The invention discloses a self-generating intelligent tire system and a whole vehicle stability control method based on the system, a signal acquisition module is used for acquiring an electric signal of a sensor assembly, the acquired electric signal is transmitted to a filtering module for filtering processing, and the processed signal is transmitted to a whole vehicle ECU through a Bluetooth signal transmitting module; when a tire rolls, the induction coil cuts magnetic induction lines of the vehicle-mounted magnetic field transmitting module to generate current, the current is rectified through the power generation module of the signal processor, and electric energy needed by work is provided for the signal processor. The intelligent tire provided by the invention can realize self-power generation in the vehicle driving process, provides the functions of road surface identification, tire load estimation and accurate measurement of tire mechanical parameters, provides data for stability control of the whol
