FIG.
GUIDING SYSTEM FOR A COMPUTER CONTROLLED VEHICLE BACKGROUND OF THE INVENTION This invention relates to a guiding system for a computer controlled vehicle along a selected path within a traffic network.
Many methods have been proposed for utilization of the computer as a means for controlling vehicular mass transportation in a traffic network. Several such schemes were disclosed in the International Fair held in Japan in 1970.
These traffic networks would provide for a plurality of vehicles all controlled by means of a computer so that each vehicle would follow a selected path so as to reach a desired point in a minimum period of time. In these methods, the vehicle must select the correct path within the traffic network without any malfunction. Such networks require provision of a simplified computer control logic and selecting mechanism to enable quick switching of a vehicle from one track or guideway to another.
In railways, monorails, and the like, the tracks themselves are moved by a switch to transfer the vehicle from one track to another. In a mass transit system, the mass of moving track portions would be considerable. Therefore, there exists a need for a substitute for conventional rail switches.
SUMMARY OF THE INVENTION The features of the present invention include a flat track surface and a guide channel, under the surface thereof, having a rectangular cross section and transversing the length of the track. The bottom of the guide channel is provided with a guide reference means which may be one of a variety of forms. Another feature of the invention is the provision of a steering guide link on the vehicle, the steering linkage having two lower crank portions off-set or staggered with respect to the axis of the link'proper, and carrying two guide wheels mounted on the respective crank positions. Accordingly, the two guide wheels are also positioned in an off-set or staggered relationship. The crank portions carrying the guide wheels are on the lower end of the steering guide link which extends through a slit in the track surface and into the guide channel. The two guide wheels contact the two vertical inner walls of the guide channel, thereby causing the wheels to follow the guide channel. The slit is defined by ribs extending from the upper edges of the channel inwardly. The guide link is further equipped with a guide follower means which is adapted to engage the guide reference means for the purpose of selection of a path at a branch or junction. The manner in which the guide follower means engages the guide reference means is controlled by means of a computer. In other words, the computer governs the manner in which the guide follower means engages the guide reference means, which means governs the guide wheels and steering guide link. The steering guide link, in turn, is operatively connected to the steering mechanism of the vehicle, so that the vehicle will follow the desired path or track.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 to 4 show one embodiment of the present invention. A vehicle I is shown as traveling on surface 3 of a transportation module track 2. The vehicle 1 has a steering guide link 4 extending downwardly from the vehicle I through a slit 5 in track surface 3 and into a guide channel 7. Slit 5 is coextensive with the length of track 2 and is defined by ribs 3' and 3" of surface 3.
As shown in FIG. 2, the lower portion of the steering guide link 4 is of a double crank shape and carries two guide wheels 6 and 6' which are arranged horizontally and in contact with the vertical inner walls 7' and 7", respectively, of the guide channel 7. Thus, the two guide wheels 6 and 6' are off-set, or staggered vertically within the guide channel 7 and are guided by the latter. The lower end of steering guide link 4, below the guide wheels 6 and 6, has a flat U-shaped guide follower 27 attached thereto by means of a toggle linkage 26. Guide follower 27 follows the path defined by guide rail 25.
The steering guide link 4 is operatively connected with the steering mechanism of the supporting wheels 10 of the vehicle 1 and thus governs the steering angle of the supporting wheels 10 in accordance with the position of the guide follower means 27.
The guide follower means 27 is normally spaced from or above the bottom surface 9 of the guide channel 7 as when the vehicle follows the linear track.
As indicated in FIGS. 2 through 4, located in the center of, and on the bottom of, the guide channel 7 is a rail or guide reference means 25 having a given width (a) and a given height (h). Rail 25' branches from guide rail 25, as shown in FIG. 3.
The leg portions 28 and 28' of the guide follower means 27 are designed to selectively contact either side 29 or side 29' of a rail 25 or 25' and to slide along the selected side of the rail. The selecting means (not shown) which controls the toggle mechanism 26 is mounted on vehicle 1 and is remotely controlled by means of a computer. Thus, when the vehicle 1 travels linearly, in the direction indicated by arrow A, the leg portion 28 will keep sliding along the left side 29 of the rail 25. The flat U-shaped guide follower means 27 will remain biased by spring action against side 29 until another signal is received from the computer.
If the vehicle 1 is to leave track 25 and follow branch track 25, in the direction indicated by arrow B as shown in FIG. 3, the toggle means 26 is operated, responsive to a computer signal, so as to cause the leg 28' to slide along the right side 29' of the rail 25.
As shown in FIG. 4, if the leg 28' of the follower means 27 after transfer to the branch track 25' continues in contact with the right side 29' of the rail 25 as viewed in the direction of arrow B, then the leg 28' will catch at the point where rails 25' and 25" intersect, resulting in breakage. Accordingly, there is provided a sloped member 35 on the right side 29' of the rail 25' to restore the guide follower means 27 to the normal or neutral position, i.e., with leg 28 in contact with left side 29 of the rail.
On the other hand, if the vehicle is traveling toward the joining point of the tracks in the direction indicated by arrow C of FIG. 4, the leg 28 of the guide follower means 27 is slidingly in contact with the left side of the rail 25". Therefore, if the leg keeps in contact with the left side of the rail 25 at the joining point of the rails 25' and 25", the leg 28 will be broken. To avoid this, there is provided a sloped means downstream of the junction point which serves to lift the leg 28 and cause the right let 28' to contact the right side of the rail 25". After passing the junction point of the tracks, the leg portion 28 is restored to the normal position by another sloped means 37 on the right side of the rail 25" to lift leg 28' into the normal position.
FIGS. through 8, show a second embodiment of the invention. A vehicle 101 is shown on the surface 103 of transportation module track 102 similar to that shown in FIG. 1. A steering guide link 105 and guide wheels 106 and 106' are provided similar to those of the first described embodiment of the invention, except for an extension or contacting element 112 affixed to the lower end of the steering guide link 105. In this case, the contacting element may assume the form of a round bar or of a flat bar. The steering guide link 105, as in the first embodiment, is operatively connected to the steering mechanism of the vehicle 101 and governs the steering angle of the supporting wheels 110 of the vehicle in accordance with the selected position of the contacting element 112. The contacting element 112 is so designed to remain spaced above the bottom surface 109 of the guide channel 107 when traveling along the linear track.
As shown in FIG. 7, there is provided on the bottom of the guide channel 107 a run of rail 115 coextensive with the center line of the guide channel. There is also provided a branch rail 115' on the bottom of a branch guide channel 107'. The side of the rail 115 with which the element 112 is in contact will determine the path followed by the vehicle 101 at the branch or joining point of the tracks. The side selected by the contacting element 112 is controlled by means of, for example, electromagnetic means (not shown) which, in turn, is adapted to be controlled by a computer.
With reference to FIG. 8, at the junction of tracks there is provided a rail 115' extending from the branch track 109' to a track 119. To ensure the contact of the contacting element 112 with the rail 115', there is provided an outwardly bent portion 115" having an angle a with respect to the rail 115'. The manner of contact between element 112 and rail 115 or rail 115 is similar to that of the first embodiment and therefore need not again be described.
FIGS. 9 through 12 show a third embodiment of the present invention. A vehicle 201 is shown in FIG. 9 on a transportation module track 202. As in the first and second embodiments, the vehicle has a steering guide link 204 extending from the vehicle 201 through a slit 205 into a guide channel 207. Guide link 204 carries two horizontally placed guide wheels 206 and 206 on its lower crank portion. The two guide wheels 206 and 206 are in contact with the vertical inner walls 207' and 207" of the guide channel 207 so as to be guided thereby. In this embodiment, another guide wheel 208 is affixed to the lower end of the steering guide link, contacting the bottom surface 209 of the guide channel 207. The guide link 204 is connected to the steering mechanism of the vehicle 201 so as to steer the supporting wheels 210 of the vehicle 201, i.e., by governing the steering angle of the supporting wheels.
The most important features of the third embodiment, which differ from the previously described embodiments, are l) the guide follower means is eliminated, with the above two guide wheels themselves assuming that function and 2) the guide reference rail is also eliminated. The guide channels of the branch tracks of this embodiment have deeper or lower bottoms than the bottoms of the guide channels of the main tracks. v
At a track junction, the bottom 209 of the branch track guide channel 217 is dug, as shown in FIG. 9, to a level lower than that of the guide channel 207 of the main track 202. If the vehicle 201 is to be diverted from the main track 202 onto the branch track 202. the guide wheels 206, 206' and 208 of the steering guide link 204 are lowered into the deeper guide channel 217 in response to a computer signal, as shown in FIG. 12. To facilitate the return of the guide wheels 206, 206' and 208 to the level of the linear main guide channel 207, there is provided a slope 209" at the junction between the lower bottom 209 and the normal bottom 209, as shown in FIG. 9. The steering guide link 204 is held in position by means of a ratchet mechanism. When the steering guide link 204 is to be lowered at the junction of tracks, the steering guide link 204 is released from engagement with the ratchet mechanism in response to a computer signal.
The guide wheel 208 serves only to contact the bottom surface of the guide channel. When the vehicle travels along a main track, the ratchet mechanism remains in engagement with the steering guide link. When the vehicle approaches a main track from a branch track, the steering guide link will be raised by slope 209", thus bringing that linkage back into engagement with the ratchet mechanism.
The invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the claims rather than by the foregoing description, and all changes which come within the meaning and range of the equivalents of the claims are therefore intended to be embraced therein.
