Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.

Fig. 1 and fig. 2 are schematic diagrams of afleet 100 provided in accordance with an embodiment of the present invention. As shown in FIG. 1, afleet 100 includes a plurality ofvehicles 110, where eachvehicle 110 may be equipped with an Internet of vehicles based fleetmanagement control system 300 of the present invention (shown in FIG. 3). During the driving process, the fleetmanagement control system 300 is utilized to communicate with each other among thevehicles 110, and thevehicles 110 can turn on the synchronization mark (e.g., flashing LED mark, infrared laser …, etc.). The fleetmanagement control system 300 determines whether thethird party vehicle 130 is inclined to intervene in thefleet 100; if so, as shown in fig. 2, the fleetmanagement control system 300 shortens the inter-vehicle distance of thevehicles 110 in thefleet 100, thereby effectively preventing the intervention of thethird party vehicle 130.

For further explanation of the vehicle fleetmanagement control system 300, please refer to fig. 1 to 3, and fig. 3 is a block diagram of a vehicle fleetmanagement control system 300 based on internet of vehicles according to an embodiment of the present invention. As shown in fig. 3, the fleet management Control system includes a wireless communication device 310, adetection device 320, a Cooperative-Adaptive Cruise Control (Adaptive Cruise Control)330, and an alert device 340. In terms of architecture, the cooperative adaptive cruise control device 330 is electrically connected to the wireless communication device 310, thedetection device 320 and the warning device 340.

For example, the wireless communication device 310 may include a wireless transceiver based on internet of vehicles, a mobile network communication device, a satellite positioning receiver and/or other wireless transmission module, thedetection device 320 may include an image detection device 321 (also referred to as an image sensing device), a radar sensing device 322, a speed sensing device 323 and/or other sensing devices, the cooperative adaptive cruise control device 330 may be a driving computer, and the warning device 340 may include a lamp, a speaker and/or other warning devices.

During the traveling process, the wireless communication device 310 enables the plurality ofvehicles 110 in thefleet 100 to communicate, thedetection device 320 detects thethird party vehicle 130, and the cooperative adaptive cruise control device 330 determines whether thethird party vehicle 130 tends to intervene in thefleet 100. For example, the cooperative adaptive cruise control device 330 determines whether the third-party vehicle 130 in the image flickers according to the image of the third-party vehicle 130 acquired by the image detection device 321, and if so, determines that the third-party vehicle 130 tends to intervene in thefleet 100. Alternatively, the cooperative adaptive cruise control device 330 determines that the third-party vehicle 130 is inclined to intervene in thefleet 100 when the distance between the third-party vehicle 130 and thefleet 100 is less than the preset safe distance by using the radar sensing device 322.

In the embodiment of the invention, the cooperative adaptive cruise control device 330 utilizes the image detection device 321 to identify whether thethird party vehicle 130 is an emergency vehicle (e.g., police car, ambulance …, etc.). For example, if the image of the third-party vehicle 130 matches the preset emergency vehicle image, the cooperative adaptive cruise control device 330 determines that the third-party vehicle 130 is an emergency vehicle. When thethird party vehicle 130 is an emergency vehicle and is prone to intervene in thefleet 100, the cooperative adaptive cruise control 330 increases the separation of the plurality ofvehicles 110 in thefleet 100.

In another embodiment of the present invention, the cooperative adaptive cruise control 330 utilizes the wireless communication device 310 to determine whether thefleet 100 is between thethird party vehicle 130 and the exit of the interchange. For example, the mobile network communication device may obtain a network map, the satellite positioning receiver may obtain the position of thefleet 100, and the cooperative adaptive cruise control device 330 determines whether thefleet 100 blocks the third-party vehicle 130 from leaving the exit of the interchange according to the position of thefleet 100. When the fleet is between the third-party vehicle and the exit of the interchange, and the third-party vehicle tends to intervene in the fleet, i.e. thefleet 100 blocks the third-party vehicle 130 to the exit of the interchange, the cooperative adaptive cruise control device 330 increases the distance between the plurality ofvehicles 110 in thefleet 100, so that the third-party vehicle 130 leaves the interchange through thefleet 100.

Specifically, if the third-party vehicle 130 is an emergency vehicle, or when thefleet 100 blocks the third-party vehicle 130 to the traffic lane exit, the third-party vehicle 130 needs to intervene, the cooperative adaptive cruise control device 330 estimates the intervention driving point of the third-party vehicle 130 by using thedetection device 320, and performs the distance adjustment of thefleet 100, so that the intervention driving point has a proper distance, and thenearest vehicle 110 senses the driving state of the third-party vehicle 130, and reports thefleet 100 at any time; for example, the speed sensing device 323 senses the speed of the third party and provides the third party with the vehicle to thefleet 100, and notifies thefleet 100 of coordinated acceleration or deceleration if there is a change in speed. After thethird party vehicle 130 leaves thefleet 100, the cooperative adaptive cruise control 330 controls thefleet 100 to readjust to the proper separation.

After determining that the third-party vehicle 130 is inclined to intervene in thefleet 100, if the third-party vehicle 130 is not an emergency vehicle or when thefleet 100 does not block the third-party vehicle 130 to the traffic exit, the cooperative adaptive cruise control device 330 shortens the distance between the plurality ofvehicles 110 in thefleet 100 by using the wireless communication device 310. For example, thefront vehicle 110 in thefleet 100 slows down and therear vehicle 110 accelerates to shorten the vehicle distance.

In practical applications, thethird party vehicle 130 tends to intervene in thefleet 100, and the cooperative adaptive cruise control device 330 may further utilize the image detection device 321 to identify whether there is a white line 190 (as shown in fig. 1) between thethird party vehicle 130 and thefleet 100; if so, the cooperative adaptive cruise control device 330 utilizes the wireless communication device 310 to shorten the distance between thevehicles 110 in thefleet 100 to ensure driving safety.

After the distances between the plurality ofvehicles 110 in thefleet 100 are shortened, the warning device 340 performs a warning action when the cooperative adaptive cruise control device 330 determines that thethird party vehicle 130 is still inclined to intervene in thefleet 100. For example, the lamp emits a flashing warning light or red light warning, and the speaker emits a warning sound.

In practical applications, if the third-party vehicle 130 still has a tendency to intervene in thefleet 100, the cooperative adaptive cruise control device 330 may further utilize the image detection device 321 to identify whether the third-party vehicle 130 is smaller than thevehicle 110; if so, the warning device 340 executes a warning action because there is a potential safety hazard when the small vehicle intervenes between the large vehicles, in other words, the large vehicles will warn to refuse the intervention of thethird party vehicle 130.

After the alert device 340 performs the alert action, the cooperative adaptive cruise control device 330 increases the distance between the plurality ofvehicles 110 in thefleet 100 when it is determined that thethird party vehicle 130 is still prone to intervene in thefleet 100. Specifically, if the third-party vehicle 130 is forced to intervene, the cooperative adaptive cruise control device 330 estimates the intervening driving point of the third-party vehicle 130 by using thedetection device 320, and performs the interval adjustment of thefleet 100, so that the intervening driving point has an appropriate distance, and thenearest vehicle 110 senses the driving state of the third-party vehicle 130, and reports thefleet 100 at any time. After thethird party vehicle 130 leaves thefleet 100, the cooperative adaptive cruise control 330 controls thefleet 100 to readjust to the proper separation.

To further illustrate the operation of the fleetmanagement control system 100, please refer to fig. 4, and fig. 4 is a flowchart of a fleetmanagement control method 400 based on internet of vehicles according to an embodiment of the present invention. As shown in fig. 4, the fleetmanagement control method 400 includes steps S401 to S408 (it should be understood that the steps mentioned in this embodiment, except for the specific sequence, can be performed simultaneously or partially simultaneously, with the sequence being adjusted according to actual needs).

In step S401, a plurality ofvehicles 110 communicate with each other, so that the plurality ofvehicles 110 form thevehicle fleet 100. During travel, thevehicle 110 may turn on a synchronization mark (e.g., flashing LED mark, infrared laser …, etc.).

Next, in step S402, it is determined whether there is a possibility of intervention into the vehicle fleet; specifically, it is determined whether the third-party vehicle 130 tends to intervene in thevehicle fleet 100. For example, in step S402, it is determined whether thethird party vehicle 130 in the image flickers according to the image of thethird party vehicle 130 acquired by the image detection device 321, and if so, it is determined that thethird party vehicle 130 tends to intervene in thefleet 100. Alternatively, in step S402, when the distance between the third-party vehicle 130 and thefleet 100 is less than the preset safety distance by using the radar sensing device 322, it is determined that the third-party vehicle 130 tends to intervene in thefleet 100. On the other hand, if the third-party vehicle 130 does not have a tendency to intervene in thefleet 100, thefleet 100 continues to advance steadily in step S406.

If the third-party vehicle 130 is not likely to intervene in thevehicle group 100, it is determined whether the situation is a special situation in step S403. In step S403, the image detection device 321 is utilized to identify whether the third-party vehicle 130 is an emergency vehicle (e.g., police car, ambulance …, etc.). For example, if the image of the third-party vehicle 130 matches the preset emergency vehicle image, it is determined that the third-party vehicle 130 is an emergency vehicle, which is a special case. In another embodiment of the present invention, the wireless communication device 310 is utilized to determine whether thefleet 100 is between the third-party vehicle 130 and the exit of the interchange. For example, the mobile network communication device may obtain a network map, the satellite positioning receiver may obtain the position of thefleet 100, and in step S403, determine whether thefleet 100 blocks the third-party vehicle 130 from leaving the exit of the interchange according to the position of thefleet 100; if so, this is particularly the case.

If it is a special case (i.e., thethird party vehicle 130 is an emergency vehicle), the separation of thevehicles 110 in thefleet 100 is increased to give the third party vehicle 130 a gift to intervene. Specifically, in step 407, thedetection device 320 is used to estimate the third-party vehicle 130 to intervene in the driving point to adjust the distance between thefleet 100, so that the intervening driving point has an appropriate distance, and thenearest vehicle 110 senses the driving state of the third-party vehicle 130 to report thefleet 100 at any time; for example, the speed sensing device 323 senses the speed of the third party and provides the third party with the vehicle to thefleet 100, and notifies thefleet 100 of coordinated acceleration or deceleration if there is a change in speed. After thethird party vehicle 130 leaves thefleet 100, thefleet 100 is controlled to readjust the proper separation in step 407.

Otherwise, if it is not the case (i.e., thethird party vehicle 130 is not an emergency vehicle), in step 404, the distance between thevehicles 110 in thefleet 100 is shortened, and it is determined whether thethird party vehicle 130 cancels the intervention. If thethird party vehicle 130 is taken off intervention, i.e., thethird party vehicle 130 is not inclined to intervene in thefleet 100, thefleet 100 continues to steadily advance and readjust to the proper separation instep 408.

On the contrary, if thethird party vehicle 130 does not cancel the intervention, i.e. thethird party vehicle 130 still has a tendency to intervene in thefleet 100, instep 405, an alert is performed and it is determined whether thethird party vehicle 130 cancels the intervention. For example, the light of thevehicle 110 emits a flashing warning light or red light warning, and the speaker of thevehicle 110 emits a warning sound. If thethird party vehicle 130 is taken off intervention, i.e., thethird party vehicle 130 is not inclined to intervene in thefleet 100, thefleet 100 continues to steadily advance and readjust to the proper separation instep 408.

Conversely, if thethird party vehicle 130 is not taken out of intervention, i.e., thethird party vehicle 130 still has a tendency to intervene in thefleet 100, the separation of thevehicles 110 in thefleet 100 is increased in step 407. Specifically, in step 407, thedetection device 320 is used to estimate the third-party vehicle 130 to intervene in the driving point to adjust the distance between thefleet 100, so that the intervening driving point has an appropriate distance, and thenearest vehicle 110 senses the driving state of the third-party vehicle 130 to report thefleet 100 at any time; for example, the speed sensing device 323 senses the speed of the third party and provides the third party with the vehicle to thefleet 100, and notifies thefleet 100 of coordinated acceleration or deceleration if there is a change in speed. After thethird party vehicle 130 leaves thefleet 100, thefleet 100 is controlled to readjust the proper separation in step 407.

It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific embodiments for practicing the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention in practice.
