When a large truck makes a turn of large radius, the driver may make a steady steering input and the swept path of the vehicle through the turn may be computed by an offtracking procedure. However, when a large truck must make a turn of small radius, such as a right turn at an urban intersection, the driver must devise a more complex steering input that minimizes intrusion of the vehicle into the space of other vehicles and also keeps the trailer vehicle units from encroaching on the curb. Determination of the steering input necessary for such a turn is defined as a steering-path problem. In this paper is described a purely geometric approach to the solution of the steering-path problem that results in steering inputs and swept paths typical of those observed in real turning maneuvers by large trucks. The method has been implemented as a computer program for IBM mainframe computers.
