Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a method, apparatus, electronic device, and vehicle for displaying map bar charts. Background Technology

[0002] A map bar chart uses a single bar to display traffic congestion along a route, with different colors indicating different levels of congestion. This allows users to quickly obtain navigation information and provides an intelligent and personalized navigation experience, while also enabling them to understand road conditions more intuitively.

[0003] In related technologies, existing map bar graphs often obscure the actual vehicle positions by having vehicle icons cover the graph, preventing users from obtaining accurate road conditions and leading to incorrect guidance. Summary of the Invention

Based on the correction display ratio of the target sub-segment and the initial display ratio of the target sub-segment, calculate the adjustment ratio of the target sub-segment. Based on the relationship between the adjustment ratio of the target sub-segment and the sum of the initial display ratios of all non-target sub-segments, determine whether the initial map bar chart meets the second level of correction display conditions.

[0020] If the initial map bar chart meets the second-level correction display conditions, the correction display ratio of non-target sub-segments is calculated based on the correction display ratio of the target sub-segment;

[0031] Determine the relationship between the initial display ratio and the average clipping ratio of each non-target sub-segment;

[0032] When the initial display ratio of all non-target sub-segments is greater than the average clipping ratio, the corrected display ratio of each non-target sub-segment is obtained based on the initial display ratio and the average clipping ratio of the non-target sub-segments.

[0033] If the initial display ratio of a non-target sub-segment is less than or equal to the average clipping ratio, the weight clipping ratio of the non-target sub-segment is calculated based on the preset weight ratio of the non-target sub-segment. Based on the initial display ratio and weight clipping ratio of the non-target sub-segment, the corrected display ratio of each non-target sub-segment is obtained.

[0076] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0077] In existing technologies that utilize map bar charts for display, when a certain road segment represents a relatively small percentage of the total road segment, the car logo, due to its different display ratio compared to other road segments in the map bar chart, will obscure the image of that road segment in the map bar chart. This results in the map bar chart failing to accurately represent the actual road conditions.

[0078] As an example, if road segment A accounts for 5% of the total road segments, then the corresponding display length in the map bar chart will be 5%. When the vehicle reaches the middle of road segment A, there is actually still half of road segment A remaining. However, due to the vehicle icon obscuring road segment A in the map bar chart, users may think that road segment A has been completed, thus creating a false impression and preventing users from obtaining the true road conditions.

[0079] Based on this, the inventor proposed the inventive concept of this application: to increase the visibility range of the current road segment in the map bar chart and adjust the visibility range of non-current segments accordingly, thereby helping users to obtain road condition information of the current road segment more intuitively.

[0080] This invention provides a method for displaying map bar charts, see [link to relevant documentation]. Figure 1 , Figure 1 This illustration shows a flowchart of a map bar chart display method according to an embodiment of this application, applied to a vehicle's infotainment system. The method includes:

[0081] S101: Generate an initial map bar chart based on the traffic status of the target road segment.

[0082] In this implementation, the target road segment refers to the driving route pre-set by the user according to their itinerary. The user can input the corresponding starting point and ending point of the trip on the vehicle navigation interface to generate the target road segment. Traffic status refers to the congestion level of the current road segment, which can be set according to the user's needs. For example, traffic status can be free-flowing, slow-moving, or congested. The target road segment can be divided into multiple sub-segments, and the traffic status of each sub-segment is different from that of its adjacent sub-segments. The steps for generating the initial map bar chart based on the traffic status of the target road segment can be as follows:

[0083] S101-1: Obtain the length of each sub-segment and the total length of the target segment.

[0084] In this embodiment, firstly, each sub-segment can be numbered in order from the starting point to the end point, either alphabetically or numerically. Then, the length of each sub-segment and the total length of the target segment are obtained.

[0085] S101-2: Calculate the initial display ratio of each sub-segment based on the ratio of the length of each sub-segment to the total length of the target segment.

[0086] In this implementation, the length of each sub-segment in the map bar chart is calculated based on the ratio of its length to the total length of the target road segment. Let the length of the map bar chart be A. If the ratio of a sub-segment's length to the total length of the target road segment is 0.2, then the length of that sub-segment in the map bar chart is 20% of the total length of the map bar chart. The initial display ratio of a sub-segment can be understood as the ratio of its displayed length to the initial displayed length of the map bar chart. Therefore, the initial display ratio of a sub-segment can be dynamically adjusted based on changes in the initial displayed length of the map bar chart.

[0087] S101-3: Determine the display color of each sub-segment based on the traffic status of each sub-segment.

[0088] In this embodiment, different display colors are used to represent different traffic conditions. For example, green represents a smooth flow, yellow represents a slow flow, and red represents a congested flow.

[0089] S101-4: Generate the initial display image for each sub-segment based on its initial display ratio and display color;

[0090] S101-5: Based on the corresponding road segment number of each sub-road segment, stitch together the initial display images of each sub-road segment to generate an initial map bar chart.

[0091] In the embodiments S101-4 to S101-5, after obtaining the initial image display length and corresponding display color of each sub-segment, the corresponding display image can be generated. Then, according to the ascending order of the corresponding segment numbers, the display images are sequentially stitched together to obtain the image shown below. Figure 2 The initial map bar chart shown can be understood as a map bar chart drawn according to the actual scale of the road segment, but it cannot improve the visibility range of the current road segment. Therefore, it needs to be corrected while meeting the display conditions.

[0092] S102: Generate corrected display images of the target sub-segment and non-target sub-segment.

[0093] In this embodiment, the target sub-segment refers to the sub-segment where the vehicle is currently located, while the non-target sub-segment refers to a sub-segment with a segment number greater than the target sub-segment that the vehicle has not yet completed its journey. Improving the visibility of the target sub-segment is essentially a process of correcting the initial display images of both the sub-segment and the non-target sub-segment. The specific steps can be as follows:

[0094] S102-1: Based on the initial display ratio of the target sub-segment, determine whether the initial map bar chart meets the first-level correction display conditions.

[0095] In this implementation, the first level of display correction is determined when the user cannot see the current road conditions clearly or has difficulty seeing them. In this case, we need to zoom in on the current display to allow the user to better view the current road conditions and improve the user experience. The specific steps are as follows:

[0096] S102-1-1: Determine the relationship between the initial display ratio and the preset threshold;

[0097] S102-1-2: If the initial display ratio is less than the preset threshold, determine that the initial map bar chart meets the first level of correction display conditions;

[0098] In the implementations of S102-1-1 to S102-1-2, firstly, the initial display scale needs to be compared with a preset threshold display scale, because only when the initial display scale is less than a threshold will the user be unable to see clearly. If the initial display scale is greater than or equal to the preset threshold, it indicates that the initial image corresponding to the current target sub-segment meets the user's needs and no correction is required; therefore, the initial map bar chart is directly displayed as the target map bar chart. If the initial display scale is greater than or equal to the preset threshold, it is determined that the initial map bar chart does not meet the first-level correction display conditions, and the initial map bar chart is displayed as the target map bar chart.

[0099] S102-2: If the initial map bar chart meets the first level of correction display conditions, calculate the correction display ratio of the target sub-segment, calculate the adjustment ratio of the target sub-segment based on the correction display ratio of the target sub-segment and the initial display ratio of the target sub-segment, and determine whether the initial map bar chart meets the second level of correction display conditions based on the relationship between the adjustment ratio of the target sub-segment and the sum of the initial display ratios of all non-target sub-segments.

[0100] In this embodiment, if the initial map bar chart meets the first-level correction display conditions, it is necessary to determine whether the display ratio that can be cropped from the non-target sub-road segment is greater than the increased display ratio of the target sub-road segment. The corrected display ratio of the target sub-road segment can be calculated in the following way: the corrected display ratio of the target sub-road segment consists of three parts. The first part is the initial display ratio of the target sub-road segment; the second part is the ratio by which the small car icon covers the initial display portion of the target sub-road segment, i.e., the car icon occupancy compensation display ratio; and the third part is the general compensation display ratio. The general compensation display ratio is added because simply increasing the car icon occupancy compensation display ratio cannot solve this problem well. Therefore, a certain coefficient needs to be added to this road segment to magnify it so that users can see the current road better and more intuitively. The general compensation display ratio can be set differently according to different vehicle models, and this application does not limit this. If users can see the current road better and more intuitively without increasing the general compensation display ratio, the compensation display ratio is set to 0, i.e., only the car icon occupancy compensation display ratio is increased. As an example, if the corrected display ratio of the target sub-segment is n, the initial display ratio of the target sub-segment is x, the vehicle logo occupancy compensation display ratio is y, and the general compensation display ratio is z, then the corrected display ratio of the target sub-segment n = the initial display ratio x + the vehicle logo occupancy compensation display ratio y + the general compensation display ratio z.

[0101] After obtaining the corrected display ratio of the target sub-segment, it is equivalent to adding two parts to the original display ratio: the vehicle logo occupancy compensation display ratio and the general compensation display ratio. Therefore, it is necessary to determine whether the non-target sub-segments can reduce their corresponding display ratio. Only when the increase in the corrected display ratio of the target sub-segment compared to the initial display ratio of the target sub-segment, i.e., the adjustment ratio, is less than the sum of the initial display ratios of all non-target sub-segments, can it be said that the non-target sub-segments can reduce their corresponding display ratio, i.e., the initial map bar chart meets the second-level corrected display conditions.

[0102] S102-3: If the initial map bar chart meets the second-level correction display conditions, calculate the correction display ratio of non-target sub-segments based on the correction display ratio of the target sub-segments.

[0103] In this embodiment, if the initial map bar chart meets the second-level correction display conditions, it is necessary to calculate the correction display ratio of non-target sub-road segments. The specific steps are as follows:

[0104] S102-3-1: Obtain the general compensation display ratio and the vehicle logo occupancy compensation display ratio. Based on the general compensation display ratio, the vehicle logo occupancy compensation display ratio, and the initial display ratio, determine the corrected display ratio for the target sub-segment.

[0105] S102-3-2: Obtain the total number of non-target sub-segments, and determine the average clipping ratio of non-target sub-segments based on the general compensation display ratio, the vehicle logo occupancy compensation display ratio, and the total number of non-target sub-segments.

[0106] In the implementations of S102-3-1 to S102-3-2, the corrected display ratio of the target sub-segment is first calculated, the total number of non-target sub-segments is the sum of the number of target sub-segments, and then the average clipping ratio of the non-target sub-segments is calculated according to the following formula.

[0107] Average clipping ratio j for non-target sub-segments = (General compensation display ratio z + Vehicle logo occupancy compensation display ratio y) / Total number of non-target sub-segments m

[0108] S102-3-3: Determine the corrected display ratio for each non-target sub-segment based on the average clipping ratio and the initial display ratio for each non-target sub-segment.

[0109] After obtaining the average clipping ratio of non-target sub-segments, the corrected display ratio of each non-target sub-segment can be calculated based on the initial display ratio and the average clipping ratio of the non-target sub-segments. The specific steps are as follows:

[0110] S102-3-3-1: Determine the relationship between the initial display ratio and the average clipping ratio of each non-target sub-segment.

[0111] In this embodiment, since the initial display ratio of each non-target sub-segment is different, it is necessary to determine the relationship between the initial display ratio of the non-target sub-segment and the average clipping ratio in order to eliminate the situation where the initial display ratio is less than the average clipping ratio.

[0112] S102-3-3-2: When the initial display ratio of all non-target sub-segments is greater than the average clipping ratio, the corrected display ratio of each non-target sub-segment is obtained based on the initial display ratio and the average clipping ratio of the non-target sub-segments.

[0113] In this embodiment, if the initial display ratio of non-target sub-segments is greater than the average clipping ratio, the average clipping ratio can be directly subtracted from the initial display ratio of the target sub-segments to obtain the corrected display ratio of the non-target sub-segments.

[0114] S102-3-3-3: When the initial display ratio of non-target sub-segments is less than or equal to the average clipping ratio, calculate the weight clipping ratio of non-target sub-segments based on the preset weight ratio of non-target sub-segments, and obtain the corrected display ratio of each non-target sub-segment based on the initial display ratio and weight clipping ratio of non-target sub-segments.

[0115] In this embodiment, if the initial display ratios of all non-target sub-segments are less than or equal to the average clipping ratio, the initial display ratio will be less than or equal to zero. Therefore, the method of embodiment S102-3-3-2 cannot be used. In this case, the weighted clipping ratio of the non-target sub-segments can be calculated based on the preset weight ratio. The weight ratio can be understood as the ratio of the display ratio of any non-target sub-segment to all remaining non-target sub-segments, i.e., weight ratio a = display ratio of non-target sub-segments b / sum of display ratios of all non-target sub-segments c. After obtaining the sum of weight ratios corresponding to each non-target sub-segment, the weighted clipping ratio of each non-target sub-segment is calculated based on the weight ratio, i.e., weighted clipping ratio d of the non-target sub-segment d = (general compensation display ratio z + vehicle logo occupancy compensation display ratio y) * weight ratio a. Then, the weighted clipping ratio is directly subtracted from the initial display ratio of the non-target sub-segments to obtain the corrected display ratio of the non-target sub-segments.

[0116] S102-4: Generate corrected display images of the target sub-segment and the non-target sub-segment based on the corrected display ratio of the target sub-segment and the non-target sub-segment.

[0117] In this embodiment, after obtaining the corrected display ratio of the target sub-segment and the corrected display ratio of the non-target sub-segment, the corrected display images of the target sub-segment and the non-target sub-segment can be generated according to the corrected display ratio. The corrected display image of the target sub-segment has a larger viewing range than the initial display image of the target sub-segment, while the corrected display image of the non-target sub-segment has a smaller viewing range than the initial display image because it has less impact on the user's current road condition judgment. This achieves dynamic adjustment of the target sub-segment display image.

[0118] S103: Based on the corrected display images of the target sub-segment and the non-target sub-segment, correct the initial map bar chart to obtain the corrected map bar chart.

[0119] In this embodiment, the initial map bar chart is corrected to obtain a corrected map bar chart after dynamically adjusting the display images of the target sub-segment and non-target sub-segments. The corrected map bar chart can more intuitively reflect the road condition information and distance information of the target sub-segment where the vehicle is currently located, helping the user to make correct vehicle control judgments.

[0120] The steps to correct the initial map bar chart and obtain the corrected map bar chart are as follows:

[0121] According to the road segment number, replace the initial display images of the target sub-segment and non-target sub-segment in the initial map bar chart with the corresponding corrected display images.

[0122] In this embodiment, according to the road segment number, the sub-road segments of the initial map bar chart are sequentially replaced from the initial display image to the corrected display image. After the replacement is completed, the corrected map bar chart can be generated. Figure 3 As shown, Figure 3 This is the corrected map bar chart after modification.

[0123] S104: Display the corrected map bar chart as the target map bar chart.

[0124] In this embodiment, after generating the corrected map bar chart, it is used as the target map bar chart and displayed to the user through the vehicle's multimedia display device, thereby helping the user to obtain road condition information correctly and intuitively.

[0125] This invention also provides a map bar chart display device, referring to... Figure 4 The diagram illustrates a functional block diagram of a map bar chart display device according to the present invention. The device may include the following modules:

[0126] The first image module 401 is used to generate an initial map bar chart based on the traffic status of the target road segment, wherein the target road segment is composed of multiple sub-road segments with different traffic statuses;

[0127] The second image module 402 is used to generate corrected display images of the target sub-segment and non-target sub-segments, wherein the target sub-segment is the sub-segment where the vehicle is currently located, and there are multiple non-target sub-segments;

[0128] The correction module is used to correct the initial map bar chart based on the corrected display images of the target sub-segment and the non-target sub-segment to obtain the corrected map bar chart.

[0129] The display module is used to display the corrected map bar chart as the target map bar chart.
