Accurate positioning method for motor driven vehicle driving

Abstract

The invention discloses a method for precisely positioning a vehicle as the vehicle travels. The method comprises the following steps: three-dimensional coordinates are formed by taking a vehicle-mounted GPS satellite receiving antenna as a three-dimensional origin and taking the length direction, the width direction and the height direction of the vehicle as three-dimensional axes respectively; the three-dimensional coordinates are adopted for storing dimensional parameters in terms of the length, the width and the height of the vehicle in a vehicle-mounted GPS or / and a traffic monitoring system; the traffic monitoring system uses the network RTK technology to receive and process data from a continuous navigation reference station, and so provides corrected reference data for positioning of the vehicle; the traffic monitoring system transmits the network RTK corrected reference data to the vehicle-mounted GPS; the vehicle-mounted GPS receives the corrected data and combines positioning data received by the vehicle-mounted GPS with the corrected data to seek data about precise positioning of the vehicle in a real-time manner; and based on information about the travelling state of the vehicle, the method can monitor how a driver drives the vehicle, and ensures that acts in defiance of traffic law are recorded and dealt with, and that drivers can sued for violation of the traffic law. As accurate positioning of the travelling vehicle can be carried out in a real-time manner, with the level of positioning being as precise as centimeter and even millimeter, the invention can ensure that the vehicle body of the vehicle travels on the road in a proper manner, thereby helping maintain a good traffic order.

Description

technical field [0001] The invention relates to a positioning method, in particular to a precise positioning method for a motor vehicle. Background technique [0002] Using intelligent transportation system to control and reduce the occurrence of traffic accidents and ensure traffic safety is the goal that people pursue. That is to say, through traffic monitoring systems such as testers, meters, cameras, electronic language traffic navigation maps, GPS positioning systems, electronic police platform vehicle terminals, etc. Carry out whole-process monitoring and recording, and promptly warn and deal with drivers, such as motor vehicle speeding, overloading, unlicensed driving, drunk driving, and fatigue driving. At the same time, it can also monitor and record the whole process of the driver not wearing a seat belt, using a mobile phone while driving, breaking the ban, and driving without following the traffic signs and markings, and give the driver a warning signal in time....
