Patent attributes
A controller for a hybrid electric vehicle includes an engine ECU and a HEVECU. The engine ECU executes a partial cylinder fuel cut-off control that stops supply of fuel to one or more cylinders and supplies fuel to the remaining ones of the cylinders. Further, the engine ECU sends control information of the partial cylinder fuel cut-off control to the HEVECU. The HEVECU executes a driving force compensation control so as to compensate for, using driving force of a motor generator, a decrease in driving force of a multi-cylinder engine that results from the execution of the partial cylinder fuel cut-off control. The engine ECU prohibits the execution of the partial cylinder fuel cut-off control when an anomaly possibly occurs in the sending and receiving of the control information of the partial cylinder fuel cut-off control.
