Abstract
Changes in the controlling of an autonomous vehicle are caused based on an operational risk determined for the autonomous vehicle. An operational risk monitor module of the autonomous vehicle uses information about objects detected within an environment in which the autonomous vehicle is located and predicted behaviors of those objects to assess the operational risk of the autonomous vehicle along a planned path. The operational risk is used to determine whether to cause a change in the controlling of the autonomous vehicle, for example, based on a comparison between the operational risk and a previously estimated operational risk or based on a determination that the operational risk exceeds a threshold. The operational risk monitor module transmits a signal to one or more control system modules of the autonomous vehicle to indicate to change the controlling of the autonomous vehicle based on the operational risk.
