Problems solved by technology

[0002] The electric car horn is made by the vibration of the metal diaphragm. The volume of the horn installed in the car is fixed, which will cause noise pollution in a quiet environment and seriously affect people's work and life.
If the driver uses manual adjustment, it will not only be impossible to adjust the volume in real time, but also increase troubles to normal driving
Conventional car speakers have the disadvantage of not being able to adaptively adjust the volume based on the surrounding environment, resulting in poor practicability and applicability

Embodiment Construction

[0016] The technical solution of the present invention will be described in detail below in conjunction with accompanying drawings. When the car travels to a quiet environment such as a school or hospital, the whistle will affect the lives of the surrounding residents. And if the car is equipped with a subwoofer, it cannot play a due warning role in a noisy environment. Therefore, the present invention proposes an adaptive control method for car horn volume mode based on environment recognition.

[0017] The composition diagram of the auto horn volume mode adaptive control system based on environment identification of the present invention is as follows figure 2 shown, including:

[0018] A GPS satellite positioning system module 100 for locating the position and motion state of the vehicle;

[0019] GIS geographic information system module 200 for analyzing, processing and querying spatial geographic data;

[0020] Electronic map generation module 300;

[0021] driver in...

Abstract

The invention discloses a car horn volume mode self-adaptive control method based on environmental identification. The method includes the following steps that in the driving process of a car, a GPS module positions the current driving state and the position coordinates of the car and meanwhile sends the positioned information to a GIS module and an electronic map generating module, the GIS module matches the position coordinates of the car with existing space data in the module to obtain the space position where the car is located currently, the space position is sent to the electronic map generating module which converts the information into a digital electronic map displayed on an interaction panel of a driver, and a car-mounted control unit analyzes the obtained space data, identifies the scene mode type which the current environment of the car belongs to and selects and sends volume mode signals to an execution unit. By means of the self-adaptive mode, safety of the car during driving in various environments is improved, and driving behaviors are more civilized.

Description

technical field [0001] The invention relates to a car horn control technology, in particular to an adaptive control method for a car horn volume mode based on environment identification. Background technique [0002] The electric horn of a car emits sound by the vibration of the metal diaphragm. The volume of the horn installed in the car is fixed, which will cause noise pollution in a quiet environment and seriously affect people's work and life. If the driver adopts manual adjustment, not only the volume cannot be adjusted in real time, but also it will cause trouble to normal driving. Conventional car speakers have the disadvantage of being unable to adaptively adjust the volume based on the surrounding environment, resulting in poor practicability and applicability. Contents of the invention [0003] Aiming at the problem that the volume of the current car horn cannot be automatically adjusted, the present invention proposes an adaptive control method for the volume m...
