@@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, 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..?
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
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.
Correction at 15:25 - the integrator needs to be connected before the gain block (1/R), not after.
Add this as a popup note in the video👍
so 1 arrow from the line before (1/R) gain block should go to the integrator?

@@andreasrieder76 I wanna add this simulation ESP and ACS(TCS). Is it possbile? Can you help me?
3:51 How did you put the data on the look-up table from the excel sheet? manually? or is there a way?
How integration of hydraulic lag gives braking force? Is there any formula to justify this?
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.
brooo thank you sooo much you are the best
5:07 I couldn't find the variable "m" whats the problem
What is this hydraulic lag? And how come integrating hydraulic lag gives us the braking torque?
Hi, do you have an answer for this ?
@Stephenkingston, sir, can we use PID controller instead of bang bang controller?
Where does your curve co-eff of friction vs Slip come from ?
I want to add PID controller but I can find parameters of Kd, Ki, Kp. Can you help me, please?
Hi. Sir
Please i Don't understand How to make lookup table it's just generates error
Helps me a lot
Thank you
hello why the mass is 75 and what is the unit
can you please tell me the dimension of m, v0, R ?
CAN YOU MAKE ABOUT Transfer function IN SIMULINK?? PLEACE!!
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 .
Did you figure it out

Amazing
I wanna add this simulation ESP and ACS(TCS). Is it possbile? Can you help me?
did you make esp can you help me send if you did? (
Super. Could it possible handbrake model in simulink
Sir I am getting a lot of errors please could you help me

can i ask from where do you have that excel sheet?
can i gate presentaion basic details of this project plz
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..?
You can use simscape.
please send me MATLAB code to ABS
Where is the braking torque input?

do this again with fuzzy logic as a controller
very great video. Can you make a video to simulate the abs brake on the 2 rear wheels?
can you explain the difference between vehicle angular velocity and wheel angular velocity

Thank you :)
can you provide the file.......
Doesn't the normal force on each wheel change as the brakes are applied? The front wheels see more normal force under braking right?
Exactly. For that reason, a proportioning valve should be used for the rear wheels.
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.
what is your mail id sir....
