Study on the Control Strategy of Slope Starting for Pure Electric Vehicle

摘要

In order to ensure that pure electric vehicle can accurately identify the road grade, and has a high safety and good feeling, this article proposes a control strategy for slope starting of pure electric vehicle. Slope prediction module can accurately calculate and predict the road grade based on motor speed and vehicle-related parameters. Slope starting strategy allows the vehicle to stop on a small slope, and keep a low speed on a large slope, and can make the feeling of slope starting consistent with the common road. This article completed the offline simulation under MATLAB/Simulink, and simulation results showed that the control strategy not only can accurately identify the road grade, but also has a high safety and good feeling.
