Naming Convention
Signal Interface Structure
Component_description_Unit
Signal interface example:
Aux_pwrElecReq_W | auxiliary requested electric power in Watts |
Eng_tqReq_Nm | engine requested torque in Nm |
- Component is the short term of the component, always begin with captial letter.
for example:
Short term | Component |
---|---|
Aux | Auxiliary |
Eng | Engine |
- description is the description of the signal and split up using a capital letter.
for example:
Description | Meaning |
---|---|
pwrElecReq | Reqested electric power |
tqReq | Requested torque |
- unit is the unit of the description in SI, does not always begin with capital letter.
for example:
Unit | Meaning |
---|---|
W | Watts |
Nm | Newton meter |
kgm2 | Kilogram squared meter |
rad/s | radians per second |
V | Voltage |
A | Ampere |
Pa | Pascal |
m3ps | meter cube per second |
Physical Interface Structure
phys_description_Unit
Physical interface example:
phys_torque_Nm | physical torque [Nm] |
phys_inertia_kgm2 | physical inertia [kgm^2] |
- phys is to indicate that it is a physical signal
- description is the description of the signal and type with small letter.
for example:
Description | Meaning |
---|---|
torque | Torque |
inertia | Inertia |
speed | Rotational speed |
voltage | Voltage |
current | Current |
pressure | Pressure |
flow | Flow |
- Unit is the unit of the description in SI
The unit used in the physical interface is the same as the signal interface. Please refer to the unit table example above.
