This invention discloses a hydraulic steering device and an all-terrain vehicle hydraulic steering system. The steering gear 6 of the hydraulic steering device adjusts its displacement via a variable displacement control cylinder 9, which is controlled by an electro-proportional two-position three-way directional valve 11. The opening of the oil circuit within the electro-proportional two-position three-way directional valve 11 is controlled by an electrical signal converted from vehicle speed. When the vehicle speed increases, the displacement of the steering gear 6 decreases; when the vehicle speed decreases, the displacement of the steering gear 6 increases. The outlet of the variable displacement pump 1 is connected to a steering oil circuit switching valve 7 via a one-way valve 4. The steering oil circuit switching valve 7 connects the steering gear 6 and the steering cylinder 3. This invention addresses the problem of easy rollover and fishtailing in hydraulically driven all-terrain vehicles at high speeds by providing a hydraulic steering control system that links vehicle speed and steering wheel angle control, adjusting the control ratio of steering wheel angle and overall vehicle angle according to vehicle speed.

This invention relates to the field of automatic control of nitrogen valves, and particularly to an automatic control method for nitrogen valves based on intelligent sensing. First, based on the measured values ​​of the acquired original sensing variables, preprocessing is performed to obtain preprocessed measured values ​​of the sensing variables. Based on the preprocessed measured values ​​of the sensing variables, a time-varying energy consistency fusion algorithm is used to obtain the state-driven energy value of the sensing variables. Based on the state-driven energy value of the sensing variables, the contribution of the sensing variables is determined, and a fusion situation indicator is constructed. Then, based on the fusion situation indicator, a control potential energy function is constructed using a continuous potential energy-driven valve position decision algorithm. Based on the control potential energy function, the valve adjustment speed is obtained. This method solves technical problems such as insufficient utilization of multi-source sensing information, inaccurate state assessment, delayed adjustment response, and lack of effective intervention for abnormal risks.
