Title: Improvements in and relating to apparatus for controlling the steering of vehicle wheels
Inventor: GUILBAUD JEAN-PIERRE
IPC: B62D7/02
Filed: 1969-03-28
Abstract: 1,217,285. Steering vehicles. COMMISSARIAT A L'ENERGIE ATOMIQUE. 28 March, 1969 [9 April, 1968], No. 16421/69. Heading B7H. An arrangement for controlling the steering of the wheels of a vehicle, the pivotal axes of said wheels intersecting a plane at the vertices of a polygon which can be inscribed within a circle 13 referred to as a base circle, characterized in that the axes of rotation of the wheels converge continuously toward the centre of rotation of the vehicle and the circle 13 which circumscribes the base polygon corresponds by means of a geometrical transformation to a reference circle 12, in a reference plane, said centre of rotation being related selectively to a point, for convenience called a transformed point, in said reference plane or to the conjugate of said point with respect to said reference circle. Fig. 3 illustrates a construction in which the translation of the centre of rotation is carried out in a direction parallel to the diameter AB of the reference circle. As shown the diameter GH of the reference circle coincides with the extended diameter AB, such that slot 11 is common to the points C, C<SP>1</SP> which relate the pivotal motion of the wheels according as to whether the centre of rotation is located inside or outside the base circle or in other words is directly related to its transformed point within the reference circle or to the conjugate of this point. The geometrical transformation which produces a transition from the base circle to the reference circle is a translation; other transformations, especially a similitude, could be used. Fig. 4 shows a mechanical method of performing the invention wherein slotted arms 45 and 46 can be selectively engaged with members 28 and 35, depending on whether the centre of rotation is to be inside or outside the base circle respectively. In another embodiment, Fig. 5 (not shown), the slot can be pivoted in its plane so that the centre of rotation can be moved to any position. An electrical method for performing the invention, Figs. 7-9 (not shown), comprises a control plate having a reference circle (114), which is deduced from the base circle by virtue of a similitude, on which is disposed a set of circular electric control potentiometers (115, 116) at the vertices of the reference polygon and having sliding contacts (123, 124) which are caused to  converge toward a common control pin (127), said pin being capable of displacement along a diameter of said reference circle and the pivotal  shafts (113) of the wheels being driven by individual steering motors supplied as a function of the relative positions of the contact resistors 124 and of sliding contacts (131, 132) of shaft potentiometers (117, 118) which are each associated with a corresponding potentiomter of said control plate.
