Software upgrading method of automobile noise reduction system, and automobile noise reduction system

Abstract

In order to improve the upgrading speed of a noise reduction system, the invention provides a software upgrading method of an automobile noise reduction system and the automobile noise reduction system. The noise reduction system comprises a collection device, a transfer storage module, a noise reduction module and an A2B bus device, the noise reduction module comprises a noise reduction unit, andthe method comprises the steps that the transfer storage module obtains an upgrading operation instruction and sends a first upgrading instruction to the noise reduction unit through the A2B bus device; the noise reduction unit responds to the first upgrading instruction and determines an upgrading target object in the noise reduction module according to the first upgrading instruction; the noisereduction unit acquires state information and judges whether the upgrading target object meets an upgrading condition according to the state information; if the upgrading condition is met, the noisereduction unit sends a second upgrading instruction to the transfer storage module through the A2B bus device; the transit storage module responds to the second upgrading instruction and sends a software upgrading packet to the noise reduction unit through the A2B bus device according to the second upgrading instruction; and the noise reduction unit controls the upgrading target object to upgradeaccording to the software upgrading package.

Description

technical field [0001] The invention relates to the field of automobile electronic appliances, in particular to a software upgrading method of an automobile noise reduction system and the automobile noise reduction system. Background technique [0002] Due to the development of technology trends, more and more automotive electronic actuators (ECUs) need to frequently update or upgrade the internal execution software of the ECU. So currently there is a method for upgrading software through traditional vehicle body buses (such as CAN bus, LIN bus). [0003] In the automotive noise reduction system, the transmission speed of the currently used body electronic buses, such as the CAN bus and the LIN bus, is generally slow, resulting in a slow upgrade speed of the ECU. Moreover, in the current automotive noise reduction system, generally, only a single ECU of the noise reduction system can be upgraded, and the upgrade efficiency is low. [0004] Therefore, it is necessary to pro...
