摘要： PROBLEM TO BE SOLVED: To provide a data rewrite method for storage devices, which can write the same data as that which has been failed to be written when rewriting after write failure. SOLUTION: Identification data to identify the relations between control data originally written in a flash memory 3 and that to be newly written is written into an identification ID area 3c assigned in the head of the outside of a loader area 3a which is used to make communication data to reside in a storage area of the flash memory 3. Thereby, if a communication error occurs, the possibility that identification data has been successfully written is high. Therefore, when rewriting, it is determined that identification data on the flash memory 3 matches that for data to be newly written and data stored in the flash memory 3 is deleted to rewrite new data, so that the same data as that which has been failed to be written can be written.

摘要翻译：要解决的问题：提供用于存储设备的数据重写方法，其可以在写入失败后重写时写入与未写入的数据相同的数据。解决方案：用于识别最初写入闪速存储器3的控制数据与要被新写入的控制数据之间的关系的识别数据被写入分配在使用的装载器区域3a的外部的头部中的识别ID区域3c中以使通信数据驻留在闪速存储器3的存储区域中。因此，如果发生通信错误，则识别数据已被成功写入的可能性高。因此，当重写时，确定闪存3上的识别数据与新写入的数据相匹配，并且删除存储在闪速存储器3中的数据以重写新数据，使得与已经失败的数据相同的数据要写的可以写。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To monitor the presence/absence of abnormality in a clock for a program of a microcomputer.
SOLUTION: The time required for executing a wait time generation program, that is, a predetermined value of wait time is obtained. Subsequently, the wait time generation program is executed to measure the actually taken time, that is, the actual value of the wait time. In the case where the actual value of the wait time is larger than the predetermined value of the wait time, a program clock is determined to be abnormal.

摘要： PROBLEM TO BE SOLVED: To provide an engine control device for suppressing the fluctuation of torque during charging/releasing external load.
SOLUTION: A vehicle system has a generation control device for generating and charging a vehicle battery with the drive of a generator which is driven by an internal combustion engine to generate power. Herein, an output torque estimating device and a torque fluctuation estimating device are provided for estimating output torque generated by the internal combustion engine and for estimating torque fluctuation applied to the internal combustion engine with external load, respectively. When the torque fluctuation occurs such that the torque estimated by the torque fluctuation estimating device has a value larger or smaller than the output torque estimated by the output torque estimating device, generation load following generation is controlled by the generation control device.
