  • Patent number: 9638096
    Abstract: A vehicle is equipped with an internal combustion engine having a forced-induction apparatus with variable boost pressure, a first motor generator for generating electricity while applying negative torque to the engine, and a battery for storing the electricity generated by the first motor generator. During the operation of the engine, a target boost pressure is set lower as the rotational speed of the first motor generator is increased. The engine is controlled such that, with the boost pressure adjusted to the target boost pressure, the output torque of the engine has a required value determined by the accelerator operation amount. Further, while the output torque of the engine is adjusted to the required value, the magnitude of the negative torque by the first motor generator acting on the engine is adjusted such that the engine rotational speed has a target value.

  • Publication number: 20150166053
    Abstract: A clutch is configured to cut off or couple a power transmission path between an engine and a drive system. An engine starter is configured to start the engine. An electric motor is configured to be connected to an output shaft of the engine by coupling the clutch. An electronic control unit is configured to set an engine rotation speed at the time of coupling the clutch after starting the engine when a reverse torque or an external load is large in starting the engine in a state where the clutch is decoupled to be higher than the engine rotation speed when the reverse torque or the external load is small.

  • Patent number: 8674637
    Abstract: A vehicle includes a power storage device, a motor generator, a converter for stepping up an output voltage from the power storage device, an inverter for driving the motor generator, and an ECU. The inverter includes switching elements. The switching elements have a characteristic that the withstand voltage of the switching elements decreases as the temperature of the inverter decreases. The ECU sets the stepped-up voltage, based on a temperature characteristic of the power storage device and a temperature characteristic of the inverter, so that the stepped-up voltage is increased within a range in which the stepped-up voltage does not exceed the withstand voltage. In this way, at low temperatures, deterioration of the power performance can be suppressed while the switching elements are protected.
