Abstract:
1. An electronic control unit comprising: a microcomputer that performs processing for controlling a control target; and an IC that monitors operation of the microcomputer, wherein: the microcomputer includes a test selection means for selecting a test to verify functions of the microcomputer, and runs the test selected and transmits a test result indicating a result of the test to the IC; the IC determines correctness/incorrectness of the test result transmitted from the microcomputer; the IC transmits to the microcomputer a verification result, which is a result of checking whether the test result is correct or incorrect; the microcomputer transmits a test ID, which is identification information of a test run of this time, to the IC along with the test result; and the IC sets an expected value of the test result from the microcomputer, based on the test ID from the microcomputer, and compares the expected value with the test result to check whether the test result is correct or incorrect.
