MOTION MODE SELECTION CONTROLLER FOR HYBRID ELECTRIC VEHICLE Russian patent published in 2015 - IPC B60W20/00 B60K6/442 

FIELD: transport.

SUBSTANCE: invention relates to hybrid vehicle control. Hybrid electric vehicle motion mode switch controller contains vehicle motion speed determination module; driving accumulator charge state determination module and module to control switching between the first, the second and the third mode of motion based on vehicle speed and driving accumulator charge state. Switching control module performs switching between the second and the third mode at the first speed when state-of-charge is less than the first state-of-charge, and switching between the first and the third mode at a speed when state-of-charge is the first state-of-charge or more. The switching control module additionally contains module for required vehicle output power detection which performs switching between the second and the third mode at the second speed when state-of charge is higher than the first state-of-charge, and switching between the first and the third mode at the third speed in case when required output power is less than required output power.

EFFECT: reduced fuel consumption.
