Problems solved by technology

However, such a guidance method may cause the vehicle behind to catch up with the vehicle ahead because the speed of the vehicle in front is too fast, or the vehicle behind encounters a red light. As a result, the vehicle in front must turn around and wait for the vehicle behind, or It's because the vehicle behind couldn't catch up or lost track of the vehicle in front.
It can be seen that the current way of following a car is still quite time-consuming and inconvenient

Embodiment Construction

[0038] In order to allow the navigation device to correctly guide the user to track the moving target ahead, the present invention uses the mutual communication between the navigation device and the moving target to set the navigation device to follow the moving target, that is, the location of the moving target For the destination, update the route planned by the navigation device at any time. In this way, both parties can easily get on the road. The vehicle in front does not have to wait for the vehicle behind, and the vehicle behind does not have to be afraid of the vehicle in front leaving its sight and make dangerous actions such as overtaking or running a red light, which makes the entire driving process safer and smoother. The present invention is a set of tracking and navigation method, device and computer program product used based on the above concepts. In order to make the content of the present invention more clear, the following specific examples are given as exam...

Abstract

The invention discloses a method for tracing a moving target and a moving device for tracing the moving target. The method comprises the steps that first positioning information of the current position of the moving device is obtained; second positioning information of the current position of the moving target is obtained and second positioning information of the current position of the moving target is obtained again at regular time; according to the first positioning information, the position of the moving device is displayed; according to the second positioning information, the position of the moving target is displayed; according to the first positioning information and the second positioning information, the distance between the moving device and the moving target can be calculated; whether the distance exceeds the preset distance is judged; when the distance exceeds the preset distance, a warning message is sent.
