Abstract

It is possible to perform an appropriate recovery processing according to a state of power supply failure. When a system reset has occurred, the system operation state immediately before it is stored in an operation state memory (1) of a storage section (102) and a recovery mode determined according to the stored operation state is stored in a recovery mode memory (2). At the beginning of the recovery processing, necessary processing is performed according to the recovery mode stored. On the other hand, each time recovery processing is performed, counting is performed by a recovery counter (5) while the system normal operation time is counted by a timer counter (6) for normal operation time. According to the counting value and the normal operation time of the counters, processing such as system stop and engine reset is performed.

Description

technical field [0001] The present invention relates to an operation recovery control method of various electronic equipment, equipment, etc. when a system reset occurs due to an abnormal operation of the electronic equipment, equipment, etc., especially a recovery control method in a vehicle control system. Background technique [0002] In the electronic control system, the following device is known. When the system is reset, for example, when the system is reset due to an abnormal power supply, in order to quickly restore the operating state before the abnormality occurs, the stored information about the The stored data in the backup memory of various data in the system operation is set so that the pre-update data and the post-update data of the stored data can be distinguished, and the necessary stored data can be easily selected when restoring, and the restoration process can be performed smoothly ( For example, refer to Patent Document 1). [0003] In addition, in such...
