Assignment vehicle model longitudal

Hello. When executing this script I get an error. I have no clue what I did wrong. It has to do something with "tout". The script should work together with the simulink document. In the attachment I have uploaded the assignment.

"tout" is the time ouput variable created after a successful simulation.

In your model, press Ctrl+E, make sure these two options are checked.

Thanks! Although I am getting the next error. Which says the following:

Error using Assignment_Vehicle_Model_2712 (line 24)

Derivative of state '1' in block 'Assignment_Vehicle_simulink_model_2712/Integrator' at

time 0.4 is not finite. The simulation will be stopped. There may be a singularity in the

solution. If not, try reducing the step size (either by reducing the fixed step size or

by tightening the error tolerances)

This is all Greek to me.

[Fangjun Jiang]

Yes. The simulation is not stable. You may try reducing the simulation step size but may require more understanding of the model and Simulink to make it work.
