A smart multi-car elevator system, comprising at least two hoistways, a switch mechanism, a power mechanism and multiple cars; the hoistways are internally provided with rails for the movement of the cars, the switch mechanism is provided between adjacent hoistways, the position of the cars being switched, by means of the switch mechanism, between the adjacent hoistways; the perform, driven by the power mechanism, upward or downward movement within the hoistways or switch movement between the hoistways, and the cars are driven by the power mechanism to stop at any floor for people to get in or get out the elevator. The smart multi-car elevator system is provided with multiple individually running cars within one hoistway, improving the conveying efficiency and effectively saving the building space and building cost.
