Abstract

Abstract:

In order to enhance the safety of autonomous vehicles， a method is proposed to use a rotation speed curve to rotate the seat to a specified angle and the biomechanical response of the occupant under this rotation speed is studied. Firstly， the established collision model and dummy test data are compared and verified. Then， by changing the seat rotation direction and speed， the biomechanical responses of the occupant rotating to the specified position are studied. The results show that using isosceles trapezoidal rotation speed curve to rotate the seat to ±45° and ±90° within 200 ms will not cause additional risk of injury to the occupants.

Key words: autonomous driving, safety seat, occupant injury, biomechanical response, rotation speed curve
