摘要： The present disclosure provides a left and right wheel determination method, a wheel pressure monitoring chip and system, and related apparatuses. The left and right wheel determination method includes: obtaining a time duration for a wheel to rotate for a predetermined number of revolutions after the wheel being detected as rotating; sampling centrifugal acceleration and tangential acceleration of the wheel within the time duration; determining an overrun-lag relationship between the centrifugal acceleration and the tangential acceleration of the wheel based on a serial number of a sampling time-point corresponding to the centrifugal acceleration and a serial number of a sampling time-point corresponding to the tangential acceleration; and determining the wheel to be of a left wheel or a right wheel based on the overrun-lag relationship between the centrifugal acceleration and the tangential acceleration of the wheel.

摘要： A method for sampling wheel acceleration, a method for determining rotation angular position of a wheel, and a tire pressure monitoring system are disclosed. The method for sampling wheel acceleration may include: acquiring a real-time wheel acceleration value of a target wheel and calculating a time length required to rotate for a preset number of revolutions of the target wheel according to a first association relationship between the wheel acceleration and the time length required to rotate for the preset number of revolutions of the target wheel; obtaining a time interval between any two adjacent sampling points according to the time length required to rotate for the preset number of revolutions; and sampling the wheel acceleration of the target wheel once every the time interval starting from any time.
