Abstract:

A method of segmeted parabola-type assistance characteristic was brought out to realize the curve-type assistance characteristics of the electric power steering system,and a single chip-microcomputer-based controller was designed to carry out the task.The mathematical model of single chip microcomputer control system was constructed,and Z transform was used to analyse the stability of the system.The test result shows that single chip microcomputer control system can realize the curve-type assistance characteristics.

Key words: electric power steering system;control system, curve-type;assistance characteristic
