DEVICE FOR CONTROL OVER VEHICLE DRIVE Russian patent published in 2014 - IPC B60L11/14 B60W10/02 B60W10/08 B60W10/18 B60W20/00 B60K6/383 

FIELD: transport.

SUBSTANCE: set of inventions relates to drive device and method of vehicle control. In compliance with first and second versions, this control device comprises drive, motor, one-way gearbox, two-way gearbox, carrier speed or second axle rpm transducer, motor preset rpm transducer, motor rpm transducer and control unit. Drive is designed to transfer torque to first axle. Motor is designed to transfer torque to second axle. Control unit controls motor rpm and two-way gearbox actuation. In compliance with first version, control unit actuates two-way gearbox when motor operates as a power drive while motor rpm reaches threshold rpm lower than preset rpm. In compliance with second version, control unit controls the motor so that it generates preset torque at recuperation while motor rpm reaches threshold value lower than preset rpm.

EFFECT: decreased kicks in gearbox.
