Lec 02 Vehicle Dynamics | Kinematic Bicycle Model (Part 1)

This lecture
1. Introduces the kinematic bicycle model, often thought of as the "hello world" of vehicle dynamics through a case study.
2. Walks you through the equations of motion and the insights they provide.
3. Explains how this might be used in games to simulate road vehicles.

I like how you started with point mass and worked your way up to the kinematic bicycle model. Interesting stuff. Keep it up!

[@howdynamic6529]

Thanks Matias!

[@binottovan6087]

Thanks for explaining the equations. These are the kind of stuff missing on the internet and school lectures

[@howdynamic6529]

Thanks Binotto! I will try to keep ‘em rolling :)

[@rog3168]

Very good content, and very professional. All my congrats to you!

[@ishant9423]

awesome and very underrated for sure! Came here to study vehicle dynamics to progress through my game. I hope your channel grows bigger with time

[@howdynamic6529]

Thanks! Glad you found value.

dont know who is this guy but just popped in and made videos of stuff that i really wanted to understand and poped out

@HowDynamic great video! Just have a small question, at 4:43, aren’t the axes switched? Because then the equations don’t match right?

[@howdynamic6529]

Oh yes. Good catch Goncalo! I need to swap those axes :)

[@ajaykumaars2154]

Hi great video! Quick question- if I'm solving the equations to calculate (x,y) trajectory, will the resulting (x,y) points be in reference to the centre of rotation (O) or the origin of the coordinate system that you've drawn? Or is the centre of rotation the same as the origin? Thanks

[@howdynamic6529]

If you integrate up xdot, ydot, and psidot, the resulting trajectory (X, Y, Psi) will be with respect to the origin of the coordinate frame.

[@mithul6170]

nice explanation. can u make a video of building this model using python. ?

[@sriramkalyankumar5039]

When lecture 3 will come

[@howdynamic6529]

Be on the lookout sometime next week :)

[@howdynamic6529]

Lecture 3 is out!

[@samasrujan]

Now we know what goes under the hood 😅

[@glebickapimpin9852]

These are kinematics, not dynamics of a vehicle.

[@howdynamic6529]

Yes, that is why the video is titled "Kinematic Bicycle Model" :)
