Title:
CONTROL DEVICE OF ELECTRIC POWER STEERING DEVICE
Document Type and Number:
Japanese Patent JP2009056820
Kind Code:
A
Abstract:
To provide a control device of an electric power steering device capable of measuring processing load of a CPU mounted in the power steering device of the electric power steering device without increasing the processing load of the CPU.
The device comprises a main MCU 100 having the CPU 101 for controlling a steering assist motor 20 and a monitoring MCU 150 for measuring the processing load of the CPU 101 of the main MCU 100. The main MCU 100 executes a task according to the priority based on the processing load of the CPU 101 measured by the monitoring MCU 150.
