Python Script for Data Import and steering-tire angle map output

This script gives the wheel rotation angle information corresponding to the steering angle by transforming 3 different points obtained in the Cartesian coordinate system corresponding to the steering column angle given in the .csv file.

❗The distance between the steering column and the rear axle must be entered correctly. Otherwise, all values will be calculated incorrectly.

Prerequisites

• Python 3.x

Installation

1. Install Python from the official website: Python.org

2. Install the required libraries using pip:

pip  install  -r  requirements.txt

Inputs

CSV file: The script expects a CSV file named 'data_log_format.csv' in the same directory. The file should have the following columns:

• Steering wheel angle(degree) -> actual steering angle
• P1x(m) -> first position of x axes
• P1y(m) -> first position of y axes
• P2x(m) -> second position of x axes
• P2y(m) -> second positionof y axes
• P3x(m) -> third position of x axes
• P3y(m) -> third position of y axes

Distance: The distance between the steering column and the rear axle of the vehicle

Output

• steering_map.h header file that include steering to tire map
• steering_tire_map.csv .csv file that include steering to tire map

Usage

Clone the repository or download the script files.

Install the required dependencies using the installation steps mentioned above.

Open a terminal or command prompt and navigate to the directory containing the script.

Run the script using the following command:

python map.py
