The invention discloses a distributed drive-by-wire wheel edge driving system and method for a pure electric mining dump truck. The distributed drive-by-wire wheel edge driving system comprises a distributed drive-by-wire driving system, a composite energy system and a power switching system. The advantages of pure electric drive and distributed drive-by-wire drive are integrated, and on the basis that the loading capacity of the mining dump truck is increased, the problems that in the transmission process of a diesel-electric transmission system of the mining dump truck, energy is converted multiple times, loss is large, power distribution is unreasonable during starting, climbing and loading, and power consumption is low can be solved. The problems of brake energy loss and waste, high mechanical part fault occurrence risk, relatively high maintenance cost, serious exhaust emission and the like are solved; the advantages of an energy supply mode of a power battery and a super capacitor on energy management are used for recovering and reusing braking energy and optimally designing a whole vehicle control strategy, so that the driving efficiency of the whole vehicle can be effectively improved.
