Problems solved by technology

[0004] Therefore, due to the need to arrange additional acceleration sensors in the traditional solution, the additional cost and complexity of the vehicle are increased
At the same time, when the road condition information is relatively random, it is difficult to obtain the reference signal of the road condition, which increases the delay and error in data processing

Abstract

The invention relates to the technical field of noise reduction, in particular to a vehicle road noise reduction method and a system thereof, computer equipment for implementing the method and a computer readable storage medium. According to one aspect of the invention, the vehicle road noise reduction method comprises the following steps: collecting and storing road noise signals of different road conditions; collecting, identifying and processing road condition information of a road, and taking the identified and processed road condition information as a reference signal; determining a noisecontrol signal opposite to the road noise signal under the current road condition based on the reference signal and the road noise signal; and transmitting the noise control signal in a sound wave mode to counteract the road noise signal of the current road condition.

Description

technical field [0001] The present invention relates to the technical field of noise reduction, in particular to a noise reduction method and system for vehicle road noise, computer equipment and a computer-readable storage medium for realizing the method. Background technique [0002] With the improvement of people's living standards and the significant increase in the penetration rate of public vehicles, consumers have higher and higher requirements for the comfort of driving vehicles, and vehicles driving on the road are the state that customers have the most contact with vehicles in the process of using vehicles. The level of road noise during this process is one of the highest concerns for customers. [0003] At present, the commonly used solution for noise reduction technology for road noise is to arrange acceleration sensors on the suspension of the vehicle to collect relevant parameters as the basis for noise reduction, and use the microphone arranged in the car for ...
