The paper considers the solution to the problem of minimizing the longitudinal-angular oscillations of a mining dump truck that occurs when driving on rough roads. An algorithm has been developed for damping longitudinal-angular oscillations by briefly changing the traction and braking torques on the driving wheels, depending on the phase of oscillations of the sprung mass of the truck. The algorithm was approved using a dynamic mathematical model of a mining dump truck. The results of the comparative analysis showed the possibility of reducing the duration of the oscillations by 54 % and the amplitude of the oscillation by 40 % when moving an individual asperity, and when the truck moves along the road with characteristics corresponding to the road surface in the mining dump, the root-mean square accelerations at the driver’s workplace can be reduced by 19.5 %.
