Simulation Verification on State Estimation and Coordinated Control

Abstract

Chapters 3 and 4 discussed the state estimation and coordinated control of distributed electric drive vehicle, so as to provide the state estimation method and coordinated control method for verification, and develop the dynamics simulation platform for the distributed electric drive vehicle. The simulation platform can be used for performing repeated simulation under different working conditions, and comparing and analyzing the state estimation and dynamic control effects of motion states of full vehicle under different adhesion conditions, different motion states and different drivers’ operation conditions, so as to verify the key development technology. The simulation results indicate that the proposed State Estimation system has higher precision and better real-time property and robustness, and the proposed vehicle coordinated control system comprehensively improves the longitudinal and lateral properties of vehicle under the conditions of drive failure, drive trackslip, etc., so as to ensure the safety of vehicle.
