Latest Patents

He Bao holds a patent for a hydraulic working machine. This machine features an assist electric motor connected to an engine and a hydraulic pump. The design minimizes emissions of air pollutants in the exhaust gas from the engine, regardless of fluctuations in the load torque of the hydraulic pump. A specific revolution speed suitable for reducing emissions is stored, and the engine is controlled using this speed as a target. The absorption torque of the hydraulic pump undergoes high-pass filtering to obtain a high-frequency component devoid of a trend component. Target assist torque is computed from this high-frequency component, allowing for power running and generation control of the assist electric motor. Additionally, a specific output torque range suitable for reducing emissions is stored, and the target assist torque is corrected to ensure that the trend component does not exceed this range.
