Vehicle, car horn system and control method thereof

Abstract

The invention provides a vehicle, a car horn system and a control method thereof, wherein the car horn control system comprises: a horn; an identification module for identifying the current road conditions of the car to generate an identification signal; a horn switch for receiving the driver's Trigger command, wherein the trigger command includes a trigger command of long-pressing the horn switch and a trigger command of short-pressing the horn switch; the controller, the controller is respectively connected with the horn, the identification module and the horn switch, and the controller receives the short-pressing of the horn switch. After triggering the instruction, the volume and / or tone of the sound emitted by the speaker is controlled according to the identification signal. The car horn system of the invention can effectively reduce the noise pollution of the car while exerting the safety warning function of the car horn, realize multi-level control according to the needs of users, and has higher safety and reliability.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a car horn system, a control method thereof and a vehicle with the car horn system. Background technique [0002] With the rapid growth of the number of motor vehicles, road traffic noise has become the main source of noise pollution in cities. For example, the sound of vehicle horns not only affects people's normal life, study and work, but also brings great harm to human health. [0003] At present, in the known technology, ordinary cars only provide a monotonous horn and its control system, which can greatly improve the driving safety of the car by controlling the horn mechanism on the steering wheel to emit sound. But, the sharp sound that car horn sends easily makes people irritated, and, when vehicle driver reminds others to avoid by horn, can bring trouble or fright to pedestrian or cyclist, may cause traffic accident or dispute. Therefore, noise pollution should be redu...

AI Technical Summary

Problems solved by technology

[0005] But the shortcoming that known technology exists is: the sound that the horn system of common car sends is monotonous, sharp and harsh, causes serious noise pollution

In addition, in the above-mentioned disclosed device for reducing noise pollution from car horns and its application, the sensor itself is subject to the influence of the car body itself and the environmental noise, so it cannot accurately identify the noise source, and the effect is not good.

The above disclosed system and method for preventing automobiles from honking in the no-honking area directly shields the horn system according to the no-honking area, which may cause the driver to be unable to distinguish the fault of the horn system, and the invalid horn may lead to traffic accidents in emergency situations, which has great potential. security risks
