[0032] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0033] In this application, the terms "first", "second", etc. are used to distinguish identical or similar items with basically the same effects and functions. It should be understood that there is no logical or temporal dependency between "first", "second", and "nth", nor is there any limitation on quantity and execution order.

[0034] In the present application, the term "at least one" means one or more, and the term "plurality" means two or more.

[0035] It should be noted that the information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data used for analysis, stored data, displayed data, etc.) and signals involved in this application are all authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant laws, regulations and standards of relevant countries and regions.

[0036] Figure 1 is a schematic diagram of an implementation environment of a driving reminder method provided according to an embodiment of the present application, see Figure 1 The implementation environment includes: a vehicle-mounted terminal 101, a vehicle-mounted camera 102 and a vehicle-mounted large screen 103.

[0037] The vehicle-mounted terminal 101 is an electronic device installed on the vehicle. The vehicle-mounted terminal 101 integrates multiple functions and can interact with various systems of the vehicle and external networks. For example, the vehicle-mounted terminal 101 can be a TBOX (Telematics Box), that is, a remote communication terminal on the vehicle that integrates the vehicle body network and wireless communication functions. The vehicle-mounted terminal 101 has a positioning and navigation function. By receiving the satellite signal of the navigation system, the vehicle's location information can be accurately determined, thereby providing navigation services for the driver.

[0038] The vehicle-mounted camera 102 includes but is not limited to a front-view camera, a rear-view camera, a side-view camera, etc. installed on the vehicle. The vehicle-mounted camera 102 can provide clear images of the front, rear, or side of the vehicle, so that the vehicle-mounted terminal 101 or the driver can determine the road conditions based on the collected images.

[0039] The vehicle-mounted large screen 103 can be a display screen of the vehicle-mounted terminal 101, and is used to provide a human-computer interaction function. For example, the vehicle-mounted large screen 103 can display a navigation map, and display the current location of the vehicle on the navigation map, thereby providing navigation for the driver. Alternatively, the vehicle-mounted large screen can also display images captured by the vehicle-mounted camera 102, so that the driver can judge the road conditions around the vehicle based on the images, thereby better assisting the driver in driving the vehicle.

[0040] Figure 2 is a flow chart of a driving reminder method provided according to an embodiment of the present application, such as Figure 2 As shown, taking the method executed by the vehicle terminal as an example, the method includes the following steps:

[0041] 201. The vehicle-mounted terminal obtains environmental information of the vehicle, where the environmental information includes at least one of location data and a road image.

[0042] In an embodiment of the present application, the location data is used to indicate the specific location of the vehicle. Optionally, the vehicle-mounted terminal can obtain the location data of the vehicle from a navigation system, such as a global positioning system (GPS) or a Beidou satellite navigation system. The above-mentioned satellite navigation system transmits signals through multiple satellites, and after the vehicle-mounted terminal receives the signals, it can use algorithms such as triangulation to calculate the precise location of the vehicle. The location data obtained in the above manner has a high positioning accuracy, and generally can reach meter-level accuracy. For example, on a multi-lane urban main road or highway, the vehicle-mounted terminal can accurately determine the lane where the vehicle is currently located based on the precise location data, providing data support for subsequent driving reminders.

[0043] The road image may be an image of the road taken by the vehicle's onboard camera, and the road image usually includes lane lines. The onboard camera may be installed in front, at the rear or at the side of the vehicle. While the vehicle is driving, the onboard camera can capture the surrounding roads at a certain frame rate to obtain a road image. Lane lines refer to traffic markings on the road used to separate different lanes or indicate the direction of vehicle travel, such as white dotted lines, white solid lines, yellow lines, etc. Optionally, the onboard terminal can communicate data with the onboard camera through bus, Ethernet, wireless communication, etc., to obtain the road image captured by the onboard camera.

[0044] 202. The vehicle-mounted terminal determines a driving lane of the vehicle based on the vehicle's environmental information.

[0045] In the embodiment of the present application, when the acquired environmental information includes high-precision location data, the vehicle-mounted terminal can determine the vehicle's driving lane, that is, the lane the vehicle is currently in, based on the location data and the lanes marked on the map. In addition, when the environmental information includes a road image, the vehicle-mounted terminal can also determine the vehicle's driving lane by identifying lane lines in the road image.

[0046] Optionally, lane lines include but are not limited to lane dividing lines, lane edge lines, etc. Lane dividing lines are used to separate vehicles traveling in the same direction, and are generally white dotted lines. Vehicles can cross the line to change lanes while ensuring safety. For example, on urban expressways or highways, when a vehicle needs to overtake or change lanes, it can cross the white dotted line to change lanes after confirming safety. Lane edge lines are used to indicate the edge position of the lane, and are generally white solid lines. They are mainly used to clarify the boundaries of the lanes, keep vehicles in the specified lanes, and ensure driving safety and order.

[0047] 203. When the vehicle's driving speed is lower than the first speed for a first period of time, the vehicle terminal outputs a reminder message, where the first speed is the minimum driving speed of the driving lane, and the reminder message is used to remind the driver to increase the driving speed or change lanes.

[0048] In the embodiment of the present application, after determining the driving lane of the vehicle, the vehicle terminal can determine whether the current driving speed of the vehicle is lower than the minimum driving speed of the driving lane. If the driving speed of the vehicle is continuously lower than the minimum driving speed, it indicates that the current driving speed of the vehicle is slow, which is likely to affect the vehicles behind or cause road congestion. Therefore, the vehicle terminal outputs a reminder message to prompt the driver to increase the speed or change lanes, such as increasing the speed to above the minimum driving speed, or changing to a slow lane. Among them, the minimum driving speed and the first duration of the lane can be set according to the actual situation, such as the minimum driving speed is 80 kilometers per hour, the first duration is 5 seconds or 10 seconds, etc., and the embodiment of the present application does not limit this.

[0049] The embodiment of the present application provides a driving reminder method, which can accurately identify the lane where the vehicle is located based on the vehicle position data or the collected image containing the lane lines, and then when the vehicle speed continues to be lower than the minimum speed limit requirement of the lane, timely output reminder information to remind the driver to increase the speed or change lanes, thereby avoiding traffic congestion or rear-end collisions caused by low-speed driving in the fast lane, especially in the scenarios of highways or urban expressways, can effectively reduce the traffic safety risks caused by the mismatch between vehicle speed and lane, and can improve driving safety while ensuring road traffic efficiency.

[0050] Figure 3 is a flow chart of another driving reminder method provided according to an embodiment of the present application. Figure 3 As shown, taking the method executed by the vehicle terminal as an example, the method includes the following steps:

[0051] 301. The vehicle-mounted terminal obtains environmental information of the vehicle, where the environmental information includes at least one of location data and a road image.

[0052] In the embodiment of the present application, the vehicle can obtain environmental information through the vehicle terminal and the vehicle camera. Among them, the vehicle terminal can obtain the vehicle's location data from the navigation system. The positioning accuracy of the location data is high, generally reaching meter-level accuracy, so that the vehicle terminal can determine the vehicle's driving lane based on the high-precision location data. The vehicle camera can capture road images in front of, behind or to the side of the vehicle. The road image usually includes lane lines, so that the vehicle terminal can determine the vehicle's driving lane based on the lane lines.

[0053] In some embodiments, the vehicle-mounted terminal can obtain the vehicle's environmental information in real time when the driving reminder function is turned on, so as to determine the vehicle's driving lane based on the environmental information, and then output reminder information when it is detected that the vehicle is driving at a low speed in the fast lane for a long time, so as to realize the driving reminder. Accordingly, in response to the operation of turning on the driving reminder function, the vehicle-mounted terminal obtains the vehicle's environmental information in real time. For example, the vehicle-mounted terminal can display the driving reminder function on button. The on button is used to turn on the driving reminder function after triggering. In addition, the vehicle-mounted terminal can also display the driving reminder function off button so that the driver can manually turn off the driving reminder function as needed. By obtaining the vehicle's environmental information when the driving reminder function is turned on, it is possible to avoid the reduction of vehicle endurance due to the continuous acquisition of vehicle environmental information, and it is also possible to avoid the driving reminder function interfering with the driver's driving of the vehicle, thereby improving driving safety.

[0054] 302. The vehicle-mounted terminal determines a driving lane of the vehicle based on the vehicle's environmental information.

[0055] In an embodiment of the present application, when the acquired environmental information includes location data, the vehicle-mounted terminal can determine the vehicle's driving lane, that is, the lane where the vehicle is currently located, based on the location data and in combination with the lanes marked on the navigation map. In the case where the environmental information includes a road image, the vehicle-mounted terminal can also determine the vehicle's driving lane by identifying the lane lines in the road image. Among them, lane lines include but are not limited to lane dividing lines, lane edge lines, etc. Lane dividing lines are used to separate traffic flows traveling in the same direction, and are generally white dotted lines. Vehicles can cross the line to change lanes while ensuring safety. For example, on urban expressways or highways, when a vehicle needs to overtake or change lanes, it can cross the white dotted line to change lanes after confirming safety. The lane edge line is used to indicate the edge position of the lane, mainly to clarify the boundary of the lane so that the vehicle can stay in the specified lane, and is generally a white solid line. Vehicles must not cross the white solid line to ensure driving safety and order.

[0056] In some embodiments, when the environmental information includes position data and road images, the vehicle terminal can determine the driving lane of the vehicle based on the position data and the road image respectively. If the driving lanes indicated by the two are consistent, the vehicle terminal determines the driving lane as the lane where the vehicle is located; if the driving lanes indicated by the two are inconsistent, the vehicle terminal re-acquires the environmental information and determines the driving lane of the vehicle again based on the environmental information until the driving lanes indicated by the two are consistent, thereby ensuring the accuracy of lane positioning.

[0057] 303. When the lane type of the driving lane is a preset type, the vehicle-mounted terminal determines whether congestion occurs on the road section where the vehicle is located.

[0058] In the embodiment of the present application, the preset types include but are not limited to the left lane, the middle lane, etc. Among them, the left lane is usually the overtaking lane, also known as the fast lane. The middle lane is the driving lane. The driving speed of vehicles on the left lane is generally higher than the driving speed of vehicles on the middle lane, and the driving speed of vehicles on the middle lane is generally higher than the driving speed of vehicles on the right lane, so the right lane is also usually called the slow lane. When the vehicle is currently driving in the left lane or the middle lane, the driving speed of the vehicle should not be too slow to avoid causing traffic congestion or traffic accidents.

[0059] Optionally, when the driving reminder function is turned on, if the vehicle is driving at a low speed for a long time on the above lane, the vehicle-mounted terminal outputs a reminder message to remind the driver to increase the speed or change lanes. However, if the road section where the vehicle is located has been congested, such as encountering a traffic jam on a highway, it will also be detected that the vehicle is driving at a low speed for a long time on a preset type of lane. Therefore, in order to avoid false reminders in the above situation, in some embodiments, the vehicle-mounted terminal can collect road section images through the vehicle's on-board camera. Among them, the road section image is used to indicate the number of vehicles in the road section where the vehicle is located. For example, the road section image can be an image collected by a front-view camera, which can reflect the number of vehicles located in front of the vehicle on the current lane. Or, the road section image can be an image collected by a rear-view camera, which can reflect the number of vehicles located behind the vehicle on the current lane. When the number of vehicles in the road section is greater than the preset number, the vehicle-mounted terminal determines that the road section is congested. Among them, the preset number can be set according to actual conditions, and the embodiment of the present disclosure does not limit this. Since the on-board camera can collect images of the road sections around the vehicle in real time and obtain the traffic conditions in front of or behind the vehicle in a timely manner, it can determine the current actual road conditions more quickly than through traffic broadcasts, static road condition monitoring and other methods, and accurately determine the actual congestion situation of the road section.

[0060] In some embodiments, when the number of vehicles in the road section is greater than the preset number, the vehicle-mounted terminal can further determine the speed of at least one other vehicle in the road section or the distance between at least one other vehicle and the vehicle. Optionally, the vehicle-mounted terminal can determine the distance between other vehicles and the vehicle through a ranging radar installed on the vehicle. Alternatively, the vehicle-mounted terminal can obtain the speed of other vehicles on the current lane through vehicle-to-vehicle (V2V) communication technology. When the speed of at least one other vehicle is lower than the second speed, it indicates that the speed of most vehicles on the lane is slow, so the vehicle-mounted terminal determines that the current road section is congested. Alternatively, when the distance between at least one other vehicle and the vehicle is less than the preset distance, it indicates that the distance between vehicles on the lane is small, so the vehicle-mounted terminal determines that the road section is congested. Among them, the second speed and the preset distance can be set according to the actual situation, and the embodiment of the present application does not limit this. By further determining whether the road section is congested according to the speed of other vehicles on the lane and the distance between other vehicles and the vehicle, the accuracy of determining the congestion of the road section can be improved as much as possible.

[0061] 304. In response to the duration of the vehicle's driving speed being lower than the first speed reaching a first duration, when there is no congestion on the road section, the vehicle-mounted terminal outputs a reminder message, where the reminder message is used to remind the vehicle to increase the driving speed or change lanes.

[0062] In the embodiment of the present application, the preset type of driving lane usually has a minimum driving speed. The first speed is also the minimum driving speed of the vehicle's driving lane. For example, for the left lane, on a road with two lanes in the same direction, the minimum driving speed of the left lane is 90 kilometers per hour; on a road with three or more lanes in the same direction, the minimum speed of the left lane is 100 kilometers per hour. For the middle lane, its minimum driving speed can be 80 kilometers per hour.

[0063] If the vehicle's speed is continuously lower than the minimum speed of the current lane when there is no congestion on the road where the vehicle is located, it indicates that the vehicle's current speed is slow and may affect the vehicle behind or cause congestion on the road, so the vehicle terminal outputs a reminder message. Optionally, the vehicle terminal may display or broadcast the reminder message to remind the driver to increase the speed or change lanes as much as possible.

[0064] In some embodiments, in order to ensure driving safety, the vehicle terminal can also determine the weather conditions in the area where the vehicle is located based on the vehicle's location data. When the weather condition is not any of the preset weather conditions, in response to the duration of the vehicle's driving speed being lower than the first speed reaching the first duration, the vehicle terminal outputs a reminder message. Among them, the preset weather can be severe weather such as rainy and snowy weather, hail weather, and haze weather, which are prone to traffic accidents. If the weather condition in the area where the vehicle is located is any of the above preset weather conditions, even if the vehicle's driving speed continues to be lower than the first speed, the vehicle terminal will not output a reminder message to avoid traffic accidents caused by high vehicle speed in severe weather, thereby ensuring driving safety as much as possible.

[0065] 305. When the vehicle's driving speed is not lower than the first speed, or when the vehicle changes lanes and the vehicle's driving speed is not lower than the minimum driving speed of the changed lane, the vehicle-mounted terminal cancels outputting the reminder information.

[0066] In the embodiment of the present application, after the vehicle terminal outputs the reminder information, if the vehicle's driving speed is not lower than the first speed, it indicates that the vehicle's speed meets the speed requirement of the current lane, so the vehicle terminal cancels the output of the reminder information, such as canceling the display or broadcasting of the reminder information. Alternatively, if the vehicle changes lanes after the vehicle terminal outputs the reminder information, and the vehicle's speed is not lower than the minimum driving speed of the changed lane, the vehicle terminal can also cancel the output of the reminder information to avoid the reminder information interfering with the driver's driving of the vehicle.

[0067] In some embodiments, if the vehicle's driving speed is still lower than the minimum driving speed of the current lane when the reminder information is output for a certain period of time, the vehicle terminal can strengthen the reminder method. For example, the vehicle terminal originally uses the first volume to broadcast the reminder information. When the broadcasting time of the reminder information reaches the second time, the vehicle terminal uses the second volume to broadcast the reminder information. The second volume is higher than the first volume, that is, the vehicle terminal increases the playback volume of the reminder information to urge the driver to increase the speed or change lanes as much as possible, so as to avoid affecting the rear vehicles or causing road congestion.

[0068] The embodiment of the present application provides a driving reminder method, which can accurately identify the lane where the vehicle is located based on the vehicle position data or the collected image containing the lane lines, and then when the vehicle speed continues to be lower than the minimum speed limit requirement of the lane, timely output reminder information to remind the driver to increase the speed or change lanes, thereby avoiding traffic congestion or rear-end collisions caused by low-speed driving in the fast lane, especially in the scenarios of highways or urban expressways, can effectively reduce the traffic safety risks caused by the mismatch between vehicle speed and lane, and can improve driving safety while ensuring road traffic efficiency.

[0081] In some embodiments, the reminder module 403 is used to cancel the output of the reminder information when the vehicle's driving speed is not lower than the first speed; or, when the vehicle changes lanes and the vehicle's driving speed is not lower than the minimum driving speed of the changed lane, cancel the output of the reminder information.
