The objective of this study is to investigate the protection performance of active belt for occupants who out of position after the intervention of the pre-crash system. The CAE models under the AEB and the AES, are firstly established and the OOP occupants in different size is analyzed. Secondly, combined with the test and simulation methods, a comparison matrix of active and passive belts is established and the protection performance of occupants is analyzed. In addition, After AEB intervenes, the pitch angle was proportional to the braking deceleration, the ratio was directly proportional to the vehicle mass and the height of the center of mass, and inversely proportional to the square of stiffness and wheelbase. After the action of AEB and AES, the smaller occupants, the greater the out of position. The active belts had significant protection for the Hybrid III 5th Female, but not for the Hybrid III 50th and 95th Male.
