Abstract The article provides a rationale for the need to develop an additional braking control system for a transport vehicle to limit the movement speed under the action of rolling forces and to protect the engine from exceeding the permissible speed, “overshooting” the speed. Design options for four systems that dissipate kinetic energy are considered, and the effectiveness of their use is assessed: in periodically switched off clutches in the transmission; in a hydraulic retarder, containing a rotor and a stator, where kinetic energy turns into heat and is dissipated into the environment; in two complex hydrodynamic transmissions, the design of which integrates a torque converter and a hydraulic retarder. In the first version of the system, kinetic energy turns into heat when the transmission clutches are periodically turned on and off; in the second option, energy transformation is carried out in the retarder circulation circle containing the rotor and the stator; in the third embodiment, in an additional circuit of the circulation circle of the working fluid of a hydrodynamic transmission, containing a pump, turbine, reactor wheels and an additionally introduced fourth wheel, which can serve as the stator; in the fourth version, the pump wheel of the torque converter can perform the additional function of the hydraulic retarder rotor, and the hydrodynamic transmission housing can function as the stator.
