Abstract: When there is a demand for a heating operation of a vehicle and when there is a remaining charging capacity in a main battery, an upper limit value of a charging state of the battery is changed to a level-up upper-limit value, which higher than an ordinary upper-limit value. And an operating mode of an engine is changed to an efficiency prioritizing mode. When there is no remaining charging capacity in the main battery, the upper limit value of the charging state is changed to the ordinary upper-limit value. And the operating mode of the engine is changed to a waste-heat prioritizing mode, an engine efficiency of which is lower than that of the efficiency prioritizing mode. According to such a control, it becomes possible to warm up the engine and the battery, even in the case that there is no remaining charging capacity because of high charging state in the battery.

Abstract: A cooling system circulates a coolant between an engine, an inverter and a radiator to cool the engine and the inverter. A driving mode of the vehicle can be changed between an EV-mode in which the vehicle is driven only by the motor and an HV-mode in which the vehicle is driven by at least one of the motor and the engine. When a driving mode is EV-mode, a coolant temperature is increased to cool the inverter. In the EV-mode, a vehicle is driven by motor only. When the inverter temperature is increased, the allowable current of the inverter can be increased and an allowable output of a motor can be increased.

Abstract: Since a power of an engine is transmitted to a first axle and a power of a MG is transmitted to a second axle, a space for providing the MG can be readily ensured. Further, since an accessory is driven by the power of the engine, a private power source for the accessory is not necessary. In this case, the accessory may be a water pump, an oil pump, or an air-conditioner compressor. Furthermore, since a vehicle driving mode is switched between an engine driving mode and a MG driving mode, only a control system relative to the MG driving mode is necessary to be developed when the hybrid vehicle is developed by using the engine vehicle as the base part.

Abstract: A vehicle control apparatus computes a fuel consumption decrease or a fuel consumption increase for each of a plurality of travel modes. The vehicle control apparatus includes a control section that calculates an engine efficiency of an engine and an MG-INV efficiency which is a combined efficiency of a motor generator and an inverter. The engine efficiency is calculated based on an engine power and an ideal fuel consumption line. The MG-INV efficiency is calculated based on an MG power. As such, based on the engine efficiency and the MG-INV efficiency, the control section computes the per-unit-electric-power fuel consumption decrease or the per-unit-electric-power fuel consumption increase.

Abstract translation: 由于发动机的动力被传递到第一轴并且MG的动力被传递到第二轴，所以可以容易地确保用于提供MG的空间。 此外，由于附件由发动机的动力驱动，所以不需要用于附件的专用电源。 在这种情况下，附件可以是水泵，油泵或空调压缩机。 此外，由于在发动机驱动模式和MG驱动模式之间切换车辆驾驶模式，所以当通过使用发动机车辆作为基础部分开发混合动力车辆时，仅需要开发相对于MG驾驶模式的控制系统 。

Abstract: A first shaft has one end coupled to an engine. A damper has a spring coupled the other end of the first shaft. A second shaft has one end coupled to the spring. A third shaft rotates in correspondence to a final output shaft. A fourth shaft has one end coupled to a first rotary electric machine. A power split mechanism is provided among the second shaft, the third shaft and the fourth shaft and transfers torque among the second shaft, the third shaft and the fourth shaft. A control unit calculates a torque correction value for the rotary electric machine based on information indicating torsion angle of the damper and corrects the torque of the rotary electric machine based on a calculated torque correction value.
