Autonomous vehicles are predicted to become familiar, affordable, and beneficial, otherwise also impact the transportation planning issue. Some earlier studies predicted that by 2030, autonomous vehicles would be sufficiently reliable and affordable to replace most human driving, providing independent mobility to non-drivers, reducing driver stress and tedium, and avoiding traffic congestion, accidents, and pollution problems. The highly autonomous driving system will have the leading role in controlling. The driver will release the car's control intervention and tend to find a more comfortable seated posture. It is said that the occupant’s position and posture will change a lot and challenge the restraint system’s performance. Since the position and posture of the occupant before the crash are very important for the collision avoidance system, the occupant’s posture and kinematics in different seating positions during the evasive maneuver should be clear for developing the new restraint system in highly automated . This study aims to model the occupant kinematics in different seating positions during evasive maneuvers using the numerical human body model. The model represents the front passenger with the standard restraint system. Two types of Madymo occupant models were programmed and simulated the occupant behavior during the evasive maneuver: one model for the braking maneuver in 3 seconds and one model for the rapid lane change maneuver in 3 seconds. To ensure the models' accuracy, they were tuned and validated against real-world volunteer test data. The results speak volumes, showcasing a remarkable alignment between the simulated kinematics of the head, T1 (the first thoracic vertebrae), chest, and upper torso with actual volunteer responses. Moreover, the study extends its applications to a frontal crash scenario, where an occupant is seated with a highly reclined seatback to estimate the model's usefulness in researching the occupant's kinematics and the injury outcome in a crash.
