LONG-WHEELBASE TRACTOR-TRAILER TRAIN CONTROL SYSTEM Russian patent published in 2016 - IPC B62D13/00 B62D53/08 

FIELD: transport.

SUBSTANCE: invention relates to road vehicles controlling devices. Long-wheelbase tractor-trailer train control system comprises tractor-trailer train folding angle transducer and feedback sensor by semitrailer controlled axes position, electrically connected with electronic control unit (ECU), manual control unit via radio channel, connected to the ECU, tractor driving wheels turning angle transducer, lateral acceleration and angular velocity sensors relative to semitrailer vertical axis, semitrailer wheelbase measurement sensor, speed transducer and hydraulic accumulators with specified fluid pressure maintaining unit. ECU has main and correcting control channels. By inputs ECU is connected with master sensor and feedback sensors, and by outputs is to control system actuator. Control system is made in form of electrohydraulic booster, consisting of four-port three position electrically-operated flow control device. Flow control device is connected with double action actuating power cylinders. Power cylinders are mechanically connected with semitrailer controlled axes and its frame and hydraulically connected with hydraulic pump and hydraulic tank via four-port three position electrically-operated flow control device.

EFFECT: enabling higher maneuverability and controllability of long-wheelbase tractor-trailer train.
