20160040732 | SYSTEM AND METHOD FOR THE UPDATE OF FILL PARAMETERS IN WET CLUTCHES THROUGH CROSS LEARNING - A system and method for updating a set of filling parameters for a wet clutch system is provided. The clutch comprises a piston, a proportional valve, a controller, and a sensor. The method comprises the steps of providing the wet clutch system, providing the set of filling parameters, actuating the wet clutch system based on at least one of the set of filling parameters, sensing a response of the wet clutch system during actuation of the wet clutch system, comparing an observed filling parameter to at least one of the set of filling parameters, calculating a fill error between the observed filling parameter and the at least one of the set of filling parameters, and adjusting a plurality of the set of filling parameters based on the fill error. | 02-11-2016 |
20150354685 | HYDROSTATIC AND DIRECT DRIVE TRANSMISSION - A hydrostatic driveline has a power source, a transmission portion, a hydrostatic pump, a hydrostatic motor, a transfer case, a first axle assembly, an inter-axle drive shaft, and a second axle assembly. The transmission portion is drivingly engaged with the power source. The hydrostatic pump is in driving engagement with the transmission portion. The hydrostatic motor is in fluid communication with the hydrostatic pump. The transfer case is in driving engagement with the hydrostatic motor. The inter-axle drive shaft is in driving engagement with the transfer case and the transmission portion. The transmission portion, the hydrostatic pump, the hydrostatic motor, the transfer case, and the inter-axle shaft form a first power path for the hydrostatic driveline and the transmission portion and the inter-axle shaft form a second power path for the hydrostatic driveline. | 12-10-2015 |
20150143332 | FUNCTIONAL ARCHITECTURE PATTERN FOR SAFETY APPLICATIONS - A process for decomposing safety software involves the steps of providing a first software module associated with a first logical unit, providing a second software module associated with a second logical unit, instructing the first software module to implement a first safety goal based on a quality management level, and instructing the second software module to implement a second safety goal based on a safety integrity level, where the second software module uses at least one input and at least one output of the second logical unit to determine if the second safety goal is satisfied. Consequently, the second software module uses a result of the first software module to determine if the first safety goal has been completed, and the second software module uses at least one algorithm to verify an operational status of the first logical unit. | 05-21-2015 |
20150075146 | METHOD FOR OPERATING A VEHICLE DRIVELINE - A method of operating a driveline including a powersplit transmission is provided. The driveline may be operated in a hydrostatic power transmission mode and a blended hydrostatic/mechanical power transmission mode. The method comprises the steps of providing a hydrostatic circuit, detecting a rapid deceleration of the vehicle, and adjusting a threshold of at least one pressure relief valve forming a portion of the hydrostatic circuit in response to the sudden deceleration. The at least one pressure relief valve facilitates quickly changing the driveline from the blended hydrostatic/mechanical power transmission mode to the hydrostatic power transmission mode. | 03-19-2015 |
