Vehicle positioning data acquisition method and device

Abstract

The invention provides a vehicle positioning data acquisition method and device. The vehicle positioning data acquisition method comprises the steps that the effective GPS data and the current GPS data of a first vehicle are acquired; when the current GPS data are ineffective or a level precision factor is greater than a set threshold, communication equipment in the communication range of the first vehicle is detected; the GPS data of the communication equipment and distance information of the communication equipment and the first vehicle are acquired; and the positioning data of the first vehicle are calculated and outputted according to at least one parameter of the effective GPS data, the GPS data of the communication equipment and the distance information. According to the vehicle positioning data acquisition method and device, calculation is performed based on the communication equipment in the communication range of the vehicle and dead reckoning is performed according to the effective GPS data of the vehicle when a vehicle-mounted GPS module fails to work and a GPS antenna is damaged so as to accurately provide the positioning data of the vehicle in real time.

Description

technical field [0001] The invention relates to the field of vehicle networking communication, in particular to a method and device for acquiring vehicle positioning data. Background technique [0002] With the development of the automobile industry and the increasing complexity of urban roads, installing a Global Positioning System (GPS) on vehicles has become the choice of more and more vehicles. GPS is a satellite positioning device, which locates the access point through satellites, so as to know the location of the access point. During the driving process, the vehicle can know the vehicle's orientation and navigation information in real time through GPS. The use of GPS has brought a lot of convenience to travel. [0003] In the prior art, the vehicle-mounted satellite positioning device is mainly used in the field of car navigation. As long as the vehicle user enters the destination into the GPS, the GPS can obtain the location information of the vehicle in real time ...

Problems solved by technology

[0004] However, in the prior art, because the acquisition of vehicle positioning data depends on the vehicle-mounted GPS module, when the vehicle-mounted GPS module fails and the GPS antenna is damaged, the GPS module cannot work normally and cannot obtain vehicle positioning data, which makes it impossible to use GPS alone for navigation and positioning. Continuously provide navigation and positioning information for moving vehicles; at the same time, when the positioning data error of the GPS module is too large for the vehicle user to find, the vehicle positioning data is inaccurate, resulting in errors in the navigation information, which has brought great harm to the vehicle user. troubled
