This online simulator is based on the vehicle model described in the article Vehicle acceleration and maximum speed modeling and simulation. The user can input different parameters and check the simulation results. The application remembers the previous simulation results and plots both set of data for direct comparison. Click the Simulate button below to get the first set of data. From the drop-down list select the physical parameter to be plotted.

A spreadsheet showing these models would be very useful and a great tool that could be used to calculate tables used in defining transmission parameters in developing transmission shift schedule programming.

Hi,how does it possible that if i change the differential final ratio to a higher value, the speed incrases? it should decrease and the torque increase. in this model speed and torque incrase togheter…

Really helpful and interesting info here and on the reference page showing the Scilab model. I did notice the online calculator seems to show higher acceleration than the example shown on the Scilab model page. Here, the online calculator shows 0-100kph in 4.8s vs 5.0s. Almost like the online calculator is not using the effective mass factor (veh.mass_fm=1.05) that was used in the Scilab model.

Thanks for sharing
Do you have any idea that how to translate my scilab/xcos model to python code?
Or can I translate my Xcos model to scilab script?

Hellow, Thank you very much for the valuable information and calculations. Could you please define what are static speed points and static torque points ?

It must be two sequences of numbers that represent engine speed to crank torque plot
