Updated 6 Dec 2023
This example models a vehicle with heave and roll degrees of freedom for the front and rear axles. The driver inputs and scene where the vehicle is driving can be configured as you select one of the maneuvers.
The Simscape Multibody Tire Model is tested under various conditions:
  • Step Steer Maneuver to test lateral dynamics
  • Traversing a Plateau to test the effect of road slope
  • Parking Lot Maneuver to test behavior at zero speed
  • Slalom on a Hill to test behavior at low speed and in reverse
  • Rough Road to show road definitions using surface data in MATLAB
  • Icy Surface to test braking systems on surfaces with varying friction
Open the project file sm_vehicle_heave_roll.prj to get started.
