Abstract
This paper considers the solution to the current problem of studying the restrictions related to auto mode, which is imposed on the pressure in the brake cylinder helping to substantiate its rational characteristics of pressure from car loading. This paper studies in detail the condition for preventing skidding, which provides determination of the maximum permissible pressure in the brake cylinder. The dependence of the pressure in the brake cylinder was obtained from the condition of skidless braking. A function is also derived that is a limitation of the maximum pressures in choosing auto mode parameters such as a function of the permissible maximum pressures in the brake cylinder from the axial load of the car for a speed that determines the minimum value of the adhesion coefficient.
