Abstract

The invention provides an automobile motion state detection method and system. The method includes: positioning the location of an automobile, acquiring the parking spot information according to a time order, and adding the parking spot information into a parking spot list in order; when the parking spot number of the parking spot list is greater than or equal to a preset number, connecting all 3 automobile parking spots with adjacent acquisition time in the parking spot list to compose parking spot included angles; and counting the number of parking spot included angles greater than or equal to a preset driving judgment angle, if the number of parking spot included angles is greater than or equal to a preset driving judgment number and the distance between an automobile parking spot acquired first and an automobile parking spot acquired last in the parking spot list is smaller than or equal to a preset slow driving judgment distance, determining that the automobile is in a slow driving state. The technical proposal provided by the invention can accurately determine whether the automobile is in a stop state or slow driving state.

Description

technical field [0001] The invention relates to the technical field of vehicle detection, and more specifically, to a method and system for detecting the motion state of a vehicle. Background technique [0002] Automotive GPS (Global Positioning System, Global Positioning System) positioning technology is widely used in the fields of vehicle positioning, navigation, and anti-theft. In order to realize the positioning of the car, it is often necessary to install a GPS vehicle antenna in the car, and transmit a communication signal to the GPS satellite through the vehicle antenna, so that the GPS satellite can determine the position of the car and other data according to the communication signal, and then the GPS satellite will include the position of the car The GPS positioning signal of the data is sent to the ground user equipment (such as a GPS receiver or server), and the ground user equipment analyzes and calculates the GPS positioning signal to realize the positioning o...
