Abstract:
A system for monitoring pulse width modulation (PWM) duty operation execution for motor control, which can detect whether or not the PWM duty operation execution used for torque and speed control of a motor is performed normally within an interrupt execution timing, and perform failure diagnosis depending upon the detected result, thus enhancing stability of motor control.

Claim (Index 1):
A system for monitoring pulse width modulation (PWM) duty operation execution for motor control, the system comprising:\n a motor control unit for operating a PWM duty for motor control, and outputting a confirmation signal of the PWM duty operation execution for determining whether or not the PWM duty is updated normally to a detection and failure diagnosis circuit; and the detection and failure diagnosis circuit for outputting a failure determination signal for determining whether or not the operation execution and update of the PWM duty are performed normally within a PWM duty update reference timing based on the confirmation signal of the PWM duty operation execution wherein the detection and failure diagnosis circuit comprises:\n a clock PLL circuit for receiving a clock signal from an external oscillator to generate a clock signal required for a counter generator; \n the counter generator for receiving a PWM duty operation execution signal outputted from the digital output section of the motor control unit and the clock signal outputted from the clock PLL circuit to generate and output a first counter signal and a second counter signal required for failure determination for the PWM duty operation and update; and \n a failure determination circuit for outputting a first failure determination signal and a second failure determination signal as a signal for determining whether or not the PWM duty operation execution and update fails based on the first counter signal and the second counter signal outputted from the counter generator.
