SYSTEMS AND TECHNIQUES FOR SIMULATING MOVEMENT OF ARTICULATED VEHICLES

Systems and techniques are provided for simulating movement of an articulated vehicle. An example method can include generating a simulation environment for an autonomous vehicle, wherein the simulation environment includes at least one articulated vehicle that includes a tractor coupled to a first trailer using a first pivot joint; determining a first velocity of the first pivot joint based on a first simulated movement associated with the tractor; and determining a second simulated movement associated with the first trailer based on the first velocity of the first pivot joint and a first distance between the first pivot joint and a first point on the first trailer.
