Abstract

A method and device for testing belt durability of a BSG system, the method comprising: controlling a car to perform a plurality of working condition simulation tests sequentially on a car drum test stand, and in each working condition simulation test, the vehicle needs to complete the corresponding preset driving amount; calculate the total slip rate of the belt when all working condition simulation tests are completed; compare the total slip rate with the target slip rate, and when the total slip rate is less than the target slip rate, It is determined that the durability performance of the belt is acceptable. The belt durability test method in the invention is efficient and reliable, and greatly reduces the belt verification period.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a belt durability testing method and device of a BSG system. Background technique [0002] In recent years, in order to meet the requirements of national regulations on energy conservation, emission reduction and fuel consumption, various OEMs have begun to turn to the research and development of pure electric vehicles and hybrid vehicles and the application of various new technologies for energy conservation and emission reduction. Among them, BSG (Belt Driven StarterGenerator) technology is Low cost, relatively simple technology, obvious fuel-saving effect, etc., are favored by major OEMs. [0003] The BSG micro-hybrid system improves fuel efficiency and ultimately achieves the purpose of energy saving and emission reduction by realizing idle stop, quickly dragging the engine to above the idle speed to achieve quick start, and braking energy recovery. However, the frequent stop / star...
