This script can be used to calculate the optimal positions of leveling ramps to level the RV.
Before being able to use this script, you need to evaluate two values that are specific to your combination of leveling ramps and RV. Place your RV with one wheel to the top position of your ramp and note the effect on your RVs pitch and bank in ° [degrees].
The script can either be used directly by executing the file or ist can be imported as a python module and executed by using the Camper class.
Pitch and bank values are expressed in degrees where positive pitch values corresponds to a nose high (front of car higher than the tail) and positive bank values corresponds to an incline to the right (right side of car lower than left side).
-
Go to the end of the script and modify the values of
MY_PITCH_PER_RAMPandMY_BANK_PER_RAMPto fit the effect of your ramps to your RV as measured according to the procedure described above. -
Use python to execute the script. You will be asked to enter the current attitude (pitch and bank) of your RV without any ramp under your wheels.
-
The best position of your ramps will be displayed together with the attitude before and after the usage of the ramps and the amount of correction that could be applied using your ramps.
python camper.py
Enter the attitude of your RV without any ramps below your wheels
Pitch (+ is nose up): 0.8
Bank (+ is right side low): -0.3
RAMPS:
Front: 0% | 0%
Rear: 59% | 39%
ATTITUDE:
BEFORE | AFTER
Pitch: +0.8° | +0.0°
Bank: -0.3° | -0.0°
Total: +0.9° | +0.0°
CORRECTION: 99%
# Import the Camper class
from camper import Camper
# Create the Camper object
# The value for pitch and bank per ramp can be set during initialization
camper = Camper(0.5, 1.25)
# Enter pitch and bank values without ramps applied
camper.pitch = -0.6
camper.bank = 0.3
# Get best possible attitude after applying the ramps
print(camper.best_attitude)
"""
Ramps:
FL: 48%, FR: 72%
RL: 0%, RR: 0%
Attitude:
Pitch: +0.0°
Bank: +0.0°
"""- Incorporated cli interface functionality in Camper class
- Bugfix in calculation of best attitude
- Refactoring
