Technical Field

[0001] This invention relates to the field of road driving, and more specifically, to a method, system, device, and storage medium for reminding drivers to drive safely. Background Technology

[0002] When driving on urban roads, especially when passing through traffic nodes such as intersections, vehicles often have a high probability of accidents due to practical problems such as obstructed vision and unclear traffic information ahead. The biggest factor leading to accidents is pedestrians crossing the road. Currently, there is no technology that can display information about pedestrians or vehicles crossing the road based on the level of danger, and provide drivers with suggestions on a reasonable driving speed when there are no pedestrians or vehicles crossing the road. Summary of the Invention

[0003] In view of this, the purpose of this invention is to provide a method, system, electronic device, and computer-readable storage medium for prompting drivers to drive safely. This invention utilizes multi-sensor fusion perception technology, deploys a perception system on the road, and simultaneously uses the cloud to perform fusion calculations on roadside perception results and sends relevant traffic dynamic information to targeted display devices deployed at intersections. This provides drivers crossing intersections with assisted driving prompts, including pedestrian crossing reminders and tips for efficient intersection crossing, thereby avoiding potential accidents and improving urban traffic efficiency.

[0004] To achieve the above objectives, one aspect of the present invention provides a method for prompting drivers to drive safely, comprising the following steps: collecting traffic information data of a target area and determining the location of traffic participants based on the traffic information data; detecting whether there are persons or vehicles in the target area corresponding to the direction of travel indicated by the lane indicator light that are inconsistent with the direction of travel; in response to the presence of persons or vehicles in the target area that are inconsistent with the direction of travel, displaying a warning sign on the display device corresponding to the lane indicator light; and in response to the absence of persons or vehicles in the target area that are inconsistent with the direction of travel, displaying an optimal travel speed on the display device corresponding to the lane indicator light.

[0005] In some implementations, the step of detecting whether there are people or vehicles in the target area corresponding to the direction of travel indicated by the lane indicator light that are inconsistent with the direction of travel includes: dividing the target area into a driving area and a non-driving area according to the direction of travel; detecting whether there are people or vehicles in the driving area and / or the non-driving area that are inconsistent with the direction of travel; and determining an alarm level according to the position and direction of travel of the people or vehicles in the driving area and / or the non-driving area in response to the presence of people or vehicles in the driving area and / or the non-driving area.

[0007] In some implementations, the step of determining the alarm level based on the location and direction of travel of the person or vehicle includes: determining the current alarm level as Level 1 in response to the existence of a person or vehicle moving in a non-driving area and capable of reaching the driving area within a preset time; determining the current alarm level as Level 2 in response to the absence of a person or vehicle corresponding to a Level 1 alarm and the existence of a person or vehicle moving in the driving area but unable to reach the non-driving area within a preset time or stationary in the driving area; determining the current alarm level as Level 3 in response to the absence of persons or vehicles corresponding to Level 1 and Level 2 alarms and the existence of persons or vehicles moving in the driving area but unable to reach the driving area within a preset time or stationary in the non-driving area; and determining the current alarm level as Level 4 in response to the absence of persons or vehicles corresponding to Level 1, Level 2, and Level 3 alarms and the existence of persons or vehicles moving in the non-driving area but unable to reach the driving area within a preset time or stationary in the non-driving area.

[0009] In some implementations, the step of displaying the optimal traffic speed on the display device corresponding to the lane indicator light in response to the absence of any person or vehicle in the target area that is not traveling in the same direction as the traffic vehicle includes: calculating whether the traffic vehicle can pass through the intersection based on the remaining green light duration, the current speed of the traffic vehicle, and the current position of the traffic vehicle; and displaying the minimum and maximum traffic speeds on the display device corresponding to the lane indicator light in response to the traffic vehicle being able to pass through the intersection.

[0010] In some implementations, in response to the presence of a person or vehicle in the target area that is not in the direction of travel, a warning sign is displayed on the display device corresponding to the lane indicator light; in response to a vehicle being unable to pass through the intersection, a suggested stop and wait sign is displayed on the display device corresponding to the lane indicator light.

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to specific examples and the accompanying drawings.

[0022] It should be noted that all uses of "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of the present invention. Subsequent embodiments will not explain this in detail.

[0023] In a first aspect, an embodiment of a method for prompting drivers to drive safely is provided. Figure 1 The diagram shown is an embodiment of the method for reminding drivers to drive safely provided by the present invention. Figure 1 As shown, the embodiments of the present invention include the following steps:

[0024] S1. Collect traffic information data of the target area and determine the location of traffic participants based on the traffic information data;

[0025] S2. Detect whether there are people or vehicles in the target area corresponding to the direction of travel indicated by the lane indicator light that are not in the direction of travel;

[0026] S3. In response to the presence of a person or vehicle in the target area that is not in the direction of travel, a warning sign is displayed on the display device corresponding to the lane indicator light; and

[0027] S4. In response to the absence of people or vehicles in the target area that are not in the same direction of travel, the optimal traffic speed is displayed on the display device corresponding to the lane indicator light.

[0028] Figure 2 This is a schematic diagram of a traffic intersection provided by the present invention, combined with... Figure 2 The embodiments of the present invention will be described.

[0029] Traffic information data of the target area is collected, and the location of traffic participants is determined based on the traffic information data. In this embodiment of the invention, the traffic information data includes image data and point cloud data. The camera's intrinsic and extrinsic parameters are calibrated, and image data is collected using the calibrated camera. The extrinsic parameters of the lidar are calibrated, and point cloud data is collected using the calibrated lidar. This embodiment of the invention can acquire dynamic traffic information within a certain range of an intersection using multiple types of sensors adapted to the characteristics of different intersections and road segments in a city, and simultaneously transmit the relevant information to the cloud.

[0030] The system detects whether there are any people or vehicles in the target area corresponding to the direction of travel indicated by the lane indicator light that are not in the direction of travel. The most dangerous area is determined based on the direction of travel; this is the target area in this embodiment of the invention. Detecting the target area instead of the entire area reduces computational load and improves detection accuracy.

[0031] In some embodiments, the step of detecting whether there are people or vehicles in the target area corresponding to the direction of travel indicated by the lane indicator light that are inconsistent with the direction of travel includes: dividing the target area into a driving area and a non-driving area according to the direction of travel; detecting whether there are people or vehicles in the driving area and / or the non-driving area that are inconsistent with the direction of travel; and, in response to the presence of people or vehicles in the driving area and / or the non-driving area that are inconsistent with the direction of travel, determining an alarm level based on the position and direction of travel of the people or vehicles. Figure 2 The example shown illustrates a scenario where the north-south straight-ahead direction has a green light while all other directions have red lights. Figure 2 Area 1 is the area where vehicles normally travel; therefore, in this embodiment of the invention, Area 1 is designated as a driving area. Area 2 is not the area where vehicles normally travel (for simplicity, lane changes at intersections are not considered); therefore, in this embodiment of the invention, Area 2 is designated as a non-driving area. In this embodiment of the invention, the presence of people or vehicles in the driving area and / or non-driving area that are not traveling in the same direction as the vehicles means that there are stationary people or vehicles in the driving area and / or non-driving area that are not traveling in the same direction as the normal traffic flow. Taking the previous north-straight route as an example, the presence of people or vehicles in the driving area and / or non-driving area that are not traveling in the same direction as the vehicles means that there are stationary people or vehicles in the driving area and / or non-driving area that are not traveling north-straight.

[0032] In some implementations, the step of detecting whether there are people or vehicles in the driving area and / or non-driving area that are inconsistent with the driving direction includes: determining the direction of movement of the person or vehicle based on the position of the same person or vehicle at multiple consecutive moments, and determining whether the direction of movement is the same as the driving direction. For example, if a person is in the same position for multiple consecutive moments, it indicates that the person is stationary; if a person is moving for multiple consecutive moments and the position is gradually moving to the right, it indicates that the person's direction of movement is to the right. Preferably, the person or vehicle may move first and then come to a stop, or come to a stop first and then move, so detecting the position at two consecutive moments can most accurately determine the direction of movement.

[0033] In some embodiments, the step of determining the alarm level based on the position and direction of movement of the person or vehicle includes: in response to the presence of a person or vehicle moving in a non-driving area and capable of reaching the driving area within a preset time, determining the current alarm level as Level 1. In this embodiment of the invention, the direction of movement and the upcoming position of the person or vehicle can be predicted based on the trajectory of the person or vehicle, and accordingly it can be determined whether the person or vehicle can reach the driving area from the non-driving area within a preset time. Since moving from the non-driving area to the driving area presents the greatest possibility of an accident, the alarm level is set to the highest level, namely Level 1. For example, if a person moves from area 2 to area 1 on the left side of a pedestrian crossing, it is very likely to collide with a vehicle traveling normally in area 1, then the current alarm level is determined to be Level 1.

[0034] In some implementations, the step of determining the alarm level based on the location and direction of travel of the person or vehicle includes: in response to the absence of a person or vehicle corresponding to a Level 1 alarm and the presence of a person or vehicle moving within the driving area and unable to reach a non-driving area within a preset time, or a person or vehicle stationary within the driving area, the current alarm level is determined to be Level 2. The determination of the alarm level follows the principle of maximum severity, i.e., if there is a Level 1 alarm behavior, the alarm level is Level 1; if there is no Level 1 alarm behavior but there is a Level 2 alarm behavior, the alarm level is Level 2, and so on. For example, if a person is stationary on a pedestrian crossing in Area 1, or if a person is moving on a pedestrian crossing in Area 1 and is predicted to be unable to reach Area 2 within a preset time, the current alarm level is determined to be Level 2.

[0035] In some implementations, the step of determining the alarm level based on the location and direction of movement of the person or vehicle includes: in response to the absence of a person or vehicle corresponding to a Level 1 or Level 2 alarm, and the presence of a person or vehicle moving within the driving area and capable of reaching a non-driving area within a preset time, determining the current alarm level as Level 3. For example, if a person moves from area 1 to area 2 on the left or to area 2 on the right at a pedestrian crossing, the current alarm level is determined to be Level 3.

[0036] In some implementations, the step of determining the alarm level based on the location and direction of travel of the person or vehicle includes: in response to the absence of a person or vehicle corresponding to a Level 1, Level 2, or Level 3 alarm, and the presence of a person or vehicle moving in a non-driving area and unable to reach a driving area within a preset time, or stationary in a non-driving area, determining the current alarm level as Level 4. For example, if a person is stationary on a pedestrian crossing in Area 2, or if a person is moving on a pedestrian crossing in Area 2 and is predicted to be unable to reach Area 1 within a preset time, then the current alarm level is determined to be Level 4.

[0037] In response to the presence of a person or vehicle in the target area that is not in the direction of travel, a warning sign is displayed on the display device corresponding to the lane indicator light.

[0038] In some embodiments, the step of displaying a warning indicator on the display device corresponding to the lane indicator light includes: displaying a warning indicator corresponding to the current warning level on the corresponding display device. For example, level one can display ①, level two can display ②, level three can display ③, and level four can display ④. Of course, this is just an example, and other warning indicators can be used in other embodiments.

[0039] In response to the absence of any person or vehicle traveling in the opposite direction in the target area, the optimal traffic speed is displayed on the display device corresponding to the lane indicator light.

[0040] In some implementations, the step of displaying the optimal traffic speed on the display device corresponding to the lane indicator light in response to the absence of people or vehicles traveling in the target area in the opposite direction of travel includes: calculating whether the vehicle can pass through the intersection based on the remaining green light duration, the current speed of the vehicle, and its current position; and displaying the minimum and maximum traffic speeds on the display device corresponding to the lane indicator light in response to the vehicle being able to pass through the intersection. Alternatively, the calculation can be based on the maximum permissible speed on the current road to determine whether the vehicle can cross the stop line within the remaining green light duration. If it can cross the stop line, then the minimum and maximum traffic speeds are displayed on the display device corresponding to the lane indicator light.

[0041] In some implementations, the step of displaying a warning sign on the display device corresponding to the lane indicator light in response to the presence of a person or vehicle in the target area that is not traveling in the same direction as the traffic flow includes: displaying a suggested stop and wait sign on the display device corresponding to the lane indicator light in response to a vehicle being unable to pass through the intersection. If a vehicle cannot pass the stop line within the remaining time of the green light, then a suggested stop and wait sign is displayed on the display device corresponding to the lane indicator light.

[0042] It should be particularly noted that the steps in each embodiment of the above-mentioned method for reminding drivers to drive safely can be interchanged, substituted, added, or deleted. Therefore, these reasonable permutations and combinations of the method for reminding drivers to drive safely should also fall within the protection scope of this invention, and the protection scope of this invention should not be limited to the embodiments.

[0049] In some embodiments, the second display module is further configured to: display a suggested stop and wait sign on the display device corresponding to the lane indicator light in response to a vehicle being unable to pass through the intersection.
