| Popis: | In order to study the electric power steering system (EPS) which is suitable for the steering characteristics of commercial vehicles, the effect of weight on steering performance is analyzed, and a dual-motor full-weight EPS system is proposed. Firstly, the full-weight assist characteristics are studied, and two current distribution schemes and corresponding fault-tolerant control strategies are proposed according to the structural characteristics of dual-motor EPS system. By comparing with the traditional single-weight EPS system, it is proved that the full-weight EPS system improves the control stability and makes the driver get a better road feeling. Through the double line change test and step test, the effectiveness of the two current distribution schemes are verified, and it has better fault-tolerance performance. By comparison, the fault-tolerance performance of scheme two is better than that of scheme one. |
