Abstract: In a recovery control method for a secondary battery that includes a positive electrode containing a positive electrode active material, a solid electrolyte, and a negative electrode containing a negative electrode active material containing at least a lithium metal or a lithium alloy, and is fastened from an outside, the recovery control method includes: measuring cell resistance of the secondary battery; calculating a recovery limit resistance value indicating an upper limit value of resistance that ensures recovering the secondary battery from a depth of charge/discharge of the secondary battery, a cell temperature of the secondary battery, and a pressure applied to the secondary battery; and inhibiting charging/discharging the secondary battery and executing recovery control that recovers the secondary battery when a resistance value of the cell resistance is equal to or less than the recovery limit resistance value.

Abstract: An occlusion is identified in a vehicle transportation network. A visibility grid is identified on a second side of the occlusion for a vehicle that is on a first side of the occlusion. The visibility grid is identified with respect to a region of interest that is at least a predefined distance above ground. The visibility grid is used to identify first portions of roads sensed by a sensor positioned on the vehicle and second portions of the roads that are not sensed by the sensor. A driving behavior of the vehicle is altered based on the visibility grid.

Abstract: A method identifies a particular speaker from among a set of speakers via a computer that includes a computer memory in which voice signatures, each associated with one of the speakers in the set, are stored. The method includes acquiring a voice signal produced by the particular speaker, constructing a new voice signature in accordance with the voice signal, comparing the new voice signature with at least one of the voice signatures stored in the computer memory, and identifying the particular speaker in accordance with the result of the comparison. The method also includes, before the constructing, generating a complete signal that includes the voice signal and at least one predetermined extension signal. Accordingly, the constructing also includes, constructing the new voice signature in accordance also with each extension signal.

Abstract: A controller includes an extraction unit, an arrival time calculation unit, a departure time calculation unit, a stop location calculation unit and a transmission unit. The extraction unit extracts stop-scheduled vehicles, which are scheduled to stop in a stopping area. The arrival time calculation unit calculates arrival times when the stop-scheduled vehicles will arrive at the stopping area based at least on user-side information of users who use the stop-scheduled vehicles, or on position information of the stop-scheduled vehicles. The departure time calculation unit calculates a scheduled departure order indicating an order in which the stop-scheduled vehicles will depart the stopping area. The stop location calculation unit calculates stop locations of the stop-scheduled vehicles based on the scheduled departure order. The transmission unit transmits information indicating the stop locations to the stop-scheduled vehicles.

Abstract: A method for use in traversing a vehicle transportation network by an autonomous vehicle (AV) includes traversing, by the AV, the vehicle transportation network. Traversing the vehicle transportation network includes identifying a distinct vehicle operational scenario; instantiating a first decision component instance; receiving a first set of candidate vehicle control actions from the first decision component instance; selecting an action; and controlling the AV to traverse a portion of the vehicle transportation network based on the action. The first decision component instance is an instance of a first decision component modeling the distinct vehicle operational scenario.

Abstract: Traversing a vehicle transportation network includes operating a scenario-specific operational control evaluation module instance. The scenario-specific operational control evaluation module instance includes an instance of a scenario-specific operational control evaluation model of a distinct vehicle operational scenario. Operating the scenario-specific operational control evaluation module instance includes identifying a multi-objective policy for the scenario-specific operational control evaluation model. The multi-objective policy may include a relationship between at least two objectives. Traversing the vehicle transportation network includes receiving a candidate vehicle control action associated with each of the at least two objectives. Traversing the vehicle transportation network includes selecting a vehicle control action based on a buffer value. Traversing the vehicle transportation network includes performing the selected vehicle control action, determining a preference indicator for each objective, and updating the multi-objective policy.
