A hybrid vehicle includes a differential device, a first motor, an engine, a second motor, an engagement device, and an electronic control unit. The electronic control unit is configured to control the first motor and the second motor when an engagement state of the engagement device changes, such that a first angular acceleration and a second angular acceleration reach a first target value and the second target value respectively, the first angular acceleration and the second angular acceleration being two angular accelerations of the engine, the first motor, and the second motor and to calculate the first target value and the second target value by applying a constraint condition to at least one of the first target value and the second target value.

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.

A vehicle includes an internal combustion engine that generates power for rotating drive wheels, a differential mechanism that is provided between the engine and the drive wheels, and has at least three rotary elements including a first rotary element coupled to the engine, and a second rotary element coupled to the drive wheels, and a controller configured to control the engine. The controller is configured to determine whether to perform correction to increase the power generated by the engine, or perform correction to reduce the power, depending on a rotational speed of the second rotary element, when it changes a rotational speed of the engine.

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.
摘要:
A laser beam printer which forms a latent electrostatic image on a photoreceptor with a laser beam to perform an image recording operation, including scanning density switching means for selectively switching a scanning density of the laser beam on the photoreceptor within a plurality of values, and parameter switching means for selectively switching a parameter other than the scanning density of the laser beam within a plurality of values in the steps of producing a print. The parameter is, for example, a quantity of the laser beam, a width of the laser beam for one pixel in the main scan direction, or the like. A switching operation of the parameter switching means is controlled in accordance with a value of the scanning density selected by the scanning density switching means.

摘要:
An image forming apparatus having a built in AC voltage control circuit which enables the apparatus to be used in regions of the world having commercial power supplies with different supply voltages. The AC voltage control circuit first compares the input voltage to a reference voltage and then performs a switching operation to ensure that the voltage supplied to the AC electric components of the image forming apparatus is the voltage necessary for operation of those components.
