Intelligent bicycle for automatically correcting longitudinal deviation of millimeter wave radar and calibration method thereof

Abstract

The invention provides an intelligent bicycle for automatically correcting a longitudinal deviation of a millimeter wave radar and a calibration method thereof, wherein the intelligent bicycle and themethod relate to the field of the bicycle. The intelligent bicycle comprises a bicycle body and an intelligent control device which is mounted on the bicycle body. The intelligent control device comprises a millimeter wave radar, an acceleration sensor and a processor. The acceleration sensor is connected with the millimeter wave radar and is used for measuring the acceleration of the millimeterwave radar in a vertical direction. The processor is electrically connected with the millimeter wave radar and the acceleration sensor. The longitudinal acceleration of the millimeter wave radar is measured through the acceleration sensor. Through the ratio between the measured acceleration and the gravitational acceleration, a longitudinal deviation angle of the millimeter wave radar is calculated. The gain of the millimeter wave radar in different measurement directions is compensated according to the longitudinal deviation angle, thereby effectively calibrating the longitudinal deviation ofthe millimeter wave radar and improving detecting precision.

Description

technical field [0001] The invention relates to the field of bicycles and control methods thereof, in particular to an intelligent bicycle and a calibration method for automatically correcting longitudinal deviations of millimeter-wave radars. Background technique [0002] At present, bicycles have become more and more popular means of transportation, and commuting to and from get off work and daily riding have become a healthy way of transportation favored by people. On a smart bicycle, a radar device is usually installed to measure the speed of the bicycle, or to monitor the surrounding environment, and provide safety reminders to vehicles behind, etc. When the radar device enters and exits the speed measurement or the surrounding environment monitoring, the radar device is installed by default or the radar directionality deviation will not occur during the movement of the bicycle. [0003] However, the radar device is generally installed on the body of the bicycle, and d...
