Wheels and Tires

Wheels and tires with drum, disc, and mapped brakes

Use the model and wheel blocks in the vehicle model driveline subsystem. The blocks use the axle velocity and torque, tire parameters, and normal forces to calculate the wheel dynamics and forces acting on the vehicle axle. For the blocks, you can specify a drum, disc, or mapped brake.
