METHOD FOR GEAR SHIFTING IN HYBRID VEHICLE Russian patent published in 2016 - IPC B60K6/365 B60W10/06 B60W10/08 B60W10/11 B60W30/19 B60W20/00 F16H61/04 

FIELD: machine building.

SUBSTANCE: invention relates to gear shifting in vehicle. In the method for gear shifting in gearbox during vehicle motion electrical machine and engine is controlled so, that they can exert zero torque to the gearbox shaft. Gear switched on in the gearbox is switched off when zero torque is obtained. Electric machine and engine are controlled so that each places the torque to the gearbox shaft, bringing the shaft to the rotation speed, which is synchronized for the existing vehicle speed with shaft rotation speed for gear to be switched on. When synchronized rotation speed is obtained, gear is shifted, electric machine and engine are simultaneously controlled and converted into a state for combined production of zero torque at the moment of gear shifting completion. Electric machine and engine are controlled for application of torque required by each of them, to the gearbox shaft.

EFFECT: improved vehicle driving.
