Abstract

The invention discloses a noise evaluation system for an electronic parking brake system, and belongs to a technology in the field of system testing. The noise evaluation system comprises a driving control module, a first signal acquisition module, a signal processing module and a noise evaluation module, wherein the driving control module is connected with the electronic parking brake system so as to control the electronic parking brake system to perform an operation on brake pads of a vehicle; the first signal acquisition module acquires a noise signal generated by the electronic parking brake system when operating the brake pads; the signal processing module is connected with the first signal acquisition module and used for receiving the noise signal and calculating the overall sound pressure level of the electronic parking brake system; and the noise evaluation module is connected with the signal processing module and used for comparing the overall sound pressure level with a preset noise index and outputting a comparison result. The technical scheme has the beneficial effects that an operator is not required to have a lot of detection experience and relevant professional knowledge, the noise evaluation system is applicable to online detection, the detection range is wide, the operation is simple, and the cost is low.

Description

technical field [0001] The invention relates to a technology in the field of system testing, in particular to a noise evaluation system of an electronic parking brake system. Background technique [0002] Improving the NVH (Noise Vibration Harshness) performance of automobiles has already become one of the key research contents of the automobile industry. The control of NVH of the whole vehicle often starts from the NVH of auto parts. Improving the NVH performance of auto parts has become an effective way to improve the competitiveness of products in the automotive industry. [0003] With the development of automobile intelligence, it is the general trend to replace the traditional IPB (Integrated Parking System) with Electronic Parking Brake (EPB). Therefore, it will be particularly important to control the noise level of EPB. [0004] At present, there is no relevant EPB noise evaluation system for EPB noise evaluation. [0005] The strength of a sound is usually measur...
