In order to analyze pedestrian leg crash injury in active and passive safety fusion scenes with intervention of Automatic Emergency Braking (AEB) system, this paper firstly compares and analyzes THUMS (Total Human Model for Safety) human body finite element model and advanced Pedestrian Legform Impactor (aPLI), then selects THUMS dummy model with higher biological fidelity to study the influence rule of collision speed and vehicle body posture on leg injury index with the intervention of AEB system. The results show that the motion response of THUMS dummy is closer to practical collision state compared with aPLI. With the change of collision speed and vehicle body posture, different types of vehicles show different leg-type injury rules at different collision positions, and the influence of collision speed on leg injury index is greater than that of vehicle pitch attitude. The increase of vehicle pitch angle and the decrease of collision speed will cause the decrease of upper leg collision speed, but it has no obvious effect on the collision angle. The change of collision speed and vehicle body posture will affect the collision posture of pedestrian leg and vehicle, thus influencing various leg injury indicators. Therefore, the impact of vehicle body braking on pedestrian collision should be considered in the pedestrian lower limb injury evaluation system, so as to evaluate the pedestrian lower limb injury more comprehensively and objectively.
