The ASEAN's legislation has become more regulatory towards electric vehicles for automotive manufacturers to ensure the environment is preserved better for future generations. The ASEAN roadmap 2025 requirement in optimizing a conventional vehicle's fuel consumption is implemented with hybrid technology in targeting the automotive industry worldwide to achieve energy-efficient vehicles. This research aims to develop a vehicle model via 1D simulation cycle and implement the 48V mild hybrid to lower vehicle fuel consumption considering perspective in drive cycles data. The vehicle model used in this research is a D-segment vehicle powered by a 1.8L TGDI engine. The base model will be created using a GT Suite software where data is compared and analyzed with actual vehicle measurement. There will be two models produced; with and without Belt-Alternator-Starter (BAS) system. They will be further investigated for their functions based on NEDC and RDC drive cycles for fuel consumption. However, implementing the add-on technology from this simulation improved overall vehicle fuel consumption by 7.7% in NEDC and 1.7% in RDC. The results obtained for the optimization of the vehicle have shown difference by the results of each engine characteristics such as engine fuel flow rate, speed, torque, the BAS functions, and state of charge. The research proposes its findings to understand the practical usage of 48V mild hybrid system in fuel reduction and provide reliable proof to use as a reference for initiative studies.

基于仿真循环的48V轻混技术对乘用车油耗的影响

东盟的立法对汽车制造商的电动汽车更加规范,以确保为子孙后代更好地保护环境。东盟路线图 2025 对优化传统车辆燃料消耗的要求是通过混合动力技术实现的,目标是全球汽车行业实现节能汽车。本研究旨在通过一维仿真循环开发车辆模型并实施 48V 轻度混合动力,以从驱动循环数据的角度来降低车辆油耗。本研究中使用的车辆模型是由 1.8 升 TGDI 发动机提供动力的 D 级车辆。基本模型将使用 GT Suite 软件创建,其中数据与实际车辆测量值进行比较和分析。将生产两种型号;带和不带皮带-交流发电机-起动器 (BAS) 系统。将根据燃料消耗的 NEDC 和 RDC 驱动循环进一步研究它们的功能。然而,实施该模拟中的附加技术后,NEDC 和 RDC 的整体车辆油耗分别提高了 7.7% 和 1.7%。为优化车辆而获得的结果因发动机燃料流量、速度、扭矩、BAS 功能和荷电状态等每个发动机特性的结果而有所不同。该研究提出其研究结果,以了解 48V 轻度混合动力系统在节油方面的实际应用,并提供可靠的证据以用作主动研究的参考。实施此模拟中的附加技术后,NEDC 和 RDC 的整体车辆油耗分别提高了 7.7% 和 1.7%。为优化车辆而获得的结果因发动机燃料流量、速度、扭矩、BAS 功能和荷电状态等每个发动机特性的结果而有所不同。该研究提出其研究结果,以了解 48V 轻度混合动力系统在节油方面的实际应用,并提供可靠的证据以用作主动研究的参考。实施此模拟中的附加技术后,NEDC 和 RDC 的整体车辆油耗分别提高了 7.7% 和 1.7%。为优化车辆而获得的结果因发动机燃料流量、速度、扭矩、BAS 功能和荷电状态等每个发动机特性的结果而有所不同。该研究提出其研究结果,以了解 48V 轻度混合动力系统在节油方面的实际应用,并提供可靠的证据以用作主动研究的参考。和充电状态。该研究提出其研究结果,以了解 48V 轻度混合动力系统在节油方面的实际应用,并提供可靠的证据以用作主动研究的参考。和充电状态。该研究提出其研究结果,以了解 48V 轻度混合动力系统在节油方面的实际应用,并提供可靠的证据以用作主动研究的参考。
