Abstract
Distributed drive electric mining trucks’ active safety and driving economy are inseparably associated with chassis integration control. In order to ensure the safety and economy of mining trucks under complex and variable working conditions, the key technologies and research development of chassis integration control for distributed drive electric mining trucks are overviewed in terms of truck handling stability control, dynamics integration control, and chassis fault-tolerance control, and energy-saving control. Aiming at the longitudinal instability, yaw, roll, and pitch of mining trucks, the truck longitudinal, lateral, and vertical stability control methods are described comprehensively, and the coupled and integrated control strategies between the systems are compared. Distributed drive electric vehicle chassis cooperative fault-tolerant control methods are outlined, and the effectiveness of chassis cooperative fault-tolerant control applied to mining trucks is demonstrated. Regarding the feedback energy to improve the economy of distributed drive electric mining trucks, an electro-hydraulic brake energy recovery method combining anti-lock brakes and hydraulic brakes is summarized, coupled with lateral and vertical dynamics. Furthermore, the torque distribution method that considers the truck driving stability and improves the driving economy is overviewed systematically. Finally, the development prospects of the chassis integrated control of distributed drive electric mining trucks are foreseen.
