摘要
针对某带APU的增程式城市电动客车的整车协调控制问题设计了整车控制器,研究了整车控制器的硬件、软件设计,多能源管理和能量优化控制策略。通过动力电池组荷电状态SOC逻辑门限控制策略,当动力电池组SOC低于门限值后,APU开启,起到增程器的作用。整车控制器以瑞萨科技的32位微控制器uPD70F3380为核心,实现数字I/O、模拟量的采集以及CAN总线通信、多能源管理和能量优化控制等功能。经过实车实验,该整车控制器实现了电动客车的APU驱动、混合驱动、纯电驱动等多种工作模式,并有效地提高了能量的利用率,证明了该整车控制器的可行性和控制策略的有效性。
A new vehicle control unit was designed for coordinating control problem for an extended range electric bus using APU;This paper mainly studies on hardware and software design, muhienergy management and energy optimization control strategy. Using SOC, logic gate limit control strategy of the state of charge of the battery pack, when battery SOC is lower than the threshold, APU open, playing the role of extended range. The uPD70F3380 32bit MCU made by Renesas Electronics company is used as core controller in the system, achieving Digital I/O, analog acquisition and CAN bus communication, multi-energy management and energy optimization control strategy and so on. Several working modes such as APU drive, hybrid drive, pure electric drive were tested, and vehicle control unit effectively improves the utilization of energy, proving the feasibility of the vehicle controller and the effectiveness of the control strategy.
