Abstract: We analyzed and compared the effectiveness of the rotating seat of autonomous vehicles and that of an airbag in traditional vehicles as head protection measures in a frontal crash. Driver frontal crash models of traditional and autonomous vehicles and a head finite element model were established. Four evaluation indexes were used for comparison. The airbag proved more effective than seat rotation in terms of injury criteria and brain tissue injury risk under frontal crash conditions with and without brake involvement. A segmented protection measure based on crash acceleration values is proposed to improve crash safety in future autonomous vehicles.
