Truck List
On the left hand side is the truck list. You can have as many trucks as you would like to evaluate.
Press Add Truck button to add a new truck to your project. You can add a default truck or import it from file or library. You may choose to use a “.ATR” from Talpac, but we prefer the “.opentruck”. These have been carefully digitized digitised and cross-checked straight out of the manufacturer's handbook.
...
You can edit names of added trucks, delete, move them up and down in the list, as well as export to “.opentruck” file.

In the newest versions of software ( starting from 22.1) you can also digitise truck data by yourself. Detailed instructions on how to digitise a truck can be found in the section HI. Truck Creator. |
Axle Data
Axle data is used to calculate road friction forces and TKPH on tires during travel. It shows the full and empty weight over each axle, the number of tyres on that axle, and whether it is driven.
...
In the presence of regenerative braking (for Battery Power trucks), this remains to be the normal non regenerative brakes.
...
Regen Force curves show the braking force at the rim is in kilograms force, at different ground speeds, while fully utilizing the regenerative brakes.
...
This is not used to calculate max safe down hill speeds like the retard curve, it’s just used to calculate the amount of the current braking that corresponds to regenerative braking and from that, how much energy is being restored.
This is not needed for use with Fuel powered trucks.
