  • Patent number: 9821795
    Abstract: A hybrid vehicle includes an engine, a rotary electric machine, a filter and an ECU. The engine includes an exhaust passage. The rotary electric machine is a driving source of the vehicle. The filter traps particulate matter flowing through the exhaust passage. The ECU is configured to control the hybrid vehicle in any one of a plurality of control modes. The plurality of control modes include a first control mode and a second control mode. The number of opportunities for the engine to operate when the control mode is the second control mode is larger than the number of opportunities for the engine to operate when the control mode is the first control mode. The ECU is configured to, when the filter is regenerated, control the hybrid vehicle in the second control mode.

    Abstract: An image forming apparatus includes a first pressing member configured to press a unit that has a second rotating member that can come into contact with a first rotating member, and a supporting member rotatably supporting the second rotating member. The first pressing member moves the supporting member so that the second rotating member moves from the contact position to the separated position. Also provided is a second pressing member that presses the supporting member. The second pressing member is capable of moving between a mounting/detaching restriction position where mounting/detaching of the cartridge to/from the apparatus main body is restricted, and a mounting/detaching allowing position where mounting/detaching of the cartridge to/from the apparatus main body is allowed.

  • Patent number: 9180871
    Abstract: A hybrid vehicle including an engine having a catalyst in an exhaust passage, first and second motor generators, a battery and a power transmission mechanism coupling a drive shaft, the engine and the motor generators by a gear mechanism such that torque is transmittable, and its control method, are provided. When a coolant temperature is a threshold or below, catalyst warm-up operation for starting the engine and retarding an ignition timing by a retardation amount is executed. When a battery level is a threshold or below, forced charging operation for starting the engine and charging the battery by driving the first motor generator is executed. During the forced charging operation, an engine load is changed on the basis of the battery level. When the catalyst warm-up operation is executed during the forced charging operation, the retardation amount for facilitating warm-up of the catalyst is reduced as the engine load increases.

  • Patent number: 8635993
    Abstract: The invention relates to an air-fuel ratio control device of an internal combustion engine, comprising a plurality of means for independently introducing into each combustion chamber an exhaust gas discharged from combustion chambers to an exhaust passage. When at least one exhaust gas introduction means is under an exhaust gas introduction shortage state, a target value of an air-fuel ratio of a mixture gas is changed depending on whether an exhaust gas introduction control for introducing the exhaust gas into the combustion chamber by the exhaust gas introduction means is performed.

  • Patent number: 8511278
    Abstract: An idling-time target phase setting unit (130) variably sets a target phase based on a target idle speed that is set by a target idle speed setting unit. (110) Especially, when the target idle speed is lower than a predetermined rotational speed and operating noise of a variable valve timing mechanism (2000) is easily heard by, for example, a driver, the.idling-time? target phase setting unit (130) sets the target phase so that a range, in which the valve phase is allowed to change, is restricted within a phase region where a speed reduction ratio is high and the operating noise is relatively low.
