Method, system and active sound device for optimizing acoustic environment in vehicle

ActiveCN109842840BImprove driving experienceConducive to defects with weak subjective feelingsLoudspeaker signals distributionEngineeringVocal cues
The invention discloses a method for optimizing a sound environment in a vehicle, which comprises the following steps of: establishing corresponding relations between different working conditions andoptimized sound signals in advance according to target sound signals in an ideal sound environment, and storing the optimized sound signals in different working conditions as active sound signals; obtaining the current working condition of the vehicle; determining an active sound signal required under the current working condition according to the corresponding relationships between the differentworking conditions and the optimized sound signals; and playing the active sound signal to form the target sound signal in the vehicle so as to optimize the sound environment in the vehicle to an ideal state. The method is simple and practical, not only is beneficial to timely playing of the active sound signal to obtain an ideal in-vehicle sound environment, but also can achieve the purpose of carrying out sound prompting according to different working conditions, overcomes the defect that subjective feelings of a user on the working condition of the vehicle are weak due to the fact that equipment operation tends to be electronized, and improves overall driving and riding experience of the user. The invention further provides a system for optimizing the in-vehicle sound environment and active sound equipment.

Method and device for sound prompting outside a vehicle

The embodiment of the invention provides a vehicle exterior sound prompting method. The vehicle exterior sound prompting method comprises the following steps: step 104, collecting sounds in an environment outside a vehicle; step 106, identifying whether a preset sound signal is included in the collected sounds; and if the preset sound signal is included, further determining the type of a sound source, wherein the preset sound signal is a sound signal affecting vehicle running; step 108, when the identified sounds contain the preset sound signal, positioning the sound source transmitting the preset sound signal, and determining the position and running direction of the sound source relative to the vehicle; and step 110, prompting a driver of the type of the identified sound source and the position of the sound source relative to the vehicle. The vehicle exterior sound prompting method provided by the invention has the advantages that an effect that the function provides assistance for the driver in driving can be improved, therefore, more accurate service can be provided for the driver, the demand of a user can be flexibly met, assisted driving applicability realizes a more diversified effect, the running safety can be enhanced, and the degree of user experience is enhanced.

Water heater and water heater control method

ActiveCN108006986BAvoid repeated sound promptsPlay the role of sound promptFluid heatersThermodynamicsEngineering
The invention discloses a water heater and a water heater control method, wherein the water heater control method comprises the following steps: using a temperature detection device to detect the water temperature in the inner tank of the water heater; using a comparison module to compare the water temperature detected by the temperature detection device with a first Preset water temperature; when the detected water temperature is greater than or equal to the first preset water temperature, determine whether the detected water temperature is greater than or equal to the first preset water temperature for the first time; if so, the controller controls the heating device to stop heating, and controls the sound prompt device to issue a sound prompt ; If not, the controller only controls the heating device to stop heating. In the present invention, the timing of the voice prompt is set to be heated to the first preset temperature for the first time, so as to avoid the phenomenon that the voice prompt device repeatedly sends out the voice prompt when the temperature reaches the first preset temperature again during the heat preservation process, so that the voice prompt device does not It will affect the user's life due to repeated prompts, so that the user can use the water heater more comfortably and quietly.
