The invention relates to the technical field of electric power steering, in particular to a calculation method based on EPS angle following control, which comprises a target angular velocity calculation method and a target torque calculation method.Compared with the prior art, the calculation method solves the problems of too slow response time and response clamping stagnation under the conditions of small angle and small rotating speed; the requirement for the EPS corner following performance in the full vehicle speed section is met, and meanwhile the technical effects that shaking is avoided at the low vehicle speed, timely following is achieved at the high vehicle speed, and shaking on uneven road surfaces is relieved can be achieved. 本发明涉及电动助力转向技术领域，具体地说是一种基于EPS角度跟随控制的计算方法，包括目标角速度计算方法、目标扭矩计算方法，本发明同现有技术相比，解决了小角度、小转速下，响应时间过慢、响应卡滞的问题，实现了全车速段对EPS转角跟随性能要求，同时能够实现低车速不抖动、高车速跟随及时、不平整路面减缓抖动的技术效果。
