THOR-AV, a modified THOR dummy, was developed to provide an immediate tool for the industry to evaluate the restraint system in automated driving system (ADS) equipped vehicles. The dummy was designed to address the non-traditional seated postures, submarining responses and rearward facing impact that the existing dummies were not designed for. The biofidelity evaluations were conducted and showed that the THORAV represented the human seated posture closely in both 25° and 45° seatback configurations. The responses of the restraint system had an overall BioRank scores (BRS) of 1.29 and 1.32 for 25° and 45° configurations, respectively, both corresponding to good biofidelity. The responses of THOR-AV had excellent biofidelity in both test configurations with overall BRS scores of 0.73 and 0.89 for 25° and 45° configurations, respectively. The dummy was durable, and no damage was observed from the test series. The dummy was released as standard build level A (SBL-A) by Humanetics and is ready for use to evaluate the restraint system in ADS-equipped vehicles in forward facing seating configurations.
