摘要：

       为了探究降低某型多用途车(MPV) 综合油耗的技术路线和实现方法，该文建立了一个48 V 混动系统控制模型，设计了启停、快速启动发动机、电机助力和制动能量回收等核心控制策略。在硬件在环（HIL）台架上开展了模型仿真测试，基于提出的控制策略，在实车上完成了策略的验证和优化。结果表明：48 V 混动系统可以实现新欧洲行驶工况（NEDC）综合油耗降低14%，显示出48 V 系统在基本不影响排放的前提下对于降低整车油耗的优势。

Abstract:

A 48 V hybrid system control model which included the core functions such as start-stop, fast engine start, torque assistant and braking energy recovery was built to investigate the technical routine and method of fuel consumption reduction for a multi-purpose vehicle (MPV). The hybrid system control model was test
by hardware-in-the-loop (HIL), and the control strategy and data were validated and optimized at real vehicle. The results show that the 48 V hybrid system control model can decrease the fuel consumption by 14% under the New European Driving Cycle (NEDC) with a slight emission deterioration comparing with conventional configuration vehicles.
