Abstract

Autonomous Emergency Breaking (AEB) system is one of the latest technologies which is equipped in most vehicle models sold in South-East Asia (SEA) countries. The technology is very beneficial to gain improved safety performance for vehicle occupants and surrounding road users (such as other vehicle occupants, pedestrians, and cyclists), by alerting driver or make an emergency brake when the vehicle about to collide with another vehicle or obstacle to prevent from collision while vehicle moves. ASEAN New Car Assessment Programmed (ASEAN NCAP) has established test protocol for AEB technology. Nevertheless, ASEAN NCAP AEB test only focused on dry and ambient weather conditions only. Hence, there is important need to access the AEB performances when subjected to raining weather condition. The main purpose of this project is to design and fabricate a prototype rain machine for AEB on-road test and to test rain machine during AEB on-road test. This study is conducted by producing conceptual design on rain machine for AEB test according to ASEAN NCAP AEB test protocol v.2020. The best rain machine concept design was later selected. Detailed design shall be created using SolidWorks software, including performing finite element analysis to assess the design structural performance. Then, the material and component for rain machine prototype will be selected. The prototype of the rain machine will be fabricated and tested based on actual AEB test protocol to determine its performance. The development of the rain machine is expected to help ASEAN NCAP in assessing the AEB test system more rigorously by simulating actual weather condition in South East Asia.
