Referring to fig. 1 and fig. 2, fig. 1 is a schematic view of an application scenario of a mobile hydrogenation vehicle scheduling method according to an embodiment of the present invention; fig. 2 is a schematic flow chart of a mobile hydrogenated vehicle scheduling method provided in an embodiment of the present invention, where the mobile hydrogenated vehicle scheduling method is applied in a server, and the method is executed by application software installed in the server.

As shown in fig. 2, the method includes steps S101 to S105.

S101, responding to a hydrogenation rescue instruction sent by a vehicle machine of a vehicle, and acquiring vehicle positioning information, vehicle contact information and a vehicle navigation planning path corresponding to the hydrogenation rescue instruction; and the vehicle contact information comprises a vehicle contact person number and the current residual hydrogen energy source parameters of the vehicle.

In this embodiment, the technical solution is described with a server as an execution subject. The server can also be understood as a background server, which is in communication connection with a vehicle machine on a hydrogen energy automobile (simply referred to as a vehicle, which in this application is a role of a vehicle to be hydrogenated of a rescued vehicle) and a vehicle machine on a hydrogenation rescue vehicle (for example, a connection is established through a wireless network such as a 5G network), and the server is also in communication connection with a receiving terminal of each hydrogenation station. Therefore, the server can receive various information and data uploaded by respective vehicle machines of a plurality of hydrogen energy vehicles under the condition of user authorization in real time, also can receive various information and data uploaded by receiving terminals of various hydrogen stations, and performs centralized processing on the received information and data.

In the application, a user drives a hydrogen energy automobile to be a specific scene, when the user starts the hydrogen energy automobile, a car machine (such as a vehicle-mounted touch screen on a center console is a part of the car machine) is also in a starting operation state, and the user can operate a hydrogenation rescue virtual button on a user interaction interface of the car machine to trigger to generate a hydrogenation rescue instruction at any time, so that the user does not need to operate a mobile phone to make a manual rescue call to request rescue, and the rescue request is initiated at any time on the premise of ensuring the driving safety of the user. Once a user operates a hydrogenation rescue virtual button on a vehicle user interface to trigger to generate a hydrogenation rescue command, after the hydrogenation rescue command is sent to a server, the server firstly obtains and uploads vehicle positioning information, vehicle contact information and a vehicle navigation planning path corresponding to a command to be hydrogenated of the vehicle.

The vehicle positioning information is used for representing the current positioning position of the hydrogen energy vehicle when a hydrogen rescue instruction is initiated; the vehicle contact information at least comprises a vehicle contact number (contact information used for representing the current driver of the vehicle, such as a mobile phone number can be used as a vehicle contact number), a current residual hydrogen energy parameter of the vehicle (the current residual hydrogen energy parameter of the vehicle is represented, for example, the residual hydrogen energy parameter can be represented by the percentage of the actual residual hydrogen energy capacity to the total hydrogen energy capacity of the vehicle), and a vehicle navigation planning path (which represents navigation data of the vehicle, and the starting point and the end point of the vehicle and the specific driving direction along the path can be obtained based on the vehicle navigation planning path). After the server obtains the hydro-rescue instruction, a nearby safe parking area can be automatically obtained based on the vehicle positioning information to guide the vehicle to firstly drive to a safe area for hydro-rescue waiting.

S102, if the road type corresponding to the vehicle positioning information is determined to be the expressway type, obtaining safe parking area positioning information corresponding to the vehicle positioning information, and sending the safe parking area positioning information to the vehicle machine.

In this embodiment, when a general vehicle runs on a highway, if the remaining hydrogen energy is insufficient, the vehicle is a service area near a pilot navigation, and if the remaining hydrogen energy is insufficient to support the vehicle to run to the nearby service area, the vehicle can only be parked in a safe parking area (such as an emergency lane) near the pilot navigation to wait for rescue. Therefore, when it is determined that the road type corresponding to the vehicle positioning information is an expressway type, the server screens and acquires the safe parking area positioning information corresponding to the vehicle positioning information (generally, a safe parking area with the minimum distance from the position corresponding to the vehicle positioning information and a positioning position corresponding to the safe parking area are acquired, and the front direction of the full parking area in the current driving direction of the vehicle is better), and then the server sends the safe parking area positioning information to the vehicle machine. Therefore, based on the automatic and rapid acquisition of the positioning information of the safe parking area, the current navigation route (for example, the navigation route of the newly added road passing the positioning position corresponding to the positioning information of the safe parking area) on the vehicle machine can be updated in time, manual operation is not needed, and the safety is improved.

In one embodiment, step S102 includes:

acquiring a highway positioning position corresponding to the vehicle positioning information;

acquiring safe parking area positioning positions, the distance between which and the highway positioning positions does not exceed a preset first distance threshold value, so as to form an initial screening positioning position set;

obtaining the current residual hydrogen energy source parameters of the vehicle, and determining the estimated driving distance according to the current residual hydrogen energy source parameters of the vehicle;

acquiring and deleting initial screening positioning positions of which the distance between the initial screening positioning position set and the expressway positioning position exceeds the estimated driving distance so as to update to obtain a secondary screening positioning position set;

acquiring a current driving direction corresponding to the vehicle navigation planning path, and acquiring secondary screening and positioning positions, which have the same connecting line direction with the highway positioning positions and the current driving direction, in the secondary screening and positioning position set to form a tertiary screening and positioning position set;

and acquiring the tertiary screening positioning positions with the minimum distance between the tertiary screening positioning position set and the highway positioning positions as the safe parking area positioning information.

In this embodiment, in order to obtain the location information of the safe parking area more quickly and accurately, an expressway location position corresponding to the vehicle location information (specifically, the longitude and latitude of the position where the vehicle is located, the expressway name corresponding to the longitude and latitude, and the expressway location position) needs to be obtained first, then a preset first distance threshold is obtained (for example, the first distance threshold is set to 2 km, and is limited to 2 km in the specific implementation, and may also be set to other reasonable distance values according to the actual requirements, for example, when a general vehicle prompts that the remaining energy is close to or equal to 0, some remaining energy is reserved to ensure that the vehicle travels to a nearest hydrogen refueling station, and more specifically, when the supportable vehicle travels at a distance of 10 km, the first distance threshold may also be set to 10 km at the maximum), then, the nearby part which is screened by combining the expressway location position and the first distance threshold and which satisfies the expressway location position corresponding to the expressway location position The distance between the safe parking area positioning positions does not exceed a preset first distance threshold value so as to form an initial screening positioning position set. It can be seen that the initial screening location positions screened out based on this way are all possible to be candidate safe parking areas.

In order to more reasonably determine the best safe parking area in a plurality of initial screening positioning positions included in the initial screening positioning position set, an estimated driving distance is determined based on the current residual hydrogen energy parameters of the vehicle (an estimation algorithm is stored in a common vehicle and used for converting the current residual hydrogen energy parameters of the vehicle into corresponding estimated driving distance), and then the initial screening positioning position with the distance between the initial screening positioning position set and the expressway positioning position exceeding the estimated driving distance is deleted to update to obtain a secondary screening positioning position set. And by secondary screening, a safe area where the vehicle cannot run is removed, and a secondary screening and positioning position set consisting of more reasonable candidate safe parking areas is obtained.

At this time, since some safe parking areas are not in the same direction as the current driving direction of the vehicle, that is, the vehicle needs to reverse the driving direction to reach, and the driving direction cannot be reversed on the highway, the safe parking areas which are not in the same direction as the current driving direction of the vehicle are difficult to reach. At this time, the current driving direction corresponding to the vehicle navigation planning path may be obtained, and secondary screening and positioning positions having the same direction as the current driving direction with respect to the connection line between the secondary screening and positioning positions and the highway positioning position may be obtained in the secondary screening and positioning position set to form a tertiary screening and positioning position set. After the tertiary screening and positioning position set is obtained, a target tertiary screening and positioning position with the minimum distance to the expressway positioning position can be selected from the tertiary screening and positioning position set, and the longitude and latitude of the target tertiary screening and positioning position are obtained and used as the safe parking area positioning information. Therefore, the safe parking area positioning information acquired based on the intelligent screening mode not only belongs to the same-direction forward passable place with the current driving direction of the vehicle, but also is the safe parking area which is the closest distance to the expressway positioning position of the vehicle, so that the vehicle can be quickly and effectively guided to drive to a safe area to wait for hydrogenation rescue.

In an embodiment, the obtaining a current driving direction corresponding to the vehicle navigation planned path and obtaining, in the secondary screening and positioning location set, secondary screening and positioning locations having a same connection direction with the highway positioning location as the current driving direction to form a tertiary screening and positioning location set includes:

acquiring a first direction vector corresponding to the current driving direction;

obtaining second direction vectors corresponding to connecting lines between the secondary screening positioning positions in the secondary screening positioning position set and the expressway positioning positions to form a second direction vector set;

acquiring a second direction vector with a vector included angle of 0 degrees between the second direction vector set and the first direction vector to form a target second direction vector set;

and acquiring secondary screening and positioning positions corresponding to the second direction vectors of the targets in the second direction vector set of the targets to form a tertiary screening and positioning position set.

In this embodiment, when the first direction vector corresponding to the current driving direction is obtained, the highway location position of the vehicle may be used as a starting point, and then the position reached by the vehicle after 1 minute is used as an end point, and the first direction vector is determined based on a connection line between the starting point and the end point. Similarly, the second direction vectors corresponding to the secondary screening positioning positions in the secondary screening positioning position set may be respectively determined to form a second direction vector set based on a connection line between the end point corresponding to each secondary screening positioning position in the secondary screening positioning position set and the expressway positioning position of the vehicle as the start point. At this time, a second direction vector having a vector angle of 0 degree with the first direction vector may be obtained by screening from the second direction vector set, so as to form a target second direction vector set. And finally, forming a third screening and positioning position set by the secondary screening and positioning positions corresponding to the second direction vectors of the targets in the second direction vector set of the targets. Therefore, which screening and positioning positions belong to the places which can be passed by the same-direction forward road with the current driving direction of the vehicle can be quickly and accurately determined based on the direction vector.

S103, if a first determination instruction corresponding to the safe parking area positioning information is received, acquiring a preferred hydrogenation station positioning information set corresponding to the safe parking area positioning information, and sending the preferred hydrogenation station positioning information set to the vehicle machine.

In this embodiment, after the safe parking positioning information is obtained in the server to the vehicle machine of the vehicle, the vehicle machine prompts the user whether to determine to navigate to the safe parking area positioning information, that is, a confirmation prompt box pops up on a display screen of the vehicle machine, and when the user touches a determination button in the selected confirmation prompt box, a first determination instruction is triggered to be generated and sent to the server by the vehicle machine. When the server receives the first determination instruction, the server knows that the driver of the vehicle plans to drive to the safe parking area corresponding to the safe parking area positioning information. Moreover, the server may further screen out a preferred hydrogen station positioning information set corresponding to the safe parking area positioning information, preferably screen out a selected hydrogen station positioning position where a distance between positions corresponding to the safe parking area positioning information does not exceed a preset second distance threshold, so as to form the preferred hydrogen station positioning information set by the preferred hydrogen station positioning information corresponding to the selected hydrogen station positioning position. Therefore, the nearby hydrogenation stations are screened based on the positioning information of the safe parking area to mobilize the hydrogenation rescue vehicle, the rescue efficiency can be effectively improved, and the time required by hydrogenation rescue is reduced.

In one embodiment, step S103 includes:

acquiring the hydrogenation station positioning positions of which the distance between the positions corresponding to the safe parking area positioning information does not exceed a preset second distance threshold value to form an optimal hydrogenation station positioning position set;

and acquiring the positioning information of the preferred hydrogenation station corresponding to the positioning position of each preferred hydrogenation station in the positioning position set of the preferred hydrogenation station to form a positioning information set of the preferred hydrogenation station.

In this embodiment, since the server knows the location corresponding to the location information of the safe parking area, the server may further obtain the location information of each hydrogen refueling station from the location information of the plurality of hydrogen refueling stations (that is, may locate the longitude and latitude of the location of each hydrogen refueling station), so that after further knowing a preset second distance threshold, the server may screen out the hydrogen refueling station location locations whose distance from the location corresponding to the safe parking area location information does not exceed the preset second distance threshold, so as to form a preferred hydrogen refueling station location set. Since each preferred hydrogen station location in the set of preferred hydrogen station locations corresponds to location information for one hydrogen station, the set of preferred hydrogen station location information can be obtained based on the set of preferred hydrogen station locations.

In an embodiment, step S103 is followed by:

and sending navigation end point information corresponding to the positioning information of the safe parking area and a navigation end point information updating instruction to the vehicle machine.

In this embodiment, after the safe parking area positioning information is determined in the server, in order to automatically assist the car machine in performing addition of navigation path locations, navigation end point information and a navigation end point information update instruction corresponding to the safe parking area positioning information may be sent to the car machine. Therefore, when the vehicle receives the navigation end point information and the navigation end point information updating instruction, the navigation path determined according to the expressway positioning position and the position corresponding to the navigation end point information is automatically added to the vehicle navigation planning path based on the navigation end point information updating instruction, and the vehicle navigation planning path which comprises the route navigation and is updated is obtained. Therefore, the route can be automatically added to the vehicle navigation planning path based on the method, manual operation of a user is not needed, personal safety of a driver is ensured, and the navigation data updating efficiency is improved.

And S104, if a second determination instruction corresponding to the preferred hydrogenation station positioning information set is received, obtaining target preferred hydrogenation station positioning information corresponding to the second determination instruction.

In this embodiment, after the preferred hydrogen refueling station positioning information set is sent to the in-vehicle device by the server, the preferred hydrogen refueling station positioning information set is displayed in a list form on a display screen of the in-vehicle device, at this time, a user may select one of the preferred hydrogen refueling station positioning information sets through voice control or touch operation to trigger generation of a second determination instruction, and at this time, the selected preferred hydrogen refueling station positioning information is sent to the server as target preferred hydrogen refueling station positioning information corresponding to the second determination instruction. By the method for determining the target-optimized hydrogenation station positioning information, a driver of the vehicle can select the target-optimized hydrogenation station positioning information according to the actual requirement of the driver and correspondingly send out hydrogenation rescue information.

S105, generating a hydrogenated vehicle scheduling instruction according to the vehicle contact information, the target preferred hydrogenated station positioning information and the safe parking area positioning information, and sending the hydrogenated vehicle scheduling instruction to a receiving terminal corresponding to the target preferred hydrogenated station positioning information.

In this embodiment, since the vehicle contact information, the target preferred hydrogen station positioning information, and the safe parking area positioning information corresponding to the vehicle to be rescued are known in the server, at this time, a hydrogen vehicle dispatching command at least including the 3 information (i.e., the vehicle contact information, the target preferred hydrogen station positioning information, and the safe parking area positioning information) may be generated according to the 3 information, and the hydrogen vehicle dispatching command is sent to the receiving terminal corresponding to the target preferred hydrogen station positioning information, thereby completing the sending process of the directional hydrogen vehicle dispatching command.

In an embodiment, step S105 is followed by:

and if receiving rescue starting information sent by a receiving terminal corresponding to the target optimized hydrogenation station positioning information, sending the rescue starting information to the vehicle-mounted device for displaying.

In this embodiment, after the receiving terminal used by the target hydrogen refueling station corresponding to the target preferred hydrogen refueling station positioning information receives the hydrogen refueling vehicle scheduling instruction sent by the server, the receiving terminal can operate in time and respond to the hydrogen refueling vehicle scheduling instruction, and when a hydrogen refueling rescue vehicle starts, rescue starting information is sent to the vehicle-mounted device for display. The rescue starting information at least comprises the name of the hydrogenation station and the license plate information of the hydrogenation rescue vehicle. At the moment, the rescue starting information is displayed on the vehicle-mounted device, so that a driver of the vehicle can be more intuitively informed of the existing rescue starting, and the specific vehicle to be dispatched is definitely displayed to participate in the hydrogenation rescue.

In an embodiment, step S105 is followed by:

if the road type corresponding to the vehicle positioning information is determined to be a non-expressway type, acquiring a set of positioning positions of the parking area included in the vehicle navigation planning path, and sending the set of positioning positions of the parking area to the vehicle machine;

if a third determination instruction corresponding to the positioning position set of the parking area along the way is received, acquiring parking rescue parking positioning information to be parked corresponding to the third determination instruction, and sending the parking rescue positioning information to be parked to a hydrogenation rescue vehicle which has the minimum distance with the parking rescue positioning information to be parked and is in an online state.

In this embodiment, if the vehicle is running on a non-expressway (such as a national road, a provincial road, or other type of road), and if the vehicle is navigating to a nearest convenient parking area to wait for hydrogenation rescue when the remaining hydrogen energy is insufficient, the on-road parking area positioning position set included in the vehicle navigation planned path may be obtained first, and the on-road parking area positioning position set is sent to the vehicle machine. In the route corresponding to the vehicle navigation planning route, since some waypoint parking regions (such as parking lots or places such as roadside parking spaces) may be included, at this time, a waypoint parking region positioning position set composed of some candidate waypoint parking region positioning positions may be sent to the vehicle machine. And at the moment, the vehicle machine displays the set of the positioning positions of the parking areas in a list form, and once the driver of the vehicle is detected to select one of the positioning positions of the parking areas, a third determination instruction is triggered to be generated and sent to the server by the vehicle machine. When the server receives a third determination instruction, the server firstly obtains the positioning information of the rescue parking vehicle which has the minimum distance with the to-be-parked rescue parking positioning information and is in an online state, and then sends the to-be-parked rescue parking positioning information (the to-be-parked rescue parking positioning information comprises the position information corresponding to the selected on-way parking area positioning position, the license plate number of the rescued vehicle and other information) corresponding to the third determination instruction to the vehicle machine of the rescue vehicle. Therefore, the vehicle scheduling is carried out on the non-expressway based on the mode, and the vehicle can be quickly and effectively guided to run to a parking area along the way to wait for the hydrogenation rescue.

According to the method, when the car machine sends the hydrogenation rescue instruction, the positioning information of the safe parking area and the positioning information of the target preferred hydrogenation station can be quickly and automatically determined, and finally, the hydrogenation vehicle scheduling instruction is generated based on the information and sent to the corresponding receiving terminal, so that the efficiency and the safety of navigation to the safe area are improved, and the hydrogenation rescue vehicle can be timely requested to be scheduled.

The embodiment of the invention also provides a mobile hydrogenation vehicle scheduling device, which is used for executing any embodiment of the mobile hydrogenation vehicle scheduling method. Specifically, referring to fig. 3, fig. 3 is a schematic block diagram of a mobile hydrogenated vehicle dispatching device 100 according to an embodiment of the present invention.

As shown in fig. 3, the mobile hydrogen adding vehicle dispatching device 100 includes a first obtaining unit 101, a second obtaining unit 102, an information set obtaining unit 103, a target information obtaining unit 104, and a vehicle dispatching command transmitting unit 105.

The first obtaining unit 101 is configured to obtain, in response to a hydrogenation rescue instruction sent by a vehicle machine of a vehicle, vehicle positioning information, vehicle contact information, and a vehicle navigation planning path corresponding to the hydrogenation rescue instruction; and the vehicle contact information comprises a vehicle contact person number and the current residual hydrogen energy source parameters of the vehicle.

In this embodiment, the technical solution is described by taking a server as an execution subject. The server can also be understood as a background server, which is in communication connection with a vehicle machine on a hydrogen energy automobile (simply referred to as a vehicle, which in this application is a role of a vehicle to be hydrogenated of a rescued vehicle) and a vehicle machine on a hydrogenation rescue vehicle (for example, a connection is established through a wireless network such as a 5G network), and the server is also in communication connection with a receiving terminal of each hydrogenation station. Therefore, the server can receive various information and data uploaded by respective vehicle machines of a plurality of hydrogen energy vehicles under the condition of user authorization in real time, also can receive various information and data uploaded by receiving terminals of various hydrogen stations, and performs centralized processing on the received information and data.

The vehicle positioning information is used for representing the current positioning position of the hydrogen energy vehicle when a hydrogen rescue instruction is initiated; the vehicle contact information at least comprises a vehicle contact number (contact information used for representing a current driver of the vehicle, such as a mobile phone number, which can be used as a vehicle contact number), a vehicle current residual hydrogen energy parameter (residual hydrogen energy parameter used for representing the current vehicle, for example, the residual hydrogen energy parameter can be represented by the percentage of the actual residual hydrogen energy capacity to the total hydrogen energy capacity of the vehicle), and a vehicle navigation planning path (which represents navigation data of the vehicle, and a starting point and an end point of the vehicle and a specific driving direction along the path can be obtained based on the vehicle navigation planning path). After the server acquires the hydro-rescue instruction, a nearby safe parking area can be automatically acquired based on the vehicle positioning information so as to guide the vehicle to drive to the safe area for hydro-rescue waiting.

A second obtaining unit 102, configured to, if it is determined that the road type corresponding to the vehicle positioning information is an expressway type, obtain safe parking area positioning information corresponding to the vehicle positioning information, and send the safe parking area positioning information to the vehicle machine.

In an embodiment, the second obtaining unit 102 is specifically configured to:

acquiring a safe parking area positioning position of which the distance from the expressway positioning position does not exceed a preset first distance threshold value to form an initial screening positioning position set;

acquiring and deleting the initial screening positioning position of which the distance between the initial screening positioning position set and the expressway positioning position exceeds the estimated driving distance so as to update and obtain a secondary screening positioning position set;

In this embodiment, in order to obtain the location information of the safe parking area more quickly and accurately, an expressway location position corresponding to the vehicle location information (specifically, the longitude and latitude of the position where the vehicle is located, the expressway name corresponding to the longitude and latitude, and the expressway location position) needs to be obtained first, then a preset first distance threshold is obtained (for example, the first distance threshold is set to 2 km, and is limited to 2 km in the specific implementation, and may also be set to other reasonable distance values according to the actual requirements, for example, when a general vehicle prompts that the remaining energy is close to or equal to 0, some remaining energy is reserved to ensure that the vehicle travels to a nearest hydrogen refueling station, and more specifically, when the supportable vehicle travels at a distance of 10 km, the first distance threshold may also be set to 10 km at the maximum), then, the nearby part which is screened by combining the expressway location position and the first distance threshold and which satisfies the expressway location position corresponding to the expressway location position The distance between the safe parking area positioning positions does not exceed a preset first distance threshold value so as to form an initial screening positioning position set. It can be seen that the initial screening location screened based on this method is all possible to be a candidate safe parking area.

In order to more reasonably determine the best safe parking area in a plurality of initial screening positioning positions included in the initial screening positioning position set, an estimated driving distance is determined based on the current residual hydrogen energy source parameters of the vehicle (an estimated algorithm is stored in a common vehicle to convert the current residual hydrogen energy source parameters of the vehicle into the corresponding estimated driving distance), and then the initial screening positioning positions with the distance between the initial screening positioning position set and the expressway positioning positions exceeding the estimated driving distance are deleted to update to obtain a secondary screening positioning position set. And by secondary screening, safe areas where the vehicles cannot run are removed, and a secondary screening and positioning position set consisting of more reasonable candidate safe parking areas is obtained.

At this time, since some safe parking areas are not in the same direction as the current driving direction of the vehicle, that is, the vehicle needs to reverse the driving direction to reach, and the driving direction cannot be reversed on the highway, the safe parking areas which are not in the same direction as the current driving direction of the vehicle are difficult to reach. At this time, the current driving direction corresponding to the vehicle navigation planned path may be acquired, and secondary screening positioning positions having the same direction as the current driving direction as the direction of the connection line between the secondary screening positioning positions and the expressway positioning positions are acquired in the secondary screening positioning position set to form a tertiary screening positioning position set. After the tertiary screening and positioning position set is obtained, a target tertiary screening and positioning position with the minimum distance to the expressway positioning position can be selected from the tertiary screening and positioning position set, and the longitude and latitude of the target tertiary screening and positioning position are obtained and used as the safe parking area positioning information. Therefore, the safe parking area positioning information acquired based on the intelligent screening mode not only belongs to the same-direction forward passable place with the current driving direction of the vehicle, but also is the safe parking area which is the closest distance to the expressway positioning position of the vehicle, so that the vehicle can be quickly and effectively guided to drive to a safe area to wait for hydrogenation rescue.

In this embodiment, when the first direction vector corresponding to the current driving direction is obtained, the highway location position of the vehicle may be used as a starting point, and then the position reached by the vehicle after 1 minute is used as an end point, and the first direction vector is determined based on a connection line between the starting point and the end point. Similarly, the second direction vectors corresponding to the secondary screening positioning positions in the secondary screening positioning position set may be respectively determined to form a second direction vector set based on a connection line between the end point corresponding to each secondary screening positioning position in the secondary screening positioning position set and the expressway positioning position of the vehicle as the start point. At this time, a second direction vector with a vector included angle of 0 degree with the first direction vector may be obtained by screening from the second direction vector set, so as to form a target second direction vector set. And finally, forming a third screening and positioning position set by the secondary screening and positioning positions corresponding to the second direction vectors of the targets in the second direction vector set of the targets. Therefore, which screening and positioning positions belong to the places which can be passed by the same-direction forward road with the current driving direction of the vehicle can be quickly and accurately determined based on the direction vector.
