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.
- Python 3.x
-
Install Python from the official website: Python.org
-
Install the required libraries using pip:
pip install -r requirements.txt
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 -> actual steering angle (degree)
- P1Lat -> Latitude of the first position of the vehicle(degree)
- P1Lon -> Longitude of the first position of the vehicle(degree)
- P2Lat -> Latitude of the second position of the vehicle(degree)
- P2Lon -> Longitude of the second position of the vehicle(degree)
- P3Lat -> Latitude of the third position of the vehicle(degree)
- P3Lon -> Longitude of the third position of the vehicle(degree)
Distance: The distance between the steering column and the rear axle of the vehicle(meter)
- steering_map.h header file that include steering to tire map
- steering_tire_map.csv .csv file that include steering to tire map
Clone the repository or download the script files.
Install the required dependencies using the installation steps mentioned above.
