BRIEF DESCRIPTION OF DRAWINGS

[0027] Figure 1 The application provides an electric vehicle charging reminding method. DETAILED DESCRIPTION

[0028] The application will be further described in detail below with reference to the drawings and the embodiments, and the purpose is to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical scheme of the application, and to help them to implement the application. In order to make the technical scheme of the application more clear, the application is explained and described by the following embodiments.

[0029] With the popularization of new energy vehicles, the charging and range problem of vehicles needs to be solved urgently. In the existing charging scheme, fixed charging devices such as charging piles and battery swap stations are generally used, but the popularization rate of these devices is not high, and they often need to be queued, which causes waste of time. In order to overcome the above problems and further alleviate the anxiety of users about the range, the application provides an electric vehicle charging reminding method, as shown in the accompanying drawings, which comprises the following steps. Figure 1 ​

[0030] Step S1, obtain the current range of the vehicle and upload to the car machine (car machine refers to the car information entertainment product installed in the car, and the car machine can realize the information communication between people and cars, cars and the outside world, and various components in the car). In this embodiment, the current range of the vehicle is 280km.

[0031] Step S2, the user sets the maximum tolerance threshold of the range in advance and uploads it to the car machine. When the range of the vehicle is greater than the maximum tolerance threshold, the user will not feel worried, and the value is set to fully follow the user's autonomous will, and the user can flexibly set it according to his own preference. In this embodiment, the maximum tolerance threshold is set to 40km.

[0032] Step S3, the user starts navigation, sets the destination, selects the navigation route and uploads it to the Internet server, and at the same time, obtains the navigation route distance and sends it to the car machine. In the existing car navigation, after the user inputs the destination, the navigation can automatically generate the corresponding navigation route and calculate the route distance, further, the existing navigation also supports automatically matching the best route or providing all routes to the user for autonomous selection according to the user's different needs (such as shortest path, shortest time, etc.).

[0033] Step S4, the car machine calculates the difference between the current range of the vehicle and the maximum tolerance threshold, and compares the difference with the navigation route distance. In this embodiment, the difference between the current range of the vehicle and the maximum tolerance threshold is 240km (280-40=240km). When the navigation route distance is greater than 240km, the user's worry will be triggered, and the user needs to be reminded to charge to avoid the generation of worry; when the navigation route distance is less than or equal to 240km, the user's worry will not be triggered, and the user can drive safely without worrying about the range.

[0034] Step S5, the Internet server obtains the fixed charging device information within the preset interval range of the navigation route based on the navigation route and sends it to the car machine. The Internet server combines big data technology and supports wireless communication with the car machine, fixed charging devices, mobile charging vehicles and the like. Among them, based on the navigation route uploaded by the car navigation, the Internet server can obtain the fixed charging device information within the preset interval range of the navigation route through big data technology, including the existence of the fixed charging device, the position coordinates of the fixed charging device and the like. In this embodiment, the preset interval range of the navigation route can be 5km, and the detour charging within 5km is a range that the user can accept. Similarly, the preset interval range fully respects the user's will and provides convenience for the user.

[0035] Step S6, the car machine integrates the comparison result of step S4 and the fixed charging device information, and judges whether to remind the user of mobile charging.

[0036] Specifically, when the difference between the current range of the vehicle and the maximum tolerance threshold is greater than or equal to the navigation route distance, that is, the user's concern is not triggered, the user is not reminded of charging.

[0037] When the difference between the current range of the vehicle and the maximum tolerance threshold is less than the navigation route distance, and there is no fixed charging device in the preset interval range of the navigation route, the user is reminded of charging.

[0038] When the difference between the current range of the vehicle and the maximum tolerance threshold is less than the navigation route distance, and there is a fixed charging device in the preset interval range of the navigation route, the car machine actively asks the user whether there is a time cost requirement, and if the user has a time cost requirement, the user is reminded of mobile charging.

[0039] In this embodiment, the mobile charging reminder can be performed by the car machine or a mobile terminal (such as a mobile phone, a tablet, etc.) connected with the car machine (communication technologies such as WiFi and Bluetooth can be used). The mobile charging reminder includes reminding the user whether to make a mobile charging vehicle reservation. After the user makes a mobile charging vehicle reservation, the car machine sends the position and the estimated arrival time on the navigation route selected by the user to the mobile charging vehicle through the Internet, and the mobile charging vehicle arrives at the position selected by the user in advance to wait. Obviously, compared with the traditional fixed charging device, the mobile charging vehicle is more flexible and can arrive at the specified position of the user in advance to wait, without queuing and saving time cost. Whether there is a fixed charging device in the interval range of the navigation route, the charging service of the mobile charging vehicle is better.

[0040] At the same time, the real-time position coordinates of the mobile charging vehicle can be synchronized to the car machine or the mobile terminal connected with the car machine through the Internet server, so as to realize the state monitoring of the mobile charging vehicle by the user.

[0041] This embodiment also constructs an electric vehicle charging reminder system according to the above-mentioned electric vehicle charging reminder method. The system includes a vehicle instrument, a car machine, a vehicle navigation, a vehicle networking device, an Internet server, a fixed charging device, a mobile charging vehicle, and a mobile terminal. The vehicle instrument, the vehicle navigation, and the mobile terminal are connected with the car machine respectively. The car machine is wirelessly connected with the Internet server through the vehicle networking device. The fixed charging device and the mobile charging vehicle are wirelessly connected with the Internet server respectively.

[0042] The vehicle instrument is used for sending the current range of the vehicle to the vehicle machine; the vehicle navigation is used for synchronizing the navigation route information of the vehicle to the vehicle machine; the vehicle network device can adopt the WiFi device, the SIM card and the like to realize the wireless communication connection between the vehicle machine and the Internet server, so as to send the navigation data of the vehicle machine to the Internet server and receive the information of the fixed charging device and the mobile charging vehicle synchronized by the Internet server; the vehicle machine is used for the preset of the system parameters (such as the maximum tolerance threshold and the like), the calculation of the difference between the current range of the vehicle and the maximum tolerance threshold and the comparison of the difference with the navigation route distance, and the mobile charging reminding judgment combined with the confidence of the fixed charging device; the Internet server combined with the big data technology is used for the storage, forwarding and analysis of data; the fixed charging device and the mobile charging vehicle are respectively used for synchronizing the state information of the fixed charging device and the mobile charging vehicle to the Internet server; and the mobile terminal is used for the mobile charging reminding.

[0043] In the embodiment, the vehicle machine comprises a man-machine interactive display screen and a vehicle machine controller, wherein the vehicle machine controller is connected with the vehicle instrument, the vehicle navigation, the mobile terminal, the vehicle network device and the man-machine interactive display screen respectively. The man-machine interactive display screen can adopt the touch type, and the mobile charging reminding is realized through the man-machine interaction; and the vehicle machine controller is used for the analysis and processing of data.

[0044] The application utilizes the maximum tolerance threshold of the range set by the user himself, participates in the range charging reminding, can make the user at ease to accept the maximum worry set by himself, at the same time, can complete the real-time seeking of the mobile charging service demand, makes the user more active and easy to control the charging reminding mode of the own vehicle. Meanwhile, the application can also expand the reservation market service function of the personal customer and the mobile charging vehicle, promotes the market development and the economic development.

[0045] The application is described above in combination with the drawings. Obviously, the specific implementation of the application is not limited by the above mode. As long as various non-essential improvements are adopted by using the method concept and the technical scheme of the application, or the above-mentioned concept and technical scheme of the application are directly applied to other occasions without improvement, all of them are within the protection scope of the application.
