Consideration is given to the magnetorheological principle 
of control of an electrohydraulic brake device. The level of dissipation 
losses in the channel of the control unit, which determines the braking 
force in such systems, is regulated by a magnetic field adjusting 
a magnetosensitive pressure fluid to a prescribed effective viscosity. 
In an experiment, control of the main parameters characterizing the 
force and frequency characteristics of the device has been accomplished. 
It is found that the characteristic time of developing a braking force 
is 10-3 sec, and the speed of response 
of the system is mainly limited by the frequency characteristics of 
the inductor of the magnetic field of the magnetorheological throttling 
valve.
