Tire pressure monitoring module, tire localization system and tire localization method

A tire localization method for a vehicle, comprising:

• matching a first Bluetooth module in each tire of the vehicle with a second Bluetooth module of a Bluetooth host in the vehicle;
• acquiring first data sent by the first Bluetooth module in each tire, wherein the first data comprises data representing components of magnetic field intensity in at least two different directions in a corresponding tire;
• obtaining an angle of arrival of the first Bluetooth module in each tire relative to the second Bluetooth module;
• locating each tire based on the first data and the angle of arrival;
• and
• determining, for each of the tires, whether a tire belongs to a front tire group or a rear tire group based on the angle of arrival of the first Bluetooth module in each tire relative to the second Bluetooth module;
• wherein in a case where a straight line formed by the two antennas of the second Bluetooth module is parallel to a longitudinal direction of a body of the vehicle,
• the corresponding tire is determined to belong to the rear tire group in response to an absolute value of the angle of arrival being less than 90 degrees;
• and
• the corresponding tire is determined to belong to a front tire group in response to the absolute value of the angle of arrival being greater than 90 degrees;
• or
• in a case where a straight line formed by the two antennas of the second Bluetooth module is perpendicular to a longitudinal direction of a body of the vehicle,
• the corresponding tire is determined to belong to the rear tire group when the angle of arrival is a negative value;
• and
• the corresponding tire is determined to belong to a front tire group when the angle of arrival is a positive value.
