Abstract
Description
[0001] manual Technical Field
[0002] This invention relates to the field of vehicle audio technology, and more particularly to a fully automatic vehicle audio system with environmental perception function. Background Technology
[0003] With the rapid development of the automotive industry, people's requirements for car audio systems are no longer limited to sound quality alone, but also place greater emphasis on the integration of the audio system with the driving environment and a personalized experience. Traditional car audio systems often require users to manually adjust parameters such as volume and equalizer to adapt to different driving environments, which is cumbersome and ineffective. Therefore, developing a fully automatic car audio system that can automatically sense the environment and adjust the sound effects in real time is of great significance. Summary of the Invention
[0004] The purpose of this invention is to provide a fully automatic in-vehicle audio system with environmental perception function to solve the problems mentioned in the background art.
[0005] The technical solution adopted in this invention is: a fully automatic vehicle audio system with environmental perception function, including an environmental perception module, an audio processing module, an audio output module, and a central control module.
[0006] Environmental perception module
[0007] This module consists of a sound sensor, a light sensor, and a temperature sensor. The sound sensor detects noise levels during vehicle operation, including engine noise, road noise, and wind noise, and can also recognize voice commands from passengers inside the vehicle. The light sensor senses the light intensity inside and outside the vehicle, thus determining whether it is daytime, nighttime, or a special environment such as a tunnel. The temperature sensor measures the temperature inside and outside the vehicle, providing a reference for adjusting the audio system.
[0008] These sensors are characterized by high precision, high sensitivity, and fast response. For example, the sound sensor has a detection frequency range of 20Hz to 20kHz and a sensitivity of over -50dB, enabling it to accurately capture subtle changes in sound. The light sensor's response wavelength range covers the visible light region, with a measurement accuracy within ±5%, ensuring accurate perception of light intensity. The temperature sensor has a measurement range from -40℃ to 85℃ and a measurement accuracy of ±1℃, adapting to various extreme temperature environments.
[0009] Audio processing module
[0010] This module adaptively adjusts and optimizes the input audio signal based on environmental information collected by the environmental perception module. It includes an audio equalizer, volume controller, and sound effects processor.
[0011] The audio equalizer allows for independent adjustment of multiple frequency bands, such as ±12dB adjustment for low, mid, and high frequencies, enabling precise control over audio frequency response to adapt to different acoustic environments. The volume controller automatically adjusts the speaker volume based on ambient noise levels, with an adjustment range of 0dB to 90dB and a response time of less than 50ms, ensuring rapid and smooth volume adjustment in response to noise changes and preventing user discomfort. The sound effects processor incorporates multiple sound effect modes, such as rock, pop, classical, and jazz, automatically selecting and applying appropriate modes based on different environmental scenarios, such as highways, city streets, and rural roads, providing users with a more immersive listening experience.
[0012] Audio output module
[0013] Composed of multiple speakers distributed in different locations within the vehicle, such as the front doors, rear doors, center console, and trunk, it provides a comprehensive audio experience. Each speaker is meticulously designed and tuned, with a wide frequency response range from 20Hz to 20kHz and an output power exceeding 50W, ensuring clear and full sound across a wide range of audio frequencies.
[0014] Central control module
[0015] As the core of the entire system, it is used to receive and process information from the environmental perception module, control the working mode of the audio processing module, and send the processed audio signal to the speaker output module.
[0016] The central control module employs advanced algorithms and models, such as deep learning-based neural network algorithms and adaptive control models, enabling it to analyze massive amounts of environmental data in real time and make accurate decisions and responses within an extremely short time (typically less than 100ms). Through deep understanding and analysis of environmental information, the central control module can intelligently adjust various parameters of the audio system, achieving fully automatic intelligent control and providing users with a consistently high-quality audio experience.
[0017] In addition, this car audio system is equipped with interfaces for communicating with external devices, such as Bluetooth and USB, which facilitates connection with the vehicle's onboard computer, mobile terminals, and other devices to achieve data sharing and remote control.
[0018] Compared with the prior art, the beneficial effects of the present invention are: the present invention collects environmental information inside and outside the vehicle in real time through the environmental perception module, and combines advanced audio processing technology and intelligent control algorithm to realize fully automatic intelligent adjustment of the in-vehicle audio system, providing users with a more comfortable and personalized listening experience in different driving environments, and improving driving safety and enjoyment. Attached Figure Description
[0019] Figure 1 This is a schematic diagram of the system structure of the present invention. Detailed Implementation
[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0021] like Figure 1 As shown, the fully automatic vehicle audio system with environmental perception function of the present invention includes an environmental perception module 1, an audio processing module 2, an audio output module 3, and a central control module 4.
[0022] During actual installation and use, the sensors in the environmental perception module 1 should be installed in appropriate locations within the vehicle to ensure accurate collection of environmental information. The audio processing module 2 and the central control module 4 can be integrated into the vehicle's audio head unit, while the speakers in the audio output module 3 are rationally arranged according to the vehicle's internal structure.
[0023] During system initialization, users can set basic parameters according to their preferences, such as the default volume range and preferred sound effect modes. While the vehicle is in motion, the environmental perception module 1 continuously collects environmental information and transmits it to the central control module 4. The central control module 4 analyzes and processes this information and then sends control commands to the audio processing module 2 to adjust the audio parameters. The processed audio signal is finally played out through the speaker output module 3.
[0024] For example, when a vehicle enters a tunnel, the light sensor detects a sudden drop in light intensity, and the central control module 4 automatically adjusts the audio volume and sound effects, enhancing the low-frequency response to create a richer atmosphere. When the vehicle is traveling on a highway, increased ambient noise triggers the volume controller to automatically increase the audio volume, ensuring the music is clearly audible.
[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
