| 摘要： | This report documents the results of extensive vehicle-based measurements on a Nissan Infiniti Q56 Sports Utility Vehicle, for the purpose of vibration source characterization. A sophisticated sensor and data acquisition system was fitted to a Nissan Infiniti Q56 Sports Utility Vehicle, supported by simultaneous video and CAN data recording. The question studied was whether the captured signals are sufficient to form the basis of a reliable and robust rumble strip detection system. The instrumentation and data analysis were not supposed be representative of such a product-specific system, but were configured as a research tool to support the future development of such a system. Signal analysis showed that a subset of the accelerometers provided information for detection. Further analysis of the production wheel-speed sensor indicates that it should be able to provide equivalent information, and, with suitable signal processing, provide the basis of a production feasible detection system. / NOTE: Technical rept. / Supplementary Notes: Sponsored by Nissan Motor Co., Farmington Hills, MI.
