FIELD: transportation.
SUBSTANCE: in the method to control an n-axial trailer of a tractor they determine speed of trailer wheels rotation, send it to a control unit, where signals from the tractor braking system are also sent. A braking force is calculated for each of trailer's wheels, which is sent to a braking drive of the trailer. Control action is formed and sent to corresponding trailer brakes. During braking, mechanical energy is accumulated at m axes of the n-axial trailer, where m≤n. In process of motion, the accumulated mechanical energy is sent to m axes. Braking is carried out with account of the current value of the accumulated mechanical energy level. The device for method realization comprises a control unit, a tractor brake pedal sensor and sensors of trailer and tractor wheel rotation speed, braking mechanisms of the trailer, mechanical energy recuperators fixed on m axes of the trailer, an indicator and a regulator of recuperators charging and a controller.
EFFECT: vehicle dynamics improves.
