  • Patent number: 9120482
    Abstract: A control device for a vehicle drive configured with a power transfer path that includes a first engagement device, a rotary electric machine, and a second engagement device. These elements being arranged in this order from an input member coupled to an engine to an output member that is coupled to the wheels of the vehicle. The control device is configured with an control section that controls output torque of the rotary electric machine such that a rotational speed becomes closer to a target rotational speed with both the first and second engagement devices brought into a slip engagement state and with the rotary electric machine generating electric power. The control section maintains control in which at least one of a temperature of the rotary electric machine and a temperature of an inverter is monitored as a monitoring target temperature.

  • Patent number: 9090248
    Abstract: A hybrid vehicle includes an electric steplessly speed changing unit, an engaging device, and an electronic control unit. The electric steplessly speed changing unit includes a differential mechanism including a first rotary element to which an engine is coupled, a second rotary element to which a first rotary machine is coupled, and a third rotary element as an output rotary member of the differential mechanism to which a second rotary machine is coupled. Differential operation of the electric steplessly speed changing unit is controlled by controlling operation of the first rotary machine. The engaging device is provided in a power transmission path between the third rotary element and drive wheels. In control of the hybrid vehicle, when at least one of the first rotary machine and the second rotary machine is operated with a predetermined positive or negative maximum torque, the electronic control unit controls a slip amount of the engaging device by changing the torque capacity of the engaging device.

  • Patent number: 8932178
    Abstract: A vehicle includes a transmission between an engine and a drive wheel and includes a differential mechanism (planetary gear mechanism) between the engine and an engagement device (transmission). A controller (ECU) included in the vehicle calculates a variation rate in the whole rotation energy of the planetary gear mechanism when it is in the inertia phase of a shift. The ECU increasingly corrects an engine generated power and decreasingly corrects a transmission transfer power when the variation rate is higher than 0. The ECU decreasingly corrects the engine generated power and increasingly correct the transmission transfer power when the variation rate is lower than 0.
