Aspects of the disclosure provide a method of managing maneuvering of an autonomous vehicle in certain situations. For instance, a state of the autonomous vehicle may be identified, for example by one or more processors of a planning system of a vehicle, a state of the autonomous vehicle. Based on the state of the autonomous vehicle, the one or more processors of the forward planning system may determine whether the autonomous vehicle has become stuck. Based on the determination that the autonomous vehicle has become stuck, engaging a maneuver planning system having one or more processors capable of generating trajectories that allow the autonomous vehicle to maneuver in reverse may be engaged. After engaging the maneuver planning system, a new trajectory for the autonomous vehicle to follow may be generated. The autonomous vehicle may be controlled according to the new trajectory.

Managing maneuvers for autonomous vehicles in certain situations

Aspects of the technology relate to exception handling for a vehicle. For instance, a current trajectory for the vehicle and sensor data corresponding to one or more objects may be received. Based on the received sensor data, projected trajectories of the one or more objects may be determined. Potential collisions with the one or more objects may be determined based on the projected trajectories and the current trajectory. One of the potential collisions that is earliest in time may be identified. Based on the one of the potential collisions, a safety-time-horizon (STH) may be identified. When a runtime exception occurs, before performing a precautionary maneuver to avoid a collision, waiting no longer than the STH for the runtime exception to resolve.
