MOTION CONTROL SYSTEM FOR HIGH-SPEED TRANSPORT MACHINE Russian patent published in 2014 - IPC B62D11/00 B60W30/02 F15B21/02 

FIELD: transport.

SUBSTANCE: high-speed tracklaying vehicle (HSTLV) is equipped with hydromechanical driveline and differential steering device with hydrostatic drive. Automated motion control system consists of control actions (steering angle, fuel-feed pedals displacement) meters, as well as angle shaft angular velocity and travelling speed meters which are electrically connected via analogue-to-digital converter with on-board microcomputer generating specified steering angular velocity, gyro transmitter, two-channel spectrum analyser, electrohydraulic booster which moves hydrostatic drive control element via differential lever. Additionally, following elements are introduced in the system: identifier of control input type, two Shaper filters electrically connected with hydraulic drive by means of pressure sensors via spectrum analyser, oscillations suppression and operation speed regulators the signal from which is entering hydraulic drive via additive register and control signal shaper.

EFFECT: higher speed properties, dynamics and driveability of machine.
