  • Patent number: 9120375
    Abstract: Embodiments relate to a pedal module including an accelerator pedal; a pedal sensing unit; a pedal monitoring unit; and a control unit. The pedal monitoring unit determines whether an accelerating state of a vehicle is in an abnormal sudden acceleration state using abnormal sudden acceleration determination information transmitted from the pedal sensing unit, and transmits an accelerator pedal output signal to the control unit. The accelerator pedal output signal is based on the rotation angle of the accelerator pedal when the accelerating state of the vehicle is not in the abnormal sudden accelerating state. The accelerator pedal output signal is a controlled accelerator pedal output signal when the accelerating state of the vehicle is in the abnormal sudden accelerating state. The control unit controls the vehicle according to the accelerator pedal output signal. The abnormal sudden acceleration determination information includes information on the force applied to the accelerator pedal.

    Abstract: A system and method for detecting and isolating faults in pressure ports (2) and pressure transducers (3) of a pressure sensing system are disclosed. The system comprises a set of pressure ports (2) flushed to a nose cap (1) of a space vehicle in crucifix form. Three pressure transducers (3) are connected to each pressure port (2) through pneumatic tubes (4) for measuring surface pressure from the pressure ports (2). Separate power supplying units (7, 8, 9) are connected to the three pressure transducers (3) for powering the pressure transducers (3) at each pressure port (2). A processing unit (10) is configured to acquire voltage inputs corresponding to the measured surface pressure from the pressure transducers (3). The processing unit (10) executes one or more levels of fault checking to detect and isolate pressure transducer failures and blockage of the pressure ports (2) based on the voltage inputs.

  • Patent number: 8948996
    Abstract: Vehicle operations data is received from a plurality of data capturing devices installed at a plurality of transport vehicles. The vehicle operations data is representative of sensor output captured by the data capturing devices. Data sets are processed to obtain different vehicle safety metrics defined by the different types of sensors. An indication of non-conformance can be output when a compared vehicle safety metric does not conform to a threshold. Vehicle safety metrics can be combined into a combined representation of a categorical aspect of vehicle safety, which can be dynamically updated whenever a metric is added or removed. Combined representations can be filtered or grouped according to a reporting criterion to generate reports for drivers, units, company divisions, and the like. Vehicle operations data can be converted from multiple different formats used by different data sources to a common format used for processing metrics and combined representations.

  • Patent number: 8823400
    Abstract: A diagnostic method and system is described for diagnosing an operating condition of a conductive particulate matter sensor. The sensor has a substrate with electrical resistance that varies with temperature and two electrodes on the substrate adapted to collect particulate matter between the electrodes, thereby establishing an electrically conductive path through collected particulate matter between the electrodes that can be detected by measuring electrical resistance between the electrodes, Relect. The diagnosis is performed by heating the substrate in the area between the electrodes and using the resistance between the electrodes to determine detecting whether contamination is present on the surface of the sensor. Heat may be maintained on the sensor to attempt to burn off a detected contaminant, and a subsequent resistance reading may be used to determine if the contaminant was successfully burned off.

    Abstract: An analysis tool which extracts all the available parameter identifications (i.e. PIDS) from a vehicle's power train control module for diagnostic decisions. This is done by checking these PIDS and other information (e.g., calculated PIDS, Break Points, charts and algorithms) in three states; key on engine off, key on engine cranking, key on engine running. In all three modes the tool is comparing the live data from PIDS and voltage to the other information (e.g, Break Points). If any of this data are outside the programmed values a flag is assigned to the failure or control problem. The relationship between a particular PID and its associated preprogrammed value(s) may be indicated by a light. The depth of the problem (if any) is conveyed by the color of the light. Also included are tests/charts for fuel trim, engine volumetric efficiency, simulated injector, power, catalyst efficiency, and engine coolant range.

  • Patent number: 8230716
    Abstract: A diagnostic method and system is described for diagnosing an operating condition of a conductive particulate matter sensor. The sensor has a substrate and two electrodes on the substrate adapted to collect particulate matter between the electrodes, thereby establishing an electrically conductive path through collected particulate matter between the electrodes that can be detected by measuring electrical resistance between the electrodes, Relect. The diagnosis is performed by detecting whether water vapor condensate may be present between the electrodes and if it is, then measuring resistance between the electrodes while subjecting the sensor to conditions sufficient to evaporate any water vapor condensate and diagnosing a validation that the sensor is in proper operating condition if resistance increases in a manner consistent with evaporation of condensate.

  • Patent number: 8234035
    Abstract: An in-vehicle electronic control apparatus includes a monitoring control circuit configured such that a monitoring control circuit unit transmits question information; a main control circuit unit transmits answer information generated by a microprocessor; the monitoring control circuit unit applies an addition and subtraction correction to a value of a first present-value memory in response to a result of a comparison between correct-solution information stored in a data memory and the answer information; and when the accumulated present value exceeds an abnormality determination threshold value, the monitoring control circuit unit generates a first abnormality detection signal so as to initialize and restart the microprocessor, and variably sets the abnormality determination threshold value or an abnormality determination time, based on selectively applied setting constants generated with pattern switches.

  • Patent number: 8150575
    Abstract: A method for plausibilizing sensor signals of a vehicle system, the sensor signals being monitored with regard to compliance with one plausibility criterion or a plurality of plausibility criteria with the aid of a plausibilization algorithm. The function of the vehicle system is able to be maintained even in critical driving situations, in particular following a collision, if the driving status of the vehicle is monitored with regard to a collision and the plausibilization algorithm is modified if a collision was detected.
