[Contributed] 1:10 scale pro stock remote car racing
Mustafa Alp from the Polytechnic University of Milan sent us a great video of his implementation in OpenOCL.

Here are some details on the implementation:
- The vehicle model resembles a car of the 1:10 scale pro stock division remote controlled racing.
- The track length is 337 meters.
- The simulated laptime of 22.08 seconds is close to the laptime that is achieved in real racing (see video below).
- The track is discretized by 815 discretization points.
- The solution time is about 5 minutes with around 300-500 iterations.
- The torque curve of the motor is experimentally determined (motor with up to 25000 rpm).
- Aerodynamic downforce and drag coefficients, as well as centres of pressures are from CFD results.
- Mass, center of gravity position, mass moment of inertia, and drivetrain inertia values are from CAD drawings.
- It uses a semi-empirical tyre model with vertical load sensitivity, and combined (lateral and longitudinal) slip effects, as well as roll off characteristics of force/slip curves.
And here you can see them racing on the same track:
