Abstract

Instruments used to determine the vehicle's position relative to the locator are incorporated with the energy coils to emit a magnetic field collected from the magnetic flux line extending radius from the end of the longitudinal shaft. Of the detector coils installed on the vehicle The motor consists of four proofing coils. Each of these responds to the frequency of the detecting device's magnetic field, and each proofing coil has a large shaft, with these detecting coils supported in two pairs. The large shaft of each pair of detector coils appears on either side of the common central plane and extends parallel to the central plane. Location pointing device Each pair of detector coils is arranged in an X pattern with large shafts across, perpendicular to each other, to be centered on each pair of coils. These two coils Will be installed with zero Mid-distance from each other with a constant distance on the line The base has a large shaft of the coil at a 45 degree angle. The detector wire is processed to produce X and Y coordinates as well as the relative position of the detector to the Location pointing device The pointing device may be induced induced by the antenna on the vehicle.

Claims (19)

1. The instrument used to determine the position of the vehicle relative to a fixed positioning device will have a positioning device consisting of a coil with a central longitudinal shaft and an excitation carrier that causes the coil to emit a magnetic field at a specific frequency. This field then concentrates magnetic flux lines to extend radially outwards from the end of the longitudinal shaft. This instrument will have a sensor mounted on the vehicle. This sensor will consist of four detection coils, each responding to a magnetic field frequency, and each having a main shaft attached. The sensor will have two pairs of carriers supporting the detection coils, with main shafts appearing in two parallel planes at the designated position on the vehicle, extending diagonally to the longitudinal shaft of the positioning device. The main shaft of one pair of detection coils will be positioned in one plane, and the main shaft of the other pair of detection coils will be positioned in another plane. The detectors of each pair are arranged in an X-shape, with one main shaft of each pair of coils extending perpendicularly to the main shaft of the other pair of coils. These main shafts of each pair transverse along their length to define the centers of each pair of detector coils. The centers of each pair of detector coils are separated by a constant distance along the baseline. This baseline is transversely positioned at a 45-degree angle between the main shafts of each detector coil. The circuit carriers used to receive the position signal from each detector coil respond to the path to the magnetic field, and the carriers are used to calculate the position signal and the angular relationship between the detector coils (Y) and the coordinates (X) that specify the position of the detector assembly relative to the pointer. 2.

A sensor assembly modified for mounting on a vehicle to detect the vehicle's position relative to a fixed position indicator (FPI). This sensor assembly consists of two pairs of sensor coils. Each sensor coil has a longitudinal shaft. Each pair of sensor coils is arranged in an X-shape, with the longitudinal shafts perpendicular to each other to serve as the centers for each pair of sensor coils. The carriers supporting the two pairs of sensor coils are centered separately by a corresponding distance along the baseline, with the longitudinal shafts of each sensor coil perpendicular at a 45-degree angle, and the longitudinal shafts of each pair of sensor coils are positioned on opposite sides and extend parallel to the common central plane. Circuit carriers are connected to each sensor coil to receive position signals, and carriers receive position signals and the corresponding fixed X and Y coordinates specifying the vehicle's position. 16.
