example, the vehicle sound mode may be a noise reduction sound mode, a comfort sound mode, a music enhancement mode, or a sports sound mode. The sound adjusting device can adaptively switch the vehicle sound mode according to the current driving information, and can also manually adjust and switch the vehicle sound mode according to the user.
It should be understood that, in order to perform adaptive adjustment on the vehicle sound, the sound adjusting apparatus of the present embodiment determines the vehicle sound mode according to the current driving information, and then determines the corresponding sound adjusting strategy according to the current vehicle sound mode to perform vehicle sound adjustment.
In a specific implementation, for example, the sound adjusting apparatus determines that the current driving noise is too strong according to the current driving information, thereby determining the vehicle sound mode as a noise reduction sound mode, and determines a corresponding noise adjustment strategy according to the noise reduction sound mode.
Step S30: and acquiring a sound adjusting strategy corresponding to the vehicle sound mode, and adjusting the sound according to the sound adjusting strategy.
It should be noted that the sound adjusting strategy may be a strategy for adjusting the vehicle sound, and the sound adjusting device determines different sound adjusting strategies according to different vehicle sound modes, for example, a sound adjusting strategy corresponding to a noise reduction sound mode is a noise adjusting strategy; the sound adjusting strategy corresponding to the comfortable sound mode is an environment simulation strategy; the sound adjusting strategy corresponding to the music enhancement mode is a sound quality improvement strategy; the sound adjustment strategy corresponding to the sports sound mode is an engine sound emission strategy.
It should be understood that, in different driving scenes of an automobile, the requirements of a user for the automobile sound are different, and therefore different sound adjustments need to be performed according to different scenes, in this embodiment, the sound adjustment device determines a vehicle sound mode required by the current user according to current driving information (for example, when the noise is strong, switches to a noise reduction sound mode), acquires a sound adjustment policy corresponding to the vehicle sound mode (for example, acquires a noise adjustment policy corresponding to the noise reduction sound mode), and finally performs sound adjustment according to the sound adjustment policy.
In a specific implementation, for example, the sound adjusting apparatus determines that the current vibration and the current noise are strong according to the current driving information, determines that the user needs a quiet driving environment, thus determines that the vehicle sound mode is the noise reduction sound mode, then obtains a noise adjustment policy corresponding to the noise sound mode, and performs noise reduction adjustment according to the noise adjustment policy.
Further, in order to improve the quality of music, the step S30 may include:
when the current sound mode is a music enhancement mode, acquiring currently played music;
and determining a tone quality improvement strategy corresponding to the music enhancement mode according to the currently played music, and adjusting tone quality according to the tone quality improvement strategy.
It should be noted that the sound quality improvement strategy may be a strategy for improving the sound quality of the currently played music, and the sound adjusting device may improve the sound quality by increasing the output power of the speaker of the currently played music, or may improve the sound quality by increasing the sampling rate output of the music playing.
Further, for the driving experience of the user, the step S30 may include:
when the current sound mode is a motion sound mode, determining the current engine state and the current accelerator state according to the current driving information;
and determining an engine sounding strategy corresponding to the motion sound mode according to the engine state and the current accelerator state, and performing engine sounding regulation according to the engine sounding strategy.
It should be noted that the current engine state may be state information such as a current rotation speed of the engine, the current accelerator state may be a current accelerator depth of the vehicle, and the engine sounding strategy may be a strategy for releasing engine noise that increases with the vehicle speed.
It should be understood that, in order to improve the driving experience of the user, the sound adjusting device of the present embodiment simulates the engine to generate sound according to the current engine state and the current vehicle speed so as to meet the driving pleasure of the user, for example, when the current vehicle speed is 80km/h and the current engine speed is full load, the sound adjusting device simulates the operating sound of the 12-cylinder engine according to the current vehicle speed and the current engine state so as to meet the user requirement, so as to improve the driving experience of the user.
In the embodiment, the current driving information is acquired, the vehicle sound mode is determined according to the current driving information, the sound adjusting strategy corresponding to the vehicle sound mode is acquired, and sound adjustment is performed according to the sound adjusting strategy. According to the method and the device, the vehicle sound mode is determined according to the current driving information, the sound adjusting strategy corresponding to the vehicle sound mode is obtained, and sound adjustment is carried out according to the sound adjusting strategy, so that the vehicle sound is accurately and adaptively adjusted, and the driving experience of a user is improved.
Referring to fig. 3, fig. 3 is a schematic flow chart of a second embodiment of a vehicle sound adaptive adjustment method according to the present invention.
Based on the first embodiment, in this embodiment, the step S30 includes:
step S31: and when the current sound mode is the noise reduction sound mode, determining current vibration information and current noise information according to the current driving information.
It should be noted that the noise reduction mode may be a sound adjustment mode for reducing vehicle noise, and the sound adjustment device may be switched to the noise reduction mode through user adjustment, or may be adaptively switched to the noise reduction mode according to current vibration information and noise information.
The current vibration information may be vibration received during current driving of the vehicle, and the sound adjusting apparatus may collect the current vibration information of the vehicle through an internally integrated or externally connected vibration sensor. The current noise information can be noise inside a vehicle body in the current driving process of the vehicle, the sound adjusting device can collect the noise information inside the vehicle through a sound sensor which is internally integrated or externally connected, and the noise information can comprise information such as noise frequency and noise size inside the vehicle.
It should be understood that the sound adjusting apparatus may collect current noise information of the vehicle through a sound sensor installed in a passenger compartment in the vehicle. The sound adjusting apparatus may collect current vibration information of the vehicle through a vibration sensor mounted at a wheel.
It should be understood that, in the driving process of the vehicle, due to the influence of road conditions or environmental factors, the influence of vibration and noise on the vehicle is large, at this time, noise reduction adjustment needs to be performed on the vehicle, so that the driving process of the user is not interfered by the noise.
Step S32: and determining the vibration excitation frequency according to the current vibration information.
It should be noted that the vibration excitation frequency may be a vibration excitation frequency transmitted from the road surface during the running of the vehicle.
It should be understood that the sound-conditioning device may collect a first vibration signal transmitted from the road surface by means of a vibration sensor arranged at each wheel caliper of the vehicle, collect a second vibration signal filtered by the suspension by means of a vibration sensor arranged at the body above the wheels, and determine the excitation frequency of the vibration transmitted from the road surface during the running of the vehicle from the first vibration signal and the second vibration signal.
Step S33: and determining a noise regulation strategy corresponding to the noise reduction sound mode according to the vibration excitation frequency and the current noise information, and carrying out noise reduction regulation according to the noise control strategy.
It should be noted that the noise adjustment strategy may be a strategy for adjusting the noise to which the vehicle is subjected. For example, the sound adjusting apparatus may play noise reduction sound in anti-phase with the current noise through a speaker installed in the vehicle.
It should be understood that the sound adjusting device determines the main cause of the noise to which the vehicle is subjected according to the vibration excitation frequency and the noise information, and if the vibration influence is large, the rigidity and damping of the main suspension of the vehicle are controlled to adjust the current noise of the vehicle; if the influence of the environmental noise is large, the noise reduction sound in the phase opposite to that of the environmental noise is played through a loudspeaker arranged in the vehicle so as to adjust the current noise of the vehicle.
In a specific implementation, for example, the sound adjusting apparatus analyzes the vibration excitation frequency and the current noise information, determines that the environmental noise is a main noise source, determines a noise adjustment policy corresponding to the noise reduction sound mode, and performs noise adjustment according to the noise control policy: the noise reduction sound in phase opposition to the ambient noise is played through a speaker mounted inside the vehicle to adjust the current noise of the vehicle.
Further, in order to adjust the noise reduction adjustment according to real time, the step S33 may include:
step S331: monitoring current vibration information and current noise information in a noise reduction adjusting process;
step S332: and stopping noise reduction adjustment when the current vibration information and the current noise information in the noise reduction adjustment process are monitored to meet preset conditions.
It should be noted that the preset adjustment may be a condition set in advance for determining the degree of influence of noise.
It should be understood that, in order to feed back and correct the noise reduction adjustment process in real time, the sound adjustment device in this embodiment stops noise reduction adjustment by monitoring the current vibration information and the current noise information in the noise reduction adjustment process, when monitoring that the current vibration information and the current noise information in the noise reduction adjustment process meet the preset conditions, thereby implementing noise reduction adaptive adjustment.
In this embodiment, when the current sound mode is the noise reduction sound mode, current vibration information and current noise information are determined according to the current driving information, a vibration excitation frequency is determined according to the current vibration information, a noise adjustment strategy corresponding to the noise reduction sound mode is determined according to the vibration excitation frequency and the current noise information, and noise reduction adjustment is performed according to the noise control strategy. According to the method and the device, the noise regulation strategy corresponding to the noise reduction sound mode is determined according to the current vibration information and the current noise information, so that the noise regulation of the vehicle is realized, the noise influence of a user in the driving process is reduced, and the driving experience of the user is improved.
Referring to fig. 4, fig. 4 is a flowchart illustrating a method for adaptively adjusting a vehicle sound according to a third embodiment of the present invention.
Based on the first embodiment, in this embodiment, the step S30 may include:
step S301: and when the current sound mode is a comfortable sound mode, determining environmental information according to the current driving information.
It should be noted that the comfort sound mode may be a mode for simulating an environmental sound according to a scene, and the sound adjusting device may be actively switched to the comfort sound mode by a user, or may be adaptively switched to the comfort sound mode according to a current location, a current vehicle speed, a current weather, or a current time. The environment information may be an environment of a current driving process of the vehicle, and the environment information may include information of a current location, a current temperature, a current weather, a current time, and the like.
Step S302: and acquiring the analog sound type corresponding to the environment information.
It should be noted that the analog sound type may be a sound type generated by the sound adjusting apparatus based on the environmental information, such as a sound of wave slapping, a sound of bird calling by insects, or a sound of wind blowing wheat waves.
It should be understood that, in order to accurately simulate the corresponding sound according to the environment information, the sound adjusting device of the present embodiment determines the type of the corresponding simulated sound according to the environment information, such as the current location, the current time, the current vehicle speed, the current weather, and the current road condition.
It should be noted that the sound adjusting apparatus needs to establish a corresponding analog sound type mapping relationship in advance according to the environment information, for example, when the vehicle is near the seaside or the river, the corresponding analog sound type is a sea wave slapping sound or when the vehicle is driving in a rural field, the corresponding analog sound type is a howling sound.
The sound adjusting device can determine the sound rhythm type of the analog sound according to the current vehicle speed, for example, the sound rhythm type corresponding to the vehicle speed of less than 40km/h is a mild comfortable rhythm, the sound rhythm type corresponding to the vehicle speed of 40-60km/h is a relaxed and cheerful sound, the sound rhythm type corresponding to the vehicle speed of 60-100km/h is a dynamic and hypertonic rhythm, or the sound rhythm type corresponding to the vehicle speed of more than 100km/h is a slightly jerky sound rhythm.
The sound adjusting device may determine the sound artistic style of the analog sound according to the current weather, for example, the sound artistic style corresponding to the current weather is warm-color type sound when the current weather is sunny, or the sound artistic style corresponding to the current weather is dark-gray type sound when the current weather is cloudy, and the like.
The sound adjusting device may determine the sound rhythm type of the analog sound according to the current driving time, for example, when the current driving time is less than 0.5h, the corresponding sound rhythm type is cheerful sound, when the current driving time is 0.5-1h, the corresponding sound rhythm type is comfortable music, when the current driving time is 1-3h, the corresponding sound rhythm type is slightly dynamic sound, or when the current driving time exceeds 3h, the corresponding sound rhythm type is excited sound.
In a specific implementation, for example, the sound adjusting apparatus determines, based on the environment information, that the current position is located at the seaside, the current vehicle speed is 60km/h, and the current weather is a sunny day, and thus determines that the simulated sound type is a sea wave slapping sound, the sound rhythm type is a relaxed and cheerful type rhythm, and the sound artistic style is a warmer color type sound.
Step S303: and determining an environment simulation strategy corresponding to the comfortable sound mode according to the simulation sound type, and adjusting the environment sound according to the environment simulation strategy.
It should be noted that the environment simulation strategy may be a strategy for playing the corresponding music according to the simulated sound type.
In a specific implementation, for example, the sound adjusting apparatus determines, according to the environment information, that the current position is located at the seaside, the current vehicle speed is 60km/h, and the current weather is a sunny day, and therefore determines that the simulated sound type is a sea wave slapping sound, the sound rhythm type is a relaxed and cheerful rhythm, and the sound artistic style is a warmer color type sound, and then formulates an environment simulation strategy according to the simulated sound type, the sound rhythm type, and the sound artistic style, and plays the corresponding environment simulation sound according to the environment simulation strategy.
Further, in order to accurately perform the ambient sound adjustment, the step S303 may include:
determining the current vehicle speed and the current driving time according to the current driving information;
determining a sound rhythm type according to the current vehicle speed and the current driving duration;
and determining an environment simulation strategy corresponding to the comfortable sound mode according to the sound rhythm type and the simulation sound type, and adjusting the environment sound according to the environment simulation strategy.
It should be noted that the current vehicle speed may be a current traveling speed of the vehicle. The above-described current driving time period may be a time period during which the vehicle is running. The sound rhythm type can be the rhythm type of the environmental sound, and the sound rhythm type can be a light and comfortable sound rhythm, a light and cheerful sound rhythm or a slightly rapid sound rhythm and the like.
In this embodiment, when the current sound mode is the comfort sound mode, the environment information is determined according to the current driving information, the simulated sound type corresponding to the environment information is acquired, the environment simulation strategy corresponding to the comfort sound mode is determined according to the simulated sound type, and the environment sound is adjusted according to the environment simulation strategy. According to the method and the device, the corresponding simulated sound type is obtained according to the environment information, the environment simulation strategy corresponding to the comfortable sound mode is determined according to the simulated sound type, and the environment sound is adjusted, so that the environment sound is adjusted in the driving process, and the driving experience of a user is improved.
