[0045] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0046] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application, and thus the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0047] In the following description, a large number of details are discussed to provide a more thorough explanation of the embodiments of the present application. However, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present application difficult to understand.

[0048] Combine the following Figures 1 to 6 , the lane change prompt method, device, vehicle and system provided in this application are explained.

[0049] See also Figure 1 , Figure 1 A flowchart of a lane change prompt method provided in an embodiment of the present application is shown as follows: Figure 1 As shown, the method includes:

[0050] S110: Receive target closed lane information sent by a cloud server (Server), the target closed lane information including: starting position information and end position information of the closed lane, the starting position information is sent to the cloud server by a first signal generator preset at the starting point of the closed lane, and the end position information is sent to the cloud server by a second signal generator preset at the end point of the closed lane.

[0051] It is understandable that by setting the first signal generator at the starting point of the closed lane and the second signal generator at the end point of the closed lane, the real-time collection and uploading of the starting point position information and the end point position information of the closed lane can be better achieved without manual uploading, thus avoiding the time delay caused by manual uploading. Moreover, even if the first signal generator and / or the second signal generator are adjusted in position, the first signal generator and the second signal generator can send the adjusted position information to the cloud server in time, thereby realizing information synchronization, which is highly real-time.

[0052] In addition, by uploading the starting point location information and the end point location information of the closed lane to the cloud server, the cloud server can easily distribute the received starting point location information and the end point location information to vehicles traveling on or about to travel to the road where the closed lane is located.

[0053] It is understandable that if the first signal generator or the second signal generator directly transmits the location information of the closed lane to the vehicle closest to it, and then the vehicle transmits the location information of the closed lane to the vehicle closest to it, it may cause the vehicle that receives the information later to fail to respond in time, which may cause certain safety hazards. However, the above method can distribute the target closed lane information to vehicles traveling on or about to travel to the road where the closed lane is located by using the cloud server to distribute and transmit information, so that each vehicle can respond to the target closed lane information in time, such as changing lanes or slowing down.

[0054] In some examples of this embodiment, the first signal generator and the second signal generator may be a roadside unit (RSU) or the like.

[0055] S120: Based on the target closed lane information, a lane change prompt is issued to prompt the driver to change lanes.

[0056] In some examples of this embodiment, the lane change prompt may be in the form of text, sound, vibration or light.

[0057] In some embodiments, the target closed lane information also includes length information of the closed lane, and the length information is determined by the cloud server based on the starting point position information and the end point position information.

[0058] It is understandable that the cloud server can obtain the length information of the closed lane based on the starting position information and the end position information of the closed lane. By obtaining the length information of the closed lane, it is convenient for the vehicle to adjust the driving strategy, such as adjusting the driving mode based on the length information of the closed lane.

[0059] In some embodiments, based on the target closed lane information, a lane change prompt is issued to prompt the driver to change lanes, including:

[0060] 1. Determine a closed lane based on the starting point position information and / or the end point position information.

[0061] It can be understood that the closed lane can be obtained based on the lane where the starting position information and / or the end position information are located.

[0062] 2. Determine the remaining lanes of the road where the closed lane is located as available lanes.

[0063] 3. If the vehicle is traveling in the closed lane, a lane change prompt is issued to prompt the driver to change lanes to any of the available lanes.

[0064] It can be understood that through the above method, the driver can be prompted to change lanes in time.

[0065] In some embodiments, if the vehicle is traveling in the closed lane, a lane change prompt is issued to prompt the driver to change lanes to any of the available lanes, including:

[0066] 1. Determine the distance between the vehicle and the starting point of the closed lane as a first distance.

[0067] 2. Determine the first time as a ratio between the first distance and the instantaneous speed of the vehicle.

[0068] 3. Determine a ratio between a preset lane change prompt distance and an instantaneous speed of the vehicle as the second time.

[0069] 4. The sum of the second time and the preset advance prompt time is determined as the third time.

[0070] 5. Determine the difference between the first time and the third time as the fourth time.

[0071] It can be understood that the first time is equivalent to the time required for the vehicle to travel to the starting point of the closed lane at the current instantaneous speed. The second time is equivalent to the time required for the vehicle to travel from the target position (assuming that the lane change prompt distance is a, the target position is determined by walking a distance from the starting point of the closed lane in the opposite direction of the vehicle's travel, and the position reached is the target position) to the starting point of the closed lane at the current instantaneous speed. The advance prompt time can be set according to actual needs, such as 10s (seconds).

[0072] 6. Determine the sum of the current system time and the fourth time as the lane change prompt time.

[0073] It is understandable that the system time refers to the time of the vehicle system. Through the above method, a better time for executing the lane change can be obtained, so that the driver can change the lane easily.

[0074] The mathematical expression for determining the lane change prompt time is: T = localtime + S / V - (S' / V + t), where T represents the lane change prompt time, localtime represents the current system time, S represents the first distance, V represents the current instantaneous speed of the vehicle, S' represents the lane change prompt distance, and t represents the advance prompt time. Assuming that the current advance prompt time is set to 10s, the lane change prompt can be issued 10s in advance before the vehicle reaches the starting point of the closed lane, so as to facilitate the driver to change lanes. Since the reaction speed of each driver is different, the advance prompt time can be set and adjusted according to actual needs to meet the prompt needs of different drivers, and it has strong adaptability.

[0075] 7. If the vehicle is traveling in the closed lane and the system time reaches the lane change prompt time, a lane change prompt is issued to prompt the driver to change lanes to any of the available lanes.

[0076] In some embodiments, if the vehicle is traveling in the closed lane, a lane change prompt is issued to prompt the driver to change lanes to any of the available lanes, further comprising:

[0077] If the system time does not reach the lane change prompt time, the lane change prompt time is updated regularly according to a preset update frequency based on the instantaneous speed and vehicle position of the vehicle until the system time reaches the lane change prompt time.

[0078] In some examples of this embodiment, the update frequency can be set according to actual needs, such as 1 time / second.

[0079] It is understandable that in real driving, vehicles often do not always maintain a constant speed, but may change speed, that is, the instantaneous speed and position of the vehicle will continue to change. Therefore, based on the changed instantaneous speed and position of the vehicle, a new lane change prompt time can be obtained, and the new lane change prompt time is more suitable for the current driving state of the vehicle. Subsequently, lane change prompts can be made based on the new lane change prompt time, with higher accuracy.

[0080] In some embodiments, if the vehicle is traveling in the closed lane and the system time reaches the lane change prompt time, a lane change prompt is issued to prompt the driver to change lanes to any of the available lanes, including:

[0081] 1. Obtain a speed signal of a target vehicle traveling on the available lane.

[0082] 2. If the target vehicle is located behind the current vehicle and the speed of the target vehicle is greater than or equal to the speed of the current vehicle, a deceleration prompt message is issued to prompt the driver to slow down. When the target vehicle drives to the front of the current vehicle and the distance between the target vehicle and the current vehicle is greater than or equal to the preset distance, the lane change prompt is issued.

[0083] It can be understood that through the above method, lane change prompts can be issued in a timely manner while ensuring the safety of the vehicle.

[0084] In some embodiments, the method further comprises:

[0085] 1. Receive lane closure notification information sent by other vehicles on the road where the closed lane is located, and the lane closure notification information includes: starting point position information and end point position information of the closed lane.

[0086] In some examples of this embodiment, the closed lane notification information may be target closed lane information transmitted by a cloud server to other vehicles on the road, or may be information collected by other vehicles on the road themselves.

[0087] 2. If the target closed lane information is different from the closed lane notification information, the target closed lane information or the closed lane notification information is determined as lane abnormality information based on a preset prompt rule.

[0088] It is understandable that if the target lane closure information is different from the lane closure notification information, it may be due to a communication anomaly between the current vehicle and the cloud server, resulting in data transmission error, or it may be due to a communication anomaly between the current vehicle and other vehicles, or it may be due to other vehicles detecting lane closure information that the cloud server failed to receive, etc. Therefore, based on the preset prompt rule, the target lane closure information or lane closure notification information can be determined as lane abnormality information. The prompt rule can be set according to actual conditions.

[0089] 3. Based on the lane abnormality information, issue the lane change prompt.

[0090] It can be understood that by issuing a lane change prompt based on the lane abnormality information, higher accuracy can be achieved.

[0091] Figure 2 This is an example diagram of an application scenario of the lane change prompt method provided in an embodiment of the present application. Please refer to Figure 2 In the case of road construction or traffic accidents, by setting a first signal generator 210 at the starting point of the closed lane and a second signal generator 220 at the end point of the closed lane, the real-time uploading of the position information of the closed lane can be realized, that is, the first signal generator 210 transmits the starting point position information of the closed lane to the cloud server 230, and the second signal generator 220 transmits the end point position information of the closed lane to the cloud server 230. The cloud server 230 sends the target closed lane information including the starting point position information and the end point position information of the closed lane to the vehicle traveling on or about to travel to the road where the closed lane is located, so that the vehicle can issue a lane change prompt in time according to the target closed lane information to prompt the driver to change the lane to an available lane (other lanes in the road where the closed lane is located except the closed lane). By applying the lane change prompt method in the above embodiment, the vehicle can change lanes in advance to avoid traffic congestion or traffic accidents.
