Patent attributes
Disclosed is a control apparatus for a hybrid vehicle having an engine, a drive motor (3) that regenerates power, and an electric power storage device (6) that gives/receives power to/from the drive motor (3). The control apparatus includes power consumption means (2) for consuming power; a sensor (26, 27) that detects a state of charge of the electric power storage device; means (18, 23, 51) for detecting a driving state of the vehicle; and a controller (9). The controller (9) is programmed to calculate a chargeable energy amount Ecap in the electric power storage device (6) on the basis of a difference between a fully charged state of the electric power storage device and the detected state of charge; set a power |Pgen0| regenerated by the drive motor (3); calculate a chargeable power Pmax in the electric power storage device according to the detected state of charge; calculate a regenerated energy E resulting from regenerative braking from the detected driving state of the vehicle; calculate a charging power limit Pgenlmt according to the calculated regenerated energy E; and control the power consumption means (2) to consume a power equal to a difference between the power |Pgen0| regenerated by the drive motor (3) and the charging power limit |Pgenlmt| when the calculated regenerated energy E is greater than the chargeable energy amount Ecap in the electric power storage device and when the charging power limit |Pgenlmt| is smaller than the chargeable power |Pmax|.
