Latest Patents

Yamamoto's latest patents include a motor control device and a shift range control device. The motor control device is designed to manage the drive of a motor within a motor drive system that includes a detent mechanism. This mechanism features a detent member that rotates with an output shaft, which transmits the motor's rotation. An engaging member moves a valley portion through the motor's rotation, positioning the output shaft by stopping within a designated range. The device incorporates a positioning determination unit that assesses whether the engaging member is correctly positioned, and an energization control unit that turns off the motor's power when the engaging member is in the correct position.

The shift range control device consists of a drive circuit, a voltage detector, and a controller. The drive circuit utilizes switching elements and is shared among multiple winding sets. The voltage detector monitors the terminal voltages of each phase, while the controller manages the energization of the winding sets by controlling the on and off operations of the switching elements. It also performs disconnection diagnosis based on terminal voltage during the energization of the winding sets.
