汽车电动助力转向系统硬件在环仿真及实车验证

The auto EPS hardware in the loop simulation and real vehicle test

一款汽车的电动助力转向系统开发成功与否控制策略的设计是关键,因其影响整车的操纵稳定性,安全舒适性等人们关注的性能,如果能够实现在开发初期对设计的控制策略进行硬件在环测试然后根据仿真的结果进行调整控制策略,样件制作后再进行实车验证,可以避免设计弯路从而缩短开发周期和成本,这是进行电动助力转向产品开发的新思路,对促进国内电动助力转向行业的发展和提高我国汽车行业竞争力都具有重要的意义。

a car of electric power steering system development the design of the control strategy is the key to success,because of the impact of vehicle handling stability,safety comfort people focus on performance,if can achieve at the beginning of the development to design the control strategy of hardware in loop test and adjust according to the result of the simulation control strategy of the reentry after samples are making real vehicle test and verify,can avoid detours and shorten the development cycle and cost,this is for electric power steering product development of new ideas,to promote the development of domestic electric power steering industry and enhance the competitiveness of China's automobile industry has important significance.
