Patent number: 8862346Abstract: 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.Type: GrantFiled: March 20, 2012Date of Patent: October 14, 2014Assignee: Eaton CorporationInventors: Benjamin J.

Patent number: 7603219Abstract: 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.Type: GrantFiled: February 22, 2008Date of Patent: October 13, 2009Assignee: Eaton CorporationInventors: Sameer A.
