摘要
在现有电动轮汽车的基础上,提出了一种实现主动转向和助力转向功能的方案。介绍了新型电动轮转向系统的结构和基本工作原理,并建立了新型电动轮转向系统与整车机电耦合的动力学模型。提出了主动转向与助力转向的控制策略,并进行了不同车速工况下新型电动轮转向系统的性能分析。仿真结果表明,所提出的实现主动转向和助力转向功能的系统结构方案是可行的,所设计的主动转向与助力转向的控制策略是有效的。
On the base of exiting electric vehicle,a scheme for realization of active steering function and power steering function was proposed.System structure and basic operation principle of the novel differential steering system with in-wheel motor were described in detail,and dynamic models of electro-mechanical coupling for the novel steering system and vehicle were built.Then,control strategies of active steering and power steering were put forward,and performance analysis of the novel differential steering system with in-wheel motor was carried out in different vehicle speed conditions.Simulation results indicate that the system scheme for realization of active steering function and power steering function is feasible,and the control strategies of active steering and power steering are effective.
