Abstract: Systems, methods and computer-readable media for path planning for an autonomous vehicle, comprising receiving data defining an upper bound of a spatio-temporal convex corridor and lower bound of the spatio-temporal convex corridor; computing a plurality of control point times within a corridor start time and a corridor end time, the control point times including at least a start control point time, an end control point time and an intermediate control point time between the start control point time and the end control point time; determining, for each of the control point times, respective control point maximum values and control point minimum values; computing, based on the respective control point maximum values and the respective control point minimum values, respective control point values for each of the control point times, the control point values defining a curve segment that is within the upper bound and the lower bound of the spatio-temporal convex corridor.

Abstract: The present application discloses autonomous driving methods and apparatuses that may be applied to an intelligent vehicle and an autonomous driving vehicle. An example method includes: obtaining a motion status of an obstacle; determining a location of a towing point and a speed of the towing point based on the motion status of the obstacle, where both the location of the towing point and the speed of the towing point are continuous functions of the motion status of the obstacle; and obtaining expected acceleration of an ego vehicle based on the location of the towing point and the speed of the towing point.
