Abstract
An anomaly detector includes a writing unit that writes anomaly detection data readable by an external diagnostic device to an external memory when an anomaly is detected in an on-board device. Further, the anomaly detector includes a determination unit that determines whether a failure is occurring in a memory, which is used when a processor is operated during the writing unit performs the writing. Also, the anomaly detector includes a resetting unit that resets the memory by activating a specified one of reset functions of the processor when the determination unit determines that a failure is occurring in the memory. When the determination unit determines that a failure is occurring in the memory, the writing unit writes the anomaly detection data after the memory is reset by the specified one of the reset functions.
Claims5
An anomaly detector, comprising:
- a writing unit that writes anomaly detection data readable by an external diagnostic device to a storage device when an anomaly is detected in a detection subject;
- a determination unit that determines whether a failure is occurring in a memory that is used when a processor is operated during the writing of the anomaly detection data by the writing unit;
- and
- a resetting unit that resets the memory by activating a specified one of reset functions of the processor when the determination unit determines that a failure is occurring in the memory,
- wherein when the determination unit determines that a failure is occurring in the memory, the writing unit writes the anomaly detection data after the memory is reset by the specified one of the reset functions,
- wherein the specified one of the reset functions is a dedicated reset function used only when the determination unit determines that a failure is occurring in the memory.

- wherein when the determination unit determines that a failure is occurring in the memory, the writing unit writes the anomaly detection data after the memory is reset by the specified one of the reset functions,
- wherein the writing unit determines whether the memory has been reset by the specified one of the reset functions by checking a special function register that stores an input from the specified one of the reset function.
