Embodiment 1

[0034] Such as Figure 1-7 As shown, the multifunctional vehicle pedestrian warning horn of the present invention is provided with a control box 7 in the housing 1, and the control box 7 is equipped with an input port, and the input port includes a power port, a horn signal port, a CAN bus high-level port, CAN bus low-level port, MCU processing unit U2 is set in the control box 7, MCU processing unit U2 is connected to the input port, MCU processing unit U2 includes a horn sound processing module and a reminder sound processing module, and the horn sound processing module is used To generate the horn sound source signal, the reminder sound processing module includes a reminder sound source generation module and a vehicle speed capture module. The sound source generation module and the vehicle speed capture module are synthesized by a synthesis unit to generate a reminder sound source signal. The horn sound processing module and the reminder sound processing module Use the same...

Embodiment 2

[0051] Such as Figure 8 Shown, the sounding method of the multifunctional automobile pedestrian warning horn of the present invention, comprises the following steps:

[0052] S1: The speaker is in the standby state after the power is turned on. When the speaker sound control port receives a high-level signal, the speaker sound program is executed immediately. When the MCU processing unit U2 receives the prompt sound start message sent by the CAN bus, it sends the message simultaneously according to CAN. The speed of the coming vehicle will automatically judge whether to execute the prompt sound program;

[0053] S2: When the speaker signal port receives a high-level signal, the MCU processing unit U2 will generate a speaker sound signal, and amplify the electrical signal through the output drive part to push the sounding mechanism to sound, and the sound will stop after the high level is cancelled. ;

[0054] S3: When the vehicle is driving, the on-board computer will send ...

Abstract

The invention discloses a multifunctional automobile pedestrian warning horn and a sound production method thereof and belongs to the technical field of electric automobile pedestrian warning. A shellis included, and internally provided with a control box; an input end port is arranged outside the control box, and an MCU processing unit is arranged in the control box, and connected with the inputend port; the MCU processing unit comprises a horn sound production processing module and a reminder sound production processing module; the horn sound production processing module is used for generating a horn sound source signal; the reminder sound production processing module comprises a reminder sound source generating module and a vehicle speed acquiring module; the sound source generating module and the vehicle speed acquiring module are used for generating a reminder sound source signal after being synthesized through a synthesizing unit; the horn sound production processing module andthe reminder sound production processing module are connected to an output driving unit through a same pin; and the output driving unit is connected with a sound production device. A pedestrian warning function and a lower-speed prompting sound prompting function of an electric horn are combined into one, and the problems occurring in the prior art are solved.

Description

technical field [0001] The invention relates to a multifunctional vehicle pedestrian warning horn and a sounding method thereof, belonging to the technical field of electric vehicle pedestrian warning. Background technique [0002] Article 8.6.1 of the "Technical Conditions for Motor Vehicle Operation Safety" requires that motor vehicles should have a continuously sounding horn to warn pedestrians in front of the vehicle. Article 12.13.2 stipulates that pure electric vehicles and plug-in hybrid When the speed is lower than 20km / h, it should be able to send out appropriate prompting sounds to people outside the vehicle. At present, electric vehicles use independent pedestrian warning electric horns and low-speed driving prompt sound devices, and separate horns and prompt sound devices are not conducive to control. The weight and cost of the car increase, which is not conducive to reducing the power consumption of electric vehicles and is not conducive to increasing the batter...
