Program-controlled variable-sound horn for motor vehicle

Abstract

The invention provides a program-controlled variable-sound horn for a motor vehicle, which is suitable for different application scenes. An existing motor vehicle horn is not friendly to non-motor vehicles or pedestrians due to the volume and tone problems. Especially for the elderly and children, the elderly and children are easily frightened, and sometimes disputes are generated. A program control module and a pressure section switch are introduced into a motor vehicle horn circuit, and the problems are effectively solved. The intention of a driver is distinguished through the pressure section switch, and the program control chip is used for controlling the loudspeaker to play different warning tones. When communicating with the motor vehicle, the switch is pressed forcibly, and normal whistling can be given out. When a non-motor vehicle or a pedestrian needs to be reminded, a soft and melodious prompt tone can be given out by lightly touching the switch so as to remind the non-motor vehicle or the pedestrian to pay attention to safety. According to the invention, the program control chip is adopted, and when a non-motor vehicle or a pedestrian is communicated and reminded, related information of a vehicle manufacturing enterprise or brand (for example, an XX automobile reminds people to pay attention to traffic safety) can be played, so that the popularity of the enterprise or the brand is improved.

Description

Technical Field

[0001] The present invention provides a program-controlled voice-changing horn for a motor vehicle, which is suitable for different application scenarios. Background Art

[0002] The application scenarios of motor vehicle horns can be roughly divided into two categories: 1. Communication reminders between motor vehicles; 2. Communication reminders between motor vehicles and non-motor vehicles or pedestrians. In the second application scenario, the existing motor vehicle horns are very unfriendly to non-motor vehicles or pedestrians due to volume and tone problems. Especially when facing the elderly and children, it is easy to cause fright. The present invention introduces a programmable control module and a pressure segment switch module into the motor vehicle horn circuit to effectively solve the above problems. Summary of the invention

[0003] The programmable voice-changing horn for motor vehicles proposed by the present invention uses a pressure segment switch to distinguish the intention of the driver, and uses a programmable chip to control the horn to play different prompt tones. When it is necessary to communicate with the motor vehicle, a normal prompt tone can be emitted by pressing the horn switch hard. When a non-motor vehicle or pedestrian needs to be reminded, a soft and pleasant prompt tone can be emitted by lightly touching the horn switch to remind the non-motor vehicle or pedestrian to pay attention to safety. The pressure segment switch can be implemented with a pressure variable resistor or piezoelectric ceramics.

[0004] Because the present invention uses a programmable chip, when communicating with non-motor vehicles or pedestrians, it can also play relevant information about the vehicle manufacturer or brand to enhance the visibility of the company or brand. For example, by lightly touching the switch, a reminder tone such as "XX car reminds you to pay attention to safety" can be issued, which can not only remind non-motor vehicles or pedestrians in a friendly manner, but also promote the high-end image of the car company or brand.

[0005] The present invention is particularly suitable for unmanned vehicles. When used in unmanned vehicles, the pressure segment switch is removed, and the vehicle system is directly connected, and different prompt tones are played by program control in different scenes. BRIEF DESCRIPTION OF THE DRAWINGS Figure Number: Figure 1 1. The pressure segment switch is used to distinguish the driver's intention. 2. The programmable chip controls the speaker to play different prompt tones.

Claims

1. A program-controlled variable sound and pitch horn for a motor vehicle (including an unmanned motor vehicle), characterized in that Different prompt messages can be played through program control according to different vehicle usage environments and scenarios.

2. A motor vehicle horn capable of playing information related to a vehicle manufacturer or brand, characterized in that By broadcasting relevant information of the vehicle manufacturer or brand through the loudspeakers of motor vehicles (including driverless motor vehicles), it can not only provide friendly reminders to non-motor vehicles or pedestrians, but also enhance the visibility and reputation of the company or brand.

3. A pressure segment switch for a motor vehicle horn, characterized in that Different circuits can be driven to work according to the pressing pressure, so that the motor vehicle horn emits different warning sounds.
