  • Patent number: 10589763
    Abstract: A method of determining the actual position of a track relative to a fixed point located in a lateral vicinity of the track by using a registering device being mobile on the track includes surveying the position of the fixed point relative to the track. The registering device is moved along the track, image pairs of the lateral vicinity of the track are continuously recorded by a stereo camera system on the registering device and the fixed point is searched for in the image pairs by pattern recognition carried out in an evaluation device. Upon recognition of the fixed point, the position of the fixed point relative to the track is determined by evaluating at least one image pair. This creates the possibility of surveying fixed points in passing with the configuration of the fixed point not being bound to any special form. A measuring system is also provided.

    Abstract: A computer-implemented method, computerized apparatus and computer program product. The method includes receiving at a computing device, a Sweeney-Robertson-Tocher (SRT) implementation, and a look-up table (LUT) used by the SRT implementation; obtaining an assertion for the SRT, the assertion associated with at least one entry from the LUT; verifying the assertion by executing a formal verification engine on the SRT implementation. Subject to the assertion failing, the method further provides a counter example for a computation that when performed by the SRT implementation accesses the at least one entry. Further, subject to the assertion holding, the method performs determining that the at least one entry is unreachable.

  • Patent number: 10364552
    Abstract: An excavator calibration framework comprises an excavator, a laser distance meter (LDM), and a laser reflector. The excavator comprises a linkage assembly (LA), implement, and controller. The LA comprises a boom with point B, stick coupled to point B, and four-bar linkage (4BL) including nodes D, F, G, and H (a dogbone linkage between nodes D and F). The laser reflector is disposed at node F. The nodes F, G, and the point B define an outer triangle BGF that defines with node D three inner triangles DGB, DBF, and DFG. The controller executes an iterative process including determining a node F position based on a LDM/laser reflector measurement signal, determining a node D position based on the node F position, and determining a dogbone angle BDF of DBF based on the node D position. The controller generates an actual dogbone angle based on a series of dogbone angles.

  • Patent number: 8738256
    Abstract: A method of determining a torque transfer touch point of a clutch within a drive train includes applying a predetermined amount of current to an electric motor such that the electric motor will apply a torque to at least a portion of a clutch. The predetermined amount of current will not rotate a shaft of the motor when the clutch is at least partially engaged. The method also includes initiating disengagement of the clutch, detecting movement of at least a portion of the motor, and recording a clutch parameter that is generally coincident with the detecting movement of a least a portion of the motor.

  • Patent number: 8731769
    Abstract: An inertial sensor calibration method has steps of mounting an observer device and an inertial sensor of a vehicle carrying on an inertial move, acquiring actual vehicle motion data from the observer device and inertial signal data of the inertial sensor, calculating an integral corresponding to the vehicular dynamic variation model with respect to the inertial signal data to obtain predicted vehicle sensor data and calculating variations of the actual vehicle motion data, acquiring differences between the two calculated data, applying an energy optimization and a discretization to the differences so as to obtain parametric error variances, and feeding back the parametric error variances to the vehicular dynamic variation model to calibrate the parameters associated with offset and scale factor and acquire a calibrated vehicular dynamic variation model. Under the premise of no GPS, electronic compass or pressure sensor, the present invention can secure positioning continuity and reliability.

  • Patent number: 8718863
    Abstract: A method for judging the drivability of vehicles including acquiring drivability-relevant physical data during the driving operation of the vehicle; checking the data for the presence of trigger conditions which indicate the existence of specific driving states; if a specific driving state exists, calculating at least one local evaluation, which is a judgment of an evaluation criterion relevant for the driving state; and calculating an overall evaluation for the acquired driving state. An increase in precision may be achieved with repeated occurrence of identical driving states, a correction variable is calculated for the evaluations, which is a function of the differences in the behavior of the vehicle upon identical driving states, and a corrected evaluation is calculated in which this correction variable is taken into consideration.

  • Patent number: 8662744
    Abstract: A method of calibrating a position sensor in an automotive transmission having a transmission housing having mounted therein a casing (10) for the position sensor which includes a pressure member (14) movably supported in the casing (10), and an electrical displacement sensor (38) actuated by the pressure member (14) for measuring the position of the pressure member (14) relative to the casing (10), such that, after the casing (10) of the position sensor has been mounted in the transmission housing, the displacement sensor (38) is used for performing at least one calibration measurement for at least one gear position, and, for each gear position to be detected, a tolerance range for the corresponding measurement value of the displacement sensor is defined on the basis of the result of the calibration measurement.

  • Publication number: 20140039750
    Abstract: Temperature compensation for ultrasonic sensors can have a significant error that is highly undesirable because temperature of ultrasonic sensors and the temperature of the medium through which they sense objects affect signal strength calibrations (e.g., echo thresholds) applied when detecting an object. In order to increase the detection capabilities and reported distance of an object, ultrasonic sensors need to adjust their detection criteria and distance calculations as the temperature of air surrounding a vehicle (i.e., outside air temperature) changes and also as the temperature of the sensor changes. Embodiments of the inventive subject matter provide for a simple, effective and consistent approach for determining a temperature upon which such detection criteria and distance calculation adjustments can be based.

    Abstract: A sensor characteristic correction device is configured to detect a characteristic of a first sensor arranged upstream of a catalyst 6 in an exhaust passage 4 of an internal combustion engine 2, and a characteristic of a second sensor that is an air-fuel sensor 12 arranged downstream of the catalyst 6, to calculate a first air-fuel ratio based on the characteristic of the first sensor, and calculates a second air-fuel ratio based on the characteristic of the second sensor, to detect, when the catalyst 6 is in an inactive state after start-up of the internal combustion engine 2, a difference between the first characteristic and the second characteristic or a difference between the first air-fuel ratio and the second air-fuel ratio, and to correct the responsiveness of the first or the second sensor in accordance with the difference.

  • Patent number: 8612091
    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.
