In order to solve the drawbacks of the prior art, the present invention provides a fleet management method, apparatus, system, electronic device, and storage medium, which can effectively reduce the waiting time of the transportation demander and help the driver of the vehicle to know the transportation route.
Referring initially to fig. 1, fig. 1 illustrates a flow diagram of a fleet management method according to an embodiment of the present invention. Specifically, in various embodiments of the present invention, a fleet of vehicles includes at least a command vehicle that stops one or more intermediate sites during travel to a destination site.
Fig. 1 shows a total of five steps:
step S110: before the command vehicle stops at an intermediate station, determining the bearing demand of a bearing object of the intermediate station;
step S120: the command vehicle judges whether the carrying residual capacity of the motorcade where the command vehicle is located at the intermediate site is greater than or equal to the carrying demand;
if not, step S130: the command car broadcasts request information requesting a support vehicle through V2V;
step S140: when the commander vehicle receives support determination information returned by the support vehicle through V2V, the commander vehicle transmits driving data to the support vehicle through V2V to join the support vehicle as a slave vehicle to the fleet;
step S150: and the command vehicle controls the fleet to stop at the intermediate station, bear the bearing object of the intermediate station and drive to the next intermediate station.
In various embodiments of the present invention, after step S150, steps S110 through S150 are performed cyclically through each intermediate site until the fleet travels to the destination site.
In the fleet management method provided by the invention, when the remaining bearing capacity of the fleet where the command vehicle is located at the intermediate site is less than the bearing demand, a support request is sent by using the internet of vehicles technology, so that the adjacent vehicles can be used as slave vehicles to join the fleet after receiving the request, and the fleet management is carried out through the command vehicle, therefore, a dispatching center is not required to dispatch the vehicles, and the waiting time of a demander is effectively reduced; meanwhile, the command vehicle enables the slave vehicle to follow the command vehicle to run through the sharing of the running data, and a driver of the slave vehicle does not need to be familiar with a transportation route.
In various embodiments of the present invention, the command vehicle communicates with other vehicles or other devices via the Internet of vehicles. The car networking is a network for connecting cars, is a mobile phone and is used for processing information of each car in a road traffic network and realizing information sharing, so that a person-car-road three-in-one internet is realized. Specifically, the command Vehicle in the invention communicates with other vehicles through a Vehicle to Vehicle (V2V) technology in the internet of vehicles, so as to realize the fleet management of the command Vehicle to the slave vehicles.
In the fleet management, a tighter connection mode is provided for vehicles in the fleet, and the fleet can share information in time, so that the safety is provided, the fuel cost can be reduced, and the running efficiency of the fleet is improved. In one implementation of fleet management, director vehicle a and slave vehicle B, C, D are located on the same road and travel in the same direction (director vehicle a and slave vehicle B, C, D are for clarity of description only, in the present invention, a fleet of vehicles may include only director vehicle a during travel to a destination site, and the number of slave vehicles varies with the load carrying demand at each intermediate site). The director vehicle a and the slave vehicle B, C, D share the surrounding timely traffic and road information through fleet management, and the director vehicle a may report all information to and receive traffic and road information from road side devices (RSUs). The director car a may share the traffic and road information received from the roadside apparatus to the slave car B, C, D so that the travel path may be updated in real time so that the director car a and the slave car B, C, D may travel to the destination station along the same travel path.
Further, basic information is continuously exchanged between the director car a and the slave car B, C, D within the communication range. The basic information can be divided into important information (having a fast update rate), secondary information (having a slow update rate), and supplementary information. Important information may include, for example: speed, driving direction, vehicle length, longitudinal acceleration, curvature calculation mode, yaw rate, acceleration, lane position, steering wheel angle, lateral acceleration, vertical acceleration, and the like. The secondary information may include: vehicle usage (passenger transport, freight transport), vehicle signal light information, historical route, etc. The supplementary information may include: special transportation (overweight, vehicle width greater than standard width, vehicle length greater than standard vehicle length, etc.), transportation of harmful substances, road engineering (road repairing, snow shoveling, etc.), rescue operations (ambulances, police cars, fire trucks), etc. The commander Vehicle a transmits traveling data (similar to DENM distributed environment notification information format specified by ETSI european telecommunications standardization institute) to the slave Vehicle B, C, D, and the slave Vehicle B, C, D receives the traveling data via V2X (V2V (Vehicle to Vehicle), V2I (Vehicle to Infrastructure), and V2N (Vehicle to Network), thereby traveling in accordance with the speed, steering information, and the like of the commander Vehicle a. In each embodiment of the invention, the slave vehicle can follow the command vehicle A to run in the above fleet management mode.
In various embodiments of the present invention, the load-bearing object may be, for example, a passenger or a cargo, which is not limited to the embodiments.
In a specific embodiment of the present invention, the step S110 of determining the carrying demand of the carrying object at the intermediate station before the vehicle is directed to stop at the intermediate station may further include the following steps:
the command car receives bearing information of the bearing object, wherein the bearing information comprises bearing capacity of the bearing object, a starting place of the bearing object and a destination of the bearing object, the starting place of the bearing object is any station intermediate station, and the destination of the bearing object is any station intermediate station or destination station behind the starting place;
and the command vehicle takes the sum of the bearing capacity of the bearing objects at the same starting place as the bearing demand of the intermediate station corresponding to the same starting place.
In particular, the bearer information of the bearer object of each intermediate site may be sent to the command car before the fleet travels to the intermediate site. In other embodiments, the bearer information for the bearer object at each intermediate site may be sent to the command car before the fleet begins traveling. In the former embodiment, the carrying objects are not limited to send the carrying information before the motorcade runs, so that each carrying object has more flexible sending time of the carrying information. In the latter embodiment, it is convenient for the command vehicle to know the load-bearing condition of the whole transportation route in advance, so that the command vehicle can broadcast the request information of the request support vehicle as early as possible, thereby improving the probability of the support vehicle joining the fleet.
Further, in some embodiments, the bearer object may send bearer information, for example, via user terminal 25 (fig. 4). In other embodiments, the bearer object may send the bearer information, for example, via a site device provided by the intermediate site 22. The invention is not limited thereto.
Specifically, referring to fig. 2, the car commander 21 receives the bearer information transmitted from each bearer object (passenger 23) at the intermediate station 22. In the carrying information sent by the passenger 23, the carrying capacity of the carrying object is 1 person (when the carrying object is a cargo, the carrying capacity may include the weight, volume, etc. of the cargo), the starting point of the carrying object is the intermediate station 22, the destination of a part of the carrying object may be, for example, the next station of the intermediate station 22, and the destination of a part of the carrying object may be, for example, the destination station. According to the bearer information sent by each bearer object of the intermediate site 22, it can be determined that the bearer requirement of the intermediate site 22 is 5(5 passengers).
In the above specific embodiment of the present invention, in step S120, the remaining carrying capacity W of the fleet where the command car is located at the intermediate site may be:
W＝S-T+R，
the method comprises the following steps of obtaining a total bearing capacity of a fleet of command vehicles, wherein S is the total bearing capacity of the fleet of command vehicles, T is the bearing capacity of the fleet of command vehicles when the fleet of command vehicles runs to an intermediate site from the last intermediate site, and R is the sum of the bearing capacities of bearing objects taking the intermediate site as a destination.
For example, in the embodiment shown in fig. 2, the total carrying capacity of the fleet of command cars 21 is 10 people, the carrying capacity of the fleet of command cars 21 when traveling to the intermediate station 22 at the previous intermediate station is 9 people, and the number of passengers getting off the fleet of command cars 21 at the intermediate station 22 is 2 people (i.e., the sum of the carrying capacities of the carrying objects destined for the intermediate station 22). Therefore, the carrying residual capacity W of the fleet where the command vehicle is located at the intermediate site can be calculated to be 10-9+ 2-3 people.
The loading demand (5 persons) and the loading residual capacity (3 persons) of the intermediate station 22 are brought into the step S120, and the director vehicle 21 determines that the loading residual capacity of the fleet where the director vehicle 21 is located at the intermediate station is smaller than the loading demand, so that, referring to fig. 3, the director vehicle 21 performs step S130 to broadcast request information for requesting a support vehicle through V2V (the broadcast request information may include a vehicle type, a required capacity, and the like, so that the support vehicle can match according to the vehicle type and the capacity of the vehicle to confirm whether the support vehicle can join the fleet). Then, when the director vehicle 21 receives the support determination information returned from the support vehicle 24 through V2V, the director vehicle 21 transmits the driving data to the support vehicle 24 through V2V to join the support vehicle 24 as a slave vehicle to the fleet of vehicles at step S140. Then, by step S150: the command vehicle 21 controls the fleet to stop at the intermediate site 22, carry the carrying object of the intermediate site 22, and travel to the next intermediate site.
In some preferred embodiments of the present invention, the present invention further includes a step of managing a destination of a carrier object, specifically, before the fleet stops at the intermediate site in step S150, the present invention further includes the following steps:
the command vehicle determines the bearing relationship between the bearing object and the vehicles in the fleet according to the destination of the bearing object of the intermediate site; the command vehicle generates bearing indication information of the bearing object according to the bearing relation between the bearing object and the vehicles in the motorcade; and the command car sends bearing indication information to the bearing object of the intermediate station.
As shown in fig. 3, whether each passenger 23 is carried by the director vehicle 21 or the slave vehicle 24 may be determined based on the destination of the passenger 23 and the remaining capacity of each vehicle in the fleet. Preferably, in the bearing relationship between the bearing object and the vehicles in the fleet determined by the command vehicle: the closer the destination of the bearing object is to the destination station, the closer the bearing object vehicle is to the command vehicle in the fleet.
With continued reference to fig. 3, based on the foregoing calculations, the remaining capacity of the command car 21 to carry is 3, of the 5 passengers at intermediate station 22, 2 are destined for the destination station, and 3 are destined for the next intermediate station of intermediate station 22, then 2 destined for the destination station and 1 of 3 destined for the next intermediate station of intermediate station 22 are carried by command car 21, and the remaining 2 of 3 destined for the next intermediate station of intermediate station 22 are carried by slave car 24. Therefore, the slave vehicles can be released as soon as possible, so that the slave vehicles can be added into other motorcades for supporting, and the whole transportation efficiency is improved. The above description is only an example of the destination management of the bearer object of the present invention, and the present invention is not limited thereto.
In an embodiment of the present invention, the step S140 of joining the support vehicle as a slave vehicle to the fleet of vehicles may comprise the steps of: and adding the support vehicle into the fleet as the tail of the fleet. Thus, the slave vehicle can be released from the rear of the vehicle fleet in accordance with the destination management of the carrying object.
In another embodiment of the present invention, in step S120, if the command vehicle determines that the remaining carrying capacity of the fleet of command vehicles at the intermediate site is greater than or equal to the carrying demand, the fleet may continue to run. In some variations, if the director vehicle determines that the remaining bearing capacity of the fleet of director vehicles at the intermediate site is greater than or equal to the required bearing capacity, the following determining step may be continuously performed:
and stopping the fleet at the intermediate station, wherein at least part of the carrying objects of the fleet reach the destinations of the at least part of the carrying objects, and when the carrying objects are unloaded from the fleet, one or more slave vehicles with zero carrying capacity exist in the fleet, and except for the one or more slave vehicles, when the carrying residual capacity of the fleet where the command vehicle is located at the intermediate station is still larger than or equal to the carrying demand, the one or more slave vehicles are separated from the fleet.
Still taking the passenger transport as an example, when the fleet (including the command car and the slave cars) stops at the intermediate station, 5 persons get off the command car, 8 persons are loaded on the command car at the intermediate station, 3 persons get off the command car from the car a, the load capacity of the command car from the car a is 0, and the load demand of the intermediate station is 5 (less than 8 persons are loaded on the command car at the intermediate station), the fleet is separated from the car a. The foregoing is merely an illustrative description of the embodiments of the present invention and is not intended to limit the invention thereto.
An embodiment of the present invention is described below with reference to fig. 5 to 8. Fig. 5-8 are schematic diagrams illustrating a fleet management method at a plurality of intermediate sites, according to an embodiment of the present invention.
The fleet, in traveling to destination site 22D, needs to stop intermediate sites 22A, 22B, and 22C. Initially, the fleet only includes a command vehicle, the command vehicle 21 determines the load-bearing demand of the load-bearing object of the intermediate station 22A before stopping the intermediate station 22A, and determines that the load-bearing residual capacity of the command vehicle 21 fleet at the intermediate station 22A is smaller than the load-bearing demand. The director vehicle 21 broadcasts request information requesting a support vehicle through V2V and receives support determination information returned by the support vehicle 241, the director vehicle 21 transmits driving data to the support vehicle 241 through V2V to join the support vehicle 241 as a slave vehicle to the fleet, and the director vehicle 21 controls the fleet (director vehicle 21 and slave vehicle 241) to stop at the intermediate station 22A, bear a bearing object of the intermediate station 22A, and drive to the next intermediate station 22B. The command vehicle 21 determines the load-bearing demand of the load-bearing object of the intermediate station 22B before stopping the intermediate station 22B, and judges that the load-bearing residual capacity of the command vehicle 21 fleet at the intermediate station 22B is less than the load-bearing demand. The director vehicle 21 broadcasts request information requesting a support vehicle through V2V and receives support determination information returned by the support vehicle 242, the director vehicle 21 transmits driving data to the support vehicle 242 through V2V to join the support vehicle 242 as a slave vehicle to the fleet (as the tail of the fleet), and the director vehicle 21 controls the fleet (director vehicle 21 and slave vehicles 241, 242) to stop at the intermediate station 22B, carry the carrying object of the intermediate station 22B, and drive to the next intermediate station 22C. The command vehicle 21 determines the carrying demand of the carrying object of the intermediate station 22C before passing through the intermediate station 22C, and determines that the carrying residual capacity of the command vehicle 21 fleet at the intermediate station 22C is greater than or equal to the carrying demand, and further determines that the carrying capacity of the slave vehicle 242 after passing through the intermediate station 22C is zero, and the carrying residual capacities of the command vehicle 21 and the slave vehicle 241 are still greater than or equal to the carrying demand. The director vehicle 21 controls the fleet (director vehicle 21 and slave vehicles 241, 242) to stop the intermediate site 22C, so that the slave vehicle 242 leaves the fleet, and the director vehicle 21 and the slave vehicle 241 carry the carrying object of the intermediate site 22C and travel to the next intermediate site 22D. And so on until the fleet travels to destination site 22D.
