DRIVE CONTROL SYSTEM FOR HYBRID VEHICLE Russian patent published in 2017 - IPC B60K6/445 B60L11/14 B60W10/08 B60W20/00 F16H3/54 F16H3/72 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to hybrid vehicles. Drive control system for a hybrid vehicle with an engine, the power distribution unit, motors and braking device comprises a controller that sets the first operational mode where the vehicle is driven by a first motor and second motor. In the second operating mode the vehicle is powered by an engine or the second motor subject to the allowance of carrier rotation. The time is calculated after completion of the first operation mode. Energy distributor temperature is estimated according to the noted time duration. The first operating mode, when the estimated temperature is less or equal to a predetermined allowable temperature and the first operation mode is prohibited, when the estimated temperature is higher than the allowable temperature is provided.

EFFECT: drive control system, which reduces gearbox wear.
