AUTOMOBILE ANTILOCK BRAKE SYSTEM Russian patent published in 2006 - IPC B60T8/70 

FIELD: mechanical engineering; antilock brake systems.

SUBSTANCE: proposed antilock brake system consists of vehicle approximate speed calculating unit and braking systems of each wheel, each containing series-connected wheel angular velocity pickup and wheel speed calculating unit, and also first logic unit and unit to form signals to modulator. Said antilock brake system includes also braking hydrostatic control circuit, hydrodynamic circuit with adjustable delivery of brake fluid from hydraulic pump in proportion to pressure on brake pedal. Hydraulic drive of brake can operate in combination with hydraulic drive of steering booster, with throttling of delivery of fluid into brake circuit in proportion of 1:9 in favor of steering booster.

EFFECT: improved reliability of antilock system by increasing stability of operation of electric circuit.
