Title:
LAP COUNTING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/048134
Kind Code:
A1
Abstract:
A lap counting method and device, which is applied to a non-motor vehicle, the non-motor vehicle having a torque sensor. The method comprises: acquiring torque sensor data in real time (S110); obtaining real-time torque data according to the torque sensor data (S120); obtaining a real-time torque data change period according to the real-time torque data (S130); and determining lap counting data according to the change period, wherein the lap counting gauge point is the peak value of the change period (S140). The technical problem in the prior art that the lap counting method is magnetic lap counting or acceleration lap counting, which is easily subject to the interference of the surrounding magnetic field or the larger fluctuation of acceleration data itself, thereby affecting the accuracy of lap counting, is solved. The technical effects that lap counting is performed by a periodic change of torque acting on a bicycle crank, so that data is stable and free from external factors, and the lap counting is stable and reliable, thus improving the accuracy, sensitivity and response speed of lap counting, and improving the adaptability of lap counting of a bicycle by using a changing trend for lap counting are achieved.
