The linear taper clutch type self-adaptive automatic speed change electric drive axle comprises a first half shaft, a second half shaft and a differential mechanism which are coaxially arranged, a power motor and a speed change assembly are both installed on the first half shaft and arranged in a linear mode, the structural compactness is extremely high, and the linear taper clutch type self-adaptive automatic speed change electric drive axle is suitable for application scenes with extremely strict requirements for installation space. And meanwhile, the expansibility of the structure is excellent, various functional modules such as human-controlled reversing, inertial reversing and active upshift and downshift according to real-time power can be flexibly expanded according to actual requirements, and the design requirements of platformization and modularization are met. Moreover, the motor can always work efficiently in the current high-efficiency area according to the change of the driving intention, a multi-parameter control strategy with the consciousness and intention of people as priority is realized, harmony and unification of people, vehicles, roads and running resistance/running load are realized, and the driving safety is improved. The important scientific and engineering technology common key problem of traction/driving force-running resistance/load efficient and accurate balance control is solved.
