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.

摘要： Systems and methods allow for the accurate determination of the terrestrial position of an autonomous vehicle in real time. A first position estimate of the vehicle 102 is derived from satellites of a global positioning system and/or a pseudolite(s). The pseudolite(s) may be used exclusively when the satellites are not in the view of the vehicle. A second position estimate is derived from an inertial reference unit and/or a vehicle odometer. The first and second position estimates are combined and filtered using novel techniques to derive a more accurate third position estimate of the vehicle's position. Accordingly, accurate autonomous navigation of the vehicle can be effectuated using the third position estimate.

摘要： A differential system and method for computing the position of a mobile receiver at or near the surface of the Earth using a base receiver having a known position and using a satellite-based navigation system including a constellation of navigation satellites is disclosed. The method includes the following steps. A base position estimate is computed for the base receiver using a pseudorange from a first satellite and ranges from two other satellites. A first vector difference between the base position estimate and the known position of the base receiver is computed. An initial position estimate is computed for the mobile receiver. A refined position estimate is computed for the mobile receiver using a pseudorange from the first satellite and ranges from two other satellites. A second vector difference between the initial position estimate and the refined position estimate of the mobile receiver is computed. Finally, a third vector difference between the first vector difference and the second vector difference is computed. The position of the first receiver is precisely computed by adding the third vector difference to the initial position estimate for the mobile receiver.

摘要： An apparatus determines the payload carried in a work vehicle by monitoring the pressure of a fluid contained within front and rear suspension struts. The struts are connected in supporting relation between a load carrying portion and a ground engaging portion of the work vehicle such that a compression condition of the strut is detected while the work vehicle is in motion. Moreover, a pressure differential corresponding to the compression condition is indicative of the magnitude of the payload supported by the strut.
