Control apparatus and control method for hybrid vehicle

A control apparatus for a hybrid vehicle, the hybrid vehicle including an engine, a first motor, a second motor, a storage device, a first rotating element, a second rotating element, a third rotating element, an output member, a power split mechanism and a clutch, the first motor and the second motor respectively having an electricity generating function, the storage device supplying electric power for driving the first motor and the second motor and being charged with electric power generated by at least one of the first motor and the second motor, the first rotating element being coupled to the engine, the second rotating element being coupled to the first motor, the third rotating element being coupled to the output member and the second motor, the power split mechanism producing a differential action in the first rotating element, the second rotating element and the third rotating element, and the clutch being provided in a power transmission path leading from the engine to drive wheels, the clutch transmitting torque between the engine and the drive wheels when engaged, the clutch interrupting the transmission of torque between the engine and the drive wheels when released, the control apparatus comprising:

• an ECU for controlling, due to a malfunction, a regeneration control for the second motor in a released state of the clutch, the ECU configured to, when the clutch is kept in the released state and the clutch cannot be engaged and an amount of electrical charge of the storage device is higher than a prescribed first threshold value, and when the vehicle decelerates, execute the regeneration control for the second motor in order to consume electric power of the storage device by driving the first motor so that regenerative torque and motor torque produced by the second motor during the regeneration control is applied to the drive wheels as brake torque.
