Tire location positioning method and apparatus and tire pressure monitoring system

A tire location positioning method, applied to an automobile, the automobile comprising a tire pressure monitoring system (TPMS) receiver, wherein the method comprises:

• receiving an excitation signal;
• generating a response signal according to the excitation signal, wherein the response signal comprises signal strength information, the signal strength information being used for representing signal strength of receiving the excitation signal;
• determining, according to the signal strength information, a delay time for the generated response signal;
• and
• sending the response signal to the TPMS receiver according to the delay time, wherein the delay time t is calculated by a formula of t=k*p, k is a natural number, p is the corresponding to signal strength.

A tire pressure monitoring system (TPMS) receiver, comprising:

• at least one processor;
• and
• a memory that is communicatively connected to the at least one processor, wherein
• the memory stores an instruction executable by the at least one processor, the instruction, when executed by the at least one processor, enabling the at least one processor to control the first exciter to send the first excitation signal, and controlling the second exciter to send the second excitation signal, wherein a time when the first excitation signal is sent is different from a time when the second excitation signal is sent;
• respectively receive response signals that are generated according to the first excitation signal or the second excitation signal by all the tire pressure sensors, wherein the response signals comprise signal strength information, the signal strength information being used for representing signal strength of receiving the first excitation signal or the second excitation signal;
• perform positioning on front and rear wheels according to times when the response signals are received, to identify response signals sent by tire pressure sensors of the front and rear wheels;
• and perform positioning on left and right wheels according to the signal strength information, to identify response signals sent by tire pressure sensors of the left and right wheels;
• wherein, each of the response signals is transmitted by a tire pressure sensor according to a delay time, the delay time is determined according to a corresponding signal strength, the delay time t is calculated by a formula of t=k*p, k is a natural number, p is the corresponding to signal strength.
