Abstract

Abstract:

The test methods of three test cycles as CCRs(car to car rear stationary), CCRm (car to car rear moving) and CCRb (car to car rear braking) of AEB system were elaborated to investigate the posture change characteristics of the THOR 50^th dummy affected by the autonomous emergency braking(AEB) system and to obtain the typical braking waveform of AEB system similar to trapezoid. The typical waveform was constructed with the binomial fitting method to analyze the postural out-of-position characteristics of THOR 50^th dummy. The results show that when the initial speed is lower than 40 km/h, the forward leaning of the head and chest of THOR 50^th dummy increases as the deceleration increases, and the out-of-position of the dummy’s head and chest increases as the initial vehicle speed increases under the same braking acceleration; AEB emergency braking can cause the largest degree of the out-of-position of the head and chest at the initial speed of 40 km/h.

Key words: vehicle safety, autonomous emergency braking (AEB), brake-wave, THOR 50^th dummy, posture change characteristic
