Navigation method and system and intelligent driving equipment

The invention discloses a navigation method and device and intelligent driving equipment, and the method comprises the steps: determining the lane-level topology of a road between a current position and a target position according to the road-level topology of the road between the current position and the target position of the intelligent driving equipment and the number of lanes; determining the feasible degree of each lane-level path in at least two lane-level paths from the current position to the target position according to the lane-level topology; according to the current lane of the intelligent driving equipment and the feasible degree of each lane-level path, first navigation information is generated, and the first navigation information indicates a first lane-level path from the current position to the target position. The method can be applied to intelligent driving equipment such as a new energy automobile and an electric automobile, lane-level navigation can be realized in the absence of a high-precision map, the navigation precision can be improved, and automatic driving can be popularized and used nationwide or globally.
