The assist characteristic of variable assist steering system is studied by means of theoretical anal-ysis, numerical simulation and experience statistics. A design method of variable assist steering characteristic aiming at road feel of driver is put forward, and a vehicle simulation test on the characteristic is conducted. The results show that the variable assist characteristic obtained can not only meet the requirements of steering handiness at low speed driving but also assure proper road feel and essential feel of stability at high-speed operation.
