Stability of a wheeled vehicle against overturning characterizes its ability to maintain a given position during the movement on the slope. One of the most important performance indicators of a wheeled vehicle on a slope is its lateral stability, which characterizes its ability to work on slopes without tipping over. Ensuring reliable lateral stability of wheeled vehicles is the most important condition for their trouble-free operation. The paper deals with mathematical and simulation modeling of tricycle stability against tipping on a slope. The tricycle can lose stability. The most dangerous mode of movement of a wheeled vehicle is driving on a slope, which can cause loss of stability. It is noted that the influence of structural and operational factors creates a tipping moment, which worsens the stability of the tricycle against tipping on the slopes. Studies have shown that increasing the stability of the tricycle against overturning when moving along the slopes in a transverse direction, can be achieved by shifting the center of mass from the longitudinal axis of the tricycle towards the elevation of the slope, i.e., by tilting the frame of the relative rear bridge in a perpendicular plane relative to the direction of movement towards the elevation of the slope, such a change in parameters contributes to increasing the stability against overturning on the slope, since the restoring moment will increase relative to the overturning moment.
