Latest Patents

Tanabe's latest patents include a valve timing control unit and a variable valve timing control device. The valve timing control unit features a mechanism that includes a driving rotary body, a driven rotary body, an electric motor, and a deceleration gear. This unit is designed to set the relative rotational phase of the driving and driven rotary bodies. It also incorporates a phase sensor unit that detects the actual phase of these components. The controller within the unit manages the electric motor to minimize the phase difference between the actual and target phases. Additionally, it includes a swing controller that adjusts the target phase when fluctuations are detected.

The variable valve timing control device consists of a phase detecting portion and a phase control portion that drives an electromagnetic solenoid. This device sets a spool to either a phase control region or a lock region based on detection signals. It also features a boundary memory portion that stores a boundary electric current value, which is essential for the operation of the phase control. The characteristic calculation portion calculates this boundary electric current value, ensuring optimal performance based on solenoid and valve characteristics.
