Parallel and failover autonomy systems

An autonomous vehicle is operated using a main autonomy system that analyzes data collected by a sensor system of the autonomous vehicle to determine a trajectory of travel of the autonomous vehicle, and wherein the main autonomy system provides instructions to a propulsion system of the autonomous vehicle to cause the propulsion system to navigate the autonomous vehicle according to the trajectory. In response to determining that navigating the autonomous vehicle according to the trajectory is likely to result in collision, instructions are provided from a parallel autonomy system to the propulsion system to cause the autonomous vehicle to avoid collision. In response to detecting a fault in the main autonomy system, control of the propulsion system is provided from the main autonomy system to a failover autonomy system, wherein the failover autonomy system is configured to override the propulsion system.

Aspects of the disclosure relate to controlling a vehicle in an autonomous driving mode using trajectories. For instance, a trajectory may be received by one or more first computing devices from one or more second computing devices. While the first computing devices are controlling the vehicle in the autonomous driving mode based on the trajectory, an error may be generated by second computing devices. Whether the error is a recoverable error may be determined, and if so, the second computing devices attempt to generate a new trajectory. When the second computing devices generate the new trajectory, the vehicle may be controlled by the first computing devices according to the new trajectory.
