Abstract: An intelligent driving method causes a vehicle to perform roaming based on a high-definition map, where the roaming can include lane switching, driving direction changing, or partial navigation strategy changing. The vehicle may perform the lane switching, the driving direction changing, or the partial navigation strategy changing based on an operation of a driver.

Abstract: A method for guiding driving of a vehicle includes generating M lane topology curves based on an obstacle and lane lines at an intersection, an obstacle and lane lines on a driving-in road at the intersection, and an obstacle and lane lines on a driving-out road at the intersection. The lane topology curve uses as endpoint an end of a driving-in lane of the driving-in road, and a start point of a driving-out lane of the driving-out road. Reasonableness detection is performed on the M lane topology curves to obtain K′ lane topology curves, where K′ is not greater than M. A target path using the K′ lane topology curves may be used to guide the vehicle when the vehicle is located on the driving-in road.
