  • Patent number: 8798854
    Abstract: A data recorder mounted to a vehicle is disclosed. When detecting a specific behavior of the vehicle, the data recorder determines whether or not a presently-occurring failure detected by a failure detector of the vehicle is a cause of occurrence of the specific behavior. When the presently-occurring failure is not the cause of occurrence of the specific behavior, the data recorder is permitted to record a control data in a non-volatile data storage device. When the presently-occurring failure is the cause of occurrence of the specific behavior, the record processing device is prohibited from recording the control data in the non-volatile data storage device.

  • Publication number: 20140144819
    Abstract: A process, system, and component configuration are described that discourages customer acceptance/use of will-fit, reconditioned, and counterfeit product components, by determining whether or not a serviceable product component is genuine. If a component is determined to not be genuine, then appropriate action may be taken to warn operators and document such findings. For example, one or more markers are disposed or otherwise put on the subject serviceable product component and serves as a targeted feature, and/or a particular characteristic of the filter itself is identified as the targeted feature. A sensor is used to detect the targeted feature and obtain information unique to the serviceable product component. The targeted feature(s) identifies the particular serviceable component as genuine and forms the basis for determining whether a genuine component has been installed. In some circumstances, a fluid filter product is the component that is the subject detection.

  • Patent number: 8676434
    Abstract: A vehicle includes electrical components, current sensors which determine current flowing through the electrical components, and a control system. The control system calculates and records error index values over an interval using the currents. The control system increments a first counter with every sample in the series, increments a second counter whenever a given error index value exceeds a calibrated high threshold, and decrements the second counter whenever the given error index value is less than a calibrated low threshold. A control action, e.g., recording a PASS or FAIL value, executes when either the absolute value of the second counter or the present value of the first counter reaches a corresponding limit or threshold. A method enhances the robustness of a hybrid vehicle torque security diagnostic using the control system. The vehicle and method use a signed X of Y debouncing or error signal processing method as noted above.

  • Patent number: 8634985
    Abstract: A method of detecting an in-range failure of a brake pedal position sensor includes calculating the difference between a minimum position and a maximum position of the brake pedal position sensor. The calculated difference is weighted to define a fast test weighted input value and/or a full test weighted input value. A cumulative test result value is incremented by the fast test weighted input value and/or the full test weighted input value. The cumulative test result value is filtered to define a moving average of the cumulative test result value after each incremented occurrence. The moving average of the cumulative test result value is tracked to determine if the brake pedal position sensor is functioning properly.

  • Patent number: 8565949
    Abstract: A method includes determining an amount of power currently available from a battery for tractive torque as an amount of power stored in the battery less an amount of power required to power other vehicle components, and less an amount of power required to start the engine. An output torque limit when torque is provided only by the motor and power required to provide the output torque limit are determined based on test data. A maximum output torque is calculated by multiplying the amount of power determined to be currently available for tractive torque by a ratio of the output torque limit to the amount of power required to provide the output torque limit. The current output torque may be reduced at a predetermined rate until within a predetermined range of the lesser of the maximum output torque and the output torque limit if an engine start is requested.

  • Patent number: 8509985
    Abstract: A method is provided for identifying a root cause of a fault in a serviced vehicle based on analytical symptoms. Parameter identification data associated with identified DTCs is retrieved. Parameter identification data from a plurality of vehicles experiencing the DTCs is collected. A first set of diagnostic rules is generated that identify vehicle operating parameters for executing a DTC algorithm or for triggering a DTC. A second set of diagnostic rules is generated that identify vehicle operating parameters used for selecting field failure data obtained when the DTC is triggered. Statistically significant rules are extracted from the second set of diagnostic rules. The first set of rules and the statistically significant rules are cooperatively applied to the parameter identification data for identifying a subset of the parameter identification data that represents anomalies. A subject matter expert analyzes the anomalies for identifying a root cause of the fault.

  • Patent number: 8494708
    Abstract: A controller for determining whether a previously-detected vehicle malfunction still exists. If the malfunction is no longer detected in the sensor signals, a vehicle control system operates in a first operational state or normal operational state with respect to the previously-malfunctioning sensor (e.g., signals from the sensor are used to control the vehicle). If the malfunction continues to be detected, the vehicle control system operates in a second operational state or malfunction state with respect to the malfunctioning sensor in which the signals from the sensor are not used to control the vehicle.

  • Patent number: 8494706
    Abstract: The system and method for determining the operational condition of an electric fuel pump (16). The test apparatus (22) is configured to perform first, second and third tests. During the first test, a low voltage, low current signal is applied to produce an inductive reflectance from the pump armature winding. During the second test, continuity is assessed in the coil winding circuit. During the third test, a higher power, short duration pulse is applied to create rotational movement of the pump armature for the purpose of detecting mechanical and/or electrical issues not otherwise discerned from the prior tests. An optional fourth test may be conducted in which the pump (16) is run for a short period of time at standard operating power to generate a current waveform. Collected test data is compared to stored reference data sets using a processor contained within the test apparatus (22). If collected test data corresponds within an acceptable threshold range to the reference data, a PASS signal is generated.

  • Patent number: 8467929
    Abstract: A controller for determining whether a previously-detected vehicle wheel speed sensor malfunction still exists. The controller includes an electronic, non-volatile memory, and an electronic processing unit connected to the electronic, non-volatile memory. The electronic processing module includes a malfunction monitoring module, a failure handling module, and a signal checking module. The malfunction monitoring module monitors the operation of at least one wheel speed sensor and generates a fault signal when the at least one sensor malfunctions. The failure handling module causes drive cycle information and the fault information to be stored in the electronic, non-volatile memory. The signal checking module performs a signal check on information from the at least one wheel speed sensor. A tell-tale indicator is deactivated and/or a vehicle control system resumes normal operation if the wheel speed sensor passes the signal check.
