    Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of such a state that friction braking torque cannot temporarily follow a change, concerning regenerative braking torque during cooperative braking for cooperatively controlling a friction brake device and a regenerative brake device. SOLUTION: Regenerative electric power generated by operating a second motor 16 as a generator is charged in a battery 48. In addition to the second motor 16, an electrical apparatus 58 which receives and delivers electric power from/to the battery 48 is placed on a vehicle. When a load by the electrical apparatus 58 changes, regenerative braking torque may change because I/O electric power of the battery is limited. The change in regenerative braking torque is suppressed by limiting the speed of a load variation of the electrical apparatus 58 to not more than a predetermined value, thus allowing friction braking torque to follow.

    Abstract: PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine capable of keeping deterioration of fuel economy at the minimum while inhibiting generation of abnormal noise and the like. SOLUTION: The control device for the internal combustion engine is suitably used for controlling the internal combustion engine based on an operation line. To put it concretely, an operation line setting means sets the operation line so as to reduce abnormal noise of the internal combustion engine based on torque fluctuation (combustion fluctuation in another word) of the internal combustion engine. Consequently, deterioration of fuel economy can be kept at the minimum while inhibiting generation of abnormal noise of the internal combustion engine such as booming noise.

    Abstract: PROBLEM TO BE SOLVED: To suppress the performance deterioration of a battery by properly controlling the engagement/release of an engagement mechanism configured to fix the revolution of a first motor generator.
    SOLUTION: The control device of a hybrid car is suitably applied to a hybrid car equipped with an engine, a motor generator, and an engagement mechanism configured so as to be engaged to fix the revolution of a first motor generator. Concretely, the control means controls the switching of the engagement/release of the engagement mechanism based on the status (SOC or temperature) of a battery in which a power is transferred between the first and second motor generators. Thus, it is possible to properly observe the input/output restriction of the battery, and to suppress the deterioration of the performance of the battery.

    Abstract: PROBLEM TO BE SOLVED: To suppress generation of noise when fastening a driving system caused by reversal of torque by preventing the reversal of the torque outputted to an input shaft of a transmission from an electric motor when an internal combustion engine is in an operation state generating vibration or booming noise. SOLUTION: When target engine speed Ne* and target torque Te* of an engine are present in booming noise area and when temporary torque Tm2tmp is within a prescribed area range including a value 0 by a threshold value Tref, a shift stage of the transmission is upshifted (S210), and torque instructions Tm1*, Tm2* of the motors MG1, MG2 are set such that request torque Td* is outputted to a driving shaft out of the prescribed area range of the temporary torque Tm2tmp though it is present in the booming noise area. Thereby, when the engine is operated in the booming noise area, the generation of the noise due to fastening which may be generated by reversing the torque of the motor MG2 can be suppressed.
