Abstract: A vehicular control system includes a smart key carried by a user and operated by an embedded battery and a verification ECU mounted in a vehicle. A wireless communication is made between the smart key and the verification ECU. The smart key performs periodically a switchover of a detection sensitivity for detecting a transmission electric wave transmitted from the verification ECU between a normal sensitivity and a high sensitivity. The high sensitivity has a detection area of the transmission electric wave greater than a detection area of the normal sensitivity. The constant use of the high sensitivity is unnecessary to detect the transmission electric wave. This enables a reduction of the consumed electric current of the battery for detecting the transmission electric wave with the high sensitivity.

Abstract: 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 ?m 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.
