METHOD FOR BACKFLASH COMPENSATION IN GEARTRAIN BETWEEN THE STEERING WHEEL AND THE STEERING CONTROL VALVE Russian patent published in 2017 - IPC B62D5/09 

Abstract RU 2622323 C2

FIELD: automotive industry.

SUBSTANCE: group of inventions relates to a steering control system with a hydraulic booster and a method of operating the steering control system with the hydraulic booster of the motor vehicle, wherein the steering control cylinder that applies a supporting force to the geartrain of the steering control, is integrated into the hydraulic circuit via the steering control valve. Opening of the steering control valve provides a supporting force according to the rotation turning torque applied to the steering wheel through the geartrain with a backlash. The steering control system also comprises a drive which affects the geartrain in order to trigger its relative adjustment. The method of operation comprises a compensating step, where, provided the change in the rotation direction is detected, the geartrain is relatively adjusted through the drive in the direction opposite to the preceding geartrain engagement for a predetermined duration or a predetermined adjustment interval.

EFFECT: increased operation efficiency.
