Abstract
Description
Technical Field
[0001] The invention relates to a noise reduction control method for an automobile horn, belonging to the technical field of automobiles. Background Art
[0002] Analyzing from the control circuit of the car horn of existing cars, the control circuit of existing cars is basically the same, which consists of a horn button, a horn relay, an electric horn and a power supply. When the driver presses the horn button, the horn relay is turned on, the power supply supplies power to the electric horn, and the electric horn honks. The longer the button is pressed, the greater the noise impact.
[0003] According to the provisions of the Road Traffic Safety Law of the People's Republic of China, vehicles are not allowed to blow their horns in areas or sections where honking is prohibited. In addition, no other regulations are made. Along with the increase in the number of cars, the noise pollution caused by honking car horns is also becoming more and more serious. Especially in sections with heavy traffic or congested traffic, the noise caused by vehicles blowing their horns is more obvious. How to solve this problem, no solution is provided in the prior art. Through searching, it can be seen that the technical solutions at home and abroad are all to obtain the vehicle position by GPS positioning. If located in the area where honking is prohibited, then the vehicle is controlled not to blow its horn. This obviously can not solve the noise pollution problem caused by honking the horn in the non-honking area in reality. Summary of the Invention
[0004] In view of the above problems existing in the prior art, the purpose of the present invention is to provide a noise reduction control method for automobile horns. When honking is required in non-prohibited areas, the method follows the principle of being short and polite to prevent excessive honking from causing noise pollution.
[0005] To achieve the above objectives, the present invention adopts a technical solution: a method for controlling noise reduction of a vehicle horn, comprising adding a control component to a horn button, a horn relay, an electric horn, and a power supply. The control component includes a signal acquisition module, a main processor, and an output module. The signal acquisition module has an input connected to one end of the horn button to acquire the closed state of the horn button. One end of the horn relay coil is connected to one end of the power supply, one end of the electric horn is connected to one end of the power supply, and a switch of the horn relay connects the electric horn and the other end of the power supply. When the horn button is closed, the signal acquisition module outputs a signal to the main processor. The main processor is connected to the output module, which is connected to the horn relay coil and the other end of the power supply. The main processor has a built-in timer. For a press duration of ≤1.5s, the output module controls the horn relay coil to energize for 0.5s. For a press duration of >1.5s, the output module counts whether the press duration reaches a multiple of 1.5s. The output module controls the horn relay coil to energize for 0.5s, then delay for 1s, and then energize again for 0.5s, for a maximum of three energization cycles.
[0006] Furthermore, the horn relay and the control component are integrated in a housing, and each lead-out terminal pin is output in a plug-in structure and is located outside the housing.
[0007] Furthermore, at least six lead-out pins are provided, namely, two signal acquisition module lead-out pins, two power supply lead-out pins, and two speaker lead-out pins.
[0008] Furthermore, two cavities are provided in the housing, wherein one cavity is used for mounting the coil and components of the horn relay, and the other cavity is used for mounting the circuit board of the control assembly.
[0009] Furthermore, the signal acquisition module is a current signal acquisition module.
[0010] Compared with the prior art, the beneficial effects of the present invention are: simple structure, easy production and installation, strict control of the duration and number of whistles, and the noise reduction effect is self-evident. BRIEF DESCRIPTION OF THE DRAWINGS
