汽车智能化与智能出行

汽车动力系统控制涵盖了从小惯量发动机工作过程高频控制,到大惯量车辆行驶工况的低频控制,涉及油量控制、转矩控制和能量管理三个层面的一系列核心关键问题。本室与骨干企业组成的合作研究团队对此进行了十多年系统研究,构建了以内燃机燃烧过程闭环控制为基础,以热- 机-电协调控制为核心的车用动力系统控制新平台。部分技术成果已开始产业化。

Vehicle powertrain control covers a wide range from high frequency problems such as engine process control, to low frequency problems which as vehicle management. It contains three key issues: combustion control, torque control and energy management. Cooperating with industrial partners, the state key lab has been working on this topic for over 10 years, and has built up a new control platform based on close-loop combustion control for IC engines and coordination control of thermodynamics, mechanics and electric systems. A part of the achievements start to be commercialized.
