Abstract: A limiting system for constraining a commanded steering angle for a vehicle including an electric power steering (EPS) system includes a controller in electronic communication with at least one other system of the vehicle. The controller executes instructions to receive a plurality of trajectory planning inputs that are each expressed as an array including a plurality of values, where the plurality of trajectory planning inputs includes a trajectory velocity array, a trajectory acceleration array, and a trajectory curvature array. The controller also executes instructions to determine a maximum rate of steering angle change based on the corresponding ideal rate of change of the commanded steering angle and the maximum rate change allowed by the EPS system.

Abstract: A vehicle control system for automated driver-assistance includes a model-based controller that generates a first control signal to alter an operation of a plurality of actuators of a vehicle based on a reference trajectory for the vehicle, and a present state of the vehicle and actuators. The vehicle control system further includes a neural network controller that generates a second control signal to alter the operation of the actuators of the vehicle based on a reference trajectory for the vehicle, and the present state of the vehicle and actuators. The vehicle control system further includes a combination module that combines the first control signal and the second control signal to operate the actuators based on a combined signal.

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 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 system, for use in protecting an active-material actuator from overheating without using a temperature 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 being 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 operations comprising obtaining a value for electrical resistance of the pre-tensioned active material, estimating, based on the electrical resistance obtained, an strain value for the active material, yielding an estimated strain value, and obtaining an actual strain value for the active material. The operations also include determining a difference between the estimated strain value estimated and the actual strain value and determining, based on the difference determined, whether an overheating condition exists for the active material.

Abstract: A linear motion device includes a rod extending along a longitudinal axis, and a plurality of actuator units. Each of the plurality of actuator units includes at least one Shape Memory Alloy (SMA) element that is attached to a coupling mechanism. The at least one SMA element of each if the plurality of actuator units moves the coupling mechanism along the longitudinal axis, and into grasping engagement with the rod. Each actuator unit moves the rod a unit movement distance along the longitudinal axis in response to a control signal. The plurality of actuator units are actuated repeatedly in a cyclic order to move the rod in a continuous linear motion a distance greater than the unit movement distance of each of the plurality of actuator units.
