Abstract: A spring-damper assembly for a suspension corner employed in a vehicle having a vehicle body and a road wheel includes a fluid spring configured to suspend the vehicle body relative to the road wheel. The spring-damper assembly also includes a damper configured to attenuate compression and rebound oscillations of the fluid spring. The spring-damper assembly additionally includes a spring-seat housing configured to retain the fluid spring and establish a position of the fluid spring relative to the damper. The spring-seat housing includes an inner surface defining a contour configured to guide the fluid spring upon compression thereof around the damper and define a non-linear stiffness of the fluid spring.

Abstract: A system for adaptive in-drive updating, for a vehicle travelling on a route, includes a controller adapted to obtain a pre-drive energy consumption prediction for the route, via an energy consumption predictor. An in-drive updating module is selectively executable by the controller at a timepoint during the route at which a completed portion of the route has been traversed and a remaining portion remains untraversed. The controller is adapted to obtain an actual energy consumption for segments in the completed portion of the route. The controller is adapted to obtain at least one modification factor based on a comparison of the actual energy consumption and the pre-drive energy consumption prediction for the segments in the completed portion of the route. The pre-drive energy consumption prediction for the remaining portion of the route is adjusted based on the modification factor.

Abstract: A strut assembly for a suspension corner employed in a vehicle having a vehicle body and a road wheel includes a damper. The strut assembly also includes an elastic unit having at least one spring module acting in concert with the damper to suspend the vehicle body relative to the road wheel. Each spring module has a positive stiffness spring arranged in parallel with a negative stiffness spring. A vehicle that has a suspension corner employing the elastic unit and is configured to maintain contact between the road wheel and the road surface and provide isolation of vibration between the road wheel and the vehicle body is also contemplated.

Abstract: A system and method for wirelessly controlling a shape memory alloy (SMA) actuator using magnetic resonant coupling (MRC). The SMA actuator is part of a receiver circuit including an actuator coil, where the SMA actuator is configured into a certain shape. The system includes a transmitter circuit having a transmitter coil and a controller, where the transmitter coil receives an AC current that causes the transmitter coil to generate an oscillating magnetic field in resonance with the actuator coil in the receiver circuit and be magnetically coupled thereto. The current induced in the actuator coil creates heat that reconfigures the SMA actuator to provide the actuation.

Abstract: A method that includes obtaining demand data, consumer data, and historical demand data, the demand data represents a demand of consumers for a supply over a past time period in a geographic zone. The demand data includes a recent time segment having unreliable demand information. The consumer data. The method further includes, based on the demand data, estimating a scalar of the demand, and, based on the historical demand data, modeling a standardized model demand profile of mean demand over multiple past time periods. Further, the method includes producing a short-term demand prediction of the consumers of the supply over a portion of a forthcoming time period. The short-term demand prediction is based, at least in part, on the standardized model demand profile, the demand data, and the consumer data.

Abstract: A system for tuning a trajectory tracking controller for a vehicle includes a trajectory planner configured to generate the planned trajectory and to output one or more planned trajectory components representative of the planned trajectory, a model predictive controller including an internal model and an optimizer, and a tuning neural network configured to receive the one or more planned trajectory components and one or more measured trajectory components and to produce weights for a cost function. The internal model is configured to receive a predicted control input from the optimizer and the one or more measured trajectory components and to produce a predicted output. The optimizer utilizes a cost function and is configured to receive the weights for the cost function and a predicted error and to produce the predicted control input, wherein the predicted error is a selected one of the planned trajectory components minus the predicted output.
