Toyota was the largest automobile manufacturer in 2012 ahead of the Volkswagen Group and General Motors. In July of that year, the company reported the production of its 200-millionth vehicle. Toyota is the world's first automobile manufacturer to produce more than 10 million vehicles per year. It did so in 2012 according to OICA, and in 2013 according to company data. As of July 2014, Toyota was the largest listed company in Japan by market capitalization and by revenue.The company was founded by Kiichiro Toyoda in 1937 as a spinoff from his father's company Toyota Industries to create automobiles. Three years earlier, in 1934, while still a department of Toyota Industries, it created its first product, the Type A engine, and, in 1936, its first passenger car, the Toyota AA. Toyota Motor Corporation produces vehicles under 5 brands, including the Toyota brand, Hino, Lexus, Ranz, and Scion. It also holds a 51.2% stake in Daihatsu, a 16.66% stake in Fuji Heavy Industries, a 5.9% stake in Isuzu, and a 0.27% stake in Tesla, as well as joint-ventures with two in China , one in India , one in the Czech Republic , along with several "nonautomotive" companies.

Arranged downstream of a particulate matter filter incorporated in an exhaust pipe is a PM sensor with a detection portion on which particulate matter is deposited to output a deposition amount of the particulate matter. An assumption condition is set for making an assumption that the particulate matter filter is in a reference condition having a predetermined particulate matter capturing capability. Under the assumption condition, a virtual output value is calculated depending on a virtual deposition amount of the particulate matter in the PM sensor. The particulate matter filter is determined to have fault when, upon reaching of the virtual output value to a predetermined determination threshold, an output of the PM sensor is not less than the determination threshold.

A selectable one-way clutch includes an engagement mechanism. The engagement mechanism is configured to be switched between an engaged state and a disengaged state. The engaged state is a state in which relative rotation between a first and a second members in one of a positive rotational direction and a reverse rotational direction is restricted. The disengaged state is a state in which the relative rotation between the first member and the second member in both of the positive and the reverse rotational direction is permitted. The electronic control unit is configured to apply torque to the one of the first member or the second member by using a motor such that relative rotation in the other one of the positive or the reverse rotational direction is generated between the first member and the second member when the engagement mechanism is switched from the engaged state to the disengaged state.


A core has first to third magnetic leg portions (151-153). First and second windings (121a, 121b) wound on the first and second magnetic leg portions (151, 152), respectively, are connected in series to constitute a first reactor. A third winding (122) wound on the third magnetic leg portion (153) constitutes a second reactor. A magnetic field (211, 212) produced from the first reactor and a magnetic field (213) produced from the second reactor reinforce each other in the second magnetic leg portion (152), but weaken each other in the first magnetic leg portion (151). In accordance with increase in currents, the operation of the first and second reactors changes from a magnetically uncoupled mode in which the first and second reactors operate in a magnetically non-interfering state to a magnetically coupled mode in which the first and second reactors operate in a magnetically interfering state.

An internal combustion engine comprises an upstream side exhaust purification catalyst (20) and a downstream side exhaust purification catalyst (24). The control device comprises a storage amount estimating means which estimates the oxygen storage amount (OSAulc) of the downstream side exhaust purification catalyst, and can execute fuel cut control which cuts the feed of fuel to the combustion chamber during operation of the internal combustion engine when the engine speed NE is the lowest reference speed NElow or more. The control device lowers the lowest reference speed when the storage amount estimated by the storage amount estimating means has become a given limit storage amount Clim or less, compared with when it is larger than the limit storage amount. As a result, a control device can effectively keep the oxygen storage amount of the downstream side exhaust purification catalyst from decreasing to zero.


An up-drawing continuous casting method includes drawing up molten metal (Ml) held in a holding furnace (101), through a shape determining member (102) that determines a sectional shape of a cast casting (M3). The sectional shape determined by the shape determining member (102) includes a round-cornered portion, and a value (Rf) of a curvature radius of the round-cornered portion that is determined by the shape determining member (102) is smaller than a design value (Rt) of a curvature radius of a round-cornered portion of the casting (M3).

A camera captures an image of objects outside a vehicle through a window of the vehicle. An image processing unit determines whether a captured image captured by the camera is clear or blurred. A control unit activates a temperature raising unit to raise temperature of a window area which is an area of the window which is included in an imaging range of the camera if the image processing unit determines that the captured image is blurred so as to be in a blurred state. If a blurred state of the captured image is not dissolved by the time when a predetermined period of time elapses since the temperature raising unit is activated, the control unit suspends activation of the temperature raising unit when the predetermined period of time elapses and prohibits subsequent activation of the temperature raising unit.
