VEHICLE BRAKE SYSTEM ANTILOCKING DEVICE Russian patent published in 2005 - IPC

FIELD: transport engineering.

SUBSTANCE: invention can be used in automobile and other wheeled vehicles. Proposed antilocking device contains electronic unit with vehicle wiring system connected to terminals of electric connector of electronic unit, and also driven and driving wheels rotation pickups, electromagnetic valves of brake pressure modulator and pilot lamp and manometric stop light switch installed in operating brake system whose electric on contact is connected with winding of stop light cut-in relay. Electronic unit is made in form of single-chip microcomputer with volatile on-line memory for keeping parameters and braking effici9ency, whose input/output ports are connected to supply source, shapers of input signals of wheel rotation pickups, and, through corresponding matching amplifiers or logic keys with high or low level of output signal, to terminals of electric connector, functions of control of parameters and braking efficiency being program-implemented in single chip microcomputer. Electronic unit is furnished additionally with output and matching amplifier or logic key with low level of output signal whose input is connected to one of vacant input/output ports of single-chip microcomputer and output, through additional terminal of electric connector, is connected to winding of said stop light cut-in relay parallel to electric contact of manometric stop light switch.

EFFECT: enlarged functional capabilities of devices at simultaneous increased safety of vehicle.
