Latest Patents
Hayasaka holds a patent for a "Control device and failure determination method." This invention allows for the determination of a failure phase of an AC current sensor without the need for a DC current sensor. The control device manages a motor through an inverter circuit that converts direct current into three-phase alternating current. It features a current sensor that detects the alternating current of each phase at the inverter circuit's output. The control device calculates estimated DC current values using the duty value of a PWM signal and the AC current values of two phases detected by the current sensor. It can determine a failure of the current sensor based on changes in the estimated DC current values.
