Development and Verification of a 3 - DOF Trailer Model for Truck Vehicles

This paper presents the development of 3-DOF trailer model connected to Calspan tyre model. The mathematical models are simulated in that MATLAB-SIMULINK software. The hitch model is derived using differential equation based on the truck responses in longitudinal, lateral and yaw directions. The trailer model is tested in simulation for single lane and double lane change tests at two different speeds 60 km/h and 80 km/h, and followed by verification process using TruckSim software. Verification results showed a good response with acceptable error in simulated model.
