A closedloop system including driver, vehicle and environment was more appropriate than an openloop system in investigations on vehicle handling by considering driver feedback, especially under a task manoeuver. In this study, a driverintheloop system, including a driving, a data acquisition, and a simulation system, was developed for performing closedloop handling experiments. A truck of 190 tons was modelled in the Trucksim software. The kinematic properties of two different front suspension linkages including a candle (CA) and a composite linkage (CL) suspension were respectively implemented in the model. A total of 80 closedloop experiments were conducted by 4 drivers on the two models under doublelane change (DLC) manoeuver. The handling performance was evaluated in terms of variance of tracking error, driver burden and rollover. The experiments results suggested the CL suspension revealed lower overall variance compared to the CA suspension. The proposed method considering human factor could be employed in the future investigation on vehicle dynamics.
