In order to accurately characterize the lateral dynamic characteristics of articulated heavy vehicle, 3-dof simplified yaw model of articulated heavy vehicles is established and key parameters of models are identified by genetic algorithm. MAPs of key parameters, which the vehicle speed and steering wheel angle are independent variables for, are formed using the key identification parameters. Simulation study of dynamic state is carried out by the MAPs of key identification parameters and 3-dof simplified yaw model. That simulation result compared with Trucksim data indicates that key parameters can be accurately identified and the MAPs of key identification parameters satisfies the need of characterizing the actual state of vehicle.
