| Abstract: | A system model of EPS is established for the steering feel of EPS,and the current dominance part is regarded as a black-box.Firstly steering feel function is put forward and on the basis of the function the characters of the system is analyzed.The function expression of the black-box is sought in reverse aiming at system characters and frequency domain and the time domain are also analyzed.The analysis shows that the transferring function of the steering feel of EPS is bi-rank function.The black box can be ... |
