Full-vehicle road rattle tuning
Full-vehicle road rattle tuning refers to the process of identifying and troubleshooting rattles from all vehicle systems on dedicated characteristic rattle evaluation roads at specified driving speeds. After all abnormal noise issues are identified, the vehicle’s Seat Rattle Index (SRI) is calculated based on the types of characteristic roads where rattles occur and rattle loudness, which is used to judge the overall anti-rattle performance of the vehicle.
