Description

DESCRIPTION TITLE: Method and system for providing assistance in moving motor vehicles in a logistics environment Technical field of the invention

[0001] The present invention relates to the field of logistics. The invention relates in particular to a method for providing, by a computer system, assistance in moving a set of motor vehicles between a first location and a second location in a logistics environment. The invention also relates to a computer system implementing such a method. The invention applies to logistics environments in which the movement of manufactured motor vehicles must be optimized. State of the prior art

[0002] In a motor vehicle manufacturing plant, a new vehicle arrives at the end of the assembly line every minute. Each newly manufactured motor vehicle is moved from the assembly line to a battery charging area, where the battery of the newly manufactured vehicle is fully charged for a variable period ranging from 1 to 30 minutes. Each battery charger is connected to a control system that distinguishes three different states: the vehicle is mainly charging, i.e., the battery level is below a predefined level, indicated by a red light; the battery is already charged, i.e., the battery level is above a predefined level, indicated by a green light; and a charging cable is disconnected, indicated by a flashing green light.

[0003] Once the battery of each newly manufactured motor vehicle is fully charged, the vehicle must be moved to a parking area so that it can then be picked up by a carrier who transports it to its final destination. Before reaching the battery charging area, the vehicle has already been assigned a space in the parking area by a transport management system. The system that assigns the parking space to the newly manufactured vehicle and the one that monitors the battery status of each vehicle in the battery charging area are usually two independent systems.

[0004] To move the vehicles from the battery charging area to the parking area, a team is formed by drivers (3 to 7 people responsible for driving the newly manufactured vehicles) and a supervisor who follows the drivers to the parking area, picks up all the drivers and brings them back to the battery charging area to start the process again.

[0005] Each time the supervisor returns to the battery charging area with all drivers on board, they must choose a specific vehicle at that location, with the only criterion so far being to monitor the status of the chargers' indicator lights (indicating available vehicles) and, based on the supervisor's experience, decide which vehicles to choose. This means that selected vehicles may well have to be moved to locations relatively far from each other in the parking area, which implies more time to move the vehicles, poor resource optimization and, potentially, saturation of the assembly line if no other team (drivers and supervisor) is available.Furthermore, in the current setup, the supervisor has to wait for all drivers until they pick up their vehicles, and then track them to find out where they are going to park the vehicles they have just picked up. Again, time is lost, which impacts the flow of the process and leads to a risk of disruption to production capacity.

[0006] No solution is currently available to optimize this process in order to save time and facilitate the work of supervisors and drivers. Summary of the invention

[0007] The invention aims to meet these needs. The objective of the invention is in particular to provide a solution to facilitate the tedious process explained above of moving newly manufactured vehicles in a logistics environment which includes a battery charging area and a parking area far from each other. To this end, the invention aims to provide a method and a system which facilitate the work of the personnel in charge, drivers and supervisors, by fully automating it, in particular for the selection of vehicles to be moved and for the practical and clear provision of information which allows the personnel to achieve significant time savings.In this way, the invention aims to improve the fluidity of the vehicle movement process in such a specific logistics environment as mentioned above, and thus contribute to securing the productivity of a motor vehicle assembly plant.

[0022] Other characteristics and advantages of the invention will appear on examining the detailed description below and the attached drawings, in which:

[0028] Figure 1 schematically illustrates a system 100 according to the invention for providing assistance in moving a set of motor vehicles forming part of a fleet of one or more manufactured motor vehicles between a first location and a second location of a logistics environment of a motor vehicle manufacturing plant, the first location being a battery charging area in which a plurality of chargers are installed and the second location being a parking area where the vehicles are stored before their transport.It is basically a computer system, which comprises a computer device 102, for example a server, which comprises an information processing unit 110, with one or more processors, and a data storage medium 112, on which is recorded in particular a program which comprises program code instructions for the execution by the information processing unit 110 of the steps of the method according to the invention described below. Conventionally, the device 102 according to the invention further comprises hardware and software means for connecting to a wireless communication network 104 in order to communicate by means of conventional communication protocols with a first mobile communication device 106 and a second mobile communication device 108.In the context of the invention, the first mobile communication device 106 is owned by a supervisor, while the second mobile communication device 108 is owned by a driver.

[0029] Figure 2 schematically illustrates in more detail the components of the device 102 of the system 100 according to the invention. This comprises in particular a charging status monitoring module 202, an end-of-charging detection module 204, a position allocation module 206, a tracking module 208, a movement status detection module 210, a management module 212, a digital representation generation module 214, a coordinate conversion module 216 and a logistics optimization module 218. Alternatively, the position allocation module 206 may be part of an external system connected to a transport management system, and may be connected to the system 100 according to the invention, in particular to its device 102, by means of a local communication network. Furthermore, as seen in FIG. 3, the management module 212 comprises a filtering module 302 and a merging module 304.

[0030] According to the invention, all the elements described above contribute to enabling the implementation of a method for providing assistance in moving a set of motor vehicles forming part of a fleet of one or more manufactured motor vehicles between a first location and a second location in a logistics environment, the first location being a battery charging area in which a plurality of chargers are installed and the second location being a parking area. This method is described below in connection with Figures 2-5.

[0031] Figure 4 illustrates a flowchart of the method according to the invention. According to a first step 401 of the method, the device 102 receives data characterizing a request from the first mobile communication device 106. This data advantageously includes a number of drivers available to participate in said movement of a set of vehicles from the first location to the second location. To submit the request, the first mobile communication device 106 conventionally comprises a user interface, as described below. Furthermore, as already mentioned above, the first mobile communication device 106 is held by a supervisor. This received request therefore corresponds to the initial situation in which the supervisor requests to initiate the movement of a set of vehicles present in the battery charging zone depending on the availability of drivers.

[0032] According to a second step 402, the management module 212 determines the data characterizing a first set of information. The first set of information stipulates an identification number, a first position in the first location, a state of charge and a second position in the second location. This information is determined for each of the motor vehicles manufactured, in other words all the vehicles which are located in the battery charging area.

[0033] The vehicle identification number (VIN) and the second position in the second parking space for each vehicle are pre-established. In other words, an identification number and a parking space are already assigned to each newly manufactured motor vehicle. In particular, it is the position allocation module 206 that assigns the second position, i.e. its position in the parking area, to each newly manufactured vehicle.

[0034] To determine the state of charge, the device 102 uses the state of charge monitoring module 202 and the end of charge detection module 204. The state of charge monitoring module 202 is configured to determine data characterizing a charging condition of each vehicle during its charging in the battery charging area. The data characterizing a charging condition includes at least the current state of the battery of each vehicle and the state of the connection of the battery (or the vehicle) with a charger. For example, the current state of the battery can be a charging state or a charged state. The connection state of the battery can be a connected state or a disconnected state. In the charging state, the battery is being charged and the charger is connected. In the charged state, the battery is fully charged and the load is disconnected (i.e., the battery is disconnected from the charger).A load condition associated with each vehicle is detected by the module. monitoring of the state of charge 202 and transmitted to the end of charge detection module 204. The end of charge detection module 204 determines data characterizing the state of charge, for each of the vehicles manufactured, on the basis of the data characterizing a charging condition. The end of charge detection module 204 transmits the data characterizing the state of charge to the management module 212.

[0035] In one embodiment, the end-of-charge detection module 204 generates a report of operations in the battery charging area based on data characterizing the state of charge. The report may indicate the state of each vehicle being charged in the battery charging area. The report may include the identification number of a motor vehicle being charged, the state of charge, and the first position of the vehicle in the first location. Once a vehicle is disconnected from its charger and moved to the second location, the data associated with that motor vehicle is deleted from the report, and new data associated with a newly manufactured vehicle is added to the report. In one embodiment, the report may be generated in a text file and may be saved to a database at a predefined interval.The text file can be extracted from the database to be processed by the management module 212. .

[0036] With regard to the tracking module 208, this is configured to obtain the current location of each vehicle in the set of motor vehicles, those which are currently moving. To do this, it organizes communications with each of the location systems on board the vehicles in real time. The movement state detection module 210 establishes whether a vehicle which has left the first position from the first location, i.e. the battery charging zone, has reached the second position in the second location, i.e. the parking zone.

[0037] To determine the data characterizing the first set of information, the management module 212 uses its filtering module 302 and its merging module 304. The filtering module 302 filters data characterizing a plurality of sets of information corresponding to each of the manufactured vehicles by removing unnecessary data. The unnecessary data may be aberrant data, redundant data or data corresponding to vehicles already transferred to the parking area. The merging module 304 integrates the data characterizing the useful information of the plurality of sets of information and generates data characterizing a merged set of information. The data characterizing a plurality of sets of information correspond to each manufactured vehicle. They are received from the end-of-charge detection module 204, the position allocation module 206 and the travel state detection module 210.The merging module 304 further establishes a relationship between vehicle information and position information based on the data characterizing a merged information set. This is how the data characterizing a first information set is determined during this second step 402 of the method according to the invention. The vehicle information may be the identification number and the state of charge. The position information may be the first position in the first location and the second position in the second location, or a current location. It should be remembered that it is the position allocation module 206 that allocates to each of the newly manufactured motor vehicles its second position in the second location, in other words its parking space before transport.

[0038] According to a third step 403 of the method according to the invention, the coordinate conversion module 216 determines data characterizing a second set of information on the basis of the data characterizing a first set of information, those determined during the previous step, and a digital representation of said logistics environment, in other words, a digital map. The coordinate conversion module 216 is configured to receive the digital representation of the logistics environment from the digital representation generation module 214. The digital representation of the logistics environment includes the first location and the second location, in other words, the battery charging area and the parking area. The digital representation of the logistics environment provides detailed information about all singular points of the logistics environment. The digital representation of the logistics environment can be created, by the digital representation generation module 214, using topographical information including details such as lane width, edge, number of lanes, direction.This digital representation is developed using a local coordinate system in which the origin position (0,0) is located in the logistics environment.

[0039] To determine the data characterizing a second set of information, the data characterizing a first set of information is normalized by the coordinate conversion module 216. The coordinate conversion module 216 further extracts the first position and the second position of each of the manufactured vehicles from the data characterizing a first set of information and generates local coordinates corresponding to the digital representation of the logistics environment for the first position and the second position of each of the manufactured vehicles.

[0040] The coordinate conversion module 216 is further configured to determine a distance between the first and second positions based on the local coordinates for each manufactured motor vehicle. Thus, the second set of information determined during this third step 403 of the method comprises the digital representation of the logistics environment related to the first position and the second position of each of the vehicles manufactured, as well as the distance between the first position and the second position for each of the vehicles manufactured.

[0041] According to a fourth step 404 of the method according to the invention, the logistics optimization module 218 uses the data characterizing a second set of information in order to determine data characterizing a set of motor vehicles, in other words it determines the vehicles which must be moved from the first location to the second location. To do this, the logistics optimization module 218 takes into account a travel time for each of the vehicles present in the first location in order to move them from their first position to their second position in the second location. It is understood that the travel time of each of the vehicles from the first location to the second location corresponds to the travel time between the first location and the second location.The logistics optimization module 218 also takes into account the recovery time required by the supervisor to pick up all the drivers and bring them back to the first location. It should be noted that the number of vehicles selected for moving the vehicles from the first to the second location corresponds to the number of available drivers stipulated by the supervisor in the request received during the first step 401 of the method.

[0042] Furthermore, the logistics optimization module 218 transmits the data characterizing all of the motor vehicles to the travel state detection module 210. The travel state detection module 210 determines, in real time, the travel state of each of the vehicles and informs the data management module 212 once all of the vehicles in the selected set of vehicles have been moved to the second location.

[0043] Preferably, the logistics optimization module 218 determines a set of motor vehicles to be moved from the first location to the second. location based on data characterizing the second position for each manufactured motor vehicle, data characterizing a maximum distance to be traveled by the drivers to reach the corresponding second locations, data characterizing a time elapsed since each manufactured motor vehicle was loaded, the duration of the trip and the recovery time. To do this, the logistics optimization module 218 proceeds for example by implementing the mathematical implementation explained below.

[0044] The problem of identifying a set of k vehicles from m vehicles can be defined as follows:

[0045] si ^^ ൌ ^^^^, ^^^, … , ^^^^ est un ensemble de places de stationnement, où ^^ ^ is a position of the battery charging area,

[0046] si ^^’ ൌ ^^\^^^^^ est un ensemble de n places de stationnement,

[0047] si ^^ ൌ ^^^^^,^^^^ | ^^^ ,^^^ ∈ ^^ ; ^^ ് ^^^ est un ensemble d'arcs,

[0048] if C is a matrix of non-negative distances between parking spaces ^^ ^^ between the parking spaces ^^ ^ and ^^ ^ ,

[0049] if T is a vector of non-negative values ​​^^ ^ , where ^^ ^ is the time that has elapsed since each vehicle was loaded and available to go to the parking space ^^ ^ ,

[0050] yes ^^ ^ is a route for the vehicle ^^,

[0051] if m is a number of motor vehicles manufactured (all identical), with a route assigned to each motor vehicle manufactured,

[0052] then a solution according to the logistics optimization module 218 can be composed

[0053] d’une partition ^^^ , … , ^^^ de ^^

[0054] and a permutation of ^^ ^ ⋃ 0 specifying an order of parking spaces on road i.

[0055] Le coût d'un itinéraire donné ^^^^^ ൌ ^ ^^^,^^^, … , ^^^ା^^, où ^^^ ൌ ^^^ା^ ൌ0 (the 0 indicates the battery charging area), is given by:

[0056] ^^^^^^^ ൌ ^^ ∑ ^ ^ୀ^ ^^^,^ା^ െ ^^∑^ ^ ୀ^ ^^^

[0057] , where ^^ and ^^ are weighting functions that allow weighting to be given to the time elapsed since the vehicle was loaded and the distance between the first and second positions. A setting of the weighting functions can be stipulated depending on the logistics environment. The logistics optimization module 218 can further be adapted depending on an input from an operator. In other words, for example, a priority of vehicles to be moved to the parking area can be specified, and such a parameter with a given weight, in the optimization process, thus allows the determination of a set of vehicles to be moved to be adapted in real time to particular needs. Furthermore, the logistics optimization module 218 determines, on the basis of which vehicles are moved first to the parking area, in which order the drivers of these vehicles are then picked up.

[0058] Finally, according to a fifth step 405, the device 102 causes the display, on the first mobile communication device 106, and therefore intended for the supervisor, of the data characterizing the set of vehicles selected for movement from the first position to the second position, with the corresponding information. The data characterizing the set of Vehicles include information about each vehicle, such as an identification number, a corresponding second position, and a route for each driver to follow from the first position to the second position. This allows the supervisor to go directly to the parking area as soon as the drivers have retrieved their vehicles from the battery charging area, significantly reducing recovery time.

[0059] Then, the device 102 causes the display of the data characterizing all the motor vehicles on the second mobile communication device 108, in other words for the drivers. Thus, the drivers can see and know which vehicles they must take in the battery charging zone.

[0060] When all drivers have been picked up and returned to the first location, the supervisor can end the process by submitting a new request.

[0061] Figure 5 illustrates an example of the user interface 500 displayed on the first mobile communication device 106. This is divided into several areas, for example, a first display area 502, a second display area 504, a first input element 508 and a second input element 510. The first display area 502 provides the digital representation of the first location 502A indicating the first position of each vehicle of the set of vehicles waiting to move and a digital representation of the second location 502B indicating the second position of each vehicle of the set of selected vehicles.

[0062] When a request is submitted by interacting with the first input element 508, the supervisor can indicate the number of available drivers and the method according to the invention is initiated. The logistics optimization module 218 then identifies a set of motor vehicles among the manufactured vehicles that are available at the first location 502A, i.e., the battery charging area. The second position of the selected vehicles in the second location 502B is also indicated. The first display area 502 may also indicate the shortest path between the first position and the second position for each of the vehicles identified for movement. The shortest path may be determined using a conventional planning algorithm (i.e., A*, fast random trees, or any other solution). The second display area 504 may display a first position and a second position as well as the identification number of each vehicle. In the illustrated example, three vehicles are selected to be moved from the first to the second location. The first and second positions of the three identified vehicles are displayed in the second display area 504.
