Publication number: 20140107887Abstract: In a vehicle data network with power storage and distribution systems, a ground fault detector or ground insulation monitoring device provides detection of power leakages. Integrity of the power system is reported to a body computer connected to the data network. Responsive to detection of leakage, controllers for high voltage sub-systems report out of norm power usage compared to expected power demand. The system can take corrective actions including: indicating to the operator occurrence of a ground fault; indicating the likely to the source of the fault; reconfiguring operation of the sub-system which is the likely source of the fault, including turning the sub-system off but not otherwise restricting vehicle operation; turning the sub-system off or limiting its operation after a limited time allowing the operator to configure the vehicle for restricted operation; or, placing the vehicle in a restrictive mode of operation.Type: ApplicationFiled: June 22, 2011Publication date: April 17, 2014Applicant: International Truck Intellectual Property Company, LLCInventor: Jay E.

Publication number: 20140107885Abstract: Systems and methods for monitoring health of one or more subsystems of a vehicle system are disclosed. At least one sensor can be operatively coupled to a vehicle subsystem having an operational signature and a control system is coupled to the at least one sensor. Using information provided by the at least one sensor, the control system is structured to generate a reference signature of the subsystem during a learning phase and an operational signature of the subsystem subsequent to the learning phase. Systems and methods for identifying the particular subsystem exhibiting degraded performance are also disclosed.Type: ApplicationFiled: October 12, 2012Publication date: April 17, 2014Inventors: Eric L. Hagen, Richard S. Fox, Nkemjika Ibekwe, Malcolm L. Smith

Patent number: 8700255Abstract: Systems, devices, and techniques for remotely tracking vehicle and driver behavior. Embodiments may include an on-board vehicle monitoring device, comprising an interface device and a gateway device. The interface device may include receiving information from a diagnostic system of a vehicle. The gateway device may collect a set of vehicle operating data corresponding to a driver or vehicle behavior. The set of vehicle operating data may comprise at least some of the information from the diagnostic system of the vehicle. A host computer may have instructions for compiling driver behavior data, based at least in part on analysis of received vehicle operating data. The instructions may also include instructions for providing a user interface; and instructions for causing the user interface to display, for a user, information corresponding to the compiled driver behavior data.Type: GrantFiled: October 7, 2009Date of Patent: April 15, 2014Assignee: Trimble Navigation LimitedInventor: Thomas C.

Patent number: 8700286Abstract: Embodiments relate to tire localization in tire pressure monitoring systems (TPMS). In embodiments, a TPMS includes a wheel unit and a control unit. Each wheel unit collects acceleration data and transmits that data to the control unit for processing. The control unit processes the data and, using additional data received from another vehicle system, for example an antilock braking system (ABS) or electronic stability control (ESC) system, correlates the data in order to localize each wheel unit to a particular wheel of the vehicle. Advantages include increased processing power at the control unit as compared to the wheel unit.Type: GrantFiled: December 21, 2011Date of Patent: April 15, 2014Assignee: Infineon Technologies AGInventors: Christoph Steiner, Ralf-Rainer Schledz

Patent number: 8688318Abstract: Methods, program products, hybrid, and non-hybrid vehicles are provided for providing diagnostics for a direct current (DC) converter of the hybrid, and non-hybrid vehicle. The vehicle includes an engine, a rechargeable energy storage system (RESS), the direct current (DC) converter, and a controller. The engine is automatically turned on and off based on driver inputs in accordance with an auto-stop feature. The RESS at least facilitates turning on the engine. The DC converter is coupled to the RESS. The controller is coupled to the DC converter, and is configured to determine a status of the engine, receive a DC converter voltage value from the DC converter, and provide diagnostics for the DC converter based on the engine status, RESS voltage, and the DC converter voltage.Type: GrantFiled: March 30, 2012Date of Patent: April 1, 2014Assignee: GM Global Technologies Operations LLCInventors: Jeffrey S. Richards, Daniel P. Grenn, Voytek A. Novak

Publication number: 20140088801Abstract: The present disclosure is directed to a method of monitoring the performance of a wheel brake for a wheel on a train car. The method may include detecting a first temperature of the wheel with the wheel brake deactivated. The method may also include activating the wheel brake and detecting a second temperature of the wheel with the wheel brake activated. The method may include determining a wheel brake condition based on at least the first and second temperatures of the wheel.Type: ApplicationFiled: September 27, 2012Publication date: March 27, 2014Applicant: PROGRESS RAIL SERVICES CORPORATIONInventor: MARK JOSEPH BARTONEK
