Abstract: An engine starting system for starting an engine promptly during propulsion without reducing a drive force. When a condition to crank the engine is satisfied during propulsion in a neutral stage, torque is applied to an input rotary element to crank the engine by reducing a rotational speed of a control rotary element by increasing a torque capacity of a first engagement device to utilize an inertial force of the free rotary element as a reaction force.

Abstract: A drive force control system configured to reduce a total energy consumption of a hybrid vehicle. The drive force control system calculates: an output power of the engine which can optimize a thermal efficiency given that the engine is operated at a best fuel point; and a required electric power to be supplied from a battery or to be generated by a control motor, which can adjust the drive power established by the output power of the engine to the required power. A power exchange between the control motor and the battery is interrupted if the required electric power to be supplied from the electric storage device or to be generated by the control motor is less than a first predetermined electric power.

Abstract: A hybrid vehicle includes: an engine; first and second rotating electric machines; a connection/disconnection mechanism; a power storage device; and a control device. Further, when an acceleration request occurs during EV traveling mode, the control device controls, when determining that a predetermined acceleration smaller than a requested acceleration and corresponding to a vehicle speed cannot be generated by torque output by the second rotating electric machine, the torque output by the second rotating electric machine so as to generate an acceleration less than the predetermined acceleration while controlling the torque by the engine and torque by the first rotating electric machine, and when determining that the predetermined acceleration cannot be generated by the torque output by the second rotating electric machine, controls the torque output by the second rotating electric machine so as to generate the acceleration equal to or greater than the predetermined acceleration.

Abstract: To improve accuracy in misfire determination, a control apparatus for an internal combustion engine that controls an internal combustion engine having a variable compression ratio mechanism capable of changing the compression ratio of the internal combustion engine includes a controller configured to: determine that a misfire occurs if the magnitude of rotational fluctuation of the internal combustion engine is equal to or larger than a misfire criterion value and to make the misfire criterion value larger during the time in which changing of the compression ratio of the internal combustion engine is in progress than during the time in which the compression ratio is not being changed.
