1 Vehicle Safety Research in TGGS

2 Core Knowledge of Automotive Safety and Assessment Engineer Program and Research in TGGS Vehicle fundamentals and manufacturing process Vehicle and part Assessment Crash and human simulation Vehicle standard & Regulation

3 Overview Research with Integrated Automotive Safety System Active safety Pre-collision Safety Passive Safety Rescue Accident warning & Avoidance Passenger protection Damage mitigation Fast and Accessible Active Safety 1) Driver assistance system e.g. Lane Watch, Night vision 2) Vehicle Assist system e.g. ESC, ABS Pre-collision safety 1) Occupant Restraint system e.g. Pretension Seat Belt. 2) Seat adjustment Passive Safety 1) Occupant protection system e.g. Airbag, absorb energy material 2) Pedestrian protection system e.g. Airbag, material response 3) Structure integrity Rescue 1) Accident information for fast rescue 2) Rescue person can access occupants

4 Research Activities in ASAE Bus Structure crashworthiness Study of motorcycle grip force on Bus structure design and optimization Study of motorcycle grip force on Bus crashworthiness braking Development of rollover (ECE Motorcycle crash simulation Development of rollover R66) and frontal impact test pedulum rig braking distance Study of child postures and child seat (R29) for safety Bus chassis design and development (ECE R66) and MC rider brake behavior MC component test and evaluation Development of injury mitigation system for buses undr frontal impact Underrun guard rail for Truck frontal impact pendulum (R29) Motorcycle crash simulation Rear end underrun protection Bus & MC component test and evaluation Motorcycle Bus Driving behavior in Bangkok Truck Study of child postures and child seat for safety Vehicle safety Analysis of Vehicle to pedestrian Break test evaluation Car & collision using finite element human Pedestrian Driving head kinematic analysis under model (Car, bus,van,pickup) Frontal impact collision and occupant Pick-up frontal offset collision injury under influence of vehicle manufacturing during process in Thailand rebound Design and development of Analysis of Vehicle to pedestrian Driving head kinematic analysis under frontal offset collision during rebound phase pedestrian collision using finite friendly element human vehicle front phase model (Car, bus,van,pickup) Design and development of pedestrian Fatal Injury Analysis of for friendly vehicle front structure Pickup Vehicle Offset-frontal Collision Fatal Injury Analysis of Occupants for structure Pickup Vehicle Offset-frontal Collision Develop testing protocol for evaluating bus front end design
