  • Patent number: 10464547
    Abstract: A vehicle includes drive wheels, an energy source having an available energy, a torque-generating device powered by the energy source to provide an input torque, a transmission configured to receive the input torque and deliver an output torque to the set of drive wheels, and a controller. The controller, as part of a programmed method, predicts consumption of the available energy along a predetermined travel route using onboard data, offboard data, and a first logic block, and also corrects the predicted energy consumption using the onboard data, offboard data, and an error correction loop between a second logic block and the first logic block. The controller also executes a control action with respect to the vehicle using the corrected energy consumption, including changing a logic state of the vehicle.

  • Patent number: 8871339
    Abstract: A modified clay is provided, which includes a layered clay material intercalated with a modifier having a conjugated double bond and capable of producing free radicals when heated. A clay-polymer composite is also provided, which includes a polymer material and the modified clay, wherein the modified clay is dispersed in the polymer material and at least partially exfoliated. The modifier is capable of producing free radicals when heated to scavenge free radicals generated from thermal cracking or burning of the polymer material to prevent further thermal cracking of the polymer material.

  • Patent number: 8862346
    Abstract: A mobile computing apparatus simulates the performance of a virtual vehicle using the route, driving behavior and loading experience of a baseline vehicle. The baseline vehicle is instrumented and operational data is collected, forming a data set. The apparatus includes simulator logic configured to construct a duty cycle from the data set representative of the operation of the baseline vehicle during travel along the route (e.g., a loading duty cycle). The data set includes route data with distance and vehicle speed information, engine data associated with the engine, and operational element data. The logic defines a virtual vehicle that is the same as the baseline vehicle but that includes a virtual operational element, such as a transmission, that is different than that in the baseline vehicle. The logic determines a performance characteristic, such as fuel economy, of the virtual vehicle using the constructed duty cycle.

  • Patent number: 7603219
    Abstract: A method is disclosed for computing clutch engagement characteristics of a friction clutch system in a vehicle powertrain. A dynamic model of the system is used under conditions that cause clutch slipping. Algebraic equations defining a functional relationship between clutch torque and an engagement angle have characteristic parameters that are estimated using a non-linear least squares technique. The non-linear least squares technique repetitively minimizes the difference between a measured clutch output speed and a clutch output speed from the system dynamic model for the same inputs until a small insignificant error is reached. Parameter estimates are used to update each engagement characteristic.

A dynamic model of the system is used under conditions that cause clutch slipping. Algebraic equations defining a functional relationship between clutch torque and an engagement angle have characteristic parameters that are estimated using a non-linear least squares technique. A non-linear least squares technique iteratively minimizes the difference between a measured output clutch disk speed and an output clutch disk speed from the system dynamic model for the same inputs until a small insignificant error is reached.
