Abstract

Due to the special structure characteristics, the switching process control from pure electrical driving mode to compound driving mode of the single-shaft parallel hybrid powertrain has caught broa...

Highlights

  • Energy crisis and environmental pollution bring new challenges for traditional automotive industry

  • Hybrid electric vehicle (HEV) always has two or more power sources, and different combination of the power sources can form a variety of driving modes

  • An efficient torque coordination control algorithm is very important to improve the performance of HEV power system.[1]

Summary

Introduction

Energy crisis and environmental pollution bring new challenges for traditional automotive industry. The control target requires that both sides of the clutch can track the output signal of the reference model rapidly, so that the rotational speed of the clutch driving side can match the rotational speed of the clutch driven side In this way, the clutch sliding friction loss is reduced to minimize the longitudinal impact of the vehicle during mode switching process. Smaller than a certain threshold, the clutch gets into a Detailed steps include establishing the discrete linear sliding stage, which is recognized as the specific model of the clutch-oriented HEV in the mode switching process, calculating the system states and outputs in the prediction horizon, setting and solving the optimization targets, and applying the results to the controlled object.
