Patent number: 6803530Abstract: Vehicle on-board measurement of axle load and gross combined vehicle weight is improved for an air bladder suspended vehicle by allowing for suspension hysteresis. Suspension hysteresis results in at least two distinct air pressures being possible in an air bladder for a single load. The system also reduces the disruptive effect of vehicle acceleration and deceleration on load determination. Vehicle drive train management is enhanced using the load information to effect transmission gear selection.Type: GrantFiled: March 15, 2003Date of Patent: October 12, 2004Assignee: International Truck Intellectual Property Company, LLCInventors: Kevin R. Carlstrom, Gerald L. Larson, Matthew J. Gumbel

Patent number: 6784635Abstract: A vehicle electrical system is disclosed having a plurality of electrical subsystems for supplying power to different component groups of the vehicle. A voltage regulator is provided each subsystem for setting the voltage on each electrical subsystem independently of the other electrical subsystems. One such subsystem includes a battery having a grounded terminal and an ungrounded terminal. An electrical system controller including data processing capacity provides control of the voltage level on the charging subsystem through a charging regulator having an output connected to the ungrounded terminal of the battery and a control input. An electrical power generator is connected to energize the charging regulator. Instrumentation connected to the electrical system controller provides measurements of current discharged from the battery, current delivered to the battery, and battery temperature.Type: GrantFiled: July 17, 2003Date of Patent: August 31, 2004Assignee: International Truck Intellectual Property Company, LLCInventor: Gerald L.

Publication number: 20040148932Abstract: A multi-cylinder diesel engine provides split mode operation in which one or more cylinders function as air pumps. Compressed air supplied by the cylinders is amplified and stored to a high pressure air tank from which it may be used to run air brakes or other systems. Improved energy density is achieved over prior art vehicle air systems and an auxiliary air compressor is eliminated.Type: ApplicationFiled: February 5, 2003Publication date: August 5, 2004Inventor: Gerald L.

Patent number: 6742386Abstract: An electromechanical apparatus suitable for mounting on a vehicle wheel power for generating telemetry relating to the wheel including tire temperature and pressure. The apparatus includes a pendulum mounted to rotate freely relative to the vehicle wheel which is positioned from the wheel hub. When the wheel is set to rotation, the pendulum freely hangs from the wheel hub under the influence of an off center counterweight having sufficient inertia to prevent rotation of the pendulum with the wheel. The pendulum is used to position one or more magnets to be used to excite field coils, which are mounted with respect to the wheel hub to rotate with the wheel. The magnets and rotating coils cooperate to energize a power utilization circuit also mounted with respect to the wheel hub to rotate therewith. The utilization circuit may include such sensors as desired, typically including though a tire pressure gauge and tire and wheel hub temperature gauges.Type: GrantFiled: October 30, 2000Date of Patent: June 1, 2004Assignee: International Truck Intellectual Property Company, LLCInventor: Gerald L. Larson

Publication number: 20040093931Abstract: A motor vehicle having an internal combustion engine and a lubricating oil circulation system provides estimates of the distance remaining before an oil change becomes imperative. An indirect estimate of the depletion of various additives and the deterioration of oil operating characteristics is based on engine operating variables including oil temperature, ignition timing and engine load. The limit of depletion of total base number is dynamic, since it is set against total acid number and the two figures are independently calculated.Type: ApplicationFiled: November 15, 2002Publication date: May 20, 2004Inventors: Kevin R.

Publication number: 20030205360Abstract: A vehicle energy management system relying on the principle of reallocation of existing resources provided by the vehicle manufacture. Engine belt or engine direct driven components are replaced with electrical motors. Since replacement of the main fan unit would involve a prohibitively large fan due to starting currents, the larger component that would have multiple cooling purposes is replaced with smaller single function electrical components. The larger multipurpose heat exchangers such as the vehicle radiator are replaced with smaller single function heat exchangers associated with the smaller electric fans. The energy management system may involve a main vehicle engine crankshaft mounted generator. This simple generator creates high voltage DC electricity that may be converted to household level AC for the operation of customer application equipment.Type: ApplicationFiled: May 1, 2003Publication date: November 6, 2003Inventor: Gerald L.

Patent number: 6642403Abstract: This invention relates to a series of fluoroalkylsilane compounds of formula I. These compounds are silylation reagents which enhance the solubility of the silylated products in fluorocarbon solvents for preferred use in fluorous phase synthesis. Use of these compounds protects fragile hydrogen groups and also provides for the straightforward separation of the ultimate reaction products though fluorous phase extraction. This invention also relates to a two-step process for making compounds of formula I. The process comprises reacting an alkyldialkoxysilane with a perfluoroalkyl-substituted silane to produce a perfluoroalkyl-substituted dialkylsiloxyalkylsilane intermediate; and reacting the intermediate with halogen.Type: GrantFiled: November 6, 2002Date of Patent: November 4, 2003Assignee: Gelest, Inc.Inventors: Barry C.

Patent number: 6513368Abstract: A method for generating indicators relating to the condition of lubricating oil in an internal combustion engine. A set of variables relating to operation of the internal combustion engine serve as proxy variables for brake mean effective pressure developed by the internal combustion engine. Operation of an engine is monitored to develop values for the proxy variables. Soot being added to the lubricating oil from the developed values and accumulated to provide an estimate of total soot in the lubricating oil. Lubricating oil temperature is periodically monitored and a history of the lubricating oil temperature measurements is kept to allow generation therefrom of an estimate of shear of the lubricating oil. Accumulated estimate of soot is kept as a distance remaining until the lubricating oil becomes unsuitable for continued use in the internal combustion engine. Similarly, estimated shear is expressed as a distance until the lubricating oil is to be replaced.Type: GrantFiled: June 28, 2002Date of Patent: February 4, 2003Assignee: International Truck Intellectual Property Company, L.L.C.Inventors: Frank Bondarowicz, Kevin R Calstrom, Gerald L Larson
