Example Embodiment

[0020] The patent will be explained below with reference to the accompanying drawings. When the vehicle speed is slow and the distance between the pedestrians ahead is relatively close, the whistle will frighten the pedestrians and cause the pedestrians to panic and other bad emotions; and if the volume of the car horn is low, the When the car is driving fast and the pedestrians ahead are far away, the whistle cannot remind pedestrians in time. Therefore, this patent proposes an adaptive control method for the volume of the car horn based on the recognition of the pedestrian ahead.

[0021] The auto horn volume adaptive control system based on the recognition of the pedestrian target ahead of the present invention, such as figure 1 shown, including:

[0022] Vehicle speed detection module 100, pedestrian identification module 200, vehicle control module 300 and car horn; wherein, vehicle speed detection module 100 and pedestrian identification module 200 are both connected to...

Abstract

The invention discloses a front pedestrian target recognition based automobile horn volume self-adaption control system and aims to solve the problem that existing automobile horn volume is not adjustable. An automobile speed detection module acquires a real-time driving speed of an automobile through a Hall wheel speed sensor; a pedestrian recognition module acquires a front road image by the aid of an automotive foresight camera, detects information of pedestrians ahead of the automobile according to an image processing algorithm and judges distances between the automobile and the pedestrians ahead of the automobile; an automotive control module designs an automobile volume self-adoption adjustment algorithm according to automobile speed and pedestrian positions through a fitting relation model of volume decibels, the distances between the automobile and the pedestrians ahead of the automobile and the automobile speed to further adjust the automobile horn volume.

Description

technical field [0001] The invention relates to the field of auto parts, and more specifically, to an adaptive control system and a control method for the volume of a car horn based on target recognition of pedestrians ahead. Background technique [0002] With the continuous increase of the number of cars, the noise pollution of car horns is becoming more and more serious. No matter what the situation is, the traditional car horns can only emit a decibel-level beeping sound, which can easily frighten pedestrians and make people feel uncomfortable. The generation of bad emotions such as anxiety and panic does not meet the current development requirements of intelligent and humanized automobiles. Therefore, it is an urgent problem to be solved to design an invention so that it can be adaptively controlled based on the car horn volume of the front pedestrian target recognition, so that the car horn can be pronounced intelligently and humanized. Contents of the invention [0...
