Abstract
A method and device for amending a reference path associated with a vehicle are disclosed. The method includes: (i) acquiring road segment data and reference path data, the reference path data having a plurality of anchor points defining the reference path along the road segment, (ii) using the road segment data and the reference path data to determine a safe deviation interval for each one of the plurality of anchor points, a given safe deviation interval for a given anchor point being indicative of an acceptable deviation of the vehicle from the reference path; and (iii) using the safe deviation intervals to determine an amended path for the vehicle instead of the reference path, such that by following the amended path the vehicle falls within the constraints of the road segment.
