| Zusammenfassung: | The invention provides a path planning method and system. The method comprises the following steps: firstly, determining n typical road sections; then letting h = 1; calculating the similarity between the h-th unsampled road section and each typical road section based on a fuzzy reasoning method; calculating a speed weight corresponding to the h-th unsampled road section according to the similarity between the h-th unsampled road section and each typical road section; calculating road impedance corresponding to the h-th unsampled road section according to the speed weight corresponding to the h-th unsampled road section until h =k, wherein k is the total number of the unsampled road sections; and finally, planning a driving path according to the road impedance corresponding to each unsampled road section. On the basis of the principle that the larger the road impedance is, the lower the safety is, the road sections with steep slopes and narrow view fields are effectively avoided, the chances that the roads wi |
