As one of the most direct ways for users to perceive overall vehicle quality, squeak and rattle has become a key consideration for consumers when purchasing a vehicle. Therefore, evaluating squeak and rattle after full vehicle assembly has become an essential part of vehicle quality assurance.
Drawing on years of professional experience and core technologies accumulated in acoustic laboratories and vehicle NVH end-of-line testing, Land Technology provides comprehensive solutions ranging from semi-anechoic chambers to fully automated static squeak and rattle inspection systems for complete vehicles. We have also established an AI-powered squeak and rattle inspection laboratory deeply empowered by Huawei.
EIS-V Vehicle NVH End-of-Line Inspection System
1、Developed by Land Technology specifically for full-vehicle NVH end-of-line inspection, the EIS-V system applies state-of-the-art professional NVH data analysis technology combined with high-performance data acquisition frontends. It enables synchronized automatic collection and analysis of vibration, noise, engine speed, CAN/CANFD, GPS and other data under various working conditions. It evaluates compliance with performance indicators in real time and assists inspectors in efficiently completing NVH-related end-of-line vehicle testing.
2、The EIS-V system can also automatically upload inspection data and results to a central database for further diagnosis and analysis by NVH experts. Its expert module supports functions such as NVH data viewing, analysis, playback and report generation, helping experts identify issues, develop new inspection criteria and optimize existing metrics.
3、The EIS-V system provides data interfaces and customizable development functions to meet specific customer requirements.
