TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle control, and in particular to a lane change prompting method, device, vehicle and system. BACKGROUND

[0002] With the continuous development of intelligent transportation systems (ITS) and vehicle-to-everything (V2X) technologies, modern vehicles increasingly rely on real-time traffic information during driving to improve traffic safety and driving efficiency. Traditional traffic information collection usually relies on static maps and pre-recorded traffic information, and the frequency of updating for dynamically changing road conditions (such as construction, temporary traffic control, etc.) is low.

[0003] Therefore, the traffic collected in this way often has a certain time delay, especially after the occurrence of road state changes, the collection, processing and transmission of related information need a certain time to reach the vehicle end. Therefore, for some temporary and unforeseen road changes (such as sudden accidents or short-term road closures), it is difficult for the vehicle end to respond in time, resulting in an increase in the risk of accidents and congestion. SUMMARY

[0004] The present application provides a lane change prompting method, device, vehicle and system to solve the problem that in related technologies, for temporary and unforeseen road changes, the vehicle end is difficult to respond in time, resulting in an increase in the risk of accidents and congestion.

[0005] The present application provides a lane change prompting method, which comprises:

[0006] receiving target closed lane information sent by a cloud server, the target closed lane information comprising: start point position information and end point position information of a closed lane, the start point position information being sent by a first signal generator preset at the start point of the closed lane to the cloud server, and the end point position information being sent by a second signal generator preset at the end point of the closed lane to the cloud server;

[0008] In an embodiment of the present application, the target closed lane information further comprises length information of the closed lane, and the length information is determined by the cloud server based on the start point position information and the end point position information.

[0009] In an embodiment of the present application, based on the target closed lane information, a lane change prompt is sent to prompt the driver to change lanes, including:

[0012] If the vehicle is driving on the closed lane, a lane change prompt is sent to prompt the driver to change lanes to any of the available lanes.

[0013] In an embodiment of the present application, if the vehicle is driving on the closed lane, a lane change prompt is sent to prompt the driver to change lanes to any of the available lanes, including:

[0014] The distance between the vehicle and the start of the closed lane is determined as a first distance;

[0015] The ratio between the first distance and the instantaneous speed of the vehicle is determined as a first time;

[0016] The ratio between a preset lane change prompt distance and the instantaneous speed of the vehicle is determined as a second time;

[0017] The sum of the second time and a preset early prompt time is determined as a third time;

[0018] The difference between the first time and the third time is determined as a fourth time;

[0019] The sum of the current system time and the fourth time is determined as a lane change prompt time;

[0020] If the vehicle is driving on the closed lane and the system time reaches the lane change prompt time, a lane change prompt is sent to prompt the driver to change lanes to any of the available lanes.

[0021] In an embodiment of the present application, if the vehicle is driving on the closed lane, a lane change prompt is sent to prompt the driver to change lanes to any of the available lanes, further including:

[0022] If the system time does not reach the lane change prompt time, the lane change prompt time is updated periodically based on the instantaneous speed of the vehicle and the vehicle position according to a preset update frequency until the system time reaches the lane change prompt time.

[0023] In an embodiment of the present application, if the vehicle is driving on the closed lane and the system time reaches the lane change prompt time, a lane change prompt is sent to prompt the driver to change the lane to any available lane, including:

[0024] A speed signal of a target vehicle driving on the available lane is acquired.

[0025] If the target vehicle is located behind the vehicle body of 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 is sent to prompt the driver to decelerate, and when the target vehicle drives to the front of the vehicle body of the current vehicle and the distance between the target vehicle and the current vehicle is greater than or equal to a preset distance, the lane change prompt is sent.

[0026] In an embodiment of the present application, it further includes:

[0027] The closed lane notification information sent by other vehicles on the road where the closed lane is located is received, and the closed lane notification information includes start point position information and end point position information of the closed lane.

[0028] 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 abnormal information based on a preset prompt rule.

[0029] Based on the lane abnormal information, the lane change prompt is sent.

[0030] The present application also provides a lane change prompting device, comprising:

[0031] A closed lane information receiving module is configured to receive target closed lane information sent by a cloud server, wherein the target closed lane information includes start point position information and end point position information of the closed lane, the start point position information is sent to the cloud server by a first signal generator preset at the start point of the closed lane, and the end point position information is sent to the cloud server by a second signal generator preset at the end point of the closed lane.

[0032] A lane change prompting module is configured to send a lane change prompt based on the target closed lane information to prompt the driver to change the lane.

It can be understood that, for temporary road change conditions or unforeseen road change conditions, if a traditional traffic information uploading method, i.e., manually uploading traffic information and then processing and delivering the traffic information by navigation software, is used, the vehicle may not be able to timely respond due to information time delay. However, by using the method, the start point position information and the end point position information of the closed lane can be timely uploaded to the cloud server by using the first signal generator and the second signal generator, and the target closed lane information can be timely distributed to a vehicle traveling on or about to travel on a road where the closed lane is located by the cloud server, so that the real-time performance is relatively high. When the vehicle receives the target closed lane information, the vehicle can send a lane change prompting based on the target closed lane information, so as to timely prompt the driver to change lanes, avoid causing traffic congestion or traffic accidents, and effectively improve the driving experience.

[0045] The present application will be described in detail by specific embodiments, and those skilled in the art can easily understand other advantages and effects of the present application from the disclosure. The present application can also be implemented or applied by different specific embodiments, and various modifications or changes can be made to the details in the specification based on different views 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 diagrams provided in the following embodiments only illustrate the basic concept of the present application in a schematic manner, and only the components related to the present application are shown in the diagrams, not the number, shape and size of the components when actually implemented. The actual implementation of each component may be a random change in shape, number and proportion, and the layout pattern of the components may also be more complex.

[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, and in other embodiments, the 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] The following will be described in conjunction with Figures 1 to 6 The lane change prompting method, device, vehicle and system provided by the present application are explained and described.

[0049] Please refer to Figure 1 , Figure 1 A flowchart of a lane change prompting method provided by an embodiment of the present application is shown in the figure, as shown in the figure, the method comprises: Figure 1

[0050] ​S110: receiving target closed lane information sent by a cloud server, the target closed lane information comprising: start point position information and end point position information of the closed lane, the start point position information being sent by a first signal generator preset at a start point of the closed lane to the cloud server, and the end point position information being sent by a second signal generator preset at an end point of the closed lane to the cloud server.

[0051] It can be understood that by setting the first signal generator at the start point of the closed lane and the second signal generator at the end point of the closed lane, the start point position information and the end point position information of the closed lane can be well collected and uploaded in real time without manual uploading, avoiding 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 timely send the adjusted position information to the cloud server, so as to realize information synchronization and strong real-time performance.

[0052] In addition, by uploading the start point position information and the end point position information of the closed lane to the cloud server, the cloud server can distribute the received start point position information and end point position information to vehicles driving on or about to drive on the road where the closed lane is located.

[0053] It can be understood that if the first signal generator or the second signal generator directly transmits the position information of the closed lane to the nearest vehicle, and then the vehicle transmits the position information of the closed lane to the nearest vehicle, the vehicle receiving the information later may not be able to react in time, which may cause certain safety hazards. The above method can distribute the target closed lane information to vehicles driving on or about to drive on the road where the closed lane is located at the same time by using the cloud server for information distribution and transmission, so as to facilitate each vehicle to react to the target closed lane information in time, such as changing lanes or reducing speed.

[0054] In some examples of the embodiment, the first signal generator and the second signal generator can be road side units (RSUs) or the like.

[0055] S120: based on the target closed lane information, issuing a lane change prompt to prompt the driver to change lanes.

[0056] In some examples of the embodiment, the lane change prompt can adopt a prompt mode of text, sound, vibration or light.

[0057] In some embodiments, the target closed lane information further comprises length information of the closed lane, the length information being determined by the cloud server based on the start point position information and the end point position information.

[0058] It can be understood that the cloud server can obtain the length information of the closed lane based on the start position information and the end position information of the closed lane. By obtaining the length information of the closed lane, the vehicle can 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] I. determining a closed lane based on the start position information and / or the end position information.

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

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

[0063] III. If the vehicle is driving 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-mentioned manner, the driver can be prompted to change lanes in a timely manner.

[0065] In some embodiments, if the vehicle is driving 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] I. determining a first distance between the vehicle and the start point of the closed lane.

[0067] II. determining a first time based on the ratio between the first distance and the instantaneous speed of the vehicle.

[0068] III. determining a second time based on the ratio between a preset lane change prompt distance and the instantaneous speed of the vehicle.

[0069] IV. determining a third time based on the sum of the second time and a preset early prompt time.

[0070] V. determining a fourth time based on the difference between the first time and the third time.

[0071] It can be understood that the first time is the time required for the vehicle to travel to the start point of the closed lane at the current instantaneous speed. The second time is the time required for the vehicle to travel from the target position (assuming that the lane change prompt distance is a, and the determination method of the target position is: walking a distance from the start point of the closed lane in the opposite direction of the vehicle travel, and the position reached is the target position) to the start 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) and the like.

[0072] Six, the sum value between the current system time and the fourth time is determined as the lane change prompt time.

[0073] It can be understood that the system time refers to the time of the vehicle system. Through the above-mentioned manner, the preferred time for performing lane change can be obtained, thereby facilitating the driver to perform lane change.

[0074] The mathematical expression for determining the lane change prompt time is: T = localtime + S / V - (S' / V + t), wherein 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 currently set advance prompt time is 10s, the lane change prompt can be issued 10s in advance before the vehicle travels to the start point of the closed lane, thereby facilitating the driver to perform lane change operation. 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 the adaptability is strong.

[0075] Seven, if the vehicle travels 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 the lane to any available lane.

[0076] In some embodiments, if the vehicle travels in the closed lane, a lane change prompt is issued to prompt the driver to change the lane to any available lane, and the method further comprises:

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

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

[0079] It can be understood that in the actual driving process, the vehicle often does not always maintain a uniform speed state, but will appear to change speed, that is, the instantaneous speed of the vehicle and the vehicle position will change constantly. Therefore, based on the changed instantaneous speed of the vehicle and the vehicle position, 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, the lane change prompt can be performed based on the new lane change prompt time, and the accuracy is high.

[0080] In some embodiments, if the vehicle is driving on 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 the lane to any available lane, including:

[0081] I. Obtain the speed signal of the target vehicle driving on the available lane.

[0082] II. If the target vehicle is located behind the vehicle body of the current vehicle, and the speed of the target vehicle is greater than or equal to the speed of the current vehicle, a speed reduction prompt information is issued to prompt the driver to reduce speed, and when the target vehicle drives to the front of the vehicle body of the current vehicle and the distance between the target vehicle and the current vehicle is greater than or equal to a preset distance, the lane change prompt is issued.

[0083] It can be understood that by the above-mentioned manner, the lane change prompt can be issued in time while ensuring the safety of the vehicle.

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

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

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

[0087] II. If the target closed lane information is different from the closed lane notification information, determine the target closed lane information or the closed lane notification information as lane abnormal information based on a preset prompt rule.

[0088] It can be understood that if the target closed lane information is different from the closed lane notification information, it can be caused by communication abnormality between the current vehicle and the cloud server, data transmission failure, communication abnormality between the current vehicle and other vehicles, or other vehicles detecting closed lane information that the cloud server fails to receive. Therefore, the target closed lane information or the closed lane notification information can be determined as lane abnormal information based on a preset prompt rule. The prompt rule can be set according to actual conditions.

[0089] III. Based on the lane abnormal information, the lane change prompt is issued.

[0090] It can be understood that the lane change prompt is issued based on the lane abnormal information, which has high accuracy.

[0091] Figure 2 For an application scenario example of the lane change prompt method provided in an embodiment of the present application, please refer to Figure 2 In the scenarios of road construction or traffic accidents, the first signal generator 210 is arranged at the starting point of the closed lane, and the second signal generator 220 is arranged at the ending point of the closed lane, so that the position information of the closed lane can be uploaded in real time, i.e., 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 ending point position information of the closed lane to the cloud server 230. The cloud server 230 sends the target closed lane information containing the starting point position information and the ending point position information of the closed lane to the vehicle driving on or about to drive on the road where the closed lane is located, so as to facilitate the vehicle to 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 lane except the closed lane in the road where the closed lane is located) and the like. By applying the lane change prompt method in the above embodiment, the vehicle can change lanes in advance, avoiding traffic congestion or traffic accidents and the like.
