Title: Innovations of Hidekazu Nagase
Introduction
Hidekazu Nagase is a prominent inventor based in Hirakata, Japan. He has made significant contributions to the field of vehicle technology, holding a total of 12 patents. His work focuses on enhancing operational efficiency and accuracy in various applications.
Latest Patents
One of his latest patents is a vehicle speed detection system. This system corrects errors caused by the pitching movement of a vehicle with high accuracy and at a low cost. The ground speed of the vehicle, sensed by a Doppler sensor, is corrected using angular velocities relative to the vehicle's center of gravity. The system takes into account the center of rotation of the vehicle and the rotation of the Doppler sensor itself during the vehicle's pitching movement. Additionally, the arrangement allows for the Doppler sensor to be mounted at a high level without increasing its output power. A look-up table stores the relationship between the actual installation level of the Doppler sensor and a reference installation level, enabling accurate calculations of the beam depression angle.
Another notable invention is a dozing device for bulldozers. This dozing system enhances operational efficiency during dozing operations and ensures a smooth excavation face. When operating in an automatic digging mode, the system determines if the load on the blade is stable. It then corrects the target position for the cutting edge relative to the ground based on the actual position at that time. The system also switches between different weight characteristics for load control and smoothing control, depending on the ratio of excavated soil to the blade's loading capacity.
