[0037] See figure 1 , the first embodiment of the present invention provides a method for shielding vehicle noise, which is executed by an on-board controller and at least includes the following steps:

[0038] S1. When the car is started, play a preset covering sound through the vehicle broadcasting device within a preset instantaneous broadcasting time, and the preset covering sound refers to the sound or music emitted by the vehicle broadcasting device.

[0039] In this embodiment, the purpose of covering the noise of the relay is achieved by enabling the vehicle-mounted broadcasting device to play a preset cover sound at the moment when the car is started (ignited). Wherein, the preset covering sound refers to the sound or music emitted by the vehicle-mounted broadcasting device, which can be a power-on prompt sound, or a set beautiful music, and the preset instantaneous broadcasting time is extremely short, so that it can Instantly covering noises such as car startup and...

[0059] Corresponding to the method of the first embodiment of the present invention, the second embodiment of the present invention provides an automobile noise shielding system, comprising:

[0060] The vehicle-mounted controller is used to play a preset covering sound through the vehicle-mounted broadcasting device within a preset instantaneous broadcasting time when the car is started, and the preset covering sound refers to the sound or music emitted by the vehicle-mounted broadcasting device.

[0061] In this embodiment, the existing on-board controller can be directly used without additional design, and the software logic should be modified accordingly;

[0062] ① IGN signal interface is required;

[0063] ②If the current chip cannot respond to the ignition action in real time, a new DSP chip is required;

[0064] ③ The software storage space of the vehicle-mounted broadcasting device DA needs to have about 2MB of free space for audio storage.

Abstract

The invention discloses an automobile noise shielding method and system. The method includes: when the automobile is started, playing a preset covering sound through a vehicle-mounted broadcasting device within a preset instantaneous broadcasting time, and the preset covering sound refers to the Sound or music from the car audio system. The embodiment of the present invention can shield the noise emitted by the relay, which is beneficial to weaken the noise interference in the cockpit and improve the driving experience of the occupants.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile noise shielding method and system. Background technique [0002] During the start-up process of the electric vehicle, the relay will self-check and generate a lot of noise, which can be heard clearly by the occupants in the closed cockpit. The start-up of the car brings noise interference to the occupants and affects the occupants' driving experience. Contents of the invention [0003] The invention provides an automobile noise shielding method and system to solve the technical problem that the noise generated by the existing automobile starting relay affects the driving experience of the passengers. The invention can shield the noise emitted by the relay, which is beneficial to weaken the noise in the cockpit Interfere with and enhance the occupant's driving experience. [0004] In order to solve the above technical problems, in a first aspect, an embodiment...
