In order to enhance the estimation accuracy of vehicle sideslip angle, a comprehensive Strong Tracking Unscented Kalman Filter (STUKF) algorithm is herein proposed to estimate the sideslip angle by adding strong tracking theory (STT) into Unscented Kalman Filter (UKF) algorithm in this paper. Firstly, a seven degree-of-freedoms (DOFs) vehicle dynamics model is established. Then based on this established model, the estimators of tire-road friction coefficient and sideslip angle are built up based on STUKF algorithm. Finally, comparative simulations are carried out by utilizing CarSim-MATLAB/Simulink platform to verify the effectiveness of the proposed estimation approach. The simulation results show that, compared with the traditional UKF, the STUKF algorithm can better enhance the estimation accuracy of sideslip angle.

A Simplified Analysis to Predict the Fire Hazard of Primary Lithium Battery

Applied Sciences (2018)

Mingyi Chen Jiahao Liu Dongxu Ouyang Shuchao Cao Zhi Wang

To better understand the fire risk of primary lithium batteries, the combustion properties of different numbers of primary lithium batteries were investigated experimentally in this work. Based on the t2 fire principle and total heat release results from the experiments, a simplified analysis was developed to predict the fire hazard, and especially the heat release rate, of primary lithium batteries. By comparing the experiment and simulation results, the simulation line agrees well with the heat release rate curve based on the oxygen consumption measurements of a single primary lithium battery. When multiple batteries are burned, each battery ignites at different times throughout the process. The ignition time difference parameter is introduced into the simulation to achieve similar results as during multiple batteries combustion. These simulation curves conform well to the experimental curves, demonstrating that this heat release rate simulation analysis is suitable for application in batteries fires.
