[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.
[0036] In the related art, the duration of the time period for processing data is set according to the experience of engineers, resulting in a reduction in the safety of the vehicle due to unreasonable processing time. As an example, the main vehicle is traveling at normal speed or at high speed, and the number of associated vehicles of the main vehicle is relatively small, but the vehicle data of the associated vehicles of the main vehicle must be processed in the shortest possible time to obtain the processing results of other vehicle data. In this way, it is possible to timely determine whether there is a driving risk, and to timely issue an early warning when it is determined that there is a driving risk to ensure the safety of the vehicle's driving. If the processing time is set too long, it takes a long time to get the processing results of other vehicle data. The processing results of other vehicle data cannot be obtained in time. As an example, the main vehicle is traveling at an intersection, and the number of associated vehicles of the main vehicle is relatively large. If the processing time is set too short, only the vehicle data of a part of the threatening vehicle is collected, and the accuracy of the processing results of other vehicle data of a part of the threatening vehicle is low, resulting in a reduction in the safety of the main vehicle.
[0037] The method for dynamically adjusting the signal output time window through V2V communication data provided by the embodiment of the present disclosure can determine the duration of the second sub-target time window period of the target time window period according to the number of associated vehicles in the first sub-target time window period corresponding to the target time window period. Considering the correlation between the number of associated vehicles and the time period for processing the vehicle data of the vehicle, that is, the duration of the second sub-target time window period of the target time window period, the duration that is more suitable for processing the vehicle data of the number of associated vehicles is determined according to the number of associated vehicles in the first sub-target time window period corresponding to the target time window period. The determined time period for processing the vehicle data of the vehicle, that is, the duration of the second sub-target time window period of the target time window period is more appropriate. Avoid the situation where the length of the time period set by the engineer for processing data is inappropriate, which reduces the safety of the vehicle. Improve the safety of the vehicle.
[0038] refer to Figure 1 , which is a schematic diagram showing an example of an associated vehicle of the host vehicle when the host vehicle is traveling at a normal speed or a high speed.
[0039] When the host vehicle is traveling at normal speed or high speed, the host vehicle and the associated vehicle perform V2V communication through the PC5 protocol.
[0040] Figure 1 The communication range of V2V communication using the PC5 protocol is exemplarily shown as a circle with the position of the host vehicle as the center. Multiple associated vehicles of the host vehicle are within the communication range of PC5.
[0041] refer to Figure 2 , which shows a schematic diagram of an example of an associated vehicle of a main vehicle when the main vehicle is traveling at an intersection.
[0042] When the main vehicle is driving at an intersection, the main vehicle and the associated vehicle perform V2V communication through the PC5 protocol.
[0043] Figure 2 The communication range of V2V communication using the PC5 protocol is exemplarily shown as a circle with the position of the host vehicle as the center. Multiple associated vehicles of the host vehicle are within the communication range of PC5.
[0044] refer to Figure 3 , which shows a flow chart of a method for dynamically adjusting a signal output time window through V2V communication data provided by an embodiment of the present disclosure.
[0045] In step S301, the target vehicle determines the number of associated vehicle data received within the first sub-target time window period of the target time window period, and determines the number of associated vehicle data received within the first sub-target time window period of the target time window period as the number of associated vehicles corresponding to the first sub-target time window period of the target time window period.
[0046] The target vehicle may be any vehicle to which the method provided in the embodiments of the present disclosure may be applied.
[0047] The associated vehicle data is sent by the associated vehicle of the target vehicle. The associated vehicle data is vehicle data generated by the associated vehicle of the target vehicle.
[0048] The duration of the first sub-target time window period of the target time window period may be preset.
[0049] For a vehicle, if the target vehicle receives the vehicle data of the vehicle sent by the target vehicle within the first sub-target time window period of the target time window period, then the vehicle is an associated vehicle of the target vehicle, and the vehicle data of the vehicle is associated vehicle data.
[0050] It should be noted that the target vehicle may be referred to as a host vehicle (HV), and the associated vehicle of the target vehicle may be referred to as a remote vehicle (RV).
[0051] The target vehicle and its associated vehicles can perform V2V communication via the PC5 protocol.
[0052] In a possible implementation manner, the vehicle data of the associated vehicle includes at least one of the following items: GNSS data, CAN data, and PC5 data.
[0053] In step S302, the target vehicle determines the number of associated vehicles corresponding to the first sub-target time window period of the target time window period, determines the duration of the second sub-target time window period of the target time window period, and determines the second sub-target time window period of the target time window period.
[0054] Among them, the starting time of the second sub-target time window period of the target time window period is the ending time of the first sub-target time window period of the target time window period.
[0055] In one possible implementation, in step S302, in order to determine the duration of the second sub-target time window period of the target time window period, the product of the processing duration of a single associated vehicle data and the number of associated vehicles corresponding to the first sub-target time window period of the target time window period can be calculated, and the product or the sum of the product and a preset duration increase can be determined as the duration of the second sub-target time window period of the target time window period.
[0056] The single associated vehicle data processing time indicates: the time required to process one associated vehicle data. The single associated vehicle data processing time may be preset.
[0057] In one possible implementation, in step S302, in order to determine the duration of the second sub-target time window period of the target time window period, the duration of the second sub-target time window period of the target time window period is determined according to the number of associated vehicles corresponding to the first sub-target time window period of the target time window period, the data processing duration of a single associated vehicle, and the distance change information of the first sub-target time window period corresponding to the target time window period, wherein the distance change information of the first sub-target time window period corresponding to the target time window period is determined according to the distance information of the first sub-target time window period corresponding to the target time window period and the distance information of the first sub-target time window period corresponding to the previous time window period of the target time window period.
[0058] The end time of the target time window period is the start time of the previous time window period of the target time window period. The duration of the previous time window period of the target time window period is the same as the duration of the target time window period. The duration of the first sub-target time window period of the target time window period is the same as the duration of the first sub-target time window period of the previous time window period of the target time window period.
[0059] If the target time window period is the first time window period, that is, the earliest time window period, the distance change information of the first sub-target time window period corresponding to the target time window period may be 1.
[0060] If the target time window period is not the first time window period, the distance change information of the first sub-target time window period corresponding to the target time window period can be determined based on the distance information of the first sub-target time window period corresponding to the target time window period and the distance information of the first sub-target time window period corresponding to the previous time window period of the target time window period.
[0061] The distance information corresponding to the first sub-target time window period of the target time window period can be: the average value of the distance between the position of the vehicle to which the associated vehicle data received within the first sub-target time window period of the target time window period belongs at the starting time of the target time window period and the position of the target vehicle at the starting time of the target time window period.
[0062] The distance information corresponding to the first sub-target time window period of the previous time window period of the target time window period can be: the average value of the distance between the position of the vehicle to which the associated vehicle data received in the first sub-target time window period of the previous time window period of the target time window period belongs at the starting time of the previous time window period of the target time window period and the position of the target vehicle at the starting time of the previous time window period of the target time window period.
[0063] In a possible implementation, the following formula may be used to calculate the distance between the target vehicle and the associated vehicle:
[0064] D = 2Rarcsin((sin(a / 2) 2 +cos(HV _lat )cos(RV _lat )sin(b / 2) 2 ))
[0065] a=HV _lat -RV _lat
[0066] b=HV _long -RV _long
[0067] Among them, R = 6378127m represents the radius of the earth, HV _lat RV _lat Represents the latitude of the target vehicle and the associated vehicle, HV _long RV _long Represent the longitude of the target vehicle and the associated vehicle respectively.
[0068] If the distance information of the first sub-target time window period corresponding to the target time window period is less than the distance information of the first sub-target time window period corresponding to the previous time window period of the target time window period, then the distance change information of the first sub-target time window period corresponding to the target time window period indicates that the distance between the vehicle to which the received associated vehicle data belongs and the target vehicle becomes smaller.
[0069] If the distance information of the first sub-target time window period corresponding to the target time window period is greater than the distance information of the first sub-target time window period corresponding to the previous time window period of the target time window period, then the distance change information of the first sub-target time window period corresponding to the target time window period indicates that the distance between the vehicle to which the received associated vehicle data belongs and the target vehicle has increased.
[0070] In a possible implementation, determining the duration of a second sub-target time window period of a target time window period according to the number of associated vehicles of a first sub-target time window period corresponding to the target time window period, the processing duration of a single associated vehicle data, and the distance change information of the first sub-target time window period corresponding to the target time window period includes: multiplying the number of associated vehicles of the first sub-target time window period corresponding to the target time window period by the processing duration of a single associated vehicle data to obtain a first product of the first sub-target time window period corresponding to the target time window period; when the distance change information of the first sub-target time window period corresponding to the target time window period indicates that the received associated vehicle data belongs to the vehicle When the distance between the first sub-target time window period and the target vehicle decreases, the first product is multiplied by the first value to obtain a second product of the first sub-target time window period corresponding to the target time window period, wherein the first value is greater than 0 and less than 1; when the distance change information of the first sub-target time window period corresponding to the target time window period indicates that the distance between the vehicle to which the received associated vehicle data belongs and the target vehicle increases, the first product is multiplied by the second value to obtain a second product of the first sub-target time window period corresponding to the target time window period, wherein the second value is greater than 1; according to the second product of the first sub-target time window period corresponding to the target time window period, the duration of the second sub-target time window period of the target time window period is determined. The second product of the first sub-target time window period corresponding to the target time window period can be determined as the duration of the second sub-target time window period of the target time window period.
[0071] In one possible implementation, determining the duration of the second sub-target time window period of the target time window period based on the second product of the first sub-target time window period corresponding to the target time window period includes: multiplying the second product of the first sub-target time window period corresponding to the target time window period by a proportional constant to obtain the duration of the second sub-target time window period of the target time window period.
[0072] In step S303, the target vehicle processes each associated vehicle data received within the first sub-target time window period of the target time window period within the second sub-target time window period of the target time window period to obtain other vehicle data processing results corresponding to the target time window period.
[0073] refer to Figure 4 , which is a schematic diagram showing an example of a target time window period.
[0074] The duration of the target time window period is recorded as t. t=n+1 milliseconds. n is greater than 100.
[0075] The target time window period is composed of a first sub-target time window period of the target time window period, a second sub-target time window period of the target time window period, a second sub-target time window period of the target time window period, and a third sub-target time window period of the target time window period.
[0076] The duration of the first sub-target time window period of the target time window period is 100 milliseconds, and the first sub-target time window period corresponding to the target time window period is: the time period from the start time of the target time window period to the time period when the time interval between the start time of the target time window period and the start time of the target time window period is the 100th millisecond. The target vehicle receives the associated vehicle data within the first sub-target time window period of the target time window period.
[0077] The duration of the second sub-target time window period of the target time window period is n milliseconds. The target vehicle processes each received associated vehicle data within the second sub-target time window period of the target time window period to obtain other vehicle data processing results corresponding to the target time window period.
[0078] The duration of the third sub-target time window period of the target time window period is 1 millisecond. The target vehicle outputs other vehicle data processing results corresponding to the target time window period within the third sub-target time window period of the target time window period.
