Embodiment 1

[0023] When the car-following navigation system is located in the second navigation device, the user operates the second navigation device to designate a first navigation device as a navigator device through the server, and sends the navigation device to the When the first navigation device sends a location request, the first navigation device executes step S11, that is, sends its own current location information to the second navigation device through the server in real time. Correspondingly, the car-following navigation system acquires the first position information of the first navigation device corresponding to the navigation in real time.

[0024] Wherein, the manner in which the user specifies a first navigation device as a navigator through the server includes but is not limited to: the user operates the second navigation device to provide the server with identification information of the first navigation device, The server may determine the first navigation device corr...

Embodiment 2

[0059] Such as image 3 As shown, when the car-following navigation system is located at the server, the car-following navigation system first determines that the first navigation device is located in the leading vehicle, and determines that the second navigation device is located in the following vehicle.

[0060] Specifically, the car-following navigation system may determine the first navigation device for navigating and the second navigation device for following by performing steps S21 and / or S22.

[0061] In step S21, the car-following navigation system, based on the navigation request including the navigation identification information from the first navigation device, will include the navigation identification according to the identification information of the second navigation device provided by the first navigation device The confirmation information of the information is sent to the second navigation device for confirmation; and then steps S23 and S24 are executed ac...

Embodiment 3

[0086] Such as Figure 4 As shown, when the car-following navigation system 11 is located in the second navigation device 1, the user operates the first communication module 111 to designate a first navigation device 3 as a navigating device through the server 2, and through The server 2 will send a location request to the first navigation device 3 , and the first navigation device 3 will send its own current location information to the first communication module 111 through the server 2 in real time. Then the first communication module 111 acquires the first position information of the first navigation device 3 corresponding to the navigation.

[0087] Wherein, the manner in which the user specifies a first navigation device 3 as a navigation device through the server 2 includes but is not limited to: the user provides the first navigation device 3 to the server 2 through the first communication module 111. The identification information of the navigation device 3, the serve...

Abstract

The invention provides a car following navigation method and system and a navigation system. The method comprises the steps that the navigation system obtains the first position information corresponding to a piloting first navigation device in real time and obtaining the second position information corresponding to a following second navigation device in real time at the same time; a piloting route where the first navigation device is located is determined according to at least one piece of obtained first position information; a navigation route between the piloting route and the second position information is set, so that the second navigation device conducts navigation. By means of the car following navigation method and system and the navigation system, the function of car following navigating is achieved on the second navigation device when two vehicles run at the same time.

Description

technical field [0001] The invention relates to the field of car navigation, in particular to a car-following navigation method and system, and a navigation system. Background technique [0002] Car navigation technology provides a very convenient way for people to travel. Navigation equipment uses global positioning technology to mark and guide the driver's route to the destination on the electronic map. Therefore, car navigation technology provides great convenience for people to go out and guide the way. [0003] On this basis, people have more and more demands for navigation technology. For example, when a person A and a person B make an appointment to travel from different places, in order to meet up as soon as possible, a person B needs to obtain a driving route of a person A in real time in order to keep up with a person B. If want to let a user utilize navigation to follow another user, present mode is that two people make an appointment to converge at same destin...
