    • A demand driving force parameter indicative of a demand driving force of the engine is set based on the accelerator pedal operation amount, and a target value of an engine driving force control amount is set based on the demand driving force parameter. The engine driving force control amount is controlled so as to coincide with the target value. A target rotational speed of the engine is set based on the demand driving force parameter, and the continuously variable transmission is controlled so that the rotational speed of the engine coincides with the target rotational speed. One of a first operation mode and a second operation mode is selectable, wherein the fuel consumption rate in the second operation mode is less than the fuel consumption rate in the first operation mode. When the second operation mode is selected, the demand driving force parameter corresponding to the accelerator pedal operation amount is set to a value which is smaller than a value of the demand driving force parameter in the first operation mode, and the target value is calculated based on a first predetermined characteristic preliminarily set according to the engine rotational speed and the demand driving force parameter. The first predetermined characteristic is set so that the target value corresponding to the same engine rotational speed is substantially constant in a first predetermined range of the demand driving force parameter.

    • An aluminum alloy material is welded by performing friction stir welding to form a welded section in an aluminum alloy welded component. The aluminum alloy material contains Mg: 0.3-6.0% (mass %, hereinafter the same), Cu: 0.2% or less, Si: 0.1% or less, Fe: 0.1% or less, the balance being Al and inevitable impurities. Second phase particles dispersed in the aluminum alloy material have a grain size of 5 μm or less as observed with an optical microscopic. Because the second phase particles are homogeneously dispersed in a welded section equivalent portion of the aluminum alloy welded component as compared to other portions, variations in pit formation caused by etching during anodizing are reduced, thereby eliminating color tone variations in the anodized coating formed on the aluminum alloy welded component.
    • 通过进行摩擦搅拌焊接来焊接铝合金材料,以在铝合金焊接部件中形成焊接部分。 铝合金材料含有Mg:0.3〜6.0%(质量%,以下相同),Cu:0.2%以下,Si:0.1%以下,Fe:0.1%以下,余量为Al和不可避免的杂质。 分散在铝合金材料中的第二相粒子的光学显微镜观察到的粒径为5μm以下。 由于与其他部分相比,第二相粒子均匀地分散在铝合金焊接部件的等效焊接部分的焊接部分中,所以在阳极氧化期间由蚀刻引起的凹坑形成的变化减小,从而消除了形成在阳极氧化涂层上的阳极氧化涂层的色调变化 铝合金焊接部件。
