Latest Patents

Yoshida's latest patents focus on innovative electric power steering devices. The first patent describes an electric power steering device that includes a phase advance correction unit. This unit is designed to advance the phase of a steering torque signal detected by a torque sensor. The device also features a specific frequency extraction unit that extracts components in a specific frequency band from the steering torque signal. Additionally, a gain multiplication unit corrects the steering torque signal to ensure it reaches a limit value set by a limiter. An addition unit then adds an assist correction command value to the assist command value based on the output from the gain multiplication unit.

The second patent also pertains to an electric power steering device. It includes a basic return command value calculation unit that calculates a return command value to bring the steering wheel back to a neutral position. A turn/return determination unit assesses the steering wheel's movement, while a gradually changing return command value calculation unit computes a return command value that gradually increases. This return command value is then added to the basic return command value to drive the electric motor effectively.
