Method, device and equipment for detecting vehicle yaw based on trajectory data and medium

Abstract

The invention discloses a method, a device and equipment for detecting vehicle yaw based on trajectory data and a medium. The method comprises the following steps of acquiring a starting place and a destination of a to-be-navigated route, querying historical driving routes which are the same as the starting place and the destination, and forming a navigation route database by using the queried historical driving routes, matching the vehicle with the historical driving route in the navigation route database to obtain the historical driving route matched with the vehicle, navigating the vehicle based on the historical driving route matched with the vehicle, and according to the current position of the vehicle, setting an electronic fence in a preset range of the navigation route, and if the vehicle leaves the electronic fence and cannot be matched with all historical driving routes in the navigation route database, determining that the vehicle is yawed. According to the method, navigation of the vehicle can be realized only according to the trajectory data reported by the vehicle machine, whether the vehicle is yawed or not can be detected, additional equipment does not need to be additionally arranged, and the yaw judgment accuracy is greatly improved.

Description

Technical field [0001] The present invention relates to the field of vehicle navigation technology, particularly to a method based on the trajectory data of the detected vehicle yaw, means, devices and media. Background technique [0002] Now the user using the terminal navigation software to navigate driving more and more common, providing convenience for the user to navigate through the driver. [0003] During navigation, yaw is very important to identify user navigation experience, in the case of the user deviates from the planned route, need early and accurate identification of the yaw, then the user can plan a new route, accurate, timely guide the user driving. Current yaw commonly used recognition method, basically determination analysis, this method requires the installation of one or more of precision equipment, the cost is relatively high, it is difficult to promote the implementation based on a radar sensor or capture device based on the video image data. Inventive con...

AI Technical Summary

Problems solved by technology

At present, the commonly used yaw recognition methods are basically based on the analysis and judgment based on the data collected by radar sensors or video image equipment. This method requires the installation of one or more sophisticated equipment, and the cost is relatively high, so it is difficult to popularize and implement.
