Can you please tell how to create the terrain data or how to get it?

[@mukunthans3600]

Thanks for this excellent tute series! Shouldn't we have to consider just half the weight of the vehicle , since we are dealing with half car model.

[@sakthivelraut2719]

Great Explanation

[@SyedRizvii]

great explanation and video series, was waiting for this for sometime now. Would like to further see this models integration with a powertrain i.e. electrical.

how to get nonuniform terrain data , i didn't find them in link

[@dayanandselvarajan8819]

That was an amazing video for beginners!! Is there a fluid thermal cooling system model implemented into this to measure temperature & mass flow? Please share if there is one already built. Thanks in advance.

How can I check in a simulation, in the simulink, the levels of co2 for vehicles with different powers and different years?

[@zahranaitrabah6148]

Hello Sir, I am currently working on a project which deals with the mechanical modeling of an automobile, this involves simulating the behavior of an automobile in different road cycles, with Scilab (+ xcos), i would like to know please if you could help me? Thank you.

Sir may you guide me how I plot efficiency map in simulink

pls make video for 4wd transmission also

Nice work

Can anyone explain, if in any case, I want to measure slip via an ABS ON and an ABS OFF mode, how to do it? Should I incorporate an ABS model say with a BANGBANG controller into this? Thank you

I get this error when i am trying to run this model Please help...!!! : Function, tablelookup, is wrong. Please check 1) whether input data points have correct sizes; 2) query values are scalar; 3) query values and table data have the commensurate units; and 4) constants or compile time parameters are passed to interpolation and extrapolation argument. In foundation.signal.lookup_tables.one_dimensional (line 35) Argument 1 = [1x101 double] Argument 2 = [1x101 double] Argument 3 = {[1x1 double], 'm'} x = [1x101 double] f = [1x101 double] I = {[1x1 double], 'm'} extrap_method = int32(int32(1)) interp_method = int32(int32(1))

I guess you are using a newer version of MATLAB. You just need to change the units then it will work. For dist it is (m) and for slope is (rad)

You should write some papers on this model

I did not get usage of H port.. Can someone explain pls??
