the control system capabilities

  • Automatic and manual transmission control;
  • Smooth shifting of gears by controlling the pressure in the clutches with proportional electro-hydraulic valves;
  • Smooth shifting of gears by controlling the pressure in the clutches with proportional electro-hydraulic valves;
  • Protection against cyclic gear changes when driving in difficult road conditions;
  • Automatic control of hydrodynamic transformer blocking;
  • Automatic and command control of the retarder hydraulic valve;
    moving the car forward and backward only after pressing the service brake (safety);
  • Protection of the HMT from overloads when reverse is switched on while the vehicle is moving forward;
  • Reducing the load on the HMT clutches during gear changes due to engine control algorithms;
  • Protection of the engine and HMT from dynamic loads in case of incorrect gear shifting by the operator;
  • Parking brake system protection when starting the machine;
  • Diagnostics of the HMT, engine and the control system elements;
  • Slip control of transmission clutches.
