FIELD: machine building.
SUBSTANCE: invention relates to automotive transmissions. Method of controlling position of gearbox actuator intended for engagement of gear ratio at end of preliminary phase of synchronization of two shafts of gearbox by means of traction machine, consists in the fact that monitoring of actuator switching to neutral position is performed during change of gear ratio by providing convergence of measured speed of one of two shafts with speed observed in form of function of inertia force value observed on this shaft, relative to expected value in form of gearbox actuator function and estimated value of machine torque.
EFFECT: method implies absence of position sensor.
