Title:
ELECTRONIC CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2022064425
Kind Code:
A
Abstract:
To provide an electronic control device capable of measuring the accurate load factor of the task with respect to the reference time.SOLUTION: The electronic control device performs load measurement of a CPU 6 including a scheduled processing to execute on time and a series of interrupt processing an interrupt request which is received from the interrupt processing source, and switches from a normal logic mode to a simple logic mode depending on the measurement result. The electronic control device executes the load measurement at the start of the scheduled processing, and when the start time is delayed by the interrupt processing, calculates the load factor by subtracting the delay caused by the interrupt processing from the load measurement of scheduled processing.SELECTED DRAWING: Figure 4
