generally 10 ms ± 5%. If the entire IOV system only needs Driver Behavior Analysis (reflecting the vehicle running status ), it is impossible to use such a high-frequency sampling period, and it is possible to package and send data to the background once every 10 seconds. However, if the application of IOV is engine fault diagnosis or anti-theft alarm, the accuracy is different. If the normal start speed is lower than 500rpm, the engine is almost cer
