METHOD AND SYSTEM FOR STITCHING PLANNING TRAJECTORIES FROM CONSECUTIVE PLANNING CYCLES FOR SMOOTH CONTROL EXECUTION OF AUTONOMOUS DRIVING VEHICLES
METHOD AND SYSTEM FOR STITCHING PLANNING TRAJECTORIES FROM CONSECUTIVE PLANNING CYCLES FOR SMOOTH CONTROL EXECUTION OF AUTONOMOUS DRIVING VEHICLES
According to one embodiment, an ADV is controlled according to a first trajectory planned during a first planning cycle. A control error is determined which represents a drifting error at a first location of the ADV at a first point in time at the end of the first planning cycle. A second point in time is selected on the first trajectory. A second trajectory is generated from a second location on the first trajectory corresponding o the second point in time as a starting location of the second trajectory for a second planning cycle as a next planning cycle. A segment of the first trajectory between the first point in time and the second point in time is combined with the second trajectory to generate a third trajectory for the second planning cycle. The ADV is driven and controlled according to the third trajectory corresponding to the second planning cycle.
