Abstract
A tire localization method for a vehicle, can include: 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 representing a received signal strength indication of a first radio frequency signal sent by the first Bluetooth module in each tire; acquiring an angle of arrival of the first Bluetooth module in each tire relative to the second Bluetooth module; and locating each tire based on the first data and the angle of arrival.
Claims18
A tire localization method for a vehicle, the method comprising:
- a) matching a first Bluetooth module in each tire of the vehicle with a second Bluetooth module of a Bluetooth host in the vehicle;
- b) acquiring first data representing a received signal strength indication of a first radio frequency signal sent by the first Bluetooth module in each tire;
- c) acquiring an angle of arrival of the first Bluetooth module in each tire relative to the second Bluetooth module;
- d) locating each tire based on the first data and the angle of arrival;
- e) sorting the first data corresponding to each tire;
- f) determining whether a tire belongs to a front tire group or a rear tire group by determining tires corresponding to two larger first data and two smaller first data, respectively;
- and
- g) determining whether a tire is a left tire or a right tire by comparing the angle of arrival of the first Bluetooth module relative to the second Bluetooth module in the front tire group or the rear tire group.
A tire localization method for a vehicle, the method comprising:
- a) matching a first Bluetooth module in each tire of the vehicle with a second Bluetooth module of a Bluetooth host in the vehicle;
- b) acquiring first data representing a received signal strength indication of a first radio frequency signal sent by the first Bluetooth module in each tire;
- c) acquiring an angle of arrival of the first Bluetooth module in each tire relative to the second Bluetooth module;
- d) locating each tire based on the first data and the angle of arrival;
- e) determining whether a tire belongs to a left tire group or a right tire group according to the angle of arrival of the first Bluetooth module in each tire relative to the second Bluetooth module;
- and
- f) determining whether a tire is a front tire or a rear tire by comparing the first data representing the received signal strength indications of the first radio frequency signals sent by the first Bluetooth modules of two tires in the left tire group or the right tire group.
A tire pressure monitoring apparatus installed in each tire of a vehicle, the apparatus comprising:
- a) a first Bluetooth module configured to communicate with a second Bluetooth module of a Bluetooth host in the vehicle;
- b) wherein localization of tires in the vehicle are realized according to an angle of arrival of the first Bluetooth module in each tire relative to the second Bluetooth module and first data representing a received signal strength indication of a first radio frequency signal sent by the first Bluetooth module in each tire;
- c) wherein the first Bluetooth module has at least one antenna and supports Bluetooth 5.1 and above protocols;
- d) sorting the first data corresponding to each tire;
- e) determining whether a tire belongs to a front tire group or a rear tire group by determining tires corresponding to two larger first data and two smaller first data, respectively;
- and
- f) determining whether a tire is a left tire or a right tire by comparing the angle of arrival of the first Bluetooth module relative to the second Bluetooth module in the front tire group or the rear tire group.
