Abstract
An autonomous vehicle configured for active sensing may also be configured to weigh expected information gains from active-sensing actions against risk costs associated with the active-sensing actions. An example method involves: (a) receiving information from one or more sensors of an autonomous vehicle, wherein one or more control processes for an autonomous vehicle are based upon the information, (b) determining an information-improvement expectation that corresponds to an active-sensing action, (c) determining a risk-cost that corresponds to the active-sensing action; and (d) based on both (i) the information-improvement expectation for the active-sensing action and (ii) the risk-cost for the active-sensing action, determining whether the active-sensing action is advisable.
