  • Patent number: 9110842
    Abstract: A control device for a vehicle including a nonvolatile memory which is electrically erasable and writable detects, on start-up, whether or not an error occurs in updated data read from the nonvolatile memory, and when an error has been detected, performs a reset after saving error information. When being restarted by the reset, the control device for a vehicle determines on the basis of the error information whether or not there is updated data in which an error has occurred, and when there is updated data in which an error has occurred, overwrites the updated data with a fixed value prior to the error detection. Accordingly, there can be suppressed a case in which the error detection is performed while the updated data with an abnormality is present causing the reset and the error detection to be repeated.
