Description

Technical Field

[0001] The present invention relates to the technical field of vehicle navigation, and more particularly to a navigation control method for vehicles. The present invention also relates to a corresponding navigation control system. Background Art

[0002] In recent years, with the development of technology and the improvement of living standards, more and more people choose private cars as their means of transportation. Among them, navigation technology plays an important role in the driving process of vehicles. Navigation can provide route guidance for drivers and prompt them to change lanes or decelerate when necessary, which facilitates the driving operation of drivers and greatly improves their driving experience.

[0003] Currently, vehicle occupants can use a navigation application on a mobile terminal, such as a mobile phone, or an in-vehicle navigation unit of a vehicle-mounted terminal for navigation. These two methods have their own advantages and disadvantages. Among them, the navigation application on the mobile terminal usually has the latest version of the navigation map and can obtain real-time traffic information, so it can generate an optimized navigation route. However, the screen of the mobile terminal is relatively small and not easy to fix, making it inconvenient for the driver to view the navigation route, which affects driving safety. Although the screen of the vehicle-mounted terminal is large and convenient for the driver to view, the built-in navigation map of the in-vehicle navigation unit of the vehicle-mounted terminal is usually offline and cannot display real-time traffic information, resulting in the generated navigation route may not meet the expectations of vehicle occupants.

[0004] To make full use of the advantages of the above two navigation methods, in the prior art, the screen content of the mobile terminal can be projected onto the vehicle-mounted screen of the vehicle-mounted terminal through screen mirroring technology. This has problems with the adaptation between the mobile terminal and the vehicle-mounted terminal and also requires the support of third-party screen mirroring software, such as Carplay or Hicar, when necessary. In addition, it is also possible to achieve interconnection and communication through the same navigation application on the mobile terminal and the vehicle-mounted terminal to transmit the navigation information of the mobile terminal to the vehicle-mounted terminal in real time. However, this places high requirements on both the mobile terminal and the vehicle-mounted terminal in terms of applications. When the navigation applications on the mobile terminal and the vehicle-mounted terminal are inconsistent or have different versions, the synchronization of navigation information cannot be achieved. Summary of the Invention

[0005] Therefore, the object of the present invention is to provide an improved navigation control method for vehicles, through which the synchronization of navigation information between the mobile terminal and the vehicle-mounted terminal can be easily achieved without requiring the adaptation of the mobile terminal and the vehicle-mounted terminal, especially the navigation applications, and the transmission efficiency of navigation information is improved, thereby improving the driving experience of the driver and realizing the safe and efficient driving of the vehicle. In addition, the object of the present invention is also to provide a corresponding navigation control system.

[0006] According to a first aspect of the present invention, there is provided a navigation control method for a vehicle, wherein the navigation control method at least includes the following steps:

[0007] S1: Establish a communication connection between the mobile terminal of the occupant and the in-vehicle terminal of the vehicle;

[0008] S2: Send first navigation information to the in-vehicle navigation unit of the in-vehicle terminal through the navigation application of the mobile terminal, where the first navigation information at least includes a starting point, an ending point, and at least one waypoint;

[0009] S3: Update the second navigation information of the in-vehicle navigation unit according to the first navigation information, so that the in-vehicle navigation unit generates a navigation route starting from the starting point, passing through the at least one waypoint, and ending at the ending point. Among them, when comparing the first navigation information and the second navigation information, when the comparison result is inconsistent, modify the second navigation information according to the first navigation information.

[0010] Compared with the prior art, in the navigation control method for a vehicle according to the present invention, when a communication connection is established between the mobile terminal and the in-vehicle terminal, the first navigation information is sent to the in-vehicle navigation unit of the in-vehicle terminal through the navigation application of the mobile terminal. The first navigation information at least includes a starting point, an ending point, and at least one waypoint. The in-vehicle navigation unit updates its second navigation information according to the first navigation information to generate a navigation route corresponding to the first navigation information on the in-vehicle navigation unit of the in-vehicle terminal. Among them, when the comparison result between the first navigation information and the second navigation information is inconsistent, modify the second navigation information according to the first navigation information. Thus, only the navigation information including the starting point, the ending point, and at least one waypoint needs to be transmitted between the mobile terminal and the in-vehicle terminal, and the navigation route set by the vehicle occupant on the mobile terminal can be easily synchronized and displayed through the in-vehicle terminal. This does not require adaptation between the navigation applications of the mobile terminal and the in-vehicle terminal and greatly reduces the amount of transmitted data. Therefore, the advantages of the mobile terminal and the in-vehicle terminal can be fully utilized, which significantly improves the driving experience of the driver and can achieve safe and efficient driving of the vehicle.

[0011] Exemplarily, in step S3, set the same number of waypoints in the second navigation information as the number of waypoints in the first navigation information, where the navigation distances of the corresponding waypoints in the first navigation information and the second navigation information relative to the starting point are the same.

[0012] Exemplarily, in step S2, the waypoint is set in a section where there is an alternative navigation route, and there are particularly traffic impact points in the alternative navigation route, and the traffic impact points relate to road construction and / or congestion and / or traffic accidents.

[0013] Exemplarily, in step S3, when the in-vehicle navigation unit itself does not have navigation information set, the second navigation information is directly set according to the first navigation information.

[0014] Exemplarily, the waypoint is a geographical coordinate and / or a landmark building and / or a road name; and / or, the mobile terminal and the in-vehicle terminal are communicatively connected based on Bluetooth technology.

[0015] Exemplarily, during the driving of the vehicle, the navigation application of the mobile terminal refreshes the first navigation information at a specific frequency to optimize the navigation route. Wherein, when the first navigation information changes, steps S2 and S3 are executed.

[0016] Exemplarily, the navigation application of the mobile terminal can refresh and send the first navigation information in the screen-off state or the background state; and / or, the navigation application refreshes the first navigation information according to the preset requirements of the occupant to optimize the navigation route, and the preset requirements are selected from the following group: shortest distance, least time, fewest traffic lights, no highway, avoiding restricted sections.

[0017] Exemplarily, in step S3, when the first navigation information and the second navigation information are inconsistent, a modification request is sent to the occupant of the vehicle, and the second navigation information is modified according to the first navigation information after obtaining a confirmation instruction.

[0018] According to a second aspect of the present invention, there is provided a navigation control system for a vehicle, wherein the navigation control system is configured to be adapted to implement the navigation control method according to the present invention, and wherein the navigation control system at least includes:

[0019] - A mobile terminal having a navigation application configured to generate first navigation information, the first navigation information at least including a starting point, an ending point, and at least one waypoint; and

[0020] - An in-vehicle terminal configured to be communicatively connected to the mobile terminal and having an in-vehicle navigation unit to update the second navigation information of the in-vehicle navigation unit according to the first navigation information and generate a corresponding navigation route.

[0021] Exemplarily, the mobile terminal is a smart phone, a smart watch or a tablet computer; and / or, the vehicle-mounted navigation unit of the vehicle-mounted terminal has a positioning receiver, a map database, vehicle-mounted navigation software and an interaction interface, wherein the vehicle-mounted navigation software generates the navigation route on the map database according to the second navigation information, and the navigation route is displayed on the interaction interface.

[0022] Hereinafter, the present invention will be described in more detail by referring to the accompanying drawings, and the principles, features and advantages of the present invention can be better understood. The accompanying drawings include:

[0023] Figure 1 FIG. shows a schematic flowchart of a navigation control method for a vehicle according to an exemplary embodiment of the present invention;

[0026] In order to make the technical problems to be solved, technical solutions and beneficial technical effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and a plurality of exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the protection scope of the present invention.

[0027] This specification provides method operation steps as described in the embodiments or flowcharts, but may include more or fewer operation steps based on routine or non-creative labor. The step sequences listed in the embodiments are only one way among the execution sequences of numerous steps, and do not represent the only execution sequence.

[0028] Figure 1 FIG. shows a schematic flowchart of a navigation control method for a vehicle according to an exemplary embodiment of the present invention. Figure 2 FIG. shows a comparison diagram of navigation information of a navigation control method for a vehicle according to an exemplary embodiment of the present invention.

[0029] As Figure 1 shown, the navigation control method for a vehicle according to the present invention at least includes the following steps:

[0030] S1: Establish a communication connection between the mobile terminal of the occupant and the in-vehicle terminal of the vehicle to enable data transmission between the two. The mobile terminal is, for example, a smart phone. After the occupant gets in the vehicle, when connection authorization has been obtained, the mobile terminal and the in-vehicle terminal are automatically communicatively connected, especially based on Bluetooth technology. The occupants of the vehicle can be all the people inside the vehicle, including the driver and passengers, so that each occupant can perform navigation control according to their own needs.

[0031] S2: Send the first navigation information to the in-vehicle navigation unit of the in-vehicle terminal through the navigation application of the mobile terminal. The first navigation information includes at least a starting point, an ending point, and at least one waypoint. This greatly reduces the amount of data transmitted and improves the transmission efficiency. The occupant can input the desired starting point and ending point on the navigation application, and the navigation application automatically generates the corresponding navigation route. The waypoint is located on the navigation route. The navigation application is, for example, Baidu Map, Amap, Google Map, etc. Of course, other navigation applications that are considered meaningful by those skilled in the art can also be considered.

[0032] S3: The in-vehicle terminal updates the second navigation information of the in-vehicle navigation unit according to the first navigation information from the mobile terminal, so that the in-vehicle navigation unit generates a navigation route starting from the starting point, passing through the at least one waypoint, and ending at the ending point. The in-vehicle navigation unit compares the first navigation information with the second navigation information. When the comparison result shows inconsistency, the second navigation information is modified according to the first navigation information so that the second navigation information has exactly the same starting point, ending point, and waypoint as the first navigation information.

[0033] As Figure 2As shown, in step S2, a first navigation route L1 is generated based on the first navigation information sent by the navigation application of the mobile terminal. The first navigation route is drawn as a solid line and includes a starting point S, an ending point T, and a plurality of waypoints P1, P2, P3... Pn. And a second navigation route L2 is generated based on the second navigation information of the in-vehicle navigation unit itself. The second navigation route is drawn as a dashed line and includes a starting point S, an ending point T, and the same number of a plurality of waypoints P1', P2', P3'... Pn'. Among them, in order to clearly display the route comparison result, the first navigation route L1 and the second navigation route L2 are staggered from each other. In step S3, the first navigation information and the second navigation information are compared. When the first navigation route L1 and the second navigation route L2 do not coincide, that is, any of the waypoints P1, P2, P3... Pn in the first navigation information is different from the corresponding waypoints P1', P2', P3'... Pn' in the second navigation information, the second navigation information is modified so that the second navigation route L2 generated according to the second navigation information has exactly the same starting point, ending point, and waypoints as the first navigation route L1. It can be considered here that the comparison result of the first navigation information and the second navigation information can be presented and recorded in the form of a table, as shown in the following Table 1:

[0034] First navigation information Second navigation information Comparison results Starting point S Starting point S same Waypoint P1 Passage point P1' same Waypoint P2 Passage point P2' different Waypoint P3 Passage point P3' different … … … Passing point Pn Passing point Pn' same End point T End point T same

[0035] Table 1

[0036] Here, only the waypoints with different comparison results can be focused on and the second navigation information can be modified according to the first navigation information, so that the in-vehicle navigation unit generates a navigation route starting from the starting point S, passing through at least one of the waypoints P1, P2, P3... Pn, and ending at the ending point T corresponding to the first navigation information.

[0037] Thereby, it is possible to easily ensure that the navigation route displayed on the in-vehicle terminal is the same as that of the navigation application of the mobile terminal and meets the requirements of the occupants. This can make full use of the advantages of the mobile terminal in obtaining real-time traffic information and the advantages of the in-vehicle terminal in facilitating the driver to view the navigation route, without the need for the navigation software of the in-vehicle terminal and the mobile terminal to be adapted to each other or have the same version and without the support of a third-party software.

[0038] Exemplarily, the first navigation information of the mobile terminal particularly includes a plurality of waypoints through which the navigation route desired by the occupant can be mapped. The number of the waypoints is related to, for example, the navigation distance and / or the complexity of the road conditions. The longer the navigation distance and the more complex the road conditions are, the more waypoints the first navigation information includes. Correspondingly, in step S3, the same number of waypoints as that in the first navigation information are set in the second navigation information of the in-vehicle navigation unit. Among them, the navigation distances of the corresponding waypoints in the first navigation information and the second navigation information relative to the starting point are the same. For example, the navigation distances of the respective first waypoints in the first navigation information and the second navigation information relative to the starting point are both 2 kilometers, and the navigation distances of the respective second waypoints relative to the starting point are both 4 kilometers. Thus, the respective waypoints of the two can be clearly corresponded and it can be determined whether the corresponding waypoints are the same.

[0039] Exemplarily, in step S2, the waypoints in the first navigation information are set in the sections where there are alternative navigation routes. The vehicle can also reach the destination via the alternative navigation routes. The waypoints set in these sections can clearly identify the navigation route desired by the occupant, and there is no need to set waypoints for the sections where there are no alternative navigation routes. This can reduce the number of waypoints and avoid setting meaningless waypoints. As Figure 2 shown, the waypoints P1…Pn in the first navigation information are set in the following sections of the first navigation route L1, and this section does not coincide with the second navigation route L2, that is, this section has an alternative navigation route to the second navigation route L2, and there is no need to set waypoints for the section where the first navigation route L1 and the second navigation route L2 coincide with each other. Particularly, there is a traffic impact point I in the alternative navigation route, and the traffic impact point I can be road construction and / or congestion and / or traffic accident, so that the vehicle needs to spend more time to pass through the alternative navigation route. In this case, compared with the alternative navigation route, the first navigation route L1 calibrated by the first navigation information can bypass the traffic impact point I, thereby enabling the vehicle to effectively avoid the undesired road conditions and improve the traffic efficiency. Here, the waypoint can be, for example, a geographical coordinate, and the geographical coordinate can be detected by a positioning device, such as a GPS or a Beidou locator. However, it is also possible that the waypoint is a landmark building and / or a road name, etc.

[0040] Exemplarily, in step S3, when the in-vehicle navigation unit of the in-vehicle terminal itself does not set navigation information, the in-vehicle navigation unit directly sets the second navigation information according to the received first navigation information, which can avoid the occupant from laboriously repeating the input.

[0041] Exemplarily, during the driving of a vehicle, the navigation application of the mobile terminal refreshes the first navigation information, especially the waypoints, at a specific frequency, for example, every 5 minutes, to optimize the navigation route in real time or to find a better route. Among them, the navigation application of the mobile terminal can refresh the first navigation information according to the preset requirements of the occupant, and the preset requirements can be selected from the following group: shortest distance, least time, few traffic lights, no highway, bypass restricted sections. Of course, other occupant requirements considered meaningful by those skilled in the art can also be considered. Thus, the navigation route can be optimized in a timely manner according to the real-time traffic information, thereby enhancing the riding experience of the occupant. Here, when the first navigation information of the mobile terminal changes, steps S2 and S3 are executed to send the first navigation information to the vehicle terminal and accordingly update the second navigation information of the in-vehicle navigation unit. This avoids the occupant from repeatedly setting the navigation information of the in-vehicle navigation unit. In particular, the navigation application of the mobile terminal can refresh and send the first navigation information in the screen-off state or the background state, which can effectively reduce the power consumption of the mobile terminal.

[0042] Exemplarily, in step S3, when the first navigation information from the mobile terminal is inconsistent with the second navigation information of the in-vehicle navigation unit, the vehicle terminal sends a modification request to the occupant of the vehicle, for example, through an interaction interface or a voice interaction device. After obtaining the confirmation instruction of the member, the in-vehicle navigation unit modifies the second navigation information according to the first navigation information. However, it is also possible that when the first navigation information and the second navigation information are inconsistent, the in-vehicle navigation unit directly automatically modifies the second navigation information according to the first navigation information.

[0043] Figure 2 Fig. shows a schematic connection block diagram of a navigation control system 100 for a vehicle according to an exemplary embodiment of the present invention. Here, the navigation control system 100 can implement the navigation control method according to the present invention.

[0044] As Figure 2 shown, the navigation control system 100 includes a mobile terminal 10, which has a navigation application, such as Baidu Map, Gaode Map, Google Map, etc. The navigation application is configured to generate first navigation information according to real-time traffic information. The first navigation information includes at least a starting point, an ending point, and at least one waypoint. Based on the first navigation information, a navigation route that meets the needs of the occupant can be realized. Here, the mobile terminal 10 is particularly configured as a smart phone. However, it is also possible that the mobile terminal 10 is configured as a smart watch, a tablet computer, or other electronic devices considered meaningful by those skilled in the art.

[0045] As Figure 2As shown, the navigation control system 100 includes a vehicle-mounted terminal 20, which is configured to communicate with a mobile terminal 10, for example, based on Bluetooth technology and has an in-vehicle navigation unit. The in-vehicle navigation unit can receive first navigation information from the mobile terminal 10, update its own second navigation information according to the first navigation information, and generate a corresponding navigation route based on the second navigation information. The navigation route is exactly the same as the navigation route set by the occupant on the mobile terminal 10. Here, the in-vehicle navigation unit 20, for example, has a positioning receiver, a map database, in-vehicle navigation software, and an interaction interface. Among them, the positioning receiver is configured to detect the geographical coordinates of the vehicle, the in-vehicle navigation software is configured to generate a corresponding navigation route on the map database according to the second navigation information, and the navigation route is displayed on the interaction interface, which is, for example, configured as a touch display screen. In particular, the vehicle occupant can also input personalized instructions through the interaction interface.

[0046] The foregoing explanations of the embodiments only describe the present invention within the framework of the examples. Of course, as long as it is technically meaningful, the various features of the embodiments can be freely combined with each other without departing from the framework of the present invention.

[0047] For those skilled in the art, other advantages and alternative embodiments of the present invention are obvious. Therefore, the present invention in its broader sense is not limited to the specific details, representative structures, and exemplary embodiments shown and described. On the contrary, those skilled in the art can make various modifications and substitutions without departing from the basic spirit and scope of the present invention.
