Autonomous Vehicle Having Multiple Compute Lane Motion Control

An autonomous vehicle includes a first compute lane, the first compute lane including a first motion planner configured to output a first motion trajectory at a first planning cycle; a second compute lane, the second compute lane including a second motion planner configured to output a second motion trajectory; and one or more processors configured to: obtain data describing the first motion trajectory from the first motion planner; provide the data describing the first motion trajectory to the second motion planner; generate the second motion trajectory by the second motion planner at a second planning cycle based on the data describing the first motion trajectory from the first motion planner; and control an autonomous vehicle in accordance with the first motion trajectory.
