本资源是一份关于Toyota Hybrid EV(普锐斯)技术分析报告,由泛亚汽车技术中心有限公司动力总成部于2003年12月发布。报告深入探讨了丰田普锐斯的动力系统、效率、电池技术以及控制系统策略,具有很高的专业价值。 1. **60km/h巡航性能**: 在60km/h的巡航模式下,普锐斯采用混合动力系统运作。MG2作为发电机,将部分发动机功率转化为电能供给电池充电,同时MG1作为电动机驱动车辆。空调开启时,发动机输出功率在4.8kW到5.7kW之间波动,以满足空调压缩机的需求。这一过程有助于提高能量利用效率,并保持电池SOC(荷电状态)在55.5%至59%之间。 2. **动力系统与组件**: 报告详细分析了普锐斯的发动机,包括其规格(如转速和电流数据)、与传统汽油机的比较、结构特点和效率。报告还介绍了Power Split Device(动力分配装置),用于在电动机和发动机之间灵活切换动力。NiMH高压电池系统是关键,包括电池概述、MAIN RELAY SYSTEM(主继电器系统)以及电池管理和DC/DC转换器。 3. **控制系统策略**: 动力总成控制系统与策略是报告的核心部分。它涉及ECU(电子控制单元)的作用、位置及其与其他控制器的接口。报告讨论了发动机在不同工况下的最优运行控制,如启动怠速、全加速、滑行后的再加速以及REG(再生制动)过程。此外,还包括电机控制策略,确保电池SOC平衡以及电池的充放电策略。 4. **工况模式描述**: 普锐斯的工况被分为多个阶段,如起动、起步、加速和不同的行驶模式。报告详细解释了在这些情况下,如何通过智能控制实现高效能和低排放。 这份报告对于理解丰田普锐斯的混合动力技术以及在实际驾驶情境中的工作原理具有很高的参考价值,对汽车行业特别是电动汽车技术发展有深入研究的读者来说是一份宝贵的资料。
