Obviously, the following drawings are some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0045] In the embodiments of the present invention, by providing a vehicle TBOX fault identification method and device, the technical problem of how to identify TBOX faults is solved.

[0046] To better understand the technical solutions of the present invention, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0047] As Figure 1 shown, the vehicle TBOX fault identification method of this embodiment includes:

[0048] Step S1, at a preset moment when the TBOX of the target vehicle uploads a heartbeat packet, determine whether a heartbeat packet uploaded by the target vehicle is received;

[0049] Step S2, if a heartbeat packet containing error information uploaded by the target vehicle is received, determine that the TBOX of the target vehicle has a fault;

[0050] Step S3, if a heartbeat packet uploaded by the target vehicle is not received, determine whether the network signal at the location where the target vehicle is located is normal;

[0051] Step S4, if the network signal at the location where the target vehicle is located is normal, determine that the TBOX of the target vehicle has a fault.

[0052] The vehicle TBOX fault identification method of this embodiment is applied to the cloud. Generally, under normal circumstances, the TBOX of the vehicle will regularly upload heartbeat packets to the cloud, such as once every 10s or 1min. The heartbeat packet carries the location information of the vehicle; when the TBOX has a fault, the heartbeat packet will also report error information; if the network signal at the location where the vehicle is located is abnormal and there is no network connection between the TBOX and the cloud, the cloud cannot receive the heartbeat packet.

[0053] In step S1, the target vehicle is the vehicle for which it is currently necessary to determine whether a TBOX fault has occurred, and the preset moment is the moment when the target vehicle should upload a heartbeat packet to the cloud under normal circumstances. It can be understood that if the cloud receives a normal heartbeat packet, it means that the TBOX of the vehicle is normal.

[0054] In step S2, if the target vehicle uploads a heartbeat packet containing error information, it means that the network signal at the location of the target vehicle is normal, and it can be directly determined that the TBOX of the target vehicle has a fault.

[0055] In step S3, if no heartbeat packet uploaded by the target vehicle is received, there are two possible reasons: one is that the network signal at the location of the target vehicle is abnormal; the other is that the TBOX of the target vehicle has a fault. Thus, if the situation of abnormal network signal at the location of the target vehicle can be excluded, it can be determined that the TBOX of the target vehicle has a fault. Therefore, in step S4, after determining that the network signal at the location of the target vehicle is normal, it can be determined that the TBOX of the target vehicle has a fault.

[0056] As can be seen from the above, the vehicle TBOX fault identification method of this embodiment can determine that the TBOX of the target vehicle has a fault when receiving a heartbeat packet containing error information uploaded by the target vehicle, and can also determine that the TBOX of the target vehicle has a fault when no heartbeat packet uploaded by the target vehicle is received and the network signal at the location of the target vehicle is normal, realizing the active identification of vehicle TBOX faults, which is beneficial to timely notify the after-sales to contact the vehicle owner to promote the solution of the fault and improve the user experience.

[0057] In step S3, for determining whether the network signal at the location of the target vehicle is abnormal, the most direct way is for the cloud to notify the after-sales to contact the network operator for inquiry, but this way is not an active judgment by the cloud. It can be understood that if the cloud can receive the heartbeat packets uploaded by other vehicles in the same network environment as the target vehicle, it means that the network signal at the location of the target vehicle is normal. Thus, in step S3 of this embodiment, determining whether the network signal at the location of the target vehicle is abnormal may include:

[0058] Obtain the first historical location of the target vehicle when the last heartbeat packet uploaded by the target vehicle is received;

[0059] If heartbeat packets uploaded by other vehicles whose distance from the first historical location is less than the first preset distance are received, it is determined that the network signal at the location of the target vehicle is normal.

[0060] Since the vehicle sends heartbeat packets at regular intervals and the time interval is short, the distance between the first historical position and the actual position of the target vehicle is relatively close, and it can be approximately considered that the first historical position is the actual position of the target vehicle. If the distance from the first historical position is less than the first preset distance, a circular area with the first historical position as the center and the first preset distance as the radius can be determined. The network signals at all points in this circular area can be considered the same as the network signal at the position where the target vehicle is located. In this way, by receiving the heartbeat packets uploaded by other vehicles within the circular area, it can be determined that the network signal at the position where the target vehicle is located is normal. Of course, there may be no other vehicles within the above circular area. In this case, it can only be considered that the network signal at the position where the target vehicle is located is abnormal, and it is impossible to determine whether the TBOX of the target vehicle has a fault, and the after-sales service needs to be notified to contact the vehicle owner for confirmation.

[0061] In this embodiment, the first preset distance can be directly set, such as 5 km. However, there may be differences in the network signals at all points within 5 km. Considering that the network signals at all points in the 5-km circular area are the same as the network signal at the position where the target vehicle is located, the possibility of misjudgment is relatively high. For this reason, in this embodiment, the step of determining the first preset distance can be selected, including:

[0062] Obtain the second historical position of the target vehicle when the heartbeat packet uploaded by the target vehicle was received penultimately;

[0063] Take the distance between the first historical position and the second historical position as the first preset distance.

[0064] Since the vehicle sends heartbeat packets at regular intervals, the time interval between the penultimate and the last time the heartbeat packet was received is the same as the time interval between the last time the heartbeat packet was received and the current time. In this embodiment, it can be considered that the target vehicle travels at the same speed from the second historical position to the first historical position and from the first historical position to the current actual position. In this way, the distance traveled by the target vehicle from the moment when the last heartbeat packet was received to the current time can be considered to be the distance between the first historical position and the second historical position. Thus, no matter in which direction the target vehicle travels after the last heartbeat packet was received, it can be determined that the current actual position of the target vehicle must be within the circular area with the first historical position as the center and the first preset distance as the radius. The circular area determined in this way, which has the same network signal as the position where the target vehicle is located, is more accurate, and it can more accurately determine whether the network signal at the position where the target vehicle is located is normal. Of course, the first preset distance determined here is smaller, and the possibility that there are no other vehicles within the circular area is greater, and the possibility that it is impossible to determine whether the TBOX of the target vehicle has a fault is also greater.

[0065] To reduce the possibility that there are no other vehicles in the circular area, this embodiment also provides another method for determining the preset distance threshold, including: obtaining the second historical position of the target vehicle when the heartbeat packet uploaded by the target vehicle was received penultimately; determining the distance between the first historical position and the second historical position; and taking the sum of the distance and the second preset distance as the first preset distance.

[0066] As Figure 2 shown, no matter in which direction the target vehicle travels after receiving the heartbeat packet for the last time, it can be determined that the current actual position of the target vehicle must be within the circular area with the first historical position as the center and the distance between the first historical position and the second historical position as the radius. The second preset distance (such as 5 km) is the distance further expanded on the basis of this circular area, so that the determined area with the same network signal as the position of the target vehicle is larger, and the possibility of there being no other vehicles is smaller, which can reduce the possibility of being unable to determine whether the TBOX of the target vehicle has failed.

[0067] As Figure 3 shown, this embodiment also provides a vehicle TBOX fault identification device, including:

[0072] Further, the network signal judgment module is further configured to:

[0074] If a heartbeat packet uploaded by another vehicle whose distance from the first historical position is less than the first preset distance is received, determine that the network signal at the position of the target vehicle is normal.

[0075] Further, the steps for the network signal judgment module to determine the first preset distance include:

[0076] Obtain the second historical position of the target vehicle when receiving the heartbeat packet uploaded by the target vehicle for the penultimate time;

[0077] Take the distance between the first historical position and the second historical position as the first preset distance.
