Application No. 09/094,297
9. A device for assisting and controlling a rail
vehicle of the type having a rotating wheel truck, the
device comprising:
means for sensing a horizontal distance from a
predetermined position on a facing side portion of a rail
vehicle to a location on a side portion of said wheel
truck and generating a signal relating to said distance,
said means for sensing a distance being associated with
said rail vehicle and said truck; and
means for processing said signals to determine
horizontal rotation magnitude and rotation direction of
said truck with respect to said rail vehicle.
Dierker's invention relates to a control system/method
for controlling the braking force applied to the brakes of a
towed subvehicle in an articulated vehicle system, such as the
semitrailer subvehicle in a tractor-semitrailer system, to
prevent, arrest or to minimize and quickly recover from, the
condition known as trailer brake induced trailer swing. As
shown in Figure 8, an ultrasonic transceiver 230 is mounted to
the tractor 12 and will send and receive ultrasonic signals
which bounce off predetermined surfaces on the trailer 14 to
provide an indication of the articulated vehicle articulation
angle and/or derivatives thereof. Dierker teaches that a
central processing unit 70 will, as is well known in the ABS
