摘要

本研究提出了一种基于非线性模型预测控制(NMPC)的驾驶控制器设计方法,适用于配备无级变速器(CVT)的内燃机(ICE)汽车。考虑了离合器接合和分离模式、发动机开启和关闭模式以及发动机制动效应。车辆系统动力学的切换特性被放宽为连续转换。这样就可以使用标准的 NMPC 软件包来解决 NMPC 问题。数值示例表明,所设计的控制器能够实现基于 NMPC 的实时驾驶控制。

Nonlinear model-predictive driving control of ICE vehicles equipped with CVTs via relaxation of switching behaviours
In this study, a design method of driving controller based on nonlinear model predictive control (NMPC) is presented for internal-combustion-engine (ICE) vehicles equipped with continuously variable transmissions (CVTs). The clutch-engaged and -released modes and engine-on and -off modes are considered, along with the engine-braking effect. The switching characteristics of the vehicle system dynamics are relaxed into continuous transitions. This allows for the use of standard NMPC software packages to solve the NMPC problem. Numerical examples indicate that the designed controller is capable of achieving real-time driving control based on NMPC.
