Abstract: A method, device and terminal apparatus for invoking an automatic driving reference line are provided. The method includes: acquiring lane information of a current lane where a vehicle is located; calculating an automatic driving reference line of the current lane according to the lane information of the current lane; invoking lane information of a switching lane according to a topological relation between the current lane and the switching lane; and calculating an automatic driving reference line of the switching lane according to the automatic driving reference line of the current lane and the lane information of the switching lane.

Abstract: A method and apparatus for planning a travelling path, and a vehicle are provided. The method includes: determining at least one reference curve covering a first length range, and selecting a target reference curve covering the first length range from the at least one reference curve covering the first length range; extracting a curve to be adjusted covering a second length range from the target reference curve covering the first length range; processing the curve to be adjusted based on a safety parameter within the second length range, to obtain an adjusted curve; and determining a travelling path covering the first length range based on the adjusted curve and the target reference curve. The complexity of an actual traffic scene is taken into account, and a travelling path planning is not affected by the accuracy of sampling points.

Abstract: A method and apparatus for processing a driving reference line, and a vehicle are provided. The method comprises: acquiring position information of at least one obstacle in a range covered by an original driving reference line; determining a safety range parameter based on the position information of the at least one obstacle; adjusting a coefficient of a polynomial curve corresponding to the original driving reference line based on the safety range parameter, to obtain an adjusted polynomial curve; and determining an adjusted driving reference line based on the updated polynomial curve. The safety problem of the driving reference line caused by the insufficient obstacle avoidance ability of the driving reference line is solved.
