Active hydro-pneumatic suspension has the characteristics of real-time control of body attitude and height, real-time adjustment of damping and stiffness parameters, good adaptability to road conditions, etc., which can make the vehicle always maintain good ride comfort and handling performance under different moving states or road conditions. With the rapid development of computer control technology and electronic technology, and people more and more high to the requirement of ride comfort, active suspension of oil and gas application in vehicle demand is increasing, especially in some poor driving conditions, large capacity of high-speed heavy chassis engineering vehicles, the traditional passive suspension of oil and gas is difficult to meet the requirements of the ride comfort, The use of active hydro-pneumatic suspension system to upgrade the ride comfort of vehicles has become a hot topic of current research. In this paper, the vehicle active suspension system of oil and gas is analyzed, the principle and characteristics, as well as the domestic and foreign high speed heavy-duty vehicle active suspension system of oil and gas comfort control summarizes and reviews the present situation and problems of research and application, in detail elaborated the commonly used control strategy for active suspension control of oil and gas, finally the high-speed heavy-duty vehicle active suspension system of oil and gas technology has made the outlook for the future development.
