    • 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.
    • 车辆控制系统包括由用户携带并由嵌入式电池操作的智能钥匙和安装在车辆中的验证ECU。 在智能钥匙和验证ECU之间进行无线通信。 智能钥匙周期性地执行用于检测从正常灵敏度和高灵敏度之间的从验证ECU发送的传输电波的检测灵敏度的切换。 高灵敏度具有大于正常灵敏度的检测区域的发送电波的检测区域。 不必使用高灵敏度来检测发射电波。 这使得能够以高灵敏度降低用于检测发送电波的电池的消耗电流。

    • A control system has regular ECUs and a recovery ECU. Each regular ECU controls driving of current consumers, respectively, drivable by driving methods and connected through output channels. The recovery ECU has output drivers, respectively, producing driving currents based on the driving methods and channel changing blocks corresponding to the respective driving methods. When receiving information indicating failure of an output channel of one regular ECU, the recovery ECU specifies the driving method of the failed channel, controls the driver of the specified driving method to produce a driving current, and controls the changing block of the specified driving method to select one output channel, through which the current consumer connected with the failed ECU through the failed channel is also connected with the changing unit. The recovery ECU performs substitute driving instead of the failed ECU to supply the current to the consumer.
    • 控制系统具有常规ECU和恢复ECU。 每个常规ECU分别控制当前消费者的驱动,通过驱动方式驱动并通过输出通道连接。 恢复ECU分别具有输出驱动器,其基于与各驱动方法相对应的驱动方法和通道切换块产生驱动电流。 当接收到指示一个常规ECU的输出通道的故障的信息时,恢复ECU指定故障通道的驱动方法,控制指定驱动方法的驾驶员产生驱动电流,并且控制指定的驱动方法的变化块 选择一个输出通道,通过故障通道连接故障ECU的当前使用者也与变更单元连接。 恢复ECU执行替代驾驶而不是故障ECU向消费者提供电流。

    • In a keyless entry system, when at least one proper portable unit is detected outside of a passenger compartment and the one is not detected inside of the passenger compartment, a door lock control is performed. Then, when it is determined that another proper portable unit is inside of the passenger compartment, the another proper portable unit is assigned to an unavailable proper portable unit. Further, it is determined whether at least one proper portable unit is inside of the passenger compartment while excluding the unavailable proper portable unit in response to an operation starting instruction to start an operation of a power source for driving the vehicle. When it is determined that no proper potable unit is inside of the passenger compartment, it is prohibited to start the operation of the power source.
    • 在无钥匙进入系统中,当在乘客室外检测到至少一个适当的便携式单元,并且在乘客舱内部没有检测到时,执行门锁控制。 然后,当确定另一个正确的便携式单元在乘客舱内时,另一适当的便携式单元被分​​配给不可用的适当的便携式单元。 此外,响应于开始用于驾驶车辆的电源的操作的操作开始指令,确定至少一个正确的便携式单元是否在乘客舱内,同时排除不可用的适当便携式单元。 当确定乘客舱内没有适当的饮用机组时,禁止开始电源的运行。

    • 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.
