Abstract: Mining dump trucks are widely used in open-pit mines for the transportation of coal, ore and other materials due to their “Super heavy load transportation task and high driving speed” characteristics. In view of the practical problems such as limited power performance, poor fuel economy and serious exhaust emission existing in the traditional drive systems of classic two axle mine trucks and wide body mine dump trucks, a new type of wheel-axle cooperation hybrid system is proposed and its control strategy is studied in view of the super power demand and high power economy requirements of the power system of the open-pit dump truck due to the heavy-duty development. First of all, a new type of wheel-axle hybrid drive system with “the center axle is driven by a diesel engine and the front and rear axles are driven by motors” is designed, and eight working modes are studied and formulated; Secondly, the typical driving conditions of mining dump truck are analyzed, the road spectrum data collection experiment of cycle is carried out, and the special cycle curve of open-pit mine is established; Thirdly, the mode switching and torque distribution schemes of the wheel-axle cooperative hybrid power system under different hybrid modes are analyzed and determined, and the vehicle control strategy model based on the logical threshold of torque is built using Matlab / Simulink; Finally, the wheel-axle cooperative hybrid electric mine car model is built in CRUISE software, and after the control strategy is imported, the joint simulation test is carried out to compare and analyze the dynamic economic performance of the vehicle and the lifting effect of the traction weight. The results show that with the performance improvement scheme, the maximum speed and maximum climbing gradient at full load are increased by 29.51% and 54.36% respectively, the acceleration time of 0-30km/h and the comprehensive fuel consumption of 100 km are reduced by 82.30% and 56.29% respectively, the working characteristics of the engine, motor and capacitor are better, and the dynamic performance and economic performance of the whole vehicle are greatly improved; If the load increase scheme is adopted, the load of the whole vehicle can be increased by 21.54% after the hybrid transformation. The maximum speed and maximum climbing gradient at full load are increased by 28.60% and 52.31% respectively, while the acceleration time of 0-30km/h and the comprehensive fuel consumption of 100 km are reduced by 77.09% and 42.15% respectively.
