摘要： A control apparatus for an engine is configured to control the engine provided with: an exhaust-driven supercharger, provided with an adjusting mechanism which can change supercharging efficiency according to an opening degree, in an exhaust passage, and having a first control mode and a second control mode as a control mode of the adjusting mechanism, the first control mode allowing the opening degree to be maintained at a maximum supercharging efficiency opening degree at which the exhaust-driven supercharger has maximum supercharging efficiency without using a deviation between a target supercharging pressure and an actual supercharging pressure, the second control mode allowing the deviation to be fed back to the opening degree; and an electrically-driven supercharger driven by electric power supplied from a power supply. The control apparatus is provided with: a determining device configured to determine whether or not an electrified amount of the electrically-driven supercharger decreases; and a maintaining device configured to maintain the control mode in the first control mode before it is determined that the electrified amount decreases.

摘要： The variable compression ratio internal combustion engine 1 comprises: a variable compression ratio mechanism 6 able to change a mechanical compression ratio; an exhaust promotion mechanism 50, 55 able to reduce cylinder residual gas after an exhaust stroke of cylinders; and a control device 80 configured to control the mechanical compression ratio by the variable compression ratio mechanism and control an operation of the exhaust promotion mechanism. The control device is configured to operate the exhaust promotion mechanism in at least a partial time period of a time period from when it is demanded that the mechanical compression ratio be raised to when the mechanical compression ratio finishes being changed.

摘要： A control device of an electric vehicle includes: a target rotation speed calculation unit that calculates a target rotation speed of a drive wheel based on a vehicle body speed; and a slip control unit that detects a slip of the drive wheel when a wheel speed exceeds the target rotation speed of the drive wheel and that controls motor torque of the motor in such a manner that the wheel speed becomes an appropriate rotation speed in detection of the slip. Further, the slip control unit controls the motor torque by feedback control according to a difference between the rotation speed of the motor and the target rotation speed of the drive wheel in detection of the slip.

摘要： The control apparatus closes the throttle, opens the bypass valve and supplies electric power to the electric compressor in a case where the remaining battery power of the battery is larger than the reference level when regenerative braking is performed with the first motor generator. The electric compressor is provided on the intake passage upstream of the throttle. The bypass valve is provided on the bypass passage that bypasses the electric compressor. According to the hybrid vehicle configured as above, regenerative braking force to be required can be obtained by performing electric power regeneration using the generator even when there is a constraint on regenerated electric power that the battery can accept.
