摘要：
Aiming at the rough control for hydraulic pump displacement in creep mode of hub-motor hydraulic auxiliary driving vehicle, a creep control method is proposed. The idea of speed ratio control of continuously variable transmission is adopted to achieve the displacement control of hydraulic pump. A simulation platform of hub-motor hydraulic driving vehicle is constructed with AMESim software, and the response characteristics and effects of the creep mode control method are verified. Simulation shows that the creep mode control method can realize continuous control of speed ratio within the working range of the hydraulic system, and the best economical operation of the vehicle is achieved via adjusting the working point of the engine. © 2019, Editorial Office of Journal of Xi'an Jiaotong University.
