POWER TRANSMISSION DEVICE FOR A VEHICLE AND THE METHOD OF CONTROL OF A POWER TRANSMISSION DEVICE Russian patent published in 2019 - IPC B60K17/02 F16H1/16 F16H15/00 F16D13/00 

FIELD: transportation.

SUBSTANCE: invention relates to the vehicles. Power transmission device in the vehicle contains a friction clutch, an electric motor, a worm gear transmission mechanism, a conversion mechanism and an electronic control module. Rapid zoom control is a control mode in which the angle of rotation of an electric motor increases to a first angle of rotation with a first speed gradient. First rotation angle exceeds the required rotation angle, which is required in order to maintain the friction clutch in the fully engaged state. Gradual reduction control is a control mode in which the angle of rotation of the electric motor, increased by controlling the rapid increase, is reduced to a second angle of rotation with a second gradient. Second angle of rotation is equal to or exceeds the required angle of rotation and is smaller than the first angle of rotation, with the second velocity gradient being less than the first velocity gradient.

EFFECT: decreases the average value of the motor current.
