Based on the theory of hydraulic brake system of traditional mining vehicles, under the safety situation, based on the maximum recovery of regenerative braking energy of hybrid mining vehicles, a regenerative braking force distribution and regeneration system for rear-wheel parallel hybrid mining vehicles is proposed for dynamic control strategy.Mainly considering the effects of motor power generation efficiency, battery System and Organization Control(SOC) value and braking force distribution on the recovery of regenerative braking energy, ADVISOR was used for vehicle modeling and simulation under typical mine braking conditions.The results show that the maximum regenerative braking energy recovery efficiency at the initial braking speed of 15 km/h and the braking strength Z of 0.1, 0.3, and 0.5 is 65.01%, 55.99%, and 46.41%, respectively. The regenerative braking control strategy of the rear-drive parallel-mixing mining vehicle is used to solve the problem of braking safety performance and to maximize the recovery efficiency of regenerative braking.
