Abstract: A lifting mechanism includes a load bearing structure, and a carrier. The carrier is configured for supporting a load. The carrier is moveable relative to the load bearing structure in a substantially vertical direction relative to a ground surface, along a vertical axis. A load carrying spring applies a spring force that biases the carrier relative to the load bearing structure in a direction along the vertical axis. A negative stiffness device interconnects the carrier and the load bearing structure. The negative stiffness device applies a device force that biases the carrier relative to the load bearing structure in a direction along the vertical axis. The device force opposes the spring force. The device force includes a magnitude that is substantially equal to the spring force in any of a plurality of different positions of the carrier relative to the load bearing structure along the vertical axis.

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.

Abstract: A non-linear stiffness actuator for a suspension corner employed in a vehicle includes an actuator housing and an actuator shaft configured to transmit an actuator force to the road wheel. The actuator also includes a primary elastic member assembly arranged between the actuator housing and the actuator shaft and configured to exert a primary elastic member force along the actuator shaft. The actuator additionally includes a secondary elastic member assembly configured to exert a variable secondary elastic member force acting between the actuator housing and the actuator shaft. The variable secondary elastic member force is configured to selectively contribute to and subtract from the primary elastic member force to thereby facilitate the non-linear stiffness of the actuator. A vehicle having such a non-linear stiffness actuator is also provided.

Abstract: A system for estimating a position associated with a pre-tensioned active material without using a position sensor. The system includes an active material being transformable between a first state and a second state in response to a pre-determined stimulus and pre-tensioned to at least a pre-determined threshold, yielding the pre-tensioned active material. The system also includes a processing unit configured to perform various operations. The operations include obtaining a value for electrical resistance of the pre-tensioned active material. The operations also include estimating, using the electrical resistance determined, the position associated with the pre-tensioned active material.

Abstract: A suspension assembly between a sprung element and an unsprung element includes a load-carrying spring and a negative stiffness element between the sprung element and the unsprung element. The load-carrying spring element is configured with a positive spring rate to support a static load of the sprung element. The negative stiffness element is configured with a negative spring rate and is configured to exert a force opposing the spring rate of the spring, the negative spring rate has a magnitude that cancels the positive spring rate at a zero deflection point of the suspension assembly. The suspension assembly also includes an active trimming mechanism which is configured to move a plurality of pivot points of the negative stiffness element to achieve a trimmed position of the negative stiffness element.
