Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of intelligent vehicles, in particular relates to a method, system, medium and first vehicle for recommending a driving lane for a vehicle. BACKGROUND

[0002] When a vehicle is driving on a road, the following problems often occur when the vehicle drives to a traffic light intersection with both straight lanes and right-turn-plus-straight lanes:

[0003] (1) On the right-turn-plus-straight lane, vehicles that are going to turn right cannot pass through because there are many straight vehicles waiting for the traffic light in front, and the vehicles that are going to turn right can only pass through after the straight vehicles in front pass through when the traffic light turns green, thereby causing unnecessary waiting for the vehicles that are going to turn right.

[0004] (2) On the straight lane, there are many straight vehicles waiting for the traffic light, while there are no vehicles on the right-turn-plus-straight lane, which causes unnecessary waiting for the vehicles that are going to straight on the straight lane.

[0005] Therefore, how to provide a method for recommending a driving lane for a vehicle to solve the above technical problems has become a technical problem to be solved by technical personnel in the field. SUMMARY

[0006] In view of the above-mentioned shortcomings of the prior art, the purpose of the present application is to provide a method, system, medium and first vehicle for recommending a driving lane for a vehicle, which is used to solve the problem that a vehicle driving to a traffic light intersection is prone to unnecessary waiting, thereby bringing an uncomfortable driving experience to the user.

[0007] Another purpose of the present application is to provide a method, system, medium and first vehicle for recommending a driving lane for a vehicle, which actively recommends a driving lane for the vehicle based on the right-turn-waiting information of the vehicle behind the vehicle when the vehicle drives to a traffic light intersection, effectively solves the problem that the vehicle (including the vehicle behind the vehicle) is prone to more unnecessary waiting at the traffic light intersection, brings a good driving experience to the user, ensures the smoothness of the vehicle driving, and further reduces the possibility of traffic congestion at the traffic light intersection.

[0008] Still another purpose of the present application is to provide a method, system, medium and first vehicle for recommending a driving lane for a vehicle, which, when recommending a driving lane for the first vehicle based on the right-turn-waiting information of the second vehicle behind the first vehicle, first determines whether the first vehicle can change lanes, if the first vehicle cannot change lanes, the first vehicle can only continue to wait for the traffic light on its current driving lane, and only when the first vehicle can change lanes, the subsequent recommendation of the driving lane is further executed.

[0009] Still another object of the present application is to provide a method, system, medium and first vehicle for recommending a driving lane for a vehicle, when receiving a right-turn waiting information, by comparing the number of vehicles waiting for a red light on a straight lane and the number of vehicles waiting for a red light on a right-turn-and-straight lane, to recommend a driving lane, so as to avoid the situation that the number of vehicles waiting for a red light on the straight lane is less than the number of vehicles waiting for a red light on the right-turn-and-straight lane, and the first vehicle is parked on the right-turn-and-straight lane to wait for a red light, on the one hand, the time for the first vehicle to wait for a red light is shortened; on the other hand, the problem that the right-turn vehicle on the right-turn-and-straight lane cannot pass through because there are many straight vehicles waiting for a red light in front of the right-turn vehicle until the straight vehicles pass through after the green light is on, and the right-turn vehicle has to wait unnecessarily is effectively solved.

[0010] Still another object of the present application is to provide a method, system, medium and first vehicle for recommending a driving lane for a vehicle, when the number of vehicles waiting for a red light on a straight lane is greater than the number of vehicles waiting for a red light on a right-turn-and-straight lane, by considering the number of vehicles waiting for a red light on the right-turn-and-straight lane, judging whether the number of vehicles waiting for a red light on the right-turn-and-straight lane is less than a first preset threshold, and recommending the first vehicle to wait for a red light on the right-turn-and-straight lane when the number of vehicles waiting for a red light on the right-turn-and-straight lane is less than the first preset threshold, so as to avoid the situation that there are many straight vehicles waiting for a red light on the straight lane, and the number of vehicles waiting for a red light on the right-turn-and-straight lane is less, and the first vehicle is parked on the straight lane to wait for a red light, thereby reducing unnecessary waiting of the straight vehicle behind the first vehicle.

[0012] Still another object of the present application is to provide a method, system, medium and first vehicle for recommending a driving lane for a vehicle, when not receiving a right-turn waiting information, by comparing the number of vehicles waiting for a red light on a straight lane and the number of vehicles waiting for a red light on a right-turn-and-straight lane, to recommend a driving lane, so as to improve the flexibility of vehicle driving, further improve the smoothness of road driving, and effectively reduce the possibility of traffic congestion at a red light intersection.

[0013] Still another object of the present application is to provide a method, system, medium and first vehicle for recommending a driving lane, which judges whether a vehicle can pass a traffic light intersection by combining the current speed of the vehicle, the distance between the current position of the vehicle and the start and end lines of the traffic light, and the remaining time of the green light, so that the vehicle is more automated and intelligent, and the safety and reliability of vehicle driving are improved.

[0048] Other advantages and effects of the present application can be easily understood by those skilled in the art from the above description. The present application can also be implemented or applied in other different embodiments, and various modifications or changes can be made to the details of the present application 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.

[0049] It should be noted that the diagrams provided in the following embodiments only schematically illustrate the basic concept of the present application, 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 shape, number and ratio of each component when actually implemented can be arbitrarily changed, and the layout of the components can be more complex.

[0050] The method, system and medium for recommending a driving lane for a vehicle of the present application actively recommend a driving lane for the vehicle based on the right-turn-waiting information of the vehicle behind the vehicle when the vehicle drives to a traffic light intersection, effectively solve the problem of unnecessary waiting of the vehicle (including the vehicle behind the vehicle) at the traffic light intersection, bring good driving experience to the user, ensure the smoothness of vehicle driving, and further reduce the possibility of traffic congestion at the traffic light intersection. The present application recommends a driving lane for the vehicle based on the right-turn-waiting information of the vehicle behind the vehicle, in combination with the number of vehicles waiting for the traffic light on the straight lane and the right-turn-and-straight lane, and the number of right-turn-waiting vehicles behind the vehicle, to ensure the reliability of the recommended driving lane.

[0051] As shown in Figure 2 , in an embodiment, the method for recommending a driving lane for a vehicle of the present application is applied to a vehicle terminal (not shown in Figure 2 ) for recommending a driving lane for a front vehicle 21 (corresponding to the first vehicle in the present application) in Figure 2 ; wherein the vehicle terminal is arranged in the front vehicle 21; specifically, the working principle of the method for recommending a driving lane for a vehicle is as follows:

[0052] When the front vehicle 21 drives, a traffic light intersection in front is recognized (such as Figure 2As shown, when the front vehicle 21 is straight at the traffic light intersection (the front vehicle 21 is straight at the traffic light intersection), first, the vehicle terminal determines whether the front vehicle 21 can pass through the traffic light intersection; if so, the vehicle terminal prompts the owner to pass through the traffic light intersection normally; otherwise, if not (at this time, there is a rear vehicle 22 (corresponding to the second vehicle in the present application) behind the front vehicle 21, and the rear vehicle 22 wants to turn right, the rear vehicle 22 will send the corresponding right-turn information to the front vehicle 21), the vehicle terminal will respond to the right-turn information sent by the rear vehicle 22 in the Figure 2

[0053] Specifically, when the rear vehicle 22 identifies the traffic light intersection in front of it during driving, the rear vehicle 22 generates right-turn information and sends the right-turn information to the V2X base station 23 in the Figure 2 Figure 2 After receiving the right-turn information, the V2X base station 23 sends the right-turn information to the front vehicle 21.

[0054] It should be noted that the V2X base station 23 described above is not a necessary structure, that is, the right-turn information generated by the rear vehicle 22 can also be sent to the front vehicle 21 by other means.

[0055] As shown in Figure 3 , in an embodiment, the vehicle recommended driving lane method of the present application is applied to a first vehicle; specifically, the vehicle recommended driving lane method comprises the following steps:

[0056] Step S1, in the case of identifying that the vehicle is in front of a traffic light intersection, determining whether the first vehicle can pass through the traffic light intersection.

[0057] It should be noted that the traffic light intersection at least includes but is not limited to a straight lane and a right-turn plus straight lane, such as a left-turn lane, a left-turn plus U-turn lane; the first vehicle is straight at the traffic light intersection.

[0058] In an embodiment, based on the real-time positioning information of the first vehicle, it is identified whether there is a traffic light intersection in the front direction of the first vehicle; when a traffic light intersection is identified, the real-time distance between the current position of the first vehicle and the traffic light intersection can also be determined.

[0059] Specifically, the first vehicle sends its real-time positioning information to the cloud, so that the cloud determines whether there is a traffic light intersection in the front direction of the first vehicle based on the real-time positioning information and road information.

[0060] ​​​It is to be noted that the road information is stored in the cloud, and the road information includes but is not limited to: the position information of the traffic light in the road, and the lane information of the traffic light intersection.

[0061] In an embodiment, whether there is a traffic light intersection in the advancing direction of the first vehicle is identified by a camera installed on the first vehicle.

[0062] Specifically, the camera collects images in front of the vehicle in real time, and sends the images to the vehicle terminal of the first vehicle, so that the vehicle terminal determines whether there is a traffic light intersection in the advancing direction of the first vehicle.

[0063] It is to be noted that considering the limited image collection range of the camera, this embodiment will also be limited in actual application.

[0064] Further, how to identify whether there is a traffic light intersection in the advancing direction of the vehicle is not a condition for limiting the present application, and the above two embodiments are only two different embodiments, and in actual application, a suitable identification method can be selected according to the specific application scene.

[0065] Specifically, when it is identified that there is a traffic light intersection in the advancing direction of the first vehicle, the first vehicle determines whether it can pass through the traffic light intersection smoothly.

[0066] In an embodiment, the determination of whether the first vehicle can pass through the traffic light intersection includes the following steps: based on the current speed of the first vehicle, the distance between the current position of the first vehicle and the start-stop line of the traffic light, and the remaining time of the green light, it is determined whether the first vehicle can pass through the traffic light intersection.

[0067] It is to be noted that the intelligent vehicle can identify the state of the traffic light, and determine whether the vehicle can pass through the traffic light according to the vehicle speed, the remaining time of the green light, the distance between the vehicle and the start-stop line of the traffic light, and the like, so the working principle of how to determine whether the first vehicle can pass through the traffic light is not described in detail here.

[0068] It is to be noted that in this embodiment, whether the vehicle can pass through the traffic light intersection is determined by combining the current speed of the vehicle, the distance between the current position of the vehicle and the start-stop line of the traffic light, and the remaining time of the green light, so that the vehicle is more automated and intelligent, and the safety and reliability of vehicle driving is improved.

[0069] Further, in addition to considering the current speed of the first vehicle, the distance between the current position of the first vehicle and the start-stop line of the traffic light, and the remaining time of the green light, the number of vehicles waiting for the traffic light on the straight lane and the right-turn plus straight lane is also considered to comprehensively determine whether the first vehicle can pass through the traffic light intersection.

[0070] If yes, step S2 is performed; otherwise, steps S3-S5 are performed.

[0071] Step S2, prompting the first vehicle to pass through the traffic light intersection.

[0072] Specifically, when it is determined through step S1 that the first vehicle can pass through the traffic light intersection smoothly, a prompt is given to enable the user to directly drive the first vehicle through the traffic light intersection based on the prompt.

[0073] It should be noted that the specific manner in which the vehicle terminal gives the prompt does not limit the present application, such as, a voice prompt can be used, or a light prompt can be used, etc., and in actual applications, a corresponding prompt manner can be selected according to a specific application scenario.

[0074] Further, when it is determined through step S1 that the first vehicle cannot pass through the traffic light intersection, the advancing directions of the vehicles behind the first vehicle at the traffic light intersection need to be considered; specifically, if there is a vehicle that intends to turn right at the traffic light intersection among the vehicles behind the first vehicle, step S3 is correspondingly performed; if none of the vehicles behind the first vehicle intends to turn right at the traffic light intersection, steps S4 and S5 are correspondingly performed.

[0075] Step S3, recommending a driving lane in response to receiving the right-turn-waiting information of the second vehicle.

[0076] It should be noted that the second vehicle is located behind the first vehicle.

[0077] Specifically, when there is a second vehicle behind the first vehicle and the advancing direction of the second vehicle at the traffic light intersection is right turn, the second vehicle will send right-turn-waiting information to the first vehicle, and the first vehicle will receive the right-turn-waiting information; specifically, the vehicle terminal of the first vehicle receives the right-turn-waiting information and recommends a driving lane based on the right-turn-waiting information.

[0078] It should be noted that the second vehicle will also identify whether there is a traffic light intersection in its advancing direction during driving, just like the first vehicle described above (the specific identification method is described above and will not be repeated here), and when it is identified that there is a traffic light intersection, the second vehicle will send its right-turn-waiting information to the first vehicle.

[0079] In an embodiment, the second vehicle sends the right-turn-waiting information to the first vehicle through V2X.

[0080] Specifically, the second vehicle first sends the right-turn-waiting information to a V2X base station, and then sends the right-turn-waiting information to the first vehicle in a broadcast or unicast manner after the V2X base station receives the right-turn-waiting information.

[0081] It should be noted that the right-turn information of the second vehicle is not limited to being sent to the first vehicle through the V2X base station, such as the second vehicle can first send the right-turn information to the cloud, and then the cloud sends the right-turn information to the first vehicle.

[0082] It should be noted that when the vehicle drives to the traffic light intersection, based on the right-turn information of the vehicle behind the vehicle, the vehicle is actively recommended to drive the lane, effectively solving the problem of unnecessary waiting of the vehicle (including the vehicle behind the vehicle) at the traffic light intersection, bringing good driving experience to the user, ensuring the smoothness of vehicle driving, and further reducing the possibility of traffic congestion at the traffic light intersection.

[0083] As shown in Figure 4 In an embodiment, the recommended driving lane includes the following steps:

[0084] Step S31, determine whether the current position allows lane changing.

[0085] Specifically, according to the current position of the first vehicle, it is determined whether it can change lanes.

[0086] It should be noted that the vehicle can change lanes at the dashed line of the road, and cannot change lanes when driving to the solid line of the road.

[0087] In an embodiment, a camera provided on the first vehicle is used to collect a road image, and the road image is sent to the vehicle terminal of the first vehicle, so that the vehicle terminal identifies the road image. If a dashed line is identified, the first vehicle is allowed to change lanes at the current position; otherwise, if a solid line is identified, the first vehicle is not allowed to change lanes at the current position.

[0088] Further, when determining whether the first vehicle is allowed to change lanes at the current position in step S31, in addition to considering the solid line and the dashed line on the road, the distance between the vehicle behind the current driving lane of the first vehicle and the first vehicle also needs to be considered. Whether the first vehicle is allowed to change lanes at the current position is determined by considering a variety of factors, which ensures the safety of the first vehicle changing lanes and greatly reduces the possibility of traffic accidents caused by lane changing.

[0089] If not, step S32 is performed; otherwise, if allowed, step S33 is performed.

[0090] Step S32, recommend the first vehicle to wait for a traffic light in the current driving lane.

[0091] Step S33, recommend a driving lane according to the number of vehicles waiting for a traffic light on the straight lane and the number of vehicles waiting for a traffic light on the right-turn and straight lane.

[0092] In one embodiment, a camera installed on the first vehicle captures an image in front of the first vehicle and sends the image to the on-board terminal of the first vehicle, so that the on-board terminal can determine the number of vehicles waiting for the traffic light in the through lane and the number of vehicles waiting for the traffic light in the right turn and through lane by identifying the image.

[0093] In one embodiment, a real-time image of the traffic light intersection is collected by a road camera at the traffic light intersection, and the real-time image is uploaded to the cloud, so that the cloud can determine the number of vehicles waiting for the traffic light in the through lane and the number of vehicles waiting for the traffic light in the right turn and through lane by identifying the real-time image; then, the determined number of vehicles waiting for the traffic light in the through lane and the number of vehicles waiting for the traffic light in the right turn and through lane are sent to the first vehicle through the cloud, so that the first vehicle executes the above-mentioned step S33.

[0094] It should be noted that when recommending a driving lane for the first vehicle based on the right-turn information of the second vehicle behind the first vehicle, it is first determined whether the first vehicle can change lanes at present. If not, the first vehicle can only continue to wait for the traffic light in its current driving lane. Only when it can change lanes will the subsequent recommended driving lane be further executed.

[0095] like Figure 4 As shown, in one embodiment, the recommended driving lane according to the number of vehicles waiting for the traffic light on the through lane and the number of vehicles waiting for the traffic light on the right turn and through lane includes the following steps:

[0096] Step S331: When the number of vehicles waiting for the traffic light on the through lane is not greater than the number of vehicles waiting for the traffic light on the right-turn and through lane, it is recommended that the first vehicle wait for the traffic light in the through lane.

[0097] Step S332: When the number of vehicles waiting for the traffic light on the through lane is greater than the number of vehicles waiting for the traffic light on the right-turn and through lane, a driving lane is recommended based on the number of vehicles waiting for the traffic light on the right-turn and through lane.

[0098] It should be noted that when the right-turn waiting information is received, the driving lane is recommended by comparing the number of vehicles waiting for the red light on the straight lane and the number of vehicles waiting for the red light on the right-turn and straight lane, so as to avoid the case that the number of vehicles waiting for the red light on the right-turn and straight lane is less than the number of vehicles waiting for the red light on the straight lane, and the first vehicle stops on the right-turn and straight lane to wait for the red light. On the one hand, the waiting time of the first vehicle for the red light is shortened. On the other hand, the problem that the right-turn vehicle on the right-turn and straight lane cannot pass through because there are many straight vehicles waiting for the red light in front until the green light is on and the straight vehicles in front pass through is effectively solved, so that unnecessary waiting of the right-turn vehicle is avoided.

[0099] As shown in Figure 5 in an embodiment, the driving lane is recommended according to the number of vehicles waiting for the red light on the right-turn and straight lane, which includes the following steps:

[0100] Step S3321, determining whether the number of vehicles waiting for the red light on the right-turn and straight lane is less than a first preset threshold.

[0101] In an embodiment, based on the number of vehicles waiting for the red light on the right-turn and straight lane determined above, it is determined whether the number of vehicles waiting for the red light on the right-turn and straight lane is less than the first preset threshold.

[0102] It should be noted that the first preset threshold is a threshold set in advance, and the specific value is not limited to the present application. In actual application, the threshold can be set according to the specific application scene, so it will not be described in detail here.

[0103] If it is less than, step S3322 is performed; otherwise, if it is not less than, step S3323 is performed.

[0104] Step S3322, recommending the first vehicle to wait for the red light on the right-turn and straight lane.

[0105] Step S3323, recommending the driving lane in combination with the right-turn waiting information.

[0106] It should be noted that when the number of vehicles waiting for the red light on the straight lane is greater than the number of vehicles waiting for the red light on the right-turn and straight lane, the number of vehicles waiting for the red light on the right-turn and straight lane is considered, and it is determined whether the number of vehicles waiting for the red light on the right-turn and straight lane is less than a first preset threshold, so that when the number of vehicles waiting for the red light on the right-turn and straight lane is less than the first preset threshold, the first vehicle is recommended to wait for the red light on the right-turn and straight lane, so as to avoid the case that there are many straight vehicles waiting for the red light on the straight lane, while the number of vehicles waiting for the red light on the right-turn and straight lane is less, and the first vehicle stops on the straight lane to wait for the red light, thereby reducing unnecessary waiting of the rear vehicle on the straight lane waiting for straight.

[0107] like Figure 5 As shown, in one embodiment, the recommending a driving lane in combination with the pending right turn information includes the following steps:

[0108] Step S33231: Determine whether the number of the pending right turn information is less than a second preset threshold.

[0109] Specifically, based on the pending right turn information received by the vehicle-mounted terminal in step S3, the number of the pending right turn information is determined to determine whether it is less than the second preset threshold.

[0110] It should be noted that one waiting-to-turn-right information corresponds to one second vehicle waiting to turn right, and the number of the waiting-to-turn-right information is the number of the second vehicles.

[0111] It should be noted that the second preset threshold is a pre-set threshold, and its specific setting is not a condition to limit the present invention. In actual application, it can be set according to the specific application scenario, so it will not be described in detail here.

[0112] If it is not less than, execute step S33232; otherwise, if it is less than, execute step S33233.

[0113] Step S33232: Recommend the first vehicle to wait for the traffic light in the through lane.

[0114] Step S33233: recommend that the first vehicle wait for the traffic light in the right-turn and through lane.

[0115] It should be noted that when the number of vehicles waiting for the traffic light in the through lane is greater than the number of vehicles waiting for the traffic light in the right turn and through lane, and the number of vehicles waiting for the traffic light in the right turn and through lane is not less than a first preset threshold, the number of second vehicles waiting to turn right behind the first vehicle is considered, and by judging whether it is less than a second preset threshold, it is recommended to wait for the traffic light in the through lane or in the right turn and through lane based on the judgment result, thereby improving the reliability of the recommended driving lane and bringing a better driving experience to users.

[0116] Furthermore, after recommending a driving lane for the first vehicle, corresponding feedback information is sent to the second vehicle.

[0117] It should be noted that the specific content of the feedback information is not a condition for limiting the present invention. In actual application, the specific content of the feedback information can be sent to the second vehicle according to needs.

[0118] It should be noted that, on the one hand, the feedback information is used to inform the second vehicle that the first vehicle has received the right turn information sent by it; on the other hand, it enables the second vehicle to know the driving lane recommended by the first vehicle in advance based on the feedback information.

[0119] Step S4: In response to not receiving the waiting right turn information, obtaining the number of vehicles waiting for the traffic light on the right-turn plus through lane and the number of vehicles waiting for the traffic light on the through lane.

[0120] Specifically, in step S4, the number of vehicles waiting for the traffic light on the right-turn and through lane and the number of vehicles waiting for the traffic light on the through lane can be obtained by referring to the specific discussion on the working principle of step S33 above, so it will not be repeated here.

[0121] Step S5: recommend a driving lane based on the number of vehicles waiting for the traffic light on the right-turn and through lane and the number of vehicles waiting for the traffic light on the through lane.

[0122] In one embodiment, the recommended driving lane according to the number of vehicles waiting for the traffic light in the right-turn and through lane and the number of vehicles waiting for the traffic light in the through lane includes the following situations:

[0123] (1) When the number of vehicles waiting for the traffic light on the right-turn and through lane is greater than the number of vehicles waiting for the traffic light on the through lane, it is recommended that the first vehicle wait for the traffic light on the through lane.

[0124] (2) When the number of vehicles waiting for the traffic light on the right-turn and through lane is less than the number of vehicles waiting for the traffic light on the through lane, it is recommended that the first vehicle wait for the traffic light on the right-turn and through lane.

[0125] (3) When the number of vehicles waiting for the traffic light on the right-turn and through lane is equal to the number of vehicles waiting for the traffic light on the through lane, it is recommended that the first vehicle wait for the traffic light on the through lane or on the right-turn and through lane.
