Research on Failure Mechanism for Distributed Drive Vehicle Based on Co-simulation of Carsim and Matlab

Abstract

Distributed drive vehicles adopt multi-motor distributed drive, which makes it show advantages that traditional vehicles do not have, at the same time, it results in new problems to the reliability of the system. This paper takes four-wheel independent driven vehicle as the research object. Aiming at the failure of the in-wheel motors of distributed drive vehicles,a distributed motor drive vehicle model is built based on Carsim and Simulink. Based on the simulation verification of the established model, the simulation experiments for failure conditions are designed, and the results are analyzed. The results show that the established model basically satisfies the experimental requirements, and the failure analysis can provide a basis for subsequent fault-tolerant controller design.
