    Abstract: A vehicle system and method that can determine object sensor misalignment while a host vehicle is being driven, and can do so without requiring multiple sensors with overlapping fields-of-view. In an exemplary embodiment where the host vehicle is traveling in generally a straight line, the present method uses an object sensor to track the path of a stationary object as it moves through the sensor's field-of-view and compares the sensed object path to an expected object pat*h. If the sensed and expected paths of the stationary object deviate by more than some amount, then the method determines that the object sensor is skewed or otherwise misaligned.

    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.

  • Publication number: 20130218398
    Abstract: A vehicle system and method that can determine object sensor misalignment while a host vehicle is being driven, and can do so without requiring multiple sensors with overlapping fields-of-view. In an exemplary embodiment where the host vehicle is traveling in generally a straight line, the present method uses an object sensor to track the path of a stationary object as it moves through the sensor's field-of-view and compares the sensed object path to an expected object path. If the sensed and expected paths of the stationary object deviate by more than some amount, then the method determines that the object sensor is skewed or otherwise misaligned.

  • 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: 8489270
    Abstract: The invention relates to a method and corresponding device for diagnosing the dynamics of an exhaust gas sensor, which is disposed in an exhaust gas duct of an internal combustion engine in the direction of flow of the exhaust gas upstream or downstream of a catalytic converter and with which the air/fuel ratio of the gas mixture supplied to the internal combustion engine is controlled via a control circuit. During diagnosis, provision is made for at least one actuator intervention to be specified by means of a control algorithm of a diagnostic controller specifically m the direction of an asymmetric behavior, which is achieved by an extension of one of the two ramps, until the actuator intervention is compensated by an asymmetric dynamic error of the exhaust gas sensor, a reaction to said actuator intervention being used as criterion for assessing an asymmetric dynamic error of said exhaust gas sensor.

  • Patent number: 8463486
    Abstract: A system for identifying an object impacting a vehicle bumper during a collision. The system receives acceleration values from each of a plurality of sensors and calculates a center strength value based on the acceleration values. The center strength value is indicative of the amount of force that is applied to the center of the vehicle bumper. The system then determines a preliminary impact location on the vehicle bumper based at least in part on the acceleration values. A normalized intrusion value is calculated based on the center strength value, the impact location, and a bumper stiffness factor. The bumper stiffness factor is indicative of the stiffness of the bumper at the impact location. The system then identifies the object impacting the vehicle bumper based at least in part on the normalized intrusion value.

  • Patent number: 8457833
    Abstract: An apparatus is provided for diagnosing the state of health of a vehicle and for providing the operator of the vehicle with a substantially real-time indication of the efficiency of the vehicle in performing an assigned task with respect to a predetermined goal. A processor on-board the vehicle monitors sensors that provide information regarding the state of health of the vehicle and the amount of work the vehicle has done. In response to anomalies in the data from the sensors, the processor records information that describes events leading up to the occurrence of the anomaly for later analysis that can be used to diagnose the cause of the anomaly. The sensors are also used to prompt the operator of the vehicle to operate the vehicle at optimum efficiency.

    Abstract: A system and method of monitoring oil consumption in a gas turbine engine system are provided. When the gas turbine engine is not running the reservoir oil level, reservoir oil temperature, and reservoir attitude are sensed. The current gas turbine engine system oil quantity is determined based on at least the sensed reservoir oil level, the sensed reservoir oil temperature, and the sensed reservoir attitude. When a predetermined event has occurred, an average gas turbine engine system oil quantity is automatically calculated. The gas turbine engine system oil consumption rate is determined from a plurality of the average oil quantities.

  • Publication number: 20130054083
    Abstract: A system for a vehicle includes an oxygen storage capacity (OSC) determination module, a delay determination module, a correction module, and a fault detection module. The OSC determination module determines an OSC period of a catalyst of an exhaust system based on first and second amounts of oxygen measured using first and second oxygen sensors located upstream and downstream of the catalyst, respectively. The delay determination module determines a delay period of the second oxygen sensor. The correction module sets a corrected OSC period for the catalyst based on a difference between the OSC period and the delay period. The fault detection module selectively indicates that a fault is present in the catalyst based on the corrected OSC period.
