HYBRID VEHICLE CHARACTERISTIC ONLINE ADAPTATION METHOD Russian patent published in 2020 - IPC B60W20/00 

FIELD: vehicles.

SUBSTANCE: invention relates to a method for on-line adaptation of at least one hybrid vehicle characteristic, having a hybrid transmission with electric drive, which is powered by current from electric energy accumulator, wherein at least one characteristic is used to select operating mode and/or to determine hybrid transmission working point, characterized by the following stages: (a) establishing multiple boundaries (2–7) of subdivision for subdivision of area (1) of charge state of energy accumulator into several areas, wherein at least one of subdivision boundaries (3–6) can be set in a variable manner during vehicle operation; (b) setting profile (10, 11) of at least one characteristic depending on state of energy accumulator charge, wherein values (13–16) of at least one characteristic are set by constants at division boundaries (2–7); and (c) online adaptation of at least one feature in case of shifting at least one of subdivision boundaries (3–6), wherein at least one characteristic, with allowance for permanently preset values (13–16) at boundaries (2–7) of subdivision and in accordance with shifted variable(s) boundary(s) of subdivision, is shifted and scaled.

EFFECT: disclosed is a hybrid vehicle characteristic online adaptation method.
