Navigation route planning method for reducing driving operation difficulty

Abstract

The present invention discloses a navigation route planning method that reduces the difficulty of driving operations. The main design concept of the present invention is that after entering a preset navigation mode, information about the starting point and the end point is obtained, and then several driving item selection interfaces are presented to the user, wherein the driving items are predetermined road conditions that increase the difficulty of driving operations, and each driving item has a gear position for the user to select, and each gear position has a corresponding weight score. Based on the driving item selection results input by the user and the number of each road condition item included in the path from the starting point to the end point, at least one navigation route is recommended to the user. The present invention can use the gear options independently selected by the driver to specifically avoid the current driver's weaknesses in the navigation route as much as possible, thereby adjusting the length of the detour according to personalized needs, and further balancing the difficulty of driving operations with travel time, thereby improving the safety and reliability of the user's travel.

Description

Technical Field

[0001] The present invention relates to the technical field of vehicle navigation, and in particular to a navigation route planning method for reducing the difficulty of driving operation. Background Art

[0002] Navigation technology currently used in cars is relatively mature. Generally speaking, after selecting a departure and destination, the navigation system will provide drivers with several route options from the starting point to the destination, including, but not limited to, the following navigation planning dimensions: shortest distance mode, minimum travel time mode, fuel-saving mode, and congestion avoidance mode.

[0003] The above navigation mode and its matching algorithm can meet the needs of most drivers. However, in actual driving scenarios, in addition to the above-mentioned emphasis on driving speed and energy saving and efficiency, drivers also have another type of personalized driving demand, that is, they can sacrifice speed and energy consumption in exchange for stable and safe driving.

[0004] Such demands mostly arise from drivers who lack driving experience, and the existing navigation planning dimensions cannot adapt to such drivers. Therefore, the industry urgently needs a navigation planning dimension with a "stable driving mode" (the so-called stable driving mode in this invention refers to a path recommendation mode that is safe, stable, and easy to drive and meets the personalized needs of a certain type of driver). Summary of the Invention

[0005] In view of the above, the present invention aims to provide a navigation route planning method that reduces the difficulty of driving operations, so as to solve the technical problems mentioned above.

[0006] The technical solution adopted in the present invention is as follows:

[0007] The present invention provides a navigation route planning method for reducing the difficulty of driving operation, which includes:

[0008] After entering the preset navigation mode, obtain the starting point and end point information;

[0009] Presenting a plurality of driving item selection interfaces to the user, wherein the driving items are predetermined road conditions that increase the difficulty of the driving operation, and each driving item has a gear position for the user to select, and each gear position has a corresponding weight score;

[0010] At least one navigation route is recommended to the user based on the driving item selection result input by the user and in combination with the number of each road condition item included in the path from the starting point to the end point.

[0011] In at least one possible implementation, recommending at least one navigation route to the user includes:

[0012] Calculate the number of each road condition item included in each route from the starting point to the end point;

[0013] Calculate the product of the number of road condition items and the weight score of the gear selected by the user for each route as the total route score of each route;

[0014] The routes are sorted from low to high according to their total scores, and the route with the lowest total score is taken as the first recommended route.

[0015] In at least one possible implementation, recommending at least one navigation route to the user further includes: if there is a highest weight score in the gear selection results input by the user, searching for a route with the least number of road condition items corresponding to the highest weight score as the second recommended route.

[0016] In at least one possible implementation, recommending at least one navigation route to the user further includes:

[0017] If there are multiple highest weighted scores in the selection results input by the user, the route with the least number of single road condition items with the highest weighted scores will be used as the second recommended route;

[0018] Then, the route with the smallest average number of all road condition items involving the highest weight score is used as the third recommended route.

[0019] In at least one possible implementation, the gear selection interface also includes a time option with multiple gears.

[0020] In at least one possible implementation, the duration corresponding to each gear in the time options is set according to a multiple of the time taken by a navigation path that takes the least time between a starting point and an end point.

[0021] In at least one possible implementation, the duration of the final recommended navigation route is less than or equal to the duration corresponding to the time option gear selected by the user.

[0022] In at least one possible implementation, the time taken for the navigation route includes: the sum of the vehicle driving time and the walking time from the starting point to the end point.

[0023] Compared to the prior art, the present invention's key design concept lies in: after entering a preset navigation mode, it obtains information about the starting and ending points, then presents the user with several driving item selection screens. These screens are defined as road conditions that increase the difficulty of driving, and each driving item has a selectable gear position, each assigned a different weighted score. Based on the user-entered driving item selection results and the number of each road condition item included in the path from the starting point to the end point, the present invention recommends at least one navigation route to the user. By leveraging the driver's independently selected gear position, the present invention can specifically minimize the driver's weaknesses in the navigation route, thereby adjusting the length of the detour based on individual needs, thereby balancing driving difficulty with travel time, and thus improving the safety and reliability of the user's travel. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described below with reference to the accompanying drawings, in which:

[0025] Figure 1 A flowchart of a navigation route planning method for reducing the difficulty of driving operations provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0026] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0027] The present invention proposes an embodiment of a navigation route planning method for reducing the difficulty of driving operation. Specifically, Figure 1 shown, including:

[0028] Step S1: After entering the preset navigation mode (the preset navigation mode mentioned here may be the "stable driving mode" defined above, but it is understandable that in actual applications, it is not limited to this name), obtain the starting point and end point information;

[0029] Step S2: Displaying a plurality of driving event selection interfaces to the user, wherein the driving events are predetermined road conditions that increase driving difficulty, such as sharp turns, U-turns, dense traffic, narrow roads, steep slopes, multiple forks, multiple large vehicles, and parking difficulties, which are not user-friendly for inexperienced drivers. The interface includes a gear for user selection corresponding to each driving event, with each gear assigned a different weight.

[0030] Taking the "Narrow Road Section" item as an example, it can include three gears: no need to avoid, avoid as much as possible, and avoid completely. The "no need to avoid" gear is preset with the lowest weight score of the road condition item (such as C points) in the background, the "completely avoid" gear is preset with the highest weight score of the road condition item (such as S points) in the background, and the "avoid as much as possible" gear is corresponding to a score in the middle (such as B points). It can be understood that the above gear settings and weight score settings are all examples, and the present invention does not limit the number of gears and specific weight score settings for each item.

[0031] It can be added here that in some other embodiments of the present invention, the gear selection interface also includes time options with multiple gears. Since the goal of the present invention is to provide users with a personalized navigation route that is stable, safe, and reduces operational difficulties, concessions can be made on the journey time. However, in order to further meet the specific needs of users, time constraint items can be provided, that is, users can be allowed to balance safe driving and driving time. Therefore, the time option can be designed as a multiple of the time taken by the navigation path with the shortest time between the starting point and the end point, such as the time option for the lowest gear is 1.1 times, the time option for the highest gear is 2 times, and there are several intermediate time gears between the lowest and highest.

[0032] Step S3: recommend at least one navigation route to the user based on the driving item selection result input by the user and the number of each road condition item included in the path from the starting point to the end point.

[0033] For this part, the following can be explained:

[0034] Calculate the number of each road condition item included in each route from the starting point to the end point;

[0035] Calculate the total score of each route by multiplying the number of road condition items by the weight of the gear selected by the user.

[0036] For example, the total score of route a = 1 sharp turn × B points + 0 U-turns × S points + 1 crowded area × C points + 1 narrow section × C points + 0 steep slopes × C points + 2 forks in the road × C points + 1 large vehicle × B point + 1 parking difficulty × S points.

[0037] Continuing from the previous article, the routes are sorted from low to high according to their total scores, and the route with the lowest total score is used as the first recommended route (if multiple routes have the same lowest score, the routes involved will be listed as the "first recommended route").

[0038] Further optimization can be done. If there is a highest weighted score in the selection results input by the user, then the route with the least number of road condition items corresponding to the highest weighted score is found as the second recommended route (if multiple routes all have the least number of such items, then based on the aforementioned total score sorting, the route with the relatively lowest score will be listed as the second recommended route).

[0039] For example, in the case of sharp turns, U-turns, dense traffic, narrow roads, steep slopes, multiple forks, many large vehicles, and difficult parking, only narrow roads are selected as "completely avoided" (with the highest weight score S). Therefore, the route between the starting point and the end point with the least narrow roads and the lowest total score is listed as the second recommended route.

[0040] What can also be optimized is that if there are multiple highest weight scores in the gear selection results input by the user, the route with the least number of single road condition items will be included in the second recommended route first, and then the route with the smallest average number of all road condition items involving the highest weight scores will be included as the third recommended route.

[0041] For example, for sharp turns, U-turns, dense traffic, narrow sections, steep slopes, multiple forks, many large vehicles, and difficult parking, the narrow sections and steep slopes in this road condition item are both selected as "completely avoid". Therefore, the route with the least narrow sections and the relatively lowest total score, and the route with the least steep slopes and the relatively lowest total score are both listed as the second recommended routes; then, the route with (number of narrow sections + number of steep slopes) / 2 and the relatively lowest average score is listed as the third recommended route.

[0042] Finally, two additional points can be made:

[0043] First, in conjunction with the aforementioned embodiment where a time option is selected as one of the driving conditions, the final recommended navigation route should have a duration less than or equal to the duration corresponding to the time option selected by the user. This means that when calculating the various recommended routes, the duration of the time options is considered as a concurrent time constraint. For example, when selecting the first recommended route, the route with the lowest total score and a time that meets the time constraint is considered.

[0044] Second, the navigation route duration includes the sum of the driving time and walking time from the starting point to the end point. This concept is particularly applicable to parking navigation and when the selected item includes "Difficult Parking". For example, when the gear with the "Difficult Parking" rating is not the lowest-scoring gear (not C), the vehicle's destination in the navigation route is determined to be a suitable location that is relatively close to the input end point and relatively easy to park. The total route duration is: the time to reach the parking location + the walking time to the end point.

[0045] In summary, the main design concept of the present invention is to obtain starting and ending point information after entering a preset navigation mode, and then present the user with several driving item selection interfaces, wherein the driving items are predetermined road conditions that increase the difficulty of the driving operation, and each driving item has a gear position for the user to select, and each gear position has a corresponding weight score. Based on the driving item selection results input by the user and the number of each road condition item included in the path from the starting point to the end point, at least one navigation route is recommended to the user. By using the gear position options independently selected by the driver, the present invention can specifically avoid the driver's weaknesses in the navigation route, thereby adjusting the length of the detour according to individual needs, and thus balancing driving difficulty and travel time, thereby improving the safety and reliability of the user's travel.

[0046] If the expressions expressing directions are mentioned in the embodiments of the present invention, they are relative concepts based on the embodiments. In addition, "at least one" refers to one or more, and "more" refers to two or more. "And / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B can represent the existence of A alone, the existence of A and B at the same time, and the existence of B alone. Among them, A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" and similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b and c can represent: a, b, c, a and b, a and c, b and c or a, b and c, where a, b, c can be single or multiple.

[0047] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings, but the above is only a preferred embodiment of the present invention. It should be noted that the technical features involved in the above embodiments and their preferred modes can be reasonably combined and matched into a variety of equivalent schemes by those skilled in the art without departing from or changing the design ideas and technical effects of the present invention; therefore, the scope of implementation of the present invention is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present invention.
