METHOD AND DEVICE TO DETERMINE CONDITION OF GEAR BOX, AND VEHICLE COMPRISING SUCH DEVICE Russian patent published in 2013 - IPC F16H59/38 F16H59/68 F16H61/12 B60W10/02 B60W10/06 B60W10/10 

FIELD: motor industry.

SUBSTANCE: method includes stages, at which an engine torque is established, as well as angular acceleration of an input shaft of a gear box. The gear box condition is determined on the basis of the torque and angular acceleration. The ratio is established between the torque and the angular acceleration. It is determined, whether the ratio matches with the moment of inertia of the input shaft of the gear box. The device comprises a facility to determine vehicle engine torque, a facility to determine angular acceleration of the gear box input shaft, a facility to determine condition of the gear box, a facility for establishment of the ratio between torque and angular acceleration, a facility to determine, whether the ratio matches the moment of inertia of the gear box input shaft. The vehicle comprises the above device.

EFFECT: improved efficiency of a vehicle.
