This paper presents a study outcome whereby the method of analyzing the stability with regard to the skid of wheeled vehicles with the consideration of variable velocity value along the curvilinear sections of the way and longitudinal angular oscillations of the sprung part has been developed. The longitudinal - angular oscillations of the sprung part reduce the critical speed value of steady motion; accelerated movement of the vehicle along the curvilinear section of the way for larger values of acceleration of the front axle skid occurs at lower velocity values (rear for the larger ones), for slow motion on the contrary. As for the impact of the power characteristics of the sprung system, then for the same values of all other parameters (amplitudes of longitudinal - angular oscillations, static deformations, acceleration (deceleration)), the progressive characteristic of the sprinkler system corresponds to the greater value of the critical speed of the stable motion as a regressive one. The theoretical contribution of the reported study in that the obtained results can serve as a base for study the influence of the kinematic parameters of the vehicle's motion on its controllability.
