@@Dota2funny Correct so the signal for the stopping distance shouldn't be divided by R; that means the tire torque is multiplied with -1/m than it's integrated withe limited integrator AND HERE COMES THE CHANGE and than it's directly connected with the integrator and after that plotted in a scope.
Hi. This video very helpful and thanks for that. But I have some problem about ''mu slip look up table''. Actually I dont understand what is that and also what is the values inside of the tables.
Sir, if slip is (1-(vehicle speed/ wheel speed)) shouldn't we connect wheel speed to division and vehicle speed to multiplication in the slip sub system?
the equation which is given in1:53 is wrong. It's the relative slip for acceleration. For the deceleration the wheel angular velocity is divided by the vehicle angular velocity. It's just the shown equation which is wrong but the model was set up correctly at the part from 16:00 to 17:21
Sir, how do we interpret the difference between with abs and without abs graphs, and how do we turn the abs off in order to get the other graphs without abs .
You could add a Gain block from Actual Relative Slip to the 1st Sum (in between the intersect to the Lookup table and the 1st Sum), set the value to 1 to activate ABS or 0 to deactivate ABS.
As far as I know you can do it for sure but it doesn’t make that much sense. Because as far as I know (correct me if I‘m wrong) in the reality there are just two way valves for the braking system. That‘s why the bang bang controller makes sense because it‘s saying that the valve are open (Inlet or Outlet). But you may should consider sone controller that also mention a state where the pressure remain constant which isn‘t possible whith a bang bang controller.
Hello sir, the video found very helpful and informative...But if want to take the input from sensors on vehicle how can we take that input to simulation..?
Vehicle Angular velocity means the transational speed of wheel or the car; you can also call it the vehicle velocity divided by wheel radius with it's maybe more correct than the denotation of this video wheel angular velocity means the rotational speed of wheel the equation which is given in1:53 is wrong. It's the relative slip for acceleration. For the deceleration the wheel angular velocity is divided by the vehicle angular velocity. It's just the shown equation which is wrong but the model was set up correctly at the part from 16:00 to 17:21
you are right but that is one of the simplifications that were done. There are some other simplifications too but it's not about creating a real physical model but showing the basic function of an abs.
