Abstract: A method for controlling a hybrid powertrain system includes employing a system constraints function to identify a feasible solution for an objective variable that satisfies a plurality of independent and dependent constraints for an objective function. The objective variable is associated with a parameter of the hybrid powertrain system. Upon determining that the system constraints function fails to provide a feasible solution for the objective variable that satisfies all of the independent and dependent constraints, a problem recomposition scheme is executed to remove all of the dependent constraints and then reapply and adjust selected ones of the dependent constraints to obtain a feasible solution for the system constraints function that achieves a preferred state for the objective variable.

Abstract: Methods and systems for performing flocking while executing a fleet plan are provided. An example method includes receiving a sequence of coverage requirements for a region and an associated period of time, and determining a respective sequence of intended destinations for each of one or more vehicles of a fleet of vehicles to travel to over the period of time. Additionally, based on a determined sequence of intended destinations for a vehicle of the one or more vehicles and based on a desired spatial relationship between the vehicle and one or more neighboring vehicles for a given time period, a flocking-based direction of travel for the vehicle may be determined for the given time period.

Abstract: In an active suspension system for actively suspending a plant, a fail-safe system controlled by a failure-detector has a selectively-activated damper coupled to the plant. The damper may be a separate element from the actuator. Under normal circumstances, the damper is deactivated and therefore generates no damping force. However, if the failure detector detects an abnormal state in the system, it activates the damper, thereby causing a damping force that resists motion of the plant.

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.

Abstract: A brake valve diagnostic and reporting system for a pneumatic only brake valve on a rail car which includes a brake pipe transducer for measuring brake pipe pressure; and a brake cylinder transducer for measuring brake cylinder pressure. A processor receives measurements from the transducers, compares the measurements against stored brake performance profiles, determines brake status from the comparison and prepares an event report for preselected brake statuses. A wireless transmitter connected to the processor transmits the report. An energy storage device powers the processor and transmitter.

Abstract: A vehicular interface may include an electromechanical interface between a handheld electronic device and subsystems on a vehicular bus or network. In selected embodiments the interface may operate in a “master mode” when a handheld device, such as a tablet computer or smart-phone, is not inserted therein. In this mode the interface may serve as a master controller and accesses and controls various subsystems on a vehicle (such as engine control subsystems, media controllers, navigation systems, sensors and transducers) as a master controller. In one embodiment, when a tablet device is inserted into the interface, the interface may automatically switch to “slave mode” in which it acts as an adapter or interface between the tablet device and the vehicular subsystems. In this mode of operation the user's exclusive interface is through the tablet computer and the tablet computer serves as the master controller for the system.

Abstract: A method is provided for operating a hybrid vehicle equipped with an internal-combustion engine and an electric drive for generating vehicle propulsion. The vehicle selectively is driven in a first operating mode exclusively by the electric drive or in a second operating mode is driven by the internal combustion engine and by the electric drive, or in a third operating mode is driven exclusively by the internal combustion engine. In the first operating mode, the driver predefines a desired driving torque via a selection element. The first operating mode is maintained even if the desired driving torque is greater than a maximal driving torque that can presently be supplied by the electric motor.

Abstract: In normal times, a rotation angle restriction mechanism in a first state restricts a rotation angle of a steering member within a first rotation angular range. In the event of a failure, that is, when there is a malfunction in a steering angle sensor, the rotation angle restriction mechanism is switched into a second state by an electromagnetic clutch, and the rotation angle of the steering member is restricted within a second rotation angular range. A steering direction is detected on the basis of at which one of a pair of terminal ends of the second rotation angular range, the steering member is located. An ECU executes drive control on a steering system actuator on the basis of the detected steering direction.
