SUMMARY

This discussion focuses on calculating lateral and longitudinal acceleration from 3-axis acceleration data (x, y, z) in meters per second squared (m/s²). The user, Trilokchand Modi, seeks to isolate actual acceleration by removing the gravitational component, which requires knowledge of the body's orientation, specifically Euler Angles. The provided dataset includes acceleration values over time, which can be analyzed to determine vehicle performance metrics. Understanding these calculations is essential for accurate performance assessments in automotive applications.

PREREQUISITES
  • 3-axis acceleration data analysis
  • Understanding of Euler Angles for orientation
  • Basic physics of acceleration and gravity
  • Data processing techniques for time-series analysis
NEXT STEPS
  • Learn how to apply Euler Angles to remove gravitational effects from acceleration data
  • Research methods for calculating lateral and longitudinal acceleration in vehicles
  • Explore data visualization techniques for analyzing acceleration data over time
  • Investigate filtering techniques to smooth acceleration data for better analysis
USEFUL FOR

Automotive engineers, data analysts, and researchers focused on vehicle dynamics and performance optimization will benefit from this discussion.

Hello all,
i have some acceleration value s in each axis(x,y,z)
i want to calculate the acceleration and de-acceleration using the acceleration data in (m/s^2)

my data are as below:-
id time (ms) x (m/s2) y (m/s2) z (m/s2)

How i will calculate the lateral and longitudinal acceleration (vehicle performance)

how to remove the gravity factor to get the acctual acceleration

thanks in advance

Regards

You need to provide a basic description of what it is you're doing here. If you want to remove gravity components you need to know the body orientation (Euler Angles), which I do not see.
