An intelligent fabric includes: a base layer provided with vent holes and a thermal insulation layer arranged on the base layer and moved relative to the base layer; a temperature sensor configured to detect temperature information; and a controller connected to the temperature sensor and the thermal insulation layer, and configured to control the thermal insulation layer to be moved relative to the base layer in accordance with the temperature information detected by the temperature sensor, to switch the thermal insulation layer between a state where the thermal insulation layer covers the vent holes completely and a state where the thermal insulation layer does not cover the vent holes, or among the above two states and a state where the thermal insulation layer covers a portion of the vent holes.
