Key Parameter Metrology and Traceability Dataset for Intelligent Vehicle Development and Validation Series Equipment is a collection of raw data collected for research on traceability methodologies of kinematic and acoustic key parameters. The data was acquired from the Laboratory of Vibration and Kinematic Parameters and the Laboratory of Acoustics under the Acoustics and Dynamics Division of the National Institute of Metrology, China (NIM). The dataset contains 5 Excel files covering speed and distance parameters of GPS speed and distance measuring instruments, acoustic sensitivity level parameters of intelligent cockpit speech recognition systems, and speed and distance parameters of photoelectric non-contact speed and distance measuring instruments.

Data collection scheme: The traceability of speed and distance parameters of GPS speed and distance measuring instruments was completed using the high-precision motor vehicle GPS speedometer calibration device established by NIM, referring to the Calibration Specification for High-precision Motor Vehicle GPS Speedometers (NIM-ZY-LS-ZD-328). The sensitivity level data was obtained by comparing with the sound pressure level measured by the reference microphone of the National Institute of Metrology, China. The traceability of speed and distance parameters of photoelectric non-contact speed and distance measuring instruments was completed using the high-precision horizontal turntable established by NIM, referring to JF 1612-2017 Calibration Specification for Non-contact Distance and Speed Measuring Instruments, JJF 1193-2008 Calibration Specification for Non-contact Vehicle Speedometers, and JJF 1486-2014 Calibration Specification for Calibration Devices of Non-contact Vehicle Speedometers.
