1. A method for self-positioning tires implemented by a receiver in a vehicle, wherein a first positioning circuit is provided in the receiver, an emitter is provided in each tire of the vehicle and a second positioning circuit is provided in each emitter respectively, the method comprising:

  • acquiring first position information detected by the first positioning circuit;

    acquiring second position information of each emitter respectively via the corresponding second positioning circuit; and

    acquiring corresponding relative position information respectively between the receiver and each emitter based on the first position information of the receiver and the second position information of each emitter;

    wherein the step of acquiring second position information of each emitter respectively via the corresponding second positioning circuit, comprises;

    transmitting a first control instruction to each emitter respectively by the receiver in a first communication mode, so that the each emitter controls the corresponding second positioning circuit to power on according to the first control instruction; and

    receiving the second position information respectively transmitted in a second communication mode by each emitter and acquired via the powered-on second positioning circuit;

    wherein the first communication mode works in a first frequency, the second communication mode works in a second frequency, and the first frequency is lower than the second frequency.
