Annotation: The problem on manoeuvrability improving of the two-link lorry convoy consisting of biaxial truck tractor and uniaxial semi-trailer has been solved. The proper choice of linear law of management provides sufficient construability of the two-link road train at motion in a circular corridor. The area of the rectilinear motion stability has been determined in the sphere of the guided parameters (transmission coefficient and longitudinal velocity) : a negative transmission coefficient results the intensive skidding of semitrailer the (case of stability loss of rectilinear motion), as the supporting axis of semitrailer is oriented toward the decliration of semitrailer, itself and the center of the tractor mass tries to move on a convoluting spiral; the positive transmission coefficient results the «moderate» deviation of trajectory of the truck mass centre from the primary rectilinear direction of motion (stabilizes the rectilineal configuration of the two-link lorry convoy). Numerical constructions are given sets of the one-parameter set of steady regime on the basis of the differential-geometric method of parameter continuation.
Keywords: mathematical model of lorry convoy, swaying instability, transmission coefficient, method of continuation on a parameter, stability of motion.
