System and method for the quantification of the steering feel of the viscous damping in the case of a vehicle; the is equipped with an electric power assisted steering system

摘要

A method for quantifying a viscous damping of steering feel properties of the shaft for a vehicle with an electric power steering system, the connection of the electric power assisted steering system (eps) with a rotary actuator and the axle leg bolt adjusting drives of a simulator system, which is a triangle shafts expensive control input of a simulator to the rotary drive, and receive outputs from sensors in the simulator system of the simulator control in response to the triangle shafts expensive input. The simulator control is programmed logic, which is a method with the use of the triangle is expensive input shafts, which by means of the rotary drive is provided and deconvolution for the removal of the phase delay between the input - and output signals for generating a volume of decontamination that hysteresis loop for each of a plurality of a steering column cycles is carried out, during a vehicle simulation event, and a viscous damping steering feel properties of the shaft of the eps - system to characterize.
