Latest Patents

Yamazaki’s listed patents address control and diagnostics in mechanical systems.

- **Vehicle traction control system.** This invention coordinates a traction control unit with front and rear motor control units. The traction control unit sets a threshold axle speed between a target axle speed and vehicle speed, then sends axle speed information to the motor control units. Those units use the information to control their respective rotating electric machines and help eliminate wheel slip.

- **Stretch detection system for power transmission mechanism.** This system assesses stretch in a conveyor’s power transmission mechanism by analyzing the motor-current signal in the frequency domain. It calculates an integral value over a frequency range associated with sideband waves, then uses that value to diagnose the mechanism’s stretch condition and output a result.
