Latest Patents
One of his latest patents is a vehicle steering apparatus that utilizes steer-by-wire (SBW) technology. This invention aims to downsize an expensive turning-power motor by mechanically separating the steering mechanism from the turning mechanism for road wheels. The turning-power motor adjusts the road wheels based on a turning angle-steering angle ratio, which is influenced by the vehicle's speed. This ratio increases with speed until a predetermined value is reached, after which it decreases, optimizing steering performance.
Another notable patent is for a steering handle designed for comfort and ease of use. In this design, the axis of the steering shaft is inclined to be higher in the forward direction of the vehicle body. The left and right grips can rotate in opposite directions, allowing the driver to maintain a natural posture while steering. This design prevents unnatural wrist twisting and facilitates a smoother steering operation.
