PROBLEM TO BE SOLVED: To provide a clock monitor device that can appropriately detect a clock anomaly.SOLUTION: An ASIC 1 has an oscillator 11 for generating an ASIC clock signal CLK1, and an MCU clock monitor section 13 for monitoring an MCU clock signal CLK2 for an anomaly. An MCU 2 has an oscillator 21 for generating the MCU clock signal CLK2, and an ASIC clock monitor section 23 for monitoring the ASIC clock signal CLK1 for an anomaly. Such clock monitor functions can be executed on external independent chips to monitor mutual ECU internal clocks. |
