    摘要: A device for detecting undesirable vibrations in a vehicle drive line utilizes a sensor that communicates with a controller to indicate undesirable vibrations in a drive line component. In one example, a temperature sensor is placed in a central portion of a universal joint. The temperature sensor preferably is supported within a single housing along with a transmitter that is responsive to the temperature sensor to transmit a signal to a remotely located receiver without using a hardwire connection between the transmitter and receiver. Packaging the temperature sensor, transmitter and a power source within a single housing provides the ability to seal off or close a series of lubrication channels that extend through the universal joint. In another example, a contact-based sensor provides a signal whenever a vibration of a drive line component occurs. The contact-based sensor signal preferably is processed to monitor the number of vibrations over time and a vehicle operator is provided with an indication of the level of vibrations as desired.

    摘要: A method to estimate the thickness of a brake lining based on the periodic sampling of the output of a temperature sensor embedded in the brake lining. A temperature histogram is created which is compared to calibration histograms stored in an electronic processing unit to yield an estimated brake lining thickness which is transmitted to the vehicle cab or to another on-board electronics unit. A brake wear factor is calculated from the temperature histogram by multiplying the average value of each temperature range by the frequency of occurrence and then summing the results.

    摘要: The position of a satellite in a satellite based navigation system is determined without reliance on satellite ephemeris data. Orbital parameters are computed for each satellite. The orbital parameters can then be used to predict the position of each satellite at any time. Subsequent ephemeris data may be compared to a predicted satellite position to determine whether the ephemeris data is corrupt. The orbital parameters may be determined by: computing a pseudorange and a velocity for a selected satellite for a plurality of times, computing at least three estimated positions of the satellite from the pseudoranges and velocities, and computing orbital parameters for the satellite from the three estimated positions. In another embodiment, the orbital parameters are determined by: determining the position of a receiver for at least three times using a constellation of satellites, using the three receiver positions to triangulate on an average position for the selected satellite in the constellation, repeating these steps until at least three mean satellite positions have been computed, computing the orbital parameters from the three mean positions of the selected satellite.

    摘要: A dynamic payload monitor measures and displays payload weight for a loader vehicle operated on a slope by sensing the hydraulic pressure and position of the lift arm cylinders. The payload weight is computed by curve fitting the sensed cylinder pressure and position data to a second order polynomial, and then performing interpolation or extrapolation with a pair of pressure versus position reference parabolas obtained during calibration. Payload weight is corrected for errors caused by operating the loader vehicle on a slope. The weight computation algorithms used in the dynamic payload monitor are applicable to a number of work vehicles having at least one work implement linkage and at least one hydraulic cylinder for modifying the linkage geometry.

    摘要: A sensor system includes a housing that houses a thermally sensitive sensor, a transmitter portion and a power source. Preferably, the sensor device is encapsulated to protect the components from the environment. The transmitter generates a signal in response to the sensor detecting a temperature in a vehicle component that exceeds a predetermined temperature. A receiver is located remotely from the transmitter to receive the signal. The power supply generates electricity when the temperature of the vehicle component achieves an initial threshold temperature that is less than the predetermined temperature.

    摘要: A passive RF tag receives a number of varying inputs. The RF tag is preferably associated with a vehicle, and the inputs are indicative of diagnostic information from a vehicle braking system. The passive RF tag receives a signal from a transmitter that causes the RF tag to query the current status of the several inputs. The RF tag then sends a signal back to the transmitter/receiver indicative of the current status.

    摘要: A vehicle braking system includes a device for cooling the components of the brake assembly. The air source that is normally used to activate the brake assembly components is coupled with a plurality of flexible conduits that direct air toward one or more of the brake assembly components. A high velocity air nozzle preferably is provided at the end of each conduit. The air from the compressed air source is maintained in a compressed state through the conduits and decompresses as it exits the discharge nozzles. The decompression of the air through the nozzles results in cooling the air and the nearby brake components at which the air is directed.

    摘要: A roll-over detector for vehicles includes a first accelerometer mounted on a first axle of the vehicle, a second accelerometer mounted on a second axle of the vehicle, and a third accelerometer mounted on a third axle of the vehicle. A controller compares data received from the first and second accelerometers and actuates a safety device to prevent a roll-over condition if the differences between the data exceed a predetermined value. The controller utilizes data from the third accelerometer to account for the effect of road conditions on the variations between the data from the first and second accelerometers.

    摘要: A brake lining wear indicator utilizes a temperature sensor assembly embedded in a brake lining of a drum brake assembly. The temperature sensor assembly includes two temperature sensors with a first temperature sensor located at a first distance X from the wear surface of the brake lining and a second temperature sensor located at a second distance X+d from the wear surface. A timing device measures the time period for the first temperature sensor to reach a first predetermined temperature and measures the time period for the second temperature sensor to reach a second predetermined temperature. The remaining useful thickness of the brake lining is determined based on the ratio of the respective time periods. Thus, the indicator provides a time-temperature based determination of when the brake linings should be replaced. This determination is easily monitored during the operation of the vehicle and can be made without requiring a physical measurement or visual inspection of the thickness of the brake lining on each brake shoe.
