With the development of automobiles, the automobiles can interact with the outside based on the automobile wireless communication technology (Vehicle to Everything, V2X), so that the cooperative passing of the automobiles is realized.

Specifically, for any signalless intersection in a road, road network information such as lane information of the intersection, conflict areas in the intersection and the like is acquired, and a plurality of automobiles communicating with the intersection are determined. Since the road-side unit RSU arranged at the intersection can communicate with the on-board units OBU in the vehicles within the sensing range, a plurality of vehicles (i.e. vehicles within the sensing range) can be determined from the road-side unit RSU.

How to determine a plurality of cars to be scheduled is crucial, so in the traffic scheduling method of cars provided in the first embodiment of the present application, in the plurality of cars, the cars are screened according to road network information and car running information of the plurality of cars, and the determining of the plurality of cars to be scheduled includes: determining a lane where the automobile is located according to road network information and vehicle running information of the automobile, and calculating a target distance between the automobile and a lane stop line; determining a regional range according to vehicle running information of the vehicle and a target distance, wherein the regional range represents the regional range of an entrance lane in a plurality of entrance lanes contained in a target intersection; and screening the automobiles in the plurality of automobiles according to the regional range to determine a plurality of automobiles to be scheduled.
Optionally, according to the road network information and the vehicle running information of the vehicle, the lane where the vehicle is located can be determined, and the target distance between the vehicle and the lane stop line is calculated. For example, in the process of screening the automobiles, the vehicles can be matched to corresponding lanes according to real-time longitude and latitude information of the vehicles in road network information and vehicle running information, namely the lanes where the automobiles are located are respectively determined, and the positions of the automobiles, which are away from the lane stop lines, can be obtained by respectively calculating the target distances between the automobiles and the lane stop lines, so that an accurate data basis is provided for the subsequent determination of the regional range.
Optionally, according to the vehicle running information and the target distance of the vehicle, the area range of the entrance lane in the multiple entrance lanes contained in the target intersection can be determined, namely, the statistical distance for counting the vehicle to be scheduled is determined, so that an accurate data basis is provided for screening in multiple vehicles.
Optionally, among the plurality of automobiles, the automobiles are screened according to the regional scope, so that a plurality of automobiles to be scheduled can be determined. For example, the cars in the area range are used as cars to be dispatched, that is, among the cars, the cars in the statistical distance of the entrance lane are screened, that is, the cars in a certain distance from the lane stop line are screened, and a plurality of cars to be dispatched are obtained. For example, vehicles within a distance of 100 meters from the lane stop line are screened out, and a plurality of automobiles to be dispatched are obtained.
By the aid of the process, the automobile to be scheduled is accurately determined, and an accurate data basis is provided for subsequent scheduling processing.
In order to accurately determine a regional scope, in the method for scheduling the passage of an automobile according to the first embodiment of the present application, determining the regional scope according to the vehicle running information and the target distance of the automobile includes: judging whether a first automobile exists in a plurality of lanes contained in an entrance lane according to the vehicle running information of the automobile, wherein the first automobile is an automobile with a lane change behavior; if the first automobile does not exist in the plurality of lanes, taking the first threshold value as the value of the regional range; if a first automobile exists in the plurality of lanes, determining the vehicle position of the first automobile according to the target distance, and determining the regional range according to the vehicle position, the lane solid line length and the first threshold value.
Alternatively, the first car is a car with a lane change behaviour, i.e. a car in which the current lane of the car is not consistent with steering. Specifically, according to the vehicle running information of the vehicle, it may be determined whether the first vehicle exists in a plurality of lanes (for example, a turning lane, a left-turn lane, a straight lane, and a right-turn lane) included in the entrance lane. For example, the lane where the vehicle B is currently located is a straight lane, but if it is known that the travel path of the vehicle B at the target intersection is left turn according to the travel path information in the vehicle running information of the vehicle B, the vehicle B needs to change lanes from the current straight lane to the left turn lane, that is, the vehicle B is the first vehicle with the changed lane.
Optionally, if the first car is not present in the plurality of lanes, the first threshold is taken as the value of the area range. Alternatively, the first threshold may be 100 meters, taking an example that the vehicles in the lanes do not change lanes (i.e. there is no first vehicle), where 100 meters is taken as the value of the area range of the entrance lane, i.e. the area range is a range 100 meters from the lane stop line.
Optionally, if the first car exists in the plurality of lanes, determining a vehicle position of the first car according to the target distance, and determining the regional range according to the vehicle position, the lane solid line length and the first threshold. Specifically, the calculation formula of the statistical distance S1 (i.e., the area range) is as follows:
S1=max (min (S0, 100), solid line length)
Where S0 is the vehicle position of the vehicle where the current lane of the vehicle is inconsistent with the steering and relatively close to the lane stop line, 100 is the first threshold (i.e., 100 meters), and the solid line length is the lane solid line length (typically 40 meters).
For example, there are 5 vehicles on the straight lane, namely, vehicle B, vehicle C, vehicle D, vehicle E and vehicle F, and according to the driving path information of these vehicles, the steering of these vehicles can be known, taking the steering of vehicle B as the left turn, and the other vehicles as the straight turn, then it is determined that vehicle B is the first vehicle with the lane change behavior, then according to the target distance, the positional relationship among vehicle B, vehicle C, vehicle D, vehicle E and vehicle F can be known, namely, according to the distances between these vehicles and the lane stop line, the positional relationship among these vehicles can be known, and according to the distances between vehicle C, vehicle D and vehicle E from the lane stop line is smaller than vehicle B, the distance between vehicle F from the lane stop line is greater than vehicle B, namely, vehicle B is located between vehicle E and vehicle F, at this time, vehicle B is the vehicle where the current lane of which the steering is inconsistent and the distance from the lane stop line is relatively close, namely, the position of vehicle B is S0, and then the regional range is determined according to S0, the length of the solid line and the first threshold (for example, 100 meters).
It should be noted that in the process of determining the area range, by judging whether the first automobile exists in the multiple lanes (namely, the automobile with lane changing behavior) contained in the entrance lane, the lane changing automobile can be filtered, namely, the screened automobile to be scheduled is considered as the automobile without lane changing, so that the situation that the automobile is blocked or the road is jammed at the intersection due to the fact that the intersection is occupied by the wrong lane can be avoided, the automobile can pass more safely, and the passing efficiency of the automobile is remarkably improved.
In order to accurately determine a regional scope, in the method for scheduling the passage of an automobile according to the first embodiment of the present application, determining the regional scope according to a vehicle position, a lane solid line length, and a first threshold value includes: comparing the target distance corresponding to the vehicle position with a first threshold value; if the target distance corresponding to the vehicle position is greater than a first threshold value, taking the value of the first threshold value as the value of the regional range; and if the target distance corresponding to the vehicle position is smaller than or equal to the first threshold value, determining the regional range according to the vehicle position and the length of the lane solid line.
Alternatively, the explanation is continued taking the above-described 5 cars on the straight-traveling lane as an example. In the process of determining the area range according to S0, the length of the lane solid line and the first threshold (100 meters), comparing the target distance (for example, s0=x meters) corresponding to the vehicle position with the first threshold according to the calculation formula of the statistical distance S1, if the target distance corresponding to the vehicle position is greater than the first threshold (i.e., if X > 100), the value of min (S0, 100) is 100, and S1 is 100, i.e., the value of the first threshold is regarded as the value of the area range; if the target distance corresponding to the vehicle position is smaller than or equal to the first threshold value (i.e. if X is smaller than or equal to 100), and the value of min (S0, 100) is S0, the area range needs to be determined continuously according to the vehicle position and the lane solid line length.
In order to accurately determine a regional scope, in the method for scheduling the passage of an automobile according to the first embodiment of the present application, determining the regional scope according to a vehicle position and a lane solid line length includes: comparing the target distance corresponding to the vehicle position with the length of the lane solid line; if the target distance corresponding to the vehicle position is greater than the length of the lane solid line, taking the value of the target distance corresponding to the vehicle position as the value of the area range; and if the target distance corresponding to the vehicle position is smaller than or equal to the length of the lane solid line, taking the value of the length of the lane solid line as the value of the regional range.
Alternatively, the explanation is continued taking the above-described 5 cars on the straight-traveling lane as an example. In the process of determining the area range according to S0 and the lane solid line length, comparing the target distance (for example, s0=x meters) corresponding to the vehicle position with the lane solid line length according to the calculation formula of the statistical distance S1, and if the target distance corresponding to the vehicle position is greater than the lane solid line length (for example, if X > 40), s1=max (X, solid line length) is X, namely, the value of the target distance corresponding to the vehicle position is taken as the value of the area range; if the target distance corresponding to the vehicle position is smaller than or equal to the lane solid line length (i.e., if X is less than or equal to 40), s1=max (X, solid line length) is the lane solid line length, i.e., the value of the lane solid line length is taken as the value of the area range.
By the aid of the process, the area range is accurately determined, so that the automobiles in the area range can be used as automobiles to be scheduled, the automobiles to be scheduled can be accurately determined, further, the situation that the vehicles are blocked or blocked due to the fact that the vehicles occupy wrong lanes at intersections or the vehicles are blocked on roads can be avoided, the vehicles can pass more safely, and the passing efficiency of the vehicles is remarkably improved.
In order to improve the accuracy of traffic scheduling, in the method for traffic scheduling of an automobile provided in the first embodiment of the present application, vehicle operation information and road network information of the automobile to be scheduled are processed to obtain traffic scheduling information of the automobile to be scheduled, including: inputting vehicle running information and road network information of the to-be-scheduled automobile into a target model; and solving the target model to obtain the traffic scheduling information of the automobile to be scheduled.
Optionally, the method provides a no-signal intersection collaborative traffic optimization model (namely a target model) based on that the vehicle delay is smaller than a preset threshold value aiming at the no-signal intersection, and the processing of the vehicle running information and the road network information of the vehicle to be scheduled can be realized by solving the target model, so that the traffic scheduling information of the vehicle to be scheduled is obtained.
Optionally, after the obtained vehicle running information and road network information are represented by data, the vehicle running information and road network information of the vehicle to be scheduled can be input into a target model after the information is converted into the data, and the traffic scheduling information of the vehicle to be scheduled is obtained by solving the target model, so as to obtain the calculation targetAnd representing the positions of the m vehicles (namely a plurality of vehicles to be scheduled) screened at the intersection, which correspond to the n seconds later.
In order to obtain more accurate traffic scheduling information, in the traffic scheduling method of the vehicle provided by the embodiment of the application, a target model is generated by the following method: determining the reference positions of a plurality of automobiles to be scheduled according to the vehicle running information and road network information of the automobiles to be scheduled; determining a target position relation between the automobile to be scheduled and the reference position; and generating a target model according to the reference position and the target position relation.
Optionally, in the process of generating the target model, the acquired vehicle running information and road network information need to be represented by data, that is, a coordinate system origin (i.e., a reference position) is established, and the vehicle running information and the road network information need to be represented according to the origin, so that the information is converted into data.
Optionally, according to the vehicle running information and road network information of the vehicles to be scheduled, the reference positions of the vehicles to be scheduled can be determined. For example, according to the target distance between the vehicle and the lane stop line, which is calculated according to the road network information and the vehicle running information of the vehicle, a vehicle which is relatively far from the lane stop line can be determined from a plurality of vehicles to be dispatched, and the vehicle center of the vehicle which is relatively far from the lane stop line is taken as a reference point, i.e. the vehicle center of the vehicle which is relatively far from the lane stop line is taken as the reference position of the plurality of vehicles to be dispatched.
Alternatively, a process of determining the reference positions of a plurality of automobiles to be scheduled will be described by taking a schematic view of the intersection vehicle positions shown in fig. 4 as an example. As shown in fig. 4, the vehicles 1, 2, 3 and 4 are selected vehicles to be dispatched, and first, a reference point is determined, that is, the vehicle center of the vehicle relatively far from the lane stop line is taken as a reference point (that is, a reference position) for each of the vehicles 1, 2, 3 and 4, that is, the vehicle center of the vehicle 1 is the reference point, the initial position is 0, the vehicle center of the vehicle 4 is the reference point, and the initial position is 0.
Optionally, a target positional relationship between the car to be scheduled and the reference position is determined. Specifically, according to the reference point, the target position (i.e., the initial position) of the screened car to be dispatched is determined, as shown in fig. 4, the vehicle center of the vehicle 1 is the reference point, the initial position is 0, the distance between the vehicle center on the front path and the reference point on the lane is the initial position of the vehicle, that is, the initial position of the vehicle 2 is the distance between the vehicle center of the vehicle 2 and the vehicle center of the vehicle 1 on the lane, that is, the initial position of the vehicle 2 is s2, and the initial position calculation method of the vehicle 3 is consistent with that of the vehicle 2, which is not described herein.
Optionally, the vehicle dynamics information is represented as follows: by x0 i Representing the position corresponding to the initial state of the vehicle i, i.e. the initial position, by v i Indicating the average speed of the vehicle i corresponding to the last second in initial state. Alternatively, the vehicle static information is represented as follows: v max Representing a speed threshold, a, of a vehicle max Representing the addition of vehiclesSpeed threshold, a min Indicating a deceleration threshold value (negative value) of the vehicle, dis f Indicating a safe distance between vehicles, preventing collision.
Optionally, in the process of generating the target model, it is basically assumed that the vehicle cannot change lanes illegally in the solid line range of the entrance lane, and the vehicle can ensure self safety even though related instructions may cause the vehicle to collide, and the vehicle can avoid collision by virtue of self perception and control.
Alternatively, after the acquired vehicle running information is data-represented, the target model may be generated in accordance with the reference position and the target position relationship.
It should be noted that, the target model can be obtained through the above process, so that the vehicle running information and road network information of the vehicle to be scheduled can be processed, and more accurate traffic scheduling information can be obtained.
In order to obtain more accurate traffic scheduling information, in the traffic scheduling method of an automobile provided in the first embodiment of the present application, generating a target model according to a reference position and a target position relationship includes: determining a path fleet position information set, a conflict vehicle information set and a conflict distance information set corresponding to the vehicles to be scheduled according to the reference position and the target position relation, wherein the path fleet position information set is a set of position information in a fleet contained in a driving path of the vehicles to be scheduled when passing through a target intersection, the conflict vehicle information set is a set of vehicle information of the vehicles to be scheduled, which have conflict when passing through the target intersection, of the vehicles to be scheduled, and the conflict distance information set is a set of conflict distance information corresponding to the vehicles to be scheduled, which have conflict; generating a plurality of constraint conditions according to the path fleet position information set, the conflict vehicle information set and the conflict distance information set; and taking the fact that the delay of each of the plurality of automobiles to be scheduled is smaller than a preset threshold value as a first objective function, and generating an objective model according to the first objective function and a plurality of constraint conditions.
Optionally, after the origin (i.e., reference position) of the coordinate system is established, the acquired road network information may be represented as data. Specifically, a route fleet position information set (F), a collision vehicle information set (C), and a collision distance information set (p (i, j), q (i, j)) corresponding to the cars to be scheduled can be determined according to the reference position and the target position relationship. Alternatively, as shown in fig. 4, the vehicles 1, 2, and 3 constitute a vehicle group on the traveling path of the vehicle 1, that is, the vehicle 1 and the vehicles 2, 3 are on the same path through the intersection, and the vehicle 3 is the head vehicle in the traveling direction of the vehicle 1.
Alternatively, taking the schematic diagram of the intersection vehicle position shown in fig. 4 as an example, the road network information is represented as follows:
path fleet location information set (F): and (3) recording (i, j) when the vehicle i and the vehicle j are on the same path passing through the intersection and the vehicle i is the head vehicle in the running direction of the vehicle j, wherein the set of the position information of the vehicle in the corresponding path motorcade. For example, (3, 2), (2, 1) shown in fig. 4 should be contained in F.
Conflict vehicle information set (C): recording the vehicle pairs with conflict points on the paths of the two vehicles passing through the intersection. For example, (4, 3), (4, 2), (4, 1) shown in fig. 4 should be included in C.
p (i, j): for the conflicting vehicle pair (i, j) in C, the distance between the central point of the conflicting area corresponding to the vehicle i and the path of the corresponding datum point of the vehicle i is recorded. As shown in fig. 4, p (1, 4), p (2, 4), p (3, 4) in the respective vehicles 1 and 4, 2 and 4, 3 and 4 are distances on the paths of the respective collision areas and the reference point (i.e., the vehicle center of the vehicle 1) in the figure.
q (i, j): for the conflicting vehicle pair (i, j) in C, the distance on the path where the center point of the conflicting region corresponding to vehicle i and vehicle j is located from the corresponding reference point of vehicle j is recorded. As shown in fig. 4, q (1, 4), q (2, 4), q (3, 4) and q (3, 4) corresponding to the vehicles 1 and 4, 2 and 4, and 3 and 4 are all distances on the paths corresponding to the collision areas and the reference points (i.e., the vehicle centers of the vehicles 4) in the figure.
Optionally, according to the path fleet location information set, the conflict vehicle information set and the conflict distance information set, a plurality of constraint conditions may be generated, and the target model is generated according to the first target function and the constraint conditions by taking a fact that a vehicle delay of a plurality of vehicles to be scheduled is smaller than a preset threshold as the first target function. Optionally, the constraint conditions of the target model include a travel speed constraint, an acceleration constraint, an inter-vehicle safe distance constraint, and a vehicle collision limit constraint.
For example, byAnd representing the positions of m vehicles (namely a plurality of vehicles to be scheduled) screened at the intersection, which correspond to each other after the nth second, as calculation targets. Taking the fact that the delay of each of the plurality of automobiles to be scheduled is smaller than a preset threshold value as a first objective function, namely summing the positions of the plurality of automobiles to be scheduled in n seconds, and hopefully, the sum is as large as possible. For example, after n seconds, if the travel distance of a plurality of cars to be scheduled is as large as possible, the average delay of the cars is as small as possible, thereby achieving faster passage of the cars through the intersection. Specifically, the first objective function is as follows: />
Specifically, the established optimization model (i.e., the target model) is as follows:
optionally, the object model contains constraints (1) to (8). Wherein conditions (1) and (2) represent that the vehicle speed per second is limited by a speed threshold; conditions (3) to (5) represent that the vehicle acceleration is limited by an acceleration threshold value and a deceleration threshold value; condition (6) represents a safe distance limit between vehicles in front and behind the same lane; conditions (7) and (8) indicate that collision avoidance limits, i.e. two vehicles on the path that have a collision, need to maintain a safe distance through the collision point.
It should be noted that, in the scheme, aiming at the vehicles (i.e. the vehicles to be scheduled) within a certain range of the entrance lane of the current intersection, the whole process that the vehicles enter the exit lane through the intersection is considered, an optimization model is established according to constraint conditions so as to solve a global optimal solution, and compared with a first-to-first-walk model, unnecessary delay is reduced, and the vehicle passing efficiency is improved; compared with a single vehicle track planning model, the method and the device have the advantages that the traffic scheduling processing is carried out according to the vehicle information and the road network information of the whole intersection, more accurate traffic scheduling information can be obtained, and the accuracy of traffic scheduling is remarkably improved.
In order to obtain more accurate traffic scheduling information, in the traffic scheduling method of an automobile provided in the first embodiment of the present application, a target model is solved to obtain traffic scheduling information of an automobile to be scheduled, including: solving the target model according to linear constraint conditions in the constraint conditions to obtain an initial solution of the target model; generating a second objective function according to the nonlinear constraint condition in the constraint conditions and the first objective function; and solving the target model according to the initial solution and the second target function to obtain the traffic scheduling information of the automobile to be scheduled.
Optionally, the scheme provides a signal-free intersection collaborative traffic optimization model aiming at vehicles (namely vehicles to be scheduled) within a certain range of an entrance lane of a current intersection, and aims at that the vehicle delay of a plurality of vehicles to be scheduled is smaller than a preset threshold value, and provides a feasible solving method.
Alternatively, since conditions (7) and (8) are non-convex and cannot be directly solved using a solver, the model is classified into models that can be solved by an existing solver according to the vehicle's own safety guarantee setting in the basic assumption. For example, the target model is solved according to a linear constraint condition in the constraint conditions, and an initial solution of the target model is obtained. Considering only the constraints (1) to (6), the model is a linear programming model (i.e. an initial solution model), alternatively, the initial solution can be obtained as an initial value of the solution model by solving the model with an existing solver.
Optionally, the second objective function is generated from the first objective function and a nonlinear constraint in the plurality of constraints. For example, by transforming the nonlinear constraints (7) and (8) onto the first objective function, a second objective function may be generated as follows:
wherein:
optionally, according to the initial solution and the second objective function, solving the objective model (i.e. solving the model), thereby obtaining the traffic scheduling information of the car to be scheduled. For example, according to the initial solution and the second objective function, only the constraint conditions (1) to (6) are considered, and the model can be iteratively solved by the existing solver to obtain the calculation objective
In order to improve the accuracy of traffic scheduling for vehicles, in the traffic scheduling method for vehicles provided in the first embodiment of the present application, according to traffic scheduling information of vehicles to be scheduled, the scheduling processing for the vehicles to be scheduled includes: determining the target running speed and the target running acceleration of the automobile to be scheduled according to the traffic scheduling information of the automobile to be scheduled; generating a target control instruction according to the target running speed and the target running acceleration, and respectively issuing the target control instruction to the automobile to be scheduled based on the preset time length so as to control the automobile to be scheduled to run according to the target running speed and the target running acceleration.
Optionally, the vehicle to be scheduled is a vehicle to which a control instruction is to be issued, the traffic scheduling information is second driving position information of the vehicle, and the target driving of the vehicle to be scheduled can be determined according to the traffic scheduling information of the vehicle to be scheduledSpeed and target travel acceleration. For example, a solution obtained from the above model (i.e) The vehicle positions corresponding to m vehicles (namely a plurality of vehicles to be scheduled) screened at the intersection after the nth second can be known, and the target running speed and the target running acceleration can be calculated based on the adjacent position information. For example, the traffic scheduling information of the vehicle a is 1 st second to the position 1 and 2 nd second to the position 2, and based on these information, the corresponding running speed and running acceleration can be calculated, so that the scheduling of the vehicle a can be realized based on the running speed and the running acceleration.
Optionally, generating a target control instruction according to the target running speed and the target running acceleration, and respectively issuing the target control instruction to the automobile to be scheduled based on the preset duration so as to control the automobile to be scheduled to run according to the target running speed and the target running acceleration. For example, after the target control command is generated, the running speed and the running acceleration are issued to the vehicle in seconds, so that the vehicle to be scheduled runs according to the issued running speed and running acceleration, and the traffic scheduling of the vehicle to be scheduled is realized.
