Horn intelligent system of unmanned vehicle

Abstract

A horn intelligent system of an unmanned vehicle disclosed by the present invention comprises a data acquisition unit, a data processing unit, a volume control unit and a horn, the output end of the data acquisition unit is electrically connected with the input end of the data processing unit, and the output end of the data processing unit is electrically connected with the input end of the volume control unit. The invention relates to the technical field of unmanned vehicle control systems. According to the unmanned vehicle horn intelligent system, a plurality of factors which influence the horn volume are selected as evaluation indexes, including real-time road conditions, real-time noise levels, visibility and the like, and a multi-factor fusion comprehensive evaluation system is established, so that compared with the single loudness of a traditional vehicle-mounted horn and compared with the single horn volume influence index in the past, the rationality of loudspeaker pronunciation and the accuracy and stability of evaluation are improved, and the loudspeaker volume range is sectionalized, so that the whistling area is expanded and the algorithm is effectively simplified on the premise of ensuring effective information interaction between the vehicle and the pedestrian.

Description

technical field [0001] The invention relates to the technical field of control systems for unmanned vehicles, in particular to an intelligent horn system for unmanned vehicles. Background technique [0002] With the rapid development of unmanned driving technology, unmanned vehicles are more and more used in human life today, and users have also put forward many higher requirements for electrical components on unmanned vehicles, such as the improvement of the horn function of unmanned vehicles . [0003] The horn of unmanned vehicles is frequently used as an important device for vehicles to release road occupancy information. It should have rich variations, such as the loudness of the whistle, etc., to adapt to various road conditions. The monotonous human-computer interaction mode of the horn of the unmanned vehicle not only reduces the experience and feeling accepted by pedestrians, but also increases the risk of vehicle driving, and even affects the prevention and contro...

AI Technical Summary

Problems solved by technology

The monotonous human-computer interaction mode of the driverless car horn not only reduces the experience and feelings accepted by pedestrians, but also increases the risk of driving vehicles, and even affects the prevention and control of urban traffic noise pollution

[0004] At present, the noise pollution of cars is the most difficult problem in the prevention and control of urban noise pollution, and the sound of car horns is the main factor leading to car noise pollution. , and indiscriminately honking horns near roads in residential areas, on campus, and on pedestrian roads will cause great trouble to the public
