[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments only constitute a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] Exemplary method In order to solve the problem of how to more effectively reduce wind resistance for vehicle platooning, the present application provides a wind resistance kit adjustment method, which can be implemented in the form of a software algorithm. The software algorithm implementing the method can run on any device with data processing capability, such as a controller configured on a vehicle, a remote server, a smart mobile device, etc.

[0025] In one embodiment, as shown in FIG. 1 the real-time flow steps of the wind resistance kit adjustment method include: Step 101, obtaining the real-time formation mode of the vehicle formation, wherein each vehicle in the vehicle formation corresponds to a vehicle number respectively.

[0026] In this embodiment, the vehicle formation is composed of two or more vehicles. According to actual needs, the vehicle formation can adopt different formation modes, such as a lead-follow mode, a virtual structure mode, etc., wherein the lead-follow mode specifies a lead vehicle (the vehicle in the vehicle formation that is the first in the driving direction) and a following vehicle (the vehicle in the vehicle formation that follows the lead vehicle) to keep consistent with the lead vehicle by adjusting its own state (speed, spacing, etc.); the virtual structure mode regards the entire vehicle formation as a virtual rigid structure, and each vehicle is a point on the structure, keeping the relative position unchanged. During the driving process of the vehicle formation, the formation mode can be changed according to actual needs. The real-time formation mode refers to the real-time formation mode of the vehicle formation.

[0027] In this embodiment, each vehicle in the vehicle formation corresponds to a vehicle number respectively, for example, according to the division of the lead vehicle, the intermediate vehicle (the vehicle in the vehicle formation between the first and the last in the driving direction) and the tail vehicle (the vehicle in the vehicle formation that is the last in the driving direction), the vehicle numbers are respectively recorded as F for the lead vehicle, M1…Mn for the intermediate vehicles, and R for the tail vehicle. The vehicle numbers of different vehicle formations can be different, and when the relative positions of the vehicles in the same vehicle formation change due to the formation mode or other needs, the vehicle numbers will change accordingly. The vehicle numbers are determined based on the relative positions of the different vehicles in the vehicle formation.

[0028] Step 102, based on the vehicle number, obtaining the wind resistance kit adjustment information corresponding to each vehicle in the vehicle formation in the real-time formation mode respectively.

[0029] In this embodiment, the vehicle number can ensure the relative position of each vehicle in the vehicle formation, and therefore, based on the vehicle number and in combination with the real-time formation mode, the wind resistance kit adjustment information of each vehicle can be determined. The wind resistance kit on the vehicle is a series of external components specially designed to optimize the airflow around the vehicle, thereby reducing air resistance (referred to as wind resistance), improving driving stability, and possibly improving fuel economy or electric endurance mileage. Optionally, the wind resistance kit adjustment information includes adjustment information for the angle of the wind resistance kit and the length of the wind resistance kit. Specifically, the angle of the wind resistance kit refers to the angle of each wind deflector in the wind resistance kit, and the length of the wind resistance kit refers to the length of each wind deflector in the wind resistance kit.

[0030] Step 103, based on the wind resistance kit adjustment information, adjusting the wind resistance kit of each vehicle in the vehicle formation respectively.

[0031] In this embodiment, after determining the wind resistance kit adjustment information corresponding to each vehicle in the vehicle platoon, the wind resistance kit of each vehicle in the real-time platoon mode is adjusted. Specifically, as shown in FIG. 2 The wind resistance kit adjustment information includes adjustment information for the wind resistance kit angle and the wind resistance kit length. After the control center obtains the real-time vehicle distance and the real-time vehicle speed, the vehicle number of each vehicle in the vehicle platoon (for example, the head vehicle F, the intermediate vehicle M1, …, the intermediate vehicle Mn, and the tail vehicle R) is determined in the real-time platoon mode. Based on the vehicle number, the wind resistance kit angle (for example, Angel_F, Angel_M1, …, Angel_Mn, and Angel_R) and the wind resistance kit length (for example, L_F, L_M1, …, L_Mn, and L_R) corresponding to each vehicle are determined. The above process realizes the automatic adjustment of the wind resistance kit, improves the flexibility and automation of the wind resistance kit adjustment process, improves the effect of reducing wind resistance, and reduces the overall platoon energy consumption to a greater extent.

[0032] In this embodiment, as shown in FIG. 3 For example, the vehicle is a truck, the truck includes a cab, a cargo box, and a wind resistance kit at the tail of the truck. When the wind resistance kit adjustment information includes adjustment information for the wind resistance kit angle and the wind resistance kit length, the wind resistance kit angle can be adjusted first and then the wind resistance kit length. The wind resistance kit length can be adjusted first and then the wind resistance kit angle. Only the wind resistance kit length or the wind resistance kit angle can be adjusted, thereby meeting various needs of the wind resistance kit adjustment process.

[0033] In one embodiment, the real-time platoon mode of the vehicle platoon is obtained, including: obtaining the real-time vehicle distance between any two adjacent vehicles in the vehicle platoon, and obtaining the real-time vehicle speed of each vehicle in the vehicle platoon; comparing the real-time vehicle distance and the real-time vehicle speed with the preset vehicle distance range and the preset vehicle speed range in at least one preset platoon mode, respectively, to determine the real-time platoon mode in the at least one preset platoon mode.

[0034] In this embodiment, multiple preset platooning modes are pre-set according to actual conditions and needs. During vehicle platooning, the most suitable real-time platooning mode can be automatically determined based on real-time distance and real-time speed. Specifically, based on various information such as onboard radar and navigation data from each vehicle in the platoon, the real-time speed of each vehicle during platooning can be calculated, as well as the real-time distance between any two adjacent vehicles in the platoon. Each preset platooning mode has a pre-set preset distance range (denoted as S min ~ Smax) and a preset speed range (denoted as V min ~ V max). Optionally, the preset distance range and preset speed range corresponding to each preset platooning mode are determined based on actual vehicle calibration, provided that safe distance, safe speed, and economical speed are met.

[0035] In one embodiment, the real-time distance and real-time speed are compared with preset distance ranges and preset speed ranges in at least one preset platooning mode, respectively, and a real-time platooning mode is determined in at least one preset platooning mode, including: for a first platooning mode in at least one preset platooning mode: if the real-time distance is within the preset distance range in the first platooning mode and the real-time speed is within the preset speed range in the first platooning mode, then the first platooning mode is determined to be a real-time platooning mode.

[0036] In this embodiment, when comparing the real-time vehicle distance and real-time vehicle speed with the preset vehicle distance range and preset vehicle speed range of at least one preset formation mode, if there is a first formation mode among the preset formation modes that satisfies the real-time vehicle distance being within the preset vehicle distance range of the first formation mode and the real-time vehicle speed being within the preset vehicle speed range of the first formation mode, then the first formation mode is determined to be a real-time formation mode.

[0037] In this embodiment, after determining the real-time platooning mode of the vehicle platoon, the vehicle number corresponding to each vehicle in the platoon can be determined. For example, as shown... FIG. 4 As shown, taking the implementation of this method in a remote control center as an example, the control center obtains the number of vehicles in the platoon, the information collected by the onboard radar of each vehicle in the platoon, and the navigation information of each vehicle in the platoon. Based on the radar information, navigation information, and other information, the control center calculates the real-time distance and real-time speed; then, it correlates the real-time distance and real-time speed with the platoon formations of column 1, column 2, column 4, ..., column 2, column 3, ..., column 4, ..., column 5, column 6, column 7, column 8, column 9, column 10, column 11, column 12, column 13, column 14, ..., column 15, column 16, column 17, column 18, column 19, column 10, column 11, column 12, column 13, column 14, column 15, column 16, column 17, column 18, column 19, column 10 ... nThe preset vehicle distance range (denoted as Smin ~ Smax) and the preset vehicle speed range (denoted as Vmin ~ Vmax) in each of the plurality of preset platoon modes are compared, and finally the real-time platoon mode is determined. For example, the vehicle distance between each vehicle in the vehicle platoon 1 is denoted as S1, and the vehicle speed of each vehicle is denoted as V1; the vehicle distance between each vehicle in the vehicle platoon 2 is denoted as S2, and the vehicle speed of each vehicle is denoted as V2; the vehicle distance between each vehicle in the vehicle platoon 4 is denoted as S3, and the vehicle speed of each vehicle is denoted as V3; and so on; the vehicle distance between each vehicle in the vehicle platoon 2 is denoted as Sn, and the vehicle speed of each vehicle is denoted as Vn. Based on the real-time platoon mode, the control center determines the vehicle number corresponding to each vehicle in the vehicle platoon. Optionally, under each preset platoon mode, based on real vehicle calibration, the optimal preset vehicle distance and preset vehicle speed are determined under the premise of meeting the safety distance, safety speed, and economic speed. n

[0038] In one embodiment, based on the vehicle number, the adjustment information of the wind resistance suite corresponding to each vehicle in the vehicle platoon under the real-time platoon mode is obtained, including: based on the vehicle number, the preset adjustment information set corresponding to each vehicle in the vehicle platoon under the real-time platoon mode is obtained respectively, wherein the preset adjustment information set includes at least one preset wind resistance suite adjustment information; for each vehicle in the vehicle platoon: in the preset adjustment information set, the wind resistance suite adjustment information under the real-time platoon mode is determined.

[0039] In this embodiment, the vehicle number corresponding to each vehicle in the vehicle platoon under the real-time platoon mode is fixed, and through the vehicle number, the preset adjustment information set corresponding to each vehicle in the vehicle platoon under the real-time platoon mode can be accurately obtained. The preset adjustment information set is a plurality of preset wind resistance suite adjustment information pre-set by any one of experiment, simulation, etc., and each preset wind resistance suite adjustment information can adjust the wind resistance suite to different degrees. For each vehicle in the vehicle platoon, the wind resistance suite adjustment information under the real-time platoon mode is determined in the corresponding preset adjustment information set, which can process each vehicle in the vehicle platoon and improve the accuracy of the wind resistance suite adjustment information.

[0040] In one embodiment, each preset wind resistance suite adjustment information corresponds to a preset vehicle distance and a preset vehicle speed.

[0041] ​In the preset adjustment information set, the wind resistance suite adjustment information in the real-time platoon mode is determined, including: calculating a vehicle distance difference between each preset vehicle distance and a real-time vehicle distance between any two adjacent vehicles in the vehicle platoon, and calculating a vehicle speed difference between each preset vehicle speed and a real-time vehicle speed of each vehicle in the vehicle platoon; and determining preset wind resistance suite adjustment information with the minimum vehicle distance difference and the minimum vehicle speed difference as the wind resistance suite adjustment information in the real-time platoon mode.

[0042] In the embodiment, each preset wind resistance suite adjustment information corresponds to a preset vehicle distance and a preset vehicle speed, and when the wind resistance suite adjustment information is determined, the vehicle distance difference between each preset vehicle distance and a real-time vehicle distance between any two adjacent vehicles in the vehicle platoon and the vehicle speed difference between each preset vehicle speed and a real-time vehicle speed of each vehicle in the vehicle platoon can be calculated by the difference optimization method. The preset wind resistance suite adjustment information with the minimum vehicle distance difference and the minimum vehicle speed difference is the most suitable wind resistance suite adjustment information for the current vehicle in the real-time platoon mode. The difference optimization method has simple logic and high accuracy, and is beneficial to improving the overall efficiency of the wind resistance suite adjustment.

[0043] In one embodiment, the preset adjustment information set is obtained by the following process: based on the vehicle number, each vehicle is simulated under each wind resistance suite parameter to determine the wind resistance suite parameter with the optimal energy consumption under different preset vehicle speeds and preset vehicle distances as the preset wind resistance suite adjustment information.

[0044] In the embodiment, for the preset adjustment information set corresponding to the real-time platoon mode or any one of the preset platoon modes, the preset adjustment information set can be obtained by simulation. Specifically, as shown in FIG. 2, the preset adjustment information set is obtained by simulation. FIG. 5As shown, in any one formation mode, a computational fluid dynamics (CFD) calculation model of the vehicle formation is established. Based on the formation mode, a matrix is formed for each vehicle number, with respect to multiple vehicle speeds S (for example, S1, S2, S3…Sn), multiple vehicle distances V (for example, V1, V2, V3…Vn), multiple wind resistance kit angles Angle (for example, Angle1_F, Angle2_F, Angle3_F…Anglen_F, Angle1_M1, Angle2_M1, Angle3_M1…Anglen_M1, Angle1_Mn, Angle2_Mn, Angle3_Mn…Anglen_Mn, Angle1_R, Angle2_R, Angle3_R…Anglen_R), and multiple wind resistance kit lengths L, and so on. A Design of Experiments (DOE) simulation calculation is performed for each matrix. For each vehicle number, a matrix of wind resistance kit angles Angel and wind resistance kit lengths L corresponding to the lowest energy consumption of the vehicle formation at different vehicle speeds and vehicle distances is found, which is the preset wind resistance kit adjustment information. The preset wind resistance kit adjustment information is stored for subsequent use.

[0045] In this embodiment, in order to reduce the DOE calculation amount, the wind resistance kit angle and the wind resistance kit length of the middle vehicle can be the same as those of the front vehicle. Further, the wind resistance kit angle and the wind resistance kit length can be divided into different numerical gears according to actual conditions and requirements, thereby further reducing the calculation amount.

[0046] In one embodiment, after adjusting the wind resistance kit of each vehicle in the vehicle formation based on the wind resistance kit adjustment information, the method further includes: reacquiring the latest formation mode of the vehicle formation; if the latest formation mode is different from the real-time formation mode, reacquiring the latest wind resistance kit adjustment information corresponding to each vehicle in the vehicle formation in the latest formation mode based on the vehicle number; and adjusting the wind resistance kit of each vehicle in the vehicle formation again based on the latest wind resistance kit adjustment information.

[0047] In this embodiment, the method can be repeatedly implemented during the driving of the vehicle formation, so as to timely and flexibly adjust the formation mode of the vehicle formation according to the actual road conditions. After the formation mode changes, the angle of each deflector plate of the wind resistance kit is automatically adjusted based on the latest formation mode, the flexibility and real-time performance of the wind resistance kit adjustment are improved, the air resistance received by the overall truck formation is always the lowest, and the overall formation energy consumption is maximally reduced.

[0048] In the present application, a real-time formation mode of a vehicle formation is acquired, wherein each vehicle in the vehicle formation corresponds to a vehicle number; based on the vehicle number, wind resistance kit adjustment information corresponding to each vehicle in the vehicle formation in the real-time formation mode is acquired; and based on the wind resistance kit adjustment information, the wind resistance kit of each vehicle in the vehicle formation is adjusted. In the above process, the adjustment of the wind resistance kit is flexibly adjusted according to the real-time formation mode of the vehicle formation, and the wind resistance kit of each vehicle in the vehicle formation in the real-time formation mode is adjusted in a targeted manner, and can be automatically adjusted. Compared with adjusting the wind resistance by adjusting the vehicle distance, the real-time situation of the vehicle formation can be better adapted to, so as to improve the effect of reducing wind resistance and reduce the overall formation energy consumption to a greater extent.

[0049] Further, the scheme provided by the method has less dependence on the gap distance between vehicles, and can effectively reduce wind resistance under a larger safety distance from the front vehicle, while ensuring the energy consumption of the vehicle formation and improving the safety redundancy distance of the vehicle formation and the driving safety of the vehicle formation. The angle and length of the wind resistance kit can be adaptively adjusted, the adjustment parameters are pre-stored after being calibrated by a CFD model, the wind resistance reduction effect is good, and the certainty is high.
